Jason McCarthy’s rating is based on the promising potential of Atossa Therapeutics’ oral endoxifen, particularly in the treatment of metastatic breast cancer (mBC). The recent FDA approval of Eli Lilly’s imlunestrant highlights the demand for new therapeutic options in this space, and Atossa’s endoxifen shows favorable comparisons in terms of progression-free survival (PFS). In prior studies, endoxifen demonstrated a PFS of 7.2 months, which is promising compared to other treatments.
Moreover, endoxifen offers a distinct advantage as it is mutation-agnostic and does not require metabolic activation, unlike tamoxifen. This characteristic ensures consistent plasma exposure and potentially restores receptor blockade in resistant tumors. Atossa’s ongoing research, including molecular modeling and in vitro work, further supports endoxifen’s potential efficacy in stabilizing the inactive form of the estrogen receptor, making it a compelling candidate for future clinical trials and regulatory filings.
