Material Changes and Clinical Updates
- VBP101 Clinical Update: An abstract for the Phase 1/2a study of trem-cel (VOR33) in Acute Myeloid Leukemia (AML) patients was accepted for oral presentation at ASH. Data supports robust neutrophil engraftment and hematologic protection from Mylotarg. An updated data release is expected at the HSCT conference on November 10-11, 2023.
- CD33CART Study (PTCTC): Data from a Phase 1/2 study of autologous CD33CART (VCAR33 AUTO) in pediatric and young adult AML patients was released.
- 19 patients infused; median age 16 years.
- As of June 1, 2023, 2 of 5 (40%) evaluable patients at the highest dose level (DL4) achieved complete remission.
- Transient expansion detected in 58% of subjects across all doses and 100% at DL4.
- 4 of 19 evaluable patients experienced Grade 3 or higher cytokine release syndrome (CRS).
- VCAR33 ALLO Strategy: The Company highlighted that its allogeneic product, VCAR33 ALLO, uses the same CAR-T construct as the autologous CD33CART but utilizes T cells from healthy donors, which the Company believes offer superior stem-like phenotypes and expansion potential.
- Additional ASH Presentations:
- Single-cell analysis of molecular signatures from 28 AML patients (Oral presentation).
- Preclinical collaboration with Janssen showing synergy between CD33-deleted allografts and Janssen's immunotherapy candidate (Poster presentation).
- Trial-in-progress poster for VBP301, a Phase 1/2 study of VCAR33 ALLO in post-transplant AML patients (Poster presentation).
