Atossa Therapeutics, Inc. (NASDAQ: ATOS) is a pioneering biopharmaceutical company headquartered in Seattle, Washington. Established in 2009, Atossa focuses on developing innovative and proprietary medicines targeting unmet medical needs in oncology, with a particular emphasis on breast cancer. The company is currently in the clinical stage, advancing several key programs designed to improve cancer treatment and prevention.
Atossa's core program is the development of (Z)-endoxifen, a potent metabolite of tamoxifen, crucial for treating and preventing breast cancer. Currently, (Z)-endoxifen is in Phase II clinical trials aimed at various breast cancer conditions, including estrogen receptor-positive breast cancer, ductal carcinoma in situ (DCIS), and mammographic breast density. The company is also exploring its efficacy in combination therapies with drugs like abemaciclib, a CDK 4/6 inhibitor.
In addition to breast cancer, Atossa has ventured into COVID-19 therapeutics with two potential treatments: AT-H201 for improving lung function in severe COVID-19 patients and AT-301, a nasal spray for at-home use.
Recently, Atossa has achieved several milestones, including the successful dosing of the first patient in the RECAST DCIS study, full enrollment of its Phase II Karisma-Endoxifen trial, and promising preliminary data from the 40mg cohort in the EVANGELINE study. The company also regained compliance with Nasdaq's minimum bid price requirement.
Atossa's collaborative efforts include partnerships with Quantum Leap Healthcare Collaborative and Weill Cornell Medicine, advancing studies in combination therapies and breast cancer risk assessment through innovative AI models. With a strong financial position, including $84 million in cash and no debt as of Q1 2024, Atossa is well-positioned to continue its groundbreaking work in oncology.
Atossa Therapeutics (Nasdaq: ATOS) CEO Dr. Steven Quay addressed the significant decline in mammograms during the global pandemic in a recent video for Breast Cancer Awareness Month. He emphasized that many women have not been seeking mammograms since COVID-19 began, which is particularly concerning for women of color and those in lower income brackets, as highlighted in a peer-reviewed article. Atossa continues to focus on innovative treatments for oncology and COVID-19, aiming to address these urgent medical needs.
Atossa Therapeutics has begun enrolling participants in a clinical study for its nebulized formulation, AT-H201, aimed at improving lung function in both moderately to severely ill hospitalized COVID-19 patients and those suffering from post-infection pulmonary issues. The study will include 60 participants and is being conducted in Australia. AT-H201 combines two FDA-approved drugs and has shown to be significantly more potent than existing treatments like Remdesivir. Successful completion of this study and obtaining regulatory approval is crucial for commercialization.
Atossa Therapeutics (Nasdaq: ATOS) adjourns a special stockholder meeting to October 7, 2021, to allow more time for voting on a proposal to increase authorized shares.

The new shares aim to fund acquisitions and collaborations, with no intention to raise capital below $10 per share in the nine months following approval. Stockholders can vote via phone at (833) 786-6488.
Atossa Therapeutics (Nasdaq: ATOS) has received approval from the Swedish Ethics Review Authority to initiate a Phase 2 clinical trial of oral Endoxifen aimed at reducing mammographic breast density (MBD). MBD affects over 10 million women in the U.S. and can complicate cancer detection. The trial, named Karisma-Endoxifen, will enroll around 240 healthy premenopausal women for a six-month study period. The primary goal is to evaluate the dose-response relationship of daily Endoxifen on MBD, with secondary objectives assessing safety and tolerability.
Atossa Therapeutics, Inc. (Nasdaq: ATOS) reported financial results for Q2 2021, ending June 30, with cash balances of $142.4 million. The company achieved significant outcomes in its Phase 2 clinical studies, notably a 65.1% reduction in Ki-67 levels in breast cancer patients. Regulatory approvals from Sweden and Australia allow for the initiation of further clinical studies of Endoxifen and AT-H201. However, operating expenses surged by 78% and R&D costs rose by 130% compared to the previous year, reflecting increased clinical trial activities.

On July 26, 2021, Steven Quay and international scientists released a pre-print paper examining the RNA sequencing data of early COVID-19 patients, suggesting severe contamination at the Wuhan Institute of Virology. Findings indicate that specimens from December 2019 contained significant levels of an undisclosed H7N9 influenza vaccine, over six times the amount of SARS-CoV-2. Additionally, Nipah virus gene sequences were identified, raising concerns about genetic manipulation. This contamination is problematic, given the lethal nature of the pathogens involved.
An international team of scientists, led by Dr. Steven Quay, has published a paper suggesting that a laboratory-acquired infection could be a more likely origin of COVID-19 than natural zoonotic transmission. The paper, presented to the US Congress, highlights insufficient biosafety levels in Wuhan labs and the absence of animal-to-human transmission evidence. Dr. Quay advocates for treating the lab leak theory as the primary hypothesis until new evidence emerges. Quay, a prominent figure in medicine, has contributed significantly to pharmaceuticals and pandemic survival strategies.
Atossa Therapeutics (Nasdaq: ATOS) has received regulatory approval from the HREC to initiate a clinical study of its nebulized formulation AT-H201 in Australia.

The Phase 1/2a study will evaluate 60 participants and aims to determine the efficacy of AT-H201, which has shown promising potency in in vitro tests against SARS-CoV-2. Successful trial results and regulatory approvals are essential for commercialization.
