- Trem-cel and VCAR33ALLO clinical trial data expected in the second half of 2024
- VCAR33ALLO granted Fast Track and Orphan Drug Designation by
U.S. Food & Drug Administration - Cash runway extends into second half of 2025
“We are very pleased with the foundational progress we made in 2023. Building on this, we expect 2024 to be an exciting year in which we demonstrate the Vor Bio approach to be instrumental in reducing the disease burden of AML, a devastating cancer where we desperately need effective treatment options,” said Dr.
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.
Trem-cel is a shielded transplant in development for patients with AML, in which healthy transplant donor cells are genetically engineered by removing CD33, with the potential to enable targeted therapies such as Mylotarg and CD33-targeted CAR-T therapy post-transplant, while avoiding on-target toxicities.
Continued progress on dual-targeted CAR-T and multiplex engineering approach
The Company continues to make progress with a dual-specific CAR-T targeting CD33 and CLL-1, two of the most promising antigens in AML. This is being paired with a hematopoietic stem cell (HSC) multiplex engineering approach, which could allow removal or modification of these two genes. The Company has demonstrated in vitro proof of concept for this approach.
IND-enabling work is progressing for the Company’s dual-specific CAR-T with key in vivo proof-of-concept experiments underway.
Upcoming Milestones
- Trem-cel clinical data update expected in the second half of 2024
- VCAR33ALLO clinical data update expected in the second half of 2024
Fourth Quarter and Full Year 2023 Financial Results
- Cash Position: Cash, cash equivalents and marketable securities were
$137.2 million as ofDecember 31, 2023 , which is projected to fund operations into the second half of 2025. - Research & Development (R&D) Expenses: R&D expenses for the fourth quarter of 2023 were
$20.9 million , compared to$17.1 million for the fourth quarter of 2022, and for the year endedDecember 31, 2023 , were$94.3 million , compared to$64.6 million for the year endedDecember 31, 2022 . The increase in R&D expenses was attributable primarily to an increase in clinical trial, manufacturing and personnel expenses, and the execution of our non-exclusive license agreement with Editas Medicine. - General & Administrative (G&A) Expenses: G&A expenses for the fourth quarter of 2023 were
$7.2 million , compared to$7.7 million for the fourth quarter of 2022, and for the year endedDecember 31, 2023 , were$31.7 million , compared to$28.9 million for the year endedDecember 31, 2022 . The increase in G&A expenses was primarily attributable to an increase in personnel expenses, including an increase in share-based compensation expense. - Net Loss: Net loss for the fourth quarter of 2023 was
$26.3 million , compared to$23.9 million for the fourth quarter of 2022, and for the year endedDecember 31, 2023 , was$117.9 million , compared to$92.1 million for the year endedDecember 31, 2022 .
