A Trial to Compare BI drug with Placebo for Patients With Scleroderma

Phase 2

Active, not recruiting

• Conditions: Systemic sclerosis, unspecified,

• Registration Number: CTRI/2023/07/054769
• Lead Sponsor: Boehringer Ingelheim

Brief Summary

This is a multi-centre,multi-national, prospective, randomised, placebo-controlled, double-blind, parallel-group, PhaseII clinical trial to investigate the efficacy and safety of oral BI 685509 at atarget dose of 3 mg TID, in adult patients with early progressive dcSSc andvasculopathy.

 Patients will be enrolled in thetrial and screened for eligibility once they have signed the informed consent.The screening period has a maximum of 5 weeks. Eligible patients will proceedto the 48-week treatment period. BI 685509 versus placebo use will beestablished in a 1:1 randomisation after the screening period.

 The treatment period includes a4-week up-titration of BI 685509 from 1 mg to 3 mg TID: BI 685509 1 mg will begiven TID for 2 weeks. If tolerated, BI 685509 2 mg TID will be given for 2weeks and then escalated to 3 mg TID. If the patient develops symptomatic orthostatichypotension on 2 mg TID, they will have to stop trial medication and contactthe site for dose adjustment. The same procedure will be followed afterescalation from 2 mg to 3mg. Every dose adjustment will require a patient visitat the site. It is anticipated that approximately 10% of patients may not beable to fully titrate up to the 3 mg TID dose.

The main efficacyanalysis will be assessed at Week 48. After completing the first 48 weeks oftreatment, patients may continue to receive their assigned trial treatment inthe extended treatment period, until the last patient has completed thetreatment period. Patients will then enter a 4-week follow-up period that doesnot include trial treatment, for ongoing safety and efficacy data collection.The patient’s trial participation is complete when they have completed the lastplanned visit (i.e., EOS, 4 weeks after EOT).

• Such methods should be used throughout the trial.
• A list of contraceptive methods meeting these criteria is provided in the CTP.

Exclusion Criteria

• Any known form of pulmonary hypertension.
• Limited cutaneous SSc at screening.

Study & Design

• Study Type: Interventional
• Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
The primary objective is to demonstrate superiority of BI 685509 at a target dose of 3 mg TID over placebo based on the mean difference in annual rate of decline in FVC over 48 weeks. The treatment effect of primary interest will be based on all randomised patients including the effects of any changes of treatment, i.e., a treatment policy strategy will be used.	48 weeks

Secondary Outcome Measures

Name	Time	Method
Secondary objectives are to demonstrate superiority of BI 685509 over placebo for absolute change from baseline in mRSS, FVC (% predicted), patient and physician global assessment, HAQ-DI, RP activity and DU net burden at Week 48, the ACR-CRISS, revised CRISS and for time to treatment failure. Additional objectives are to evaluate safety, PK, and exploratory biomarkers.	48 weeks
