Dietary Supplement of Curcumin in Subjects With Active Relapsing Multiple Sclerosis Treated With Subcutaneous Interferon Beta 1a

Phase 2

Completed

Conditions: Multiple Sclerosis

Interventions: Drug: IFN beta 1a 44 mcg TIW
Drug: Placebo
Drug: Curcumin

Registration Number: NCT01514370

Lead Sponsor: Merck KGaA, Darmstadt, Germany

Brief Summary: This is a prospective, monocentric, double blind, placebo controlled, two arm study.

Curcumin is derived from the rhizomes of the plant Curcuma longa (common name, turmeric) belonging to the Zingiberaceae family found in South Asian countries, especially India which is the largest producer. BCM95 (bioCurcumin) is a combination of a Curcumin extract and oil to enhance the bio-absorbability in humans. BCM95 may enhance and prolong the antioxidant and anti-inflammatory effects of the standard therapy maintaining a good safety profile.

Detailed Description: The subjects must experience at least one Gadolinium (GD) enhancing Magnetic Resonance Imaging (MRI) lesion at the baseline visit or one Multiple Sclerosis (MS) relapse in the last 6 months before the screening visit.

Randomization, in a 1:1 ratio, will be done with two arms:

40 subjects with Interferon (IFN) beta 1 a 44 mcg TIW + Curcumin (BCM 95) and 40 subjects with IFN beta-1a 44 mcg TIW + placebo.

The study will last 42 months: 18 months of enrolment and 24 months of treatment period.

The study consists of 6 visits per subject: screening visit (Visit 0), baseline (Visit 1), a visit 3 months after baseline (Visit 2), 6 months after baseline (Visit 3), 12 months after baseline (Visit 4) and 24 months after baseline (Visit 5).

Primary Outcome Measures

Name	Time	Method
Number of Subjects With Active (New or Enlarging) T2 Lesions Assessed by Magnetic Resonance Imaging (MRI) at Month 12	Month 12	A single T2 lesion was defined as an area of increased signal on a given 3-millimeters axial image that was not referable to normally hyperintense structures. New T2 lesions were those that appear in areas where on the previous scan no abnormality was detected. All T2 lesions were detected by an MRI scan.

Secondary Outcome Measures

Name	Time	Method
Median Change From Baseline in Regional Brain Volume at Month 12 and 24	Baseline, Month 12 and 24	Brain tissue volumes are inter-related and represent a measure of neurodegenerative aspects of the disease.
Annualized Relapse Rate at Month 12 and 24	Month 12 and 24	Relapse was defined as the development of new or the exacerbation of existing neurological symptoms or signs, in the absence of fever, lasting for 24 hours and with a previous period for more than 30 days with a stable or an improving condition. Annualized relapse rate was calculated by dividing the total number of relapse events by the total number of days subjects participated in the study. This number was then multiplied by 365.25 to get an annualized rate.
Total Number of Reported Relapses at Month 3, 6, 12 and 24	Month 3, 6, 12 and 24	Relapse was defined as the development of new or the exacerbation of existing neurological symptoms or signs, in the absence of fever, lasting for 24 hours and with a previous period for more than 30 days with a stable or an improving condition.
Percentage of Subjects Treated With Glucocorticoids Due to Relapses During 24 Months	Baseline up to Month 24	Relapse was defined as the development of new or the exacerbation of existing neurological symptoms or signs, in the absence of fever, lasting for 24 hours and with a previous period for more than 30 days with a stable or an improving condition. Percentage of subjects treated with glucocorticoids due to relapses during 24 Months were reported here.
Percentage of Relapse-Free Subjects at Month 12 and Month 24	Month 12 and 24	Relapse was defined as the development of new or the exacerbation of existing neurological symptoms or signs, in the absence of fever, lasting for 24 hours and with a previous period for more than 30 days with a stable or an improving condition.
Percentage of Subjects With Active (New/Enlarging) T2 Lesions at Month 24	Month 24	A single T2 lesion was defined as an area of increased signal on a given 3-millimeters axial image that was not referable to normally hyperintense structures. New T2 lesions were those that appear in areas where on the previous scan no abnormality was detected. All T2 lesions were detected by an MRI scan.
Percentage of Subjects Free From Expanded Disability Status Scale (EDSS) Progression at Month 12 and 24	Month 12 and 24	Disability progression was assessed using EDSS. EDSS is based on a standardized neurological exam and focuses on symptoms that commonly occur in multiple sclerosis (MS) . Overall scores ranges from 0.0 (normal) to 10.0 (death due to MS). Disability progression was defined as an increase of EDSS score of at least 1.0 point compared to baseline for subjects with an EDSS =\< 4.0. For subjects with an EDSS= 0 at baseline, EDSS progression was defined as an increase of EDSS score of at least 1.5 point. Percentage of subjects free from EDSS progression at Month 12 and 24 were reported
Hazard Ratio for Time to First Sustained Expanded Disability Status Scale (EDSS) Progression	Baseline to date at which the first confirmed EDSS progression occurs, assessed up to 24 months	EDSS progression is based on a standardized neurological exam and focuses on symptoms that commonly occur in MS. Overall scores ranges from 0.0 (normal) to 10.0 (death due to MS). A sustained progression on EDSS score was defined as an EDSS progression confirmed into two consecutive assessment. EDSS values obtained during clinical attacks are not excluded for the assessment of EDSS progression. However, EDSS values obtained during MS attacks that are not confirmed after two consecutive assessments will be excluded from statistical analysis of confirmed EDSS progression. Hazard ratio for time to first sustained EDSS progression was planned to be reported as per SAP.
Flu-like Symptoms (FLS) Assessed by FLS Scale Score	Screening, Baseline, Month 3, 6, 12 and 24	Flu-like symptoms were measured using FLS score in which subjects were scored as per the presence and intensity of muscle aches, chills, and weakness, each separately, on a scale of 0-3 as follows: 0 = absent; 1 = mild, do not interfere with daily activities; 2 = moderate, sufficient to interfere with daily activities; and 3 = severe, bed rest require. Body temperature also was also recorded to determine the presence of fever using the following scale: 0 (≤ 37.2 °C); 1 (≥ 37.3 °C but \< 37.8 °C); 2 (≥ 37.8 but \< 38.4 °C); and 3 (≥ 38.4 °C).The scores for each symptom (muscle aches, chills, weakness, body temperature) was added together to provide the combined flu-like symptom score ranging from 0 to 12 where 0 indicates absence of any symptom and 12 indicates the worst severity of the symptoms.
Number of Subjects With Treatment Emergent Adverse Event (TEAE), Serious AE (SAE), TEAE Leading to Death and Discontinuation	Baseline up to Month 24	AE was defined as any untoward medical occurrence which does not necessarily have a causal relationship with the study drug. An AE was defined as any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of study drug, whether or not considered related to the study drug. A serious AE was an AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect or was otherwise considered medically important. Treatment-emergent are events between first dose of study drug and up to 24 months. TEAEs include both Serious TEAEs and non-serious TEAEs.
Mean Number of New T1 (Hypointense) Lesions at Month 12 and 24	Month 12 and 24	Mean number of new T1 (Hypointense) Lesions represents a measure of accumulation of inflammatory disease burden assessed on magnetic resonance imaging (MRI) scans.
Percentage of Subjects With Combined Unique Active (CUA) Lesions at Month 12 and 24	Month 12 and 24	CUA lesion was defined as new gadolinium (Gd)-enhancing lesions on T1-weighted, or new or enlarging lesions on T2-weighted MRI scans, without double counting.
Mean Number of New Gadolinium (Gd)-Enhancing Lesions at Month 12 and 24	Month 12 and 24	New Gd-enhancing Lesions are a measure of inflammatory activity and were assessed using the Magnetic Resonance Imaging (MRI) scan.
Cumulative Number of New T1 (Hypointense) Lesions	Baseline up to Month 24	Cumulative number of new T1 (Hypointense) lesions were reported.
Median Change From Baseline in Whole Brain Volume at Month 12 and 24	Baseline, Month 12 and 24	Brain tissue volumes are inter-related and represent a measure of neurodegenerative aspects of the disease.
