Material Changes and Clinical Data Highlights
The filing reports interim data as of a July 15, 2022 data-cut date for nine evaluable patients treated with ADI-001:
- Patient Demographics: Median age of 62 years; 67% male. Patients were heavily pretreated with a median of four prior therapies and a median International Prognostic Index (IPI) score of four.
- Dosing: Patients were treated at three dose levels (30 million, 100 million, and 300 million CAR+ cells). Two patients at the highest dose level received a second course of treatment.
- Efficacy: The overall response rate (ORR) was 78% (7/9 patients), and the complete response (CR) rate was 78%. Among four patients with prior autologous CD19 CAR T therapies, the ORR and CR rate was 100%.
- Durability: Of the seven patients who achieved CR, four remained in CR with follow-up ranging from 1.2 to 8.8 months. Two patients progressed, and one died of unrelated causes while in remission.
- Safety: No Grade 3 or higher Cytokine Release Syndrome (CRS) or Immune Effector Cell-Associated Neurotoxicity Syndrome (ICANS) events were observed. Two patients experienced CRS (one Grade 1, one Grade 2). No graft versus host disease or dose-limiting toxicities were reported.
Guidance, Outlook, and Risks
