Study summary

The purpose of this study is to evaluate clinical effectiveness of diacerein as add on therapy to diclofenac sodium in Indian patients of osteoarthritis (OA) knee.

Read the detailed description

Currently symptomatic relief is provided by the use of nonsteroidal anti-inflammatory drugs (NSAIDs) but they do not reverse the basic pathology of disease, rather may accelerate it, like degeneration of cartilage, inhibition of chondroitin synthesis and suppression of proteoglycans synthesis by the chondrocyte.

Research shows that IL-1β plays a fundamental role in osteoarthritis pathophysiology and cartilage destruction. Diacerein, a purified compound with anthraquinonic structure, inhibits IL-1β, retarding all pathological processes initiated in OA. Also, Diacerein has proven analgesic efficacy comparable to that of diclofenac in patients of osteoarthritis knee12. Because of these factors, the present study has been planned to evaluate the clinical effectiveness of diacerein as add on therapy to diclofenac sodium in Indian patients of symptomatic OA knee.

Exclusion criteria

Exclusion Criteria:

Those patients were excluded from the present study who:

  • were of age less than 35 years or more than 60 years
  • presented with active concomitant gastroduodenal disorders, hepatic and renal impairment within last 30 days prior to receiving the study drug
  • were diagnosed to have any inflammatory arthritis, gout or acute trauma of the knee, hip or spine; accompanying OA of the hip of sufficient severity to interfere with the functional assessment of the knee
  • had previous or ongoing treatment with oral SYSDOA (e.g., glucosamine sulphate, chondroitin sulphate, diacerein, piascledine), anti-depressants, tranquillisers, antacids or antibiotics; were having active cardiac lesion or hypertension, were pregnant females and those who were planning their pregnancy during the study

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 31, 2010, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
