CAMBRIDGE, Mass., March 20, 2024 (GLOBE NEWSWIRE) -- Vor Bio (Nasdaq: VOR), a clinical-stage cell and genome engineering company, today reported financial results for the three-month period and full year ended December 31, 2023, and provided a business update.

“We are very pleased with the foundational progress we made in 2023.

Corporate Updates

Multiple patients expected to be dosed with VCAR33ALLO in the first half of 2024; initial data anticipated in second half of 2024

  • VBP301, a Phase 1/2, multicenter, open-label, first-in-human study of VCAR33ALLO, is a transplant donor-derived anti-CD33 CAR-T cell therapy for patients with AML who have relapsed following a standard-of-care or trem-cel transplant. The first patient was dosed in January 2024, and multiple patients are expected to be dosed in the first half of 2024. We anticipate initial data in the second half of 2024.

  • The U.S. Food & Drug Administration (FDA) has granted Fast Track Designation and Orphan Drug Designation to VCAR33ALLO. The FDA Fast Track process aims to facilitate the development and expedite the review of drugs that treat serious conditions and fill an unmet medical need. Orphan Drug Designation entitles companies to development incentives including tax credits for clinical testing, prescription drug user fee exemptions and seven-year marketing exclusivity in the event of regulatory approval.

VCAR33ALLO is manufactured from lymphocytes collected from the patient’s original transplant donor, generating a CAR-T cell therapy that is exactly matched to the recipient’s engrafted blood system. By using healthy transplant donor cells as the starting material to produce VCAR33ALLO, the CAR-T cells have a more stem-like phenotype, leading to greater potential for expansion, persistence, and anti-leukemia activity compared to a product derived from a patient’s own lymphocytes.

VBP101 clinical trial of trem-cel enrolling steadily, with the next data readout expected in the second half of 2024

  • Dose escalation of Mylotarg to 1.0 mg/m2 has commenced with multiple patients now treated.

  • Patients receiving a trem-cel transplant who become measurable residual disease (MRD) positive or relapse have the option to receive induction-course Mylotarg or VCAR33ALLO.

  • The Company expects to report further engraftment and protection data from the VBP101 clinical trial in the second half of 2024.

  • The latest data update from VBP101, the Phase 1/2a clinical study of trem-cel, was presented at the ASH Annual Meeting on December 10, 2023, showing primary neutrophil engraftment in all eight patients and hematologic protection from acute Mylotarg toxicity through repeat doses.
