DETAILED DESCRIPTION

[0051] The present disclosure provides pharmaceutical compositions (e.g., formulations) that can provide for the long-term stability of AAV vectors. Also provided herein are methods of making and using the pharmaceutical compositions. The pharmaceutical compositions provided by the present disclosure generally comprise an AAV, a buffering agent (e.g., histidine), a stabilizing agent e.g., trehalose), a salt, and a surfactant. The pharmaceutical compositions described herein are particularly advantageous in that they enhance the stability of AAV vectors when challenged by thermal stress, including, for example, reducing the extent of vector aggregation, maintaining high vector genome titers, and maintaining AAV vector purity over time.

I. Definitions

[0052] As used herein, the term “recombinant adeno-associated virus” or “rAAV” refers to an adeno-associated virus (AAV) comprising a genome lacking functional rep and cap genes.

[0053] As used herein, the term “cap gene” refers to a nucleic acid sequence that encodes an AAV capsid protein. [0054] As used herein, the term “rAAV genome” refers to a nucleic acid molecule comprising the genome sequence of an rAAV. The skilled artisan will appreciate that where an rAAV genome comprises a transgene, the rAAV genome can be in the sense or antisense orientation relative to the direction of transcription of the transgene.

[0055] As used herein, the term “editing genome” refers to a recombinant AAV genome that is capable of integrating an editing element (e.g., one or more nucleotides or an internucleotide bond) via homologous recombination into a target locus to correct a genetic defect in a target gene. The skilled artisan will appreciate that the portion of an editing genome comprising the 5' homology arm, editing element, and 3' homology arm can be in the sense or antisense orientation relative to the target locus.

[0056] As used herein, the term “editing element” refers to the portion of an editing genome that when integrated at a target locus modifies the target locus. An editing element can mediate insertion, deletion, or substitution of one or more nucleotides at the target locus. As used herein, the term “target locus” refers to a region of a chromosome or an internucleotide bond (e.g., a region or an internucleotide bond of a target gene) that is modified by an editing element.

[0057] As used herein, the term “homology arm” refers to a portion of an editing genome positioned 5' or 3' of an editing element that is substantially identical to the genome flanking a target locus.

[0058] As used herein, the “percentage identity” between two nucleotide sequences or between two amino acid sequences is calculated by multiplying the number of matches between the pair of aligned sequences by 100, and dividing by the length of the aligned region, including internal gaps. Identity scoring only counts perfect matches and does not consider the degree of similarity of amino acids to one another. Note that only internal gaps are included in the length, not gaps at the sequence ends.

[0059] As used herein, the term “coding sequence” refers to the portion of a complementary DNA (cDNA) that encodes a polypeptide, starting at the start codon and ending at the stop codon. A gene may have one or more coding sequences due to alternative splicing, alternative translation initiation, and variation within the population. A coding sequence may be wild-type or a non-naturally occurring variant (e.g., a codon optimized variant).

[0060] As used herein, the term “transcriptional regulatory element” or “TRE” refers to a cis-acting nucleotide sequence, for example, a DNA sequence, that regulates (e.g., controls, increases, or reduces) transcription of an operably linked nucleotide sequence by an RNA polymerase to form an RNA molecule. A TRE relies on one or more trans-acting molecules, such as transcription factors, to regulate transcription. Thus, one TRE may regulate transcription in different ways when it is in contact with different trans-acting molecules, for example, when it is in different types of cells. A TRE may comprise one or more promoter elements and/or enhancer elements. A skilled artisan would appreciate that the promoter and enhancer elements in a gene may be close in location, and the term “promoter” may refer to a sequence comprising a promoter element and an enhancer element. Thus, the term “promoter” does not exclude an enhancer element in the sequence. The promoter and enhancer elements do not need to be derived from the same gene or species, and the sequence of each promoter or enhancer element may be either identical or substantially identical to the corresponding endogenous sequence in the genome.

[0061] As used herein, the term “operably linked” is used to describe the connection between a TRE and a coding sequence to be transcribed. Typically, gene expression is placed under the control of a TRE comprising one or more promoter and/or enhancer elements. The coding sequence is “operably linked” to the TRE if the transcription of the coding sequence is controlled or influenced by the TRE. The promoter and enhancer elements of the TRE may be in any orientation and/or distance from the coding sequence, as long as the desired transcriptional activity is obtained. In certain embodiments, the TRE is upstream from the coding sequence.

[0062] As used herein, the term “polyadenylation sequence” refers to a DNA sequence that, when transcribed into RNA, constitutes a polyadenylation signal sequence. The polyadenylation sequence can be native or exogenous. The exogenous polyadenylation sequence can be a mammalian or a viral polyadenylation sequence (e.g., an SV40 polyadenylation sequence).

[0063] As used herein, “exogenous polyadenylation sequence” refers to a polyadenylation sequence not identical or substantially identical to the endogenous polyadenylation sequence of a transgene. In certain embodiments, an exogenous polyadenylation sequence is a polyadenylation sequence of a gene different from the transgene, but within the same species (e.g., human). In certain embodiments, an exogenous polyadenylation sequence is a polyadenylation sequence of a different organism (e.g., a virus).

II. Recombinant Adeno-Associated Virus [0064] Pharmaceutical compositions (e.g., formulations) disclosed herein comprise an adeno-associated virus (AAV). In certain embodiments, the pharmaceutical compositions comprise a recombinant adeno-associated virus (rAAV). As exemplified in the experimental Examples herein, pharmaceutical compositions of the present disclosure provide long-term stability and allow for high titer AAV formulations. The pharmaceutical compositions described herein enhance the stability of AAV vectors when challenged by thermal stress, including, for example, reducing the extent of vector aggregation, maintaining high vector genome titers, and maintaining AAV vector purity over time. rAA V Genome

A A V Capsid Protein

[0089] In certain embodiments, the pharmaceutical compositions of the present disclosure comprise an rAAV comprising an AAV capsid. In certain embodiments, the AAV capsid comprises an AAV capsid protein. The rAAV can comprise an AAV capsid comprising an AAV capsid protein from any AAV capsid known in the art, including natural AAV isolates and variants thereof. [0090] AAV capsid proteins include VP1, VP2, and VP3 capsid proteins. VP1, VP2, and/or VP3 capsid proteins assemble into a capsid that surrounds the rAAV genome. In certain embodiments, assembly of the capsid proteins is facilitated by the assembly-activating protein (AAP). Capsids of certain AAV serotypes require the role of AAP in transporting the capsid proteins to the nucleolus for assembly. For example, AAV1, AAV2, AAV3, AAV6, AAV7, AAV8, AAV9, AAV10, and AAV12 require AAP to form capsids, while capsids of AAV4, AAV5, and AAV11 can assemble without AAP. See, e.g., Earley et al. (2017) J. Virol. 91(3): e01980-16.

V. Characteristics of the Formulations

[00150] Various methods of determining the titer of AAV in a pharmaceutical composition are known, for example, AAV vector genomes can be quantified using droplet digital PCR (ddPCR), and intact AAV particles can be quantified using an enzyme-linked immunosorbent assay utilizing an antibody specific for a conformational epitope on assembled AAV capsids (capsid ELISA). While ddPCR and capsid ELISA provide valuable information regarding the number of AAV vector genomes and intact AAV particles in a composition, other methods are known in the art which can distinguish between intact AAV particles containing vector genomes (“full” capsids) and intact AAV particles that contain partial vector genomes or that do not contain vector genomes (“empty” capsids). Such methods include vector capsid characterization by analytical ultracentrifugation (AUC) that provides a sedimentation profile that can determine the amount of full and empty capsids in a composition.

[00151] Various methods of AAV characterization and stability testing are known in the art, including, for example, vector aggregation characterization by size exclusion chromatography (SEC), vector protein characterization by capillary electrophoresis sodium dodecyl sulfate (CE- SDS) analysis, quantitation of residual reagents and plasmid supercoiling such as by reverse-phase chromatography and high performance liquid chromatography (HPLC), and detection and characterization of host cell protein contaminants by liquid chromatography and mass spectrometry (LC-MS).

[00166] The following Examples are offered by way of illustration, and not by way of limitation.

Example 1: Optimization of Adeno- Associated Virus Formulations

[00167] Several AAV vector formulations (Formulations 1-6) containing various concentrations of salt and stabilizing agent were generated. The components of these formulations are set forth in Table 1.

Table 1. Components of Formulations 1-6.

[00168] To assess the effect of salt concentration on AAV aggregation, AAV vectors were incubated in Formulations 1, 2, or 3 at 40°C for 2 weeks, and the increase in percentage of AAV vector aggregation was determined. As shown in FIG. 1, Formulation 1 (comprising 175 mM sodium chloride) resulted in a lower percentage increase in AAV vector aggregation than Formulation 2 (comprising 150 mM sodium chloride) or Formulation 3 (comprising 200 mM sodium chloride).

[00169] To assess the effect of trehalose and sucrose on AAV aggregation, AAV vectors were incubated in Formulation 4, 5, or 6 at 40°C for 2 weeks, and the increase in percentage AAV vector aggregation was determined. As shown in FIG. 2, Formulation 5 (comprising 3% (w/v) trehalose) resulted in a lower percentage increase in AAV vector aggregation than Formulation 4 (comprising 1% (w/v) trehalose). Formulation 6 (comprising 5% (w/v) trehalose) performed similarly to Formulation 5.

[00170] Several additional AAV vector formulations (Formulations 7-10) containing citrate or histidine buffers were generated. The components of these additional formulations are set forth in Table 2. Table 2. Components of Formulations 7-10.

[00171] Formulations 1, 7, 8, 9, and 10 were tested for their ability to maintain viral genome titer (FIGs. 3 A-3D), maintain total AAV vector purity (FIGs. 4A-4D), maintain VP 1 capsid protein integrity (FIGs. 5A-5D), and control the level of AAV vector aggregate formation (FIGs. 6A-7D), over a specified period of time at a specified temperature.

[00172] Vector genome titers were determined using droplet digital PCR (ddPCR). As shown in FIGs. 3A-3D, formulations containing histidine (Formulations 7 and 9) were able to maintain vector genome titers over time when incubated at 25°C (FIGs. 3A and 3B) and 40°C (FIGs. 3C and 3D). Of the formulations containing 1% sucrose, the histidine formulation (Formulation 7) was able to maintain vector genome titers over time when incubated at both temperatures (FIGs. 3A and 3C). Of the formulations containing 3% trehalose, the histidine formulation (Formulation 9) was able to maintain vector genome titers over time when incubated at both temperatures (FIGs. 3B and 3D). When the formulations were incubated at 40°C, formulations containing histidine (Formulations 7 and 9) were able to maintain higher vector genome titers over time when compared to formulations containing citrate and sodium phosphate (FIGs. 3C and 3D).

[00173] AAV vector purity of the formulations and the ability of the formulations to retain VP1 capsid integrity (level of VP1 capsid protein integrity measured as a function of corrected area under the curve for VP1) was determined by CE-SDS analysis. As shown in FIGs. 4A-4D, formulations containing histidine (Formulations 7 and 9) were able to maintain AAV vector purity over time when incubated at 25°C (FIGs. 4A and 4B) and 40°C (FIGs. 4C and 4D). Of the formulations containing 1% sucrose, the histidine formulation (Formulation 7) was able to maintain AAV vector purity over time when incubated at both temperatures (FIGs. 4A and 4C). Of the formulations containing 3% trehalose, the histidine formulation (Formulation 9) was able to maintain AAV vector purity over time when incubated at both temperatures (FIGs. 4B and 4D). When the formulations were incubated at 40°C, formulations containing histidine (Formulations 7 and 9) were able to maintain higher AAV vector purity over time when compared to formulations containing citrate and sodium phosphate (FIGs. 4C and 4D). As shown in FIGs. 5A-5D, formulations containing histidine (Formulations 7 and 9) were able to retain VP1 capsid protein integrity over time when incubated at 25°C (FIGs. 5A and 5B) and 40°C (FIGs. 5C and 5D). Of the formulations containing 1% sucrose, the histidine formulation (Formulation 7) was able to retain VP1 capsid protein integrity over time when incubated at both temperatures (FIGs. 5 A and 5C). Of the formulations containing 3% trehalose, the histidine formulation (Formulation 9) was able to retain VP1 capsid protein integrity over time when incubated at both temperatures (FIGs. 5B and 5D). When the formulations were incubated at 40°C, formulations containing histidine (Formulations 7 and 9) were able to retain higher VP1 capsid protein integrity over time when compared to formulations containing citrate and sodium phosphate (FIGs. 5C and 5D).

[00174] The level of AAV vector aggregates was determined as a function of the percentage of high molecular weight (BMW) species detected in each formulation using SEC. As shown in FIGs. 6A-6D, formulations containing histidine (Formulations 7 and 9) were able to better control the percentage of AAV vector aggregates formed over time when incubated at 25°C (FIGs. 6A and 6B) and 40°C (FIGs. 6C and 6D). Of the formulations containing 1% sucrose, the histidine formulation (Formulation 7) was able to better control the percentage of AAV vector aggregates formed over time when incubated at both temperatures (FIGs. 6A and 6C). Of the formulations containing 3% trehalose, the histidine formulation (Formulation 9) was able to better control the percentage of AAV vector aggregates formed over time when incubated at both temperatures (FIGs. 6B and 6D). When the formulations were incubated at 40°C, formulations containing histidine (Formulations 7 and 9) were able to better control the percentage of AAV vector aggregates formed over time when compared to formulations containing citrate and sodium phosphate (FIGs. 6C and 6D).

[00175] FIGs. 7A-7D show that the choice of sucrose or trehalose in histidine and citrate formulations has a large impact on the ability of the formulations to better control the percentage of AAV vector aggregates formed over time. Of the formulations containing histidine, the trehalose formulation (Formulation 9) was able to better control the percentage of AAV vector aggregates formed over time when incubated at 25°C (FIG. 7A) and 40°C (FIG. 7C). Of the formulations containing citrate, the trehalose formulation (Formulation 10) was able to better control the percentage of AAV vector aggregates formed over time when incubated at 25 °C (FIG. 7B) and 40°C (FIG. 7D). As such, formulations containing trehalose (Formulations 9 and 10), irrespective of the buffering agent, outperformed sucrose formulations (Formulations 7 and 8) in terms of the ability of the formulations to better control the percentage of AAV vector aggregates formed over time.

[00176] The foregoing data suggests that AAV vector formulations comprising histidine buffer and trehalose can provide improved long term AAV vector stability to relative formulations comprising phosphate or citrate buffer and sucrose.

Example 2: Long-Term Stability Studies

[00177] In order to further investigate the advantages of an AAV vector formulation containing histidine buffer and trehalose, a head-to-head comparison between Formulation 9 (comprising histidine buffer and trehalose) and Formulation 1 (comprising phosphate buffer and sucrose) was performed.

[00178] Formulations 1 and 9 incubated at various temperatures over time and AAV vector genome titers were determined using droplet digital PCR (ddPCR) (FIGs. 8A-8D). As shown in FIGs. 8A-8C, Formulations 1 and 9 were able to maintain vector genome titers to a similar extent over the time course studied, when incubated at -80°C (FIG. 8A), 5°C (FIG. 8B), and 25°C (FIG. 8C). However, when the formulations were incubated at 40°C, Formulation 9 was able to maintain higher vector genome titers compared to Formulation 1 (FIG. 8D).

[00179] The level of AAV vector aggregates in Formulations 1 and 9 incubated at various temperatures was determined as a function of the percentage of high molecular weight (HMW) species detected using SEC (FIGs. 9A-9D). As shown in FIGs. 9A-9C, the percentage of aggregates formed over the time course studied in Formulations 1 and 9 was similar when incubated at -80°C (FIG. 9A), 5°C (FIG. 9B), and 25°C (FIG. 9C). However, the percentage of aggregates formed after 2 months in Formulation 9 at 40°C was significantly less compared to Formulation 1 (FIG. 9D).

[00180] AAV vector purity of the formulations and the ability of the formulations to retain VP1 capsid protein integrity (level of VP1 capsid protein integrity measured as a function of corrected area under the curve for VP1) was determined by CE-SDS analysis of AAV vectors incubated at various temperatures over the time course studied in Formulations 1 and 9 (FIGs. 10A-1 ID). As shown in FIGs. 10A-10C, both Formulations 1 and 9 were able to maintain a similar level of AAV vector purity over time, when incubated at -80°C (FIG. 10A), 5°C (FIG. 10B), and 25°C (FIG. 10C). However, when the formulations were incubated at 40°C, Formulation 9 was able to maintain higher AAV vector purity as compared to Formulation 1 (FIG. 10D). As shown in FIGs. 11 A-l 1C, Formulations 1 and 9 were able to retain a similar level of VP1 capsid protein integrity over time, when incubated at -80°C (FIG. 11 A), 5°C (FIG. 11B), and 25°C (FIG. 11C). However, when the formulations were incubated at 40°C, Formulation 9 was able to retain a higher level of VP1 capsid protein integrity compared to Formulation 1 (FIG. 11D).

[00181] The foregoing data confirmed that AAV vector formulations comprising histidine buffer and trehalose can provide improved long term AAV vector stability relative to more traditional phosphate buffered formulations.

Example 3: Long-Term Stability Studies - Temperature

[00182] In order to assess the stability of AAV vector formulations comprising histidine buffer and trehalose, Formulation 9 was incubated at various temperatures. Vector genome titers, capsid titers, AAV aggregation, AAV vector purity, capsid protein integrity, and AAV vector potency were measured over time.

[00183] Clade F Capsid material was received in Formulation 9 as Drug Substance. The Drug Substance was 0.2 pm filtered under a Biosafety Cabinet and vialed into 0.5 mL Crystal Zenith COP vials to make the Drug Product. The Drug Product was then placed on stability at - 80°C, 5°C, and 25°C. At stability timepoints, the vials were removed from their respective storage conditions and subjected to testing of VG titers by ddPCR, capsid titers by ELISA, AAV vector aggregates by SEC, AAV vector purity by Capillary Electrophoresis (CE), VP1 content by CE, and AAV potency by relative gene expression. A subset of samples were evaluated for sub-visible particles using the Aura Halo system following USP <788> guidelines.

[00184] The level of VG titers, capsid titers, AAV % HMW, VP1 capsid protein integrity, and AAV vector purity were determined as described in Example 1. The level of AAV vector potency was determined by relative gene expression. Subvisible particulate counts were measured in terms of particle counts/mL. [00185] As shown in FIG. 12, Formulation 9 was able to maintain the level of vector genome titers (FIG. 12 A), capsid titers (FIG. 12B), AAV vector aggregates (FIG. 12C), AAV vector purity (FIG. 12D), VP1 capsid protein integrity (FIG. 12E), and AAV vector potency (FIG. 12F) overtime when incubated at -80°C, 5°C, and 25°C. Stability was maintained at -80°C for 18 months, 5°C for 12 months, and 25°C for 3 months.

[00186] As shown in FIG. 13, Formulation 9 was able to maintain and keep the level of subvisible particulate counts over time below the USP 787 Guidance of > 10 pm: < 6000 particles/mL > 25 pm: < 600 particles/mL when incubated at -80°C (FIG. 13A), 5°C (FIG. 13B) and 25°C (FIG. 13C).

[00187] The foregoing data suggests that AAV vector formulations comprising histidine buffer and trehalose can provide improved long term AAV vector stability across various thermal stresses.

Example 4: Product Stability Studies - Freeze-thaw Cycles

[00188] In order to further assess the stability of AAV vector formulations comprising histidine buffer and trehalose, Formulation 9 was incubated at various pH values and subjected to multiple freeze-thaw cycles. The level of AAV vector potency, vector genome titers, capsid titers, percentage aggregation of AAV vectors, AAV vector purity, VP1 capsid protein integrity, and AAV potency were measured.

[00189] Clade F Capsid material was received in Formulation 9 as Drug Substance. The Drug Substance was initially titered to obtain T:0 vector genome titer. Once titer was received, 0.3 mL of Drug Substance was filled into 0.5 mL Crystal Zenith COP vials under a Biosafety Cabinet (BSC). Once vials were filled, they were stoppered under BSC, capped with aluminium seal and labelled. Once sealed, one vial was subjected to testing at 5°C to obtain Ox Freeze- thaw/never frozen sample. All other samples were frozen at 80°C. Once samples were completely frozen, they were placed at 5°C to thaw until no ice was present in the sample. This process was then repeated as many times as necessary to obtain the appropriate number of freeze-thaws.

[00190] Vector genome titers, capsid titers, AAV vector aggregates, AAV vector purity, and VP1 capsid protein integrity were determined as described in Example 1. The level of AAV vector potency was determined as described in Example 3. [00191] As shown in FIG. 14, Formulation 9 was able to maintain the level of vector genome titers (FIG. 1 A), capsid titers (FIG. 14B), AAV vector aggregates (FIG. 14C), AAV vector purity (FIG. 14D), and VP1 capsid protein integrity (FIG. 14E), and AAV vector potency (FIG. 14F) across multiple freeze-thaw cycles at a range of pH values (6.3 to 8.3).

[00192] The foregoing data suggests that AAV vector formulations comprising histidine buffer and trehalose can provide improved AAV vector stability across multiple freeze-thaw cycles at a range of pH values.

Example 5: Long-Term Stability Studies - pH

[00193] In order to further assess the stability of AAV vector formulations comprising histidine buffer and trehalose, Formulation 9 was incubated at various pH values, and at different temperatures. The level of vector genome titers, capsid titers, AAV vector aggregates, AAV purity, and VP1 capsid protein integrity were measured.

[00194] This study was started by first prepping the Formulation 9 buffer (20 mM Histidine, 175 mM Sodium Chloride, 3% (w/v%) Trehalose, 0.03% Poloxamer 188). The buffers were then adjusted to the target pH (6.3, 6.8, 7.3 (control), 7.8, 8.3). Clade F Capsid material was received as Drug Substance (DS) in standard Formulation 9 buffer. DS was buffer exchanged into new Formulation 9 buffers at the different pH values by spin concentration in a centrifuge. Five separate 15 mL centrifuge filtration tubes were filled with 15 mL of DS in Formulation 9 buffer. DS concentrated until approximately 5 mL of DS remained in the centrifuge filtration tube. 10 mL of designated pH buffer was then added to appropriate filtration tubes. This process was repeated 3x to ensure thorough buffer exchange took place. A 100 pL aliquot was taken from each pH sample to measure and confirm appropriate pH was reached. Once buffer exchange was complete, the material was taken up into a 20 mL syringe with a 21G needle, then filtered through a 0.2 pm filtered into a new sterile 15 mL conical tube to create the Drug Product (DP). Each arm was then filled into 15 labeled sterile 2 mL CZ vials containing 1 mL of Drug Product each using a 1 mL pipette. Vials were then stoppered and then placed in its designated sample box and placed at appropriate storage for stability. Samples were removed from chambers at designated time points and stored at -80°C prior to analytical testing, including the level of vector genome titers, capsid titers, AAV vector aggregates, AAV vector purity, and level of AAV potency. [00195] The level of vector genome titers, capsid titers, AAV vector aggregates, AAV vector purity, and VP1 capsid protein integrity were determined as described in Example 1. The level of AAV potency was determined as described in Example 3.

[00196] As shown in FIG. 15, Formulation 9 was able to maintain the level of vector genome titers (FIGs. 15A-15B), capsid titers (FIGs. 15C-15D), AAV vector aggregates (FIGs. 15E-15F), AAV vector purity (FIGs. 15G-15H), and VP1 capsid protein integrity (FIGs. 15I-15J) at a range of pH values (6.3-8.3) at 5°C (FIGs. 15 A, C, E, G, I) and 25°C (FIGs. 15B, D, F, H, J). [00197] The foregoing data suggests that AAV vector formulations comprising histidine buffer and trehalose can provide improved long term AAV vector stability across a range of pH values and temperatures.

Example 6: High Titer Achievement

[00198] To assess the stability of AAV vector formulations comprising histidine buffer and trehalose across various AAV titers, the level of AAV vector aggregation was determined at different concentrations of a capsid drug product in Formulation 9 prepared over time.

[00199] Clade F Capsid Drug Product (DP) was received at 4.56E13 vg/mL in Formulation 9. To prepare higher concentration samples, 40 mL of DP was concentrated to 4 mL using a centrifuge filtration tubes. The 4 mL of lOx concentrated material was added to a new centrifuge tube and material was concentrated while stopping periodically to inspect the volume and material. Notes were taken at each stopping point and a 150 pL aliquot was removed and set aside for analytical testing. This was then repeated for all the following targets. Samples were submitted for analytical testing, including the level of vector genome titers, capsid titers, AAV vector aggregates, AAV vector purity, and level of AAV potency.

[00200] Vector genome titers, capsid titers, AAV vector aggregates, AAV vector purity, and VP1 capsid protein integrity were determined as described in Example 1. The level of AAV potency was determined as described in Example 3. In addition, the level of AAV vector aggregates was determined as a function of diameter on Dynamic Light Scattering (DLS) or Polydispersity Index (PDI).

[00201] As shown in FIGs. 16A-16C, Formulation 9 was able to maintain the level of AAV vector aggregates as a function of high molecular weight species (% HMW) (FIG. 16A) and as a function of diameter on DLS or PDI (FIGs. 16B-C) across a range of vector genome titers and capsid titers.

[00202] The foregoing data suggests that AAV vector formulations comprising histidine buffer and trehalose can provide improved long term AAV vector stability at high AAV titers.

Example 7: Alternative Capsid Serotypes

[00203] To assess whether the advantages of an AAV vector formulation containing histidine buffer and trehalose extend across alternative capsid serotypes, the stability of various capsid serotypes in Formulation 9 was measured.

[00204] Capsids from different Clades were received as an affinity product and buffer exchanged into Formulation 9 using centrifuge filtration tubes. Poly dispersity and average particle diameter were evaluated by Static Light Scattering (SLS) and DLS. To measure melting temperature, a thermal ramp coupled with SLS measurements at each temperature ramp was used.

[00205] As shown in FIG. 17, Formulation 9 was able to maintain stability in terms of melting temperature and AAV aggregation across multiple AAV capsid serotypes.

[00206] The foregoing data suggests that AAV vector formulations comprising histidine buffer and trehalose can provide improved long term AAV vector stability across multiple AAV capsid serotypes.
