Recruiting studies
- NCT05068791RecruitingEarly Phase 1
Psilocybin-assisted treatment for long-term body pain
This early trial studies whether psilocybin, given in a supported setting, can reduce long-term widespread musculoskeletal pain (including fibromyalgia-like symptoms). You would be monitored closely and need someone to take you home after the medicine session.
Birmingham, AlabamaAges 25–65 - NCT05067998Recruiting
Natural medicine and vitamin IV study for overall health
This study looks at whether natural medicine, vitamin IV fluids, and supplements can help people maintain good health. There don’t appear to be specific eligibility limits listed, so many people may be able to join, but you’d still need screening by the study team.
Dover, DelawareAges 21–80 - NCT05459402RecruitingPhase 2/Phase 3
Methadone dose testing for opioid use disorder pain relief
This study compares taking methadone as one dose versus split into two doses to see which approach works better for people who have pain. It’s meant for adults already on a steady methadone program and who can follow study visits and procedures.
Baltimore, MarylandAges 18–100 - NCT05555485Recruiting
Check if ear stimulation can help chronic pain and reduce opioids
This study tests whether a device that stimulates the ear (through the skin) can reduce chronic pain and help people lower their opioid pain medicine. It may help you manage pain with less opioid use if you meet their safety and medication criteria.
Galveston, TexasAges 18–65 - NCT05580419Recruiting
Program training to improve chronic pain care
This trial tests whether a 4PCP training program for primary care clinicians improves both clinician and patient outcomes for people living with chronic non-cancer pain. If you have long-lasting pain and can take part in questionnaires and visits, your participation may help evaluate whether this program leads to better care and results.
Cleveland, OhioAges 14–80 - NCT05585229RecruitingPhase 2
Psilocybin therapy to help you taper opioid pain medicine
This Phase 2 study tests a structured, therapist-led treatment using standardized natural psilocybin to help people reduce or stop long-term opioid use for chronic (non-cancer) pain. It’s mainly for those who have tried tapering before but couldn’t, and who are motivated to try again.
Kelowna, British ColumbiaAges 19–75 - NCT05596591Recruiting
Shockwave treatment for knee arthritis pain with MRI-confirmed lesions
This trial tests whether focused shockwave therapy (a non-surgical treatment) can reduce knee arthritis pain. It specifically targets people whose MRI shows a small bone problem in one area of the knee.
Cedar Knolls, New JerseyAges 30–80 - NCT05661903RecruitingPhase 2
Spinal cord stimulator study for nerve pain and brain effects
This Phase 2 study looks at how spinal cord (or nerve-root) stimulation affects pain signals in the brain and body. You may qualify if you already have a stimulator set to a comfort mode that avoids “tingling” sensations.
Boston, MassachusettsAges 18–80 - NCT05697159Recruiting
7-tesla brain MRI to study how filgotinib eases RA pain
This trial uses a very high-strength brain MRI to understand how the RA medicine filgotinib may reduce pain. If you have active rheumatoid arthritis and can safely complete the scan, the study may help researchers better target pain relief in RA.
GlasgowAges 18–74 - NCT05761015RecruitingPhase 4
Test of an NSAID to help osteoarthritis pain when walking
This trial studies whether taking an anti-inflammatory pain medicine (an NSAID) can reduce hip or knee osteoarthritis pain during walking. It may help people who have had walking pain for at least 3 months and don’t already take NSAIDs.
Clermont-FerrandAges 50–70 - NCT05788016Recruiting
Help planning an opioid taper before knee or hip surgery
This study looks at a plan to safely reduce (taper) opioid pain medicines before total knee or hip replacement surgery. It may help people who are already taking opioids and are preparing for surgery in the next 1 to 2 months.
Birmingham, AlabamaAges 18 years+ - NCT05885061Recruiting
Spinal cord stimulation study for adults with chronic pain
This study looks at how spinal cord stimulation affects chronic pain in adults who already have the device implanted. It may help researchers understand who benefits most and how stable pain and treatments need to be to measure results.
AarhusAges 18–99 - NCT05905419Recruiting
Brain scan study of opioid effects in women with pain
This study uses brain imaging (MRI) to understand how opioid medications may affect the brain in women. People with chronic pain who take opioids (or do not) and healthy women without chronic pain may be invited to participate.
Durham, North CarolinaAges 18 years+ - NCT05981573Recruiting
Measuring methadone doses for chronic pain
This trial is for people with chronic pain who take daily methadone. It aims to measure how much methadone is in your body to help doctors find the right dose.
Lemon Grove, CaliforniaAges 18–70 - NCT06207851Recruiting
Micro-embolization for chronic elbow or wrist pain
This trial tests a minimally invasive procedure called TAME that uses tiny beads to block small blood vessels in the elbow or wrist, which may reduce chronic pain. It's for people whose pain hasn't improved with other treatments.
Seoul, Kwang Jin GuAges 19–80 - NCT06213233RecruitingPhase 2
CBD oil for veterans with chronic pain
This study tests whether CBD oil can help veterans manage chronic pain. You would take a daily dose of CBD and report your symptoms using a smartphone app.
Ann Arbor, MichiganAges 18 years+ - NCT06239649Recruiting
Nerve block before knee replacement for faster recovery
This trial tests whether a numbing injection (nerve block) around the knee before surgery can help you recover faster and feel less pain after a total knee replacement. It is for people with knee osteoarthritis who are ready for their first knee replacement surgery.
Denizli, PamukkaleAges 40–85 - NCT06283862Recruiting
Virtual cannabis coaching for veterans with chronic pain
This study tests a virtual program to help veterans with chronic pain who are using (or planning to use) CBD or cannabis. You'll join educational sessions and track your symptoms and cannabis use on your smartphone.
Ann Arbor, MichiganAges 18 years+ - NCT06297200Recruiting
Ultrasound treatment for complex back pain patients
This study tests a new, non-invasive ultrasound treatment for people with long-term back pain who also have opioid use disorder and anxiety. It aims to see if this gentle brain stimulation can reduce pain and improve quality of life.
Roanoke, VirginiaAges 18–65 - NCT06350409Recruiting
Opioid use after surgery in teens
This study looks at how teens aged 12–17 use opioids after a scheduled surgery. It aims to understand outcomes and help improve pain management.
Aurora, ColoradoAges 12–17 - NCT06353789Recruiting
Teen Period Pain and Future Health
This study at the University of Oxford is looking at whether painful periods in teenagers can lead to long-term pain. You will be asked about your period pain and may have an MRI scan of your brain (safe, no radiation). The goal is to find ways to prevent chronic pain later in life.
Oxford, OxfordshireAges 11–20 - NCT06374537Recruiting
Exercise program for weak kidney patients
This study tests whether a targeted exercise program can help people who are very weak due to kidney disease. If you are on dialysis, have advanced kidney disease, or have had a kidney transplant, this program may improve your strength and daily function.
Chicago, IllinoisAges 18 years+ - NCT06406244Recruiting
TEAS for chronic pain after liver surgery
This trial tests whether a gentle, needle-free electrical stimulation on certain points on the body (called TEAS) can help reduce chronic pain after liver surgery and improve long-term survival. It may be a good option if you are scheduled for a liver removal and want to explore non-drug pain relief.
ChengduAges 18–80 - NCT06424743Recruiting
Strength training volume for women with fibromyalgia

- Are there clinical trials for chronic pain?
- Yes. Clin2 currently lists 828 recruiting chronic pain studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a chronic pain trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a chronic pain trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
