Researchers are investigating new treatments for people with high-risk, early-stage breast cancer, specifically targeting triple-negative breast cancer (TNBC) and hormone receptor (HR)-low positive/HER2-negative breast cancer. These types have little or no HER2 protein and involve hormones like estrogen or progesterone. The study aims to evaluate if the addition of sacituzumab tirumotecan (sac-TMT), a targeted therapy, combined with pembrolizumab and chemotherapy can improve outcomes compared to pembrolizumab with chemotherapy alone. Participants receive treatments including sacituzumab tirumotecan, pembrolizumab, and chemotherapy drugs such as carboplatin and paclitaxel, all given by intravenous infusion. Rescue medications like antihistamines, acetaminophen, dexamethasone, or steroid mouthwash may be used as needed. The study is randomized and open-label, comparing sac-TMT followed by chemotherapy plus pembrolizumab to chemotherapy and pembrolizumab without sac-TMT. During the study, researchers will monitor participants up to about 30 weeks to assess the percentage of people with no remaining cancer cells at surgery. They will also follow participants for up to approximately 92 months to track event-free survival, meaning time without cancer growth, spread, or return. Participants will undergo imaging, clinical assessments, and laboratory tests to evaluate treatment effects and safety throughout the study.

Researchers are evaluating the efficacy and safety of rilvegostomig compared to pembrolizumab as first-line treatments for patients with metastatic non-small cell lung cancer (mNSCLC) whose tumors have high PD-L1 expression. This Phase III, randomized, double-blind, and global study focuses on participants with stage IV mNSCLC who do not have certain genetic mutations or rearrangements and are eligible for systemic therapy. Participants receive either rilvegostomig or pembrolizumab intravenously on Day 1 of each 21-day cycle. The study compares these two biological treatments given as monotherapy. Both groups will be monitored over time to assess treatment impact and safety. Throughout the study, participants undergo evaluations including tumor measurements by CT or MRI, performance status assessments, and organ function tests. Researchers will measure overall survival and progression-free survival for up to approximately five years. Tumor samples are collected before treatment for central testing, and participants’ health and treatment responses are closely followed during the trial period.

This research aims to verify the accuracy, stability, and clinical usefulness of artificial intelligence (AI) algorithms for measuring heart function through echocardiography. The study involves collaboration with multiple medical centers and focuses on comparing AI measurements with those done manually by physicians of different experience levels. It also explores whether AI can reduce the time needed for echocardiogram analysis and improve clinical workflows, while assessing AI's performance in complex heart conditions such as cardiomyopathy and valve disease. The study collects echocardiographic data using Mindray ultrasonic machines, with AI and physicians at each center measuring key heart parameters including left and right ventricular size and function. AI and intermediate doctors complete measurements within one day of data collection, while senior physicians at the main research unit finalize their assessments within one month. The goal is to establish a standardized reference system for AI in ultrasound measurement and promote its use across various medical institutions. Participants aged 18 to 80 years with specific heart conditions or normal hearts are involved. Researchers measure heart chamber sizes and functions through echocardiography, comparing AI and physician results for consistency and accuracy. The study also monitors how AI-assisted measurements could optimize diagnosis time and medical resource use. The total duration of participant involvement depends on data collection and measurement timelines, with ongoing analysis to support AI's clinical application in cardiovascular care.

Researchers are evaluating the safety and effects of fosmanogepix, a study medicine, for treating candidemia and invasive candidiasis, which are serious fungal infections caused by Candida species. This Phase 3 clinical trial compares fosmanogepix to the standard treatment of caspofungin followed by fluconazole, aiming to show that fosmanogepix is not worse than the standard therapy by a margin of 15%. The study includes adult patients diagnosed with these infections. Participants will receive either fosmanogepix or caspofungin as an intravenous infusion daily at the study clinic. After the initial infusion phase, patients may switch to oral tablets of fosmanogepix or fluconazole capsules, which can be taken at the clinic or at home if discharged. Treatment duration varies by individual, lasting up to six weeks depending on infection clearance and symptom improvement. A follow-up visit will take place six weeks after stopping treatment. During the study, patients will undergo multiple visits to monitor their health and treatment response. Researchers will assess outcomes such as the proportion of patients alive at 30 days and the overall treatment success at the end of study treatment, up to day 42. Safety will be closely monitored throughout the study and during follow-up, ensuring comprehensive evaluation of the treatments over the entire participation period.

Researchers are evaluating the safety and early effectiveness of AL8326 tablets combined with Toripalimab in patients with advanced recurrent or metastatic solid tumors. This open, non-randomized Phase I/IIa clinical trial focuses on patients who have failed standard therapies or for whom no effective treatment is available, including those receiving Toripalimab as a second-line or later treatment. The study aims to determine the recommended dose and assess tumor response over time. Participants will receive AL8326 tablets orally once daily at a dose of 10 mg per tablet, alongside Toripalimab administered by injection every 21 days at 240 mg per cycle. The trial includes a Phase I portion to identify the recommended dose after the first 28-day cycle, followed by a Phase IIa segment that monitors objective remission rates every 2 to 4 cycles, continuing for up to 24 months. Treatment schedules and dosages are carefully managed to evaluate combined therapy effects. During the study, participants will undergo regular medical assessments, including tumor measurements using RECIST 1.1 criteria and safety evaluations such as blood tests, heart function tests, and monitoring of side effects. Researchers will track the participants' response to treatment, life expectancy, organ function, and overall health status. Follow-up procedures ensure safety and effectiveness are continually monitored throughout the treatment period and beyond.

This trial evaluates the effectiveness and safety of the GR2001 injection compared to Human Tetanus Immunoglobulin (HTIG) for preventing tetanus. It is a Phase III study focused on patients suspected of tetanus exposure through dirty or contaminated wounds. The study aims to assess the immunogenicity and pharmacokinetics of GR2001 as a potential alternative to HTIG. Participants will receive either the GR2001 injection or HTIG on the first day of the study. GR2001 is provided in a 5mg/1ml vial packaged with specialized materials to ensure safety and stability. HTIG is a licensed human tetanus immunoglobulin derived from human plasma and prepared in injectable form. Both treatments are administered once for tetanus prophylaxis. During the study, researchers will measure the increase in anti-tetanus antibody levels up to 12 hours after treatment to evaluate immune response. Participants must provide informed consent and will be monitored for safety and any adverse reactions. The study includes adults aged 18 and older with suspected tetanus exposure, and the overall participation involves initial treatment and short-term antibody measurement for effectiveness.

Researchers are evaluating AZD0780, an oral PCSK9 inhibitor, in a phase 3, randomized, placebo-controlled study to see if it can reduce the risk of major adverse cardiovascular events (MACE-PLUS) in adults with established atherosclerotic cardiovascular disease (ASCVD) or those at high risk for a first ASCVD event. The study compares AZD0780 to a placebo and monitors participants from randomization until the primary analysis censoring date, followed by a final study closure visit. Participants will be randomly assigned to receive either oral AZD0780 or an oral placebo once daily. The treatment period lasts until the primary analysis censoring date, after which a study closure visit will occur. The study is event-driven and designed to assess the time to the first major cardiovascular event during treatment. During the study, participants will be closely monitored with various assessments to evaluate cardiovascular outcomes and safety over approximately 54 months. Researchers will track the time to first event of any component of MACE-PLUS and collect data to assess the effect of AZD0780 compared to placebo. The study includes regular visits and evaluations to ensure participant safety and adherence to treatment.

Researchers are evaluating the safety and effectiveness of HLX22 combined with trastuzumab and chemotherapy as the first treatment for patients with HER2-positive locally advanced or metastatic adenocarcinoma of the gastric or gastroesophageal junction. This phase 2, double-blind, randomized, and multiregional study compares this combination against trastuzumab and chemotherapy with or without pembrolizumab. The study aims to measure how well the treatments work in controlling the disease and improving survival for up to five years. Participants will be randomly assigned to one of two groups. One group receives HLX22 at 15 mg/kg every three weeks along with trastuzumab, chemotherapy (XELOX regimen), and possibly a placebo for pembrolizumab. The other group receives a placebo for HLX22 plus trastuzumab, chemotherapy (XELOX), and possibly pembrolizumab every three weeks. Treatment continues until the disease worsens, unacceptable side effects occur, withdrawal of consent, or other protocol-specified reasons. Throughout the study, participants will undergo regular assessments including tumor scans reviewed by an independent committee to evaluate progression-free survival and overall survival over up to five years. Other evaluations include safety monitoring and organ function tests. The study tracks how long patients live without disease progression and overall survival, aiming to better understand the benefits and risks of HLX22 combined with current standard treatments.

Researchers are conducting a Phase 3 study to compare two front-line treatments for adults with nonsquamous non-small cell lung cancer (NSCLC) that is stage IV or advanced stage IIIB/C. The study focuses on patients whose tumors have a KRAS p.G12C mutation and are negative for PD-L1 expression. The main goal is to evaluate how each treatment affects progression-free survival and overall survival over about 2.5 years. Participants will be randomly assigned to receive either sotorasib combined with platinum doublet chemotherapy or pembrolizumab combined with platinum doublet chemotherapy. Sotorasib is given orally, while pembrolizumab is given intravenously. Both groups will receive the combination therapies as their initial treatment for advanced NSCLC. During the study, participants will be monitored regularly to assess treatment effects and safety. Researchers will track how long patients live without the cancer worsening and overall survival over approximately 2.5 years. The study includes evaluations to determine eligibility and ongoing assessments to monitor health and treatment response throughout the trial period.

Researchers are evaluating the effect of a triple therapy inhaler called BGF MDI containing budesonide, glycopyrronium, and formoterol fumarate compared with a dual therapy inhaler called GFF MDI containing glycopyrronium and formoterol fumarate in people with Chronic Obstructive Pulmonary Disease (COPD) who have a higher risk of heart and lung problems. This Phase III randomized, double-blind, parallel group study takes place at multiple centers and focuses on cardiopulmonary outcomes in these patients. Participants receive either the BGF MDI 320/14.4/9.6 micrograms twice daily or the GFF MDI 14.4/9.6 micrograms twice daily. The treatments are inhaled using metered dose inhalers. The study compares these two therapies over time to see how they affect the time until the first severe heart or lung event occurs. The study design ensures that neither participants nor researchers know which treatment is given to reduce bias. During the study, participants will have regular visits to the study site or virtual visits to complete assessments. Researchers will monitor lung function, symptoms, and blood tests, including blood eosinophil counts and COPD assessment test scores. The main outcome measured is the time to the first severe cardiac or COPD event, with follow-up lasting up to three years. Safety and adherence to treatment will also be closely observed throughout the study period.
