GARDian Trial Summary

This trial is researching a possible treatment for a rare eye condition. Safety and effectiveness will be assessed.

Who is the study for?
This clinical trial is for individuals aged 18-65 with Stargardt Disease, specifically those who have a vision acuity of 50 letters or less on the ETDRS chart. Participants must have confirmed genetic mutations in ABCA4 and evidence of macular lesions consistent with the disease. They should also have some remaining retinal layer detectable by OCT imaging.Check my eligibility
What is being tested?
The study tests OCU410ST's safety and effectiveness for treating Stargardt Disease. It's a two-phase trial involving up to 42 participants across multiple centers, aiming to see how well this treatment works and if it's safe.See study design
What are the potential side effects?
Since this is an early phase trial (Phase 1/2), specific side effects are not yet fully known but will be closely monitored throughout the study to ensure patient safety.

9Treatment groups
Experimental Treatment
Active Control
Group I: Experimental: Phase1 Dose Escalation- Medium Dose (7.5×10E10 vg/mL):Experimental Treatment1 Intervention
Medium Dose (7.5×10E10 vg/mL): Subjects will receive a subretinal injection of OCU410ST in the Medium dose concentration.
Group II: Experimental: Phase1 Dose Escalation- Low Dose (3.75×10E10 vg/mL):Experimental Treatment1 Intervention
Low Dose (3.75×10E10 vg/mL): Subjects will receive a subretinal injection of 200 µL of OCU410ST in the low dose concentration.
Group III: Experimental: Phase1 Dose Escalation- High Dose (2.25×10E11 vg/mL):Experimental Treatment1 Intervention
High Dose (2.25×10E11 vg/mL): Subjects will receive a subretinal injection of OCU410ST in the high dose concentration.
Group IV: Experimental: Phase 2 Dose Expansion: Dose 2 from Phase 1-Randomized Pediatric ArmExperimental Treatment1 Intervention
Subjects will receive a subretinal injection of OCU410ST with Lower Dose than Maximum tolerated dose (MTD) from Phase 1
Group V: Experimental: Phase 2 Dose Expansion: Dose 2 from Phase 1-Randomized Adult ArmExperimental Treatment1 Intervention
Subjects will receive a subretinal injection of OCU410ST with Lower Dose than Maximum tolerated dose (MTD) from Phase 1

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Is the admission of elderly individuals into this trial permissible?

"According to the parameters of eligibility, applicants must be no younger than 6 and not surpassing 65 years old."

Answered by AI

To what extent is this experiment being tested on participants?

"Affirmative. The trial's listing on clinicaltrials.gov indicates that it is presently inviting eligible participants to take part in the research, which was first advertised on August 25th 2023 and last updated September 6th 2023. 42 individuals are sought from two distinct locations."

Answered by AI

What is the central hypothesis of this clinical investigation?

"The primary evaluation criterion for this study, which will be monitored over a 12 month period from screening to administrations of OCU410ST, is ophthalmic safety as measured by BCVA (Best Corrected Visual Acuity). Secondary objectives include tracking changes in serum chemistry such as electrolytes and renal functions, humoral and cellular immune response after administration of the drug, and systemic circulation shedding of AAV vectors."

Answered by AI

Is there a possibility for enrolment in this experiment currently?

"Affirmative, the information hosted by clinicaltrials.gov confirms that this trial is currently recruiting participants. The study was made public on August 25th 2023 and subsequently revised on September 6th of the same year. 42 patients need to be enrolled in total between 2 different sites involved in the research."

Answered by AI

Is eligibility extended to me so I can be part of this trial?

"This trial is recruiting 42 patients with Stargardt disease, aged 6-65. To be eligible to participate in this study one must have a minimum of 300 microns diameter of atrophy as depicted by fundus autofluorescence imaging and no more than 18mm2 total lesion area (equivalent to 5 disc areas), BCVA of 50 ETDRS letters or less, confirmed presence of two pathogenic mutations in the ABCA4 gene or one pathogenic mutation plus typical clinical presentation/phenotypic presentation of ABCA4 retinopathy in both eyes, detectable outer nuclear layer (ONL) determined by SD-"
