Praxis Precision Medicines and Remagine Labs Announce Strategic Collaboration to Develop Transdermal Ulixacaltamide for Essential Tremor

Collaboration aims to quickly enable ulixacaltamide to be delivered via active transdermal route

        Potential to expand the addressable market for ulixacaltamide beyond the initial patient population and to enable additional life-cycle management opportunities

        Praxis to make equity investment in Remagine Labs, accelerating the companies' collaboration

BOSTON, Mass. and AUSTIN, Texas, July 07, 2026 (GLOBE NEWSWIRE) -- Praxis Precision Medicines, Inc. (NASDAQ: PRAX), a fully integrated central nervous system (CNS) precision neuroscience biopharmaceutical company, and Remagine Labs, Inc., a developer of electronically controlled transdermal drug delivery systems, today announced a research collaboration and license agreement to develop an iontophoretic transdermal patch for the delivery of ulixacaltamide, Praxis's highly selective T-type calcium channel inhibitor in development for essential tremor (ET).

Ulixacaltamide is Praxis's lead asset in ET and the most clinically advanced therapy in the field. The FDA accepted the ulixacaltamide New Drug Application (NDA) for ET in April 2026 and has set a Prescription Drug User Fee Act (PDUFA) target action date of January 29, 2027. Ulixacaltamide received Breakthrough Therapy Designation in December 2025 on the strength of the Essential3 Phase 3 program.

ET affects approximately seven million people in the United States, with very limited therapeutic options and no drug specifically developed for ET, representing a large, underserved, multi-billion-dollar opportunity.

Under the agreement, Praxis and Remagine will collaborate to apply Remagine's proprietary platform, designed for precise, multi-day active transdermal dosing, to ulixacaltamide, complementing Praxis's lead oral program. A transdermal option is intended to broaden the population ulixacaltamide can reach, while strengthening ulixacaltamide's competitive positioning and extending the long-term value of the franchise. Praxis has also made an equity investment in Remagine Labs, underscoring the companies' shared commitment to quickly advancing the program.

“Ulixacaltamide is poised to be the first new therapy for essential tremor in decades, and we are already building for its future,” said Marcio Souza, president and chief executive officer of Praxis Precision Medicines. “With our NDA under FDA review and a PDUFA target action date of January 29, 2027, this collaboration lets us advance a differentiated delivery option that could expand the population we reach and extend the value of the franchise. Pairing a validated mechanism with programmable transdermal delivery reflects our commitment to leading in essential tremor, for ulixacaltamide and, potentially, for other programs in our portfolio.”

“We are excited to collaborate with Praxis, a company with deep expertise in developing innovative therapies for central nervous system disorders,” said Pat Kelly, Co-founder and CEO of Remagine Labs. “Together, we have the opportunity to explore how our electronically controlled transdermal delivery platform can expand the possibilities fr CNS therapeutics. This collaboration represents an important milestone for Remagine and further validates the potential of our technology to enable differentiated drug-device combination products.”
