Hillstream BioPharma Signs Exclusive Option Agreement with Applied Biomedical Science Institute (ABSI) to License Technology for HER2 and HER3 to be Developed for Potential Treatments Against Drug Resistant Cancers Including HER2-Positive Metastatic Breast Cancer, Gastric Cancer, Lung Cancer and Ovarian Cancer
Hillstream BioPharma, Inc. (Nasdaq: HILS) has entered an exclusive option agreement with Applied Biomedical Science Institute (ABSI) to license HER2 and HER3 Conformational Domain Bridging Epitopes technology. This collaboration aims to develop proprietary multi-format biologics targeting drug-resistant cancers, including HER2-positive metastatic breast cancer and gastric cancer. The agreement allows Hillstream to create innovative therapeutics such as bispecific antibodies, antibody drug conjugates (ADCs), and CAR-T therapies. The company's pipeline includes HSB-1216, expected to enter clinical trials in 2023, focusing on an emerging anti-cancer mechanism called ferroptosis.
- Exclusive agreement with ABSI for HER2 and HER3 technology enhances Hillstream's antibody platform.
- Potential development of innovative treatments for drug-resistant cancers may address significant unmet medical needs.
- HSB-1216, targeting ferroptosis, is expected to enter clinical trials, showing promise in treating triple-negative breast cancer.
- Reliance on the success of clinical trials, which carry inherent risks and uncertainties.
- Potential delays or discontinuation of clinical trials could affect the timeline for bringing products to market.
HER2 and HER3 Conformational Domain Bridging Epitopes in Antibodies via an Exclusive Option Allows Hillstream BioPharma to Develop Proprietary Multi-format Biologics (bispecific, ADC, CAR-T) against Drug Resistant Breast and Gastric Cancers
Anti-HER2 and Anti-HER3 monoclonal antibodies could be effective against a number of epithelial tumors including HER2-positive metastatic breast cancer, gastric cancer, lung cancer and ovarian cancer
Antibody CDRs against HER2 and HER3 Conformational Domain Bridging Epitopes can be used in multiple formats including bi- and tri-specific antibodies, ADCs (antibody drug conjugates), CAR-T and CAR-NKs, as well as in Quatramers™ and Quatrabodies™
BRIDGEWATER, N.J., Feb. 13, 2023 (GLOBE NEWSWIRE) -- Hillstream BioPharma, Inc. (Nasdaq: HILS) ("Hillstream" or the "Company"), a biotechnology company developing therapeutic candidates targeting drug resistant and devastating cancers using ferroptosis, an emerging new anti-cancer mechanism resulting in iron mediated cell death, and immuno-oncology targeted novel biologics, today announced signing an exclusive option agreement with Applied Biomedical Science Institute (ABSI) to license technology for HER2 and HER3 Conformational Domain Bridging Epitopes in human monoclonal antibodies to develop proprietary multi-format biologics (bi- and tri-specific antibodies, ADCs (antibody drug conjugates), CAR-T and CAR-NKs, in Quatramers and Quatrabodies) against drug resistant cancers including HER2-positive metastatic breast cancer, gastric cancer, lung cancer and ovarian cancer .
The ErbB family of cell surface proteins are some of the most well-known and validated oncology drug targets including ErbB2 or HER2 (human epidermal growth factor receptor) and Erb3 or HER3. The family of antibodies and biologics against HER2 starting with HERCEPTIN® (trastuzumab) approved in 1998 for breast cancer, one of the first few anti-cancer antibodies, as well as PERJETA®, KADCYLA® and PHESGO® totaled
The Applied Biomedical Science Institute has developed technology to target unique functional epitopes of the cancer targets HER2 and HER3. Monoclonal antibodies being developed at ABSI are unique from the currently approved anti-HER2 antibodies. ABSI has granted under an exclusive option agreement to Hillstream, certain of its proprietary technology which if converted to an exclusive license agreement, will allow Hillstream to develop HER2 and HER3 antibodies, including multi-specific and Quatramer- based therapeutics incorporating portions of the antibodies.
“We look forward to this unique opportunity to work with Dr. Smider and the Applied Biomedical Science Institute,” said Randy Milby, CEO of Hillstream. “This agreement allows Hillstream to build our antibody platform to advance our immune-oncology biologic pipeline with HER2 and HER3 agents targeting highly aggressive drug resistant metastatic tumors, representing 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 and TROP-2.
