Brief summary: This is a multi-centre, double blind, randomised, placebo controlled, parallel group, phase 4 pilot study investigating colecalciferol (vitamin D3) as an add-on treatment to subcutaneously administered interferon-beta-1b in relapsing-remitting multiple sclerosis patients.


Eligibility criteria: Inclusion Criteria:

* age 18 to 55 years
* remitting-relapsing multiple sclerosis according to McDonald criteria who fulfill the reimbursement criteria for interferon-beta and have used interferon-beta-1b for at least one month
* EDSS (expanded disability statsu scale) ≤ 5
* no neutralising antibodies to INFB as measured by indirect MxA test
* prepared and considered to follow the protocol
* using appropriate contraceptive methods (women of childbearing potential)
* has given informed consent

Exclusion Criteria:

* serum calcium \>2.6 mmol/L
* serum 25(OH)D2 (kalsidiol) \> 85 nmol/L
* presence of primary hyperparathyroidism (serum intact PTH, parathyroid hormone)\>65 ng/L)
* pregnancy or unwillingness to use contraception
* alcohol or drug abuse
* use of glucocorticoid treatment other than intravenous methylprednisolone for treatment of relapses
* current use of other immunomodulatory therapy than interferon-beta-1b
* known allergy to cholecalciferol or arachis oil (peanuts)
* therapy with digitalis, calcitonin or active vitamin D3 analogues during the previous 12 months or multivitamins containing vitamin D during previous two weeks preceding study entry
* any condition predisposing to hypercalcaemia (such as any type of cancer)
* sarcoidosis
* nephrolithiasis or renal insufficiency, serum creatinine above 1.5 times the normal upper reference limit
* significant hypertension (Blood Pressure \<180/110 mmHg)
* hyperthyroidism, or hypothyroidism in the year before the study began
* a history of nephrolithiasis during the previous five years
* cardiac insufficiency or significant cardiac dysrhythmia
* unstable or advanced ischaemic heart disease
* has suffered a major depression
