Safety and Tolerability Study of AVID200 in Pts With Diffuse Cutaneous Systemic Sclerosis

NCT ID: NCT03831438

Last Updated: 2024-11-19

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 9 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2019-01-01
• Study Completion Date: 2020-06-20

Brief Summary

Several lines of evidence place TGF-β, a potent pro-fibrotic cytokine, at the centre of the pathogenesis of Systemic Sclerosis (SSC). AVID200 is a novel inhibitor of TGF-β ligands. This Phase 1 trial is designed to evaluate the safety, tolerability and preliminary efficacy of AVID200 in SSc patients in order delineate doses to be further evaluated in Phase 2. Approximately 9 to 24 male and female patients with documented SSc (i.e., score ≥ 9 according to the American College of Rheumatology/European League Against Rheumatism classification criteria), and classified as having the diffuse cutaneous SSs (dcSSc) subset (i.e., according to the LeRoy and Medsger Classification), will be entered into this Phase 1a, multicentre, open-label, dose-escalation, cohort study of AVID200.

Detailed Description

The trial is designed to evaluate the safety and tolerability of sequential escalating doses of AVID200 (study drug), in order delineate a potential effective range of tolerated doses to be further evaluated in Phase 2.

Patients will be treated and followed on an outpatient basis throughout the trial, unless hospitalization is required for other reasons, or to assure patient safety. The choice of doses for further Phase 2 study will be based on clinical and laboratory data obtained during this trial, including safety, PK, and preliminary anti-fibrotic activity.

Upon completion of Cycle 1, and provided re-treatment criteria are met, patients may receive up to 2 additional cycles of study drug unless a criterion for treatment discontinuation has been met.

Conditions

Scleroderma, Diffuse

Study Groups

Dose escalation

Sequential escalating doses of AVID200 when administered once every 2 weeks (Q2W) by 1-hour intravenous (IV) infusion to patient cohorts with diffuse cutaneous systemic sclerosis (dcSSc).

Each 2-week dosing period equals 1 cycle; patients may receive up to 3 cycles of AVID200 (i.e., dosing on D1, 15, and 29 of overall 6 week treatment period).

• Patients with a significant cardiovascular disease or condition, including:

• Congestive heart failure (CHF), Left ventricular ejection fraction (LVEF) known to be below the lower limit of normal (LLN) for the center, or < 50% by multi-gated acquisition (MUGA) scan or echocardiogram (ECHO) if no LLN is defined by the site
