Test study drugs to clear rickettsia infections
This study tests antibiotics to help your body clear rickettsia-related illnesses like murine typhus or scrub typhus. It may help reduce symptoms and shorten how long you feel sick, based on how well the infection clears.

Testing antibiotics after jaw fracture surgery
This trial studies whether giving (or how giving) antibiotics affects outcomes after surgery for a broken lower jaw (mandible). It may help reduce infection risk and antibiotic-related side effects if the right approach is chosen for the right patients.
Blackburn, LancashireAges 18 years+ - NCT05966961Recruiting
Compare two stitches to close surgical wounds

Community outreach to improve vaccine acceptance in prisons
This study tests community engagement approaches to help people in prison feel more comfortable accepting vaccines. It will focus on people in regular housing areas, and it may help increase vaccine willingness through trusted local outreach.
Schwenksville, PennsylvaniaAges 18 years+ - NCT05928169Recruiting
Tracking how inflammatory skin conditions change over time
This study looks at what affects the “path” (trajectory) of long-lasting inflammatory skin conditions. It may help researchers understand why symptoms change and how treatments or factors influence those changes.
KielAges birth–80 years - NCT05914649Recruiting
Testing long COVID and POTS brain fog symptoms
This study tests how different long-COVID and POTS-related symptoms—especially “brain fog”—show up and improve. It may help researchers better measure symptoms so future treatments can be targeted more effectively.
Calgary, AlbertaAges 18–60 - NCT05912413Recruiting
Predicting how people recover from sepsis in the ICU
This pilot study looks at whether doctors can sort ICU patients with sepsis into recovery “types” and predict how well they will recover. It may help future care plans for people after sepsis by identifying who needs what kinds of support.
Birmingham, AlabamaAges 18–80 - NCT05926505RecruitingPhase 2/Phase 3
Anakinra for lingering symptoms after COVID-19
This Phase 2/3 trial studies whether anakinra can improve ongoing (post-acute) COVID-19 symptoms lasting for more than two months. It mainly looks for better safety and symptom improvement in people with specific inflammation and lung-related findings.
JenaAges 18 years+ - NCT05917210Recruiting
Peer support for TB and HIV treatment in Uganda
This trial tests a peer-led education and counseling program to help people with TB and HIV stick with their treatment. It may help improve understanding, motivation, and day-to-day adherence to medications.
KampalaAges 18 years+ - NCT05916638Recruiting
Testing a breathing pattern in people with sarcoidosis and TB
This trial looks at a specific “MoMa signature” related to breathing or lung signals in adults who have been diagnosed with both sarcoidosis and tuberculosis. It may help researchers understand how these conditions affect the body and improve how patients are monitored.
ParisAges 18 years+ - NCT05941052Recruiting
Testing new at-home TB checks in the clinic
This study tests new tools that can check for tuberculosis (TB) more quickly at or near where care happens. It includes people with cough or TB risk factors, and also the health workers who perform TB testing, to see how well the tests work and how easy they are to use.
AbujaAges 12 years+ - NCT05913180RecruitingPhase 2
Vitamin C to prevent urine infections after gynecologic surgery
This Phase 2 study tests whether taking vitamin C can lower the chance of getting a urinary tract infection (UTI) after planned gynecologic surgery. It may help people who want to reduce post-surgery infection risk.
MoscowAges 18–80 - NCT05915663Recruiting
Choosing where to place a stomach tube
This study looks at whether different placement locations for a stomach (gastric) tube can lower the risk of pneumonia in people on a breathing machine. It’s aimed at patients expected to need ventilation for more than 48 hours.
AngersAges 18 years+ - NCT05934305Recruiting
Help for shame and stigma in HIV and substance use
This study tests whether a program can reduce shame and stigma for people living with HIV who also have a substance use disorder. It may help you feel less judged and cope better, while supporting HIV care.
Miami, FloridaAges 18 years+ - NCT05934149Recruiting
Lupus health registry that stores samples for future research
This study keeps a long-term record of people with lupus (systemic lupus erythematosus) and collects samples so researchers can study the disease better. You may be able to join if you meet lupus diagnosis criteria, are not pregnant, and can follow the study visits and consent process.
Birmingham, AlabamaAges 18–110 - NCT05928767Recruiting
Using frailty scores to predict death in ICU sepsis
This trial checks whether a “frailty” rating (how physically/mentally vulnerable someone is) can predict the risk of death in ICU patients with sepsis shock. It may help doctors identify higher-risk patients earlier and tailor care.
BéthuneAges 18–65 - NCT05926804Recruiting
Screening and treatment for Helicobacter pylori in teens
This trial checks teenagers for a long-lasting H. pylori stomach infection and then treats those who need it. It may help prevent ongoing stomach problems from the infection and compare outcomes between treated and non-treated groups.
CoyhaiqueAges 14–18 - NCT04292054RecruitingPhase 3
Antibiotics to prevent infection during burn skin graft surgery
This Phase 3 study tests whether giving preventive antibiotics lowers infection risk when you need surgery to remove burned skin and place a skin graft. It may help patients heal with fewer serious infections, but it also depends on your antibiotic allergy and current health status.
ParisAges 18–99 - NCT05896839RecruitingPhase 1/Phase 2
Immunotherapy with prednisone and sirolimus for transplant skin cancer
This early-phase study tests whether adding immunotherapy (nivolumab and ipilimumab) to prednisone and sirolimus can control advanced skin cancers in people with kidney transplants. It aims to see how well the treatment works and how safe it is for transplant recipients.
La Jolla, CaliforniaAges 18 years+ - NCT05907759RecruitingPhase 2
Daratumumab for HIV-related lymphomas and Castleman disease
This trial tests a drug called daratumumab for people with certain HIV-related blood cancers (primary effusion lymphoma, plasmablastic lymphoma) or a related condition called multicentric Castleman disease that has come back or not improved after standard treatment. The drug targets a protein on cancer cells to help the immune system attack them. It might be a new option when standard chemotherapy isn't working or isn't suitable.
Bethesda, MarylandAges 18–120 - NCT05880108Recruiting
Behavior program to help COVID recovery in Veterans
This study tests whether a behavioral (lifestyle) program can improve recovery from COVID-19, especially for Veterans with different body weights. It looks at people who either have never had COVID before or had COVID more than 90 days ago.
Baltimore, MarylandAges Up to 80 years - NCT05887557Recruiting
Mobile HIV care for people struggling to stay in treatment
This study tests a low-barrier, mobile HIV care program designed with input from patients and other stakeholders to help people stay engaged in care and reach an undetectable viral load. It may help if you’re having trouble keeping regular HIV appointments or staying on treatment.
