Item 8.01. Other Events.
On October 2, 2023, Praxis Precision Medicines, Inc. (the “Company”) provided an update on its clinical portfolio at the Company's R&D Day. The Company shared the following updates on each of its clinical programs.
Ulixacaltamide
•Additional analysis from the Essential1 data set continues to support the design of the Phase 3 program for ulixacaltamide (“Essential3”).
◦Data from Essential1 showed a meaningful difference in a minimum 3-point improvement in the modified Activities of Daily Living 11-point scale (“mADL11”) between patients on ulixacaltamide versus placebo (55% v. 31%, p=0.023).
◦In the extension period of Essential1, which continued after Week 8 through Week 14, 64% of patients in the ulixacaltamide arm showed at least a 3-point improvement in mADL11 versus baseline. For patients transitioning from placebo at Week 8 onto ulixacaltamide, 69% achieved at least a 3-point improvement to baseline at Week 14.
◦Ulixacaltamide also demonstrated incremental benefit to patients on propranolol. 48% of patients on propranolol and ulixacaltamide in the Essential1 study achieved at least a 3-point improvement in mADL11 compared to 25% for patients on propranolol and placebo.
•mADL11 confirmed to serve as primary endpoint in both Phase 3 studies of Essential3 based on protocol feedback received from the U.S. Food and Drug Administration (the “FDA”).
•The Company expects to submit a New Drug Application for ulixacaltamide in 2025.
PRAX-222
•Dosing for Part 1 of the EMBRAVE study is nearing completion, with patients receiving 1 mg doses once a month for four months at LeBonheur Children’s Hospital in Memphis, Tennessee.
•No treatment related adverse events (“AEs”) or serious adverse events (“SAEs”) were observed in preliminary safety analysis as of the cutoff date of September 26, 2023.
•As of the cutoff date, data was evaluable for three of four dosing periods showing:
◦Patients achieved a 44% median reduction in seizures versus baseline, on top of best available standard of care.
◦Patients observed an increased number of days without seizures, achieving a median of 35% seizure free days over the dosing period compared to a baseline of 21% seizure free days.
◦All patients achieved significant seizure reduction after one dose.
•The Company intends to request a meeting in the fourth quarter of 2023 with the FDA to align on next steps for the program.
PRAX-628
•Additional data from the Phase 1 single ascending dose (“SAD”) and multiple ascending dose (“MAD”) study continue to reinforce the potential of PRAX-628 as a next generation precision anti-seizure medication (“ASM”).
•Electroencephalogram (“EEG”) data showed rapid and sustained activity in the brain when dosing PRAX-628 as compared to placebo.
•PRAX-628 achieved and sustained target therapeutic concentrations in excess of the equivalent Maximal Electroshock Seizure Model (“MES”) EC50 after first administration.
•The Company expects to read out the results from the Phase 2 Photoparoxysmal Response (“PPR”) study in the fourth quarter of 2023.
PRAX-562
•The Company is utilizing a decentralized recruiting and enrollment approach for its Phase 2 EMBOLD study for the treatment of pediatric patients with developmental and epileptic encephalopathies, with sites in both the United States and Europe.
•The Company expects topline results from the EMBOLD study in the first half of 2024.
