What was shared by MIST?
In patients with paroxysmal supraventricular tachycardia, Milestone Pharmaceuticals (MIST) today reported encouraging topline effectiveness and safety data from the Phase 3 RAPID clinical trial of etripamil, the Company’s experimental calcium channel blocker (PSVT).
- 706 individuals were included in the RAPID study, which was multi-center, randomized, double-blind, and placebo-controlled.
- Without any kind of medical supervision, patients were randomized 1:1 to receive either an etripamil nasal spray or a placebo.
- Patients who did not experience symptom alleviation after 10 minutes were instructed to self-administer a repeat dosage of the study medicine in order to optimize the potential therapeutic impact of etripamil.
- Patients using etripamil showed a very statistically significant and clinically significant improvement in time to PSVT conversion compared to placebo, achieving the primary goal of the RAPID study.
- When etripamil was used instead of a placebo, a statistically substantially higher percentage of patients converted after 30 minutes, according to a Kaplan Meier analysis.
- PSVT is a sporadic, disruptive burden on patients, and the only available therapies are expensive, uncomfortable acute care settings.
- The RAPID trial’s results showed that etripamil-treated patients converted to normal sinus rhythm considerably more frequently than placebo-treated patients, without incurring major adverse effects and without the need for medical care.
- These findings suggest the possibility that etripamil will provide patients with a clinically significant benefit and serve as a crucial and beneficial tool for their doctors.
- Overall, mild (68%) to moderate (31%%) RTEAEs were noted for the majority of patients.
- No major adverse events (AEs) connected to etripamil were recorded.
- More than 1,600 different patients have now received etripamil dosages of less than 70 mg as a consequence of the Company’s entire PSVT clinical study.
What conclusions has MIST drawn from the data?
In the Etripamil clinical trial, Milestone Pharmaceuticals (MIST) observed a statistically significant decrease in the use of extra medical treatments as well as a statistically significant decrease in visits to the emergency room, according to analyses of pooled data from the NODE-301 and RAPID trials. MIST’s complete findings of Phase 3 RAPID clinical trial are anticipated to be presented at a subsequent medical symposium and submitted for publication in a peer-reviewed journal.
