In a positive development for the company, Atossa has received constructive written feedback from the U.S. Food and Drug Administration (FDA) regarding a proposed dose optimization trial for (Z)-endoxifen, an innovative treatment targeting estrogen receptor positive (ER+), human epidermal growth factor receptor 2 negative (HER2-) metastatic breast cancer. The FDA’s response affirms critical elements of Atossa’s clinical development plan, allowing the company to proceed without a scheduled virtual meeting and paving the way for a planned Investigational New Drug (IND) submission by the fourth quarter of 2025.

Dr. Steven Quay, Chief Executive Officer and Chairman of the Board, noted that this feedback marks a pivotal milestone for Atossa, reinforcing confidence in their clinical strategy. The FDA’s endorsement encompasses the proposed dosing optimization approach, supports the rationale for the combination of (Z)-endoxifen with established therapies, and confirms adequate nonclinical safety data to advance without additional toxicity studies. Furthermore, the cardiac safety assessment plan for the monotherapy phase of the trial has received approval.

Atossa is now poised to expedite the clinical development of (Z)-endoxifen, focused on enhancing treatment options for patients facing metastatic breast cancer. The company plans to release detailed information regarding the trial design and targeted patient populations in the near future, continuing its commitment to scientific innovation and improving patient outcomes in the breast cancer treatment landscape.
