Quince Therapeutics Inc. has announced the publication of a new population pharmacokinetic $(PK)$ modeling study of its Phase 3 lead asset, eDSP (dexamethasone sodium phosphate encapsulated in a patient's own red blood cells), in the journal CPT: Pharmacometrics & Systems Pharmacology. The study focused on pediatric patients with Ataxia-Telangiectasia (A-T) and healthy adults, evaluating monthly administration of eDSP and predicting drug exposure in the A-T patient population over a six-month period. Results from the study indicate that eDSP maintains low, sustained plasma concentrations of DSP for 20 to 30 days without drug accumulation. Previous clinical trials, including the Phase 3 ATTeST trial and Open Label Extension study, reported a favorable safety profile for eDSP, with minimized corticosteroid-related side effects and no evidence of drug accumulation after repeated dosing. The results of this PK modeling study have already been published.
