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.
NCT05593497
The purpose of this study is to learn about how an investigational drug intervention completed before doing prostate surgery (specifically, radical prostatectomy with lymph node dissection) may help in treatment of high risk localized prostate cancers that are most resistant to standard treatments. This is a phase II research study. For this study, capivasertib, the study drug, will be taken with intensified androgen deprivation drugs (iADT; abiraterone and leuprolide) prior to radical prostatectomy. This study drug treatment will be evaluated to see if it is effective in shrinking and destroying prostate cancer tumors prior to surgery and to further evaluate its safety prior to prostate cancer surgery.
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.
NCT04199104
This is a study of pembrolizumab (MK-3475) with or without lenvatinib (E7080/MK-7902) as a first line intervention in a PD-L1 selected population with participants with recurrent or metastatic head and neck squamous cell carcinoma. Hypotheses include: * Pembrolizumab + lenvatinib is superior to pembrolizumab + placebo with respect to Objective Response Rate (ORR) per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) by blinded independent central review (BICR). * Pembrolizumab + lenvatinib is superior to pembrolizumab + placebo with respect to Progression Free Survival (PFS) per RECIST 1.1 as assessed by BICR. * Pembrolizumab + lenvatinib is superior to pembrolizumab + placebo with respect to overall survival (OS).

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).
NCT07204964

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.
NCT05064293
The randomized, two-arm pragmatic trial will test the effectiveness of offering 6-months of telephonic support from a mental health (MH) navigator to promote early access, engagement, coordination, and personalization of mental health treatment and services for children naïve to such treatments and services, and who are identified as being at risk for behavioral health concerns. The model includes: (a) automated identification of early symptoms for children meeting criteria for behavioral health problems using a previously developed Natural Language Processing (NLP) program and predictive algorithm; (b) standardized instruments for assessment and diagnosis of mental health disorders (c) 30 minute assessment appointments with a study psychologist (d) creation of an Epic "reporting workbench" and Epic "smart form" to facilitate the outreach, monitoring and follow-up of families/children by the MH navigator; (e) use of MH Navigators (e.g., clinical social workers) to conduct family outreach, and coordination with and between clinicians; and (f) the offer of one to four clinic-to-home videoconferencing brief therapy sessions to bridge families/children unwilling or unable to access in-person MH services.

All placebo subjects who opt to continue will transition to active drug during the OLE Period.
NCT02387736
Standard one-year dialectical behaviour therapy (DBT), which has four components, is an effective treatment for people with borderline personality disorder. However, such DBT programs are in short supply and costly, resulting in long wait lists. In practice, DBT is often reduced in length or intensity. This study will determine whether shorter DBT treatment is clinically effective and cost-effective. In total, 240 self-harming BPD patients will be randomly assigned to receive either 1 year or 6 months of DBT, with follow-up lasting two years. Rates of suicidal and self-harm behaviours, use of health care and general psychological functioning will be examined.
