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 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 high-risk, early-stage breast cancer, specifically targeting two types triple-negative breast cancer TNBC and hormone receptor-low positiveHER2-negative breast cancer. These cancers are characterized by low or no HER2 protein and low hormone receptor presence. The study aims to evaluate if adding sacituzumab tirumotecan sac-TMT to pembrolizumab and chemotherapy can better reduce cancer cells in tumors and lymph nodes and improve the length of time patients live without cancer progression compared to pembrolizumab with chemotherapy alone. Participants in this trial receive one of two treatment plans. One group gets sacituzumab tirumotecan intravenously every two weeks plus pembrolizumab every three weeks for 12 weeks, followed by pembrolizumab with carboplatin and paclitaxel for another 12 weeks. After 3 to 6 weeks, surgery and optional radiation therapy take place, followed by pembrolizumab for about 28 weeks. Participants with remaining disease may receive additional treatments chosen by their doctors, including olaparib, capecitabine, doxorubicin, epirubicin, or cyclophosphamide. The other group receives chemotherapy drugs carboplatin and paclitaxel with pembrolizumab initially, then pembrolizumab with cyclophosphamide and doxorubicin or epirubicin, followed by surgery, optional radiation, and pembrolizumab for about 28 weeks, with similar additional options for residual disease. During the study, participants undergo core needle biopsies, receive intravenous infusions of study drugs, and have surgery and possible radiation therapy. Researchers assess outcomes such as the percentage of participants with no detectable cancer cells at surgery pathological complete response, event-free survival up to about 92 months, and overall survival up to nearly 10 years. Quality of life and side effects are monitored through questionnaires and adverse event tracking. The study lasts several years, with various assessments throughout treatment and follow-up periods to gather comprehensive data on treatment effects and safety.

Researchers are studying people with idiopathic pulmonary fibrosis IPF or progressive pulmonary fibrosis PPF who have previously taken nerandomilast in another study. The aim is to assess how well patients tolerate long-term treatment with nerandomilast and to evaluate whether it improves lung function and delays worsening symptoms, hospital visits, or death. This open-label extension trial is sponsored by Boehringer Ingelheim and focuses on treatment over an extended period. Participants take nerandomilast tablets for up to 1 year and 10 months while continuing their usual pulmonary fibrosis treatments. The study involves a single treatment group receiving the drug, and no placebo or comparison groups. Regular visits with doctors help monitor health and collect data during this extended treatment phase. Throughout the study, participants undergo regular lung function tests and health assessments to track any adverse events and changes in lung capacity. The main outcome measured is the occurrence of any adverse events for up to about 99 weeks. Secondary outcomes include changes in forced vital capacity and time to worsening of disease symptoms or hospitalization. The study includes ongoing safety monitoring with a total participation time of up to nearly two years.

Researchers are evaluating nemtabrutinib compared with investigators choice of ibrutinib or acalabrutinib in adults with untreated chronic lymphocytic leukemia CLL or small lymphocytic lymphoma SLL. The study aims to assess whether nemtabrutinib is not worse than these comparators in terms of objective response rate and whether it can provide longer progression-free survival. This is a Phase 3 randomized clinical trial sponsored by Merck Sharp & Dohme LLC. Participants will receive either nemtabrutinib, ibrutinib, or acalabrutinib orally at specified doses until their disease progresses, unacceptable side effects occur, or other discontinuation criteria are met. The trial uses a parallel-group design where participants are randomly assigned to one of the treatment groups, and no masking is involved. Both treatment arms continue until progression or intolerance. During the study, participants will be monitored regularly up to about 33 months for response rate and up to about 104 months for progression-free survival and overall survival. Assessments include clinical evaluations, safety monitoring for adverse events, and duration of response measurements. The study tracks treatment tolerability, discontinuations due to adverse events, and overall outcomes to better understand the therapies effects in this patient population.

Researchers are evaluating the efficacy and safety of opevesostat combined with daily corticosteroids compared to alternative treatments abiraterone acetate or enzalutamide in participants with metastatic castration-resistant prostate cancer mCRPC who have previously been treated with one next-generation hormonal agent NHA. The study aims to determine if opevesostat offers better control of disease progression assessed by radiographic progression-free survival, including participants with and without androgen receptor ligand binding domain mutations. Overall survival has also been included as a secondary outcome measure. Participants are randomly assigned to one of two groups. One group receives opevesostat 5 mg orally twice daily, plus dexamethasone 1.5 mg and fludrocortisone acetate 0.1 mg orally once daily, continuing until disease progression. Hydrocortisone is available as a rescue medication if needed. The other group receives either abiraterone 1000 mg once daily with prednisone 5 mg twice daily or enzalutamide 160 mg once daily, also until disease progression. This open-label, phase 3 study compares these two treatment approaches in a parallel design. During the study, participants undergo regular assessments including imaging scans to measure disease progression, safety monitoring, and evaluations of overall survival and quality of life. Researchers track radiographic progression-free survival for up to 52 months and secondary outcomes such as overall survival, time to new treatments, pain progression, and prostate-specific antigen PSA responses for up to approximately 82 months. Participants are closely monitored for adverse events and treatment tolerability throughout the study duration, which spans several years.

Researchers are investigating whether adding intismeran autogene to pembrolizumab after surgery helps people with non-small cell lung cancer NSCLC stay cancer-free longer compared to pembrolizumab with a placebo. This study focuses on participants whose tumors did not fully respond to treatment before surgery. It is a phase 3 trial aiming to evaluate treatment options for resectable stage II to IIIB N2 NSCLC patients who did not achieve a complete pathological response after neoadjuvant therapy. Participants receive neoadjuvant treatment with pembrolizumab and chemotherapy drugs such as cisplatin, carboplatin, pemetrexed, gemcitabine, or paclitaxel, given by intravenous infusion every three weeks for up to four cycles. After surgery, participants receive adjuvant treatment with pembrolizumab every six weeks combined with either intismeran autogene or placebo by intramuscular injection every three weeks, for up to seven and nine doses respectively. During the study, participants undergo treatment cycles, surgery, and follow-up assessments. Researchers evaluate disease-free survival over approximately 97 months and monitor overall survival, metastasis-free survival, quality of life, physical and role functioning, and adverse events up to around 129 months. The study includes regular evaluations and safety monitoring to understand the impact of these treatments on long-term outcomes and participant well-being.

Researchers are conducting a Phase III, randomized, open-label multicenter study to evaluate the effectiveness and safety of giredestrant compared with fulvestrant. Both drugs are combined with the investigators choice of a CDK46 inhibitor palbociclib, ribociclib, or abemaciclib in participants with estrogen receptor-positive ER, HER2-negative advanced breast cancer who have become resistant to prior adjuvant endocrine therapy. Participants will be randomly assigned to one of two groups one group will receive giredestrant 30 mg orally daily on Days 1-28 of each 28-day cycle, while the other will receive fulvestrant 500 mg intramuscularly on Days 1 and 15 of Cycle 1 and Day 1 of subsequent 28-day cycles. Both groups will also receive a CDK46 inhibitor chosen by the investigator, with dosing schedules depending on the specific inhibitor selected. Preperimenopausal women and men will receive a luteinizing hormone-releasing hormone LHRH agonist during treatment. Participants will be assessed for progression-free survival over up to 5 years, with additional measures including overall survival, response rates, duration of response, clinical benefit, and quality of life. Safety will be monitored through adverse event reporting, vital signs, and laboratory tests during treatment and up to 28 days after the last dose. The study is led by Hoffmann-La Roche and aims to provide detailed information on the treatments effects in this patient population.

Researchers are evaluating the safety, immune response, and effectiveness of the V181 dengue vaccine in healthy children aged 2 to 17 years. This study aims to see if V181 can reduce the number of dengue infections caused by any of the four dengue virus types, regardless of whether participants have had dengue before. The trial is a phase 3, randomized, double-blind, placebo-controlled study sponsored by Merck Sharp & Dohme LLC. Participants will be randomly assigned to receive a single 0.5 mL dose of either the V181 vaccine or a placebo by subcutaneous injection on Day 1. About 3600 participants are included in the Reactogenicity and Immunogenicity Subset, which will be monitored for safety and immune response for 28 days after vaccination. A smaller group of about 620 participants from this subset will be followed for up to 5 years to assess long-term immune response using specific virus neutralization tests. During the study, participants will be monitored for adverse events, vaccine reactions, and dengue infections, including severity and hospitalization rates, up to 5 years after vaccination. Safety assessments include tracking medically attended and serious adverse events. Immune responses will be measured by antibody levels and seroconversion rates. Participants will have scheduled visits during the first month postvaccination and ongoing follow-ups for several years to evaluate the vaccines long-term effects and protective benefits.

Researchers are evaluating whether adding zilovertamab vedotin to a standard treatment regimen can help people with previously untreated diffuse large B-cell lymphoma DLBCL live longer without the cancer growing or spreading. This phase 3 randomized study compares the combination of zilovertamab vedotin with rituximab plus cyclophosphamide, doxorubicin, and prednisone R-CHP against the standard regimen of rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone R-CHOP. The trial is sponsored by Merck Sharp & Dohme LLC and aims to improve treatment outcomes for people with this type of lymphoma. Participants receive treatment in cycles lasting 21 days, for up to 6 cycles approximately 4 months. One group receives zilovertamab vedotin plus rituximab or a rituximab biosimilar, cyclophosphamide, doxorubicin, and prednisone or prednisolone or methylprednisolone, while the comparison group receives rituximab or biosimilar, cyclophosphamide, doxorubicin, vincristine, and prednisone or prednisolone or methylprednisolone. Both groups may receive 2 additional cycles of rituximab or biosimilar if they have high-risk DLBCL. All infusions are given intravenously on Day 1 of each cycle, with prednisone or similar drugs taken orally on Days 1-5 of each cycle. Throughout the study, participants are closely monitored for progression-free survival up to about 50 months, as well as other outcomes such as overall survival, response to treatment, adverse events, and quality of life changes. Assessments include clinical evaluations during treatment and follow-up periods, with safety monitoring continuing for up to 9 months. This comprehensive follow-up helps researchers understand the effects and tolerability of the treatments over time.
