Hillstream BioPharma licenses technology for proprietary antibody conjugates

Hillstream BioPharma signed an exclusive agreement with Applied Biomedical Science Institute – ABSI – to license technology for human antibodies targeting novel HER2 and HER3 Conformational Epitopes. The goal is to develop proprietary multi-format biologics, including bi-specific antibodies, and antibody drug conjugates. The HER2/HER3 binding ADC is targeted to have a high drug-to-antibody ratio which should increase the anti-tumoral efficacy with an enhanced bystander killing effect. Hillstream intends to combat drug resistant cancers such as HER2-positive metastatic breast cancer, gastric cancer, lung cancer and ovarian cancer. The Applied Biomedical Science Institute has developed technology to target novel functional epitopes of the cancer targets HER2 and HER3. ABSI has granted Hillstream an exclusive license agreement, and Hillstream will have the opportunity to develop HER2 and HER3 antibodies, including multi-specific, ADC, and Quatramer-based therapeutics utilizing portions of these antibodies.
