Studying Complement Inhibition in Patients With Moderate to Severe Hidradenitis Suppurativa

Phase 2

Completed

• Conditions: Hidradenitis Suppurativa
• Interventions: Biological: IFX-1

• Registration Number: NCT03001622
• Lead Sponsor: InflaRx GmbH

Brief Summary

The trial enrolls patients with moderate to severe Hidradenitis Suppurativa (HS). The primary goal of the trial is to evaluate the safety and tolerability of IFX-1 administered over 8 weeks in these patients. In addition the trial aims to characterize the pharmacokinetics and pharmacodynamics of IFX-1 as well as to generate preliminary data on the efficacy of IFX-1 on clinical endpoints (e.g., Hidradenitis Suppurativa Clinical Response (HiSCR), Dermatology Life Quality Index (DLQI), Visual Analog Scale (VAS) for disease, VAS for pain, Hidradenitis Suppurativa - Physician's Global Assessment (HS-PGA), Modified Sartorius Score (mSS)).
