A Study to Evaluate the Safety, Tolerability, Pharmacokinetics (PK), Proof of Mechanism of GSK2618960 in Primary Sjögren's Syndrome (pSS)

6 de marzo de 2018 actualizado por: GlaxoSmithKline

A Two Part Phase IIa Study, to Evaluate the Safety and Tolerability, Pharmacokinetics, Proof of Mechanism and Potential for Efficacy of an Anti-IL-7 Receptor-α Monoclonal Antibody (GSK2618960) in the Treatment of Primary Sjögren's Syndrome

This study aims to evaluate the safety, tolerability and PK of repeat dose administration of GSK2618960 in the treatment of pSS. The study will contain two parts, Part I will be open label and Part II will be randomized, double-blind. The minimum duration of Part I & Part II of the study will be 26 and 32 weeks respectively.
