Study to Assess the Safety and Tolerability of MBF-015 in Healthy Young Volunteers

Study Overview
=================
Brief Summary
-----------------
This is a single center, randomised, double blind, placebo controlled clinical study to assess the safety and tolerability of MBF-015 in healthy volunteers.This clinical phase I trial is divided in two stages and involves, first, a single ascending dose (SAD) study in healthy young male volunteers and then a multiple ascending dose (MAD) study in healthy young men and woman. MBF-118 is developed for the treatment of multiple sclerosis.

Detailed Description
-----------------
This clinical phase I trial is divided in two stages. The first stage will be a dose escalation study without therapeutic benefit, in which MBF-015 will be administered as single oral ascending dose to healthy young male volunteers. Up to four different rising doses will be tested (4 mg, 8 mg, 16 mg, 32 mg, 64 mg) in groups/cohorts of 8 participants. Thus, five groups/cohorts will participate. For each dose level/group, the participants will be randomized to active or placebo with 2 participants being randomly assigned to placebo and 6 to the active drug. First, one volunteer will receive active drug and another one will receive placebo (subgroup 1); after at least 72h of safety and tolerability assessment a second subgroup of 3 volunteers will receive 2 active drug and 1 placebo; after at least another 72h of safety and tolerability parameters assessment, a third subgroup of 3 volunteers will receive the active drug. After evaluation of safety parameters of corresponding dose level, the process will replicate one week afterwards in the following dosages. The second stage will be a dose escalation study without therapeutic benefit, in which MBF-015 will be administered as single oral daily dose, during 5 days to young male and female healthy volunteers. Up to four different rising dose levels will be tested (8 mg, 16 mg, 32 mg, and 64 mg) in cohorts of 8 subjects that are randomised to active treatment and placebo (6:2) and divided into three subsequent treatment blocks, as described above in the first stage. The pharmacokinetics profile of MBF-015 will be also assessed at each dose level tested of the Single ascending dose study and the multiple ascending dose study. The 64 mg SAD part will also be used to measure the product concentration in cerebrospinal fluid (CSF).

Eligibility Criteria
-----------------
Inclusion Criteria: To be included in the single dose study, subjects should meet all the following criteria at the screening visit: Healthy male subjects, 18-45 years (inclusive) of age at the time of enrolment. Body weight within normal range (Quetelet's index between 19 and 27) expressed as weight (kg) / height (m)2. Normal clinical records and physical examination. Laboratory tests (haematology and biochemistry) within the range of normal values, according to the Biochemistry laboratory reference values of the 'Hospital de la Santa Creu i Sant Pau'. Variations may be admitted according to the clinical criteria of the CIM-Sant Pau. Clinically acceptable temperature, blood pressure and pulse rate in supine and standing position (SBP between 100-140 mm Hg/ Diastolic Blood Pressure (DBP) between 50-90 mm Hg / HR between 50-100 bpm). Blood pressure and pulse will be measured after a minimum of 3 minutes of resting. Males should agree to abstain from sexual intercourse with a female partner or agree to use a condom with spermicide, in addition to having their female partner using some contraceptive measures as oral contraceptive drugs, intrauterine hormonal contraception, or cervical caps until 28 days post-administration. To be able to understand the nature of the study and comply with all their requirements. Free acceptance to participate in the study should be stated in an informed consent document signed by the volunteer which must be approved by the Clinical Research Ethic Committee (CREC). For the multiple dose study in healthy male and female volunteers, subjects meeting all the following inclusion criteria at screening visit: Healthy male and female subjects, 18-45 years (inclusive) of age at the time of enrolment. Body weight within normal range (Quetelet's index between 19 and 27) expressed as weight (kg) / height (m2). Normal clinical records and physical examination at screening and baseline. Laboratory tests (haematology, biochemistry and urinalysis) within the range of normal values, according to the laboratory reference values of the 'Hospital de la Santa Creu i Sant Pau'. Variations may be admitted according to the clinical criteria of the CIM-Sant Pau. Clinically acceptable temperature, blood pressure and pulse rate in supine and standing position (SBP between 100-140 mm Hg/ DBP between 50-90 mm Hg / HR between 50-100 bpm). Blood pressure and pulse will be measured after a minimum of 3 minutes of resting. Males should agree to abstain from sexual intercourse with a female partner or agree to use a condom with spermicide, in addition to having their female partner using some contraceptive measures as oral contraceptive drugs, intrauterine hormonal contraception, or cervical caps until 28 days post-administration. To be able to understand the nature of the study and comply with all their requirements. Free acceptance to participate in the study by obtains signed informed consent form approved by the CREC. Females must be of non childbearing potential (i.e. surgically sterile) or have to use contraceptive measures ( non-hormonal) such as condom, diaphragm or cervical / vault caps with spermicide until 28 days post administration Exclusion Criteria: For the single dose study and multiple dose study meeting any of the following criteria at screening visit will be excluded from entry into the study: History of alcohol dependence or drug abuse in the last 5 years or daily consumption of alcohol > 40 gr/day for men.
