Hillstream BioPharma Signs an Exclusive Option Agreement to Advance Next-Generation Anti-MUC1-C Agents for Drug Resistant Cancers

Development expected to capitalize upon tumor targeting Quatramers

MUC1-C could be effective against a number of drug resistant cancers such as metastatic triple negative breast cancer (TNBC), small cell lung cancer (SCLC), merkel cell carcinoma (MCC) and neuroendocrine prostate cancer (NEPC)

BRIDGEWATER, N.J., Jan. 31, 2023 (GLOBE NEWSWIRE) -- Hillstream BioPharma, Inc. (Nasdaq: HILS) (“Hillstream”, or the “Company”), a biotechnology company developing novel therapeutic candidates targeting ferroptosis, an emerging new anti-cancer mechanism resulting in iron mediated cell death for drug resistant and devastating cancers, today announced signing an exclusive option agreement with Dana-Farber Cancer Institute to license technology targeting the MUC1-C oncoprotein.

The MUC1 gene was identified by Dr. Donald Kufe, Distinguished Physician and Researcher at Dana-Farber and based on its overexpression in human cancers. Dr. Kufe’s long-standing work has supported the premise that prolonged activation of MUC1-C in settings of chronic inflammation promotes cancer.

Dr. Kufe has demonstrated that MUC1-C is necessary for multiple hallmarks of the cancer cell, including (i) the persister cell (PC) state, (ii) drug resistance, (iii) immunosuppression, and (iv) poor clinical outcomes. Importantly, he has found a marked MUC1-C dependency for cancer stem cells (CSCs) derived from highly aggressive TNBCs, SCLCs, MCCs and NEPCs. Based on these findings, MUC1-C has emerged as an exceptional target for cancer treatment with agents developed in the Kufe laboratory.

Dana-Farber has granted under an exclusive option agreement to Hillstream Biopharma Inc., certain of its proprietary technology which if converted to an exclusive license agreement, will allow Hillstream to develop anti-MUC1-C antibodies to selectively deliver Hillstream’s Quatramer-based lead candidate HSB-1216 targeting CSC by the induction of ferroptosis. This approach combining HSB-1216 with conjugation to MUC1-C antibodies is highly synergistic for the elimination of CSCs, which is needed for long term responses and cures.

“We look forward to this unique opportunity to work with Dr. Kufe and Dana-Farber,” said Randy Milby, CEO of Hillstream. “This agreement allows Hillstream to leverage our Quatramer platform to advance anti-MUC1-C agents targeting CSCs for the treatment of highly aggressive tumors, which represents a major unmet need for patients.”

About Hillstream BioPharma, Inc.
Hillstream BioPharma, Inc. is a biotechnology company developing novel therapeutic candidates against drug-resistant and devastating cancers. Hillstream’s most advanced candidate, HSB-1216, expected to enter clinical trials in 2023, targets ferroptosis, an emerging new anti-cancer mechanism resulting in iron mediated cell death (IMCD) for drug resistant and devastating cancers. Hillstream’s most advanced candidate is HSB-1216, an IMCD modulator, whose active drug was found to be efficacious in a clinical pilot study in Germany in drug resistant tumors, including triple negative breast cancer and epithelial carcinomas. Hillstream intends to initiate IND discussions with the FDA in first half of 2023. Hillstream uses Quatramer™, a proprietary tumor targeting platform which extends duration of action and minimizes off-target toxicity, with HSB-1216 as well as biologics, mRNA, peptides and other modalities in the tumor microenvironment. Quatrabody™ conjugates immuno-oncology targets with greater binding affinity than approved therapies. Hillstream Quatramers with novel biologics developed against proprietary undruggable epitopes of PD-1 and other validated will enter the rapidly growing immuno-oncology therapeutics market leading with HSB-1940, targeting PD-1, followed by additional targets including PD-L1, HER-2, TROP-2 and now MUC1-C.  For more information, please visit: www.hillstreambio.com.
