* Have progressive primary multiple sclerosis according to McDonald's diagnostic criteria modified in 2010.
* Age between 18 and 65 years old.
* Neurological impairment measured with the Expanded Disability Status Scale (EDSS) scale between 2 and 7 (both included, without disability or only clinical symptoms up to ambulatory capacity with bilateral support).
* Not having received any immunomodulatory, except for ocrelizumab in stable doses for at least 9 months before inclusion in this study, or immunosuppressive treatment (including cytostatic agents) during the 3 months prior to participation in the trial.
* If there is a possibility of pregnancy (in women of childbearing age (15 to 44 years)) or paternity, accept the use of a highly effective method of birth control recommended by the Clinical Trial Facilitation Group (CTFG) during the treatment phase of the trial..

* Ability to give informed consent and comply with the visits scheduled in the study.

Exclusion Criteria:

* Alternative diagnosis that explains both the neurological disability and the findings in nuclear magnetic resonance.
* Clinically significant medical problems that, in the opinion of the investigators, may cause tissue damage in the central nervous system or limit its repair, or that may expose the patient to unjustified risks or damages, or cause the patient not to complete the study.
* Clinical history of hypersensitivity reactions to melatonin.
* Pregnancy or lactation, or planning to become pregnant or patients of childbearing age not subject to birth control methods (recommended by the Clinical Trial Facilitation Group (CTFG)).
* Abnormal results in basal blood tests, defined as:
* Serum levels of alanine transaminase or aspartate transaminase greater than 1.5 times the upper limit of normal values.
* Total leukocyte count less than 3,000 / mm3.
* Platelet count less than 85,000 / mm3.
* Serum creatinine level greater than 2.0 mg / dL or glomerular filtration rate less than 30.
* Neurological deterioration measured with the Expanded Disability Status Scale scale of less than 2 or greater than 7.
