NCT01176344

Brief Summary

Observational evidence suggests that vitamin D deficiency may have a role in the causes of osteoarthritis (OA) and there are biologically plausible mechanisms to explain this. There is, however, no evidence which shows that intervening with vitamin D supplementation can slow the progression of OA. This study is to determine if vitamin D supplementation can reduce knee pain and slow knee cartilage loss in OA patients comparing with a placebo. Use of MRI will provide sensitive measures of knee OA changes.

    Over 2 years

Secondary Outcomes (7)

  • Progression of knee cartilage defects

    Over 2 years (Cartilahe defects will be measured at baseline and 2 years later)

  • Change in bone marrow lesions

    Over 2 years

  • Change in knee pain

    Over 2 years

  • Change in physical function

    Over 2 years

  • Change in joint effusion

Eligibility Criteria

Age50 Years - 79 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age 50-79 years old;
  • Men and women with symptomatic knee osteoarthritis (OA) with a pain visual analogue scale (VAS) of at least 20 mm in most days of the last month;
  • Have an American College of Rheumatology (ACR) functional class rating of I, II and III;
  • Have relatively good health (0-2 according to the investigator's global assessment of disease status on a 5-point Likert scale, range 0 \[very well\] to 4 \[very poor\]);
  • Have serum vitamin D level of \>12.5 nmol/L and \<60 nmol/L;
  • Are able to read, speak and understand English, capable of understanding the study requirements and willing to co-operate with the study instructions;
  • Are able and willing to give informed consent;
  • Are willing and able to give blood samples;
  • Are willing and able to have knee MRIs performed

You may not qualify if:

  • Have Grade 3 radiographic changes in their knee which is to be investigated;
  • Have severe knee pain (more than 80 mm on a 100-mm visual analogue scale,VAS) in most days of the last month;
  • Have any contra-indications for having MRIs scans performed;
  • Have had significant trauma to the knees including arthroscopy or significant injury to ligaments or menisci of the knee within 1 year preceding the screening visit;
  • Have ever had knee joint replacement;
  • Have anticipated need for knee or hip surgery in the next 2 years;
  • Have any stomach or intestinal condition possibly affecting oral drug absorption;
  • Have any clinically significant condition(s) such as (but not limited to) rheumatoid arthritis, psoriatic arthritis, lupus, active cancer, cardiac or renal function impairment or hypersensitivity to vitamin D that in the opinion of the investigator may compromise their safety or compliance, interfere with evaluation or preclude completion of the study.
