Our Platform Aspect Ratio 1200 384

Our Platform

We have built a proprietary platform for the treatment of Acute Myeloid Leukemia (AML) and other blood cancers.

We have built a technology platform to realize our vision that allows for selective cancer targeting with highly potent targeted therapies by leveraging our expertise and recent advances in stem cell biology and genome engineering.

Our approach is in stark contrast to conventional approaches that have focused solely on developing the therapeutic and have faced clinical limitations due to toxicities. The key components of our proprietary platform are stem cell biology and manufacturing expertise, genome engineering to HSCs, and unlocking the potential of targeted therapies.

Stem Cell Biology Aspect Ratio 600 400

Leveraging stem cell biology and manufacturing expertise

We have built an extensive understanding of the biology of HSCs to enable our shielded transplants to retain their cellular viability and functionality during manipulation. In addition, we have built process development expertise centered around HSCs, enabling us to process these cells quickly, precisely, reproducibly, and efficiently for patients. We are continuing to develop our in-house clinical GMP manufacturing capabilities and facilities to further allow us to leverage our expertise and maintain strategic control over the manufacturing process.

Platform Genome Engineering Aspect Ratio 600 400

Applying genome
engineering to HSCs

Recent developments in genome engineering allow permanent changes to DNA in cells and all their progeny. We have assembled a team with extensive experience in applying genome engineering technologies to HSCs, which display distinct DNA repair mechanisms compared to many other cell types. We possess expertise in a variety of genome engineering technologies including CRISPR-Cas9, CRISPR analog enzymes and base editing, and we are capable of multiplex editing using a variety of techniques, all with the objective of creating various shielded transplants.

Platform Car T Aspect Ratio 600 400

Unlocking the potential of
targeted therapies

We believe our shielded transplants are a potential solution to the lack of tumor-specific targets and can enable selective cancer targeting. We are directly developing CAR-T therapies, which we believe is the most potent form of targeted therapies available. Our CAR-T product candidates are uniquely generated from prior healthy transplant donors where these cells are healthy, more stemlike compared to other cell sources, and exactly matched to the patient since the patient’s blood and immune system was previously reconstituted by the transplant donor. Our objective is to create highly potent CAR-T therapies that are designed to strongly proliferate and persist in patients, in order to drive prolonged relapse-free survival or induce cures in patients.

Our goal is to replace the patient’s HSCs with next-generation, treatment-resistant eHSCs that unlock the potential of highly potent targeted therapies by leveraging our new treatment platform and CAR-T cells, stem cell biology, and genome engineering expertise.

Current Challenge with Standard of Care Transplants for AML

Stem Cells from Healthy Donor

Patient receives unmodified stem cells (from healthy donor) that engraft and rebuild the immune system.

Re-emerging Cancer Cells

Watchful waiting is the only option. In half of patients, the cancer returns, and the 2 year survival rate is <20%.

How the Trem-cel Treatment System Works

Vor Bio's Shielded Stem Cells

Patient receives stem cells (from healthy donor) that have been modified using gene editing to remove CD33 (trem-cel). The shielded stem cells engraft and rebuild the immune system.

Cells targeted with ADC and CAR-T therapy and shielded cells

A targeted therapy, such as an ADC or CAR-T, can now be used to kill any residual cancer cells. The shielded stem cells persist and remain unaffected.
