BUFFALO, N.Y., Oct. 28, 2019 (GLOBE NEWSWIRE) -- Athenex, Inc. (ATNX), a global biopharmaceutical company dedicated to the discovery, development and commercialization of novel therapies for the treatment of cancer and related conditions, today announced a progress update from partner Almirall on tirbanibulin ointment (also known as ALM14789, formerly known as KX-01 or KX2-391) for the treatment of actinic keratosis (AK).
|ALM14789 for actinic keratosis |
As announced in the 2019 American Academy of Dermatology Annual Meeting in Washington, DC (on March 2, 2019), both Phase III studies, KX01-AK-003 and KX01-AK-004, achieved their primary endpoint, which was defined as 100% clearance of the AK lesions at Day 57 within the face or scalp treatment areas: Complete Clearance was observed in 44% and 54% of the patients for tirbanibulin respectively while it was 5% and 13% for vehicle treated groups.
Only patients showing complete clearance at the primary evaluation endpoint on day 57 were followed quarterly in the extension period until recurrence was observed in the treatment area. Recurrence rates were defined as proportion of patients in whom at least one treated or new actinic keratosis lesion was identified in the treated area throughout one year follow up.
The recurrence rates in patients treated with tirbanibulin 1% ointment were 74% and 72% in the pivotal trials KX01-AK-003 and KX01-AK-004, respectively. Overall, at the recurrence follow up study visit when actinic keratosis (maximum eight initial number of lesions) in the treated area was first observed, 86% had only one or two lesions and 48% reported at least one lesion that was not identified at the time of the initial treatment i.e. newly occurring lesions that were considered as recurrences.
These results represent the last piece of information to submit the New Drug Application (NDA) in the US and the Marketing Authorization Application (MAA) in Europe that are expected to be launched in Q1 2021 and Q2 2021 respectively.
Dr. Rudolf Kwan, Chief Medical Officer of Athenex, stated, “We are pleased with the continued progress of the tirbanibulin ointment program. We recently completed pre-NDA consultation with the U.S. FDA and our preparations for the NDA submission in the U.S. are on track. We look forward to working with our partner, Almirall, towards commercializing this product, if approved.”
In December 2017, Athenex granted Almirall, S.A., a leading skin-health focused global pharmaceutical company, an exclusive license to research, develop and commercialize tirbanibulin in the U.S. and European countries, including Russia. Athenex is responsible for the U.S. FDA regulatory for tirbanibulin ointment in AK. Almirall will employ its expertise to support the development in Europe and also to commercialize the product in the defined territories.
