Serina Therapeutics Says SER-252 Cohort 1 Advances Study to Cohort 2 Dose Escalation

Neutral Impact 3 of 5 other Written later

Serina Therapeutics reported that an independent Safety Monitoring Committee completed a blinded review of Cohort 1 in its Phase 1b study of SER-252 in advanced Parkinson's disease and recommended advancing to Cohort 2. Blinded Cohort 1 data at the lowest dose showed a pharmacokinetic profile consistent with sustained apomorphine exposure and sustained motor improvement in some individual patients on exploratory measures. The company expects topline data from the single-ascending-dose portion in the first half of 2027, but the Cohort 1 data are preliminary, blinded, exploratory and based on a small number of patients.

Key points

  • Cohort 1 enrolled eight patients, randomized 3:1 to SER-252 or placebo, and evaluated the lowest dose level.
  • The Independent Safety Monitoring Committee recommended advancing to Cohort 2 based on blinded safety and tolerability data.
  • Serina expects to report topline data from the single-ascending-dose portion of the study in the first half of 2027.
  • The filing states Cohort 1 data are preliminary, blinded, and exploratory and may not be evidence of treatment effect.
