Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Has definite or probable DM based on the criteria of Bohan and Peter
  • Has a Cutaneous Dermatomyositis Disease Area and Severity Index (CDASI)-Activity score ≥15
  • Patients with muscle weakness are eligible; however having muscle weakness is not mandatory.
  • Study participants must have a diagnostic evaluation for cancer if the diagnosis of DM was within 2 years prior to the Screening Visit

Exclusion Criteria:

  • Has ongoing severe dysphagia (e.g., requires a feeding tube) for the 3 months prior to Screening
  • Has known hypersensitivity to any oligodeoxynucleotide
  • Has a history of drug or alcohol abuse within one year of screening, or evidence of drug abuse by urine drug screening
  • Has body weight >140 kg
  • Has a diagnosis of Juvenile DM, IBM, drug-induced toxic myopathy, metabolic myopathy, dystrophy, cancer-associated DM, or connective tissue disease-associated DM (e.g., overlap syndrome)

  • Has received one or more of following prohibited treatments within the interval noted prior to Screening (Visit 1):

    1. Rituximab within 24 weeks (Note: patients who received rituximab are only eligible for inclusion if B-cell counts are confirmed to be within normal limits)
    2. Intravenous corticosteroids within 12 weeks
    3. Antimalarials (e.g., hydroxychloroquine) within 36 weeks
    4. Topical corticosteroids (excluding scalp) within 2 weeks
  • Has evidence of or has required treatment for cancer (except for treated, non-invasive carcinoma of the skin or cured cervical carcinoma-in-situ) within 5 years

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
To Assess the Safety and Tolerability of IMO-8400 in Adult Subjects With DM
Time Frame: 28 weeks (24 weeks treatment + 4 weeks follow up)
Number of participants with different types of Treatment Emergent Adverse Events
28 weeks (24 weeks treatment + 4 weeks follow up)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in CDASI (Cutaneous Disease and Activity Severity Index) Activity Score
Time Frame: 28 weeks (24 weeks treatment + 4 weeks follow up)
Change from baseline in mCDASI (Cutaneous Disease and Activity Severity Index) v2-Activity score as measured at Visits 2, 6, 10, 14, 18, 22 and 26 (EOT/ Week 25). Index is Clinician administered one page instrument designed to evaluate the cutaneous manifestations of DM. CDASI yields a total score that captures overall disease state, an activity score (range:0-100) that reflects the current inflammatory state of disease and a damage score (range: 0-32). The CDASI includes separate measurements for disease activity and damage and yields a total score that captures overall disease state, an activity score that reflects the current inflammatory state of disease, and a damage score. Decreases in CDASI scores are indicative of improvement. In this study, Activity Scores were measured. The scores below are averaged.
28 weeks (24 weeks treatment + 4 weeks follow up)

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
