Researchers are evaluating new treatments for advanced renal cell carcinoma RCC, a type of kidney cancer. This study compares the effects of combining two targeted therapies, belzutifan and zanzalintinib, against belzutifan with a placebo. The goal is to see if the combination can help people live longer and prevent the cancer from getting worse after other treatments have failed. Participants will take 120 mg of belzutifan orally and either 60 mg of zanzalintinib or a matching placebo once daily for about 24 months. The study is randomized and double-blind, meaning neither participants nor researchers know who receives the active combination or placebo. Two groups are compared belzutifan plus zanzalintinib and belzutifan plus placebo. During the study, participants will be monitored for progression-free survival and overall survival, with assessments up to around 30 to 50 months. Researchers will also evaluate tumor response, duration of response, quality of life, and side effects. Safety and tolerability will be tracked throughout treatment and follow-up periods. The study is sponsored by Merck Sharp & Dohme LLC and aims to provide important information on treating advanced RCC.

Researchers are evaluating if combining the medicines calderasib and subcutaneous pembrolizumab can more effectively treat people with non-small cell lung cancer NSCLC that has a KRAS G12C mutation. The study aims to find out whether patients receiving calderasib with pembrolizumab live longer without their cancer growing or spreading compared to those receiving pembrolizumab with chemotherapy. This is a Phase 3 clinical trial focusing on first-line treatment for advanced or metastatic nonsquamous NSCLC. Participants are assigned to one of two groups. One group receives subcutaneous pembrolizumab plus berahyaluronidase alfa every 6 weeks for up to 18 cycles about 2 years along with oral calderasib until treatment discontinuation criteria are met. The other group receives the same pembrolizumab and berahyaluronidase alfa regimen plus chemotherapy with pemetrexed and either carboplatin or cisplatin infusions during the early cycles. Treatment continues based on individual response and tolerability. During the study, participants will have regular visits for treatment and monitoring. Researchers will assess progression-free survival, overall survival, response rates, and quality of life using questionnaires and symptom scores over several years. Safety will be monitored through adverse event reporting. The trial lasts up to about 7 years with ongoing evaluation of health outcomes and side effects to understand the impact of these treatment combinations.

Researchers are studying treatments for locally advanced or metastatic colorectal cancer mCRC that cannot be removed by surgery and has a specific KRAS G12C gene mutation. This trial aims to evaluate if adding the targeted therapies calderasib and cetuximab to the standard chemotherapy regimen mFOLFOX6 can provide better outcomes compared to mFOLFOX6 with or without bevacizumab. The study focuses on the safety and tolerability of these combinations and whether they can help people live longer without their cancer growing or spreading. Participants will be assigned to one of two groups. One group will receive calderasib orally, cetuximab every two weeks, and mFOLFOX6 chemotherapy including oxaliplatin, leucovorin or levofolinate calcium, and 5-fluorouracil every two weeks. The other group will receive mFOLFOX6 chemotherapy with or without bevacizumab every two weeks, based on the investigators decision. Treatments will continue until certain stopping criteria are met. During the study, participants will be monitored for side effects and treatment tolerance, with regular assessments of cancer progression. Researchers will measure outcomes such as dose-limiting toxicities, adverse events, progression-free survival, and overall survival. Quality of life will also be evaluated through questionnaires. The study may last up to several years, with monitoring continuing for safety and effectiveness throughout the treatment period and follow-up.

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 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 new treatment options for people living with HIV-1 Human Immunodeficiency Virus Type 1 who have not been treated before. The current standard treatment, antiretroviral therapy ART, involves taking multiple medicines daily and may cause other health problems. This study aims to compare a new study ART combining two medicines, islatravir and ulonivirine, taken once a week, against the standard daily ART to see if it works as well and is safe and tolerable. Participants will receive one of several treatments for 96 weeks the study ART with islatravir and ulonivirine taken once weekly, the standard ART with bictegraviremtricitabinetenofovir alafenamide BICFTCTAF taken once daily, or combinations involving placebos matching these treatments. The study includes two phases Phase 2 which is open-label, and Phase 3 which is double-blind and randomized. During the study, participants will have regular assessments including measuring the amount of HIV-1 RNA in their blood and monitoring for adverse events and medication tolerance. Researchers will evaluate how well the treatments control the virus and affect immune cells over 24, 48, and 96 weeks. Safety monitoring will continue for about 102 weeks. The total study duration for participants is up to 96 weeks of treatment plus follow-up.

Researchers are evaluating new medicines to prevent HIV-1 Human Immunodeficiency Virus Type 1 infection. This Phase 3 clinical study aims to determine if taking the drug MK-8527 once a month can prevent HIV-1 infection as well as or better than the standard daily pre-exposure prophylaxis PrEP. The study also assesses the safety and tolerance of MK-8527 in participants. Participants are randomly assigned to one of two groups. One group receives 11 mg of MK-8527 once monthly along with a daily placebo pill matching FTCTDF. The other group receives a daily dose of FTC245 mg TDF and a monthly placebo matching MK-8527. This treatment period lasts for approximately two years, followed by an additional 28-day period where all participants receive open-label FTCTDF daily. During the study, participants will undergo regular monitoring to check for HIV-1 infection and any adverse events. Researchers will track the number of participants who acquire HIV-1, experience side effects, or stop treatment due to side effects over the two-year period. Safety and adherence assessments will be conducted to evaluate the study treatments. The total participation time includes the two-year treatment phase plus the 28-day follow-up with open-label FTCTDF.

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 investigating new treatment options for breast cancer that is hormone receptor-positive HR and human epidermal growth factor receptor 2-negative HER2-, specifically for cases that are unresectable locally advanced or metastatic. This type of breast cancer involves cancer cells that depend on hormones like estrogen or progesterone and have low HER2 protein levels. The study focuses on comparing the effects of patritumab deruxtecan against chemotherapy or trastuzumab deruxtecan in patients whose cancer has progressed despite prior treatments. Participants receive either patritumab deruxtecan through intravenous infusions every three weeks for about 13 months or a treatment chosen by their physician, which may include various chemotherapy drugs or trastuzumab deruxtecan, administered according to specific schedules for up to 13 months. The study is randomized and open-label, meaning participants are randomly assigned to one of the treatment groups, and both the patients and researchers know which treatment is given. Throughout the study, participants undergo regular assessments to monitor cancer progression and overall survival for up to approximately 85 months. Researchers evaluate tumor response, duration of response, and changes in quality of life using standardized questionnaires. Safety is carefully monitored by recording adverse events and treatment discontinuations. The goal is to understand if patritumab deruxtecan can improve outcomes compared to current treatment options.

Researchers are investigating new treatments for metastatic cervical cancer, which is cancer that has spread beyond the cervix, the lower part of the uterus. This study evaluates the safety and effectiveness of the antibody drug conjugate sacituzumab tirumotecan sac-TMT combined with pembrolizumab and bevacizumab. The goal is to find out if these treatments, given together or with some variations, help patients live longer or delay cancer progression compared to standard care. The study has two parts. In Part 1, participants receive sac-TMT, pembrolizumab, and bevacizumab together to assess safety. In Part 2, all participants first get standard induction treatment with pembrolizumab, paclitaxel, and cisplatin or carboplatin, possibly with bevacizumab. Those whose cancer does not worsen then enter maintenance treatment, where they are randomly assigned to receive either pembrolizumab alone or sac-TMT plus pembrolizumab, with optional bevacizumab. Participants are involved for up to about 20 months during maintenance treatment after up to 4 months of induction. The study monitors safety by tracking side effects and treatment discontinuations. Effectiveness is measured by progression-free survival and overall survival up to several years. Quality of life and physical functioning are also assessed through questionnaires. Treatments and evaluations occur through regular intravenous infusions and periodic monitoring visits.
