Welcome to our dedicated page for Atossa Therapeutics news (Ticker: ATOS), a resource for investors and traders seeking the latest updates and insights on Atossa Therapeutics stock.
Overview
Atossa Therapeutics Inc (ATOS) is a clinical stage biopharmaceutical company that develops and markets innovative medicines, laboratory tests, and therapeutic delivery platforms focused on addressing unmet medical needs in oncology. With a primary emphasis on women’s breast health and breast cancer, the company is dedicated to advancing novel drug candidates and precision-targeted delivery systems, employing cutting-edge approaches such as selective estrogen receptor modulation and intraductal microcatheter technology.
Core Therapeutic Focus
The company’s flagship asset, (Z)-endoxifen, exemplifies its commitment to tackling critical challenges in breast cancer treatment. (Z)-endoxifen is a potent selective estrogen receptor modulator (SERM) that not only inhibits estrogen receptor activity but also facilitates its degradation. This dual action is strategically designed to address cases where resistance to traditional hormonal therapies exists, thus filling a significant therapeutic gap in oncology. Additionally, the formulation of (Z)-endoxifen is developed as an oral medication that bypasses the liver metabolism and gastric degradation issues, ensuring optimal bioavailability at therapeutic concentrations.
Innovative Drug Delivery Platforms
Beyond its core drug candidates, Atossa Therapeutics is also pioneering advanced delivery mechanisms to enhance therapeutic efficacy. The development of intraductal microcatheter technology represents a novel approach to deliver therapies directly to the site of breast cancer, thereby improving the targeting of treatments such as hormonal therapies, immunotherapies, and chimeric antigen receptor T-cell therapies. This targeted delivery strategy not only heightens the precision of treatment but also has the potential to reduce systemic side effects, contributing to an overall improved patient experience.
Clinical Development and Research Programs
Atossa’s development pipeline is robust, with multiple Phase 2 trials designed to evaluate the effectiveness of (Z)-endoxifen in diverse patient populations, including women with measurable breast density and those diagnosed with ductal carcinoma in situ. The company’s research initiatives extend to combination therapies, where (Z)-endoxifen is studied alongside other agents such as cyclin-dependent kinase (CDK) inhibitors, further broadening the therapeutic paradigm in breast cancer treatment. These programs underscore the company’s strategic emphasis on targeted oncology, employing rigorous clinical methods to substantiate the efficacy and safety of its novel therapies.
Intellectual Property and Market Position
Central to Atossa’s strategy is its strong intellectual property portfolio, which includes multiple issued U.S. patents and numerous pending applications. These patents cover both the composition of matter for (Z)-endoxifen and innovative formulation approaches, ensuring a competitive edge in the market. By protecting its technology and research investments, the company lays a solid foundation for long-term value creation, even as it navigates the challenges inherent to clinical stage development.

Atossa Therapeutics (NASDAQ: ATOS) presented research on the anti-cancer activity of (Z)-endoxifen and its byproducts at the AACR Special Conference. The study investigated four (Z)-endoxifen byproducts for treating estrogen receptor-positive (ERα+) breast cancer, including endocrine-resistant tumors.
Two compounds, AT416E and AT402E, showed strong anti-proliferative activity, with AT416E demonstrating enhanced inhibition of cell migration and invasion. All four byproducts exhibited greater anti-proliferative effects than (Z)-endoxifen in estrogen-deficient conditions, while (Z)-endoxifen proved most effective at inducing cell cycle arrest and apoptosis.
The company plans future in vivo studies to validate these compounds' potential in overcoming current endocrine therapy limitations.
