Houston, TexasAges 18 years+ - NCT05636540RecruitingEarly Phase 1
PET/CT scan test for a tumor protein in these rare tumors
This early study uses a special PET/CT scan to see how much a specific cancer-related protein (PARP-1) is present in pheochromocytoma and paraganglioma. It may help doctors understand the biology of these tumors and how useful this scan could be in the future.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05668026RecruitingPhase 1/Phase 2
Venetoclax to shrink HIV reservoir in people on stable ART
This Phase 1/2 study tests whether venetoclax can help reduce the “HIV reservoir,” which is a hidden group of HIV-infected cells, while you stay on your usual HIV treatment. It also looks at whether the drug helps these infected cells die off in a controlled, safe way.
Melbourne, MelbourneAges 18–65 - NCT05614739RecruitingPhase 1
Study of vepugratinib for cancers with FGFR3 gene changes
This study tests a new pill, vepugratinib, for people whose cancer has a specific change in a gene called FGFR3. The drug targets this gene change to try to slow or shrink the cancer, and may be an option if standard treatments have not worked.
Tucson, ArizonaAges 18 years+ - NCT05590455RecruitingPhase 2
Testing a TNF-blocking drug to reduce death in HIV and TB meningitis
This Phase 2 trial studies whether a TNF-blocking medicine can lower the risk of death in people with HIV who also have TB meningitis. You would receive standard TB meningitis treatment plus the study drug, if you meet the criteria.
Rio de JaneiroAges 18 years+ - NCT05584397Enrolling by invitation
Compare immune activity and HIV hidden reservoir on two treatments
This study compares how active the immune system is and how large the “hidden” HIV reservoir is in people on two different HIV treatment types. It may help researchers understand whether staying on a tenofovir-containing regimen leads to better control of HIV hiding in the body.
Seattle, WashingtonAges 18–65 - NCT05511363RecruitingPhase 3
Study of a new medicine for psychosis in Alzheimer's disease
This trial tests a new drug called KarXT to see if it can safely reduce hallucinations and delusions in people with Alzheimer's disease. If you or a loved one has Alzheimer's and experiences these symptoms, this study might offer a new treatment option.
