Vor Bio Winds Down Operations Amid Funding Challenges, Lays Off 95% of Staff
Cambridge, Massachusetts-based cell engineering company Vor Bio has announced a significant restructuring, including the cessation of all clinical and manufacturing activities and the layoff of 95% of its workforce. The decision comes as the company, co-founded by oncologist and Pulitzer Prize-winning author Siddhartha Mukherjee, faces a challenging funding environment and reassesses its pipeline of early-stage cell therapies for acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS).
Strategic Shift and Workforce Reduction
Vor Bio's board of directors has determined that the company does not see a viable path forward for its current pipeline, based on available clinical data. As a result, the company will immediately halt all ongoing clinical trials and manufacturing operations. In a move to conserve resources, Vor Bio is laying off approximately 151 of its 159 full-time employees, retaining only eight staff members to manage regulatory compliance, financial reporting, and the wind-down of operations.
The company estimates it will incur $10.9 million in costs related to the workforce reduction. As of the end of 2024, Vor Bio reported $91.9 million in cash, cash equivalents, and marketable securities on hand.
Exploring Exit Options
In light of these developments, Vor Bio is actively exploring strategic alternatives to maximize shareholder value. Potential options under consideration include:
- Licensing or selling its assets
- Executing a merger
- Selling the company outright
- Other strategic actions
The company has not provided a specific timeline for this process and has stated it does not intend to disclose further developments until a specific action is approved by the board of directors.
Recent Funding and Pipeline Overview
The announcement comes just months after Vor Bio secured $55.6 million through a PIPE financing arrangement led by LinkedIn co-founder Reid Hoffman in December 2024. This funding was intended to advance the company's pipeline of cell therapy treatments for AML and MDS.
Vor Bio's pipeline included:
- Trem-cel: An engineered cell transplant for AML and MDS (Phase I/II trial)
- VCAR33: A CAR T treatment for AML (Phase I/II trial)
- Antibody-drug conjugates and cell transplants for AML (preclinical discovery and IND-enabling studies)
With the cessation of clinical activities, the future of these programs remains uncertain as the company explores potential exit strategies.
