Study Endpoints

Primary Endpoints

Proportion of Participants With Subretinal Surgical Delivery of OpRegen to Target Regions
3 months post-surgery
Incidence and Severity of Procedure-related Adverse Events (AEs) at 3 Months Following Surgery
3 months post-surgery
Percentage of Participants With Treatment Emergent Adverse Events
From study start till 12 months following last subject dosed, plus up to 90 days (up to approximately 6.5 years)

An adverse event is any untoward medical occurrence in a subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events. The AE's were graded using National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) v 3.0.

Frequently asked questions about OpRegen

What is OpRegen used for?

OpRegen is an investigational cell therapy being developed for age-related macular degeneration and geographic atrophy, a late-stage form of the disease. It is delivered by subretinal injection and is currently in clinical trials for patients aged 50 years and older with these conditions.

Who makes OpRegen?

OpRegen is being developed by Roche Holding AG, which trades over the counter under the ticker RHHBY. The company is conducting clinical trials of OpRegen in the United States and Israel for geographic atrophy secondary to age-related macular degeneration.

What phase is OpRegen in?

OpRegen is in clinical development. One trial is in Phase 1 and another is in Phase 2. Both are ongoing, with the Phase 2 study actively recruiting participants. OpRegen is not approved by the FDA and remains investigational.

What clinical trials is OpRegen in?

OpRegen is being studied in two trials. NCT02286089 is a Phase 1 safety and efficacy study in advanced dry-form age-related macular degeneration, with 24 participants. NCT05626114 is a Phase 2 study in geographic atrophy secondary to age-related macular degeneration, with 60 participants, and includes an adaptive optics retinal imaging substudy.

Is OpRegen a monoclonal antibody?

No, OpRegen is not a monoclonal antibody. It is a cell therapy administered by subretinal injection. It is being evaluated for its safety and activity in treating geographic atrophy, a form of age-related macular degeneration.

Is OpRegen the same as GAlette?

OpRegen is associated with the GAlette study, which is the title of a Phase 2 clinical trial evaluating OpRegen in participants with geographic atrophy secondary to age-related macular degeneration. GAlette is the study name, not an alternative name for the drug itself.
