Vor Bio Reports First Quarter 2023 Financial Results and Provides Company Update

• VBP101 clinical data update planned at European Hematology Association (EHA) 2023
• VCAR33^ALLO IND submission on-track for 1H 2023

CAMBRIDGE, Mass., May 11, 2023 (GLOBE NEWSWIRE) -- Vor Bio (Nasdaq: VOR), a clinical-stage cell and genome engineering company, today reported financial results for the three-month period ended March 31, 2023, and provided a business update. 

“We are pleased with the progress we made during the quarter. Our focus continues to be on actively enrolling and treating additional patients in our VBP101 study and submission of the VCAR33^ALLO IND, which is on-track for the first half of 2023,” said Dr. Robert Ang, Vor Bio’s President and Chief Executive Officer. “We look forward to sharing additional data from VBP101 at EHA in June, initiating enrollment in VBP301, and treating our first patient with VCAR33^ALLO once the IND clears.”

Corporate Updates

Trem-cel clinical trial (VBP101) continues to actively enroll patients; next data update expected at EHA 2023

• The company plans to provide further clinical updates on patients treated in the VBP101 study at the EHA2023 Congress, June 9-11, 2023, in Frankfurt, Germany, presented by Dr. Guenther Koehne, MD, PhD, Deputy Director and Chief of Blood & Marrow Transplant and Hematologic Oncology at Miami Cancer Institute of Baptist Health South Florida.
• The study continues to see strong investigator enthusiasm with robust enrollment.
• Additional trem-cel engraftment and hematologic protection data updates are expected by year-end 2023.
  

Trem-cel is a genome-edited allogeneic hematopoietic stem cell transplant (HSCT) that is lacking the CD33 protein. It is designed to replace standard of care transplants for patients suffering from acute myeloid leukemia (AML) and potentially other blood cancers. Trem-cel has the potential to enable powerful targeted therapies in the post-transplant setting including Mylotarg and CD33-targeted CAR-Ts.

VCAR33^ALLO IND on-track for 1H 2023 submission to U.S. Food & Drug Administration (FDA)

• VCAR33^ALLO is planned to be studied in the VBP301 clinical trial, which will focus on patients who have relapsed following allogeneic stem cell transplant where T cells harvested from the original donor are used as starting material for the drug product.
• The majority of the planned clinical trial sites for VBP301 overlap with VBP101, which should optimize clinical trial site initiation and enrollment.

VCAR33^ALLO is a T-cell therapy derived from allogeneic healthy donors using a chimeric antigen receptor (CAR) specifically binding to CD33.

cGMP qualification of in-house clinical manufacturing facility nearly complete

Current Good Manufacturing Practices (cGMP) qualification activities at the Company’s new in-house manufacturing facility have nearly completed, and the Company is ready to initiate clinical manufacturing of VCAR33^ALLO upon IND clearance. The Company plans to commence trem-cel production at the in-house facility in 2023.    

Upcoming Milestones

• VBP101 data update at EHA in June 2023
• VCAR33^ALLO IND submission expected in 1H 2023
• Additional trem-cel engraftment and hematologic protection data updates expected by year-end 2023
• In-house manufacturing of trem-cel operational by year-end 2023    

First Quarter 2023 Financial Results

• Cash Position: Cash, cash equivalents and marketable securities were $210.2 million as of March 31, 2023, which is projected to fund operations into the first quarter of 2025.
  

• Research & Development (R&D) Expenses: R&D expenses for the first quarter of 2023 were $21.9 million, compared to $15.3 million for the first quarter of 2022. The increase in R&D expenses was primarily due to an increase in clinical, manufacturing and consulting expenses as a result of the ongoing trem-cel clinical trial and the development of the VCAR33 program, an increase in personnel expenses, and an increase in facility costs from the Company’s laboratory and cGMP manufacturing facility expansion.
  

• General & Administrative (G&A) Expenses: G&A expenses for the first quarter of 2023 were $8.5 million, compared to $7.5 million for the first quarter of 2022. The increase in G&A expense was primarily due to increased personnel expenses, including an increase in stock-based compensation expense, and an increase in professional fees.
  

• Net Loss: Net loss for the first quarter of 2023 was $28.4 million, compared to $22.7 million for the first quarter of 2022.
