Rhea-AI Summary

Vor Bio (Nasdaq: VOR) announced acceptance of two abstracts for presentation at the Keystone Symposia on Precision Genome Engineering (April 27 - May 1, 2022). The presentations will detail Vor Bio’s innovative multiplex editing capability in targeting cancer cells while preserving healthy ones, specifically for patients with acute myeloid leukemia (AML). Dr. Tirtha Chakraborty emphasized the potential of this method to minimize risks associated with traditional therapies. Vor Bio is advancing its lead program, VOR33, aimed at improving outcomes for AML patients.

Presentations showcase breadth of Vor Bio’s multiplex editing capability including base editing of human hematopoietic stem and progenitor cells (HSPCs) enabling new therapeutic approaches following transplant in patients with acute myeloid leukemia (AML)

CAMBRIDGE, Mass., April 25, 2022 (GLOBE NEWSWIRE) -- Vor Bio (Nasdaq: VOR), a clinical-stage cell and genome engineering company, today announced that two abstracts have been accepted for poster presentations at the Keystone Symposia Precision Genome Engineering meeting, held April 27 to May 1 in Keystone, Colorado.

The presentations include two posters and a workshop discussion featuring data on multiplex gene editing in human hematopoietic stem cells using various genome editing technologies. The data demonstrate how Vor Bio’s novel platform, which genetically modifies healthy donor hematopoietic stem cells (HSCs) to remove select cell surface targets, enables targeted therapies to selectively destroy cancer cells while sparing the healthy cells. This unique approach has the potential to reduce on-target toxicity, allowing new and different therapeutic approaches following transplant in patients with AML.

“As most tumor antigens are also expressed on normal blood cells, traditional multi-targeted immunotherapy increases the risk of severe cytopenia,” explained Tirtha Chakraborty, Ph.D., Vor Bio’s Chief Scientific Officer. “We are excited to present how we can potentially address this challenge with a safer approach, with minimum translocation risk, using our platform that removes two or more target antigens from the donor HSCs. This approach to transplant, coupled with targeted therapies, may enable the delivery of more efficacious and durable treatments.”

Vor Bio is advancing clinical investigation of its lead program, VOR33, an eHSC candidate for patients with AML. VOR33 consists of genome-edited hematopoietic stem and progenitor cells that have been engineered to lack the CD33 protein. It is designed to replace the standard of care in transplant settings for patients suffering from AML and potentially other blood cancers. The company’s Phase 1/2a multi-center, open-label study of VOR33, VBP101, continues to recruit participants with AML who are at risk of relapse.

Details of the abstracts and presentations times are as follows:
