Cell line producing analgesic co~pounds for treating pain
Field of the Invention
The present invention relates to a cell line
useful for the treatment of pain. More particularly,
the cell line of this invention has been genetically
engineered to produce at least one analgesic compound
from each of the groups consisting of endorphins,
enkephalins, and catecholamines.
o Background of the Invention
Pain is a common symptom of disease. The
superficial dorsal horn of the spinal cord, where
primary afferent fibers carrying nociceptive
information terminate, contains enkephalinergic
interneurons and high densities of opiate receptors.
In addition, there is a dense concentration of
noradrenergic fibers in the superficial laminae of the
spinal cord.
Acute pain arises in response to acute
noxious stimuli. Chronic pain is predominantly due to
neuropathies of central or peripheral origin. This
~ ul~ SNEEr (RULE ~6)
CA 02223246 1997-12-02
WO ~f'4C35~ PCT~US96/09629
neuropathic pain is the result of aberrant
somatosensory processing that can result in increased
sensitivity to a painful stimulus (hyperalgesia) and
pain associated with a stimulus that does not usually
provoke pain (allodynia).
Intrathecal injection of morphine into the
spinal subarachnoid space produces potent analgesia.
Similarly, intrathecal administration of norepinephrine
or noradrenergic agonists also produces analgesia.
o See, e.g., Sagen et al., Proc. Natl. Acad. Sci. USA,
83, pp. 7522-26 (1986).
Co-administration of subeffective doses of
opiates, such as enkephalins, and catecholamines, such
as norepinephrine, may synergize to produce analgesia.
Ibi~. Chromaffin cells in the adrenal medulla produce
and release several neuroactive substances including
norepinephrine, epinephrine, met-enkephalin, leu-
enkephalin, neuropeptide Y, vasoactive intestinal
polypeptide, somatostatin, neurotensin, cholecystokinin
and calcitonin gene-related peptide. See, e.g., Sagen
et al., Proc. Natl. Acad. Sci. USA, 83, pp. 7522-26
(1986); Sagen et al., Joux. Neurochem., 56, pp. 623-27
(1991).
Because chromaffin cells produce both opioid
peptides and catecholamines, one approach to reduction
of nociceptive response or pain sensitivity has
investigated transplanting adrenal medullary tissue, as
well as isolated adrenal chromaffin cells, directly
into CNS pain modulatory regions, in attempts to
provide analgesia. See, e.g., Sagen et al., 1~ in
Research, 384, pp. 189-94 (1986); Vaguero et al.,
Neuroreport, 2, pp. lg9-51 (1991); Ginzberg and
SE~p~Ul~26)

Seltzer, Brain Research, 523, pp. 147-50 (1990); Sagen
et al., ~in, 42. pp. 69-79 (1990).
Attempts to produce analgesic have been made
using both allogeneic and xenogeneic chromaffin tissue
s or cells transplants. Allograft tissue is in limited
supply, and is not readily available, particularly for
in human pain treatment programs. In addition,
allogeneic human tissue carries the risk of pathogenic
contamination. See e.g., Hama and Sagen, Brain
o Research, 651, pp. 183-93 (1994).
Xenogeneic donors may provide large
quantities of material that can be readily obtained.
For this reason, bovine adrenal tissue has been used.
See, e.g., Hama and Sagen, Brain Rese~rch, 651,
pp. 183-93 ~1994).
However, potentially serious host
consequences, as well as ultimate graft rejection, are
inherent problems in transplantation between disparate
species. Complete graft rejection of whole or
dissociated tissue may occur even in the CNS, normally
thought to be immunologically privileged, due to
presence of highly antigenic cells in the xenografts,
particularly endothelial cells. In addition, the donor
tissue must be carefully screened to avoid introduction
of viral contaminants, or other pathogens, to the host.
To overcome graft rejection, immunosuppression is
required typically using cyclosporine A.
Some reduction in pain sensitivity has been
reported resulting from these transplants, particularly
for the reduction of low intensity chronic pain. In
most reports, significant differences between control
and transplanted animals were noted only after nicotine

administration to stimulate opioid peptide production.
However, there have been some reports that analgesia
has been observed in a rat chronic pain model from
basal level activity of chromaffin tissue allografts.
See, e.g., Vaquero et al., NeuroReport, 2, pp. 149-51
(1991) and Hama and Sagen, ~rain Rese~rch, 651, pp.
183-93 (1994).
Bovine adrenal chromaffin cells have been
encapsulated to form a bioartificial organ ("BAO") for
o implantation into rats for the treatment of acute and
chronic pain. See, e.g., Sagen et al., J. Neurosci.,
13, pp. 2415-23 (1993) and Hama et al., 7th Wo~ld
Con~ress P~in, Abstract 982, Paris France (1993).
Initial trials in human subject have been conducted
using encapsulated bovine chromaffin cells. See,
Aebischer et al., Tr~nsplantation, 58, pp. 1275-77
(1994).
There have also been attempts to induce
antinociception using other cells, e.g., AtT-20 cells.
AtT-20 cells were originally derived from a mouse
anterior pituitary tumor. These cells synthesize and
secrete ~-endorphin. See, e.g., Wu et al., J. Neur~l
Tr~nspl. & Pl~sticity, 5, pp. 15-26 (1993).
AtT-20/hENK cells are AtT-20 cells that have been
genetically engineered to carry the entire human pro-
enkephalin A gene (i.e. containing 6 met-enkephalin
sequences and one leu-enkephalin sequence) with 200
bases of 5'-flanking sequence and 2.66 kilobases of 3'-
flanking sequence. See Wu et al., supra, Comb et al.,
F~MRO J , 4, pp. 3115-22 (1985).
Wu et al., J. Neural Transpl. ~ Plasticity,
5, pp. 15-26 (1993) refers to rat hosts transplanted

with AtT-20 or AtT-20JhENK cells. Unstimulated AtT-
20/hENK cells produced more antinociception (tail flick
test) than produced by AtT-20 implants. In contrast,
isoproterenol stimulation produced more antinociception
with AtT-20 cells than with AtT-20/hENK cells. Ibid.
In mice hosts, AtT-20 or AtT-20/hENK implants
did not affect basal response to thermal nociceptive
stimuli. Mice receiving AtT-20 implants developed
tolerance to ~-endorphin and a u-opioid agonist
lo (DAMGO). Mice receiving AtT-20/hENK implants developed
tolerance to an ~-opioid agonist (DPDPE). In ~esponse
to repeated doses of an u opiate agonist, mice
receiving AtT-20/hENK implants developed less tolerance
compared to mice receiving AtT-20 cells or controls.
The antinociceptive effect of isoproterenol
treatment appeared equal in mice receiving AtT-20 or
AtT-20/hENK cell implants. See, Wu et al., J.
Neuroscience, 14, pp. 4806-14 (1994). Wu et al.
speculated that one reason for the absence of
additional antinociception in mice implanted with
enkephalin producing AtT-20/hENK cells may be due to
lack of sensitivity of the behavioral assays. Another
possible reason was that met-enkephalin's known
antagonist effect on morphine induced antinociception
offset the potentiating effect of the single
leu-enkephalin, particularly since there are 6 met-
enkephalin sequences for each leu-enkephalin sequence
in pro-enkephalin A.

Sllmm~ry of the Invention
The present invention provides a cell line
that has been genetically engineered to produce at
least one analgesic compound from each of the groups
s consisting of endorphins, enkephalins, and
catecholamines. The cell line may be used in the
treatment of pain.
There are advantages to using a cell line
over the use of primary cells. Expensive and time
o consuming testing to ensure safety and performance
criteria for cells must be performed for individual
isolations of primary cells. Less testing is required
of a cell bank. There is no need to isolate primary
cells. Output of the desired analgesics may be more
stable since the performance of primary cells may be
dependent on the age, sex, health or hormonal status of
the donor animal. It is also possible to achieve
higher output of the desired products, as well as to
engineer specifically modified peptides into the cell
line. This permits delivery of multiple analgesics
simultaneously. Expression of one or more of the
analgesics can be regulated (by using a regulatable
promoter to drive expression). In addition, for
safety, a "suicide" gene can be incorporated into the
cell line. Further, for encapsulation purposes
proliferating cells have the advantage that they divide
to replace dying or dead cells.

Det~ile~ DescriDtion of the Invention
In order that this invention may be more
fully understood, the following detailed description is
set forth.
Any suitable cell may be transformed with the
recombinant DNA molecules of this invention. Among the
contemplated cells are chromaffin cells, including
conditionally immortalized cnromaffin cells such as
those described in WO 96/02646, Neuro-2A, PC12, PCI2a,
o SK-N-MC, AtT-20, and RIN cells including RINa and RINb.
Preferably the cell has endogenous prohormone
convertases and/or dopa decarboxylases.
SK-N-MC cells, a neuroepithelioma cell line,
co-expresses several neuropeptides, including
15 enkephalin, cholecystokinin and gastrin-releasing
peptide. See, e.g., Verbeeck et al., J. Biol. Chem.,
265, pp. 18087-090 (1990). The pro-enkephalin A gene
has been expressed in SK-N-MC cells. See, e.g.,
Folkesson et al., Mol. Brain Res., 3, pp. 147-54
20 (1988). We prefer AtT-20 and RIN cells, most
preferably RIN cells.
RIN cells are a pancreatic endocrine cell
line derived from rat. See, e.g., Horellou et al.,
J. Physiol., 85, pp. 158-70 (1991). RIN cells are
25 known to endogenously produce GABA and B-endorphin.
Some of the characteristics of various
contemplated cells are shown in Table 1.

The primary delivery products include at
least one each of an endorphin, an enkephalin and a
20 catecholamine.
Enkephalins and endorphins are endogenous
opioid peptides in humans. These opioid peptides
comprise approximately 15 compounds ranging from 5 to
31 amino acids. These compounds bind to and act at
25 least in part via the same ~ opioid receptor as
morphine, but are chemically unrelated to morphine. In
addition, these compounds stimulate other opiate
receptors. Yaksh and Malmberg, Textbook of Pain, 3rd
Ed. (Eds. P. Wall and R. Melzack), "Central
Pharmacology of Nociceptive Transmission," pp. 165-200,
1994 (New York).
The opioid peptides have common chemical
properties, but are synthesized in different pathways.

~ -endorphin, the most abundant endorphin, is
synthesized as part of a larger precursor molecule,
pro-opiomelanocortin t"POMC"). The POMC molecule
contains the full sequence of adrenocorticotrophic
s hormone ("ACTH"), a-melanocyte-stimulating hormone
("a-MSH"), ~-MSH, and ~-lipotropin. The POMC precursor
molecule also has the potential to generate other
endorphins, including a-endorphin and gamma-endorphin.
Processing of the POMC precursor occurs differently
within various tissues according to the localization of
cleavage enzymes, such as prohormone convertase's,
within those tissues.
In the pituitary, POMC is cleaved to produce
ACTH and ~-endorphin, and the ACTH is not further
processed. In contrast, in the hypothalamus, ACTH is
converted to ~-MSH. While different cell types may
synthesize the same primary gene product, the final
profile of hormone secretion may differ widely.
This invention contemplates use of a DNA
sequence encoding any suitable endorphin that has
analgesic activity. In addition, analogs or fragments
of these endorphins that have analgesic activity are
also contemplated. Thus the endorphin to be produced
by the cells of this invention may be characterized by
amino acid insertions, deletions, substitutions and
modifications at one or more sites in the naturally
occurring amino acid se~uence of the desired endorphin.
We prefer conservative modifications and substitutions
(i.e., those having a minimal effect on the secondary
or tertiary structure of the endorphin and on the
analgesic properties of the endorphin). Such
conservative substitutions include those described by

~1978) and by Argos, ~m~o J., 3, pp. 779-85 (1989).
- Techniques for generating such variants of
naturally occurring endorphins are well known. For
example, codons in the DNA sequence encoding the wild
type endorphin may be altered by site specific
mutagenesis.
This invention contemplates using a DNA
sequence encoding the entire POMC precursor molecule.
This embodiment takes advantage of the host cell's
cleavage enzymes (i.e., Prohormone convertase 2) to
generate a suite of endorphins, some or all of which
may have analgesic properties.
This invention also contemplates use of DN~
fragments of the POMC gene that encode a particular
desired endorphin.
The DNA and amino acid sequence of POMC are
well known. Cochet et al., Nature, 297, pp. 335-9
(1982); Takahashi et al., Nucl. Acids Res., 11,
pp. 6847-58 (1983).
We prefer a DNA sequence encoding POMC in
which the ACTH coding region has been deleted. The
preferred endorphin encoded by this construct is
~-endorphin.
Some enkephalins are synthesized in the
adrenal glands as part of a large protein, pro-
enkephalin A, that contains six repeats of the Met-
enkephalin sequence and one Leu-enkephalin structure.
Met-enkephalin, as well as Met-enkephalin-Arg-Phe and
Met-enkephalin-Arg-Gly-Leu have significant
antinociceptive activity. See, e.g., Sagen et al.,
Brain Res., 502, pp. 1-10 (1989).

Other enkephalins, i.e., dynorphins and neo-
endorphins are derived from a distinct molecule, pro-
enkephalin B. Additional "cryptic" peptides are also
encoded within the structure of these precursor
s proteins, and may be released by "pro-hormone-type"
cleavage. See, e.g., Harrison's "Principles Of
Internal Medicine", 12th Edition, pp. 1168-69 (1991).
This invention contemplates use of a DNA
sequence encoding any suitable enkephalin that has
analgesic activity. Analogs and active fragments that
have analgesic properties are also contemplated. Such
analogs or fragments may thus have amino acid
insertions, deletions, substitutions at one or more
sites in the naturally occurring amino acid sequence.
Such variants may be generated as described above.
This invention contemplates use of a DNA
sequence encoding a desired enkephalin in its "mature"
form. In addition, this invention contemplates using a
DNA sequence encoding the entire pro-enkephalin A
precursor, or the entire pro-enkephalin B precursor.
Further, we also contemplate using DNA encoding a
fusion, or fragment of these sequences, that upon
expression yields one or more enkephalin-like molecules
that have analgesic properties.
We prefer use of a DNA sequence encoding the
entire pro--enkephalin A precursor molecule. The DNA
and amino acid sequence of pro-enkephalin A are well
known. Folkesson, supra. This embodiment takes
advantage of the host cell's cleavage enzymes, such as
prohormone convertase, to generate a suite of
enkephalins, some or all of which may have analgesic

properties. The pre~erred enkephalin encoded by thisconstruct is Met-enkephalin.
There are three naturally occurring
catecholamines which function as neurotransmitters in
the central nervous system; norepinephrine ("NE"),
epinephrine ("E"), and dopamine. NE is associated with
postganglionic sympathetic nerve endings. NE exerts
its effects locally in the immediate vicinity of its
release.
Catecholamines are synthesized from the amino
acid tyrosine, which is sequentially hydroxylated to
form dihydroxyphenylalanine (dopa), decarboxylated to
form dopamine, and then hydroxylated on the beta
position of the side chain by dopamine beta hydroxylase
to form NE. Harrison's, supra, pp. 380. NE is
N-methylated to E by phenylethanolamine-N
methyltransferase ("PNMT").
Hydroxylation of tyrosine by tyrosine
hydroxylase ("TH") is the rate limiting step in NE
synthesis. Regulation of dopa and NE synthesis in the
adrenal medulla may be accomplished by changes in the
amount and the activity of TH.
In addition, regulation of synthesis of E
from NE may occur by changes in the amount and the
2s activity of phenylethanolamine-N-methyltransferase
("PNMT"). PNMT is inducible by glucocorticoids from
the adrenal cortex. Ibid.
Catecholamines are maintained in high
concentration in adrenal medullary chromaffin tissue,
mostly as E. Opioid peptides are also stored in the
adrenal gland.

NE and E have similar affinities at ~2
receptors and therefore both potentially contribute to
analgesia. Bylund, FA~R J., 6, PP. 832-39 (1992).
The enkephalin peptides that predo~;n~ntly include met-
s enkephalin selectively activate delta (~) opioid
receptors. Reisine and Bell, Trends Neurosci., 16,
pp. 506-10 (1993). Activation of a2 adrenergic and o
opioid receptors in the spinal cord each result in
antinociception and are potentially synergistic. Yaksh
o and Malmberg, Progress in Pain Research and Management,
Vol. 1, Ed. Fields and Lisbeskind, IASP Press, Seattle,
pp. 141-71 (1994). Activation of ~ versus (~) opioid
receptors in experimental animals results in fewer
adverse side effects including constipation and
addiction liability (Lee et al., J. Pharmacol. Exp.
Ther., 267, pp. 883-87 (1993). The combined delivery
of different opioidergic and adrenergic agents may
decrease the magnitude of tolerance that develops to a
single agent and lead to sustained pain relief. Yaksh
20 and Reddy, Anesthesiol., 54, pp. 451-67 (1981).
This invention contemplates use of a DNA
sequence encoding catecholamine biosynthetic enzymes or
analogs or fragments thereof to obtain catecholamines
that have analgesic properties. The preferred
2s catecholamines in this invention are NE and E.
In one embodiment, the host cell is
transformed with the genes necessary to accomplish
production of NE or E, as desired. The selection Oc
heterologous gene sequences required depends upon the
complement of catecholamïne synthesizing enzymes
normally occurring in the host cell. For example, RIN
cells, and AtT-20 cells lack tyrosine hydroxylase

~ ("TH") and dopamine beta hydroxylase ("DBH"). However,
RIN and AtT-20 cells contain endogenous dopa
decarboxylase ("DDC"). If the desired catecholamine is
E, then the gene encoding PNMT is also required. The
gene encoding PNMT is known. Baetge et al., Proc.
N~t'l Ac~. Sci., 83, pp. 5455-58 (1986).
The gene encoding TH is known. See, e.g.,
United States patent 5,300,436, incorporated herein by
reference. Modified TH variants are also known.
o United States patent 5,300,436. In addition, truncated
versions of TH that contain the necessary C-terminal
catalytic domains are also known. See, e.g., Daubner
et al., Protein Science, 2, pp. 1452-60 (1993).
AtT-20 cells have been transformed with wild
type TH, as well as various TH muteins. See, e.g., Wu
et al., J. Biol. Chem., 267, pp. 25754-758 (1992).
The sequence of the DBH gene is also well
known. See, e.g., Lamoroux et al., EMBO J., 6,
pp. 3931-37 (1987).
It will be appreciated that in addition to
the preferred DNA sequences described herein, there
will be many degenerate DNA sequences that code for the
desired analgesics.
Secondary compounds with potential analgesic
action may also be produced by the cells of this
invention. Such compounds include galanin and
somatostatin. In addition, neuropeptide Y, neurotensin
and cholecystokinin may be produced by the transformed
cells of this invention. The cells of this invention
may normally produce some or all of these compounds, or
may be genetically engineered to do so using standard
techniques.

Standard methods may be used to obtain or
synthesize the genes encoding the analgesic compounds
to be produced by the cells of this invention.
For example, the complete amino acid sequence
of the desired compound may be used to construct a
back-translated gene. A DNA oligomer containing a
nucleotide sequence coding for the desired analgesic
compound may be synthesized. For example, several
small oligonucleotides coding for portions of each
desired polypeptide may be synthesized and then
ligated. The individual oligonucleotides typically
contain 5' or 3' overhangs for assembly.
The DNA sequence encoding each desired
analgesic compound, may or may not also include DNA
sequences that encode a signal sequence. Such signal
sequence, if present, should be one recognized by the
cell chosen for expression of the analgesic compound.
It may be prokaryotic, eukaryotic or a combination of
the two. It may also be the signal sequence of the
native compound. It generally is preferred that a
signal sequence be encoded and most preferably that the
native signal sequence be used.
Once assembled, the DNA sequences encoding
the desired compounds will be inserted into one or more
expression vectors and operatively linked to expression
control sequences appropriate for expression in the
desired transformed cell.
Proper assembly may be confirmed by
nucleotide sequencing, restriction mapping, and
expression of a biologically active polypeptide in the
transformed cell. As is well known in the art, in
order to obtain high expression levels of a transfected

gene in a host, the gene must be operatively linked to
transcriptional and translational expression control
sequences that are functional in the chosen expression
cell.
The choice of expression control sequence and
expression vector will depend upon the choice of cell.
A wide variety of expression host/vector combinations
may be employed. Useful expression vectors for
eukaryotic hosts, include, for example, vectors
o comprising expression control sequences from SV40/
bovine papilloma virus, adenovirus and cytomegalovirus.
We prefer pcDNA3, pCEP4, pZeoSV (InVitrogen,
San Diego) and pNUT.
Any of a wide variety of expression control
sequences may be used in these vectors. Such useful
expression control sequences include the expression
control sequences associated with structural genes of
the foregoing expression vectors. Examples of useful
expression control sequences include, for example, the
early and late promoters of SV40 or adenovirus, the
promoter for 3-phosphoglycerate kinase or other
glycolytic enzymes, the promoters of acid phosphatase,
e.g., Pho5, the promoters of the yeast ~-mating system
and other sequences known to control the expression of
genes of eukaryotic cells or their viruses, and various
combinations thereof.
It should of course be understood that not
all vectors and expression control sequences will
function equally well to express the DNA sequences
described herein. Neither will all cells function
equally well with the same expression system. However,
one of skill in the art may make a selection among

these vectors, expression control sequences and cells
without undue experimentation. For example, in
selecting a vector, the host cell must be considered
because the vector must replicate in it. The vector's
copy number, the ability to control that copy number,
and the expression of any other proteins encoded by the
vector, such as antibiotic markers, should also be
considered.
In selecting an expression control sequence,
a variety of factors should also be considered. These
include, for example, the relative strength of the
sequence, its controllability, and its compatibility
with the actual DNA sequence encoding the desired
analgesic compounds, particularly as regards potential
secondary structures. Host cells should be selected by
consideration of their compatibility with the chosen
vector, the toxicity of the product coded for by the
DNA sequences, their secretion characteristics, their
ability to fold the polypeptides correctly, and their
culture requirements. If the host cell is to be
encapsulated, cell viability when encapsulated and
implanted in a recipient should also be considered.
Within these parameters, one of skill in the
art may select various vector/expression control
sequence/host combinations that will express the
desired DNA sequences in culture.
In one embodiment, cells (e.g., RIN cells)
are sequentially transformed with 4 separate expression
vectors containing the POMC gene, the pro-enkephalin A
gene, the TH gene and the DBH gene. In such a
transformed host cell, amplification of copy number of
the heterologous genes is more difficult to achieve.

Thus use of fewer expression vectors is preferred. Most
preferably, a single expression vector, containing all
4 heterologous genes, is used.
In a particular embodiment RIN cells are
5 sequentially transformed with 3 expression vectors.
The first vector contains the POMC gene operably linked
to the CMV promoter. Preferably a truncated version of
the POMC gene is used, having the ACTH coding region
deleted. The second vector contains the pro-enkephalin
10 A gene operably linked to the CMV promoter. Preferably
the proA construct contains the Kozak sequence
immediately upstream of the start codon. The third
vector contains both the TH gene (preferably truncated
and having the Kozak consensus sequence immediately
upstream of the start codon) and the DBH gene. In this
embodiment, the TH gene is operably linked to the CMV
promoter. The DBH gene is operably linked to an
internal ribosome entry site promoter sequence. RIN
cells are then transformed sequentially with each
20 expression vector according to known protocols.
In another embodiment, a single expression
vector containing the pro-enkephalin A gene, the POMC
gene, the TH gene, and the DBH gene is constructed.
Preferably, the ACTH region of the POMC gene is
25 deleted. Preferably the TH gene is truncated.
Multiple gene expression from a single
transcript is preferred over expression from multiple
transcription units. One approach for achieving
expression of multiple genes from a single eukaryotic
30 transcript takes advantage of sequences in picorna
viral mRNAs known as internal ribosome entry sites
("IRES"). These sites function to facilitate protein

translation from sequences located downstream from the
first AUG of the mRNA.
Macejak and Sarnow reported that the 5'
untranslated sequence of the immunoglobulin heavy chain
binding protein (BiP, also known as CRP 78, the
glucose-regulated protein of molecular weight 78,000)
mRNA can directly confer internal ribosome binding to
an mRNA in mAmm~ lian cells, in a 5'-cap independent
manner, indicating that translation initiation by an
o internal ribosome binding mechanism is used by this
cellular mRNA. Nature 353, pp. 90-94 (1991).
W0 94/24870 refers to use of more than two
IRES for translation initiation from a single
transcript, as well as to use of multiple copies of the
same IRES in a single construct.
This invention also contemplates use of a
"suicide" gene in the transformed cells. Most
preferably, the cell carries the TK (thymidine kinase)
gene as a safety measure, permitting the host cell to
be killed in v vo by treatment with gancyclovir.
Use of a "suicide" gene is known in the art.
See, e.g., Anderson, published PCT application
W0 93/10218; Hamre, published PCT application
W0 93/02556. The recipient's own immune system
provides a first level of protection from adverse
reactions to the implanted cells. If encapsulated, the
polymer capsule itself may be immuno-isolatory. The
presence of the TK gene (or other suicide gene) in the
expression construct adds an additional level of safety
to the recipient of the implanted cells.
Preferred vectors for use in this invention
include those that allow the DNA encoding the analgesic

compounds to be amplified in copy number. Such
amplifiable vectors are well known in the art. They
include, for example, vectors able to be amplified by
DHFR amplification (see, e.g., Kaufman, United States
Patent 4,470,461, Kaufman and Sharp, "Construction Of A
Modular Dihydrafolate Reductase cDNA Gene: Analysis Of
Signals Utilized For Efficient Expression", Mol. Cell.
Biol., 2, pp. 1304-19 (1982)) or glutamine synthetase
("GS") amplification (see, e.g., United States patent
5,122,464 and European published application 338,841).
Such amplification can be used to increase output of
the desired analgesic compounds.
Other techniques for increasing the output of
the desired analgesic compounds are contemplated. For
example, subcloning existing polyclonal cell lines is
contemplated. Cells are cloned by limiting dilution to
a single cell in each well. Cell clones are cultures,
and the clones are tested to select the clone with the
highest output of analgesic substances.
Another technique for increasing the output
of the desired analgesic compounds involves cloning
altered forms of biosynthetic enzymes with higher
activity than the wild type form (i.e., the truncated
TH 1-155). Some truncated forms of TH have 4-6 times
increased activity over the wild type form of TH. See,
e.g., Daubner et al., "Expression and characterization
of catalytic and regulatory domains of rat tyrosine
hydroxylase" Protein Science, 2, pp. 1452-60 (1993).
In addition, use of tyrosine-free media to
select to increase tetrahydrobiopterin cofactor levels
may potentially increase tyrosine hydroxylase activity.

The cells of this invention may be implanted
into a mammal, including a human, for the treatment of
pain. If implanted unencapsulated, any suitable
implantation protocol may be used, including those
outlined by Sagen el- al., United States patent
4,753,635, incorporated herein by reference.
It may be desirable to encapsulate the
genetically modified cells of this invention before
implantation. Such encapsulated cells form a
bioartificial organ ("BAO"). BAOs may be designed for
implantation in a recipient or can be made to function
extra-corporeally. The BAOs useful in this invention
typically have at least one semipermeable outer surface
membrane or jacket surrounding a cell-containing core.
The jacket permits the diffusion of nutrients,
biologically active molecules and other selected
products through the BAO. The BAO is biocompatible.
In some cases, the membrane may serve to also
immunoisolate the cells by blocking the cellular and
molecular effectors of immunological rejection. The
use of immunoisolatory membranes allows for the
implantation of allo and xenogeneic cells into an
S~ ul~Shttl (RULE~6)
CA 02223246 1997-12-02
W O 96/40959 PCTAUS96/09629
individual without the use of immunosuppression. If
biologically active molecules are released from the
isolated cells, they pass through the surrounding
semipermeable membrane into the recipient's body. If
metabolic functions are provided by the isolated cells,
the substances to be metabolized enter the BAO from the
recipient's body through the membrane to be acted on by
the cells.
A variety of types of membranes have been
used in the construction of BAQs. Generally, the
membranes used in BAOs are either microporous or
ultrafiltration grade membranes. A variety of membrane
materials have been suggested for use in BAOs,
including PAN/PVC, polyurethanes, polysufones,
polyvinylidienes, and polystyrenes. Typical membrane
geometries include flat sheets, which may be fabricated
into "sandwich" type constructions, having a layer of
living cells positioned between two essentially planar
membranes with seals formed around the perimeter of the
device. Alternatively, hollow fiber devices may be
used, where the living cells are located in the
interior of a tubular membrane. Hollow fiber BAOs may
be formed step-wise by loading living cells in the
lumen of the hollow fiber and providing seals on the
ends of the ~iber. Hollow fiber BAOs may also be
formed by a coextrusion process, where living cells are
coextruded with a polymeric solution which forms a
membrane around the cells.
BAOs have been described, for example, in
30 United States patent Nos. 4,892,538, 5,106,627,
5,156,844, 5,158,881, and 5,182,111, and PCT

93/03901, and WO 91/00119, all of which are
incorporated herein by reference.
BAOs may contain other components that
promote long term survival of the encapsulated cells.
5 For example, WO 92/19195 refers to implantable
immllnoisolatory biocompatible vehicles having a
hydrogel matrix for enhancing cell viability.
The encapsulating membrane of the BAO may be
made of a material which is the same as that of the
core, or it may be made of a different material. In
either case, a surrounding or peripheral membrane
region of the BAO which is permselective and
biocompatible will be formed. The membrane may also be
constructed to be immunoisolatory, if desired. The
core contains isolated cells, either suspended in a
liquid medium or immobilized within a hydrogel matrix.
The choice of materials used to construct the
BAO is determined by a number of factors and is
described in detail in Dionne WO 92/19195. Briefly,
various polymers and polymer blends can be used to
manufacture the capsule jacket. Polymeric membranes
forming the BAO and the growth surfaces therein may
include polyacrylates (including acrylic copolymers),
polyvinylidenes, polyvinyl chloride copolymers,
2s polyurethanes, polystyrenes, polyamides, cellulose
acetates, cellulose nitrates, polysulfones,
polyphosphazenes, polyacrylonitriles,
poly(acrylonitrile/covinyl chloride), as well as
derivatives, copolymers and mixtures thereof.
BAOs may be formed by any suitable method
known in the art. One such method involves coextrusion
of a polymeric casting solution and a coagulant which
SUBSIIlul~ SHEEr (RUI~ ~6)
CA 02223246 1997-12-02
W O 96/40959 PCT~US96/09629
can include biological tissue fragments, organelles, or
suspensions of cells and/or other therapeutic agents,
as described in Dionne, WO 92/19195 and United States
Patents 5,158,881, 5,283,187 and 5,284,761,
s incorporated herein by reference.
The jacket may have a single skin or a double
skin. A single-skinned hollow fiber may be produced by
quenching only one of the surfaces of the polymer
solution as it is co-extruded. A double-skinned hollow
lo fiber may be produced by quenching both surfaces of the
polymer solution as it is co-extruded.
Numerous capsulè configurations, such as
cylindrical, disk-shaped or spherical are possible.
The jacket of the BA0 will have a pore size
S that determines the nominal molecular weight cut off
(nMWC0) of the permselective membrane. Molecules
larger than the nMWCO are physically impeded from
traversing the membrane. Nominal molecular weight cut
off is defined as 90~ rejection under convective
conditions. In situations where it is desirable that
the BAO is immunoisolatory, the membrane pore size is
chosen to permit the particular factors being produced
by the cells to diffuse out of the vehicle, but to
exclude the entry of host immune response factors into
the BAO. Typically the nMWC0 ranges between 50 and 200
kD, preferably between 90 and 150 kD. The most
suitable membrane composition will also minimize
reactivity between host immune effector molecules known
to be present at the selected implantation site, and
the BAO's outer membrane components.
The core of the BAO is constructed to provide
a suitable local environment for the particular cells

isolated therein. The core can comprise a liquid
medium sufficient to maintain cell growth. Liquid
cores are particularly suitable for maintaining
transformed cell lines like PC12 cells. Alternatively,
the core can comprise a gel matrix. The gel matrix may
be composed of hydrogel (alginate, "Vitrogen~", etc.)
or extracellular matrix components. See, e.g., Dionne
WO 92/19195.
Compositions that form hydrogels fall into
0 three general classes. The first class carries a net
negative charge (e.g., alginate). The second class
carries a net positive charge (e.g., collagen and
l~in;n) . Examples of commercially available
extracellular matrix components include Matrigel~ and
Vitrogen~. The third class is net neutral in charge
(e.g., highly crosslinked polyethylene oxide, or
polyvinylalcohol).
Any suitable method of sealing the BAO may be
used, including the employment of polymer adhesives
and/or crimping, knotting and heat sealing. These
sealing techniques are known in the art. In addition,
any suitable "dry" sealing method can also be used. In
such methods, a substantially non-porous fitting is
provided through which the cell-containing solution is
introduced. Subsequent to filling, the BAO is sealed.
Such a method is described in copending United States
application Serial No. 08/082,407, herein incorporated
by reference.
One or more in vitro assays are preferably
used to establish functionality of the BAO prior to
implantation in vivo. Assays or diagnostic tests well
known in the art can be used for these purposes. See,

e.g., Metho~s In Fnzymoloay, Abelson [Ed], Academic
Press, 1993. For example, an ELISA (enzyme-linked
immllnosorbent assay), chromatographic or enzymatic
assay, or bioassay specific for the secreted product
can be used. If desired, secretory function of an
implant can be monitored over time by collecting
appropriate samples (e.g., serum) from the recipient
and assaying them. If the recipient is a primate,
microdialysis may be used.
The number of BAOs and BAO size should be
sufficient to produce a therapeutic effect upon
implantation is determined by the amount of biological
activity required for the particular application. In
the case of secretory cells releasing therapeutic
substances, standard dosage conslderations and criteria
known to the art are used to determine the amount of
secretory substance required. Factors to be considered
are discussed in Dionne, WO 92/19195.
Implantation of the BAO is performed under
sterile conditions. Generally, the BAO is implanted at
a site in the host which will allow appropriate
delivery of the secreted product or function to the
host and of nutrients to the encapsulated cells or
tissue, and will also allow access to the BAO for
retrieval and/or replacement. The preferred host is a
primate, most preferably a human.
A number of different implantation sites are
contemplated. These implantation sites include the
- central nervous system, including the brain, spinal
cord, and aqueous and vitreous humors of the eye.
Preferred sites in the brain include the striatum, the
cerebral cortex, subthalamic nuclei and nucleus Basalis

cerebrospinal fluid, most preferably the subarachnoid
space and the lateral ventricles. This invention also
contemplates implantation into the kidney subcapsular
site, and intraperitoneal and subcutaneous sites, or
any other therapeutically beneficial site.
In order that this invention may be better
understood, the following examples are set forth.

Cloning of Full Length and Truncated TH cDNA
Total RNA from PC12 cells was prepared using
the guanidinium thiocyanate-based TRI reagent
(Molecular Research Center, Inc., Cincinnati, OH).
Five hundred ng of PC12 total RNA was reverse
transcribed at 42~C for 30 minutes in a 20~1 reaction
volume containing 10 mM Tris.HCl (pH 8.3), 50 mM KC1,
4 mM of each dNTP, 5 mM MgC12, 1.25 ~M oligo (dT) 15-
15 mer, 1.25 l~M random hexamers, 31 units of RNase Guard
RNase Inhibitor (Pharmacia, Sweden) and 200 units of
SuperScript II reverse transcriptase (Gibco BRL,
Gaithersburg, MD). Two micro-liters of the above
reverse transcribed cDNA was added to a 25 ul PCR
20 reaction mixture containing 10 mM Tris.HCl (pH 8.3),
50 mM KCl, 800 of each nM dNTP, 2 mM MgC12, 400 nM of
primers #1 and #2, and 2.5 units of Thermus aquaticus

To generate the full length TH cDNA,
25 oligonucleotide primers orTH-052 (SEQ ID NO: 5) and

TH, primers orTH-054 (SEQ ID NO: 7) and orTH-053 (SEQ

were constructed based on published TH sequence

(solution #l) was added to the plasmid DNA. A 500 ~1
amount of solution #2 was immediately added to the DNA
containing solution and mixed gently. This was
incubated at room temperature for 20 minutes and then
the 1.0 ml solution was added to the cells in the petri
dish. The cells were incubated overnight and 18-24
hours later the cells were washed 2x with Hanks
balanced salt solution without calcium and magnesium.
Then, the cells were cultured in base media + selection
drugs. The cells were selected in either 600 ~g/ml
geneticin (Gibco) or 400 ug/ml hygromycin (Boehringer
Mannheim) or 500 ug/ml Zeocin (In Vitrogen, San Diego,
CA). Cells were sequentially transfected and selected
to obtain the final cell line.
The RINa cells were transfected with plasmid
pCEP4-hPOMC-030 containing the POMC gene. This is a
hygromycin resistant vector. The cells were also
transformed with plasmid pcDNA3-hProA+KS-091. This is
a geneticin resistant vector. Finally, the cells were
transfected with plasmid pZeo-PCMV-rTH~KS-IRES-bDBH-088
which conferred Zeocin resistance.
The AtT-20 cells were transfected with
plasmid pBS-CMV-ProA and pCEP4-POMC-~ACTH-32 which
conferred geneticin and hygromycin resistance,
respectively. Finally, the cells were transfected with
plasmid pZeo-Pcmv-rTH~KS-IRES-bDBH-088.

for 20 minutes in a 37~C waterbath. After the 20
~ minute digest, samples are returned to ice and 100
ng/ml carboxypeptidase B (Sigma #C-7011) is added.
Samples are mixed by vortexing, and returned to the
37~C waterbath for 15 minutes. Samples are placed on
ice once more and 10 ug/ml trypsin inhibitor is added.
At this stage, samples are either extracted for met-
enkephalin or immediately frozen for future extraction.
This results in the full enzymatic cleavage to free all
met-enkaphalin from the longer encrypted fragments. A
met-enkaphalin radioimmunoassay of the digested sample
gives total met-enkaphalin from the supermatant. The
transformed RINa cells appear to have greater than 5
fold more encrypted enkaphalins compared to fully
processed met-enkaphalin.

glue with blue light, and repeating the step with a
second drop. The opposite end is previously attached
to a frangible necked hub assembly, having a silicone
septum through which the cell solution may be
introduced. The fiber is glued to the hub assembly by
applying LCM 22 to the outer diameter of the hub
assembly, pulling the fiber up over it, and curing with
0 blue light. The hub/fiber assemblies are placed in
sterili~ation bags and are ETO sterilized.
Following sterilization with ethylene oxide
and outgassing, the fibers are deglycerinated by
ultrafiltering first 70~ EtOH, and then HEPES ~uffered
saline solution through the walls of the fiber under
vacuum.
Prepar~tion and Fncapsulation of Transformed Cells
The transformed cells are prepared and
encapsulated as follows:
A matrix solution is prepared using a
commercially availab~e alginate, collagen or other
suitable matrix material. The cell solution was
diluted in the ratio of two parts matrix solution to
one part cell solution containing the transformed cells
described above. We prefer Vitrogen (Celtix, Santa
Clara) as a matrix for AtT-20 cells.
We prefer Organogen (Organogenesis, Canton,
MA) as a matrix for RINa cells. The RINa based cells
are prepared for encapsulation by the following method.
The cells are grown in base media of DMEM + 10% fetal
bovine serum during the proliferation phase. These

cells can be removed from the tissue culture flasks by
two washes in Hanks balanced salt solution without
~ calcium and magnesium. Then the cells are incubated in
0.25% trypsin + EDTA for 1 minute. This is removed and
the cells are rinsed free of the flask using Hanks
balanced salt solution without calcium and magnesium
solution. The cells are placed in 10 mls of base media
and centrifuged at 100 x g for 2 minutes. The cells
are resuspended in 10 mls of the preferred serum free
media (Ultra culture, Biowhitaker, Walkersville, MD).
Surprisingly, the RINa cells secrete more analgesiç
substances when cultured in this serum free media
relative to serum continuing base media.
The cells are centrifuged at 100 g twice in
the preferred serum free media before the cells are
concentrated 1:1 with the preferred Organogen matrix.
Organogen is a 1% bovine tendon collagen obtained as a
sterile solution. 8 parts of this solution are mixed
with 1 part 10X DPBS. 0.5 N sodium hydroxide is added
until physiological pH is attained (approximately
2S0 uls).
The final concentration of the cell + matrix
solution used for encapsulation can range from 20,000 -
50,000 cells/~l. The cells are counted in a standard
manner on a hemocytometer.
The cell/matrix suspension is placed in a
1 ml syringe. A Hamilton 1800 Series 50 microliter
syringe is set for a 15 microliter air bubble, is
inserted into a 1 ml syringe containing the cell
solution and 30 microliters are drawn up. The cell

approximately 50,000-100,000 daltons. Ultrafiltration
should be observed along the entire length of the
fiber. After one minute, the hub is snapped off the
sub-hub, exposing a fresh surface, unwet by cell
solution. A single drop of LCM 2~ is applied and the
adhesive cured with blue light. The device is placed
first in HEPES buffered NaCl solution and then in CaC12
solution for five minutes to cross-link the alginate.
Each implant is about 5 cm long, 1 mm in diameter, and
contained approximately 2.5 million cells.
After the devices are filled and sealed, a
silicone tether (Speciality Silcone Fabrication, Paso
Robles, CA) (ID: 0.69, OD: 1.25) is then placed over
the proximal end of the fiber. A radiopaque titanium
plug is inserted in the lumen of the silicone tether to
act as a radiographic marker. The devices are then
placed in 100 mm tissue culture dishes in 1.5 ml PC-1
medium, and stored at 37~C, in a 5~ CO. incubator for
in vitro analysis and for storage until implantation.
The encapsulated cells are then implanted
into the human sub-arachnoid space as follows:
Sura~l Procedure
After establishing IV access and
administering prophylactic antibiotics (cefazolin
sodium, 1 gram IV), the patient is positioned on the
operating table, generally in either the lateral
decubitus or genu-pectoral position, with the lumbar
spine flexed anteriorly. The operative field is
sterily prepared and draped exposing the midline dorsal
lumbar region from the levels of S-1 to L-1, and

allowing for intraoperative imaging of the lumbar spinewith C-arm fluoroscopy. Local infiltration with 1.0%
lidocaine is used to establish anesthesia of the skin
as well as the periosteum and other deep connective
tissue structures down to and including the ligamentum
flavum.
A 3-5 cm skin incision is made in the
parasagital plane 1-2 cm to the right or left of the
midline and is continued down to the lumbodorsal
lo fascia using electrocautery for hemostasis. Using
traditional bony landmarks including the iliac crests
and the lumbar spinous processes, as well as
fluoroscopic guidance, and 18 gauge Touhy needle is
introduced into the subarachnoid space between L-3 and
L-4 via an oblique paramedian approach. The needle is
directed so that it enters the space at a shallow,
superiorly directed angle that is no greater than 30-
35~ with respect to the spinal cord in either the
sagittal or transverse plane. Appropriate position of
the tip of the needle is confirmed by withdrawal of
several ml of cerebrospinal fluid (CSF) for
preimplantation catecholamine, enkephalin, glucose, and
protein levels and cell counts.
The Touhy needle hub is reexamined to confirm
that the opening at the tip is oriented superiorly
(opening direction is marked by the indexing notch for
the obturator on the needle hub), and the guide wire is
passed down the lumen of the needle until it extends 4-
5 cm into the subarachnoid space (determined by
premeasuring). Care is taken during passage of the
wire that there is not resistance to advancement of the
wire out of the needle and that the patient does not

complain of significant neurogenic symptoms, either of
which observations might indicate misdirection of the
guide wire and possible impending nerve root or spinal
cord injury.
After the guide wire appears to be
appropriately placed in the subarachnoid space, the
Touhy needle is separately withdrawn and removed from
the wire. The position of the wire in the midline of
the spinal canal, anterior to the expected location of
o the caud equina, and without kinks or unexplainable
bends is then confirmed with fluoroscopy. After
removal of the Touhy needle the guide wire should be
able to be moved freely into and out of the space with
only very slight resistance due to the rough surface of
lS the wire running through the dense and fibrous
ligamentum flavum.
The 7 French dilator is then placed over the
guide wire and the wire is used to direct the dilator
as it is gently but firmly pushed through the fascia,
paraspinous muscle, and ligamentum flavum, following
the track of the wire toward the subarachnoid space.
Advancement of the 7 French dilator is stopped and the
dilator removed from the wire as soon as a loss of
resistance is detected after passing the ligamentum
flavum. This is done in order to avoid advancing and
manipulating this relatively rigid dilator within the
subarachnoid space to any significant degree.
After the wire track is "overdilated" by the
7 French dilator, the 6 French dilator and cannula
sheath are assembled and placed over the guide wire.
The 6 French dilator and cannula are advanced carefully
into the subarachnoid space until the opening tip of
~ ultSh~ RUL~26)

-- 51 --
the cannula is positioned 7 cm within the space. As
with the 7 French dilator, the assembled 6 French
t dilator and cannula are directed by the wire within the
lumen of the dilator. Position within the subarachnoid
s space is determined by premeasuring the device and is
grossly confirmed by fluoroscopy. Great care is taken
with manipulation of the dilators and cannula within
the subarachnoid space to avoid misdirection and
possible neurologic injury.
o When appropriate positioning of the cannula
is assured, the guide wire and the 6 French dilator are
gently removed from the lumen of the cannula in
sequence. Depending on the patient's position on the
operating table, CSF flow through the cannula at this
point should be noticeable and may be very brisk,
requiring capping the cannula or very prompt placement
of the capsule implant in order to prevent excessive
CSF.
The encapsulated (transformed cells) is
provided in a sterile, double envelope container,
bathed in transport medium, and fully assembled
including a tubular sillcone tether. Prior to
implantation through the cannula and into the
subarachnoid space, the capsule is transferred to the
insertion kit tray where it is positioned in a location
that allowed the capsule to be maintained in transport
medium while it is grossly examined for damage or major
defects, and while the silicone tether is trimmed,
adjusting its length to the pusher and removing the
hemaclip~ that plugs its external end.
The tether portion of the capsule is mounted
onto the stainless steel pusher by inserting the small

diameter wire portion of the pusher as the membrane
portion of the device is carefully introduced into the
cannula. The capsule is advanced until the tip of the
membrane reaches a point that is 2-10 mm within the
cranial tip of the cannula in the subarachnoid space.
This placement is achieved by premeasuring the cannula
and the capsule-tether-pusher assembly, and it assures
that the membrane portion of the capsule is protected
by the cannula for the entire time that it is being
o advanced into position.
After the capsule is positioned within the
cannula, the pusher is used to hold the capsule in
position (without advancing or withdrawing) in the
subarachnoid space while the cannula is completely
withdrawn from over the capsule and pusher. The pusher
is then removed from the capsule by sliding its wire
portion out of the silicone tether. Using this method
the final placement of the capsule is such that the 5
cm long membrane portion of the device lay entirely
within the CSF containing subarachnoid space ventral to
the cauda equina. It is anchored at its caudal end by
a roughly 1-2 cm length of silicone tether that runs
within the subarachnoid space before the tether exits
through the dura and ligamentum flavum. The tether
continues externally from this level through the
paraspinous muscle and emerges from the lumbodorsal
fascia leaving generally 10-12 cm of free tether
material that is available for securing the device.
CSF leakage is min;m; zed by injecting fibrin
glue (Tissel~) into the track occupied by the tether in
the paraspinous muscle, and by firmly closing the
superficial fascial opening of the track with a purse-

string suture. The free end of the tether is then
anchored with non-absorbable suture and completely
covered with a 2 layer closure of the skin and
subcutaneous tissue.
The patient is then transferred to the
neurosurgical recovery area and kept at strict bed
rest, recumbent, for 24 hours postoperatively.
Antibiotic prophylaxis is also continued for 24 hours
following the implantation procedure.
