Researchers are studying metastatic castration-resistant prostate cancer mCRPC to find new treatment options. This trial evaluates if the study medicine ifinatamab deruxtecan I-DXd or MK-2400 helps people live longer overall and experience slower cancer growth or spread compared to chemotherapy. The study is a Phase 3 trial comparing I-DXd with standard chemotherapy for mCRPC patients. Participants are randomly assigned to receive either I-DXd at 12 mgkg every 3 weeks through intravenous infusion or docetaxel chemotherapy at 75 mgm2 every 3 weeks combined with daily prednisone pills. Treatment continues until the disease progresses, unacceptable side effects occur, or treatment is stopped for other reasons. Premedication is given before each dose of I-DXd to help prevent nausea and vomiting. During the study, participants will have regular visits for treatment and monitoring. Researchers will assess overall survival and radiographic progression-free survival for up to about 36 months. Additional measures include response rates, time to pain progression, PSA progression, and adverse events. The study tracks safety, treatment effects, and quality of life over a long follow-up period to better understand the potential benefits and risks of I-DXd compared to chemotherapy.

Researchers are evaluating camizestrant against standard endocrine therapy for patients with ER-positive, HER2-negative early breast cancer who have an intermediate or high risk of disease recurrence. These patients must have completed locoregional therapy and at least 2 to 5 years of standard adjuvant endocrine therapy. The study is a Phase III open-label trial focused on improving outcomes for these patients over a long-term period. Participants are randomly assigned to receive either camizestrant orally or continue with the standard endocrine therapy chosen by their investigator, which may include aromatase inhibitors exemestane, letrozole, anastrozole or tamoxifen. Treatment in each group lasts for 60 months. The study allows prior use of CDK46 inhibitors and includes a follow-up period extending up to 10 years from the last patient randomization. During the study, participants will undergo regular assessments to monitor invasive breast cancer-free survival and other outcomes such as invasive disease-free survival, distant relapse-free survival, overall survival, and safety. Researchers will also evaluate symptoms like joint pain, hot flushes, and vaginal dryness using specific scales, along with quality of life measures and pharmacokinetics. Safety monitoring continues up to 28 days after the last dose, and participants remain under observation for up to 10 years total.

Researchers are evaluating ibuzatrelvir, an oral medication, to determine its effectiveness and safety in adults and adolescents aged 12 years and older with COVID-19 who are not hospitalized but are at high risk for severe illness. The study is a phase 3, randomized, double-blind trial comparing ibuzatrelvir with a placebo. Participants must have confirmed SARS-CoV-2 infection with symptoms starting within 5 days and meet specific risk factor criteria based on age. Eligible participants will be randomly assigned to receive either ibuzatrelvir or a matching placebo twice daily by mouth for 5 days. The study allows co-administration of standard care treatments available locally. The total study duration is about 6 months, including follow-up. Participants will be monitored for emergency department visits related to COVID-19, hospitalizations, and mortality up to 28 days after starting treatment. Additional evaluations include symptom resolution, occurrence of long COVID symptoms, viral RNA levels, and safety measures such as adverse events through 24 weeks. The study involves regular assessments, including clinical visits and laboratory tests, to track outcomes and safety over time.

This research aims to compare two strategies for guiding stent placement in patients with coronary artery disease fractional flow reserve FFR-guided strategy versus intravascular ultrasound IVUS-guided stent implantation after angiography-derived FFR-based decision-making. The study focuses on patients with coronary artery stenosis and evaluates whether IVUS-guided stent implantation can reduce the rate of adverse combined outcomes compared to FFR-guided percutaneous coronary intervention PCI. Participants will be divided into two groups. In the experimental group, PCI is performed if angiography-derived FFR is 0.80 or less, and stent placement is optimized using IVUS based on criteria like plaque burden and minimum stent area. In the control group, PCI is performed if FFR is 0.80 or less, with optimization guided by FFR measurements after PCI. Stenting is deferred if the FFR or angiography-derived FFR is greater than 0.80. The trial is designed to enroll about 1,942 patients, randomly assigned equally to each group, with a follow-up period extending up to 60 months. During the study, participants will be monitored and assessed for patient-oriented composite outcomes including death, heart attack, or need for further revascularization at 24 months, with additional evaluations continuing through 60 months. Researchers will also examine individual components of these outcomes, target vessel failure, cost-effectiveness, and other cardiovascular events. Safety and clinical outcomes will be tracked carefully throughout the study duration, which includes 24 months for patient enrollment and 24 months for follow-up after randomization.
