Company Engages Top-Tier Contract Research Organization

SAN DIEGO, Sept. 13, 2022 /PRNewswire/ -- Regen BioPharma, Inc. (OTC PINK: RGBP) and (OTC PINK: RGBPP) announced today initiation of a series of phased experiments to begin the process of moving its CAR-T cell de-differentiation approach through pre-clinical validation. CAR-T cells are T cells (the lymphoid cells of the body that kill tumors) isolated from a cancer patient that have been modified by expressing a chimeric antigen receptor (CAR) which is specific for the patient's tumor.

While CAR-T cells are effective at treating certain lymphomas and leukemias, solid tumors such as liver, breast and colon remain resistant to CAR-T therapies for several reasons. One reason is "T cell exhaustion", a term that means the T cells that are initially recruited to the tumor to kill it end up losing their effectiveness. The company believes that NR2F6, a checkpoint that puts the brakes on T cell activity, is a key player in the T Cell exhaustion phenomenon. Inhibiting NR2F6 is expected to prevent these T cells from becoming dysfunctional.

The Company has engaged the contract research organization, ProMab Biotechnologies, Inc. of Richmond, California, to embark on a series of experiments using the Company's proprietary shRNA NR2F6-inhibiting technology to validate this approach.

"We are extremely excited to be using our cutting-edge genetic approach to create long-lasting CAR-T cells," says David Koos, Chairman and CEO of the Company. "By partnering with a well-qualified organization such as ProMab Biotechnologies, Inc., we expect to quickly move this program forward to the clinic."
