Hand Osteoarthritis clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

NCT ID: NCT03703934 Suspended - Clinical trials for Arthritis, Psoriatic

Central Pain Mechanisms in Patients With Hand-Osteoarthritis, Psoriatic Arthritis and Healthy Controls

Start date: October 20, 2018
Phase:
Study type: Observational

In this trial different parts of the pain signalling system involved in two rheumatic diseases - painful hand osteoarthritis and psoriatic arthritis, is examined. These measurements will be compared to those of healthy volunteers The hypothesis is that patients with hand osteoarthritis and psoriatic arthritis react differently to painful and non-painful stimuli compared with the healthy volunteers. The aim is to recruit 66 patients with painful hand-osteoarthritis, 66 patients with painful psoriatic arthritis and 66 healthy subjects not currently suffering from any pain conditions. After completing an informed consent form subjects will participate in a single clinical visit. The pain signalling system is examined using pressure algometry and cuff algometry. A pressure algometer is a pistol shaped device that elicits pressure through a rod and a cuff algometer is akin to a blood pressure cuff. Different thresholds will be measured, such as when the sensation of pressure becomes painful and when the painful pressure becomes unbearable. Participants will also get hand strength tested, have their joints examined and answer questionnaires regarding daily function and quality of life. Furthermore participants will get blood drawn which is analysed for the presence of markers of inflammation and joint degeneration.
