Material Changes and Clinical Updates
Ophthalmology Portfolio
- 4D-150 (Wet AMD & DME): Filed an IND for the Phase 2 SPECTRA trial in Diabetic Macular Edema (DME) in December 2022, with enrollment expected in Q3 2023. Initiated the randomized Phase 2 stage of the PRISM trial for Wet Age-Related Macular Degeneration (wet AMD) in January 2023.
- 4D-175 (Geographic Atrophy): Initiated preclinical development for a new candidate targeting Geographic Atrophy (GA), utilizing the R100 intravitreal vector.
- 4D-125 (XLRP) & 4D-110 (Choroideremia): Completed enrollment for Phase 1/2 trials in Q4 2022 (14 and 13 patients treated, respectively). Safety profiles remain unchanged; data updates anticipated in 2024.
Pulmonology Portfolio
- 4D-710 (Cystic Fibrosis): Treated the first patient in the high-dose cohort (2E15 vg) of the Phase 1/2 trial in December 2022 with no related adverse events through Day 28. Initiated preclinical research on combining 4D-710 with CFTR modulators.
- 4D-725 (Alpha-1 Antitrypsin Deficiency): Initiated preclinical development for a new aerosol-based candidate targeting Alpha-1 Antitrypsin Deficiency.
Rare Disease Portfolio (Fabry Disease)
- 4D-310 Interim Data: Six patients treated in two trials (U.S. and Asia-Pacific). Three instances of atypical hemolytic uremic syndrome (aHUS) occurred; all resolved within 2-4 weeks. One case required temporary hemodialysis.
- Cardiac Endpoints: Evaluable data from three U.S. patients at 12 months showed improvement in multiple endpoints, including Global Longitudinal Strain (GLS), Peak VO2, and Quality of Life (KCCQ).
- Regulatory Alignment: FDA aligned on primary endpoints for a potential pivotal trial: Peak VO2 and KCCQ, with GLS as a supportive endpoint.
Guidance, Outlook, and Risks
- Future Development of 4D-310: 4DMT does not plan to enroll additional patients in current Fabry trials. The program will be evaluated in H2 2023 after 12-month data is obtained for all six patients.
- Protocol Changes: Future 4D-310 studies will not use the current corticosteroid regimen. The company intends to evaluate a rituximab-sirolimus immune inhibition regimen to prevent aHUS under new protocols.
- Risks: The filing includes standard forward-looking statement disclaimers regarding clinical development timelines, therapeutic potential, and regulatory approvals. Specific risks are referenced in the company's most recent Form 10-Q.
Investor Verification Checklist
- Verify the safety profile and resolution timeline of the three aHUS events in the 4D-310 Fabry disease trials.
- Confirm the timeline for the initiation of the 4D-150 SPECTRA trial enrollment in Q3 2023.
- Monitor the company's progress in establishing the rituximab-sirolimus regimen for future 4D-310 studies.
- Review the 12-month cardiac endpoint data for all six 4D-310 patients when released in H2 2023.
- Assess the preclinical data readouts for the new candidates 4D-175 (GA) and 4D-725 (Alpha-1 Antitrypsin).
