About this study

Official title: A Phase IIa, Randomized, Double-Blind, Placebo-Controlled, Parallel-Group, Multicenter, Worldwide, Proof-of-Concept Clinical Trial to Evaluate the Safety, Tolerability, and Efficacy of MK-8457 in Subjects With Active Rheumatoid Arthritis and an Inadequate Response or Intolerance to Anti-TNF-α Therapy

The purpose of this study is to assess the safety and efficacy of MK-8457 + Methotrexate (MTX) in participants with active rheumatoid arthritis (RA) and an inadequate response or intolerance to anti-tumor necrosis factor α (anti-TNF-α) therapy. The primary hypothesis of this study is that among participants with active RA, MK-8457 100 mg twice daily (BID) + MTX will be superior to placebo + MTX as measured by the change in Disease Activity Score 28 C-Reactive Protein (DAS28-CRP) after 12 weeks of treatment.

Read the detailed description

In the Base Study, participants were to receive blinded MK-8457 100 mg + MTX or matched placebo + MTX for up to 24 weeks. At Week 12 and 18, efficacy evaluation was conducted to assess eligibility for early escape, defined as <20% improvement in tender and swollen joint counts. Participants who completed the Base Study and those eligible for early escape could enroll in the 76-week Safety Extension in which participants were to receive open-label MK-8457 100 mg BID + MTX.

All participants must have been treated with MTX for at least 3 months prior to Screening and have been receiving a stable dose of MTX for at least 4 weeks prior to Screening. In addition, each participant must have either failed treatment with 1 or 2 anti-TNF-α therapies or was intolerant to anti-TNF-α therapy prior to Screening. For participants who failed therapy, the treatment with anti-TNF-α therapies must have been for at least 3 months.

What is being measured

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

  1. Change From Baseline in Disease Activity Score (DAS28) as Measured by C-Reactive Protein (CRP) at Week 12

    The DAS28-CRP is a continuous parameter based upon a statistically-derived index combining tender joints (28 joints; 0=absent, 1=present; TEN28), swollen joints (28 joints; 0=absent, 1=present; SW28), CRP (an inflammatory marker, decrease indicates improvement), and Patient's Global Assessment of Disease Activity Visual Analog Scale (VAS) (0=doing very well to 100=doing very poor; GH). It is defined as follows: DAS28-CRP = 0.56 × SQRT(TEN28) + 0.28 × SQRT(SW28) + 0.36 × ln (CRP+1) + 0.014 × GH + 0.96. The DAS28-CRP is a scale ranging from 0 to 10 with higher values indicating greater RA disease activity. This outcome measure applied to Base Study participants only.

    Measured: Baseline and Week 12

Secondary outcomes (7)
  1. Percentage of Participants Achieving an American College of Rheumatology (ACR) 20 Response at Week 12

    ACR responses are numerical measurements of improvement in multiple disease assessment criteria. An ACR20 response is defined as a ≥20% improvement in 1) swollen joint count (66 joints) and tender joint count (68 joints) (0 = Absent; 1 = Present) and 2) ≥20% improvement in 3 of the following 5 assessments: a) a participant's overall assessment of pain on a visual analog scale (VAS, no pain =0 to extreme pain =100); b) Patient's Global Assessment of Disease Activity VAS (doing very well =0 to doing very poor =100); c) Investigator's Global Assessment of Disease Activity VAS (doing very well =0 to doing very poor =100 ; d) participant's assessment of function across 8 functional areas as measured by Health Assessment Questionnaire (HAQ), total scores ranging from no difficulty =0 to inability to perform tasks =24; and e) serum C-Reactive Protein (decrease indicates improvement). This outcome measure applied to Base Study participants only.

    Measured: Week 12

  2. Percentage of Participants Achieving an ACR20 Response at Week 24

    ACR responses are numerical measurements of improvement in multiple disease assessment criteria. An ACR20 response is defined as a ≥20% improvement in 1) swollen joint count (66 joints) and tender joint count (68 joints) (0 = Absent; 1 = Present) and 2) ≥20% improvement in 3 of the following 5 assessments: a) a participant's overall assessment of pain on a visual analog scale (VAS, no pain =0 to extreme pain =100); b) Patient's Global Assessment of Disease Activity VAS (doing very well =0 to doing very poor =100); c) Investigator's Global Assessment of Disease Activity VAS (doing very well =0 to doing very poor =100 ; d) participant's assessment of function across 8 functional areas as measured by Health Assessment Questionnaire (HAQ), total scores ranging from no difficulty =0 to inability to perform tasks =24; and e) serum C-Reactive Protein (decrease indicates improvement). This outcome measure applied to Base Study participants only.

    Measured: Week 24

  3. Percentage of Participants Achieving an ACR50 Response at Week 12

    ACR responses are numerical measurements of improvement in multiple disease assessment criteria. An ACR50 response is defined as a ≥50% improvement in 1) swollen joint count (66 joints) and tender joint count (68 joints) (0 = Absent; 1 = Present) and 2) ≥50% improvement in 3 of the following 5 assessments: a) a participant's overall assessment of pain on a visual analog scale (VAS, no pain =0 to extreme pain =100); b) Patient's Global Assessment of Disease Activity VAS (doing very well =0 to doing very poor =100); c) Investigator's Global Assessment of Disease Activity VAS (doing very well =0 to doing very poor =100 ; d) participant's assessment of function across 8 functional areas as measured by Health Assessment Questionnaire (HAQ), total scores ranging from no difficulty =0 to inability to perform tasks =24; and e) serum C-Reactive Protein (decrease indicates improvement). This outcome measure applied to Base Study participants only.

    Measured: Week 12

  4. Change From Baseline in DAS28-CRP at Week 24

    The DAS28-CRP is a continuous parameter based upon a statistically-derived index combining tender joints (28 joints; 0=absent, 1=present; TEN28), swollen joints (28 joints; 0=absent, 1=present; SW28), CRP (decrease indicates improvement), and Patient's Global Assessment of Disease Activity Visual Analog Scale (VAS) (0=doing very well to 100=doing very poor; GH, ). It is defined as follows: DAS28-CRP = 0.56 × SQRT(TEN28) + 0.28 × SQRT(SW28) + 0.36 × ln (CRP+1) + 0.014 × GH + 0.96. The DAS28-CRP is a scale ranging from 0 to 10 with higher values indicating greater RA disease activity. This outcome measure applied to Base Study participants only.

    Measured: Baseline and Week 24

  5. Change From Baseline in the Health Assessment Questionnaire Disability (HAQ Disability Index) at Week 12

    The functional status of the participant was assessed using the Disability Index of the HAQ on a Likert scale. This 20-question instrument assesses the degree of difficulty a person has in accomplishing tasks in 8 functional areas (dressing, arising, eating, walking, hygiene, reaching, gripping, and activities of daily living). Responses in each functional area are scored from 0, indicating no difficulty, to 3, indicating inability to perform a task in that area. The overall score for the Disability Index is the mean of the 8 functional area scores and also ranges from 0 to 3, with a lower score indicating less disability. A negative change from Baseline indicates improvement. This outcome measure applied to Base Study participants only.

    Measured: Baseline and Week 12

  6. Percentage of Participants Achieving an ACR50 Response at Week 24

    ACR responses are numerical measurements of improvement in multiple disease assessment criteria. An ACR50 response is defined as a ≥50% improvement in 1) swollen joint count (66 joints) and tender joint count (68 joints) (0=Absent; 1=Present) and 2) ≥50% improvement in 3 of the following 5 assessments: a) a participant's overall assessment of pain on a visual analog scale (VAS, 0=no pain to 100=extreme pain); b) Patient's Global Assessment of Disease Activity VAS (0=doing very well to 100=doing very poor); c) Investigator's Global Assessment of Disease Activity VAS (0=doing very well to 100=doing very poor; d) participant's assessment of function across 8 functional areas as measured by Health Assessment Questionnaire (HAQ), total scores ranging from 0=no difficulty to 24=inability to perform tasks; and e) CRP (decrease indicates improvement).

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing MK-8457 100 mg and Methotrexate in people with Rheumatoid Arthritis, run by Merck Sharp & Dohme LLC.

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 9 inclusion and 12 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: stopped early, as of the sponsor's last update on 30 Jul 2021. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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 23 Feb 2017). 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 From Baseline in Disease Activity Score (DAS28) as Measured by C-Reactive Protein (CRP) at Week 12 (time frame: Baseline and Week 12). 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 30 Jul 2021; AzTrials last refreshed its copy on 30 Oct 2026.
