In the case of malaria, infection of man occurs by mosquito bites, during
which
"sporozoites" are introduced into the human bloodstream. Sporozoites travel
through the
bloodstream, and eventually reach and penetrate parenchyma) cells of the liver
(sporozoites can
remain in the blood for up to 1 hour).
The preerythrocytic cycle, the first cycle of growth and reproduction, lasts
about one week
and takes place in the liver. The preerythrocytic cycle liberates several
thousand merozoites, which
then pass into the blood.
The merozoites parasitize erythrocytes. Growth and reproduction take place in
red blood cells,
bringing about rhythmic fever attacks and other symptoms as the number of
parasites in the blood
increases. In the course of the erythrocytic growth-cycle, upon entering a red
cell, the parasite
assumes a ring form with a central vacuole. After about 6 hours, the vacuole
gradually disappears
as the parasite increases in size until it nearly fills the red cell. During
the last 12 hours of the
growth cycle, nuclear fission occurs from which, on average, about sixteen
merozoites are formed.
The growing parasite is termed a trophozoite and, after nuclear fission has
started, it is called a
schizont.

The malaria parasite feeds on hemoglobin, utilizing the protein portion of the
molecule and
leaving the heme portion, which accumulates to form malarial pigment. It has
been shown by EM
that the parasite feeds by phagocytosis, engulfing red cell cytoplasm;
digestion takes place in food
vacuoles, where the pigment accumulates until it is released into the plasma
when the host cell
ruptures and the merozoites escape. Shortly after the parasite has started
reproducing in the blood,
the sexual forms or gametocytes begin to appear in the red cells. Gametocytes
may survive for
several days in the mammalian host, but they cannot develop further unless
they are ingested by a
suitable mosquito host. The single nucleus of the gametocyte distinguishes it
from the fully-grown
asexual forms.
Sleeping sickness is caused by T. gambiense and T. rhodesiense and is
transmitted from
man to man or from animals to man by tsetse flies (Glossing). In the mammalian
host, the
organisms inhabit the blood but may penetrate other organs where they occur in
intercellular
spaces. In a drop of blood, the trypanosomes appear as minute, wriggling
objects.
When a tsetse fly feeds, its toothed proboscis tears the skin, causing a small
hemorrhage to
form. If trypanosomes are present, they are sucked into the gut of the fly
with the blood drawn up
from this pool. For the first few days after an infective feed, the
trypanosomes are found in the
midgut. Then some travel forwards to the proventriculus. For development to be
successful, some
must pass right forward to near the tip of the proboscis where the opening of
the salivary duct is
located. They must then pass up the duct to the salivary glands where forms
develop which are
infective to the mammal. These are called metacyclic trypanosomes because they
appear at the end
of the developmental cycle. Reproduction takes place at all sites in the fly.
The time required for
this cycle is 2-3 weeks or even longer. Not only do the trypanosomes alter in
morphology in the
insect host, but they also differ physiologically from the blood stream forms.
If a tsetse fly harboring a mature infection bites man, metacyclic
trypanosomes may be
injected along with saliva. In the early stages of an infection, the parasites
may be found in the
blood. A characteristic feature is that the number of trypanosomes builds up
to a peak and then
declines, and these cycles are repeated. The trypanosomes stimulate the host
to produce antibody,
which agglutinates and lyses the organisms. Some of the trypanosomes become
resistant to
antibody and so a new population develops of different antigenic type; these
flourish until specific
antibody is again formed to destroy them. At later stages of the infection,
the trypanosomes
become scarce or absent from the blood but invade the central nervous system
to cause sleeping
sickness.
Trypanosomes can establish and develop in a wide range of mammalian species,
and have
been isolated from many species of African game animals. In these hosts, the
association seems to
be a benign one and the mammal remains in good health. But the same
trypanosomes in man or in
2

WO 00/32201 PCT/US99/28079
man's domestic animals are highly pathogenic. Trypanosomiasis of domestic
animals is an urgent
problem in large areas of Africa where stock cannot be reared because of the
piesence of tsetse
flies and game animals.
Chagas disease (American Trypanosomiasis) is caused by T. cruzi. It is
transmitted by
blood-feeding insects of the family Triatomidae.
After infection in man, the parasite soon leaves the blood and settles in
tissues, most
frequently in cardiac, striated or smooth muscle. Here they lose their
flagella and round up. Next,
they multiply and clusters of several hundred cells may be formed, displacing
muscle fibers. After
a time, the colony starts to disperse; the cells elongate, each develops a
flagellum and the new
trypanosomes enter the circulation. The trypanosomes remain in the circulation
for several days
and then again disappear into the tissues to undergo another reproductive
cycle. In chronic
infections, the tissue phase predominates, since the blood forms can rarely be
detected.
If an insect feeds on blood containing trypanosomes, these trypanosomes become
established first in the midgut. In the midgut, the trypanosomes multiply
rapidly and within a few
days some pass into the hindgut and infective forms begin to appear in the
feces. In contrast to the
African trypanosomes, where the infective forms are situated anteriorly in the
vector and are
introduced into man by inoculation, the infective forms of T. cruzi are
located at the posterior end
of the vector's gut and infection is by contamination. Triatomid insects
ingest a large amount of
blood relative to their body weight and the ingested blood is concentrated by
fluid excretion while
the insect feeds. In this way, infective trypanosomes are deposited on the
skin of the host. The
trypanosomes cannot penetrate unbroken skin but may gain entry through the
puncture wound.
Since the insects are nocturnal and feed in the facial areas, the trypanosomes
are commonly
smeared into eyes, mouth or nose where they penetrate mucous membranes.
T. cruzi develops in several species of insects, all of which function as
hosts. If ten insects
were allowed to feed on an infected person, all ten would probably become
infected. Laboratory
reared or "clean" insects are often used in diagnosis.
T. cruzi has been found in many species of wild animals and in reduviid
insects in Central
and South America and in some of the Southern states of the USA. Human
infection in the USA is
rare, but in parts of Central and South America, the incidence of infection in
man may be as high
as 20 per cent. It has been established that some 35 million people are at
risk to the infection. The
infection may be spread from man to man or from animals to man. Domestic dogs
and cats are
reservoirs in urban areas. Drugs that are effective against the African
trypanosomes have no action
on human infections with T. cruzi; no curative drugs have yet been discovered
that combat this
parasite.

a basic or acidic
group, e.g., lysine, arginine or giutamic acid, or a neutral group such as
glycine, serine, threonine,
alanine, isoleucine, or ieucine. Salts are usually biologically compatible or
pharmaceutically

(-O-), nitrogen (-NX-) or sulfur (-S-) where X is -H, a protecting group or C

Examples are as described for heterocycle.
Protectine rouos. Various groups that the formula 1, 2A or 2B compounds may
comprise
include, e.g., substituted alkyl groups, substituted alkenyl groups, esters or
substituted
heterocycles, which can contain one or more reactive moieties such as
hydroxyl, or thiol.
Intermediates used to make formula 1 or formula 2A or 2B compounds may be
protected as is
apparent in the art. Noncyclic and cyclic protecting groups and corresponding
cleavage reactions
are described in "Protective Groups in Organic Chemistry", Theodora W. Greene
(John Wiley &
Sons, Inc., New York, 1991, ISBN 0-471-62301-6) (hereafter "Greene"). In the
context of the
present invention, these protecting groups are groups that can be removed from
the molecule of the
invention without irreversibly changing the covalent bond structure or
oxidation/reduction state of
the remainder of the molecule. For example, the protecting group, -X, that is
bondedZo a -OX or -
NHX group can be removed to form -OH or -NH2, respectively, without affecting
other covalent
bonds in the molecule. At times, when desired, more than one protecting group
can be removed at
a time, or they can be removed sequentially. In compounds of the invention
containing more than
one protecting group, the protecting groups are the same or different.
Protecting groups are intended to be removed by known procedures, although it
will be
understood that the protected intermediates fall within the scope of this
invention. The removal of
the protecting group may be arduous or straightforward, depending upon the
economics and nature
of the conversions involved. In general, one will use a protecting group with
exocyclic amines or
with carboxyl groups during synthesis of a formula 1 compound. For most
therapeutic applications
amine groups should be deprotected. Protecting groups commonly are employed to
protect against
covalent modification of a sensitive group in reactions such as alkylation or
acylation. Ordinarily,
protecting groups are removed by, e.g. hydrolysis, elimination or aminolysis.
Thus, simple
functional considerations will suffce to guide the selection of a reversible
or an irreversible
protecting group at a given locus on the invention compounds. Suitable
protecting groups and
criteria for their selection are described in T.W. Greene and P.G.M. Wuts,
Eds. "Protective Groups
in Organic Synthesis" 2nd edition, Wiley Press, at pps. 10-142, 143-174, 175-
223, 224-276, 277-
308, 309-405 and 406-454, which is incorporated herein by reference.
Determination of whether a group is a protecting group is made in the
conventional
manner, e.g., as illustrated by Kocienski, Philip J.; "Protecting Groups"
(Georg Thieme Verlag
Stuttgart, New York, 1994) (hereafter "Kocienski"}, Section 1.1, page 2, and
Greene Chapter 1,
pages 1-9; and U.S. patent 5763483, all of which are incorporated herein by
reference. In
particular, a group is a protecting group if when, based on mole ratio, 90% of
that protecting group
has been removed by a deprotection reaction, no more than 50%, preferably 25%,
more preferably
14


CA 02356539 2001-05-23
WO 00/32201 PCT/US99/28079
I 0%, of the deprotected product molecules of the invention have undergone
changes to their
covalent bond structure or oxidation/reduction state other than those
occasioned by the removal of
the protecting group. When multiple protecting groups of the same type are
present in the
molecule, the mole ratios are determined when all of the groups of that type
are removed. When
multiple protecting groups of different types are present in the molecule,
each type of protecting
group is treated (and the mole ratios are determined) independently or
together with others
depending on whether the deprotection reaction conditions pertinent to one
type are also pertinent
to the other types present. In one embodiment of the invention, a group is a
protecting group if
when, based on mole ratio determined by conventional techniques, 90% of that
protecting group
has been removed by a conventional deprotection reaction, no more than 50%,
preferably 25%,
more preferably 10%, of the deprotected product molecules of the invention
have undergone
irreversible changes to their covalent bond structure or oxidation/reduction
state othefthaa those
occasioned by the removal of the protecting group. Irreversible changes
require chemical reactions
(beyond those resulting from aqueous hydrolysis, acid/base neutralization or
conventional
separation, isolation or purification) to restore the covalent bond structure
or oxidation/reduction
state of the deprotected molecule of the invention.
Protecting groups are also described in detail together with general concepts
and specific
strategies for their use in Kocienski, Philip J.; "Protecting Groups" (Georg

Stereoisomers. The formula 1 and fonmula 2A or 2B compounds include enriched
or
resolved optical isomers at any or all asymmetric atoms as are apparent from
the depictions. Both
racemic and diasteromeric mixtures, as well as the individual optical isomers
can be isolated or
synthesized so as to be substantially free of their enantiomeric or
diastereomeric partners, and
these are all within the scope of the invention. Chiral centers may be found
in invention
compounds at, for example, RI, R2 or R4.
One or more of the following methods are used to prepare the enantiomerically
enriched
or pure isomers herein. The methods are listed in approximately their order of
preference, i.e.; one
ordinarily should employ stereospecific synthesis from chiral precursors
before chromatographic
resolution before spontaneous crystallization.
Stereospecific synthesis is described in the examples. Methods of this type
conveniently
are used when the appropriate chiral starting material is available and
reaction steps are chosen that
do not result in undesired racemization at chiral sites. One advantage of
stereospecific synthesis is
that it does not produce undesired enantiomers that must be removed from the
final product,
19


CA 02356539 2001-05-23
WO 00/32201 PCT/US99/28079
thereby lowering overall synthetic yield. In general, those skilled in the art
would understand what
starting materials and reaction conditions should be used to obtain the
desired enantiomerically
enriched or pure isomers by stereospecific synthesis.
If a suitable stereospecific synthesis cannot be empirically designed or
determined with
S routine experimentation then those skilled in the art would turn to other
methods. One method of
' general utility is chromatographic resolution of enantiomers on chiral
chromatography resins.
These resins are packed in columns, commonly called Pirkle columns, and are
commercially
available. The columns contain a chiral stationary phase. The racemate is
placed in solution and
loaded onto the column, and thereafter separated by HPLC. See for example,
Proceedings
Chromatographic Society - International Symposium on Chiral Separations, Sept.
3-4, 1987, which
is incorporated herein by reference. Examples of chiral columns that could be
used to screen for
the optimal separation technique would include Diacel Chriacel OD, Regis
Pirkle Co4alent D-
phenylglycine, Regis Pirkle Type 1 A, Astec Cyclobond II, Astec Cyclobond III,
Serva Chiral D-
DL=Daltosil 100, Bakerbond DNBLeu, Sumipax OA-1000, Merck Cellulose Triacetate
column,
Astec Cyciobond I-Beta, or Regis Pirkle Covalent D-Naphthylalanine. Not all of
these columns
are likely to be effective with every racemic mixture. However, those skilled
in the art understand
that a certain amount of routine screening may be required to identify the
most effective stationary
phase. When using such columns it is desirable to employ embodiments of the
compounds of this
invention in which the charges are not neutralized, e.g., where acidic
functionalities such as
carboxyl are not esterified or amidated.
Another method entails converting the enantiomers in the mixture to
diasteriomers with
chiral auxiliaries and then separating the conjugates by ordinary column
chromatography. This is a
very suitable method, particularly when the embodiment contains a free
hydroxyl that will form a
salt or covalent bond to a chiral auxiliary. Chirally pure amino acids,
organic acids or
organosulfonic acids are all worthwhile exploring as chiral auxiliaries, all
of which are well known
in the art. Salts with such auxiliaries can be formed, or they can be
covalently (but reversibly)
bonded to the functional group.
Enzymatic resolution is another method of potential value. In such methods one
prepares
covalent derivatives of the enantiomers in the racemic mixture, generally
lower alkyl esters, and
then exposes the derivative to enzymatic cleavage; generally hydrolysis. For
this method to be
successful an enzyme must be chosen that is capable of stereospecific
cleavage, so it is frequently
necessary to routinely screen several enzymes. If esters are to be cleaved,
then one selects a group
of esterases, phosphatases, and lipases and determines their activity on the
derivative. Typical
esterases are from liver, pancreas or other animal organs, and include porcine
liver esterase.


CA 02356539 2001-05-23
WO 00/32201 PCT/US99/28079
If the enatiomeric mixture separates from solution or a melt as a
conglomerate, i.e., a
mixture of enantiomerically pure crystals, then the crystals can be
mechanically separated, thereby
producing the enantiomerically enriched preparation. This method, however, is
not practical for
large-scale preparations and is of limited value for true racemic compounds.
Asymmetric synthesis is another technique for achieving enantiomeric
enrichment. For
example, a chiral protecting group is reacted with the group to be protected
and the reaction
mixture allowed to equilibrate. If the reaction is enantiomerically specific
then the product will be
enriched in that enantiomer.
Further guidance in the separation of enantiomeric mixtures can be found, by
way of
example and not limitation, in "Enantiomers, Racemates, and resolutions", Jean
Jacques, Andre
Collet, and Samuel H. Wilen (Krieger Publishing Company, Malabar, FL, 1991,

Embodiments include compositions that transiently occur when a method step or
operation
is performed. For example, when a formula 1 compound is contacted with an
excipient, e.g.,
water, a cyciodextrin, a PEG, an alcohol, propylene glycol, benzyl alcohol or
benzyl benzoate, the
composition before addition of one ingredient with another is a non-homogenous
mixture. As the
ingredients are contacted, the mixture's homogeneity increases and the
proportion of ingredients
relative to each other approaches a desired value. Thus, some compositions as
disclosed herein,
optionally contain less than about 3% w/w water, e.g., less than 0.5% w/w
water, can comprise
about 0.0001-99% w/w of a formula 1 compound such as l6oc-bromoepiandrosterone
and one or
more excipients. These transient compositions are intermediates that
necessarily arise when one
makes an invention composition or formulation and they are included in
invention embodiments to
the extent that they are patentable.

Metabolites. Also falling within the scope of this invention are the in vivo
metabolites of
the compounds of the invention, to the extent such products are novel and
unobvious over the prior
art. Such products may result for example from the oxidation, reduction,
hydrolysis, amidation,
esterification and the like of the administered formula 1 compound, due to
enzymatic or chemical
processes. Accordingly, the invention includes novel and unobvious compounds
produced by a
process comprising contacting a compound of this invention with a subject,
e.g., a human, rodent
or a primate, for a period of time sufficient to yield a metabolic product
thereof. Such products
typically are identified by preparing a radiolabelled (e.g. C 14 or H3)
compound of the invention,
administering it parenterally or orally in a detectable dose (e.g. greater
than about 0.5 mg/kg) to an
animal such as rat, mouse, guinea pig, primate, or to a human, allowing
sufficient time for
28

metabolism to occur (typically about 30 seconds to about 30 hours) and
isolating its conversion
products from the urine, blood or other biological samples. These products are
easily isolated since
they are labeled (others are isolated by the use of antibodies capable of
binding epitopes surviving
in the metabolite). The metabolite structures are determined in conventional
fashion, e.g. by
S HPLC, MS or NMR analysis. In general, analysis of metabolites is done in the
same way as
' conventional drug metabolism studies well-known to those skilled in the art.
The conversion
products, so long as they are not otherwise found in vivo, are useful in
diagnostic assays for
therapeutic dosing of the compounds of the invention even if they possess no
therapeutic activity
of their own.

- _ Articles of manufacture. The present invention also provides articles of
manufacture
comprising, for example, packaging material, at least one unit-dosage of a
compound of the present
invention (optionally together with one or more unit-dosage of a compound
which can be
administered in a combination therapy) and a label or package insert
indicating that the compound
can be used in a method disclosed herein.
In one embodiment, an article of manufacture comprises packaging material, at
least one
unit dose of a 17-ketosteroid compound (a formula 1 compound) and a label or
package insert
indicating that the 17-ketosteroid compound (a formula 1 compound) can be used

polypropylene, and is of a size
suitable to contain the compounds) accompanying the packaging material. A
label or package
insert can be a tag or label secured to the packaging material, a label
printed on the packaging
material or a label inserted within the packaging material. The label
indicates that the
17-ketosteroid can be used in a therapy as disclosed herein, e.g., in
combination with a plasma
concentration-enhancing compound and/or a macrophage-stimulating factor. The
label can also
indicate that the compounds) have received approval from an official agency,
for example, the
U.S. Food and Drug Administration, for medical or veterinary use according to
the method. The
label may also indicate suitable administration routes, dosage regimen, and
the like. If desired, the
article may contain additional components such as at least one unit dose of a
plasma
concentration-enhancing compound or the macrophage-stimulating factor.
Methods of administration and formulations. The dosage for a particular
patient will vary
depending on factors such as the overall health of the patient, the method,
route and dose of
administration and the severity of side effects (if any). Determination of the
appropriate dose is
made by the clinician using parameters known in the art. Generally, the dose
begins with an
amount somewhat less than the optimum dose and_it is increased by small
increments thereafter
until the desired or optimum effect is achieved. The dosage of the compounds
of the invention is
suitably determined depending on the individual cases taking symptoms, age and
sex of the subject
and the like into consideration. With respect to the duration of treatment, it
is typica) for skilled
clinicians to monitor patients in order to determine when inhibition is
providing therapeutic
73


CA 02356539 2001-05-23
WO 00/32201 PCT/US99/28079
benefit, and to determine whether to increase dosage, decrease dosage,
discontinue therapy, resume
therapy or alter therapy.
The therapeutically effective dosage of any specific compound will vary
somewhat from
compound to compound and patient to patient. As a general proposition, a
dosage in the range of
from about 0.1 to about 500 mglkg will have therapeutic efficacy. Typically, a
dosage in the range
of from about 0.5 mg/kg to about 500 mg/kg will be employed. A daily dosage of
a formula 1
compound will typically comprise about 10 to about 750 mg, usually about 20 to
about 400 mg,
which may be administered as a single dose or as two or more subdoses. Such
doses or subdoses
may be administered at one or more sites or by one or more than one route of
administration. The
duration for the treatment is usually once per day for a sufficient length of
time for the patient to
become asymptomatic, or for symptoms to abate noticeably. Depending upon the
severity of the
infection in the individual patient, this may last several days, weeks, or
longer.
With regard to the frequency and duration of treatment, it is well known that
it is within
the skill of the ordinary physician to monitor a patient's condition and to
make appropriate
decisions with regard to discontinuing, interrupting and resuming treatments.
The dosages used in accordance with the invention are suitably determined
depending on
the individual cases taking symptoms, age and sex of the subject and the like
into consideration. In
addition, it !is well known that it is within the skill of ordinary artisans
to determine suitable
dosages based on the above and other factors.
In accordance with the present method, a compound of the present invention may
be
administered orally, intramuscularly (IM), intravenously (IV), or
subcutaneously (SC), with
intravenous administration being especially preferred. Although other routes
of administration can
be used, it has been, found that intravenous administration provides
surprising effectiveness. For
oral administration, the use of a plasma concentration-enhancing compound may
be of great
importance. Alternatively, the compound or salt may also be administered
intravenously or
intramuscularly as a liposomal suspension. The administration may also be in a
cyclodextrin
formulation (given orally, SC, IV or IM). Compounds of the invention and their
pharmaceutically
or physiologically, acceptable salts, are thus administered by any route
suitable to the condition to
be treated, including oral, rectal, nasal, topical (including ocular, buccal
or sublingual), vaginal,
parenteral (including subcutaneous, intramuscular,_intravenous,
intraperitoneal, intraderma(,
intrathecal, intradural and epidural) and pulmonary by aerosol. Generally, the
compounds of the
invention are administered parenterally, orally or topically. If an embodiment
is not su~ciently
orally bioavailable it can be administered by the other routes noted above.
Embodiments include formulations that comprise a liposome or lipid complex
that
comprises a formula 1 compound. Such formulations are prepared according to
known methods,

Most often, the pharmaceutical compositions useful in the present invention
will comprise
a compound of Formula 1, or a pharmaceutically acceptable salt thereof, in any
pharmaceutically
acceptable carrier. If a solution is desired, water is the carrier of choice
with respect to
water-soluble compounds or salts. In other embodiments, an organic vehicle,
such as glycerol,
ethanol, propylene glycol, polyethylene glycol, DMSO, DMS02, vegetable,
mineral oils. ethanol,
benzyl benzoate, or mixtures thereof, may be suitable. In general, the
solutions in any instance
should be sterilized in a suitable manner, preferably by filtration through a
0.22 microttfilter. The
compositions useful in the practice of the present invention may be provided
in the form of vials,
ampoules, and the like.
In some embodiments, the formula 1 compound that is present in the
compositions or that
is used in the methods disclosed herein is completely dissolved in non-aqueous
excipients.
However, in some embodiments, e.g., transient compositions or some
formulations, the formula 1
compound is partially dissolved while the remaining portion is present as a
solid, which can be a
suspension or a colloid. In related embodiments, the formula 1 compound is
incompletely
dissolved and is present as a suspension or gel.
In addition to compounds of formula 1, or their salts, the pharmaceutical
compositions
may contain other additives, such as pH adjusting additives, in particular,
agents such as acids,
bases, or buffers, including sodium lactate, sodium acetate, and sodium
gluconate. Further, such
compositions may contain microbial preservatives, such as methylparaben,
propylparaben, benzyl
alcohol and benzyl benzoate. If a multiple use vial is supplied, the
pharmaceutical composition
should likewise include such a microbial preservative. The formulations may
be, of course,
lyophilized, using techniques well known in the art.
It has been found that with respect to the practice of the method of the
present invention,

disclosed herein
will typically comprise one or more compounds of formula 1, and, the methods
disclosed herein
will utilize such compositions, which will contain one, t<vo or more of such
compounds, usually
one. While it is possible for the compounds of the invention to be
administered as purecompounds
it is preferable to present them as pharmaceutical formulations. The
formulations of the present
invention comprise at least one formula 1 compound together with one or more
acceptable carriers
or excipients and optionally other therapeutic agents, e.g., a formula 2A or
2B compound(s),
chloroquine, a chlroquine analog, a macrophage stimulating factors) and/or an
oxidation agent(s).
The one or more carriers or excipients must be "acceptable" in the sense of
being compatible with
the other ingredients of the formulation and not deleterious to the patient.
In other embodiments, a dosing regimen for a formula I compound will comprise
the use
of a relatively high induction dose, e.g., about 150-750 mg per day or about
150-750 mg per day
using an intermittent dosing schedule (such as described herein), followed by
lower maintenance
dosing, e.g., about 50-Z50 mg per day or about 50-250 mg per day on an
intermittent dosing
schedule. These embodiments may further comprise treatment with a formula 2A
or 2B compound
or another treatment as described herein.
Parenteral formulations may comprise a cyclodextrin, e.g., an ac-cyciodextrin,
a ~i-
cyclodextrin (e.g., (3-hydroxypropylcyclodextrin) or a y-cyclodextrin, which
are typically employed
in aqueous formulations, which optionally comprise one or more of a buffer, a
salt (NaCI, etc.) to,
e.g., render the solution isotonic, a bacteriostat or other excipients as
known in the art and a
formula 1 compound at a concentration of, e.g., about 5-25 mg/mL, typically
about 10-20 mg/mL.
Parenteral formulations that comprise a formula 1 compound and one or more
excipients may be
diluted into, e.g., sterile saline and infeused into a subject. Parenteral
formulations are typically
administered by, e.g., intravenous, topical or oral delivery to a subject such
as a human. For non-
aqueous formulations, one or more solvents such as propylene glycol, a PEG,
e.g., PEG 300 or
PEG 400, ethanol, and benzyl benzoate may be employed. Typical aqueous and non-
aqueous
formulations will contain about S to about 400 mg/mL of a formula I compound,
usually about 10
78


CA 02356539 2001-05-23
WO 00/32201 PCT/US99/Z8079
to about 200 mg/mL. Such parenteral formulations may be delivered orally, or
by intramuscular,
intravenous or subcutaneous injection.
In preparing compositions that comprise a formula 1 compound (and optionally
one or
more excipients), one may optionally mill or otherwise granulate the compound
to obtain a desired
particle size, before or after the formula 1 compound is contacted with one or
more excipients. For
' _ example, one may mill a formula I compound such as 16a.-
bromoepiandrosterone, to obtain an
average particle size (or diameter) of about 0.5-25 pM or about 1-10 p,M
(e.g., about 2, 5 or 10 1tM
average particle size or diameter) before contacting the milled formula 1
compound with a liquid
or solid excipient. Milled formula 1 compound is useful to facilitate
dissolution or suspension of
the formula 1 compound in one or more liquid excipients (e.g., a PEG such as
PEG 300, propylene
glycol or benzyl benzoate) or to facilitate uniformly distributing drug
substance when the milled
compound is contacted with one or more solid excipients (e.g., a filler, a
binder or a lubricant).
The compositions and formulations disclosed herein are useful in the treatment
of, or
ameliorate one or more symptoms associated with, the conditions or infections
disclosed herein.
These compositions and formulations may also be used to treat, or ameliorate
one or more
symptoms associated with, a retroviral infection such as a HIV 1 or H1V2
infection in humans. As
used herein, phrases such as "amelioration of one or more symptoms associated
with" means that
such compounds or formulations may be used to reduce replication of an
infectious agent or to
reduce the number of infectious agents that are present in a subject or to
ameliorate one or more
symptoms associated with, or caused by, the condition or infection (e.g.,
reduced fever, a shortened
duration of, or reduced level of, pain, or a noticeable reduction of or
elimination of diarrhea or
fatigue).
In addition to the ingredients particularly mentioned above the formulations
of this
invention may include other agents conventional in the art having regard to
the type of formulation
in question, for example those suitable for oral administration may include
flavoring or coloring
agents.
The present invention further provides veterinary compositions comprising at
least one
formula 1 or formula 2A or 2B compound together with a veterinary carrier
therefor. Also, the
formula 1 compound may be present in the animal's feed or water. Excipients
for veterinary
applications may include compounds, e.g., small amounts of chloroform, that
may not be generally
suitable for human use.
Veterinary carriers are materials useful for the purpose of administering the
composition to
cats, dogs, horses, mice, rats, hamsters, rabbits and other animals and may be
solid, liquid or
gaseous materials that are otherwise inert or acceptable in the veterinary art
and are compatible
79


CA 02356539 2001-05-23

with the formula 1 or formula 2A or 2B compound. These veterinary compositions
may be
administered orally, parenterally or by any other desired route, e.g., as
described herein.
Embodiments of formula 1 compounds include or exclude any subset of compounds
within
the definition of formula I, provided that at least one compound remains. For
example, a subset of
formula 1 compounds that are generally preferred and are usually included, for

The formulation was prepared by suspending BrEA in polyethylene glycol 300,
and
sequentially adding propylene glycol, benzyl benzoate, and dehydrated ethyl
alcohol to form a
solution, which was diluted to the final desired volume with additional
propylene glycol. The
procedure is described below.
The calculated amount of polyethylene glycol 300 was added to a compounding
vessel.
Then, while mixing, the calculated amount of BrEA was added to the vessel, and
mixed for at least
5 minutes to form a smooth, creamy liquid. Propylene glycol was added to the
vessel, and mixed
for a minimum of 5 minutes to form a uniform suspension. The calculated amount
of benzyl
benzoate is added to the vessel, and mixed for approximately S minutes to form
a translucent liquid
suspension. Dehydrated alcohol was added to the vessel, and mixed for
approximately 5 minutes
to form a clear, colorless solution. Propylene glycol was then added to
achieve the desired final
formulation, and mixed for approximately 5 minutes. The drug solution was
transferred to a
volume-dispensing device set to deliver 1.2 mL per vial. Under nitrogen
pressure, the solution was
filtered through two 0.2 um polyvinylidene fluoride filters in series before
dispensing. The vials
were capped with Teflon-coated, butyl-rubber stoppers and crimp sealed.
Materials used in the product vials are listed below.

Example Z. BrEA formulation 2. A formulation containing 100 mg/mL of HrEA, 10%
w/w, in benzyl benzoate (USP) 30.4% w/w, polyethylene glycol 300 (NF) 30.7%
w/w, propylene
glycol (USP), qs, about 28% w/w and benzyl alcohol (NF) 1.9% w/w, hereafter
"formulation 2",
was prepared as follows. A desired amount of BrEA ( I .0 kg) was suspended in
PEG 300 (about
3.0 L) in a compounding vessel and mixed for at least ~ minutes at room
temperature t0 form a
smooth creamy liquid. The needed amount of propylene glycol (about 1.5 L) was
then added and
mixing was continued for at least S minutes to form a uniform suspension.
Benzyl benzoate (about
3.0 L) was then added and the vessel contents were mixed for about Sminutes to
form a translucent
suspension. Benzyi alcohol (about 200 mL) was then added and the mixing was
continued for
about 5 minutes to form a clear, colorless solution. Propylene glycol was then
added to achieve the
desired final formulation volume (about 1.5 L) and mixing was continued for
about 5 minutes. The
drug solution was transferred to a volume-dispensing device, which was set to
deliver 1.2 mL per
vial (2 mL, glass, type 1 amber vials). The formulation was filtered under
nitrogen pressure (about
3 atm) through two 0.2 wm polyvinylidine fluoride filters in series. The vials
were capped using
Teflon-coated, butyl rubber stoppers and then crimp sealed essentially as
described in example 1.
The vials were stored in the dark at reduced temperature (about 2-8oC).
Example 3. In vitro testine. For in vitro antimalarial testing, micro-titer
plates were
used. The concentration of drugs were prepared as pMol/well according to WHO
standard
procedures (WHO, 1990). The test compound was dissolved in 1 S% DMSO in
sterile RPM 11640.
Both chloroquine sensitive (WS/97) and resistant (MN/97) isolates were used
throughout the
experiments.
A. Schizont inhibition assay: The micro-titer plates were predosed with
various
concentrations of the test compound. 50 ~L of parasitised erythrocyte
suspension in RPMI-1640
(0.2 mL erythrocyte + 0.3 mL serum + 4-5 ml RPMI-1640) were dispensed in
microtiter wells that
contained various concentrations of drug. Triplicate readings were made for
each concentration.
B. 3H-Hvnoxanthine incorporation assay: The testing was carried out according
to the
procedure of Desjardins et al.. 1979. After 30 hr culture at 37 degrees C, the
same microtiter plates
from schizont inhibition assays with another triplicate wells were pulsed with
3H-hypoxanthine for

Example 4. Four-day in vivo test protocol for P. berghei. The 4-day
suppressive test
has been widely used since it can be performed with a 1 -week period. The test
consists of the
inoculation of parasitised erythrocytes on Monday, the first day of the
experiment (DO), followed
by an injection of the test compound, which is repeatedly administered on D+1,
D+2, D+3. On
D+4 (Friday), blood films are taken and antimalarial activity is assessed
either by calculating

parasitaemias, or by scoring parasite numbers on a predetermined scale (i.e.,
1-5). Peters (1970)
described a basic procedure using this 4-day test.
PROTOCOL
1 . 5 female TO mice per test group.
2. Parasites (P. berghei HP15 ANKA) were collected by cardiac puncture in a
heparinised syringe from a donor mouse harboring a 30+% parasitaemia.
3. Blood was diluted with diluting agent (50% HIFCS+50% sterile PBS) to a
final
concentration of 1% parasitaemia or iX107 infected erythrocytes per 0.2 mL
infecting
suspension.
4. Each mouse was inoculated intravenously, producing a more uniform infection
rate than an
intraperitoneal administration of parasites.
5. Test compounds were prepared at doses of 100 mg/kg in (16.7% DMSO + 83.3%
Celacol).
6. Test compounds were administered intraperitoneally 2 hours after parasite
inoculation.
7. The compounds were administered once a day starting on D0, and continued on
D+1, D+2 and D+3.
8. Blood films were made from tail blood on D+4, fixed with l00% methanol and
stained with 10% Giemsa.
9. Parasitaemias were scored on a scale of 0-S, where a 5 would be equal to
the
control.
EXPERIMENTAL PROTOCOL:
5 female mice/group (strain TO) were used and an inoculum consisting of 1
parasitaemia or 1x107 parasites/mL, 0.2 mL/mouse was delivered by intravenous
injection. Drug
administration commenced 2 hours after inoculation on Day 1 and continued for
3 days. Blood
films from all 20 mice were made on Day 5 and parasitaemias were assessed. The
results are
shown below.

Example 6. Mouse in vitro and in vivo study. In the in vitro protocol the
parasite
(Plasmodium falciparum, chloroquine sensitive strain WT and chloroquine
resistant strain Dd2)
level is adjusted to I% and the hemocrit is adjusted 7% with medium. Using a
96 well plate, 50
ItL of parasite and 100 IzL of drug mixed with media are added to each well
and the procedure is
done in triplicate. The plate is placed in a chamber containing a
physiological gas mixture and
incubated at 37oC. The media/drug mixture is changed at 24, 48 and 72 hours.
On day S (96
hours) slides of each well are made, stained with Gemsia and 500 red blood
cells are counted for
each slide. The triplicates are averaged and data are reported in percent
inhibition.
In the in vivo protocol, Lewis rats weighing 80-85 grams were given a
standardized IP
injection of parasite (Plasmodium berghei). Rats were then intravenously
injected 2 hours later
with one of the treatments described in the table below, returned to their
housing, fed standard lab
chow and allowed free access to water. Animals were weighed and treated again
24, 48, and 72
hours after the first treatment and again returned to their housing and they
were allowed free access
to food and water. The animals were weighed again and then bled using a 26-
gauge needle on day
5, 1 1 and 28 post inoculation. Hemocrits were measured and blood smears are
prepared for each
91

rat. The blood smears were then stained using Gemsia and the level of
parasitemia (defined as the
percent of red cells with parasites) were determined. Animals were again
returned to their housing
and observed twice daily for evidence of progressive disease, defined as
listlessness and or adverse
drug reaction, which is defined as a loss of 20% of original body weight, for
a total of 28 days. If
either progressive disease or drug reaction is noted, the animals are
euthanized.

Example 7. Human clinical study. Response to drug treatment was graded as per
World
Health Organization criteria (WHO 1973). Evaluation of therapeutic response
was determined
5 using the parasitic and fever clearance times. Parasite clearance was
expressed as three indices; the
time for the parasite count to fall by 50% of the pre-treatment (baseline)
value (PC50); to fall by 90
of the baseline value (PC9p) and to fall below the level of microscopic
detection (parasite
clearance time PCT) (White and Krishna 1989; White et al. 1992). The fever
clearance time was
defined as the time from drug administration till the oral or rectal
temperature fell to or below
10 37.2o C and remained so for at least 48 h.
Venous blood (SmL) was obtained from two patients before treatment and at 4,
6, 8, 12,
18, 20, 24, 30 and 36 h after treatment or at 4 or 6-hourly intervals after
treatment until there was
complete clearance of peripheral parasitemia. Blood was collected aseptically
and transferred to 10
mL syringes containing 2 mL of acid citrate dextrose (ACD) for in vitro
culture. Prior to
incubation, the plasma was separated from the red blood cells and the red
blood cells were washed
twice. Parasites were cultured by modification of standard in vitro culture
techniques (Trager and
Jensen 1976; Oduola et at. 1992). Samples were dispensed into sterile
centrifuge cubes within 10
min of collection and spun down. The supernatant plasma was stored while the
packed cells were
washed twice with culture medium (washing medium, RPMI 1640 medium, containing
25 mM
HEPES buffer and 25 mmol/L NaOH). The huffy coat was removed by vacuum
aspiration. A 1:10
fold dilution was done for each blood sample with complete washing medium [CMP
(washing
medium supplemented with 10 % human plasma)]. One milliliter each of the
sample was

transferred into 2 wells of a 24 well micro culture plate. Cultures were
incubated at 37 degrees C in
an atmosphere of S% C02, S% 02 and 90% N2 premixed gas. The culture medium was
changed
daily and thin blood smears were prepared for microscopy at 24 and 48 h after
the culture has been
set up. The culture samples were diluted with unparasitized washed type A Rh-
positive red blood
S cells if the proportion of parasitized red blood cells was more than 2%.
Microscoov. During the in vivo study, thin and thick blood films were fixed
with
dehydrated methanol (100%) and heat, respectively, were stained with 10%
Giemsa for 20 min.
Parasitemia was quantified in thin films by counting 2000 red blood cells in
clear contiguous fields
and finding the proportion that was parasitized. In thick films, parasitemia
was quantified by
counting parasites against leukocytes. A film was declared negative if no
parasites were found after
examination of 200 microscope fields of a thick smear. During in vitro and ex
vivo study,
pretreatment thin and thick smears were, graded for ring stages by the method
of Jiang as modified
by Li et al. (Jiang et al, 1982; Silamut and White 1993; Li et al, 1994).
Approximately 5000
erythrocytes were counted in clear contiguous fields 24 and 48 h after
incubation of blood obtained
at each time point and graded for maturity into tiny rings, small rings, large
rings, pigmented
trophozoites and schizonts. Functional viability was estimated as the
percentage of asexual ring
forms capable of maturing to pigmented trophozoites or schizonts after 24-48 h
of in vitro culture
(Watkins et al. 1993).
Calculations of parameters. The Patients presented with acute symptomatic
severe
non-cerebral pure P. Falciparum malaria, they had oral fluid intolerance and
had body temperatures
greater than 39 degrees C, greater than 5000 parasites per micro liter of
blood and asexual
parasitemia and they had a negative urine test for antimalarial drugs. They
were administered 2S
mL intravenously every four hours with bromine epiandrosterone (16a,-
bromoepiandrosterone)
suspended in 45% beta cyctodextrin in saline at a concentration of 25 mg/mL.
This regimen was
2S continued for four days. Parasitemia quantification and clinical
examination were done once every
6 hours for the first 72 hours, followed by daily assessment of the parameters
up to day 7 ( 168 hrs)
and thereafter on day 14.
The blood films were Giemsa-stained and parasitemia quantification was done in
thick
films by counting 2000 parasites against leukocytes, and the thin films by
finding the proportion of
infected red blood cells. Response to drug treatment was graded according to
WHO criteria.
Evaluation of therapeutic response was done using the parasitic and fever
clearance times. Parasite
clearance was expressed as three indices: The time for the parasite count to
fall by SO% of the
pre-treatment (baseline) value (PC60); to fall by 90% of the baseline value
(PC90); and to fall
below the level of microscopic detection (parasite clearance time) PCT.

Example 8. Cellular studies in vitro. The effect of Bromine
Epiandrosterone~EPI, 16a,-
bromoepiandrosterone) on pentosephosphate shunt (PPS) activity in normal human
RBC was
examined using whole cells. Since glucose-6-phosphate dehydrogenase ("G6PD")
is the limiting
enzyme of the PPS, PPS flux measurement is considered to better reflect G6PD
activity in the
whole cell compared to G6PD activity measurement in a cell lysate. G6PD
activity measured in a
cell lysate is typically about 1100-fold higher than the PPS flux in whole
resting unstimulated RBC
(G6PD activity in cell lysate: 165; PPS flux 0.142 micromoles/hour/ml RBC).
PPS flux and G6PD
activity in the whole RBC depends on a number of factors (the concentration of
NADPH, NAD,
and ATP, and intracellular pH), which are kept constant if the measurement is
performed in the
lysate and may vary in the whole RBC. Levels of G6PD activity in cells is
considerably above
normal basal needs and inhibition of overall G6PD activity might have no or
minor consequence
on PPS flux in the whole cell. For example, RBC with the Mediterranean G6PD
mutant with about
1-3 percent residual activity compared with normal individuals have no
impairment in basal PPS
flux, but show impaired flux when flux through PPS is stimulated by methylene
blue addition. A
series of experiments were perfromed using varying amounts of EPI and PPS flux
was measured in
unstimulated basal RBC and in methylene-blue (MB)-stimulated RBC.
The data below shows PPS flux (micromoles/hour/ml RBC) in basal unstimulated,
and
MB-stimulated normal RBC. Different concentrations of EPI (0.3, 3.5 and 7
micromolar, final)
were supplemented to suspensions of washed RBC suspended in RPMI, pH 7.4 at
10% hematocrit,
whereby PPS flux was immediately measured without further incubation and
without further
washings. A minor inhibition of MB-stimulated PPS flux was observed with EPI
at 7 uM.

Parasitemias were determined by standard methods (microscopic inspection of at
least S00
cells, stained with Diff QuickTM (Baxter). Parasites were cultured under
standard conditions in
RPMI-1640 supplemented with Hepes/Glucose (10 mM), glutamine (0.3 g/liter) and
10% human
plasma. The hematocrit was 1 %.
Example 10. Stimulation of phagocytosis. The capacity of EPI (l6oc-bromo-
epiandrosterone) to influence phagocytosis of Plasmodium parasite infected RBC
is examined
using adherent human monocytes. The parasitemia level is about 8-10% and human
monocytes are
obtained from huffy coats from blood as follows. Peripheral blood mononuclear
cells are
separated from freshly collected platelet-poor huffy coats discarded from
blood samples of healthy
adult donors of both sexes. Separated cells are washed once with Juke-warm PBS
supplemented
with 10 mM glucose (PBS-G) and resuspended at 5 x 106 cells/mL in ice-cold
RPMI 1640 medium
supplemented with 23 mM NaHC03 and 25 mM Hepes, pH 7.4 (RMBH). Dynabeads M450
Pan B
and Pan T (Dynal) are added to cells in a 4:1 ratio for 20 min at 4oC. B-
lymphocytes and
T-lymphocytes are removed as specified by the manufacturer. The remaining
monocytes are
washed 2 times in RMBH, resuspended in AIM V cell culture medium (Gibco) at 1
x 106 cell/mL.
The monocyte layer is collected, washed with PBS-G at 37oC and resuspended in
AIM V medium
at 1 x 106 cells/mL. Purified cells are >90% monocytes as assessed by CD14
expression.

Phagocytosis of opsonized parasitized RBC (PE) is determined as follows.
Phagocytosis
of fresh-serum opsonized PE is initiated by mixing 10 PE/monocyte. Suspensions
are briefly
centrifuged ( 150 x g for 5 sec at room temperature) to improve contact
between PE and monocytes.
To avoid attachement of monocytes after centrifugation and during the whole
incubation period,
cells are kept in
- suspension at S x 106 cells/5 mL AIM V medium in 6 cm diameter teflon bottom
dishes
(Heraeus) in a humidified incubator (95% air, 5% C02) at 37oC. On average, at
least 90%
of the monocytes phagocytose PE, as assessed by microscopic inspection.
Control cells are kept
under similar, conditions without phagocytosis. Quantitative assessment of
phagocytosis is
performed by a previously described bioluminescence method (E. Schwarzer, et
al., Br. J.
Haematol. 1994 88:740-745).
Erythrocyte treatments and parasite cultures are as follows. Fresh blood
(Ith+)~ts used to
isolate erythrocytes (RBC). Washed RBC are infected with schizont/trophozoite
parasite stages
(Palo Alto strain, mycoplasma-free). Stage specific parasites are isolated by
the Percoll-mannitol
method. Briefly, normal schizont-stage parasitized E (SPE) separated on
Percoll-mannitol
gradient (parasitemia > 95% SPE) are mixed with E suspended in growth medium
(RPMI 1640
medium containing 25 mmol/L Hepes, 20 mmol/L glucose, 2 mmol/L glutamine, 24
mmoUL
NaHC03, 32 mg/L gentamicin and 10% AB or A human serum, pH 7.30) to start
synchronous
cultures at selected hematocrit values. The inoculum parasitemia is adjusted
to 20% normal SPE
for isolation of ring parasitized ItBC (ItPE) and to 5% normal SPE for
isolation of
trophozoite-stage parasitized E (TPE). At 14-18 hours after inoculum parasites
are at ring-stage in
the first cycle; at 34-33 hours, parasites are at trophozoite-stage in the
first cycle; and at 40-44
hours after inoculum parasites are at schizont-stage in the first cycle. RPE,
TPE and SPE are
separated on Percoll-mannitol gradients. The parasitemia is usually 8-10% RPE,
and >95% TPE.
Nonparasitized and parasitized RBC are counted electronically. To assess total
parasitemia and
relative contribution of RPE, TPE and SPE, slides are prepared from cultures
at indicated times,
stained with Diff QuikTM parasite stain and 400-1000 cells are examined
microscopically.
The effect or EPI in parasitized RBC is examined using various concentrations
of EPI, e.g.,
0.5 ~M, I p,M, 10 p.M, 25 p.M and 50 ~M. Trophozoite-parasitized RBC, schizont-
parasitized
RBC or ring-parasitized RBC are examined as described.
Example 11. Human clinical trial. The clinical trial protocol that
incorporates about 15-
20 patients is established. For a phase I or I/II trial, the patients are
mildly infected with one or
more Plasmodium parasites and they are mildly symptomatic (less than about 8-
10% parasitemia
of RBC). Before treatment, the patients are optionally tested for infection
with HIV, HCV, TB,
and Cryptosporidium. Patients with one or morc co-infections are given
standard care for the

coinfection. The patients are hospitalized for treatment for one week. Two or
more dose groups,
e.g., 25, 50 or 100 mg/day of l6oc-bromoepiandrosterone (BrEA), or an ester
thereof, administered
parenterally, e.g., by intramuscular or intravenous injection, on 3, 4 or S
days of the week when
patients are dosed. Dosing is on consecutive days or on an intermittent
schedule, e.g., 2, 3 or 4
doses with one dose administrered every other day. The formulation containing
BrEA is as
' described herein, e.g., the formulation of example 1 or 2. At day S-7, if
less than about 50%
reduction in parasitemia is observed, the patients are given standard care for
malaria (mefloquine).
During the week of treatment and for 1, 2 3, or more weeks theerafter, blood
samples are taken
periodically for evaluation of parasitemia, pharmacokinetics, plasma cytokines
(e.g., IL-2, IL-4,
IL-10, IGF1, yIFN, GM-CSF), and intracellular cytokines (e.g., IL-2, IL-4, IL-
10, IGFI, yIFN,
GM-CSF). The patients are optionally treated again at about 2 to 12 weeks
after the initial dosing,
using the same or a similar protocol as that used in the initial dosing
protocol.
To the extent not already indicated, it will be understood by those of
ordinary skill in the
art that any one of the various specific embodiments herein described and
illustrated may be
further modified to incorporate features shown in other of the specific
embodiments.
The foregoing detailed description has been provided for a better
understanding of the
invention only and no unnecessary limitation should be understood therefrom as
some
modifications will be apparent to those skilled in the art without deviating
from the spirit and scope
of the appended claims.
