Pilot Study to Assess Dimethyl Fumarate Related GI Symptom Mitigation

Phase 4

Terminated

• Conditions: Relapsing Remitting Multiple Sclerosis
• Interventions: Drug: Simethicone; Drug: Loperamide; Other: Peanut Butter

• Registration Number: NCT02217982
• Lead Sponsor: Rocky Mountain MS Research Group, LLC

Brief Summary

Single site, open label, randomized design in patients with relapsing forms of Multiple Sclerosis. At the Screening Visit, the patient will be given a diary containing the MAGIS scale to be completed once a day for the first two weeks while on Dimethyl Fumarate (DMF), including the titration period.

After two weeks or if a patient experiences 3 or more consecutive days of GI symptoms in any category of ≥3.5, the patient will return for a Baseline Visit. The MAGIS diary will be reviewed by the coordinator. Any patient who has reported an average MAGIS score of greater than or equal to 3.5 in at least one of the key categories will be randomized to a standard therapy or treatment arm. Patients who report a MAGIS of less than 3.5 during this period will be terminated from the study at this visit. Patients with an average reported MAGIS of greater than 6.5 at Baseline will be placed in the treatment arm.

Patients who are randomized to the treatment arm will be instructed to take 125 mg simethicone and one tablespoon of a high fat food (peanut butter) 10 minutes prior to each DMF dose. If the average MAGIS score is greater than 3.5 in the diarrhea category they will also be instructed to take 2 mg loperamide three times daily.

Patients randomized to the standard therapy arm will be instructed to follow the normal dosing regimen for DMF with a food bolus of their choice prior to dosing. If severe symptoms (MAGIS \>6.5) are noted at any time post randomization in any MAGIS category, crossover to the treatment arm will be allowed. Both groups will be asked to rate their GI symptoms over the past 24 hours using the MAGIS scale once daily.

Both treatment arms will be observed for 6 weeks. MAGIS will be recorded once daily. Patients will return to the clinic at Week 3 and Week 6/End of Treatment for diary and compliance review. After Week 6, patients will be instructed to return to a standard therapy. MAGIS will be recorded for one more week and collected at Week 7/End of Study.

Arm && Interventions

Group	Intervention	Description
Treatment Arm	Peanut Butter	Patients who are randomized to the treatment arm will be instructed to take 125 mg simethicone and one tablespoon of a high fat food (peanut butter)10 minutes prior to each DMF dose. If the average MAGIS score is greater than 3.5 in the diarrhea category they will also be instructed to take 2 mg loperamide three times daily.
Treatment Arm	Simethicone	Patients who are randomized to the treatment arm will be instructed to take 125 mg simethicone and one tablespoon of a high fat food (peanut butter)10 minutes prior to each DMF dose. If the average MAGIS score is greater than 3.5 in the diarrhea category they will also be instructed to take 2 mg loperamide three times daily.
Treatment Arm	Loperamide	Patients who are randomized to the treatment arm will be instructed to take 125 mg simethicone and one tablespoon of a high fat food (peanut butter)10 minutes prior to each DMF dose. If the average MAGIS score is greater than 3.5 in the diarrhea category they will also be instructed to take 2 mg loperamide three times daily.

Primary Outcome Measures

Name	Time	Method
Reported GI Symptoms	7 Weeks	The primary endpoint will be severity of GI events as measured by the MAGIS scale for subjects in the treatment arm compared to the standard therapy arm.

Secondary Outcome Measures

Name	Time	Method
Diarrhea Reduction	7 Weeks	The secondary objective is to assess the reduction in diarrhea in the treatment group compared to the control.
