About this study

Official title: A Phase II, Placebo-Controlled, Multicenter, Dynamic Randomized, Double Blind Trial of RC18, a Recombinant Human B Lymphocyte Stimulating Factor Receptor-Antibody Fusion Protein in Subjects With Inadequate Response of TNF-α Antagonists Due to Treat Moderate and Severe Rheumatoid Arthritis

This is a phase Ⅱ, placebo-controlled, multicenter, dynamic randomized, double blind study of the efficacy and safety of RC18, a recombinant human B lymphocyte stimulating factor receptor-antibody fusion protein in subjects with inadequate response of TNF-α antagonists due to treat moderate and severe rheumatoid arthritis.

Being tested
Placebo plus MTX, RC18 160 mg plus MTX
Medical subject headings
Lymphoma, Follicular, Arthritis, Rheumatoid

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Placebo plus MTXDrug

    Also called MTX=Methotrexate

    All patients had a foundation MTX therapy.The researchers evaluated the efficacy of the patient in 12 week.study investigator evaluate the patients of curative effect . The researchers evaluated the efficacy of the patient in 12 week.Evaluation of efficacy in patients if not get the ACR20 response, adjust the treatment plan given the test drug.Test group continue to the test drug,placebo group switch to the test drug.

  • RC18 160 mg plus MTXDrug

    Also called RC18, MTX=Methotrexate

What is being measured

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

  1. The proportion of patients in each group reached ACR20 24 weeks for visits

    ACR20 response: Patients with tenderness and swollen joint counts and 20% improvement,At least 3 20% improvement in the following 5:a.Health Assessment Questionnaire;b.Subjects assessed pain VAS score;c.Assess the overall situation of the disease subject VAS score;d.Researchers assessed the overall situation of the disease in the VAS score;e.Acute phase reactants(ESR or CRP)

    Measured: Week 24（Visit 9 ）

Secondary outcomes (1)

  1. Percentage of Participants Achieving a Clinically Meaningful Improvement in Disease Activity Score 28 (DAS28)at week 12 and week 24.

    DAS28 was calculated from the tender joint count (TJC) of 28 joints, swollen joint count (SJC) of 28 joints, erythrocyte sedimentation rate (ESR) (in millimeters [mm]/hour), and the participant's global assessment of disease activity (100 mm visual analog scale [VAS]: 0 mm=no disease activity to 100 mm=maximum disease activity). The formula for calculating DAS28 score using ESR value is: 0.56*square root (√) of TJC + 0.28*√(SJC) + 0.70*log natural (ESR) + 0.014*global assessment of disease activity (100 mm VAS). The DAS28 scale ranges from 0 to 10, where higher scores represent higher disease activity.

    Measured: week 12 and week 24

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing RC18 160 mg plus MTX in people with Moderate and Severe Rheumatoid Arthritis, run by RemeGen Co., Ltd. at 1 site in China.

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 24 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 3 Apr 2019. 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 China. 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?

The study was stopped early (reason given: Lack of trial population, unable to recruit subjects). Results are not available in the source record.

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?

The proportion of patients in each group reached ACR20 24 weeks for visits (time frame: Week 24（Visit 9 ）). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02882087.

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 3 Apr 2019.
