Trial Outcomes & Findings for A Study to Examine the Efficacy and Safety of REGN5069 in Patients With Pain Due to Osteoarthritis of the Knee (NCT NCT03956550)

NCT ID: NCT03956550

Last Updated: 2021-07-01

Results Overview

The WOMAC index is comprised of 24 parameters grouped in 3 subscales (pain-5 questions, physical function -17 questions and stiffness - 2 questions), with 0-10 grading of each question. The scores for each subscale are summed up, divided by number of questions, and each subscale is reported using Numerical Rating Scale score of 0-10. In addition to subscales, a total score is provided as the sum of normalized subscale scores divided by three, and reported using a Numerical Rating Scale score of 0-10. Higher scores indicate worse pain, stiffness and functional limitations.

Participant Flow

The study was conducted in 5 countries and 12 sites participated in enrollment. It consisted of screening period up to 30 days, followed by a 12-week randomized, double-blind, placebo-controlled treatment period, a 24-week follow-up period, and end-of-study phone call approximately 52 weeks after first dose. Study was terminated after all participants completed the week 36 visits.

A total of 259 participants were randomized in 1:1:1 ratio to receive REGN5069 at 100 mg IV Q4W, REGN5069 at 1000 mg IV Q4W, or matching placebo Q4W. Participants were to receive 3 fixed-dose IV infusions at baseline, week 4, and week 8. 171 participants were randomized to receive REGN5069 (86 participants in the 100 mg Q4W group and 85 in the 1000 mg Q4W group) and 88 were randomized to receive placebo.

The WOMAC index is comprised of 24 parameters grouped in 3 subscales (pain-5 questions, physical function -17 questions and stiffness - 2 questions), with 0-10 grading of each question. The scores for each subscale are summed up, divided by number of questions, and each subscale is reported using Numerical Rating Scale score of 0-10. In addition to subscales, a total score is provided as the sum of normalized subscale scores divided by three, and reported using a Numerical Rating Scale score of 0-10.

An adverse event (AE) is any untoward medical occurrence in a patient administered a study drug which may or may not have a causal relationship with the study drug. Treatment-emergent AEs (TEAEs) are AEs that developed or worsened during the treatment period.

Adjudicated arthropathy is an umbrella term referring to Rapidly Progressive Osteoarthritis Type 1 (RPOA-1), Rapidly Progressive Osteoarthritis Type 2 (RPOA-2), subchondral insufficiency fractures (SIF) and osteonecrosis (ON) confirmed by an arthropathy adjudication committee.

Population: Anti-Drug Antibody (ADA) Analysis Set: included all treated participants who received any amount of study drug (active or placebo \[safety analysis set (SAF)\]) and had at least one non-missing anti-REGN5069 antibody result following the first dose of study drug or placebo. ADA analysis set is based on actual treatment received, rather than randomized.

Immunogenicity will be characterized by ADA responses \& titers. Responses categories: Negative - ADA negative response at all time points, regardless of missing samples; Pre-existing immunoreactivity - ADA positive response at baseline with all post first dose negative results or positive response at baseline with all post first dose ADA responses \< 9-fold over baseline titer levels; Treatment-boosted response - positive response in the assay post first dose, ≥ 9-fold over baseline titer levels, when baseline results are positive; Treatment-emergent response - ADA positive response in the REG5069 ADA assay post first dose when baseline results = negative or missing.
