"We are very excited with these promising results from our study of a new treatment combination for patients with this most highly aggressive form of breast cancer, triple-negative breast cancer," said study principal investigator Shipra Gandhi, MD, Associate Professor of Oncology and staff physician in the Department of Medicine at Roswell Comprehensive Cancer Center. "Because this initial study was in a small number of patients, it will be important to validate these findings in a larger study."

For more information on the data reported, please visit Roswell Park’s website to read its press release titled, "Roswell Park Clinical Trial Points Toward Promising New Therapy for Most Aggressive Type of Breast Cancer."

AIM CEO Thomas K. Equels stated: "The results of this pilot study suggest that the Ampligen-containing chemokine modulation regimen is capable of modifying the tumor microenvironment and releasing cytokines that attract killer T-cells into the early-stage triple-negative breast cancer tumor. These data are similar to those we have seen with Ampligen previously in late-stage TNBC, advanced recurrent ovarian cancer and pancreatic cancer. We look forward to collaborating with Roswell Park as this study advances to Phase 2. We believe in the power of Ampligen to work in conjunction with a variety of chemotherapy regimens and/or immune checkpoint inhibitors."

"This transformative transaction, which marks the completion of our strategic review process, accelerates our evolution into becoming a leading immunology company with both small and large molecule drugs," said Dr. Neal Walker, Interim CEO and Chair of the Board of Directors of Aclaris. "Despite recent advances with anti-TSLP and anti-IL4R therapies, there remains substantial unmet need for more effective and convenient treatment options. BSI-045B’s compelling Phase 2a proof-of-concept data in atopic dermatitis, together with BSI-502’s dual-targeting approach, complement our existing ITK inhibitor portfolio, resulting in a pipeline of differentiated assets that targets multiple high-value indications. In addition, the proceeds from the private placement financing announced this morning bolsters our balance sheet and provides us with enhanced financial flexibility to support our strategic growth while maintaining our cash runway into 2028."

In a completed Phase 2a, single-arm, proof-of-concept trial in the United States in 22 patients with moderate to severe atopic dermatitis, BSI-045B was observed to have a pharmacodynamic, safety and efficacy profile that could position it as a potential best-in-class therapy. BSI-045B is also being advanced in multiple Phase 2 studies in China by Biosion’s regional partner, Chia Tai Tianqing Pharmaceutical Group, Co., Ltd. (CTTQ), targeting both severe asthma and chronic rhinosinusitis with nasal polyps, accelerating the potential to show proof-of-concept across additional indications.

"This strategic transaction brings together Biosion’s and Aclaris’ innovative programs with Aclaris’ development capabilities in immunology," said James Loerop, Chief Business Officer of Aclaris. "With our expanded portfolio, we have created a diversified pipeline of strategic opportunities across various immunologic and respiratory indications."

Biosion is a global biotechnology company that has built a pipeline of innovative biologics through its internally derived proprietary technologies. "Our proprietary antibody discovery platforms have enabled us to rapidly identify and optimize novel antibodies with exceptional potency and selectivity," said Mingjiu Chen, Ph.D., Founder and CEO of Biosion. "BSI-045B and BSI-502 demonstrate the power of our discovery capabilities in generating potential first and best-in-class therapeutics."

About BSI-045B

BSI-045B is a humanized anti-thymic stromal lymphopoietin (TSLP) monoclonal antibody that specifically binds to human TSLP, blocking its interaction with the receptor complex and disrupting signal transduction. This mechanism prevents immune cells targeted by TSLP from releasing proinflammatory cytokines. BSI-045B is currently in clinical development, and its safety and efficacy have not been evaluated by regulatory authorities.

About BSI-502

BSI-502 is a humanized anti-TSLP and anti-interleukin 4 receptor (IL4R) bispecific antibody that blocks both the upstream TSLP receptor signal transduction and downstream IL4R activation thereby inhibiting this central proinflammatory pathway. BSI-502 is currently in pre-clinical development, and its safety and efficacy have not been evaluated by regulatory authorities.

Conference Call and Webcast

Management will conduct a conference call at 8:30 AM ET today to discuss the Biosion transaction and a corporate update.

On November 18, 2024 Cancer Targeted Technology (CTT), a privately-held Seattle-based biotechnology firm focusing on cancer diagnostics and therapeutics, reported that the National Cancer Institute awarded the Phase I portion ($400K) of the fast track Phase I/II ($2.4M) Small Business Innovation Research (SBIR) grant to develop a new drug to treat metastatic prostate cancer (Press release, Cancer Targeted Technology, NOV 18, 2024, View Source [SID1234648491]). The grant focuses on a promising new prodrug, CTT2274, that targets Prostate-Specific Membrane Antigen (PSMA) on prostate cancer and is designed to release a toxic drug, MMAE, within the cell that takes up the prodrug. PSMA is over-expressed on prostate cancer and expression increases as the cancer metastasizes and becomes castrate resistant. CTT’s unique phosphoramidate-based agents, bind irreversibly to PSMA and unlike other agents targeting PSMA, this distinctive mode of binding enhances uptake and internalization by tumor cells, leading to increased accumulation of the therapeutic payload and improved efficacy.

Studies to date using CTT2274 treatment of mice bearing human prostate tumors have shown remission of tumor growth and an overall increase in survival. In addition, because of the prodrug release within the tumor cells, safety of the drug, at doses that are effective at inhibiting or reversing tumor growth, is excellent. In the Phase I portion of the grant, to be completed in Q2 2025, CTT will conduct additional non-clinical efficacy studies and manufacturing optimization. In Phase II of the grant, to be completed in Q2, 2026, CTT will conduct additional manufacturing and safety assessments necessary to advance CTT2274 to an Investigational New Drug (IND) application. These IND studies will support the initial clinical trial in metastatic prostate cancer planned for 2026.

"CTT2274 has a unique structure and linker that maximizes tumor uptake and allows for release of the chemotherapeutic drug only within the tumor cell thus minimizing potential side effects from the chemotherapy. No other prodrug like this is being developed for prostate cancer and CTT2274 holds great promise as a future treatment for men suffering from prostate cancer." stated Dr. Beatrice Langton-Webster, CEO of CTT and Principal Investigator on the grant.
