COMPOSITIONS AND METHODS FOR RECOMBINANT AAV PRODUCTION
TECHNICAL FIELD
[0001] The present disclosure relates to recombinant polynucleotides encoding
helper functions
and their use in a method of producing recombinant adeno-associated virus
(rAAV) particles.
CROSS-REFRENCE TO RELATED APPLICATIONS

filed October 5,
2021 and U.S. application no. 63/320,335, filed March 16, 2022, each of which
is incorporated

REFERENCE TO SEQUENCE LISTING SUBMITTED ELECTRONICALLY
[0003] The content of the electronically submitted sequence
listing (Name:
6728_1802_Sequence_Listing.xml; Size: 376,980 bytes; and Date of Creation:
September 13,
2022) filed with the application is incorporated herein by reference in its
entirety.
BACKGROUND
[0004] Recombinant adeno-associated virus (AAV)-based vectors are currently
the most widely
used gene therapy products in development. The preferred use of rAAV vector
systems is due, in
part, to the lack of disease associated with the wild-type virus, the ability
of AAV to transduce
non-dividing as well as dividing cells, and the resulting long-term robust
transgene expression
observed in clinical trials and that indicate great potential for delivery in
gene therapy indications.
Additionally, different naturally occurring and recombinant rAAV vector
serotypes, specifically
target different tissues, organs, and cells, and help evade any pre-existing
immunity to the vector,
thus expanding the therapeutic applications of AAV-based gene therapies.
Before replication
defective virus, for example, AAV based gene therapies can be more widely
adopted for late
clinical stage and commercial use, new methods for large scale production of
recombinant virus
particles need to be developed.
[0005] Thus, there is a need in the art to improve the productivity and yield
of methods for the
large scale production of rAAV particles.

DETAILED DESCRIPTION
[0033] In one aspect, provided herein are improved recombinant polynucleotides
and plasmids
encoding helper functions suitable for use in the production of recombinant
AAV particles. In
some embodiments, the recombinant polynucleotides and plasmids encode one or
more of an
adenovirus E2A DNA binding protein, a nucleotide sequence encoding an
adenovirus E4 ORF6
and ORF7 polypeptide and a nucleotide sequence encoding an adenovirus VA RNA
I. In some
embodiments, the polynucleotides and plasmids do not comprise a nucleotide
sequence encoding
an adenovirus ITR sequence, L3 23K endoprotease, L5 pVI/fibre, and/or L4
pVIII/hexon-
associated precursor. In some embodiments, the polynucleotides and plasmids
are smaller than
previously available polynucleotides and plasmids encoding helper functions
suitable for use in
the production of recombinant AAV particles. In some embodiments, use of the
improved
polynucleotides and plasmids described herein in the production of recombinant
AAV particles
results in increased rAAV yield.

[00136] Numerous cell culture based systems are known in the art for
production of rAAV
particles, any of which can be used to practice a method described herein.
rAAV production
cultures for the production of rAAV virus particles require; (1) suitable host
cells, including, for
example, human-derived cell lines such as HeLa, A549, or HEK293 cells and
their derivatives
(HEK293T cells, HEK293F cells), or mammalian cell lines such as Vero,
amniocyte-derived cells
such as CAP cells, CHO cells or CHO-derived cells; (2) suitable helper virus
function, provided
by wild type or mutant adenovirus (such as temperature sensitive adenovirus),
herpes virus,
baculovirus, or a plasmid construct providing helper functions; (3) AAV rep
and cap genes and
gene products; (4) a transgene (such as a therapeutic transgene) flanked by
AAV ITR sequences;
and (5) suitable media and media components to support rAAV production.
[00137] A skilled artisan is aware of the numerous methods by which AAV rep
and cap genes,
AAV helper genes (e.g., adenovirus El a gene, Elb gene, E4 gene, E2a gene, and
VA gene), and
rAAV genomes (comprising one or more genes of interest flanked by inverted
terminal repeats
(ITRs)) can be introduced into cells to produce or package rAAV. The phrase
"adenovirus helper
functions" refers to a number of viral helper genes expressed in a cell (as
RNA or protein) such
that the AAV grows efficiently in the cell. The skilled artisan understands
that helper viruses,
including adenovirus and herpes simplex virus (HSV), promote AAV replication
and certain
genes have been identified that provide the essential functions, e.g. the
helper may induce
changes to the cellular environment that facilitate such AAV gene expression
and replication. In

genes, and
rAAV genomes are introduced into cells by transfection of one or more plasmid

according to a
method disclosed in WO 2019/241535, which is incorporated herein by reference
in its entirety.
[00196] In some embodiments, a method of isolating rAAV particles comprises
determining the
vector genome titer, capsid titer, and/or the ratio of full to empty capsids
in a composition

titer and capsid titer of a composition comprising the isolated recombinant
rAAV particles are
disclosed in WO 2019/212922, which is incorporated herein by reference in its

[00198] In additional embodiments the disclosure provides compositions
comprising isolated
rAAV particles produced according to a method described herein. In some
embodiment, the
composition is a pharmaceutical composition comprising a pharmaceutically
acceptable carrier.
[00199] As used herein the term "pharmaceutically acceptable means a
biologically acceptable
formulation, gaseous, liquid or solid, or mixture thereof, which is suitable
for one or more routes
of administration, in vivo delivery or contact. A "pharmaceutically
acceptable" composition is a
material that is not biologically or otherwise undesirable, e.g., the material
may be administered
to a subject without causing substantial undesirable biological effects. Thus,
such a
pharmaceutical composition may be used, for example in administering rAAV
isolated according
to the disclosed methods to a subject. Such compositions include solvents
(aqueous or non-
aqueous), solutions (aqueous or non-aqueous), emulsions (e.g., oil-in-water or
water-in-oil),
suspensions, syrups, elixirs, dispersion and suspension media, coatings,
isotonic and absorption
promoting or delaying agents, compatible with pharmaceutical administration or
in vivo contact
or delivery. Aqueous and non-aqueous solvents, solutions and suspensions may
include
suspending agents and thickcning agents. Such pharmaceutically acceptable
carriers include
tablets (coated or uncoated), capsules (hard or soft), microbeads, powder,
granules and crystals.
Supplementary active compounds (e.g., preservatives, antibacterial, antiviral
and antifungal
agents) can also be incorporated into the compositions. Pharmaceutical
compositions can be
formulated to be compatible with a particular route of administration or
delivery, as set forth
herein or known to one of skill in the art. Thus, pharmaceutical compositions
include carriers,
diluents, or excipients suitable for administration by various routes.

EXAMPLES
Example 1. Development of improved helper plasmids.
[00201]
Plasmid pAdDeltaF6 was constructed by Dr. James M. Wilson and colleagues
at
UPenn. pAdDe1taF6 is 15770 bp in size. The plasmid contains the regions of
adenovirus genome
CA 03233468 2024- 3- 28

WO 2023/060113
PCT/US2022/077587
that are important for AAV replication, namely E2A (DNA binding protein), E4,
and VA RNAI
but does not contain other adenovirus replication genes. This plasmid was
derived from an El, E3
deleted molecular clone of Ad5 (pBHG10, a pBR322 based plasmid). Deletions
were introduced
in the Ad5 DNA to remove expression of unnecessary adenovirus genes and reduce
the amount of
adenovirus DNA from 32 kb to 12 kb (Figure 1, A). Finally, the ampicillin
resistance gene was
replaced by the kanamycin resistance gene to give pAdDe1taF6 (Figure 1, B).
The functional
elements of the E2A. E4 and VA RNAI adenoviral genes necessary for AAV vector
production
remain in this plasmid. The adenoviral El essential gene functions are
supplied by the HEK293
cells. There are also some remnant genes/elements that were resulted from
partial digestion of
pBHG10. These include the promoterless L3 23K/viral endoprotease, L4
100K/hexon assembly
gene, L4 pVIII/hexon-associated precursor and L5 pVI/fiber genes in the map.
Figure 1 C). In
pAdDeltaF6 plasmid, these genes are not transcribed due to the deletion of
their promoter MLP
(Major Late Promoter). Biasiotto et al., Int. J. Mol. Sci., 16: 2893-2912;
doi:10.3390/ijms16022893 (2015). Since some of these genes including L4 100K
and L4 pVIII
overlap with E2A region, deletion of these genes may impact the production of
the essential
helper protein E2A as described below during the sequential reconfiguration of
the helper
plasmid. Furthermore, there is a L4 22K/33K gene with its own intact promoter
located at this
region. This gene encodes the L4 22K and L4 33K proteins involved in
Adenovirus 5 packaging.
The promoter of the L4 22K/33K gene also overlaps with E2A region. Therefore,
deletion of the
promoter may impact the production of E2A. There is a partial adenoviral
inverted terminal
repeat in thc plasmid map that also resulted from partial digestion of pBHG10.
However, due to
the deletion of the essential DNA polymerase gene (E2 region) for Adenovirus 5
DNA
replication, no infectious adenovirus is expected to be generated. DNA plasmid
sequencing was
performed by Qiagen Genomic Services and revealed 100% homology with the
following
important functional elements of the reference sequence pAdDeltaF6 p1707FH-Q:
E4 ORF6
3692-2808 bp; E2A DNA binding protein 11784-10194 bp; VA RNAI region 12426-
13378 bp.
The sequence is confirmed at Aldevron, as part of the manufacturing process.
[00202] New helper plasmid #1 The new helper plasmid #1 (Figure 2) was
constructed based on
Ad5 sequence where E2A and E4 orientations were re-configured to express them
bidirectionally.
The rationale behind this was to avoid possible interference from E4 strong
promoter which could
result in lowering the expression from E2A promoter located downstream. The
new helper
91
CA 03233468 2024- 3- 28

WO 2023/060113
PCT/US2022/077587
plasmid #1 genes were synthesized by Genscript and cloned into EcoRI/NotI
sites of pUC57
vector that was freely available from Genscript. In this new designed plasmid,
some nonessential
remnant genes (Ad5 structural genes) and elements that include the ITR
sequence (Ad5 inverted
terminal repeat) next to E4 promoter, L3 23K/viral endoprotease, L5 pVI/fibre,
and L4
pVIII/hexon-associated precursor sequences were removed. On the other hand,
the L4 33K/L4
100K hcxon assembly gene was kept since the E2A transcription starting sites
(TSS) arc located
at that region and their removal may impact E2A expression. The virus
associated (VA) RNA
was further modified by incorporating VA RNAII to VA RNA1. VA RNA is known to
stimulate
viral protein synthesis in infected cells and antagonizes the interferon-
induced cellular defense
system by regulating innate cellular response (Ma et al., Journal of Virology,
Aug. 1996, p 5083-
5099). The new plasmid has the size of 11,484 bp.
[00203] The new helper plasmid #1 improved AAV titers and
performed well on different
transgenes as shown in Figure 3. rAAV production titers were assessed using
the clone 1, 2, 3, 4,
and 5 HEK293-derived host cells.
[00204] New helper plasmid #2 The new helper plasmid #2 (Figure
4) was designed
based on the new helper #1. In this new design, the E4 region was dissected by
sequential
deletion and the impact of the deletions on AAV production was investigated.
E4 Orf 1 and 2
were deleted based on results indicating that deletion of E4 Orf 1 and 2
improved AAV titers
(data not shown). It is known in the field that the promoter controlling E4
region is active at
earlier phase of adenovirus infection and continues to the late phases. The E4
region has the
potential to transcribe and encode for 7 different proteins that are resulted
from differential
splicing of a single primary transcript (Orf1, 2, 3, 3/4, 4, 6, 6/7) generated
by this promoter. The
pattern of differential splicing for this transcript changes during the phases
of viral infection with
some appearing only in early phases and other in late phase (Dix et al.,
Journal of General
Virology (1995), 76, 1051-1055). The encoded protein products of Orfl, 0rf2,
0rf3, 0r14, 0rf6,
and 0rf6/7 were reported to exist in infected cells except for 0rf3/4, which
might be absent or
expressed below detection limit (Tauber et al., Gene 278 (2001) 1-23). Orfl
encoded protein is
expressed in the late phase and target a family of cellular proteins that play
a role in cell signaling
and signal transfection. There is no functional information about E4 product
encoded by 0rf2.
Furthermore, Ad5 mutants in which E4 0rf2 were deleted, were about to grow to
wild-type levels
(Tauber et al., Gene 278 (2001) 1-23). The deletion of Orfl and 2 did not
impact AAV production
92
CA 03233468 2024- 3- 28

WO 2023/060113
PCT/US2022/077587
but improved its titer which indicated that E4 Orfl and 2 are not essential
(Figure 5). rAAV
production titers were assessed using the clone 1, 2, 4, and 6 HEK293-derived
host cells.
[00205] New helper plasmid #3 During helper plasmid #3 design,
the E4 region was
further dissected by sequential deletion. Different E4 variants with E4 native
promoter and CMV
promoter were screened for AAV production (Figure 6). Those E4 variants with
E4 0rf6-7 only
gave the highest titers. E4 0rf3-4 was further removed from helper #2 to
generate helper #3
(Figure 7). To further explain the rationale behind removing 0rf3 and 0rf4, it
appears that 0rf3
and 0rf6 can partially or totally compensate for each other's defects. 0rf3
and 0rf6 have
redundant functions and independently amplify viral DNA replication, late
viral protein synthesis,
shut-off of host protein synthesis, and prevent concatemer formation of viral
genomes (Tauber et
al., Gene 278 (2001) 1-23). E4 0rf4 also downregulates E4 transcription by
inhibiting El A-
mediated transactivation of the E4 promoter through its interaction with the
serine/threonine
protein phosphatase 2A (PP2A), an enzyme that plays an important role on
numerous cellular
processes. This autoregulatory loop may be required to limit the cytotoxic
effects of E4 gene
products during the early phase of infection, where E4 0rf4 can induce
apoptosis through caspase
activation in a cell line-specific manner. Therefore, further removal of E4
0rf5 resulted in
prevention of this cytotoxic effect (Tauber et al., Gene 278 (2001) 1-23).
[00206] The helper #3 improved AAV titers including A AV8 and A
AV9, and different
transgenes (Figures 8 and 9). rAAV production titers were assessed using the
clone 1 and clone 4
HEK293-derived host cells.
[00207] New helper plasmid #4 The possibility of adding other
genes to the new helper
plasmid to further improve AAV titers was investigated. Incorporation of
selected genes from
Boca virus helper that were reported to have positive impact on AAV production
(Wang et al.,
Molecular Therapy: Methods & Clinical Development Vol.11 December 2018),
addition of a
copy of El A gene and AAP (assembly-activating protein derived from trans
plasmid) under
CMV promoter were explored. The addition of Boca virus selected genes NP1 and
NS2 genes to
helper plasmid #2 (Figure 10) had no impact on AAV titers (Figure 11). It is
known in the field
that the assembly activating protein encoded by AAV capsid can provide
increased capsid protein
stability when expressed in trans (Maurer et al., 2018, Cell Reports 23, 1817-
1830; Maurer et al.,
Journal Virology, 2019 Volume 93 Issue 7 e02013-18). The addition of AAP gene
expressed in
trans for AAV8 (Figure 12) had a negative impact on AAV titers (Figure 14).
ElA is known to
93
CA 03233468 2024- 3- 28

WO 2023/060113
PCT/US2022/077587
start AAV virus replication by enhancing the transcription from the rep gene
promoters, P5 and
P19 and by activating E2A and E4 adenovirus promoters. ElA is also known to
control the host
cell cycle to accommodate for AAV viral DNA replication. A potential drawback
from
overexpressing ElA is that it is known to stabilize p53, which can lead to
apoptosis. This can be
overcome by the E1B55K and the E4Orf6 proteins that will form a complex with
p53 and cause it
to be degraded (Matsushita et al., Journal of General Virology (2004), 85,
2209-2214; Meier et
al., Viruses 2020, 12, 662;). A copy of ElA under the control of CMV promoter
was added to the
helper plasmid #3 to create helper plasmid #4 (Figure 13). The location of ElA
was between E4
and VA RNA I/11. The results indicated that helper #4 further improved AAV
titers as shown in
Figure 14. rAAV production titers were assessed using the clone 1 and 4 HEK293-
derived host
cells.
[00208] New helper plasmids #5, #6, #7, #8 and #9 It is known that E2A, E4 and
VA RNA I/II
microRNA are essential helper components for AAV production (Meier et al.,
Viruses 2020, 12,
662; doi:10.3390/v12060662). In the current helper plasmids #1-4, L4
100K/hexon assembly and
L4 22K/33K were kept in the helper plasmid #3 because their genes are located
between the E2A
promoter and E2A open reading frame. This region might be important since two
E2A
transcription starting sites (TSS) are located at this region as documented
from the long-read
direct RNA sequencing study of Donovan-Banfield et al., (Communication Biology
(2020)
3:124). To test whether these two sequences could be removed while maintaining
high titer,
several mutations were generated based on helper #3 (Table 2). The analysis of
all these
mutations indicated that helper #5 and helper #8 gave similar titers or
slightly higher titers than
the helper plasmid #3 (Figure 15). rAAV production titers were assessed using
the clone 1 and 4
HEK293-derived host cells. In the helper plasmid #5, N-terminal region of
encoded hexon
assembly was removed, while in helper plasmid #8 the start codon was mutated
for the hexon
assembly region. On the other hand, all mutants in which L4 22K/33K start
codon was mutated
showed decrease in titers indicating that L4 22K/33K might be important for
AAV production.
These findings accord with the reported effect of L4 22K deletion, which
resulted in continuous
increase in E2A (DBP) expression in later phases and subsequently had a
negative impact on E4
expression (Wu et al., Journal of Virology (2012) p.10474-10483; Guimet et
al., Journal of
Virology (2013) p.7688-7699).

[00209] The new helper plasmids also improve the quality of rAAV particles
produced.
Compared to a production run performed with original helper in the
transfection process
