Recruiting studies in California
- NCT06884865RecruitingPhase 2
Study of an experimental knee injection for osteoarthritis pain
This study tests a new investigational medicine injected into the knee to see if it is safe and tolerable for people with painful knee osteoarthritis. It may help reduce pain and improve knee function.

A study of an experimental pill for weight loss and knee arthritis
This trial tests an investigational medication (orforglipron) to see if it helps people with knee arthritis lose weight. You may qualify if you have overweight or obesity and have tried dieting before without lasting success.
Huntington Beach, CaliforniaAges 18 years+ - NCT05495334Recruiting
Add knee osteoarthritis outcomes to a patient registry
This study tests a new way to collect how people with knee osteoarthritis feel and function after usual care (like injections, nerve-blocking procedures, or knee replacement). It may help improve future treatment decisions by using your regular follow-up reports in an app or online.
Irvine, CaliforniaAges Any age - NCT06574191Recruiting
Knee osteoarthritis study: pain and health outcomes
This study looks at how knee pain from osteoarthritis affects your daily life and health. You'll use a topical anti-inflammatory gel and answer questions by text or email for two months.
Sacramento, CaliforniaAges 50 years+ - NCT06608134RecruitingEarly Phase 1
Umbilical cord injection for knee osteoarthritis pain
This trial tests whether a special injection made from umbilical cord tissue can safely help with knee osteoarthritis pain. If you have moderate knee arthritis and haven't had recent injections or surgery, you may be able to join.

Travis AFB, CaliforniaAges 45–75 - NCT07481630RecruitingPhase 3
Testing a new medicine for weight loss and knee pain
This study tests if a new medicine called NNC0487-0111 can help people with extra weight and knee osteoarthritis lose weight and reduce knee pain. If you have knee pain most days and are willing to stop pain relievers for short periods, you may be able to join.
Walnut Creek, CaliforniaAges 18 years+ - NCT07226258RecruitingPhase 3
Testing SL1002 for knee pain caused by osteoarthritis
This trial tests a study drug called SL1002 to see if it reduces knee pain from osteoarthritis. It may be an option for people with chronic knee pain who haven't found enough relief from current treatments.
Roseville, CaliforniaAges 40 years+ - NCT06917404RecruitingPhase 3
Knee osteoarthritis pain study: comparing a new injection to placebo
This phase 3 study tests whether a medicine called pentosan polysulfate sodium (PPS), given as a shot under the skin, reduces pain in people with knee osteoarthritis. It compares PPS to a placebo (a shot with no active medicine) to see if it is safe and effective.
Oceanside, CaliforniaAges 18 years+ - NCT07219771RecruitingPhase 3
Testing MOTYS injection for knee osteoarthritis pain
This trial tests an injection called PTP-001 (MOTYS) for people with mild to moderate knee osteoarthritis. It aims to see if the injection can reduce knee pain and improve function.
West Hills, CaliforniaAges 40–80 - NCT07308834RecruitingPhase 1/Phase 2
Injection for knee osteoarthritis pain
This study tests an injection called CX-011 for people with knee osteoarthritis who still have moderate to severe pain despite trying other treatments. The goal is to see if the injection can reduce pain and improve knee function.
Los Angeles, CaliforniaAges 40–75 - NCT07580222Recruiting
Using Mobile Technology to Track Knee Arthritis Health
This study uses smartphone or tablet technology to measure how your knee osteoarthritis (wear-and-tear arthritis) changes over time. You'll be helping researchers understand how well a previous arthritis treatment works by tracking your knee health at home.
Palo Alto, CaliforniaAges 30 years+ - NCT04472702Recruiting
Ultrasound vs X-ray guidance for knee pain ablation
This trial compares two ways (ultrasound or X-ray guidance) to place a treatment for painful knee arthritis. It aims to see whether one guidance method works as well as the other for reducing knee pain.
Sacramento, CaliforniaAges 35–99 - NCT07509307RecruitingPhase 3
Study of a new medicine for weight loss and knee pain in osteoarthritis
This trial tests if a new medicine, NNC0487-0111, can help people with excess weight and knee osteoarthritis lose weight and reduce knee pain. It is for people who have had knee pain for at least three months and who can stop taking pain relievers for short periods before study visits.
Escondido, CaliforniaAges 18 years+ - NCT06906939RecruitingEarly Phase 1
Brain stimulation and tai chi for knee arthritis and depression

What taking part in a osteoarthritis (oa) of the knee study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
