Bridgewater, NJ – February 14, 2022 — Hillstream BioPharma, Inc. (Nasdaq: HILS) (“Hillstream”, 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, provided a business review along with key pipeline updates.
“We have made tremendous progress at Hillstream over the past year culminating in our successful $15 million IPO with a NASDAQ listing a month ago,” stated Randy Milby, Hillstream’s Chief Executive Officer, “Our deep roots in scientific innovation and discovery over the past decade, has allowed us to build tailor-made multi-omics ferroptotic datasets across multiple oncologic diseases to power discovery campaigns which leverage our Quatramer™ tumor-targeting platform thus bringing unprecedented therapeutics to patients suffering from devastating cancers.”
- Emerging novel mechanism of action, Ferroptosis/IMCD (Iron mediated cell death) with human proof-of-concept study showing promising efficacy in multiple solid tumors from the University of Heidelberg, Germany
- Non-clinical research using HSB-1216 in the unmet need indications of platinum-resistant small cell lung cancer as a single agent and in combination with doxorubicin in TNBC (triple negative breast cancer). 2021 American Association for Cancer Research (AACR) Abstract Number 3107: HSB-1216 A Novel Agent for the Treatment of Chemotherapy-Resistant ES-Small Cell Lung Cancer; and Abstract Number 3082: Synergistic Inhibition of TNBC cell growth by novel doxorubicin/salinomycin – encapsulated dual drug nanoparticles
- Continuing to explore additional indications including NSCLC (Non-small cell lung cancer) and AML (acute myeloid leukemia)
- The U.S. Food and Drug Administration (FDA) has granted orphan drug designation (ODD) to HSB-1216 for the treatment of small cell lung cancer. The ODD designation provides seven years of market exclusivity post approval.
- AACR E-poster Number 492- (Abstract 803) in 2020 A Novel QUATRA Acquisition of a ferroptosis inducer portfolio with related global patents, non-clinical data, other filings and know-how. The licensed products are various novel small molecules with increased efficacy against a sub-group of solid tumors including breast, pancreatic and prostate. The increased potency of these compounds along with a wider therapeutic index makes them attractive as backups to HSB-1216.
- AACR E-Poster Number 491 – (Abstract 738) in 2020 – Encapsulation of the stem cell inhibitor Salinomycin in novel QUATRAMER sustained injectable suspension (HSB-1216) for the treatment of small cell lung cancer
- AACR Abstract Number 3107 in 2021: HSB-1216 A Novel Agent for the Treatment of Chemotherapy-Resistant ES-Small Cell Lung Cancer
- Continuing IND enabling studies to launch human studies last in 2022
QUATRAMER™ Tumor Targeting Platform
- Novel tumor targeting platform for small molecules, biologics (including ADNCs, ADCs and scFv’s)
- QUATRAMER is our key platform, poised to enter the Immuno-oncology (IO) space with a novel technology that we believe may provide a non-viral tumor specific delivery vehicle of cytokines with high efficacy in tumors with too narrow a therapeutic index for clinical feasibility, including TNF-alpha and others
- Collaboration with the Ardena Group, a world-class Contract Development and Manufacturing Organization (CDMO to secure manufacturing feasibility and capacity for QUATRAMER portfolio. The Ardena Group aligns with our strategy of partnering with the best collaborators.
World-Class Scientific Advisory Board
- Expansion of our Scientific Advisory Board (SAB) with the addition of Scott J. Dixon, Ph.D., Associate Professor, Biology, Stanford University and Faculty Fellow of Stanford’s ChEM-H initiative and Member, Stanford Cancer Institute.

About Hillstream BioPharma Inc.
Hillstream BioPharma, Inc. is 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. Hillstream’s most advanced candidate is HSB-1216, an IMCD modulator, targeting a variety of solid tumors. The active drug in HSB-1216 was found to be efficacious in a clinical pilot study in Germany in devastating cancers, including triple negative breast cancer and epithelial carcinomas. Hillstream intends to start a clinical study with HSB-1216 in 2022 to expand upon the existing early clinical proof-of-concept. Hillstream uses Quatramer™, our proprietary tumor targeting platform, to enhance the uptake of HSB-1216 in the tumor microenvironment with an extended duration of action and minimal off-target toxicity. In addition, Trident Artificial Intelligence, Hillstream’s artificial intelligence precision medicine platform, is used to identify biomarkers in our clinical programs to target a specific patient segment most likely to benefit.
