  • Phase 1 study of topical Endoxifen in men (enrollment and dosing complete; results to be announced this quarter)
  • Phase 2 study of topical Endoxifen to treat gynecomastia in men being treated for prostate cancer (study targeted to open in Q4 2018)
  • Phase 2 study of oral Endoxifen for patients who are “refractory” to Tamoxifen (study targeted to open in 2H 2018)

“Our needs for the ongoing clinical supply of Endoxifen are dramatically increasing as we advance our clinical studies,” commented Dr. Steven Quay, Ph.D., MD, President and CEO of Atossa. “As a second Endoxifen manufacturer, Alchem will begin supplying Endoxifen for one or more of our studies slated for later this year. They will be an excellent partner, with their experience and capabilities, to ensure we are poised to move our development programs forward quickly, particularly in the U.S.,” added Quay.
