SER-252 Registrational Study Design Overview
The SER-252-1b study is a randomized, double-blind, placebo-controlled Phase 1b trial with single-ascending-dose (five cohorts of eight; n=40) and multiple-ascending-dose components (up to three cohorts of sixteen; n=48) in adults with Parkinson’s disease and motor fluctuations. The registrational study is designed to evaluate safety, tolerability, and pharmacokinetics of subcutaneous SER-252 versus placebo, with exploratory efficacy measures that include MDS-UPDRS motor scores and structured motor-state assessments. Dose escalation will be overseen by a Safety Review Committee and the study will be conducted across sites in the U.S. and Australia.
About SER-252 (POZ-apomorphine)
SER 252 is an investigational apomorphine therapy developed with Serina’s POZ platform and designed to provide continuous dopaminergic stimulation (CDS) via a single or twice-weekly subcutaneous injection. CDS has been shown to reduce the severity of motor fluctuations (which includes levodopa-induced dyskinesia) and enable greater daily on time, with reduced off time, in advanced Parkinson’s patients. SER-252 leverages strategic partner Enable Injections’ enFuse™ wearable drug delivery platform to enhance patient comfort and convenience, providing CDS to patients via an easy-to-administer, long-acting subcutaneous injection.
