Researchers are studying new treatment options for people with high-risk non-muscle invasive bladder cancer HR NMIBC, including cases with carcinoma in situ CIS. HR NMIBC affects the lining of the bladder but has not spread to muscle or beyond. The study aims to learn if adding intismeran autogene V940 to the standard Bacillus Calmette-Guerin BCG immunotherapy can improve outcomes by helping the immune system attack the cancer more effectively. Participants are divided into groups receiving different treatments. One group Cohort A receives both intismeran autogene via intramuscular injection every 3 weeks for 9 doses and BCG instillations weekly in specific weeks over about 75 weeks. Another group receives only BCG following the same weekly schedule. A third group Cohort B receives intismeran autogene alone every 3 weeks for 9 doses. The study evaluates these treatments over several years. During the study, participants will have regular treatments and follow-up visits where researchers will monitor cancer progression, recurrence, and survival for up to approximately 5 years. Assessments include event-free survival, recurrence-free survival, overall survival, response rates, time to cystectomy, and safety outcomes such as adverse events and treatment discontinuation. The study is randomized and open-label, with detailed long-term monitoring planned.

Researchers are evaluating molnupiravir, an oral medicine designed to stop the COVID-19 virus from multiplying, to see if it can prevent severe illness from COVID-19 in people at high risk of disease progression. The study focuses on adults with confirmed COVID-19 infection who are at increased risk due to age, medical conditions, or other factors. This is a Phase 3 randomized, placebo-controlled, double-blind clinical trial led by Merck Sharp & Dohme LLC. Participants will be randomly assigned to receive either molnupiravir or a matching placebo. Those in the molnupiravir group will take 800 mg orally every 12 hours for 5 days, totaling 10 doses. The same dosing schedule applies to the placebo group. Some participants may also receive remdesivir as part of standard care if clinically appropriate. During the study, participants will be monitored for up to 29 days to assess outcomes such as hospitalization, death, or medically attended visits related to COVID-19. Safety will be evaluated by tracking adverse events and discontinuation due to side effects. Researchers will also measure symptom relief, viral RNA levels, and other health indicators. The study is expected to continue until January 2031.

Researchers are evaluating the efficacy and safety of rilvegostomig compared to pembrolizumab monotherapy as the first-line treatment for patients with metastatic non-small cell lung cancer mNSCLC whose tumors express high levels of PD-L1. This Phase III, randomized, double-blind, multicenter global study focuses on patients with mNSCLC without certain genetic mutations who are suitable for this treatment approach. Participants are randomly assigned to receive either rilvegostomig or pembrolizumab intravenously on Day 1 of each 21-day cycle. The study compares these two drugs over repeated treatment cycles as first-line therapy. Both treatments are biological agents given by infusion, and the study is designed to monitor their effects over up to approximately five years. During the trial, participants will undergo regular assessments including physical exams, imaging scans such as CT or MRI to measure tumor lesions, and laboratory tests to evaluate organ function. Researchers will closely monitor overall survival, progression-free survival, treatment response, duration of response, and patient-reported outcomes on physical functioning and quality of life. Safety and immunogenicity of rilvegostomig will also be evaluated. Participants are followed and assessed for up to five years to gather comprehensive data on treatment effects and long-term outcomes.

Researchers are evaluating the safety and effectiveness of rilvegostomig combined with platinum-based chemotherapy compared to pembrolizumab combined with platinum-based chemotherapy as a first treatment for patients with locally advanced or metastatic squamous non-small cell lung cancer mNSCLC whose tumors express programmed death-ligand 1 PD-L1. This Phase III global study focuses on patients with PD-L1 tumor cell expression of 1% or higher and aims to determine which treatment provides better overall and progression-free survival. Participants will be randomly assigned to one of two study groups one group will receive rilvegostomig plus carboplatin and either paclitaxel or nab-paclitaxel chemotherapy, while the other group will receive pembrolizumab plus the same chemotherapy options. Rilvegostomig and pembrolizumab are both given intravenously on Day 1 of each 21-day cycle, with chemotherapy given up to 4 cycles. Nab-paclitaxel may be administered on Days 1, 8, and 15 of each cycle. Treatment continues with rilvegostomig or pembrolizumab until disease progression or other criteria are met. During the study, participants will undergo regular assessments including imaging scans to measure tumor response, laboratory tests to monitor organ function, and patient questionnaires about physical function and quality of life. Researchers will track overall survival, progression-free survival, response rates, and duration of response for up to approximately 6 years. Safety and immune response to rilvegostomig will also be evaluated. Participants will be closely monitored throughout the treatment and follow-up periods.

Researchers are evaluating pocenbrodib alone and in combination with darolutamide for treating metastatic castration-resistant prostate cancer mCRPC in patients who have progressed after prior therapies including anti-androgen treatments. This Phase 1b2a open-label study aims to confirm safety, pharmacokinetics, pharmacodynamics, and preliminary antitumor effects of these treatments. It includes dose escalation, optimization, and dose expansion phases to find appropriate dosing levels and assess treatment effects in patients who have also received lutetium-Lu-177-vipivotide-tetraxetan PLUVICTO prior to taxane-based therapy. The study has two main phases Phase 1b involves dose escalation with three arms exploring different dosing schedules of pocenbrodib alone or combined with darolutamide to find the maximum tolerated dose and recommended Phase 2 doses. Phase 2a expands the study with two cohorts receiving different recommended doses of pocenbrodib combined with darolutamide. Treatments are given orally with varying dosing schedules including daily and twice-daily regimens, and safety is closely monitored throughout. Participants undergo regular assessments including safety evaluations, pharmacokinetic sampling during treatment cycles each 28 days, and tumor response evaluations. The primary outcomes focus on safety, tolerability, and efficacy measures such as radiographic progression-free survival and prostate-specific antigen changes. The study lasts through the treatment duration, estimated to be around six months for Phase 2a, with ongoing safety monitoring and data collection to understand drug behavior and patient response.

Researchers are evaluating zanidatamab combined with chemotherapy for treating people with HER2-positive, early-stage breast cancer. This phase 2 study aims to assess the safety and effectiveness of this combination compared to standard treatments in participants with newly diagnosed stage II or III invasive breast carcinoma. Participants are randomly assigned to one of three treatment groups zanidatamab with paclitaxel, zanidatamab with docetaxel and carboplatin, or trastuzumab and pertuzumab with docetaxel and carboplatin. All study drugs are administered intravenously. After neoadjuvant therapy, participants will undergo either mastectomy or breast conserving surgery as decided by their physician. During the study, participants will have their response to treatment assessed through measurements such as pathologic complete response and residual cancer burden classification up to 8 months. Safety is monitored by tracking treatment-related adverse events up to 23 months. Other assessments include survival outcomes up to 46 months and serum concentrations of zanidatamab. The study participation may last several years to capture these outcomes.

Researchers are conducting a multicenter, randomized, double-blind, parallel-controlled phase I clinical study to compare HLX17 and US-sourced Keytruda in patients with resected non-small cell lung cancer, melanoma, or renal cell carcinoma. The study aims to evaluate how similar the pharmacokinetic profiles, efficacy, safety, and immune responses are between these two treatments in this patient population. Participants will receive either HLX17 or US-sourced Keytruda. Those in the HLX17 group will get 200 mg on Day 1 of every 3-week cycle for up to 12 months or until disease recurrence, death, new anti-tumor therapy, unacceptable toxicity, consent withdrawal, or study end. The Keytruda group will receive 200 mg every 3 weeks for 8 cycles 24 weeks, then switch to HLX17 on the same schedule until 12 months or similar conditions occur. During the study, participants will undergo various assessments including pharmacokinetic measurements such as drug concentration over time and at steady state, disease-free survival evaluation for up to 12 months, and monitoring for adverse events and laboratory abnormalities for up to 15 months. Safety follow-up includes vital signs, physical exams, ECGs, and immunogenicity evaluation. The total study duration includes treatment and safety monitoring phases.

Researchers are evaluating the combination of baxdrostat and dapagliflozin in people with chronic kidney disease CKD and high blood pressure hypertension. This Phase III, double-blind, placebo-controlled study aims to assess whether this combination reduces the risk of serious kidney damage, heart failure events, or cardiovascular death compared to dapagliflozin alone. The study includes participants with CKD and hypertension who meet specific kidney function and blood pressure criteria. Participants who are not already taking SGLT2 inhibitors will first complete a 4-week dapagliflozin run-in period. Then, they will be randomly assigned to receive either baxdrostat plus dapagliflozin or a placebo plus dapagliflozin. Baxdrostat dosing may start low and be increased if needed. Study visits will occur at 2, 4, 8, 16, 34, and 52 weeks after randomization, and then approximately every four months until the study ends, which is based on the number of key kidney or heart-related events. Throughout the study, participants will have regular assessments including blood tests to monitor kidney function and potassium levels, blood pressure measurements, and evaluations of heart and kidney health. If participants stop the blinded study drug early, they will continue dapagliflozin if possible and remain in the study for ongoing visits and monitoring. The main outcome is whether the combination treatment reduces the risk of a 50% sustained decline in kidney function, kidney failure, heart failure events, or cardiovascular death over up to 37 months.

Researchers are evaluating the effectiveness, safety, and tolerability of elecoglipron alone or combined with dapagliflozin compared with a placebo in adults with type 2 diabetes mellitus T2DM who are not adequately controlled by lifestyle management alone or who are on other background glucose-lowering medications. This Phase III study aims to understand how these treatments impact blood sugar control and related health factors. Participants will be randomly assigned to one of four groups elecoglipron at dose level 1 with dapagliflozin-matched placebo, elecoglipron at dose level 2 with dapagliflozin-matched placebo, a combination of elecoglipron at one of the studied doses with dapagliflozin, or matching placebos for both drugs. All treatments are taken orally once daily. The study uses a quadruple-blind design to compare these options over a treatment period lasting up to 40 weeks. During the study, participants will have their blood sugar levels measured by changes in Hemoglobin A1c HbA1c from baseline to week 40. Other assessments include body weight, blood pressure, and the time to start any additional rescue medication. Participants will attend regular visits for monitoring and safety evaluations throughout the study duration, which extends until the primary completion date in July 2028.

Researchers are evaluating HLX22 combined with trastuzumab and chemotherapy as a first-line treatment for patients with HER2-positive locally advanced or metastatic adenocarcinoma of the gastric or gastroesophageal junction. This phase 3, randomized, double-blind study compares this combination against trastuzumab plus chemotherapy with or without pembrolizumab. The trial aims to assess the efficacy and safety of adding HLX22 in this patient population. Participants will be randomly assigned in a 11 ratio to either the experimental group receiving HLX22 15 mgkg plus trastuzumab and chemotherapy XELOX with or without a placebo for pembrolizumab every three weeks, or the control group receiving placebo for HLX22 plus trastuzumab and chemotherapy XELOX with or without pembrolizumab also every three weeks. Treatment continues until clinical benefit is lost, intolerable side effects occur, death, withdrawal, or other protocol-specified reasons. Throughout the study, participants will have their disease progression monitored by an independent radiology review committee using RECIST v1.1 criteria for up to five years, along with overall survival and response rates. Safety will be regularly assessed by tracking adverse events. The study includes multiple assessments to evaluate treatment effects, and participants will be followed for long-term outcomes during the trial period.
