Study on Metformin for Pain Relief in Patients with Hand Osteoarthritis

This clinical trial is investigating whether metformin can help reduce pain in people with hand osteoarthritis. While metformin is traditionally used to treat type 2 diabetes, researchers are exploring whether it might also have benefits for joint pain due to its potential anti-inflammatory effects.

Main inclusion criteria:

• Participants must be at least 18 years old
• Confirmed diagnosis of hand osteoarthritis by a doctor
• Hand pain, aching, or stiffness on most days in the past 4 weeks
• Specific physical features such as hard tissue enlargement in at least 2 of 10 selected finger joints, or joint deformity
• Average finger pain score of 4 or higher on a scale from 0 to 10 over the past 30 days
• Participants must not have taken metformin before

Main exclusion criteria:

• People not experiencing finger joint pain
• Individuals without a confirmed osteoarthritis diagnosis
• Those outside the specified age range
• Vulnerable populations requiring special protection or care

Study focus and design:

The trial lasts 16 weeks and compares metformin to a placebo, which is an inactive substance that looks like the medication but contains no active ingredients. Participants are randomly assigned to receive either metformin (500 mg film-coated tablets taken orally) or the placebo. The main goal is to measure changes in finger joint pain using a visual analogue scale after the 16-week treatment period. At the end of the study, participants attend a visit in week 17 to evaluate how their pain levels have changed from the beginning.

Investigational drug:

Metformin is the medication being tested in this trial. It works by decreasing glucose production in the liver and improving insulin sensitivity. Researchers believe these properties may also have anti-inflammatory effects that could benefit joint health and reduce pain in people with hand osteoarthritis.

Summary

Currently, there is one active clinical trial for nodal osteoarthritis, taking place in Denmark. This trial represents an interesting approach to treating hand pain, as it tests metformin, a medication not traditionally used for joint conditions. The study focuses specifically on measuring pain relief in the finger joints over a 16-week period. This research may provide valuable insights into whether existing medications for other conditions could offer new treatment options for people living with hand osteoarthritis. Participants interested in this trial should meet specific criteria regarding their diagnosis, pain levels, and medical history.
