About this study
Official title: A Multicenter, Randomized, Double-Blind, Placebo-Controlled Phase 3 Trial to Evaluate Efficacy and Safety of Lenabasum in Dermatomyositis
This is a Phase 3 multicenter, double-blind, randomized, placebo-controlled study assessing the efficacy and safety of lenabasum for the treatment of dermatomyositis. Approximately 150 subjects will be enrolled in this study at about 60 sites in North America, Europe, and Asia. The planned duration of double-blind treatment with study drug is up to 52 weeks.
Read the detailed description
Subjects will be randomized to receive lenabasum 20 mg twice per day, lenabasum 5 mg twice per day, or placebo twice per day in a 2:1:2 ratio. The primary efficacy outcome at Week 28 will compare lenabasum 20 mg BID to placebo the Total Improvement Score (TIS), which is a weighted composite measure of improvement from baseline in six endpoints: Physician Global Assessment of Disease Activity, Physician Assessment of Extramuscular Disease Activity, Patient Global Assessment of Disease Activity, Health Assessment Questionnaire (patient-reported disability), Manual Muscle Testing (MMT), and muscle enzymes.

| Study group | Role | What they receive |
|---|---|---|
| Lenabasum 20 mg | Experimental | Subjects will receive lenabasum 20 mg twice daily Receives: Drug: Lenabasum 20 mg |
| Lenabasum 5 mg | Experimental | Subjects will receive lenabasum 5 mg twice daily Receives: Drug: Lenabasum 5 mg |
| Placebo | Placebo comparator | Subjects will receive placebo twice daily Receives: Drug: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Efficacy of lenabasum 20 mg BID compared to placebo BID as measured by Total Improvement Score (TIS)
TIS from IMAC Core Set Measures (CSM) will be calculated following Aggarwal et al (2017) recommendations. Scores are based on a 0 - 100 scale; higher scores indicate better improvement in myositis.
Measured: Week 28
Secondary outcomes (9)
Subjects who achieve Definition of Improvement (DOI)
Defined as ≥ 3 of 6 core set measures improved by ≥ 20% (relative to Baseline) with no more than 2 core set measures worsening by ≥ 25% (MMT-8 may not decrease by ≥ 25% from baseline)
Measured: Week 28
Subjects who improve by at least one category on the Investigator Global Assessment (IGA) scale of skin activity
The IGA is used by the investigator to score overall skin disease on a 0 to 4 scale; higher scores indicate greater skin disease.
Measured: Week 28
Change in Cutaneous Dermatomyositis Disease Area and Severity Index (CDASI) activity score
CDASI is a validated outcome measure that systematically quantifies cutaneous DM disease activity and damage (Klein et al, 2007; Yassaee et al, 2010) Disease Activity Score is rated using three activity measures. The activity score ranges from 0 to 100. Higher scores indicate greater disease severity.
Measured: Week 28
Subjects who achieve TIS >= 40 (at least moderate improvement)
TIS from IMAC Core Set Measures (CSM) will be calculated following Aggarwal et al (2017) recommendations. Scores are based on a 0 - 100 scale; higher scores indicate better improvement in myositis.
Measured: Week 28
TIS in subjects receiving immunosuppressive therapies (including corticosteroids) for > 1 year at Baseline
TIS from IMAC Core Set Measures (CSM) will be calculated following Aggarwal et al (2017) recommendations. Scores are based on a 0 - 100 scale; higher scores indicate better improvement in myositis.
Measured: Week 52
Change in Forced vital capacity (FVC) absolute, in all subjects and those with interstitial lung disease (ILD) at Baseline.
ILD is defined as a history of fibrosis on chest x-ray, a history of ILD on CT of lungs, and/or FVC% predicted <80% at Screening or Visit 1
Measured: Week 28
Change in Forced vital capacity (FVC) percent predicted, in all subjects and those with interstitial lung disease (ILD) at Baseline.
ILD is defined as a history of fibrosis on chest x-ray, a history of ILD on CT of lungs, and/or FVC% predicted <80% at Screening or Visit 1
Measured: Week 28
TIS at Visit 10
TIS from IMAC Core Set Measures (CSM) will be calculated following Aggarwal et al (2017) recommendations. Scores are based on a 0 - 100 scale; higher scores indicate better improvement in myositis.
Measured: Week 52
TIS, lenabasum 5 mg BID versus placebo
TIS from IMAC Core Set Measures (CSM) will be calculated following Aggarwal et al (2017) recommendations. Scores are based on a 0 - 100 scale; higher scores indicate better improvement in myositis.
Measured: Week 28

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Lenabasum 20 mg and Lenabasum 5 mg in people with Dermatomyositis, run by Corbus Pharmaceuticals Inc. at 54 sites in 13 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 10 inclusion and 8 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 16 Aug 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 54 sites in United States, Japan, South Korea, Bulgaria, Germany and 8 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 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Efficacy of lenabasum 20 mg BID compared to placebo BID as measured by Total Improvement Score (TIS) (time frame: Week 28). 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 NCT03813160, 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 16 Aug 2022.
