Jazz Tremor Drug Misses Primary Endpoint
Jazz Pharmaceuticals says top-line results from its Phase 2b clinical trial (NCT05122650) evaluating the efficacy and safety of suvecaltamide in adult patients with essential tremor did not achieve statistical significance at 30mg versus placebo on the primary endpoint of change from baseline to week 12 on the Essential Tremor Rating Assessment Scale. It says the highly selective and state-dependent modulator of T-type calcium channels was well tolerated and the overall safety profile was consistent with previous studies with no new safety signals observed.
“While not statistically significant, numeric improvements were observed on the primary endpoint and key secondary endpoint at 30mg versus placebo,” Jazz says. “The improvement in placebo from baseline to week 12 also exceeded the company's expectations and was higher than what was observed for placebo in the prior T-CALM trial of suvecaltamide.”
On the safety side, the most common treatment-emergent adverse events were dizziness, headache, paresthesia, diarrhea and insomnia.
