AIN457 Regimen Finding Extension Study in Participants With Moderate to Severe Psoriasis

Novartis Pharmaceuticals275 enrolled

Overview

The purpose of this study was to provide long term clinical data for the compound for the treatment of the indication of moderate to severe chronic plaque-type psoriasis.

In the Proof-of-Concept study (CAIN457A2102/ NCT00669916), AIN457 was proven to be efficacious in the treatment of moderate to severe chronic plaque-type psoriasis. As a result, a phase IIb regimen finding study had been started (CAIN457A2211/NCT00941031). The data gathered in this extension study of the core study (CAIN457A2211)was used to expand the safety database of the compound for the treatment of moderate to severe chronic plaque-type psoriasis. The participants in the extension study continued to stay on the exact same treatment regimen they were taking when completing the core study. The extension trial was first designed to provide long-term safety data of up to 100 weeks of treatment (32 weeks in the core study plus 68 weeks in the extension study (part 1)), and an additional 12 weeks of treatment-free follow-up for participants who did not continue in the extension study. Amendment 2 provided an additional 156 weeks of treatment (32 weeks in the core study plus 224 weeks in the extension study, equaling 256 weeks of total treatment (part 2)), before participants entered the 12 weeks of treatment-free follow-up. Protocol Amendment 3 extended the prolongation part of the study by up to 104 additional weeks of treatment (part 3) or until the drug was commercially available in the market of the country of participation, whichever occurred first.

Key Inclusion Criteria: * Patients who completed the core study CAIN457A2211. A patient is defined as having completed the core study if he/she completed the study up to and including visit 13 (F4) of the core study * Patients must be able to understand and communicate with the investigator and comply with the requirement of the study and must given written, signed and dated informed consent before any study assessment is performed. * Patients must be expected to benefit from the ongoing treatment with AIN457, as assessed by the patient and investigator * Male patients must consent to practice reliable contraception during the study and for 16 weeks after the last dose of study drug administration Note: Due to new data available from the toxicology studies, the need for male contraception was removed. Key Exclusion Criteria: * Patients who experience a second consecutive full relapse at visit 13 ( week F4) of the core study CAIN457A2211 * Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until termination of gestation, confirmed by a positive hCG laboratory test (\> 5mlU/mL) * Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unwilling to use effective contraception during the study and for 16 weeks after stopping treatment.

Outcomes

Primary Outcomes

Number of Participants With Adverse Events, Serious Adverse Events and Deaths

Safety was assessed by frequency of adverse events including serious adverse events.

Time frame: up to week 351

Secondary Outcomes

Number of Participants With at Least 50%, 75% or 90% Improvement From Baseline in Psoriasis Area and Severity Index (PASI) and IGA Mod 2009 0 or 1 Response

PASI is a combined assessment of lesion severity and affected area into a single score: 0 (no disease) to 72 (maximal disease). Body is divided into 4 areas for scoring (head, arms, trunk, legs; each area is scored by itself and scores are combined for final PASI. For each area, percent of skin involved is estimated: 0 (0%) to 6 (90-100%), and severity is estimated by clinical signs, erythema, induration and desquamation; scale 0 (none) to 4 (maximum). Final PASI = sum of severity parameters for each area\* area score weight of section (head: 0.1, arms: 0.2 body: 0.3 legs: 0.4). The IGA scale is static, i.e. it referred exclusively to the participant's disease at the time of the assessment, and did not compare with any of the participant's previous disease states at previous visits. The scores are: 0 = clear, 1 = almost clear, 2 = mild, 3 = moderate, 4 = severe and 5 = very severe.

Time frame: Extension weeks: 1, 25, 73 and 301 (too few data points were available to perform analysis at week 301)

Long-term Immunogenicity Assessed by the Number of Participants Developing Anti Secukinumab Antibodies During the Trial

Describes the number of participants tested positive for anti-secukinumab antibodies. It refers to the number of participants who had no positive values at baseline but developed them only after start of secukinumab treatment.

Time frame: up to week 351
