Safety, Efficacy and PK/PD of QGE031 vs. Placebo in Patients With Active Bullous Pemphigoid Despite Oral Steroid Treatment

Phase 2
Terminated
Conditions
Bullous Pemphigoid
Interventions
Drug: Placebo
Registration Number
NCT01688882
Lead Sponsor
Novartis Pharmaceuticals
Brief Summary

To evaluate the safety and efficacy of QGE031 versus placebo in patients with bullous pemphigoid. Efficacy will be assessed as a reduction of disease activity. How QGE031 is broken down by the body and the impact it has on different blood and tissue markers will also be explored.

Detailed Description

This study was planned to be divided into 2 distinct parts. Part 1 was a multicenter, randomized, placebo-controlled study evaluating the efficacy, safety, PK and PD of multiple, subcutaneous doses of QGE031 in the treatment of patients with BP with disease refractory to oral steroid treatment. Patients were treated with QGE031 or placebo in a 2:1 ratio.

Part 2 of this study was planned to be a multi-center, open label, dose range finding study evaluating the efficacy, safety, PK and PD of multiple, subcutaneous doses of QGE031 in the treatment of patients with BP with disease refractory to oral steroid treatment.

This study was stopped after Part 1 completed and was terminated because the predefined criteria of efficacy was not reached ( \>50% better then placebo)

Primary Outcome Measures
NameTimeMethod
Number of Patients That Had a Clinical Global Assessment of Change (CGA-C) Responder Rate by Week 1212 weeks

Clinical Global Assessment of Change (CGA-C) responder rate was the responder rate at 12 weeks based on the CGA-C in bullous pemphigoid (BP).

A patient with a CGA-C score of 3 or 4 indicating 'at least marked improvement from baseline' at 12 weeks was considered a responder. The CGA-C is an investigator assessment of change from baseline and is scored as follows: -4 = Very marked worsening (100% worsening); -3 = Marked worsening (67-99% worsening); -2 = Moderate worsening (34-66% worsening); -1 = Slight worsening (1-33% worsening); 1= Slight improvement (1-33% improvement); 2 = Moderate improvement (34-66% improvement); 3 = Marked improvement (67-99% improvement); 4 = Complete clearance (100% improvement)

Investigator's Global Assessment (IGA) - (scale of 0 to 4, where 0=clear, 1=almost clear, 2=mild, 3=moderate and 4=severe)

Response Based on Clinical Global Assessment of Change CGA-C Score at 6 Weeks6 weeks

Clinical Global Assessment of Change (CGA-C) responder rate was the responder rate at 6 weeks based on the CGA-C score in bullous pemphigoid (BP).

A patient with a CGA-C score of 3 or 4 indicating marked improvement from baseline at 6 weeks was considered a responder. The CGA-C is an investigator assessment of change from baseline and is scored as follows: -4 = Very marked worsening (100% worsening); -3 = Marked worsening (67-99% worsening); -2 = Moderate worsening (34-66% worsening); -1 = Slight worsening (1-33% worsening); 1= Slight improvement (1-33% improvement); 2 = Moderate improvement (34-66% improvement); 3 = Marked improvement (67-99% improvement); 4 = Complete clearance (100% improvement)
