AAV compositions
The AAV compositions comprising an AAV and a buffer. These AAV compositions are appropriate for us in intracerebroventricular (ICV) and intraparenchymal (IPA) administration, as well as other routes of administration and can be provided in frozen, liquid or potentially freeze dried (lyophilized) state.
1 . A storage stable aqueous composition comprising an adeno-associated virus (AAV) vector and a buffer formulation consisting of:
(a) about 30 mM to about 50 mM of L-histidine;
(b) about 100 mM to about 160 mM of sodium chloride;
(c) about 0.0001% (w/w) to about 0.01% (w/w) of polysorbate 80 (PS80); and
(d) water,
wherein the composition does not comprise sugar, sugar alcohol, or a combination thereof,
wherein the composition has a pH of 6.9 to 7.4, and
wherein the AAV vector has a titer that is stable when stored at a temperature range of about −60° C. to about 5° C. for at least 6 months.
2 . The aqueous composition of claim 1 , wherein the composition has a pH of about 7.0.
3 . The aqueous composition of claim 1 , wherein the PS80 is about 0.0005% to about 0.006% w/w.
4 . The aqueous composition of claim 1 , comprising the AAV vector and the buffer formulation consisting of: (a) about 50 mM of L-histidine, (b) about 154 mM of sodium chloride, (c) about 0.003% w/w of PS80, and (d) water.
5 . The aqueous composition of claim 1 , comprising: the AAV vector and the buffer formulation consisting of (a) about 30 mM of L-histidine; (b) about 154 mM of NaCl; (c) about 0.001% w/w to about 0.005% w/w of polysorbate 80 (PS80); and (d) water.
6 . The aqueous composition of claim 1 , wherein the AAV vector is an AAV1, AAV2, AAV3, AAV4, AAV5, AAV6, AAV7, AAV8, AAV9, or AAV10 vector.
7 . The aqueous composition of claim 1 , wherein the AAV vector is genetically and/or chemically modified.
8 . A lyophilized storage stable composition, wherein the lyophilized storage stable composition is dehydrated composition of the aqueous composition of claim 1 .
9 . The aqueous composition of claim 1 , wherein the composition has an osmolality of 200 to 320 mOsmol/kg.
10 . The aqueous composition of claim 1 , wherein the AAV vector has a titer that is stable when stored at a temperature range of about −20° C. to about 4° C. for at least 6 months.
