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 safety and effectiveness of KarXT combined with KarX-EC in adults aged 55 to 90 who have agitation related to Alzheimers Disease. This Phase 3, randomized, double-blind, placebo-controlled study aims to address agitation symptoms in this population by comparing the investigational drugs with a placebo. The study is sponsored by Bristol-Myers Squibb and uses established diagnostic criteria for Alzheimers Disease. Participants will receive either the combination of XanomelineTrospium Chloride capsules KarXT KarX-EC or a placebo with specified doses on designated days. The study includes a parallel group design and treatment lasts for 14 weeks. The main focus is to assess changes in agitation using the Cohen-Mansfield Agitation Inventory-International Psychogeriatric Association CMAI-IPA total score. During the study, participants will undergo regular assessments including cognitive and behavioral evaluations, safety monitoring through vital signs, laboratory tests, electrocardiograms, and rating scales for movement disorders and suicidal ideation. Caregivers will be involved to help monitor participant status and medication compliance. The primary outcome is measured at Week 14, with safety follow-up extending to Week 18. Participants are expected to be engaged throughout the treatment period and follow-up assessments.

Researchers are studying treatments for patients with hormone receptor-positive HR-positive and HER2-negative early-stage breast cancer who are at higher risk of relapse after surgery. This phase II, open-label study focuses on using a biomarker called circulating tumor DNA ctDNA to monitor minimal residual disease. The goal is to identify patients at molecular relapse and evaluate whether treatment at this stage can improve outcomes. The study involves multiple centers and is designed to test different treatment options based on ctDNA results. The study has three phases pre-screening, molecular follow-up ctDNA surveillance, and treatment. After giving consent, about 976 eligible patients will enter the ctDNA surveillance phase where tumor tissue and blood samples are collected to create a personalized mutation panel. Blood samples will be analyzed every three months during the first year and every six months thereafter to detect ctDNA. When ctDNA positivity is confirmed, up to 40 patients will be assigned sequentially to one of four treatment arms continuing standard endocrine therapy ET, giredestrant alone, giredestrant with abemaciclib, or giredestrant with inavolisib. Treatments are taken orally in cycles lasting 28 days and may continue up to five years or until disease recurrence or unacceptable side effects. Male and premenopausal participants receive additional hormone therapy LHRH agonist as needed. Participants will undergo regular blood sample collections during surveillance and treatment to monitor ctDNA levels and correlate changes with treatment response. Safety and side effects will be tracked throughout the treatment phase, which can last up to five years. After stopping treatment, patients enter a follow-up period where survival and new cancer therapies are recorded every three months. The primary outcome is measuring a decrease or clearance of ctDNA three months after starting treatment. Secondary outcomes include various ctDNA changes over time and treatment-related adverse events. Additional treatment arms may be added based on ongoing results.

Researchers are conducting a prospective, multicenter observational study to create a registry for patients with unresectable locally advanced or metastatic breast cancer. This study includes patients diagnosed from January 2016 onwards, either at first diagnosis or after recurrence. Treatment choices are made independently by physicians, and the study does not specify any treatment regimen. The study groups are defined by breast cancer subtypes based on receptor expression, including Luminal A-like, Luminal B-like HER2 negative and positive, HER2-enriched, and Triple Negative subtypes. Since this is an observational study, patients receive standard care as determined by their doctors, and no intervention is assigned by the study. Participants medical records and disease management data will be collected and reviewed over an 8-year period. Researchers will evaluate the distribution of breast cancer subtypes, patient and tumor characteristics, hereditary risk factors, gender differences in disease progression, timing of primary tumor surgery, and biomarker presence in tumor and blood samples. Patients may withdraw consent at any time, and the study aims to follow patients until death or study completion.

This research aims to evaluate the effectiveness and safety of zanidatamab combined with a physicians choice of chemotherapy compared to trastuzumab combined with chemotherapy in treating adults with metastatic HER2-positive breast cancer who have either progressed on or cannot tolerate previous trastuzumab deruxtecan T-DXd treatment. Zanidatamab has shown promising results against various HER2-positive advanced tumors, including metastatic breast cancer, and may serve as a potential treatment option for these patients. The study also investigates patient-reported tolerability and physical functioning, as well as the pharmacokinetics and immune response to zanidatamab with chemotherapy. Participants will be randomly assigned to receive either zanidatamab or trastuzumab, each given by intravenous infusion alongside one of several chemotherapy options chosen by the physician eribulin, vinorelbine, gemcitabine, or capecitabine the latter is taken orally. Treatment will be administered according to the assigned group, and the study is open-label and multicenter, designed to compare these two treatment combinations in this patient population. During the study, participants will undergo regular assessments to monitor disease progression using imaging criteria RECIST version 1.1, evaluate survival, treatment response, and duration of response. Safety and side effects will be tracked through adverse event reporting and patient questionnaires on symptoms and physical function. Blood samples will be collected to study drug levels and immune reactions. Participants will be followed until disease progression, death, or for up to approximately 44 months for key outcomes, with overall survival monitored for up to about 80 months.

Researchers are evaluating the effectiveness and safety of combining inavolisib with a cyclin-dependent kinase 4 and 6 inhibitor CDK46i and letrozole compared to placebo plus CDK46i and letrozole in adults with endocrine-sensitive PIK3CA-mutated hormone receptor-positive HR, HER2-negative advanced breast cancer. This phase III, randomized, double-blind study focuses on participants who have measurable disease and meet specific hormone receptor and HER2 status criteria. Participants are randomly assigned to receive either oral inavolisib once daily along with letrozole and CDK46i or placebo once daily with letrozole and CDK46i. The CDK46i is given on a schedule of either Days 1-21 or Days 1-28 of each 28-day cycle. The study includes parallel groups to compare these treatment combinations over time. During the study, participants will be monitored for progression-free survival, overall survival, response rates, duration of response, clinical benefit, and changes in pain, physical function, and global health status. Safety will be assessed by tracking adverse events and patient-reported treatment side effects using questionnaires. The study will follow participants for up to seven years, with regular evaluations to track disease status and quality of life.

Researchers are evaluating ART0380, a new oral drug that targets ATR kinase, in adults with advanced or metastatic solid tumors, including ovarian, peritoneal, fallopian tube, endometrial, colorectal, pancreatic, and acinar cell cancers. This open-label Phase IIIa study aims to find the recommended safe dose of ART0380 alone and combined with gemcitabine or irinotecan, understand side effects, and assess early signs of effectiveness. Participants will receive ART0380 either alone or in combination with gemcitabine or irinotecan in 21-day treatment cycles. ART0380 dosing schedules include intermittent or continuous oral administration. Gemcitabine is given on Days 1 and 8, and irinotecan is given as a 90-minute infusion on Days 1 and 8. The study has multiple parts evaluating different dosing regimens and patient groups, including dose escalation and dose expansion cohorts, with some participants randomized to receive combination therapy or gemcitabine alone. During the study, participants will undergo regular assessments including imaging scans to measure tumor response, blood tests for safety and pharmacokinetics, and tumor marker evaluations over several months. Researchers will monitor side effects from the treatments and measure outcomes such as maximum tolerated dose, progression-free survival, response rates, and overall survival. The study includes follow-up for up to 24 months to observe long-term effects.

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 studying ifinatamab deruxtecan I-DXd in adults with advanced or metastatic esophageal squamous cell carcinoma ESCC that cannot be surgically removed and who have seen their disease worsen after treatment with platinum-based chemotherapy and immune checkpoint inhibitors. The study aims to compare I-DXd with chemotherapy chosen by the investigator to evaluate overall survival and other key outcomes. Participants will be randomly assigned to receive either I-DXd given through an intravenous infusion at 12 mgkg every 21 days or one of several chemotherapy drugs docetaxel, paclitaxel, or irinotecan hydrochloride administered intravenously. The study will continue to assess these treatments throughout multiple 21-day cycles. During the trial, participants will be monitored for overall survival, progression-free survival, tumor response, and quality of life using questionnaires. Safety will be closely tracked by recording adverse events and measuring drug levels in the blood. The study may last up to approximately 54 months for each participant, with regular assessments including imaging scans and laboratory tests to follow the disease and treatment effects.

Researchers are evaluating the efficacy and safety of iza-bren, a bi-specific antibody-drug conjugate targeting EGFR and HER3 with a chemotherapy payload, compared to treatment chosen by physicians including paclitaxel, nab-paclitaxel, carboplatin plus gemcitabine, and capecitabine for patients with first-line metastatic triple-negative breast cancer TNBC or low estrogen receptor ER-low, HER2-negative breast cancer who cannot receive anti-PDL1 or endocrine therapies. This study includes adults with locally advanced, recurrent inoperable, or metastatic disease who meet specific eligibility criteria. Participants are randomly assigned to receive iza-bren or one of the physicians choice chemotherapy regimens. The treatments are given at specified doses on scheduled days. The study includes two phases Phase 2 to determine the recommended dose of iza-bren and Phase 3 to compare progression-free survival and other outcomes. The study will last several years, with follow-up extending up to approximately 47 months after randomization.
