NCT05083923

Brief Summary

The primary objectives of this study are to determine the safety and tolerability of DRF administered for up to 24 weeks in adult East Asian participants with RMS (Part 1) and to determine the safety and tolerability of DRF administered for up to 48 weeks in adult East Asian participants with RMS (Part 2). The secondary objective of this study is to evaluate the pharmacokinetic(s) (PK) of DRF metabolites (monomethyl fumarate \[MMF\] and 2-hydroxyethyl succinimide \[HES\]) following multiple doses of DRF in a subset of adult East Asian participants with RMS (Part 1).

Outcome Measures

Primary Outcomes (10)

  • Part 1: Number of Participants With Treatment Emergent Adverse Events (TEAEs) and Treatment Emergent Serious Adverse Events (TESAEs)

    An adverse event (AE) was any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether/not related to the medicinal (investigational) product. An AE was considered treatment-emergent if it starts or worsens on or after the date of the first dose of study drug in the study until 1 day after the last dose of treatment, or completion of the safety follow-up visit, if applicable.(i.e. for participants who prematurely discontinued study treatment or withdrew from the study) . An SAE is any untoward medical occurrence that at any dose results in death, is a life-threatening event, requires inpatient hospitalization or prolongation of existing hospitalization, results in a significant disability/incapacity or congenital anomaly, is a medically important event. TEAEs included both serious and non-serious TEAEs.

    Baseline (Day 1) up to Week 24 (for prematurely discontinued participants, AEs were reported up to 2 weeks post discontinuation)

  • Part 1: Number of Participants With Potentially Clinically Significant Abnormalities in Laboratory Parameters

    Laboratory assessments included hematology, blood chemistry, and urinalysis parameters. Hematology parameters:basophils, hematocrit, red blood cell, total and differential leukocytes, platelets, lymphocytes, monocytes, neutrophils, eosinophils, hemoglobin. Blood chemistry parameters:sodium, potassium, chloride, glucose, calcium, uric acid, total protein, albumin, creatine phosphokinase, Lipid profile: blood cholesterol,high-density lipoprotein,low-density lipoprotein, and triglycerides,serum follicle-stimulating hormone,Vitamin D,thyroid stimulating hormone,serum pregnancy, HIV/Hepatitis screen,tuberculosis test,alanine aminotransferase,aspartate aminotransferase,Lactate Dehydrogenase,alkaline phosphatase,gamma glutamyl transferase,total bilirubin,blood urea nitrogen,creatinine and bicarbonate. Urinalysis parameters:color,pH,specific gravity,ketones,protein,glucose, bilirubin,nitrite,urobilinogen,occult blood,microscopic examination,urine albumin,beta-2-microglobulin,urine creatinine.

    Baseline (Day 1) to Week 24

  • Part 1: Number of Participants With Abnormal Shift in 12-Lead Electrocardiogram (ECG) Values

    The number of participants with shifts to categorical values of ECG interpretation (e.g. abnormal) were presented by each cohort. Abnormal shift includes a shift from normal or unknown to abnormal.

    Baseline (Day 1) to Week 24

  • Part 1: Number of Participants With Clinically Relevant Abnormalities in Vital Sign Parameters

    Vital sign assessment included temperature, pulse rate systolic blood pressure, diastolic blood pressure, and respiratory rate. The criteria for determining potentially clinically relevant abnormalities in vital signs included: temperature \< 36 and \> 38 degrees Celsius (C), pulse rate \< 60 and \> 100 beats per minute (bpm), systolic blood pressure (\< 90, \> 140 and \> 160 millimeters of mercury \[mmHg\]), diastolic blood pressure \< 50, \> 90 and \> 100 mmHg, weight (7% or more increase from baseline, 7% or more decrease from baseline) and respiratory rate \< 12 and \> 20 breaths per minute.

    Baseline (Day 1) to Week 24

  • Part 1: Number of Participants With Columbia Suicide Severity Rating Scale (C-SSRS) Events

    The C-SSRS was an interview-based rating scale to systematically assess suicidal ideation, suicidal behavior and non-suicidal self-injurious behavior. The C-SSRS includes 'yes' or 'no' responses for assessment of suicidal behavior (preparatory acts or behavior, aborted attempt, interrupted attempt, Suicidal behavior, completed suicide), suicidal ideation (wish to be dead, non-specific active suicidal thoughts, active suicidal ideation with any methods, active suicidal ideation with some intent, active suicidal ideation with specific plan and intent) and non-suicidal self-injurious behavior.

    Baseline (Day 1) to Week 24

  • Parts 1 and 2: Number of Participants With TEAEs and TESAEs

    An AE was any unfavorable and unintended sign, symptom, or disease temporally associated with use of medicinal (investigational) product, whether/not related to medicinal (investigational) product. AE was considered treatment-emergent if it starts or worsens on or after the date of the first dose of study drug in the study until 1 day after the last dose of treatment. SAE is any untoward medical occurrence that at any dose results in death, is a life-threatening event, requires inpatient hospitalization or prolongation of existing hospitalization, results in a significant disability/incapacity or congenital anomaly, is a medically important event. TEAEs included both serious and non-serious TEAEs. TEAEs and TESAEs for participants were collected cumulatively for Parts 1 and 2.

    From Day 1 up to the end of the study (up to Week 50)

  • Part 2: Number of Participants With Potentially Clinically Significant Abnormalities in Laboratory Parameters
