“We were extremely happy to see the OLE and randomized withdrawal results providing further support of the potential durable benefit and safety profile of ulixacaltamide,” said Marcio Souza, president and chief executive officer of Praxis. We believe the randomized withdrawal sub-study confirmed the robustness of the Phase 3 design and, together with the 14-week data from the OLE of Essential1, reinforce the assumptions used for our upcoming Phase 3 program. We look forward to sharing more about these data and our Phase 3 program details at our upcoming R&D portfolio day in early October.”
Open-Label Extension
Following completion of the initial 8-week double-blind treatment phase in Essential1, eligible patients had the option to continue their access to ulixacaltamide in an open-label extension (OLE) phase. Participants who continued to the OLE phase remained blinded for a 6-week lead-in period.
Randomized Withdrawal Sub-Study
Following the announcement of the Essential1 study topline results, Praxis amended the open-label protocol to further assess the criteria to be used in the upcoming randomized withdrawal Phase 3 study. In this sub-study, patients were re-randomized in a blinded fashion to either receive placebo or continue to receive ulixacaltamide. Twenty-one patients who completed assessments at week 14 of the OLE were eligible to participate in the blinded sub-study. Patients were evaluated weekly over a total of 6 weeks, with 11 patients assigned to ulixacaltamide and 10 to placebo for the initial 3-week period, crossing over to either placebo or ulixacaltamide for an additional 3-week period. Blinded rescue was triggered for patients on placebo if loss in the mADL11 exceeded 2 points at any timepoint.
The results from the sub-study supported a number of proposed design elements for the upcoming Phase 3 randomized withdrawal study, including the responder criteria and feasibility of rescuing patients with ulixacaltamide. Additional study design elements will be discussed in more detail at an upcoming R&D portfolio event in early October.
About Essential Tremor Essential Tremor (ET) is the most common movement disorder, affecting roughly seven million people in the United States alone, including approximately two million diagnosed patients. ET is characterized by involuntary rhythmic movement in the upper limbs, with or without tremor in other body locations such as the head, vocal cords, or legs. These tremors significantly disrupt daily living and are progressive in nature, with increases in tremor severity and amplitude commonly observed over the course of the disease. There is only one approved pharmacotherapy for ET, propranolol, a beta blocker approved by the FDA in 1967, that offers limited efficacy and poor tolerability and that is contraindicated for comorbidities that affect a significant share of the ET population. Other beta blockers and anti-convulsants are used off-label, though similarly are characterized by limited efficacy and tolerability. For these reasons, approximately 40% of patients who seek pharmacotherapy treatment for ET discontinue within two years.
