TREATMENT OF AMD USING AAV2 VARIANT WITH AFLIBERCEPT
The present disclosure provides pharmaceutical compositions and methods thereof for the treatment of age-related macular degeneration (AMD) in a subject by administering intravitreally a pharmaceutical composition adapted for gene therapy, comprising a vector having a nucleic acid sequence that encodes aflibercept.
1 : A method of treating an eye condition or disease, the method comprising administering a unit dose of a pharmaceutical composition by intravitreal injection to an eye of a primate subject in need thereof, wherein the pharmaceutical composition comprises:
(a) a rAAV2 variant comprising an amino acid sequence LGETTRP (SEQ ID NO: 4) inserted between positions 587 and 588 of capsid protein VP1, and a nucleic acid sequence encoding a polypeptide comprising a sequence having at least 95% homology to aflibercept, and
(b) a pharmaceutically acceptable excipient.
2 : The method of claim 1 , wherein the eye condition or disease is neovascular (wet) age-related macular degeneration (AMD), macular edema following retinal vein occlusion, diabetic macular edema (DME), or diabetic retinopathy associated with DME.
3 : The method of claim 1 , wherein the eye condition or disease is choroidal neovascularization or wet AMD.
4 : The method of claim 1 , wherein the unit dose is between 1E12 to 1E13 vector genomes.
5 : The method of claim 1 , wherein the unit dose is between 2E12 to 6E12 vector genomes.
6 : The method of claim 1 , wherein the unit dose is in a volume that is not more than 100 μL.
7 : The method of claim 6 , wherein the unit dose is in a volume that is not more than 50 μL.
8 . (canceled)
9 : The method of claim 1 , wherein the subject is a human.
10 : The method of claim 1 , wherein the subject is responsive to aflibercept.
11 : The method of claim 1 , wherein the subject has been pre-treated with aflibercept.
12 : The method of claim 1 , wherein the administering by intravitreal injection occurs not more than once in at least 2 years.
13 : The method of claim 12 , wherein the administering by intravitreal injection occurs not more than once in at least 5 years.
14 : The method of claim 1 , wherein the administering by intravitreal injection is a one-time administration.
15 : The method of claim 1 , wherein the pharmaceutical composition is a suspension.
16 : The method of claim 15 , further comprising agitating the suspension to ensure even distribution of the suspension prior to the administering step.
17 : The method of claim 1 , further comprising warming the pharmaceutical composition to room temperature prior to the administering step.
18 - 46 . (canceled)
47 : The method of claim 1 , wherein the polypeptide encoded by the nucleic acid comprises a sequence having 100% homology to alibercept.
