Next trem-cel clinical data update expected by year-end 2023
VCAR33ALLO IND cleared by U.S. FDA; Rapidly activating sites toward study initiation
Secured non-exclusive license to Cas9 gene-edited HSCs
CAMBRIDGE, Mass., Aug. 10, 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 June 30, 2023, and provided a business update.
“We are pleased with the progress we have made during the quarter. The recent clearance of our IND for VCAR33ALLO represents a significant step forward in our vision of creating a Treatment System for acute myeloid leukemia which may enable more potent and durable responses in the post-transplant setting without on-target toxicity,” said Dr. Robert Ang, Vor Bio’s President and Chief Executive Officer. “We also look forward to sharing further engraftment and Mylotarg hematologic protection data from our VBP101 clinical study by year-end.”
Corporate Updates
Trem-cel clinical trial (VBP101) continues to actively enroll patients; next data update expected by year-end 2023
Clinical data presented at the European Hematology Association 2023 meeting by Dr. Guenther Koehne, a clinical investigator for the VBP101 study, showed primary neutrophil engraftment in the first five patients treated and demonstrated consistent manufacturing of trem-cel with high CD33 editing efficiency.
The Company plans to provide its next VBP101 clinical update by year-end 2023. The data set is expected to include engraftment data for additional patients receiving a trem-cel transplant and further Mylotarg™ hematologic protection data.
Following a planned safety review of initial patients receiving trem-cel, the enrollment stagger requiring engraftment prior to transplanting subsequent patients was removed and is expected to increase the pace of enrollment.
Trem-cel is a genome-edited allogeneic hematopoietic cell transplant (HCT) that is lacking the CD33 protein. It is designed to replace standard of care transplants for patients suffering from 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.
VCAR33ALLO IND cleared by the U.S. Food & Drug Administration (FDA)
The U.S. FDA has cleared the Company’s Investigational New Drug (IND) application for VCAR33ALLO, a T-cell therapy derived from allogeneic healthy donors using a chimeric antigen receptor (CAR) specifically binding to CD33.
The Phase 1/2 VBP301 clinical trial will enroll patients who have relapsed following allogeneic stem cell transplant, which uses lymphoid cells harvested from the original donor as starting material for the drug product.
Many of the planned clinical trial sites for VBP301 overlap with VBP101, which should optimize clinical trial site initiation.
The protocol allows for patients who have received a trem-cel transplant on the VBP101 study to enroll onto VBP301 and receive VCAR33ALLO. This may provide valuable early insights into the potential of the Company’s Treatment System combining trem-cel and VCAR33ALLO to enable a more potent therapy and durable responses post-transplant.
In-house clinical manufacturing of VCAR33ALLO ready to be initiated; First engineering runs in preparation for Trem-cel tech transfer completed
The Company recently completed Current Good Manufacturing Practices (cGMP) qualification activities at its new in-house manufacturing facility. The site can now initiate clinical manufacturing of VCAR33ALLO for the VBP301 clinical trial.
The first engineering runs required in preparation for tech transfer of trem-cel to Vor Bio’s in-house facility have been completed. The Company is on-track to commence in-house trem-cel manufacturing in 2023 and will continue to leverage a third-party to provide manufacturing redundancy.
Secured worldwide non-exclusive license to Cas9 gene-edited HSCs from Editas Medicine, Inc.
The company secured a worldwide non-exclusive license from Editas Medicine for ex-vivo Cas9 gene-edited HSC therapies for the treatment and/or prevention of hematological malignancies. The license provides access to key intellectual property for the continued development and commercialization of edited HSCs including trem-cel (VOR33), with the option to elect additional product candidate targets within the next five years.
Upcoming Milestones
VBP101 clinical data update including engraftment data for additional patients and further Mylotarg hematologic protection expected by year-end 2023
In-house manufacturing of trem-cel operational by year-end 2023
Second Quarter 2023 Financial Results
Cash Position: Cash, cash equivalents and marketable securities were $186.9 million as of June 30, 2023, which is projected to fund operations into the first quarter of 2025.
Research & Development (R&D) Expenses: R&D expenses for the second quarter of 2023 were $23.9 million, compared to $15.3 million for the second quarter of 2022. The increase in R&D expenses was primarily due to an increase in clinical, manufacturing and consulting expenses of $4.7 million as a result of the ongoing trem-cel clinical trial and the development of our VCAR33 programs, an increase in personnel expenses of $2.5 million, and an increase in facility costs from our laboratory and cGMP manufacturing facility expansion of $1.4 million.
General & Administrative (G&A) Expenses: G&A expenses for the second quarter of 2023 were $8.3 million, compared to $6.5 million for the second quarter of 2022. The increase in G&A expense was primarily due to an increase in personnel costs of $1.4 million, including an increase in stock-based compensation expense of $1.0 million, and an increase in facilities and other expenses of $0.4 million.
Net Loss: Net loss for the second quarter of 2023 was $30.0 million, compared to $21.7 million for the second quarter of 2022.
