Recruiting studies
- NCT05157685RecruitingPhase 3
Azithromycin for chronic pus-filled sinus inflammation
This Phase 3 trial tests whether the antibiotic azithromycin can improve chronic sinus problems where there is persistent pus and swelling. It’s for adults who have not improved despite at least two prior antibiotics.
BordeauxAges 18–70 - NCT05427695RecruitingPhase 2
Probiotic rinse to treat chronic sinus inflammation
This Phase 2 study tests whether washing your sinuses with a probiotic solution can improve chronic sinusitis symptoms and inflammation. It’s for adults with chronic sinus symptoms that have flared, especially if you’ve had sinus surgery in the past.
Chicago, IllinoisAges 18 years+ - NCT04645511Recruiting
Balloon treatment for long-term or repeat maxillary sinusitis
This study tests whether balloon sinuplasty works better or more efficiently for people with long-lasting or repeatedly returning inflammation in the maxillary sinuses (side sinuses near your cheeks). It focuses on people who did not improve with the usual nose spray (topical steroid) or who meet specific “recurrent” episode patterns.
TampereAges 18–69 - NCT07073664Enrolling by invitation
Endoscopic sinus expansion plus Stapokibart for chronic sinusitis
This trial tests if a new drug (Stapokibart) combined with a sinus surgery improves symptoms like nasal congestion, discharge, and loss of smell in people with type 2 chronic sinusitis.
Changchun, JilinAges 18–75 - NCT07107256RecruitingPhase 3
Study of TQC2731 for chronic sinusitis with nasal polyps
This trial tests an injectable drug called TQC2731 for people with chronic sinusitis and nasal polyps that haven't been controlled well enough by standard treatments like steroid sprays or surgery. The goal is to see if it helps reduce nasal congestion, improve sense of smell, and shrink polyps.
Fuyang, AnhuiAges 18–75 - NCT02975310Recruiting
In-clinic endoscopy surgery for chronic sinus polyps
This trial tests an in-clinic (not hospital) endoscopic procedure to remove nasal polyps in people with chronic sinus inflammation, after usual medicines haven’t helped. It may help reduce nasal blockage and improve sinus symptoms, while comparing safety and outcomes after the procedure.
Vancouver, British ColumbiaAges 18 years+ - NCT06960876Recruiting
Ultrasound vs. sinus massage for chronic sinusitis
This study compares two treatments for chronic sinusitis: ultrasound therapy (sound waves applied to the face) and sinus massage (gentle pressure on the face). Both are non-drug options that may help relieve your symptoms.
IslamabadAges 20–60 - NCT05882903RecruitingPhase 2
Nasal steroid cream after sinus surgery for chronic sinus trouble
This trial studies whether placing a steroid nasal cream inside your sinus area can reduce symptoms in people with chronic rhinosinusitis (CRS) even after sinus surgery. It may help lower ongoing inflammation and symptoms for those who still feel unwell despite usual medical treatments.
Sydney, New South WalesAges 18–80 - NCT07174115RecruitingPhase 2
Testing a new tablet for chronic sinusitis without nasal polyps
This trial tests an experimental tablet (HTMC0658) for people with chronic sinusitis that hasn't improved with standard nasal spray. You may join if your symptoms are moderate to severe and you've been using a stable dose of mometasone spray for at least 4 weeks.
Luoyang, HenanAges 18–75 - NCT06824649RecruitingPhase 4
Comparing biologics for chronic sinusitis with nasal polyps
This trial compares three different biologic medications (injectable drugs) to see which one works best for people with chronic sinusitis and nasal polyps. If you have moderate to severe symptoms and are considering biologic therapy, this study might help find the best option for you.
Portland, OregonAges 18 years+ - NCT06750302RecruitingPhase 1/Phase 2
Penthrox vs placebo for sinus surgery pain
This trial tests if a pain reliever called Penthrox (methoxyflurane) works better than a placebo for pain during minor sinus procedures. If you are having a simple sinus surgery or coblation procedure, you may be able to join.
Vancouver, British ColumbiaAges 19 years+ - NCT07546682Recruiting
Propel Sinus Implant Study in Japan
This study tests a steroid-releasing implant placed during sinus surgery to help prevent inflammation and improve healing in patients with chronic sinus infections. If you're having sinus surgery in Japan, this trial may track how well the implant works for you.
AsahikawaAges 18 years+ - NCT07446738Recruiting
Study of recovery and quality of life after nasal polyp surgery
This study looks at how well patients recover and their quality of life after surgery for nasal polyps caused by chronic sinusitis. It is for people in China who have just had surgery to remove nasal polyps.
ChangchunAges Any age - NCT07498374Recruiting
Drug-eluting stent for eosinophilic sinusitis with nasal polyps
This trial tests a fully dissolvable stent that releases medication inside the sinuses after surgery. It is for patients with a specific type of sinusitis (eosinophilic) and nasal polyps who either need surgery or have had surgery and show early signs of inflammation returning.
Xi'an, ShaanxiAges 18–65 - NCT04469439Recruiting
Sinus surgery in adults with cystic fibrosis
This study looks at how endoscopic sinus surgery affects people with cystic fibrosis who have ongoing sinus problems even after medical treatments. It may help doctors understand whether surgery plus ongoing care improves symptoms and quality of life.
Los Angeles, CaliforniaAges 18–99 - NCT03725956Recruiting
Sleep study before and after nasal polyp surgery
This study uses a sleep test to look at breathing and sleep patterns in people with nasal polyps who need surgery because medicine didn’t help. It may help doctors understand how nasal polyps affect sleep and how surgery changes those sleep measurements.
LilleAges 18 years+ - NCT07286201Enrolling by invitation
Nasal packing with steroid to improve sinus surgery results
This study tests a special nose dressing that slowly releases a steroid to reduce inflammation and improve healing after sinus surgery for chronic sinusitis with or without nasal polyps.
Colorado Springs, ColoradoAges 18 years+ - NCT06986629Recruiting
Light or magnetic field therapy for chronic sinusitis
This trial tests two treatments—light therapy or pulsed magnetic fields—to see if they improve quality of life for adults with chronic sinusitis. It may help if your symptoms are mild to moderate and you have allergies.
CairoAges 20–40 - NCT06129552Recruiting
Healthy nose cells study for sinusitis insight
This study is looking at healthy people to understand how certain cells in the nose work. It will compare them to people with sinus problems to learn what goes wrong in chronic sinusitis with nasal polyps.
LeuvenAges 18 years+ - NCT06191640Recruiting
Study of sinus disease in young children with cystic fibrosis
This study looks at sinus problems in young children with cystic fibrosis. One group of children starts a new medicine called a highly effective modulator (like Trikafta), and the other group does not take this medicine. The goal is to see how the medicine affects sinus health over time.

Common questions
- Are there clinical trials for chronic sinusitis?
- Yes. Clin2 currently lists 20 recruiting chronic sinusitis 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 sinusitis 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 sinusitis 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.
