NCT07029711
The purpose of this study is to learn about the safety and effects of the study medicine (called ritlecitinib) for the possible treatment of severe alopecia areata. Alopecia areata is a condition that causes hair loss. This study is seeking participants who have: * at least 50% scalp hair loss due to alopecia areata. * received varicella vaccination (2 doses) or have been infected by varicella zoster virus before based on blood test reports. * history of clinical response failure to alopecia areata treatment (for children in EU/UK only). All participants in this study will receive either study medicine (ritlecitinib) or placebo. A placebo does not have any medicine in it but looks just like the medicine being studied. One-third of participants will receive ritlecitinib higher dose, one-third participants will receive ritlecitinib lower dose, and one-third participants will receive placebo. The study medicine is a capsule that is taken by mouth. It is taken once each day at home. The study will compare the experiences of participants receiving ritlecitinib to participants receiving placebo. This will help see if ritlecitinib is safe and effective. Participants will take part in this study for 6 months. During this time, they will have 8 study visits at the study clinic. The study team will also call participants about 8 times over the phone.
NCT06072183
The purpose of this study is to learn about the safety and effects of the study medicine ritlecitinib for the possible treatment of nonsegmental vitiligo. Vitiligo causes white patches on your skin when the cells that give your skin color are destroyed. Nonsegmental means that it can affect both sides of the body such as both knees and both hands. Ritlecitinib has been tested in earlier clinical studies and has a favorable safety profile. At present there are no approved medications taken by mouth to treat nonsegmental vitiligo. This study is seeking participants who: * Are 18 years of age or older. * are confirmed to have nonsegmental vitiligo for at least 3 months. * Are willing to stop all other treatments that they may be taking for vitiligo. In this study participants will be chosen by chance, like drawing names out of a hat to receive 1 of 3 treatments: •Part I where two different amounts of ritlecitinib (50 mg and 100 mg) are taken once daily. It will be compared to placebo. Placebo is a dummy capsule. It doesn't have any medicine used in the study. Participants receiving placebo who have not responded to treatment after 52 weeks will be given 100 milligrams or 50 milligrams of ritlecitinib for the remaining 52 weeks of the study. • In Part II, participants will only receive 100 milligrams of ritlecitinib. About 1000 participants will take part in Part I and around 450 in Part II globally. The study will compare the experiences of people receiving ritlecitinib to those of the people who do not. This will help see if ritlecitinib is safe and effective. People in Part I will be in this study for about 26 months and people in Part II will be in this study for about 14 months. During the study, participants in part I will need to visit the study site at least 17 times. In part II, participants will visit at least 11 times. Participants will undergo various tests and procedures such as: * vitiligo rating, * physical examinations, * hearing tests, * blood tests, * x-ray, * ECG, * photographs of areas with vitiligo. Participants will be asked to complete questionnaires about their vitiligo.
NCT04195555
This phase II Pediatric MATCH trial studies how well ivosidenib works in treating patients with solid tumors, including central nervous system tumors, lymphomas and histiocytic disorders that have not responded to (refractory) or have come back after (recurrent) prior treatment that have IDH (isocitrate dehydrogenase) 1 genetic alterations (mutations). Ivosidenib may block the growth of cancer cells that have specific genetic changes in an important signaling pathway called the IDH pathway.
NCT06817356
The objective of this proof-of-concept study to evaluate mazdutide in participants with alcohol use disorder (AUD). For any individual participant, the maximum duration of study participation is approximately 36 weeks, including screening and posttreatment follow-up.
NCT05287113
The purpose of this study is to evaluate the safety and efficacy of the combination of retifanlimab plus INCAGN02385 and retifanlimab plus INCAGN02385 and INCAGN02390 compared with retifanlimab alone as first-line treatment in PD-L1-positive and systemic therapy-naive recurrent/metastatic (R/M) squamous cell carcinoma of the head and neck (SCCHN).
NCT02477696
This study is designed to evaluate progression-free survival (PFS) endpoint for acalabrutinib versus (vs) ibrutinib in previously treated chronic lymphocytic leukemia.
NCT03328026
This is an open-label, phase I/II double arm study of the SV-BR-1-GM regimen in combination with retifanlimab in patients with metastatic or locally recurrent breast cancer who have failed standard therapy. Patients will receive the SV-BR-1-GM regimen with combination immunotherapy. There will be an initial evaluation of the combination of the SV-BR-1-GM regimen with retifanlimab every 3 weeks. If this is found to be safe and well tolerated in a cohort of at least 12 patients (dose-limiting toxicities (DLTs) in less than 30% of the patients evaluated), then an expansion cohort of up to 24 patients will be treated with that combination. These will be randomized to two regimens differing in the timing of checkpoint inhibitor administration.
NCT06295809
This is a two-part (Phase 2/Phase 3) study of intismeran autogene, an individualized neoantigen therapy (INT), plus pembrolizumab in participants with locally resectable advanced cutaneous squamous cell carcinoma (LA cSCC). Phase 2 has three arms intismeran autogene plus pembrolizumab given as neoadjuvant and adjuvant treatment with standard of care (SOC), standard of care (surgical resection with/without adjuvant radiation therapy (RT) only at investigator's discretion) and pembrolizumab monotherapy given as neoadjuvant and adjuvant treatment with SOC. This phase will assess the safety and efficacy of intismeran autogene in combination with pembrolizumab as neoadjuvant and adjuvant therapy in participants with resectable LA cSCC as compared to standard of care SOC only. The primary hypothesis is that intismeran autogene plus pembrolizumab with SOC is superior to SOC only with respect to event free survival (EFS) as assessed by the investigator. Phase 3 expansion will be determined by prespecified Go-No-Go decision in which 412 additional participants will be randomized to intismeran autogene plus pembrolizumab with SOC and SOC only, without changing the inclusion/exclusion criteria for the additional enrollment or study endpoints. As of Amendment 04, enrollment was stopped and there will be no Phase 3 expansion.
NCT05422222
The purpose of this study is to evaluate the pharmacokinetics, safety, tolerability and efficacy of VX-121/tezacaftor/deutivacaftor (VX-121/TEZ/D-IVA) in CF participants with at least 1 triple combination responsive (TCR) mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene.
NCT04544449
A study to evaluate the efficacy and safety of fenebrutinib on disability progression in adult participants with Primary Progressive Multiple Sclerosis (PPMS). All eligible participants will be randomized 1:1 to either daily oral fenebrutinib (and placebo) or intravenous (IV) ocrelizumab (and placebo) in a blinded fashion through an interactive voice or web-based response system (IxRS). 985 participants were enrolled and recruited globally. Participants who discontinue study medication early or discontinue from the study will not be replaced. The Open-Label Extension (OLE) phase is contingent on a positive benefit-risk result in the Primary Analysis of the study.
NCT06657768
The main purpose of this study is to evaluate the safety and tolerability of the study drug known as LY4006895. Part A will administer a single-ascending dose in healthy participants or Part B will administer multiple-ascending doses in participants with early symptomatic Alzheimer's Disease (AD). Blood tests will be performed to check how much LY4006895 gets into the bloodstream and how long it takes the body to eliminate it. This is a 2-part study and will last approximately 29 weeks for Part A and 61 weeks for Part B, including a screening period for each part.
NCT02122185
This randomized phase II trial studies how well metformin hydrochloride and combination chemotherapy works in treating patients with stage III-IV ovarian, fallopian tube, or primary peritoneal cancer. Drugs used in chemotherapy, such as carboplatin, paclitaxel and docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Metformin hydrochloride may help carboplatin, paclitaxel and docetaxel work better by making tumor cells more sensitive to the drugs. Studying samples of blood and tissue in the laboratory from patients receiving metformin hydrochloride may help doctors learn more about the effects of metformin hydrochloride on cells. It may also help doctors understand how well patients respond to treatment. Giving metformin hydrochloride together with combination chemotherapy may kill more tumor cells.
NCT03793140
The purpose of this study is to test any good and bad effects of the study drug, CPI-613.
NCT02520791
This phase I trial studies the side effects and best dose of anti-inducible T-cell co-stimulator (ICOS) monoclonal antibody MEDI-570 in treating patients with peripheral T-cell lymphoma follicular variant or angioimmunoblastic T-cell lymphoma that has returned after a period of improvement (relapsed) or has not responded to previous treatment (refractory). Immunotherapy with monoclonal antibodies, such as anti-ICOS monoclonal antibody MEDI-570, may induce changes in the body's immune system and may interfere with the ability of tumor cells to grow and spread.
NCT07204964
The purpose of this study is to assess the reactogenicity, safety and immune response of GlaxoSmithKline's (GSK) messenger RNA (mRNA)-based multivalent seasonal influenza vaccine candidates administered in healthy younger and older adults.
NCT06921850
The purpose of the study is to assess the PK of bimekizumab following subcutaneous (sc) administration in study participants with moderate to severe hidradenitis suppurativa (HS)
NCT05768932
This study is a multiple cohort, multicenter, open-label Phase 1 study with dose-escalation substudies investigating intravenous (IV) BAL0891 as monotherapy, and in combination with tislelizumab or paclitaxel, to determine the safety and tolerability of increasing doses of BAL0891 in patients with advanced solid tumors or relapsed or refractory acute myeloid leukemia. An adaptive model-based design will be used to guide the dose escalation. Subject assignment to Substudy 1, 2, 3 and 4 will be finalized following approval from the investigator and sponsor. The dose-expansion stage will be conducted with the RP2D to further evaluate the preliminary anti-tumor activity, safety, and tolerability in metastatic TNBC and GC.
NCT05896163
The purpose of this study is to learn about the effects of two study medicines (maplirpacept \[PF-07901801\] and glofitamab) when given together for the treatment of diffuse large B-cell lymphoma (DLBCL) that is relapsed or is refractory. Relapsed means has returned after last treatment. Refractory means that it has not responded to last treatment. The two study medicines are given after a single dose of obinutuzumab which is the third study medicine. DLBCL is a type of non-Hodgkin lymphoma (NHL). NHL is a cancer of the lymphatic system. It develops when the body makes abnormal B lymphocytes. These lymphocytes are a type of white blood cell that normally help to fight infections. This study is seeking adult participants who: * Have histologically confirmed diagnosis of DLBCL * Have received at least two first lines of treatment for NHL. * Are unable or unwilling to undergo a stem cell transplant or CAR-T cell therapy. Stem cell transplant is a procedure in which a patient receives healthy blood-forming cells to replace their own stem cells that have been destroyed by treatment. A CAR-T therapy is a type of treatment in which a patient's T cells are changed in the laboratory so they will attack cancer cells. Everyone in this study will receive all three medicines at the study site by intravenous (IV) infusion which is given directly into a vein. The two study medicines (maplirpacept \[PF-07901801\] and glofitamab) will be given in 21-day cycles. At Cycle 0, participants will receive a single dose of obinutuzumab pre-treatment followed by two step-up doses of glofitamab. The combination of maplirpacept (PF-07901801) with glofitamab full dose will be administered for the first time at Cycle 1 Day 1. Maplirpacept (PF-07901801) will be given weekly for the first three cycles and then every three weeks. Glofitamab will be given every 3 weeks for approximately 9 months. Thereafter participants will continue to receive maplirpacept alone. Maplirpacept (PF-07901801) will be given at different doses to different participants. Everyone taking part will receive the same fixed doses of glofitamab and obinutuzumab studied in patients with DLBCL. The study will compare the experiences of people receiving different doses of maplirpacept (PF-07901801). This will help to determine what dose is safe and effective when given with the other 2 study medicines.
NCT05840159
This is a Phase 4 blinded, randomized, active-controlled, non-inferiority trial. Final evaluable population will include a minimum 596 individuals: 298 women with confirmed urogenital chlamydia (CT) and 298 men with confirmed rectal chlamydia (CT). Approximately 664 participants will be enrolled to achieve a minimum 596 participants who contribute primary outcome data. Randomization will be stratified by study site and sex: 332 women and 332 men. Participants will be randomized 1:1 to a 3-day regimen of doxycycline or a 7-day regimen of doxycycline. The study blind will be maintained by providing 7 days of identical pre-filled blister packs, one with 3 days of active treatment and 4 days of placebo, and the other with 7 days of active treatment. Participants will be asked to return 28 days after randomization (at day 29), at which time they will be re-tested for chlamydia (CT) using a laboratory-based chlamydia (CT) nucleic acid amplification test (NAAT).
NCT07037771
This multicenter, randomized, placebo-controlled study will evaluate the efficacy and safety of zodasiran subcutaneous (SC) injection in subjects 12 years of age and older with genetically or clinically diagnosed Homozygous familial hypercholesterolemia (HoFH). After completion of the double blind (DB) treatment period subjects will be eligible to continue in the optional open-label extension (OLE) period of the study. All placebo subjects who opt to continue will transition to active drug during the OLE Period.
