Multiple Sclerosis Clinical Trial

Official title: A run-in Study on the Safety and Tolerability of a Fasting Mimicking Diet in Relapsing Remitting Multiple Sclerosis (FAST-MS)

Status Active, not recruiting

Clinical Trial Summary

This study is an open-label, single-arm, run-in study in patients with RRMS treated with first line therapies (interferon-beta, glatiramer acetate, teriflunomide and dimethyl fumarate), assessing the feasibility and tolerability of 3 cycles of Fasting-Mimicking Diet (FMD) over 6 months. All eligible patients will receive 3 cycles of the FMD once every 60 days in addition to their standard therapy with first line therapies. The diet provides 1100kcal on day 1 and 800 kcal on days 2-7. The diet consists of ingredients which are Generally Regarded As Safe (GRAS) selected for their fasting mimicking properties.

Clinical Trial Description

The primary objective of the present study is to evaluate the safety and tolerability of 3 cycles of a 7 days FMD as a potential support to the management of patients affected by RRMS treated with first line therapies (interferon-beta, glatiramer acetate, teriflunomide and dimethyl fumarate). The primary endpoint is the number of serious and/or severe adverse events after the FMD start. A nutritionist will follow the patients for all the 6 months period, with the aim to monitor the FMD effects and to check for any possible problems. The nutritionist will call the patient on day 1 of every FMD cycle to answer any questions and check on the response, and on day 5 of the FMD to check on side effects and adherence.

At scheduled visits, vital signs and adverse events will be recorded from every patient.

Blood samples will be collected at baseline and just before at day 7 before returning to the normal diet on cycle 1 and 1 week after the first, the second and third FMD cycles. Should the patient display abnormal counts, the CBC will be repeated one week later. Additional FMD cycles will not be allowed in patients who do not return to normal levels of White Blood Cells (WBC) and Red Blood Cells (RBC).

At scheduled visits, vital signs and adverse events will be recorded from every patient.

FMD will be administered at month 0, month 2 and month 4 (3 cycles). MRI will be done at baseline and at month 6. At baseline and at month 6 patients will be evaluated with the EDSS and MSFC Functional composite scale. At the same time points, patients will be examined for the presence of cognitive disturbances by the Brief International Cognitive Assessment in Multiple Sclerosis (BICAMS) battery , of anxiety and depressive symptoms by the Hospital Anxiety and Depression Scale (HADS) , of fatigue by the Modified Fatigue Impact Scale (MFIS) , while quality of life will be monitored using the Short Form 36 Health Survey (SF-36) . A nutritional assessment will be carried out at enrollment and before every FMD cycle: patients will be examined evaluating the height and weight, with determination of the BMI; the bodily composition will be measured with a dynamometer and by BIA.

Adverse events (AEs) will be monitored for each patient up to the study termination; in case of ongoing AEs at study end, patients will be followed for 30 additional days.

During the whole duration of the study, patients will be instructed to perform standardized physical exercises, in order to avoid fasting induced sarcopenia. Briefly, before each FMD cycle, patients will be recommended to exercise 30 minutes daily according to a dedicated training program to improve their muscle anabolism in the interval between the three FMD cycles. ;
