ObsEva's (OBSV) Yselty Gets EU Nod to Treat Uterine Fibroids

Read MoreHide Full Article

ObsEva SA recently announced that the European Commission (EC) has granted marketing authorization to its oral GnRH receptor antagonist, linzagolix, for the management of moderate to severe symptoms of uterine fibroids (UF) in adult women of reproductive age. The drug will be marketed under the trade name Yselty.

The approval follows a positive review by the Committee for Medicinal Products for Human Use (CHMP), which recommended the approval of the oral drug in all member states. The decisions by both EC and CHMP are based on data from two phase III PRIMOSE studies. Pooled week 24 data from both these studies show that treatment with a 200 mg dose of the drug with hormonal ABT achieved a responder rate of 84.5% in participants, while a 100 mg dose without ABT achieved a responder rate of 56.5%.

The EC decision makes Yselty the first and currently the only approved GnRH receptor antagonist that offers women with UF flexible dosing options with and without hormonal add-back therapy (ABT). Yselty is the first oral GnRH antagonist to provide therapeutic alternatives for women who are unable to take hormone therapy.

Shares of ObsEva were up 11% in pre-market trading on Jun 17 following the announcement. In the year so far, the stock has decreased 8% compared with the industry’s decline of 30.4%.

The company has filed a new drug application (NDA) with the FDA, which is currently under review. A final decision on the NDA is expected by Sep 13, 2022.

ObsEva has signed a strategic licensing agreement with London-based Theramex to commercialize Yselty outside of the United States, Canada and Asia. Per the agreement, ObsEva will be eligible to receive royalties of a mid-thirties percentage on commercial sales of the drug. The agreement makes OBSV eligible to receive potential milestone payments.

We remind investors that ObsEva acquired the in-license rights of linzagolix from Japan-based pharma company Kissei in 2015. The rights include global (excluding Asia) commercial rights for the product.
