About this study

Official title: Rheumatoid Arthritis Memory B Cells and Abatacept (RAMBA)

Single-Open Label Study to Assess Changes in the Immune Profile in Response to Treatment with Intravenous Abatacept Adults with Rheumatoid Arthritis who are Naive to Biologic Disease-Modifying Antirheumatic Drugs

Read the detailed description

The immune system of patients with Rheumatoid Arthritis (RA) is different from that of people who do not have RA. The purpose of this study is to examine participants' immune cells and proteins before initiation of study medication and after initiation of treatment with an approved therapy for RA, abatacept that will be given in combination with Methotrexate and/or anti-rheumatic drugs (DMARDS) that are approved for the treatment of RA. This study will assess whether participants have clinically responded to these medications. This assessment will also include a study of whether characteristics of participants' immune systems were changed by therapy with the study drug, abatacept.

Being tested
Abatacept, DMARDs
Medical subject headings
Arthritis, Rheumatoid

What participants receive

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

  • AbataceptDrug

    Abatacept for reconstitution and dilution prior to intravenous (IV) administration. Each single-use vial of Abatacept for injection provides 250-mg Abatacept, maltose (500 mg), monobasic sodium phosphate (17.2 mg), and sodium chloride (14.6 mg) for administration.

  • DMARDsDrug

    Patients will receive methotrexate or remain on pre-existing conventional synthetic disease-modifying anti-rheumatic drug (DMARD) if already prescribed.

Study groups in NCT03652961
Study groupRoleWhat they receive
Abatacept plus DMARDExperimentalAbatacept will be used concomitantly with standard of care disease-modifying anti-rheumatic drugs (DMARDs), other than tumor necrosis factor (TNF) antagonists or Janus kinase (JAK) inhibitors. Intravenous (IV) Abatacept will be administered as a 30-minute IV infusion utilizing weight range-based dosing: 1. Less than 60 kg: 500 mg 2. 60 to 100 kg: 750 mg 3. More than 100 kg: 1000 mg Following the initial IV Abatacept administration, an IV infusion will be given at Weeks 2 and 4 after the first infusion and every 4 weeks thereafter for a total of 7 Abatacept doses. Abatacept will be discontinued after 6 months in all patients. Patients who have flared or failed to achieve low disease activity at 6 months will exit the trial except for one post-study visit for lab work at 9 months. In patients who have achieved low disease activity, Abatacept will be held for 6 months or until a flare results while DMARD use is continued.
Receives: Drug: Abatacept; Drug: DMARDs

What is being measured

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

  1. CDAI Score

    Clinical Disease Activity Index (CDAI) is a composite index used to assess rheumatoid arthritis (RA) disease activity.

    The CDAI score is the sum of the Swollen 28-Joint Count (SJC28) + Tender 28-Joint Count (TJC) + Patient Global disease Activity (PGA, patient's assessment of overall RA disease activity on a scale 1-10 where 10 is maximal activity) + Evaluator's Global disease Activity (EGA, evaluator's assessment of overall RA disease activity on a scale 1-10 where 10 is maximal activity). The total score range is 2-76; higher scores (CDAI > 22) indicate HIgh Disease Activity.

    Measured: Day 1

  2. CDAI Score

    Clinical Disease Activity Index (CDAI) is a composite index used to assess rheumatoid arthritis (RA) disease activity.

    The CDAI score is the sum of the Swollen 28-Joint Count (SJC28) + Tender 28-Joint Count (TJC) + Patient Global disease Activity (PGA, patient's assessment of overall RA disease activity on a scale 1-10 where 10 is maximal activity) + Evaluator's Global disease Activity (EGA, evaluator's assessment of overall RA disease activity on a scale 1-10 where 10 is maximal activity). The total score range is 2-76; higher scores (CDAI > 22) indicate HIgh Disease Activity.

    Measured: Month 6

  3. DAS-28 CRP Score

    Disease Activity Score-28 for Rheumatoid Arthritis with CRP (DAS28-CRP) is a composite index used to assess rheumatoid arthritis (RA) disease activity.

    The DAS-28 CRP score is calculated based on the tender joint count (out of 28 evaluated joints), swollen joint count (out of 28 evaluated joints), Patient's Global Assessment of Disease Activity (scored on 11-point Likert scale from 0 [no disease activity] to 10 [maximum disease activity]), and high-sensitivity C-reactive protein levels (in mg/L). DAS28-CRP Scores range from 0 to 10; higher scores indicate more active disease.

    Measured: Month 3

  4. DAS-28 CRP Score

    Disease Activity Score-28 for Rheumatoid Arthritis with CRP (DAS28-CRP) is a composite index used to assess rheumatoid arthritis (RA) disease activity.

    The DAS-28 CRP score is calculated based on the tender joint count (out of 28 evaluated joints), swollen joint count (out of 28 evaluated joints), Patient's Global Assessment of Disease Activity (scored on 11-point Likert scale from 0 [no disease activity] to 10 [maximum disease activity]), and high-sensitivity C-reactive protein levels (in mg/L). DAS28-CRP Scores range from 0 to 10; higher scores indicate more active disease.

    Measured: Month 6

Secondary outcomes (2)

  1. DAS-28 CRP Score After Abatacept Hold

    Disease Activity Score-28 for Rheumatoid Arthritis with CRP (DAS28-CRP) is a composite index used to assess rheumatoid arthritis (RA) disease activity.

    The DAS-28 CRP score is calculated based on the tender joint count (out of 28 evaluated joints), swollen joint count (out of 28 evaluated joints), Patient's Global Assessment of Disease Activity (scored on 11-point Likert scale from 0 [no disease activity] to 10 [maximum disease activity]), and high-sensitivity C-reactive protein levels (in mg/L). DAS28-CRP Scores range from 0 to 10; higher scores indicate more active disease.

    Measured: Month 9

  2. CDAI Score After Abatacept Hold

    Clinical Disease Activity Index (CDAI) is a composite index used to assess rheumatoid arthritis (RA) disease activity.

    The CDAI score is the sum of the Swollen 28-Joint Count (SJC28) + Tender 28-Joint Count (TJC) + Patient Global disease Activity (PGA, patient's assessment of overall RA disease activity on a scale 1-10 where 10 is maximal activity) + Evaluator's Global disease Activity (EGA, evaluator's assessment of overall RA disease activity on a scale 1-10 where 10 is maximal activity). The total score range is 2-76; higher scores (CDAI > 22) indicate HIgh Disease Activity.

    Measured: Month 9

The record lists 1 site in United States. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 6 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?

CDAI Score (time frame: Day 1). The study lists 4 primary outcomes in all. 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 NCT03652961, which also lists 15 linked publications.

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 Jul 2024.
