AstraZeneca has entered into a collaboration agreement with Valeant Pharmaceuticals International, Inc. under which it will grant an exclusive license for Valeant to develop and commercialise brodalumab.
Brodalumab is an IL-17 receptor monoclonal antibody in development for patients with moderate-to-severe plaque psoriasis and psoriatic arthritis. Under the agreement, Valeant will hold the exclusive rights to develop and commercialise brodalumab globally, except in Japan and certain other Asian countries where rights are held by Kyowa Hakko Kirin Co., Ltd under a prior arrangement with Amgen Inc., the originator of brodalumab. Valeant will assume all development costs associated with the regulatory approval for brodalumab. Regulatory submission in US and EU for brodalumab in moderate-to-severe psoriasis is planned for the fourth quarter of 2015.
Under the terms of the agreement, Valeant will make an up-front payment to AstraZeneca of $100 million as well as additional pre-launch milestones of up to $170 million and further sales related milestone payments of up to $175 million following launch. After approval, AstraZeneca and Valeant will share profits.
Brodalumab is supported by data from the three AMAGINE Phase III pivotal studies. The results highlighted that brodalumab has an effective mechanism of action that delivers clinical benefit and could help a significant number of moderate-to-severe plaque psoriasis patients achieve total clearance of their skin disease. At the 210 mg dose, brodalumab was shown to be efficacious in total skin clearance of psoriasis compared to placebo and superior to ustekinumab at week 12 in two replicate comparator trials involving over 3,500 patients.
