About this study

Official title: A Double-blind, Randomized, Multicenter, Noninferiority, Phase II Repeat Dose Study of CG100649 Versus Celecoxib in Osteoarthritis Patients

This is a double-blind, randomized, multicenter, phase 2b, noninferiority comparison of two active dose levels of CG100649 vs. a standard anti-arthritic dose of celecoxib (Celebrex).

Read the detailed description

This is a double-blind, randomized, multicenter, noninferiority, phase 2 study. Subjects will discontinue current medications (NSAID or COX-2 inhibitor) 5-14 days prior to randomization. Paracetamol (acetaminophen; ≤2 gm/day) may be used for breakthrough pain. Other NSAIDs, COX-2 inhibitors, opioids, and corticosteroids may not be used at any time during this study. Only subjects recording average WOMAC pain score of 4 to 8 on a 0-10 numerical rating scale during the washout period and meeting all other inclusion criteria will be randomized into the study.

Male and female adults, ages 20 and older, with a history of osteoarthritis (OA) of the knee or hip diagnosed by radiograph obtained within the past 20 years and with pain at least 3 months from OA can participate in this study. OA must be confirmed by radiographs and diagnosed according to American College of Rheumatology (ACR) guidelines. Subjects must qualify as ACR global functional status I, II, or III (excluding IV) and Kellgren-Lawrence grade 1, 2 or 3 (excluding grade 4).

Subjects meeting screening criteria will be randomized to receive 28 days dosing of an active dose of CG100649 or comparator (celecoxib).

Antiarthritic efficacy will be evaluated by changes in the Western Ontario and McMaster Universities (WOMAC) OA index completed on Day 1 (Baseline) and on Days 14, 28 and 42. The WOMAC pain subscale will be evaluated at screening and on Days 1, 7, 14, 21, 28, 35 and 42.

All doses will be administered orally once daily in the morning. There are 3 planned treatment arms (2 with active compound + one comparator (celecoxib) group) with n=44 per treatment arm. Total number of subjects will be 132.

Treatment A: CG100649: 2 mg/day (Days 1-28); Treatment B: CG100649: 4 mg/day (Days 1-28); Treatment C: celecoxib: 200 mg/day (Days 1-28); Active and comparator medications will have identical appearance.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change of the WOMAC Pain Subscale at Day 28 From Baseline

    Changes in the WOMAC Pain Score from Baseline The primary endpoint of this study was the change in the sum of the WOMAC Pain subscale at Day 28 vs. Baseline (Day 1) using the ITT population). Pain scores were evaluated using the WOMAC Pain subscale, which provided an evaluation of pain during the past 48 hours using a 0-10 numerical rating scale for each of 5 questions (minimum total: 0 point, maximum total: 50 points). A higher WOMAC Pain score represented worse symptom severity.

    Measured: Baseline, Day 28

Secondary outcomes (3)
  1. Change of the Sum of WOMAC OA Index at Day 28 From Baseline

    The numerical rating scale version of the Western Ontario and McMaster Universities (WOMAC) OA index will be used-i.e., with the patient assessing each question by a 11-point (0-10) numerical rating scale, and the total index score being represented by the sum of the 24 component item scores. A higher WOMAC score represents worse symptom severity, with 240 being the worst possible total score (minimum total: 0 point, maximum total: 240 points).

    Measured: Baseline, Day 28

  2. Change of WOMAC-Stiffness Subscale at Day 28 From Baseline

    Version 3.1 of the WOMAC knee and hip osteoarthritis index translated in Korean language was used to evaluate the stiffness of the index joint. Two questions were to evaluate "Stiffness" of the index joint. A higher WOMAC-Stiffness score represents worse symptom severity, with 20 being the worst possible total score (minimum total: 0 point, maximum total: 20 points).

    Measured: Baseline, Day 28

  3. Change of WOMAC-Physical Function Subscale at Day 28 From Baseline

    Version 3.1 of the WOMAC knee and hip osteoarthritis index translated in Korean language was used. The total 17 questions to evaluate "Physical Function." A higher score of WOMAC-Physical function subscale represents worse symptom severity, with 170 being the worst possible total score (minimum total: 0 point, maximum total: 170 points).

    Measured: Baseline, Day 28

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing CG100649 and Celecoxib in people with Osteoarthritis, run by CrystalGenomics, Inc. at 1 site in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 9 Feb 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 9 Feb 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change of the WOMAC Pain Subscale at Day 28 From Baseline (time frame: Baseline, Day 28). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Feb 2023.
