Recruiting studies in California
- NCT03876054Recruiting
Tracking outcomes after Abbott neurostimulator implantation
This study follows people long-term after they get an Abbott device implanted to help with chronic pain. It aims to learn how well the therapy works in real-world care over time.
Larkspur, CaliforniaAges 18 years+ - NCT04679844Recruiting
Test bone putty for back fusion versus bone graft alternatives
This study compares a ready-to-use bone putty to standard bone graft materials (with or without your own bone) during back fusion surgery for unstable lower back problems. It looks at whether the putty works as well or better to help the bones fuse and heal.
Irvine, CaliforniaAges 18 years+ - NCT04441034RecruitingPhase 4
Compare two medicines for long-term pain in real life
This trial compares two types of medicines—anti-convulsants and anti-depressants—for people with persistent pain lasting more than 3 months. It aims to find out which option works better in everyday care and for which patients.
Redwood City, CaliforniaAges 18 years+ - NCT04278404Recruiting
Drug safety study for children already on certain medicines
This study measures how certain medicines move through the body and checks their safety in children. It may help doctors better understand dosing and side effects in kids who are already receiving these treatments, or in some kids who recently tested positive for COVID-19.
Los Angeles, CaliforniaAges birth–20 years - NCT03952299RecruitingPhase 3
Oxybutynin patch after bladder surgery for children’s urgency pain
This study tests whether an oxybutynin skin patch after bladder surgery can reduce bladder pain and urgent, frequent urination in children. It compares symptoms after surgery to see if the patch helps more than the control plan.
Sacramento, CaliforniaAges 4–8 - NCT03759028RecruitingPhase 4
Study of pain relief after elbow fracture surgery
This trial looks at how well different pain medicines work after surgery for a specific type of broken elbow bone. It may help find a safer, more comfortable pain-control plan while the fracture heals.
Los Angeles, CaliforniaAges 4–12 - NCT03796572RecruitingPhase 4
Nerve-block pain relief after a specific elbow bone fracture
This trial studies whether a pain-relief “nerve block” with medicine helps control pain after surgery for a particular type of elbow (humerus) fracture. It may help you feel more comfortable during recovery, compared with standard pain control.
Los Angeles, CaliforniaAges 4–12 - NCT03365908Enrolling by invitation
Pain Management After ACL Reconstruction Surgery
This study looks at ways to manage pain in adults who are getting surgery to repair a torn ACL (a knee ligament). It may help improve comfort and recovery after ACL reconstruction.
Sacramento, CaliforniaAges 18–45 - NCT01550575Recruiting
Study of outcomes in people treated with Boston Scientific devices
This study looks back at what happened to patients after treatment (or if they could have used) Boston Scientific medical devices. It may help improve how these devices are used and understand real-world results.

What taking part in a pain 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.

Common questions
- Are there pain clinical trials in California?
- Yes. We're currently tracking 177 recruiting pain studies with a site in California, each rewritten in plain language so you can see what it's testing and who it's for.
- How do I find out if I qualify for a pain study in California?
- Each study lists its eligibility rules — age, diagnosis, prior treatments. On every trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Do I have to live in California to take part?
- Not necessarily. These studies have a site in California, but eligibility is about your health, not your address — some people travel to take part, and a few studies reimburse travel. The study team can tell you what's required.
- Does it cost anything to join a pain trial?
- Using Clin2 is always free. Many trials cover the study treatment and related visits; some reimburse travel. The study team explains exactly what's covered before you decide.
Not the right time?
New pain studies open in California regularly. Set up a health profile and we’ll quietly watch for studies that fit you and email you when one opens.
