Evaluation of the Efficacy and Safety of Two Dosing Regimens of Olokizumab (OKZ), Compared to Placebo and Adalimumab, in Subjects With Rheumatoid Arthritis (RA) Who Are Taking Methotrexate But Have Active Disease (CREDO 2)

September 19, 2023 updated by: R-Pharm International, LLC

A Randomized, Double-Blind, Parallel-Group, Placebo- and Active-Controlled, Multicenter Phase III Study of the Efficacy and Safety of Olokizumab in Subjects With Moderately to Severely Active Rheumatoid Arthritis Inadequately Controlled by Methotrexate Therapy

The purpose of this study was to determine how effective and safe the study drug Olokizumab was in patients with Rheumatoid Arthritis (RA) who had been already receiving but not fully responding to treatment with methotrexate (MTX).

The primary objective of this study was to evaluate the efficacy of OKZ 64 mg administered subcutaneously (SC) once every 2 weeks (q2w) or once every 4 weeks (q4w) relative to placebo in subjects with moderately to severely active RA inadequately controlled by MTX therapy.

The secondary objective was to evaluate the efficacy of OKZ relative to adalimumab in subjects with moderately to severely active RA inadequately controlled by MTX therapy.

Study Overview

Detailed Description

The goal of this Phase III study was to assess the efficacy, safety and tolerability of OKZ in subjects with moderately to severely active RA who had responded inadequately to MTX. The primary endpoint of the trial was at Week 12. Olokizumab was expected to reduce the disease activity and improve physical function. The study was expected to provide safety information in a large group of subjects over at least a 24 week period.

This study included a 4-week Screening Period, a double-blind Treatment Period from Week 0 to Week 24, and a Safety Follow-Up Period from Week 24 to Week 44. Subjects were assessed for eligibility to enter the study during the 4-week Screening Period. A total of 1575 subjects were planned to be randomly assigned to 1 of 4 treatment groups in a 2:2:2:1 ratio (450, 450, 450, and 225 subjects per group, respectively):

  1. Olokizumab 64 mg q4w: SC injection of OKZ 64 mg q4w (alternating with SC injection of placebo q4w to maintain blinding) + MTX
  2. Olokizumab 64 mg q2w: SC injection of OKZ 64 mg q2w + MTX
  3. Adalimumab 40 mg q2w: SC injection of adalimumab 40 mg q2w + MTX
  4. Placebo: SC injection of placebo q2w + MTX

Throughout the double-blind Treatment Period, all subjects were required to remain on a stable dose of background MTX with a stable route of administration. Concomitant treatment with folic acid was required for all subjects. The last dose of study treatment (OKZ, adalimumab, or placebo) was at Week 22 in all groups.

Following Visit 2 (randomization; Week 0), subjects returned to the study site at least every 2 weeks through Week 24 for response and safety assessments.

At Week 14, subjects who had not improved by at least 20% in both swollen and tender joint counts were classified as nonresponders and were administered sulfasalazine and/or hydroxychloroquine as rescue medication in addition to the assigned treatment.

After completion of the 24-week double-blind Treatment Period, subjects either rolled over into the long-term open-label extension (OLE) study or entered the Safety Follow-Up Period. During the Safety Follow-Up Period, subjects returned for visits +4, +8, and +22 weeks after the last dose of study treatment.

Subjects who had discontinued randomized treatment prematurely were required to come for the End of Treatment (EoT) Visit 2 weeks after the last study treatment administration and then continue with the scheduled study visits.

Adverse events (AEs) were assessed throughout the study (starting when the subject signed the informed consent form) and evaluated using the Common Terminology Criteria for Adverse Events Version 4.0. There was ongoing monitoring of safety events, including laboratory findings, by the Sponsor or the Sponsor's designee. In addition, safety was assessed throughout the study by an independent Data Safety Monitoring Board and potential major adverse cardiac events were evaluated by an independent Cardiovascular Adjudication Committee.

The study was conducted at 208 sites across 18 countries globally (in US, European Union (EU),United Kingdom (UK), Russian Federation, Asia, Latin America).

    • ≥6 tender joints (68 joint count) at Screening and baseline; and
    • ≥6 swollen joints (66 joint count) at Screening and baseline; and
    • CRP above the normal range (ULN) at Screening based on the central laboratory results.

Exclusion Criteria:

  • Diagnosis of any other inflammatory arthritis or systemic rheumatic disease (eg, gout, psoriatic or reactive arthritis, Crohn's disease, Lyme disease, juvenile idiopathic arthritis, or systemic lupus erythematosus). However, subjects could have secondary Sjogren's syndrome or hypothyroidism.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame

Time Frame: at Week 12

The difference between OKZ and placebo in the percentage of subjects achieving an ACR20 response and remaining on randomized treatment and in the study at Week 12. (where a responder was defined as any subject satisfying ACR20 criteria and remaining on randomized treatment and in the study at Week 12) This endpoint served to demonstrate that the efficacy of OKZ was superior to placebo. American College of Rheumatology 20 % response is a composite defined as a ≥ 20% improvement from baseline in the swollen joint counts assessed in 66 joints and in the tender joint count assessed in 68 joints; and a ≥20% improvement from baseline in at least 3 of the 5 remaining core set measures:

  • Patient Global Assessment of Disease Activity (VAS)
  • Patient Assessment of Pain (VAS)

at Week 12
Percentage of Subjects Achieving ACR20 Response: Olokizumab Comparison With Adalimumab
Time Frame: at Week 12

A responder was defined as any subject satisfying ACR20 criteria and remaining on randomized treatment and in the study at Week 12.This endpoint served to demonstrate that the efficacy of OKZ was non-inferior to adalimumab, provided that superiority of adalimumab to placebo (assay sensitivity) was demonstrated concurrently based on the same endpoint.

American College of Rheumatology 20 % response is a composite defined as a ≥ 20% improvement from baseline in the swollen joint counts assessed in 66 joints and in the tender joint count assessed in 68 joints; and a ≥20% improvement from baseline in at least 3 of the 5 remaining core set measures:

  • Patient Global Assessment of Disease Activity (VAS)
  • Patient Assessment of Pain (VAS)
  • HAQ-DI
  • Physician Global Assessment (VAS)
  • Level of acute phase reactant (CRP)
at Week 12
Percentage of Subjects Achieving Low Disease Activity: Olokizumab Comparison With Adalimumab
Time Frame: at Week 12
Percentage of subjects achieving low disease activity, defined as DAS28 (CRP) <3.2, and remaining on randomized treatment and in the study at Week 12; served to demonstrate that the efficacy of OKZ was noninferior to adalimumab, provided that superiority of adalimumab to placebo (assay sensitivity) was demonstrated concurrently based on the same endpoint
at Week 12
Improvement of Physical Ability From Baseline to Week 12, as Measured by the Health Assessment Questionnaire-Disability Index (HAQ-DI)
Time Frame: Baseline to Week 12
Change of physical ability from baseline (the last available assessment prior to the first dose of the study treatment) to week 12, as measured by HAQ-DI. The HAQ-DI assesses the degree of difficulty experienced in 8 domains of daily living activities using 20 questions.The domains are dressing and grooming, arising, eating, walking, hygiene, reach, grip and common daily activities, and each domain consists of 2 or 3 items. For each question, the level of difficulty is scored from 0 to 3 where 0 = without any difficulty (the best outcome), 1 = with some difficulty, 2 = much difficulty, and 3 = unable to do (the worst outcome). Each category is given a score by taking the maximum score of each question. A decrease from baseline indicates improvement for HAQ-DI.The HAQ-DI was calculated by dividing the sum of the category scores by the number of categories with at least 1 question answered. The HAQ-DI total score ranges from 0 (the best outcome) to 3 (the worst outcome).
Baseline to Week 12
Percentage of Subjects Achieving American College of Rheumatology 50% (ACR50) Response
Time Frame: at Week 24

Difference between OKZ and placebo in the percentage of subjects achieving an ACR50 response and remaining on randomized treatment and in the study at Week 24

American College of Rheumatology 50% Response is a composite defined as ≥50%, improvement from baseline in the swollen joint counts assessed in 66 joints and in the tender joint count assessed in 68 joints; and a ≥50%, improvement from baseline in at least 3 of the 5 remaining core set measures:

  • Patient Global Assessment of Disease Activity (VAS)
  • Patient Assessment of Pain (VAS)
  • HAQ-DI
  • Physician Global Assessment (VAS)
  • Level of acute phase reactant (CRP)
at Week 24
Percentage of Subjects With Clinical Disease Activity Index (CDAI) ≤ 2.8 (Remission)
Time Frame: at Week 24
Difference between OKZ and placebo in the percentage of subjects with Clinical Disease Activity Index (CDAI) ≤2.8 (remission) and remaining on randomized treatment and in the study at Week 24
