Researchers are studying the safety and effectiveness of brenipatide, given alongside standard treatment, compared to a placebo with standard treatment, to see if it can delay the return of symptoms in adults with major depressive disorder. This is a Phase 3, randomized, double-blind study involving adult participants aged 18 to 75 years. The trial is designed to assess how long it takes for depression symptoms to relapse after starting the adjunctive treatment. Participants will receive either brenipatide or placebo, both administered by subcutaneous injection, in addition to their stable standard of care medication. The study has three main periods: a screening period lasting about one month, followed by a treatment phase of at least 12 months where participants receive the assigned injections, and finally a follow-up period of roughly two months. The total time in the study can be shorter if symptoms worsen or if a participant withdraws. During the trial, participants will need to attend scheduled visits, self-inject the study drug, maintain study diaries, and complete questionnaires. Researchers will monitor participants closely to determine the time until relapse of major depressive disorder symptoms occurs. Safety and adherence to study procedures will be tracked throughout the trial, with the primary outcome measuring the number of days from randomization until relapse.

Researchers are evaluating the safety and effectiveness of brenipatide combined with standard care compared to a placebo with standard care in adults with schizophrenia. This phase 2 study aims to understand how well brenipatide works as an additional treatment for schizophrenia and monitor any side effects. Participants eligible for the study must have schizophrenia and be on stable standard care medication. The trial consists of three main periods: a screening period lasting about one month, a treatment period that can last up to 12 months, and a follow-up period of approximately two months. During the treatment phase, participants receive either brenipatide or placebo administered by subcutaneous injection alongside their standard care. The study includes careful monitoring and adherence to study procedures such as self-injection, keeping diaries, and completing questionnaires. Participants will be involved in regular visits and assessments throughout the entire study duration, which may last up to 15 months. Researchers will measure changes in body weight from baseline to week 52 as a primary outcome. Participants will also be monitored for safety and efficacy through ongoing evaluations, including the use of electronic or paper diaries and required questionnaires to track their progress and response to treatment.

Researchers are evaluating overall survival in men with metastatic castration-resistant prostate cancer (mCRPC), a form of prostate cancer that has spread beyond the prostate and no longer responds to hormone therapies. This Phase 3 randomized trial compares pasritamig (JNJ-78278343), a T cell redirecting agent targeting human kallikrein 2, combined with best supportive care (BSC), against placebo with BSC to understand the length of time participants survive from the start of treatment. Participants receive pasritamig or placebo through intravenous infusion along with best supportive care, which is provided at the treating physician's discretion. The study focuses on men who have previously undergone multiple prostate cancer treatments including androgen-receptor pathway inhibitors, taxane chemotherapy, radioligand therapy, and possibly PARP inhibitors. Patients must continue ongoing hormone therapy during the treatment phase. During the study, participants are monitored for overall survival up to 2 years and 8 months. Assessments include clinical evaluations and laboratory tests to measure kidney and liver function, blood counts, and general health status. Safety and treatment effects are closely observed, with eligibility based on performance status and organ function. The trial aims to provide detailed long-term outcome data for this advanced prostate cancer treatment approach.

Researchers are evaluating the effectiveness of TAR-210 compared to a single-agent intravesical chemotherapy in adults with intermediate-risk non-muscle invasive bladder cancer (NMIBC) who have specific fibroblast growth factor receptor (FGFR) mutations or fusions. This phase 3 randomized study aims to compare disease-free survival between these treatments. Eligible participants must have a confirmed diagnosis of intermediate-risk NMIBC with certain risk factors and be willing to undergo multiple cystoscopies and assessments throughout the study. Participants will receive either TAR-210, which is delivered directly into the bladder, or one of the investigator-chosen intravesical chemotherapy drugs, including Gemcitabine or MMC, also administered into the bladder. Prior to randomization, visible tumors must be fully removed, and the absence of disease confirmed. The study includes a main study group and a substudy group with slightly different eligibility criteria based on tumor grade and risk factors. During the study, participants will be closely monitored through cystoscopies and surgical assessments (TURBT) to evaluate cancer recurrence or progression. The primary outcome measure is disease-free survival, tracked from randomization until the first documented cancer recurrence, progression, or death, over approximately four years and two months. Safety and treatment adherence will also be assessed throughout the study period.

Researchers are evaluating the combination of the investigational drug PF-06821497 (mevrometostat) with enzalutamide compared to enzalutamide alone in men with metastatic castration-resistant prostate cancer (mCRPC) who have not previously received androgen receptor signaling inhibitors (ARSi) or abiraterone. This global, multicenter Phase 3 study focuses on participants whose cancer has progressed despite androgen deprivation therapy (ADT) or first-generation anti-androgens but who have not started other systemic anti-cancer treatments for mCRPC. The study excludes those with prior treatment using enzalutamide, darolutamide, apalutamide, or abiraterone in any setting, though chemotherapy is allowed in the hormone-sensitive setting. The study includes a Screening Phase, followed by randomization where participants are assigned equally to one of two groups: one receiving PF-06821497 plus enzalutamide, and the other receiving placebo plus enzalutamide. All treatments are taken orally on a continuous basis. After the treatment phase, participants enter a Safety Follow-up and a Long-Term Follow-up period to monitor ongoing effects. Participants will undergo assessments during the study to evaluate radiographic progression-free survival over about three years. Researchers will collect imaging data such as bone scans and CT or MRI scans to monitor disease progression. Additional evaluations include performance status, life expectancy assessments, and safety monitoring for adverse events. The study duration spans from screening through treatment and follow-up phases to gather comprehensive data on the combination therapy's impact on mCRPC.

Researchers are evaluating the effect of muvalaplin on reducing cardiovascular risk in adults with elevated lipoprotein(a) levels who either have atherosclerotic cardiovascular disease or are at risk for a heart attack or stroke. This Phase 3, randomized, double-blind, placebo-controlled study focuses on adults with high Lp(a) levels and prior or potential cardiovascular events. The study aims to assess the time to the first major adverse cardiovascular event over about 5.25 years. Participants will be randomly assigned to receive either muvalaplin or a placebo, both administered orally. The study includes individuals with Lp(a) levels of at least 175 nanomoles per liter who have had a prior cardiovascular event within 10 years or are at risk for a first event due to conditions such as coronary artery disease, carotid stenosis, peripheral artery disease, high coronary artery calcium score, reduced kidney function with diabetes, or other high-risk factors. The treatment period lasts through the study duration, with close monitoring. During the study, participants will be regularly evaluated to track the occurrence of major adverse cardiovascular events, including heart attacks and strokes. Safety assessments will monitor blood pressure, kidney function, and heart failure status among other health indicators. The primary outcome measures the time to the first major cardiovascular event from baseline up to the end of the study, which spans approximately 5.25 years.

Researchers are evaluating the effectiveness and safety of a Double-effect kissing balloon technique (W-KBT) using Perfusion balloon (PB) and Drug coated balloon (DCB) in patients with left main coronary artery disease (LMD) who have left circumflex artery (LCx) ostium stenosis. This is a prospective, observational, multi-center study focusing on patients with stable angina, non-ST-elevation acute coronary syndrome, or unstable angina who are undergoing percutaneous coronary intervention (PCI). Patients who meet selection criteria will be enrolled and treated under usual care. The PCI procedure involves W-KBT following crossover stenting for the left main trunk to left anterior descending artery direction, proximal optimization technique (POT), and conventional kissing balloon technique (C-KBT) as the optimal treatment. Operators will obtain consent before performing PCI and will register cases continuously to assess the technique's efficacy and safety. Participants will undergo PCI with W-KBT, and data will be collected during the procedure to measure procedure success rates. Researchers will monitor major adverse cardiovascular events (MACE) within 12 months after PCI. The study will gather real-world data from multiple centers to evaluate the outcomes and safety of this treatment approach over time.

Researchers are evaluating the long-term safety and effectiveness of pembrolizumab (MK-3475) in participants with advanced solid tumors or blood cancers who have previously taken part in other pembrolizumab-based studies. This phase 3 study includes participants who are either currently on treatment or in follow-up from prior parent studies. It aims to understand how well pembrolizumab works over an extended period, up to approximately 10 years, by observing overall survival and safety outcomes. The study has three phases: First Course Phase, Survival Follow-up Phase, and Second Course Phase. Participants who were receiving pembrolizumab, pembrolizumab-based combinations, or lenvatinib in their parent studies will continue treatment in the First Course Phase, completing up to 35 doses every 3 weeks or 17 doses every 6 weeks. Those in the Follow-up Phase will enter the Survival Follow-up Phase without additional treatment but will be monitored. Participants eligible for a Second Course Phase, who have not received other anticancer treatments since their prior pembrolizumab dose and meet health criteria, may receive up to 17 doses every 3 weeks or 8 doses every 6 weeks of pembrolizumab or its combinations. Some may also receive other study drugs such as olaparib, MK-4280, MK-4280A, or pembrolizumab with berahyaluronidase alfa. Participants will be involved in regular treatment visits, safety checks, and long-term monitoring for up to about 10 years to assess overall survival. Researchers will evaluate clinical outcomes, monitor any side effects, and check organ function and physical health status. The study includes detailed eligibility screening, including physical assessments and adherence to contraception requirements for women of childbearing potential. Safety follow-up is ongoing to ensure participant well-being throughout the study.

Researchers are evaluating whether combining the investigational drug mevrometostat (PF-06821497) with enzalutamide works better than enzalutamide alone in men with metastatic castration-sensitive prostate cancer (mCSPC) who have not previously received androgen receptor pathway inhibitors or chemotherapy in this setting. This Phase 3, randomized, double-blind, placebo-controlled study involves participants who have only received limited prior androgen-deprivation therapy and no evidence of disease progression before starting the study. Participants will be randomly assigned to one of two groups: one group receives oral mevrometostat together with oral enzalutamide continuously, while the other group receives a placebo with oral enzalutamide continuously. The study includes a Screening Phase, a Treatment Phase after randomization, followed by Safety Follow-up and Long-Term Follow-up periods to monitor outcomes and side effects. Throughout the study, participants will undergo regular assessments including imaging scans to evaluate disease progression, laboratory tests, and monitoring of symptoms and adverse events. The main outcome measured is Radiographic Progression Free Survival (rPFS) over approximately 4 years from randomization. Safety and long-term effects will also be monitored to understand how well participants tolerate the treatments and how the disease responds over time.

Researchers are conducting a multicenter Phase III trial to compare two preoperative treatment approaches for locally advanced rectal cancer. The study aims to determine if adding irinotecan to a chemotherapy regimen after short-course radiation improves outcomes compared to chemotherapy without irinotecan. This approach, called total neoadjuvant therapy (TNT), may allow more patients with complete or near-complete clinical responses to avoid radical surgery and potentially preserve anorectal function and quality of life. Participants receive short-course radiation therapy (5x5 Gy) followed by chemotherapy cycles. One group receives six cycles of CAPOX chemotherapy (capecitabine and oxaliplatin), while the other group receives six cycles of CAPOXIRI chemotherapy (capecitabine, oxaliplatin, and irinotecan). After finishing treatment, patients are restaged: those with incomplete response undergo surgery, those with complete response receive non-operative management, and those with near-complete response receive treatment decided by their physician with committee guidance. Follow-up includes CT scans, MRI, colonoscopy, and blood tests every 4 months for 2 years, then every 6 months up to 5 years. During the study, participants undergo regular imaging and biopsies to monitor disease status and organ preservation. The main outcome measured is disease-free survival adapted to organ preservation over 3 years. Safety and treatment effects will be closely observed throughout the trial. The total enrollment aims for 608 patients to adequately assess differences between the two treatment approaches, with careful monitoring for cancer recurrence and patient well-being over several years.
