Almirall signs license agreement with Sun Pharma for Tildrakizumab in Europe for psoriasis

First IL-23p19 antibody to meet primary endpoints in pivotal phase-3 clinical trials in patients with moderate-to-severe plaque psoriasis

Sun Pharma and its wholly owned subsidiary and Almirall have announced a licensing agreement on the development and commercialisation of tildrakizumab for psoriasis in Europe. Tildrakizumab is an investigational IL-23p19 inhibitor currently being evaluated in patients with moderate-to-severe plaque psoriasis.

Under terms of the license agreement, Almirall will pay Sun Pharma an initial upfront payment of $50 million. Phase-3 studies of tildrakizumab have recently been completed. Sun Pharma will be eligible to receive development and regulatory milestone payments and, additionally, sales milestone payments and royalties on net sales, the terms of which are confidential. Almirall will be able to lead European studies, and participate in larger global clinical studies for psoriasis indication subject to the terms of the Sun Pharma – Merck agreements, as well as certain cost sharing agreements. Sun Pharma will continue to lead development of tildrakizumab for other indications, where Almirall will have right of first negotiation for certain indications in Europe.

“Sun Pharma is committed to growing our dermatology franchise, with tildrakizumab as our lead investigational compound. We continue to build our pipeline and capabilities in this important therapeutic area of significant unmet need. We are proud to be partnering with a regional leader in dermatology, like Almirall, to bring tildrakizumab to the European market,” said Dilip Shanghvi, Managing Director, Sun Pharma.

“This agreement with Almirall follows the recent announcement that tildrakizumab is the first IL-23p19 inhibitor to demonstrate positive results in Phase-3 clinical trials and is another step towards preparing for future regulatory milestones that will potentially enable us to bring a new treatment option to patients with moderate-to-severe plaque psoriasis,” he added.

“This agreement with Sun Pharma allows us to add a novel biologic for treatment of psoriasis to our extensive dermatology portfolio,” said Jorge Gallardo, President of Almirall. “This is an exciting time for the treatment of psoriasis, a disease which can take both a physical and emotional toll on patients’ lives. Emerging new investigational drugs, like tildrakizumab, are increasingly targeted and will potentially offer patients and physicians another alternative,” he added.

Additionally, the license agreement has a provision for possible co-promotion agreement at some point in the future, subject to certain conditions.

In May 2016, the two pivotal Phase-3 clinical trials of tildrakizumab met their primary endpoints for both evaluated doses. The co-primary efficacy endpoints were: the proportion of participants with psoriasis Area Sensitivity Index 75 (PASI 75) response at week 12 compared to placebo and the proportion of participants with a Physician’s Global Assessment (PGA) score of clear or minimal with at least a 2-grade reduction from baseline at week 12 compared to placebo. The overall safety profile of tildrakizumab in both Phase-3 clinical trials was consistent with the safety data observed in previously reported studies. Additionally, the second study included an etanercept comparator arm, with a key secondary endpoint comparing tildrakizumab and etanercept on PASI 75 and PGA. Tildrakizumab 200 mg was superior to etanercept on both PASI 75 and PGA endpoints at week 12, while the 100 mg dose showed superiority to etanercept on PASI 75 only.

The preparations for submission of a Biologics License Application to the US Food and Drug Administration are proceeding. The detailed findings from the Phase-3 clinical trials will be presented at upcoming scientific meetings.
