Material Changes and Clinical Data
The Company announced nine-month data from the ongoing Phase 1/2 clinical trial (MGT009) of AAV-RPGR. Key findings include:
- Retinal Sensitivity: Six out of seven patients in the low (n=3) and intermediate (n=4) dose cohorts demonstrated improvement or stability in retinal sensitivity in the treated eye. Improvements were sustained or further improved compared to the six-month analysis.
- Vision-Guided Mobility: Five of six patients demonstrated improvement in walk time at low light levels (1, 4, or 16 lux). Significant improvement was observed between treated and untreated eyes at 1 lux (-16.1 seconds) and 4 lux (-3.71 seconds).
- High Dose Cohort: No improvements in retinal sensitivity were observed at six months. Perimetry assessment was not carried out at nine months due to a protocol revision.
- Safety: AAV-RPGR is well-tolerated with no dose-limiting events. Inflammation observed in the high dose cohort was effectively managed with an extended steroid protocol.
Guidance, Outlook, and Risks
Outlook and Next Steps:
- The low and intermediate doses are being evaluated in the ongoing randomized, controlled expansion portion of the Phase 1/2 study, which completed enrollment in the first half of 2020.
- The Company and Janssen plan to advance AAV-RPGR into a Phase 3 pivotal study called the Lumeos clinical trial.
- Forward-looking statements are subject to risks including the inability to achieve profitability, acquire capital, or successfully execute clinical trials.
- Specific risks include the impact of the COVID-19 pandemic on trial enrollment and timing, failure to obtain regulatory approval, manufacturing issues, and competition.
- Early data may not predict eventual outcomes.
Investor Verification Checklist
- Verify the specific statistical significance and confidence intervals for the retinal sensitivity and mobility data in the full press release (Exhibit 99.1).
- Confirm the timeline and enrollment status of the randomized, controlled expansion portion of the Phase 1/2 study.
- Review the detailed protocol revision regarding the high dose cohort and its implications for future dosing strategies.
- Assess the Company's cash runway and capital requirements in the most recent 10-Q or 10-K, as this 8-K does not contain financial data.
- Monitor updates on the planned Phase 3 Lumeos clinical trial initiation.
