Sjogrens Syndrome clinical trials

A Randomized, Double-blind 2-arm NEPTUNUS Extension Study to Assess the Long-term Safety and Efficacy of Ianalumab in Patients With Sjogrens Syndrome.

The purpose of this study is to measure the long-term safety and tolerability of ianalumab in participants with Sjogrens syndrome who have previously completed treatment from one of two NEPTUNUS 1 year core studies (CVAY736A2301 or CVAY736A2302). - The study treatment is ianalumab 300 mg in a 2 mL pre-filled syringe for injection. All participants will receive ianalumab either monthly or every 3 months. - The treatment duration will be 3 years with an additional up to 2-year safety follow-up. The total duration of this extension study will be up to 5 years. - The visit frequency will be monthly during both the treatment period and mandatory follow-up, and then less frequently during the subsequent conditional follow-up Treatment of interest: The randomized treatment (ianalumab) will be received monthly or every 3 months. Participants assigned to treatment every 3 months will receive placebo every month between the ianalumab doses to maintain blinding. Number of Participants: Approximately 600 participants from the NEPTUNUS core studies will be rolled over into the extension study. Treatment Groups:There will be no screening period in this trial. From Week 48 of the NEPTUNUS core study, participants will be given the opportunity to consent to this extension study. From Week 52 of the NEPTUNUS core studies (i.e., Day 1 in the extension study), eligible participants will be assigned to either one of the treatment regimens: - ianalumab 300 mg monthly or - ianalumab 300 mg once every 3 months Participants receiving placebo in either of the NEPTUNUS core studies will be randomized 1:1 to receive ianalumab 300 mg monthly or every 3 months starting from Week 60 and participants receiving ianalumab in either of the NEPTUNUS core studies will continue the same treatment in the extension study. Ianalumab will be given as a subcutaneous injection from a 2 mL pre-filled syringe. Participants will be given the opportunity to self-inject at home on some visits after receiving training.
