    Clinical Trials

    Please note our product candidates are not yet available or approved for use.

    MedDay is developing products in a tightly regulated environment of clinical studies that are reviewed and approved by the national respective authorities to establish a maximum safety level for patients. Currently, therefore, access to our trials is limited to patients meeting the eligibility criteria of our clinical trials.

    MS-SPI and MS-ON Trial Results

    MedDay reported full study results from the Phase IIb/III MS-SPI and MS-ON trials, including the MS-SPI extension data, at the American Academy of Neurology Annual Meeting (AAN) in April 2016.

    MS-SPI and MS-ON studies tested the efficacy of lead product candidate MD1003, a patented pharmaceutical-grade biotin administered at a dose of 300 mg per day in the treatment of multiple sclerosis (MS) and particularly of the most difficult to treat “not-active progressive MS,” for which there is no approved drug.

    Overall these data show the best effect size ever observed to date and confirm the good safety profile of MD1003.
