About this study

Official title: An Open-label Clinical Trial of the Combination Treatment of Tacrolimus and Corticosteroid in Polymyositis/Dermatomyositis Patients With Interstitial Pneumonitis, With Comparison Against Corticosteroid-treated Historical Controls

The purpose of the study is to evaluate the efficacy and safety of the combination treatment of tacrolimus and corticosteroid in polymyositis/dermatomyositis patients with interstitial pneumonitis with comparison against corticosteroid-treated historical controls.

Read the detailed description

Interstitial pneumonia (IP) is a common complication of and has a significant impact on the prognosis of patients with polymyositis (PM) and dermatomyositis (DM). Reported prevalence of IP in PM/DM patients varies between 23 to 65% depending on criteria applied as well as on clinical settings of studied cohorts, and an earlier overview and a later study reported its high short-term mortality.

However, treatment for this grave complication has not yet been either established or even been prospectively investigated. Glucocorticoids, while long been considered as the first-line drugs, is effective in less than 50% of patients. Furthermore, the mortality of these glucocorticoids-resistant patients does not improve even if immunosuppressive drugs are later added.

Recently, we and others reported retrospective data which suggest that either an early addition of immunosuppressive drugs to glucocorticoids or the combined use of glucocorticoids and immunosuppressive drugs from the initial treatment may improve the survival of PM/DM patients. To save lives of PM/DM-IP patients, desperate treating physicians have started using this approach, strongly urging the conduct of prospective studies to investigate the superiority of this approach over glucocorticoids alone. At the same time, it was considered not ethically appropriate to conduct a prospective study with a concurrent controlled group receiving glucocorticoids alone given the presence of the PM/DM-IP subtype with rapidly progressive course and high short-term mortality if treated with glucocorticoids alone and the absence of useful demographic or bio-markers which could distinguish patients with this subtype early. Among immunosuppressive drugs used in the treatment of PM/DM-IP, tacrolimus has recently been suggested to be effective even for those patients who are resistant to cyclosporine or cyclosphosphamide.

To investigate whether the combined initial treatment of glucocorticoids and tacrolimus is superior to glucocorticoids alone in PM/DM-IP patients, we conducted a multicenter clinical trial to evaluate the efficacy and safety of a combination treatment of glucocorticoids and tacrolimus for 1 year in patients with newly developed active PM/DM-IP or its relapse by comparing against clinical outcome of historical control patients who were treated with glucocorticoid alone as an initial treatment.

What participants receive

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

  • TacrolimusDrug

    Also called Prograf

    Start at the standard starting dose of 0.075mg/kg/day divided into two doses, then adjust doses based on clinical response and tolerability, but maintain whole blood trough levels between 5 to 10 ng/mL and total daily doses equal to or below 0.3mg/kg.

Study groups in NCT00504348
Study groupRoleWhat they receive
Prospective investigation groupExperimentalTacrolimus treatment is to be initiated at the starting dose of 0.075mg/kg/day, adjusted to maintain its whole blood trough levels between 5 and 10 ng/mL for 52 weeks. All patients are to receive glucocorticoids with the starting doses equivalent to between 0.6 and 1.0 mg/kg/day of prednisolone which are to be continued for the first 28 days after which be subsequently tapered according to a predefined guideline. Up to two courses of pulse intravenous glucocorticoid therapy are allowed during that period.
Receives: Drug: Tacrolimus

What is being measured

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

  1. Overall Survival

    Overall survival (OS) was calculated from the day on which the protocol treatment was started until death due to any cause. Participants still alive were censored at the date they were last known to be alive.

    Measured: 52 weeks

Secondary outcomes (1)
  1. Progression-free Survival

    Patients were considered to have reached the progression if they died, or if they met all the following criteria; (1) ≥10% decline from baseline FVC or ≥15mmHg increase in baseline resting P(A-a)O2, (2) a worsening of interstitial pneumonitis findings by chest CT compared to the most recent study, confirmed by a radiologist, and (3) exclusion of pneumocystis pneumonia, cytomegalovirus pneumonia, and other pulmonary infection on clinical ground.

    Measured: 52 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Tacrolimus in people with Interstitial Pneumonitis and Polymyositis, run by Tokyo Medical and Dental University at 11 sites in Japan.

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 15 inclusion and 31 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 24 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 11 sites in Japan. 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 combined 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.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 24 Mar 2020). 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?

Overall Survival (time frame: 52 weeks). 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 NCT00504348, which also lists 1 linked publication.

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 24 Mar 2020.
