Phase I Trial of Gene Vector to Patients With Retinal Disease Due to RPE65 Mutations
Bu çalışma, RPE65 genindeki mutasyonlara bağlı retina hastalığı olan hastalarda deneysel bir gen tedavisini (rAAV2-CBSB-hRPE65) incelemektedir. Çalışmaya, iki adet hastalık yapıcı RPE65 mutasyonu taşıyan, Leber konjenital amorozisi (Leber congenital amaurosis) tanısı olan ve görme işlevi ileri derecede bozulmuş hastalar katılabilmiştir. University of Pennsylvania tarafından yürütülen çalışma Faz 1 aşamasında yürütülmüş; şu an katılımcı almamakta ancak devam etmektedir (active, not recruiting).

Inclusion Criteria: * RPE65-associated retinal disease (two disease-causing RPE65 mutations); * Clinical diagnosis of Leber congenital amaurosis (LCA)/early-onset retinal degeneration (EORD) and of severely impaired visual and retinal function, and best corrected visual acuity of 20/40 or worse in the study eye; * Ability to perform tests of visual and retinal function; * Visible photoreceptor layer on a standard OCT scan; * Good general health; * Ability to comply with research procedures; * Specific for Cohorts 1, 2 and 4: 18 years of age and older; * Specific for Cohorts 3 and 5: Between 8 and 17 years of age, inclusive. Exclusion Criteria: * AAV antibody titers greater than two standard deviations above normal at baseline; * Humoral immune deficiency as evidenced by low tetanus toxoid IgG antibody titers; * Pre-existing eye conditions that would preclude the planned surgery or interfere with the interpretation of study endpoints or surgical complications; * Complicating systemic diseases; * 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; * Any condition that would prevent a subject from completing follow-up examinations during the course of the study; * Any condition that makes the subject unsuitable for the study; * Current, or recent participation, in any other research protocol involving investigational agents or therapies; * Recent receipt of an investigational biologic therapeutic agent.
