- Company to present trem-cel + Mylotarg clinical data update at American Society of Hematology (ASH) 2024 annual meeting
- Han Choi, M.D., LL.M, seasoned healthcare institutional investor, appointed as Chief Financial Officer
CAMBRIDGE, Mass., Nov. 07, 2024 (GLOBE NEWSWIRE) -- Vor Bio (Nasdaq: VOR), a clinical-stage cell and genome engineering company, today reported financial results for the three-month period ended September 30, 2024, and provided a corporate update.
“We are pleased with our operational and clinical execution this quarter and look forward to sharing additional clinical data since our September data update at the ASH annual meeting in December,” said Dr. Robert Ang, Vor Bio’s President and Chief Executive Officer.
Corporate Updates
Trem-cel + Mylotarg (VBP101) Clinical Trial
- 25 patients have been dosed with trem-cel and 6 patients have now received the third dose level of Mylotarg at 2 mg/m2.
- On September 5, 2024, the Company provided a clinical update on 18 patients treated with trem-cel in the VBP101 study. The data demonstrated:
- Reliable engraftment, robust platelet recovery, and high CD33 editing efficiency with full myeloid chimerism at Day 28.
- Shielding of the blood system, with maintained neutrophil and platelet counts across multiple Mylotarg doses of 0.5, 1, and 2 mg/m2.
- Broadened therapeutic index for Mylotarg with drug exposure represented by AUC which is related to efficacy, consistent with labeled Mylotarg doses, and with maximal concentrations, measured by Cmax and related to veno-occlusive disease, well below known toxic range.
- Early evidence suggesting patient benefit as measured by relapse-free survival when compared to published high-risk AML comparators1.
- The Company plans to share a further clinical data update in a poster presentation at the ASH Annual Meeting on Sunday, December 8, from 6-8pm PT. (Poster Session 616. Acute Myeloid Leukemias: Investigational Drug and Cellular Therapies. Publication number 2873). The poster will be made available on Vor Bio’s website when the ASH embargo lifts at 9am PT on the day of the presentation and the Company plans to host a webcast to review the data on Monday, December 9th at 5am PT/8am ET.
Trem-cel is a shielded transplant in development for patients with acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS), in which healthy transplant donor cells are genetically engineered by removing CD33, with the potential to shield healthy cells and enable targeted therapies post-transplant such as Mylotarg and CAR-T therapy.
VCAR33ALLO (VBP301) Clinical Trial
- Dosing is ongoing in the VBP301 study with continued strong enrollment.
- On September 5, 2024, the Company announced encouraging in vivo CAR-T expansion data from three patients treated to date, all at the lowest dose of 1 x 106 CAR+ cells/kg.
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.
Preclinical Research Updates
VADC45
In September 2024, the Company announced a new preclinical asset, VADC45, which has several potential opportunities in oncology, gene therapy, and autoimmune disorders. VADC45 is an antibody-drug conjugate (ADC) designed to target the CD45 protein, a well-validated target for a wide variety of blood cancers with clinical poof of concept. The linker-payload used in VADC45 has also been clinically validated. Vor Bio is currently progressing IND-enabling studies to enable future Phase 1 studies.
Preclinical data presentations further validate Vor Bio’s robust platform
ESGCT 2024
In October 2024, the Company presented preclinical data at the European Society of Gene and Cell Therapy Congress on the development and characterization of its novel CD33/CLL-1-directed CAR-T approach in AML.
ASH 2024
Additional analyses from the most comprehensive single cell AML atlas known to date (more than 400,000 cells from 26 AML patients and 10 healthy donors) were accepted for presentation at the ASH 2024 annual meeting in December. These data provide an unprecedented view of AML immunophenotypic heterogeneity, both across patients and within patients across clinical timepoints.
Abstract Title: Multimodal Atlas of Paired Diagnosis and Relapse AML Reveals Surface Antigens for Multi-Specific Immunotherapy
Format: Poster presentation
Session Name: Acute Myeloid Leukemias: Biomarkers and Molecular Markers in Diagnosis and Prognosis
Session date and time: Saturday, Dec 7, 5:30-7:30pm PT
New Chief Financial Officer appointed
Han Choi, M.D., LL.M., was appointed as Vor Bio’s new Chief Financial Officer. Dr. Choi brings more than 25 years of experience in investment management, business development, and corporate strategy within the pharmaceutical and biotechnology sectors to Vor Bio. His extensive expertise in forming corporate partnerships, managing complex transactions, and developing capital markets strategies will be pivotal as the Company advances its clinical pipeline and strengthens its leadership in cell and genome engineering.
Upcoming Milestones
- Trem-cel + Mylotarg clinical data update planned at ASH 2024 annual meeting
Third Quarter 2024 Financial Results
- Cash Position: Cash, cash equivalents and marketable securities were $62.8 million as of September 30, 2024, which is projected to fund operations into the second half of 2025.
- Research & Development (R&D) Expenses: R&D expenses for the third quarter of 2024 were $21.8 million, compared to $27.6 million for the third quarter of 2023. The decrease of $5.8 million was due to a decrease in license payments, preclinical expenses, and manufacturing starting materials, offset in part by an increase in clinical trial costs to support our trem-cel and VCAR33ALLO programs.
- General & Administrative (G&A) Expenses: G&A expenses for the third quarter of 2024 were $6.7 million, compared to $7.7 million for the third quarter of 2023. The decrease of $1.0 million was primarily due to a decrease in professional fees and stock-based compensation expense.
- Net Loss: Net loss for the third quarter of 2024 was $27.6 million, compared to $33.2 million for the third quarter of 2023.
