Long-acting IL-7 drug trial for low CD4 immune cells
This Phase 1/2 study tests a long-acting IL-7 medicine to raise low CD4 immune cells in people with idiopathic CD4 lymphopenia. Because this is a dose-escalation study, the goal is to check safety and see if the treatment affects immune cell levels.
Bethesda, MarylandAges 18–75 - NCT05592626RecruitingPhase 1/Phase 2
T cell activator STAR0602 for advanced solid tumors
This study tests an experimental drug called STAR0602 that aims to boost your immune system's T cells to fight advanced solid tumors. It's for patients whose cancer has not responded to standard treatments or for whom such treatments are not suitable.
Sacramento, CaliforniaAges 18 years+ - NCT05603728Recruiting
Follow-up study for Exactech shoulder implants after surgery
This study follows people who get (or already had) a shoulder replacement to see how the implant is doing over time. It may help improve future care by tracking long-term performance and safety.
Laguna Woods, CaliforniaAges 21 years+ - NCT05624450RecruitingPhase 3
Test drug tozorakimab for hospitalized viral lung infection needing oxygen
This Phase 3 study tests tozorakimab to see if it helps people hospitalized with a viral lung infection that is causing low oxygen levels. You might qualify if you still need supplemental oxygen when the study starts.
Birmingham, AlabamaAges 18 years+ - NCT05604430Enrolling by invitation
Study of pre-hospital breathing support with a specific ventilator
This study looks at breathing support given outside the hospital using a particular ZOLL ventilator model and software version. If you were treated with the right equipment, the team will use the ventilator’s recorded data to evaluate how ventilation was delivered.
Hartford, ConnecticutAges Any age - NCT05631405Recruiting
Dexamethasone for serious dengue with warning signs
This trial studies whether dexamethasone (a steroid medicine) can help people with dengue infection who have warning signs and are still in the fever stage. It may help reduce complications like breathing problems, severe bleeding, or organ stress, but it is only for a specific window and situation.
BangkokAges 7–99 - NCT05633056Recruiting
Testing TB medicines for people with drug-resistant TB and HIV
This trial studies a treatment plan for people who have both drug-resistant tuberculosis (TB) and HIV. It focuses on starting a specific TB medication (bedaquiline) and, if needed, HIV treatment soon after enrollment to see what approach works best.
Durban, KwaZulu-NatalAges 18 years+ - NCT05630638RecruitingPhase 4
Doravirine dose testing during pregnancy for breastfeeding mothers
This study tests how to best dose doravirine for pregnant people with HIV who plan to breastfeed after delivery. The goal is to keep the HIV treatment working safely for both pregnancy and breastfeeding.
Cape TownAges 18 years+ - NCT05635591Enrolling by invitationPhase 1
KSD-101 vaccine trial for EBV-related blood cancers
This early-phase trial studies KSD-101 (a vaccine treatment) for people whose blood cancers are linked to EBV and who have not responded or have relapsed after standard treatment. It may help your immune system better control the cancer, especially when other options have already been tried.
Wuhan, HubeiAges 18–70 - NCT05634733Recruiting
Testing how a heart ultrasound finding changes in sepsis treatment
This study looks at how a measurement from a bedside heart ultrasound changes while treating people with sepsis or septic shock. It may help doctors understand how to monitor response to treatment using a quick ultrasound test.
Baltimore, MarylandAges 18 years+ - NCT05616130Recruiting
Study of abnormal blood immune activation after trauma or elective hip surgery
This study looks at how the body’s blood-related immune system “switches on” in unusual ways after a major injury or elective hip repair. The researchers hope this helps them understand who is at risk for complications and why, by measuring changes in your blood around the time of surgery or hospital treatment.
Gainesville, FloridaAges 18–100 - NCT05597280RecruitingPhase 3
Medicine given after exposure to prevent leprosy
This Phase 3 study tests whether taking preventive antibiotics after possible contact can stop leprosy from developing. If it works, it could protect people in affected communities from getting leprosy (and possibly related infections).
MoroniAges 2 years+ - NCT05603650Recruiting
Mouthwash study for healthy bacteria in your mouth and gut
This study tests how a mouthrinse changes the helpful bacteria in your mouth and stomach/gut. You may need several visits and phone follow-ups to see how your microbiome shifts over time.

Compare automatic versus as-needed follow-up after common infections
This study compares two ways of scheduling a check-up after a child is hospitalized: an automatic visit or a visit only if needed (“as-needed”). It may help families and clinicians see which follow-up approach works best after illnesses like pneumonia, stomach flu (gastroenteritis), skin infections, or urinary tract infections.

Rio de JaneiroAges 18 years+ - NCT05580458RecruitingPhase 1/Phase 2
Shingles vaccine study for adults with well-controlled HIV
This Phase 1/2 study tests how safe and how well a shingles (varicella zoster) vaccine works in adults living with HIV whose immune status is measured by CD4 count, plus a healthy comparison group. It may help researchers understand whether the vaccine can safely boost protection in people with HIV.
Bethesda, MarylandAges 18 years+ - NCT05583708RecruitingPhase 2
Trial tests targeted radiation plus immunotherapy after anti–PD-1 failure
This Phase 2 trial studies whether peptide receptor radionuclide therapy (targeted radiation) combined with immunotherapy (pembrolizumab) can shrink Merkel cell cancer after it has grown despite anti–PD-1/L1 treatment. It may help people whose cancer has specific receptors that make them eligible for the targeted radiation.
