Researchers are evaluating treatments for breast cancer that is hormone receptor-positive (HR+) and human epidermal growth factor receptor 2-negative (HER2-), specifically in cases where the cancer is either locally advanced and cannot be removed by surgery or has spread to other parts of the body (metastatic). The study aims to determine if patritumab deruxtecan (also called HER3-DXd or MK-1022) helps patients live longer overall or without the cancer growing compared to chemotherapy or trastuzumab deruxtecan. This is a Phase 3 clinical trial focusing on this particular type of breast cancer. Participants receive one of several treatments: patritumab deruxtecan through intravenous infusion, chemotherapy options like paclitaxel or nab-paclitaxel via IV, oral capecitabine tablets, liposomal doxorubicin via IV, or trastuzumab deruxtecan via IV infusion. The study compares the effects of patritumab deruxtecan alone to the treatment chosen by the physician. Treatments are administered according to standard dosing schedules during the trial. During the study, participants are monitored for how long they live without the cancer progressing (up to about 45 months) and overall survival (up to about 85 months). Researchers assess disease status through imaging and other evaluations. Participants have regular check-ups to monitor health, treatment effects, and any side effects. The study tracks treatment response and safety over the extended follow-up period to understand the benefits and risks of the therapies.

Primary immune thrombocytopenia (ITP) is a condition in which the immune system mistakenly destroys platelets, the cells that help stop bleeding. This leads to a low platelet count, making it easier to bruise or bleed. The trial investigates the long-term safety, tolerability, and effectiveness of mezagitamab in adults with chronic primary ITP who have previously participated in certain mezagitamab studies. It also examines how the body processes mezagitamab over time. Participants who completed the previous mezagitamab studies TAK-079-3002 or TAK-079-1004 and meet specific criteria will receive mezagitamab as a subcutaneous injection during this continuation study. The study is open-label and multicenter, focusing on continued treatment based on protocol requirements. The medication is given under medical supervision, and participants return to the study clinic several times throughout the study. During their participation, individuals will undergo regular assessments including monitoring for treatment-emergent adverse events and serious adverse events up to approximately 108 weeks. Researchers will track safety by noting any adverse events that lead to permanent withdrawal from mezagitamab. The study includes physical evaluations, laboratory tests, and ongoing safety monitoring to understand how well participants tolerate the treatment and how effective it is over the long term.

Researchers are evaluating the safety and expression of delandistrogene moxeparvovec, a gene transfer therapy, in males with Duchenne Muscular Dystrophy (DMD). This open-label Phase 1 study includes participants across different cohorts based on ambulatory status and age. Enrollment for Cohorts 1 through 7 is complete, and Cohort 8 is currently enrolling new participants. Participants receive a single intravenous infusion of delandistrogene moxeparvovec. The study involves multiple cohorts differentiated by age and motor function abilities, including ambulatory and non-ambulatory participants. Some cohorts require stable glucocorticoid use, while others do not yet require steroid treatment. Cohort 8 participants must meet specific motor function scores and are monitored for specific safety concerns such as acute liver injury. Throughout the study, participants undergo assessments including measurement of dystrophin expression by Western blot at baseline and week 12. Safety monitoring includes tracking acute liver injury up to week 72 for Cohort 8. The total participation duration can be up to 156 weeks. The study evaluates changes in dystrophin protein levels as the primary outcome, along with safety and tolerability of the gene therapy over time.

Researchers are evaluating the safety and effectiveness of rilvegostomig compared to pembrolizumab, both combined with platinum-based doublet chemotherapy, as initial treatments for patients with metastatic non-squamous non-small cell lung cancer (mNSCLC) whose tumors express PD-L1. This Phase III, randomized, double-blind, global study focuses on patients whose tumors meet the PD-L1 expression threshold of 1% or higher and do not have certain genetic mutations or rearrangements that would require other targeted therapies. Participants receive either rilvegostomig or pembrolizumab intravenously on the first day of each 21-day treatment cycle. Both groups also receive platinum-based chemotherapy drugs such as carboplatin or cisplatin, administered intravenously up to four cycles, along with pemetrexed given intravenously on Day 1 of each cycle. The study monitors these treatments as first-line therapy for metastatic non-squamous NSCLC. During the study, participants undergo regular assessments including imaging scans to measure tumor size and response, as well as evaluations of organ and bone marrow function. Researchers track overall survival and progression-free survival for up to approximately five years. Safety is closely monitored throughout, and patients are followed long-term to assess outcomes related to treatment effectiveness and tolerability.

Researchers are evaluating the safety and effectiveness of pulsed field ablation (PFA) therapy for treating persistent atrial fibrillation (PersAF) that does not respond to medication. The study compares PFA targeting pulmonary veins plus extra-PV sources identified by electrographic flow (EGF) mapping against PFA targeting pulmonary veins plus the left atrial posterior wall (PVI + PWA). The goal is to establish safety and to show that the new method is not less effective than the current approach in patients with symptomatic, drug-refractory PersAF. Participants will receive treatment using several devices, including the FARAPOINT Pulsed Field Ablation System, the OptiMap System for electrogram analysis, and the FARAWAVE NAV Catheter combined with the Opal HDx Mapping System for detailed heart mapping. All subjects will undergo electroanatomical mapping of the entire left atrium, followed by pulsed field ablation of the pulmonary veins, with additional ablation of either EGF-identified sources or the posterior wall, depending on the assigned treatment group. During the study, participants will be monitored for safety outcomes at 60 days and effectiveness outcomes at 365 days. They will receive a LUX-Dx insertable cardiac monitor to track heart rhythm continuously. Researchers will collect clinical data, imaging, and follow-up assessments to evaluate treatment impact and safety. The study includes ongoing follow-up visits to ensure thorough monitoring of heart function and study outcomes over one year.

The trial investigates the use of volrustomig in participants with unresected locally advanced head and neck squamous cell carcinoma (LA-HNSCC) who have not shown disease progression after receiving definitive concurrent chemoradiotherapy (cCRT). The study aims to evaluate the efficacy and safety of volrustomig compared to observation in this patient population. Participants have tumors that express PD-L1 and the study is conducted as a Phase III, randomized, open-label, multi-center global trial. Participants are assigned to receive either volrustomig as sequential therapy following cCRT or to an observation group. The treatment period involves monitoring participants who have completed definitive cCRT but remain unresected and have no evidence of metastatic disease. The study focuses on participants with Stage III, IVA, or IVB LA-HNSCC according to AJCC criteria, who have not undergone tumor resection before cCRT and have not been treated with radiotherapy alone. During the study, participants are regularly evaluated for progression-free survival, with follow-up lasting up to approximately 8 years to assess long-term outcomes. Researchers will monitor safety and disease progression closely. The overall participation duration includes screening, treatment or observation, and extended follow-up to capture both efficacy and safety data over time.

The purpose of this study is to assess the long-term safety and tolerability after an intravitreal injection (a shot of medicine into the eye) of JNJ-81201887 administered in parent clinical studies.

Researchers are conducting a long-term observational study to evaluate the safety and effectiveness of SKG0106 in treating patients with neovascular (wet) age-related macular degeneration (nAMD). This study follows individuals who completed earlier related clinical trials, focusing on ongoing monitoring for up to five years after receiving the SKG0106 injection. The goal is to gather detailed information on the treatment’s impact and any potential side effects over an extended period. The study involves no new interventions but includes regular safety and efficacy assessments for participants who previously received SKG0106. These assessments will happen throughout the five-year follow-up, allowing researchers to observe the long-term outcomes without altering the patients’ treatment plans. The observational nature of the study means it focuses on the natural progression and response to the existing treatment. Participants will undergo various evaluations during the follow-up period to monitor eye health and overall safety. Researchers will track the type, severity, and occurrence of any ocular or systemic adverse events, including serious or special interest events, for up to five years after the initial SKG0106 injection. This thorough monitoring aims to provide comprehensive data on treatment safety and patient well-being over time.

Researchers are evaluating whether the drugs retatrutide and tirzepatide can prevent major adverse liver outcomes (MALO) in adults with metabolic dysfunction-associated steatotic liver disease (MASLD) who are at high risk. This Phase 3 trial enrolls about 4,500 adults with MASLD identified by non-invasive tests indicating an increased likelihood of developing serious liver problems. The study aims to understand how these treatments might affect liver health over time compared to a placebo. Participants will be randomly assigned to receive either retatrutide, tirzepatide, or a placebo, all given by subcutaneous injection. The study will last approximately 224 weeks, during which participants may attend 25 to 30 clinic visits for monitoring and assessment. After the main study, eligible participants can join an optional 2-year extension where all will receive either retatrutide or tirzepatide regardless of their original group. Throughout the trial, participants’ liver function and disease progression will be closely monitored through various health assessments. Researchers will track the time to the first major adverse liver event as the main outcome. Safety and health status will be evaluated regularly during clinic visits, ensuring thorough observation over the long study period.

Researchers are evaluating a phase 1/2 open-label study to investigate the safety, pharmacokinetics, pharmacodynamics, and clinical effects of an oral drug called Enzomenib (DSP-5336) in patients with acute leukemia, including relapsed or refractory acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL), ambiguous lineage acute leukemia, and in certain sites, high-risk myelodysplastic syndromes (MDS) or relapsed multiple myeloma (MM). The study also examines Enzomenib combined with standard AML treatments such as venetoclax plus azacitidine and the intensive chemotherapy 7+3 regimen in patients newly diagnosed with AML who have specific genetic mutations (MLL rearrangement or NPM1 mutation). Participants receive oral Enzomenib either alone or combined with other drugs: venetoclax and azacitidine for a nonintensive treatment group, gilteritinib for a certain relapsed AML group, or intensive chemotherapy with cytarabine and daunorubicin (7+3) for newly diagnosed AML patients. The study includes dose escalation and expansion phases to determine recommended doses for phase 2. Treatment schedules and doses are adjusted based on response and safety, with some patients enrolled in specialized cohorts according to their genetic markers. Throughout the study, participants undergo regular assessments including clinical exams, laboratory tests, bone marrow samples for genetic analysis, and monitoring for adverse events. Researchers measure safety outcomes such as adverse and serious adverse events, determine optimal dosing for phase 2, and evaluate treatment effectiveness by tracking complete response rates. Safety is monitored up to 30 days after the last dose, with dose recommendations made within four months of treatment start and response assessed around six months. The total participation time varies based on individual treatment and study phase.
