Purpose
A recombinant adeno-associated virus serotype 2 (rAAV2) vector has been altered to carry the human MERTK (hMERTK) gene. This vector has been shown to restore vision in animal models that resemble human MERTK-associated Retinitis Pigmentosa (RP), an incurable retinal degeneration that causes severe vision loss. The proposed study is an open label, Phase I clinical trial of subretinal rAAV2-VMD2-hMERTK administration to individuals with MERTK-associated retinal disease. This trial will lead to a greater understanding of the safety and thereby potential value of gene transfer in MERTK-associated retinal disease and will have implications for other forms of retinal degenerative disease amenable to this type of intervention.

Eligibility| Ages Eligible for Study: | 14 Years to 70 Years |
| Genders Eligible for Study: | Both |
| Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- MERTK-associated retinal disease;
- VA: 20/100 or less in worse eye
- Ability to perform tests of visual and retinal function;
- Good general health based on a complete physical examination and hematology and chemistry studies performed at a pre-treatment evaluation;
- Ability to comply with research procedures;
Exclusion Criteria:
- Pre-existing eye conditions that would preclude the planned surgery or interfere with the interpretation of study endpoints or surgical complications (for example, glaucoma, corneal or lenticular opacities);
- Complicating systemic diseases (such as medical conditions causing immunosuppression) that would preclude the gene transfer, ocular surgery or known sensitivity or allergy to medications planned for use in the peri-operative period;
- Use of anti-platelet agents that may alter coagulation within 7 days prior to study agent administration;
- Use of immunosuppressive medications;
- Pregnancy or breastfeeding;
- Individuals (males and females) of childbearing potential who are unwilling to use effective contraception for 1 year following agent administration and barrier contraception for 3 months following agent administration;
- Any other condition that would prevent a subject from completing follow-up examinations during the course of the study and that, in the opinion of the investigator, makes the subject unsuitable for the study.
- Current, or recent (within the past 30 days, or 10 half lives of the drug) participation, in any other research protocol involving investigational agents or therapies.
- Recent (within past 6 months) receipt of an investigational biologic therapeutic agent.Subjects will not be excluded based on their gender, race or ethnicity.
