Revance Therapeutics Inc and Mylan NV announce Mylan’s decision to move forward with a development plan, under a 351(k) pathway, for a proposed biosimilar to BOTOX and BOTOX Cosmetic (onabotulinumtoxinA).

Feedback obtained from the US Food and Drug Administration (FDA) during a Biosimilar Initial Advisory Meeting (BIAM) held in February 2019 indicated that the 351(k) regulatory pathway for an onabotulinumtoxinA product is viable. Based on this meeting, along with the results from additional characterization and analysis completed by Revance, the two companies are now moving forward with the development program, according to a media release.

“We are excited to move forward with Revance on a clear and achievable development pathway for what will potentially be the first biosimilar to BOTOX, and to leverage our worldwide reach and commercial expertise to maximize this exciting opportunity globally while expanding access to this important product for patients,” Mylan President Rajiv Malik says in the release. “This collaboration adds another high-profile, large-market, complex biologic, across both aesthetic and therapeutic categories, to our industry-leading biosimilars pipeline.”

Mark Foley, President and Chief Executive Officer of Revance Therapeutics, adds, “We are pleased with Mylan’s decision to opt-in to the biosimilar to BOTOX development program, as it reflects our mutual confidence in the path forward. Assuming regulatory approval, it would allow us to financially participate in the short-acting neuromodulator market, while focusing our commercial efforts on creating the new, long-acting neuromodulator category.”

Mylan and Revance signed a collaboration and license agreement in February 2018 for the development and regulatory approval of a biosimilar to BOTOX, to be followed with commercialization by Mylan in the US, Europe and applicable markets throughout the rest of the world. The agreement included an upfront payment of $25 million to Revance. In August 2019, the companies amended the agreement to include an additional one-time payment of $5 million to extend the period in which Mylan could choose to continue its collaboration and license agreement to develop Revance’s biosimilar to BOTOX.

With Mylan’s decision to move forward with the development program, a payment of $30 million is now payable to Revance by Mylan. Furthermore, the collaboration and license agreement also provides for an additional $70 million in milestone payments, contingent upon the achievement of further clinical and regulatory milestones. Additionally, per the agreement, Revance is eligible to receive sales target milestone payments and royalties in all relevant markets, the release continues.
