Eligibility criteria

Key Inclusion Criteria:

  • Diagnosis of IIM (DM or polymyositis [PM]) as per Bohan and Peter classification criteria
  • MMT-8 ≤125 units and two out of the following CSM items, or MMT-8 >125 units and three out of the following CSM items, together with verifiable muscular weakness A. PGA VAS ≥2 cm B. SGA VAS ≥2 cm C. HAQ-DI ≥0.25 D. Extramuscular activity (MDAAT) ≥2 cm E. Increase in one or more muscle enzyme (CK, LDH, , ALT, aldolase) values (must be ≥1.3 × )
  • On treatment with standard of care ( and/or ) for >12 weeks and on stable therapy for at least 4 weeks

Key Exclusion Criteria:

  • Inclusion body myositis (IBM) or amyopathic DM
  • Severe muscle damage (myositis damage index [MDI] >7/10 cm). Permanent deterioration caused by reasons other than PM/DM, or myositis with cardiac involvement
  • renal/hepatic impairment
  • Severe interstitial lung disease requiring supportive oxygen therapy
Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Sep 2023 (actual). Primary completion is estimated for Mar 2025, 18 months after the start.

Of 19 phase 2 interventional studies under Dermatomyositis, half reached primary completion within 31 months of starting (the median), counting those still running; a quarter within 28 and three quarters within 52. This study's planned 18 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 13, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
