Otsuka and Teva Sign Licensing Agreement for Japan for Fremanezumab

Otsuka Pharmaceutical Co., Ltd and Teva Pharmaceutical Industries, Ltd.  announce an agreement covering Japan for Otsuka to develop and commercialize Teva’s investigational drug candidate fremanezumab (TEV-48125), an anti-calcitonin gene-related peptide (CGRP) monoclonal antibody for the prevention of migraine.

Fremanezumab is administered monthly as a subcutaneous injection. Through the agreement, Otsuka secures exclusive rights in Japan to fremanezumab, which Teva is globally developing in other countries.

The annual prevalence of migraine in Japan is 8.4% of adults and approximately 8.4 million patients suffer from the condition. The highest prevalence rate is among young women, with approximately 20% of cases reported among women in their 30s.1 Acute as well as preventive treatments exist for migraine, but there is an unmet need for targeted, preventive treatments.

In global Phase IIb studies conducted by Teva for episodic and chronic migraine, all doses achieved their primary and secondary study endpoints. The data indicated a significant reduction in both the number of monthly cumulative headache hours (primary endpoint in chronic migraine), and the number of migraine days (primary endpoint in episodic migraine), relative to baseline. No treatment-related serious adverse events were reported with the use of fremanezumab. Common adverse events observed in clinical trials included mild injection-site pain or erythema and pruritus.

About the Agreement

With the agreement consummated, Otsuka is to pay Teva a lump-sum payment of $50 million. Milestone payments will be made upon filing and regulatory approval in Japan and then upon achievement of specified revenue targets. Future clinical trials in Japan will be carried out and funded by Otsuka. In addition, Otsuka holds exclusive sales rights and will pay royalties on revenues to Teva.

About Fremanezumab (TEV-48125)

Fremanezumab is a monthly subcutaneous injection that is under development for the prevention of migraine, with clinical trials conducted in chronic and episodic migraine as well as chronic and episodic cluster headache. It is thought to prevent migraine by selectively binding to CGRP ligand, a well-validated target in migraine. The effectiveness and safety of four dose levels of fremanezumab were previously studied in phase IIb, placebo-controlled, double-blind trials (about 300 participants) for the prevention of recurrent, episodic migraine and chronic migraine.
