CAMBRIDGE, Mass., Nov. 10, 2022 (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, 2022 and provided a business update. 

"We continue to actively enroll patients in our lead clinical trial, VBP101 and look forward to sharing important initial clinical proof of concept data from this study by year end," said Dr. Robert Ang, Vor Bio's President and Chief Executive Officer. "We are excited that our new in-house clinical manufacturing facility is now operational and our IND for VCAR33 is on-track for submission in the first half of 2023. We remain fully focused on our mission to transform the standard of care for patients with blood cancers."

Corporate Highlights

Eyal C. Attar, M.D. appointed as Chief Medical Officer. Eyal C. Attar, M.D., has joined Vor Bio as Chief Medical Office. Dr. Attar brings more than 20 years of demonstrated clinical experience including extensive background in hematologic malignancies, with previous roles as a clinician, bench researcher and in clinical development.

Initiated in-house clinical manufacturing at Cambridge, MA headquarters. The new facility provides critical operational and strategic control of manufacturing enabling more efficient development of the Company's novel cell and genome engineering platform and pipeline of engineered hematopoietic stem cell (eHSC) and CAR-T product candidates. The facility will initially manufacture clinical supply to support the IND for VCAR33^ALLO with plans to technology transfer the production of VOR33 to the site.

Successfully demonstrated potential of base and sequential multiplex editing of HSCs for next-generation acute myeloid leukemia (AML) treatment. Preclinical data presented at the European Society of Gene & Cell Therapy (ESGCT) 29th Congress, October 11-14, demonstrated that multiplex deletion of myeloid antigens CD33 and CLL-1 or CD33 and CD123 in human HSCs resulted in long-term engraftment and persistence of editing. These data showed that Vor Bio's novel platform enabled efficient removal of multiple target antigens from HSCs while managing off-target and translocation events.

Screening and initial validation of single domain CAR binders for CAR-T cell therapies. Research presented at the Society for Immunotherapy of Cancer (SITC), November 8-12, identified novel CAR binders that may yield promising candidates for future in vitro and in vivo screening of primary CAR-T cell therapies against AML.

VOR33 and VCAR33 granted ATMP status by EMA. VOR33 and VCAR33 received Advanced Therapy Medicinal Product (ATMP) classification by the European Medicines Agency (EMA). ATMPs are medicines for human use that are based on genes, tissues or cells that offer groundbreaking new opportunities for the treatment of disease and injury. ATMP classification confers certain benefits to company sponsors, designed to expedite the research, development, and Marketing Authorisation of these products.

Program Updates

VOR33: VOR33, is a genome-edited 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. VOR33 has the potential to enable powerful targeted therapies in the post-transplant setting including CD33-targeted CAR-Ts.

• The Company is on track to share initial clinical proof-of-concept data in Q4 of 2022 from VBP101, its Phase 1/2a multicenter, open-label, first-in-human study of VOR33 in patients with AML who are at risk of relapse. Successful engraftment would provide important validation for Vor Bio's platform.
• The clinical trial continues to recruit patients with nine trial sites currently active.

VCAR33 Programs: The VCAR33 programs are chimeric antigen receptor T (CAR-T) cell therapy candidates designed to target CD33, a clinically validated target for AML.

• VCAR33^ALLO uses allogeneic healthy donor-derived cells and is Vor Bio's lead VCAR33 program in which the Company plans to submit an investigational new drug (IND) application in the first half of 2023 to support a Phase 1/2 clinical trial for patients with relapsed/refractory AML.
• VCAR33^AUTO uses autologous cells from each patient and is being studied in an ongoing Phase 1/2 clinical trial sponsored by the National Marrow Donor Program (NMDP) in young adult and pediatric patients with relapsed/refractory AML in a bridge-to-transplant study. The Company no longer expects data from this study to be reported in 2022 and timing of data release is dependent on the investigators conducting the trial.

Upcoming Milestones

• Initial VOR33 clinical data on-track for Q4 of 2022
• VOR33 engraftment and hematologic protection data updates expected in 2023
• VCAR33^ALLO IND submission expected in the first half of 2023
  
  

Third Quarter 2022 Financial Results

• Cash Position: Cash, cash equivalents and investments were $136.1 million as of September 30, 2022, which is anticipated to fund operations into the first quarter of 2024.
  
  
  
  
• Research & Development (R&D) Expenses: R&D expenses for the third quarter of 2022 were $16.9 million, compared to $12.9 million for the third quarter of 2021. The increase in R&D expense was primarily due to increased personnel expenses including an increase in stock compensation expense, facility costs from our laboratory and cGMP manufacturing facility expansion and clinical and manufacturing expenses as a result of the ongoing VOR33 clinical trial.
  
  
  
  
• General & Administrative (G&A) Expenses: G&A expenses for the third quarter of 2022 were $7.2 million, compared to $5.7 million for the third quarter of 2021. The increase in G&A expense was primarily due to increased personnel expenses, including an increase in stock compensation expense.
  
  
  
  
• Net Loss: Net loss for the third quarter of 2022 was $23.8 million, compared to $18.6 million for the third quarter of 2021.
