About this study

Official title: A Randomized, Double-Blind, Placebo-Controlled, Multi-Center Study to Evaluate the Superiority of CRx-102 Over Each of Its Components When Given to Subjects With Active Rheumatoid Arthritis (RA)

CRx-102 is a synergistic combination drug candidate containing the cardiovascular drug dipyridamole and a very low dose of the glucocorticoid prednisolone. CRx-102 is believed to work through a novel mechanism of action in which dipyridamole selectively amplifies the anti-inflammatory and immunomodulatory activities of the glucocorticoid without replicating the dose-dependent adverse effects. CRx-102 has been associated with clinical benefit in proof of concept studies in subjects with hand Osteoarthritis (OA) and Rheumatoid Arthritis (RA).

In this trial, CRx-102 will be given to subjects with active RA as an add-on therapy to existing stable doses of Disease Modifying Anti-Rheumatic Drugs (DMARDs) including methotrexate (MTX), sulfasalazine, hydroxychloroquine, leflunomide or azathioprine. MTX in combination with other DMARDs (e.g., sulfasalazine or hydroxychloroquine) will be permitted to reflect the current standard of care practices within rheumatology.

Read the detailed description

The study was discontinued before the enrollment objective was met. Preliminary review of the efficacy dataset revealed that the efficacy dataset was not robust enough to support an extensive formal efficacy analysis as described in the SAP. Therefore, only the CRP values over time and the percent change in C-reactive protein (CRP) values in the As-Treated population were calculated.

What is being measured

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

  1. Absolute C-reactive Protein (CRP) Values at Day 98 - As Treated Population

    Preliminary review of the efficacy dataset revealed that the efficacy dataset was not robust enough to support an extensive formal efficacy analysis as described in the SAP. Therefore, only the CRP values over time and the percent change in CRP values in the As-Treated population were calculated.

    Measured: Day 98

Secondary outcomes (3)
  1. Percent Change From Baseline to Day 98 in C-reactive Protein (CRP) Values - As Treated Population

    Preliminary review of the efficacy dataset revealed that the efficacy dataset was not robust enough to support an extensive formal efficacy analysis as described in the SAP. Therefore, only the CRP values over time and the percent change in CRP values in the As-Treated population were calculated.

    Measured: baseline to day 98

  2. To Assess the Superiority of CRx-102 Compared to Prednisolone and Dipyridamole Using American College of Rheumatology Rating Scale (20% or More Improvement; ACR20) Calculated From Baseline to Day 98 in Subjects With Active Rheumatoid Arthritis

    Preliminary review of the efficacy dataset revealed that the efficacy dataset was not robust enough to support an extensive formal efficacy analysis as described in the SAP. Therefore, only the CRP values over time and the percent change in CRP values in the As-Treated population were calculated.

    Measured: baseline to day 98

  3. To Assess the Efficacy of CRx-102 Compared to Placebo Using ACR 20 Calculated From Baseline to Day 98

    Preliminary review of the efficacy dataset revealed that the efficacy dataset was not robust enough to support an extensive formal efficacy analysis as described in the SAP. Therefore, only the CRP values over time and the percent change in CRP values in the As-Treated population were calculated.

    Measured: baseline to 98 Days

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing CRx-102 (2.7/180), prednisolone and dipyridamole in people with Rheumatoid Arthritis, run by Zalicus at 48 sites in 12 countries.

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 8 inclusion and 34 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 29 Apr 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 48 sites in United States, Poland, Argentina, Canada, Hungary and 7 more countries. 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. 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 29 Apr 2014). 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?

Absolute C-reactive Protein (CRP) Values at Day 98 - As Treated Population (time frame: Day 98). 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 29 Apr 2014.
