Sub-retinal Transplantation of hESC Derived RPE(MA09-hRPE)Cells in Patients With Stargardt's Macular Dystrophy

Completed · Phase 1/Phase 2

Conditions studied: Stargardt's Macular Dystrophy

In brief

This is a safety and tolerability trial to evaluate the effect of subretinal injection of human embryonic stem cell derived retinal pigment epithelium cells in patients with Stargardt's Macular Dystrophy (SMD).

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Adult male or female over 18 years of age.
• Clinical diagnosis of advanced SMD.
• If known, the patient's genotype will be recorded in the medical history, if unknown, patient will allow for the submission of a sample for genotyping.Clinical findings consistent with SMD.
• The visual acuity of the eye to receive the transplant will be no better than 20/400. The visual acuity of the eye in the better vision cohort to receive the transplant will be no better than 20/100.
• The visual acuity of the eye that is not to receive the transplant will be no better than 20/400 for the worse vision patients and no worse than 20/100 for the better vision patients.
• Peripheral visual field constriction documented on standard kinetic visual field testing.
• Electrophysiological findings consistent with SMD.
• Medically suitable to undergo vitrectomy and subretinal injection.
• Medically suitable for general anesthesia or waking sedation, if needed.
• Medically suitable for transplantation of an embryonic stem cell line:
• Normal serum chemistry (sequential multi-channel analyzer 20 [SMA- 20]) and hematology (complete blood count [CBC], prothrombin time [PT], and activated partial thromboplastin time [aPTT]) screening tests.
• Negative urine screen for drugs of abuse.
• Negative human immunodeficiency virus (HIV), hepatitis B (HBV), hepatitis C (HCV) serologies.
• No history of malignancy,with the exception of successfully treated basal cell or squamous cell carcinoma of the skin.
• Negative cancer screening within previous 6 months:
• complete history \& physical examination;
• dermatological screening exam for malignant lesions;
• negative fecal occult blood test \& if over age 50 years, negative colonoscopy within previous 7 years;
• negative chest roentgenogram (CXR);
• normal CBC \& manual differential;
• negative urinalysis (U/A);
• normal thyroid exam;
• if male, normal testicular examination; if over age 40, digital rectal examination (DRE) and prostate specific antigen (PSA);
• if female, normal pelvic examination with Papanicolaou smear; and
• if female, normal clinical breast exam and if 40 years of age or older, negative mammogram.

You may not qualify if…

• History of malignancy,with the exception of successfully treated basal cell or squamous cell carcinoma of the skin.
• History of myocardial infarction in previous 12 months.
• History of diabetes mellitus.
• Any immunodeficiency.
• Any current immunosuppressive therapy other than intermittent or low dose corticosteroids.
• Serologic evidence of infection with Hepatitis B, Hepatitis C, or HIV.
• Current participation in any other clinical trial.
• Participation within previous 6 months in any clinical trial of a drug by ocular or systemic administration.
• Any other sight-threatening ocular disease.
• Any chronic ocular medications.
• Any history of retinal vascular disease (compromised blood-retinal barrier.
• Glaucoma.
• Uveitis or other intraocular inflammatory disease.
• Significant lens opacities or other media opacity.
• Ocular lens removal within previous 3 months.
• If female, pregnancy or lactation.
• Any other medical condition, which, in the Investigator's judgment, will interfere with the patient's ability to comply with the protocol, compromises patient safety, or interferes with the interpretation of the study results.
