Enzalutamide plus relacorilant versus placebo for high-risk prostate cancer
This study tests whether adding relacorilant to enzalutamide (a hormone-blocking treatment) helps control high-risk localized prostate cancer better than enzalutamide plus a dummy pill. It may help prevent the cancer from growing or spreading by targeting a hormone pathway in addition to standard treatment.
Chicago, IllinoisAges 18 years+ - NCT05737121RecruitingPhase 2
Study drug for bladder pain compared with lidocaine, heparin, or placebo
This Phase 2 trial tests VNX001 to see if it helps people with interstitial cystitis/bladder pain syndrome (IC/BPS) compared with its separate ingredients (lidocaine and heparin) or a placebo (inactive treatment). You may be eligible if you have had IC/BPS for months and recently had a moderate-to-severe bladder pain flare.
Escondido, CaliforniaAges 18 years+ - NCT05744687RecruitingPhase 2/Phase 3
Letrozole plus SPH4336 versus letrozole alone for breast cancer
This study tests whether adding SPH4336 to letrozole works better than letrozole plus a placebo for treating hormone-receptor–positive, HER2-negative breast cancer in people starting first-line treatment. It may help slow cancer growth more effectively if the added drug is beneficial.
Fuzhou, FujianAges 18–75 - NCT05761860RecruitingEarly Phase 1
Oxytocin to lower opioid misuse risk and pain in older adults
This early-phase study tests whether oxytocin (a hormone-like medication) can reduce how “appealing” opioids feel and also reduce pain. It’s aimed at older adults who have used opioids before but are not currently dealing with chronic pain most days.
Gainesville, FloridaAges 45–85 - NCT05772871RecruitingPhase 4
Prednisone plus herbal granules for children with nephrotic syndrome
This trial tests whether adding Huaiqihuang granules to prednisone can improve outcomes for children with primary, hormone-sensitive nephrotic syndrome. It also closely monitors safety to see if the combination causes fewer or more side effects than usual care.
Hefei, AnhuiAges 1.5 years–18 years - NCT05795478Recruiting
Oxycodone plus pregabalin for long-term pain after spinal surgery
This trial studies whether taking oxycodone together with pregabalin (both pain medicines) can reduce chronic pain that can linger after spinal surgery. If you qualify, you may be asked to rate your pain and complete questionnaires during recovery.
BeijingAges 18 years+ - NCT05821478RecruitingPhase 3
Antibiotics plan for hidradenitis stage 2 flares
This Phase 3 study tests whether an adapted antibiotic treatment works better than the standard approach to control hidradenitis suppurativa (HS) symptoms and flares. It may help people with stage 2 HS reduce active inflammation and flare-ups.
MarseilleAges 18–59 - NCT05832567Recruiting
Study of hidden and open placebo effects in stroke recovery
This study looks at how “open” (told) and “hidden” (not told) placebo effects may change arm recovery after a long-term stroke. You would do recovery-related assessments and likely receive brain-stimulation or related procedures to test these effects.
Cambridge, MassachusettsAges 18 years+ - NCT05842512RecruitingPhase 2
Drug ADI-PEG 20 for NASH in people with mild cirrhosis
This trial tests ADI-PEG 20 against a placebo (inactive pill) to see if it improves liver disease in people with NASH and compensated cirrhosis. It may help by targeting liver fat and inflammation seen on scans and biopsy.
Chiayi City, TaiwanAges 18–80 - NCT05851508RecruitingPhase 3
Steroid ear injections for vertigo in one-ear Ménière’s
This Phase 3 study compares injections of steroid medicine into the ear versus a dummy (placebo) injection to see if it reduces vertigo attacks in people with Ménière’s disease. It may help by improving balance symptoms and reducing how often attacks happen.
Leiden, South HollandAges 18–100 - NCT05854667RecruitingPhase 2
High-dose lisdexamfetamine with rewards for meth use changes
This Phase 2 study tests high-dose lisdexamfetamine (a prescription stimulant) to help people reduce or stop methamphetamine use. It also uses “contingency management” (rewards tied to meeting goals) to encourage treatment participation and lower use.
Vancouver, British ColumbiaAges 18–55 - NCT05855746RecruitingPhase 3
Colchicine vs placebo for acute myocarditis
This trial tests whether colchicine (a medicine that reduces inflammation) improves outcomes in people with acute myocarditis soon after symptoms start. Half of participants get colchicine and half get a placebo to see which works better.
BronAges 18–65 - NCT05862337RecruitingPhase 3
New immune plus anti-cancer pills to prevent liver cancer returning
This Phase 3 trial studies anlotinib capsules plus penpulimab (an immune therapy) to help prevent hepatocellular carcinoma from coming back after it has been fully removed or fully destroyed. It may help high-risk patients lower the chance of recurrence and improve survival.
Bengbu, AnhuiAges 18–75 - NCT05865470RecruitingPhase 1
How age affects smoked and oral THC effects
This early-stage study compares how people in different age groups respond to THC taken by smoking versus by mouth. It aims to understand age-related differences in effects and safety, which could help guide safer use in the future.
Los Angeles, CaliforniaAges 18–65 - NCT05874401RecruitingPhase 4
Trilaciclib added to topotecan for advanced small cell lung cancer
This study tests whether adding trilaciclib (a medicine given with chemotherapy) can improve outcomes for people with extensive-stage small cell lung cancer who are being treated with topotecan. It compares trilaciclib versus a placebo (inactive pill) while you receive topotecan.
SevilleAges 18 years+ - NCT05894239RecruitingPhase 3
Tested targeted drug for HER2-positive breast cancer with PIK3CA changes
This Phase 3 study tests inavolisib plus Phesgo versus placebo plus Phesgo in people whose breast cancer has both HER2-positive and PIK3CA-mutated tumor markers. The goal is to see if adding inavolisib improves how well the treatment controls the cancer and how safe it is.
Gilbert, ArizonaAges 18 years+ - NCT05913388RecruitingPhase 2
Testing a new drug plus pembrolizumab versus pembrolizumab alone
This Phase 2 trial studies whether adding GB1211 to pembrolizumab works better than pembrolizumab with a placebo in people with metastatic melanoma or metastatic head and neck squamous cell cancer. It may help shrink tumors and improve outcomes, but it also carries risks from immune-based treatment.
Portland, OregonAges 18 years+ - NCT05952167Recruiting
Neck traction vs placebo traction for pinched nerve symptoms
This study tests whether using neck traction (gentle pulling) helps people with cervical radiculopathy (a pinched nerve in the neck). It compares real traction to a placebo (sham) traction to see if symptoms and neck function improve.
La Roche-sur-YonAges 18 years+ - NCT05986292RecruitingPhase 2
Study of new treatments for chronic pain
This study tests new treatments for chronic pain that lasts at least 3 months. Participants must stop their regular pain medicines and use only a rescue painkiller if needed. The goal is to find better ways to manage long-term pain.

Nashville, TennesseeAges 18–65 - NCT05988632RecruitingPhase 1/Phase 2
Insulin nasal spray for alcohol use disorder
This trial tests whether a nasal spray with insulin can help people with alcohol use disorder. It may affect how the brain responds to alcohol and reduce drinking.
Providence, Rhode IslandAges 21 years+ - NCT06008860RecruitingPhase 4

Common questions
- Are there clinical trials for placebo?
- Yes. Clin2 currently lists 5,225 recruiting placebo 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 placebo 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 placebo 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.
