This research aims to understand how patients with cancer respond to COVID-19 vaccination by studying the levels of protective antibodies over time. The focus is on individuals with solid organ malignancies receiving various anti-cancer treatments such as chemotherapy, targeted therapy, and immunotherapy, as well as those who have been disease-free for at least six months. Since cancer patients were excluded from initial vaccine trials, this study seeks to fill knowledge gaps about vaccine safety and effectiveness in this group. Participants include cancer patients who are either undergoing active treatment or are disease-free for six months or more. They are grouped based on their treatment type chemotherapy, targeted therapy, immunotherapy, or disease-free status. The study involves monitoring antibody trends related to COVID-19 infection and vaccination at multiple time points over a 12-month period. During the study, researchers will collect blood samples to measure neutralizing and spike antibody levels every three months for up to one year. Participants will be followed to track their immune response depending on their cancer treatment and biological aging status. The study will also assess how antibody levels change over time and correlate with different treatments and patient characteristics. Safety and consent are carefully monitored throughout the trial.

This Phase 3, open-label international trial involves multiple parts, including dose confirmation, drug interaction assessments, and efficacy comparisons. The study also includes substudies focusing on drug-drug interaction potential and first-line treatment in patients with specific genetic mutations KIT exon 9. Approximately 482 patients will participate across these parts.

Researchers are evaluating the effect of involving caregivers in a rehabilitation approach called caregiver-assisted rehabilitation with strategy training CAR-ST to improve daily activity functions in adults who have had a stroke. The study aims to compare CAR-ST with strategy training alone and with an education program to see which approach leads to better improvements in activity performance and whether these improvements extend to other areas like participation and impairment. This is a single-blinded, three-arm randomized controlled trial conducted in multiple centers to assess the potential benefits of caregiver involvement in home-based post-stroke rehabilitation. Participants will be randomly assigned to one of three groups CAR-ST, strategy training alone, or an education program. The CAR-ST and strategy training groups receive up to 10 therapist-guided sessions over a maximum of 6 weeks, with sessions once or twice weekly lasting about 60 minutes each. CAR-ST involves caregivers actively assisting and motivating participants during at-home practice, while the strategy training group does not include caregiver participation. The education group receives 10 matched sessions focused on stroke information delivered through face-to-face talks, video calls, or phone calls. During the study, participants will be assessed at four time points before treatment, immediately after the intervention, and at 3- and 6-month follow-ups. Researchers will use various clinical tools to measure changes in activity performance, participation, quality of life, self-efficacy, motor function, cognition, and goal attainment. Qualitative interviews will also explore participant and caregiver experiences and satisfaction. The total involvement spans from baseline through six months after treatment, with continuous monitoring and data analysis to evaluate the interventions impact.

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 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 treatments for radiographic axial spondyloarthritis r-axSpA, a form of arthritis causing pain, stiffness, and swelling in the spine and pelvis joints. This condition shows visible damage on X-rays. The study aims to evaluate if different doses of the medicine tulisokibart can improve r-axSpA symptoms compared to a placebo, which helps measure the medicines effects accurately. Participants will be assigned to one of several groups receiving high, medium, or low doses of tulisokibart, or a placebo. The study includes a 16-week placebo-controlled phase. After that, participants receiving the low dose or placebo will be re-assigned to medium or high doses. Following this, there is a long-term extension lasting 124 weeks, which has a 40-week main extension and an 84-week optional extension, allowing continued treatment and observation. Throughout the study, participants will have regular assessments to monitor symptoms and disease activity using various indexes and imaging scores. Researchers will track the percentage of participants who achieve improvement at week 16 and monitor safety by recording adverse events up to approximately 154 weeks. The study uses injections of tulisokibart or placebo under the skin and includes ongoing evaluations of physical function, pain, inflammation, and quality of life.

Researchers are evaluating new treatments for locally advanced non-small cell lung cancer NSCLC that cannot be surgically removed and has a specific gene mutation called KRAS G12C. This trial aims to find out if the combination of calderasib MK-1084 and durvalumab can help participants live longer without their cancer growing or spreading compared to durvalumab with a placebo after they have completed chemotherapy and radiation therapy. Participants will be randomly assigned to receive either calderasib along with durvalumab or a placebo along with durvalumab. Calderasib is taken by mouth as a tablet, and durvalumab is given as an intravenous infusion. This study is double-blinded, meaning neither the participants nor the researchers know who receives the active drug or placebo. The treatment period will be followed by long-term monitoring. During the study, participants will have various assessments including survival monitoring up to approximately 9 years, evaluations of adverse events, response rates, and quality of life questionnaires. Researchers will also collect tumor tissue samples for biomarker analysis. The main measurement is progression-free survival, checked for up to about 6 years. Participants health and side effects will be closely tracked throughout and after treatment.

Researchers are evaluating the efficacy and safety of rilvegostomig compared to pembrolizumab, both combined with platinum-based doublet chemotherapy, as a first-line treatment for patients with locally advanced or metastatic non-squamous non-small cell lung cancer NSCLC whose tumors express PD-L1 at levels of 1% or higher. This Phase III, randomized, double-blind, global study aims to compare these treatments to improve outcomes for this patient group. Participants will receive either rilvegostomig or pembrolizumab, each given intravenously on Day 1 of every 21-day cycle, combined with platinum-based doublet chemotherapy either carboplatin or cisplatin also given on Day 1 of each cycle for up to four cycles. After chemotherapy cycles, patients continue with rilvegostomig or pembrolizumab monotherapy combined with pemetrexed maintenance. The study follows patients for up to approximately six years to monitor treatment effects and safety. During the study, participants undergo assessments including imaging scans to measure tumor size, blood tests to evaluate organ function, and questionnaires about symptoms and quality of life.
