Precision Biologics Announces the United States Patent and Trademark Office (USPTO) has granted a Patent for its Lead Monoclonal Antibody, NEO-201, For the Treatment of Human Carcinomas

BETHESDA, Md., Oct. 2, 2023 /PRNewswire/ -- Precision Biologics, Inc. ("Precision"), a clinical-stage immunotherapy and targeted oncology company, announced today that on September 26, 2023, the USPTO granted a patent for its lead clinical asset, NEO-201, which is currently being tested in Phase 2 human Clinical Trials in the US.

NEO-201 is a humanized IgG1 monoclonal antibody with multiple mechanisms of action. It has been shown previously to kill cancer cells expressing its target (truncated glycans) which is expressed in numerous cancers; however, it does not bind to most normal tissues. In addition, NEO-201 binds to immune suppressor cells, including regulatory T cells (Tregs) and granulocytic myeloid-derived suppressor cells (gMDSCs), which are thought to diminish the efficacy of cancer immunotherapy.

In the Phase I clinical trial, NEO-201 was found to reduce immune suppressive cells that may be responsible in diminishing cancer-killing activity for checkpoint inhibitors. Based on the safety and activity of NEO-201 in its Phase I completed study, a Phase II study is currently enrolling patients with metastatic Non-Small Cell Lung Cancer (NSCLC), Head and Neck Cancer, Endometrial Cancer and Cervical Cancer, whose disease has previously progressed through prior checkpoint inhibitor therapy (including prior Keytruda.) (https://clinicaltrials.gov/ct2/show/NCT03476681)  This ongoing Phase 2 trial is testing to see if combining NEO-201 with Keytruda can reactivate the effectiveness of checkpoint inhibitors when they no longer work. 

Data from the ongoing Phase 2 trial was recently presented at CRI-ENCI-AACR 7th International Cancer Immunotherapy Conference Sept 22, 2023, Milan, Italy. This data demonstrated that NEO-201 reduces the quantity of regulatory T cells in PBMCs of cancer patients and this reduction is associated with stabilization of disease. (click here).

Additional data regarding the effects of NEO-201 on reducing gMDSCs will be presented at the upcoming SITC Annual Meeting in San Diego in early November.
