This trial evaluates the effectiveness of adjuvant cemiplimab immunotherapy in adults with surgically removed stage II-IIIA non-small cell lung cancer NSCLC who have not previously received adjuvant platinum-based chemotherapy. The study aims to compare disease-free survival between patients treated with cemiplimab and those under observation without additional treatment, focusing on patients with tumors showing PD-L1 expression of 1% or higher. Participants are randomly assigned to receive either cemiplimab or observation. Those in the cemiplimab group receive 350 mg intravenously every 3 weeks for 4 cycles, followed by 700 mg every 6 weeks for up to 6 cycles or until disease relapse or unacceptable side effects occur. The observation group does not receive adjuvant treatment. Treatment continues until relapse, toxicity, or completion of planned cycles. During the trial, participants undergo regular assessments including imaging and laboratory tests to monitor disease status and side effects. The main outcome measured is disease-free survival, tracked for approximately 59 months from randomization. Secondary outcomes include overall survival and the nature and severity of adverse events. Participants are monitored for safety and treatment response throughout the study period, which is expected to conclude in March 2029.

Researchers are evaluating elacestrant compared to standard endocrine therapies in adults with node-positive, Estrogen Receptor-positive ER, HER2-negative early breast cancer who are at high risk of cancer returning. The study focuses on those who have had prior endocrine therapy and aims to measure how well elacestrant may prevent invasive breast cancer recurrence over five years. Participants are randomly assigned to receive either 345 mg of elacestrant daily for five years or continue their prior standard endocrine therapy, which may include an aromatase inhibitor anastrozole, letrozole, or exemestane or tamoxifen. The trial is open-label, meaning both participants and researchers know which treatment is given. During the study, participants will have regular assessments to monitor cancer recurrence, survival, side effects, and quality of life. Evaluations include questionnaires on health status and physical functioning at baseline, six months, and annually for up to five years. Safety is tracked through adverse event reporting up to five years plus 28 days. The total participation duration can last up to five years with ongoing monitoring and data collection.

This Phase 3 treatment study includes participants with locally advanced or metastatic NSCLC and aims to compare this combination against standard care. The study is sponsored by Eli Lilly and Company and could last up to 3 years depending on individual response and disease progression. Participants receive LY3537982 orally combined with pembrolizumab given intravenously in 21-day cycles. Some groups also receive chemotherapy drugs pemetrexed and platinum cisplatin or carboplatin intravenously. There are different dose levels and combinations being tested, including placebo groups for comparison. Treatment continues until specific discontinuation criteria are met. Parts of the study are randomized and double-blinded, with some parts non-randomized for safety lead-in. During the study, participants have regular assessments including imaging scans to measure tumor response, blood tests, and questionnaires about symptoms and quality of life. Researchers monitor side effects and survival outcomes. The main measures include progression-free survival and treatment-emergent adverse events over about one year, with overall survival followed for up to three years. Participants are closely followed throughout treatment and after to evaluate the effects and safety of the study medications.

This research aims to observe the real-life effectiveness, safety, and patient-reported outcomes of standard antimyeloma treatments in adults with previously treated relapsed andor refractory multiple myeloma over a 24-month period. The study focuses on participants receiving routine care for this condition as part of their regular medical treatment. Participants with relapsed or refractory multiple myeloma undergoing standard antimyeloma treatments in routine clinical practice will be observed. There is no investigational treatment administered by the study instead, medical records will be the primary data source to track treatments and outcomes during the study. During the study, participants medical records will be reviewed to assess response rates, survival, disease progression, quality of life, and adverse events over up to 52 months. Patient health and well-being will be monitored using standardized questionnaires, and safety will be evaluated through reported side effects. The overall involvement includes observation and data collection without changing the participants treatment plans.

Researchers are evaluating the effectiveness and safety of a combination treatment including BMS-986489 a fixed dose combination of BMS-986012 and Nivolumab with Carboplatin plus Etoposide compared to Atezolizumab combined with Carboplatin plus Etoposide as a first-line therapy for participants with extensive-stage small cell lung cancer. This is a randomized, double-blind, multicenter phase 3 trial sponsored by Bristol-Myers Squibb. Participants will receive either the experimental combination of BMS-986489 with Carboplatin and Etoposide or the comparator regimen of Atezolizumab with Carboplatin and Etoposide. Doses are given on specified days according to the study protocol. The study examines these treatments as initial therapy for this type of lung cancer. During the trial, participants will be closely monitored for overall survival over a period of up to 5 years. Researchers will also measure other outcomes such as time to clinical decline based on lung cancer symptom scores, response duration, progression-free survival, and the occurrence of adverse events up to 135 days after the last treatment. Regular assessments will include imaging and clinical evaluations to track treatment effects and safety throughout the study.

Researchers are conducting an international, multicenter, open-label phase III trial to evaluate the addition of adjuvant durvalumab after neoadjuvant chemotherapy combined with durvalumab and surgery in patients with early-stage, operable non-small cell lung cancer NSCLC stages IIB to IIIB. The main goal is to see if giving durvalumab after surgery improves disease-free survival in patients who do not achieve complete pathological response after initial treatment. The treatment plan involves 3 to 4 cycles of neoadjuvant durvalumab combined with platinum-based doublet chemotherapy, followed by surgery to remove the tumor. After surgery, patients with complete R0 or microscopic residual R1 resection are randomly assigned to either receive adjuvant durvalumab given intravenously at 1500 mg every 4 weeks for up to 12 cycles or to be observed without additional treatment. Participants will be monitored regularly for about 60 months after randomization to assess disease-free survival and other outcomes such as overall survival, time to recurrence, and treatment toxicity. Assessments include imaging scans to check for metastatic disease, pathological review after surgery, and ongoing safety evaluations. Participants must attend scheduled visits and follow study procedures throughout the treatment and follow-up periods.

Researchers are evaluating the combination of elranatamab, daratumumab, and lenalidomide compared with the combination of daratumumab, bortezomib, lenalidomide, and dexamethasone in adults with newly diagnosed multiple myeloma who are not candidates for transplant. This phase 3 study aims to determine whether the new combination offers better clinical benefits by assessing safety, tolerability, minimal residual disease negative complete response rates, and progression-free survival. The study has two parts. Part 1 focuses on characterizing the safety and tolerability of elranatamab combined with daratumumab and lenalidomide or with lenalidomide alone, and determining the best dose. Part 2 compares the effectiveness of elranatamab plus daratumumab and lenalidomide against the standard combination of daratumumab, bortezomib, lenalidomide, and dexamethasone in participants with newly diagnosed multiple myeloma. Participants receive study drugs according to their assigned group, and dosing and combinations vary by part and arm. Participants will undergo regular assessments including monitoring of disease status, progression, and response using criteria such as minimal residual disease and progression-free survival. Safety will be monitored through adverse event reporting and laboratory tests. Quality of life will also be evaluated using questionnaires. The study may last up to several years, with follow-up extending up to 97 months to assess long-term outcomes and survival.

Researchers are evaluating whether antibiotic treatment is necessary for children with community-acquired pneumonia caused by the bacterium Mycoplasma pneumoniae. This trial compares the effects of a commonly used antibiotic, azithromycin, with a placebo in children aged 3 to 17 years. The study addresses concerns about increasing antibiotic resistance and aims to improve treatment decisions for this common cause of pneumonia in children. Participants are randomly assigned to receive either azithromycin or a placebo for five days. The azithromycin group takes a daily dose of 10mgkg on the first day followed by 5mgkg on days 2 through 5. This randomized, double-blind, placebo-controlled trial takes place across multiple pediatric centers and includes both ambulatory and hospitalized children. The study involves initial screening to confirm Mycoplasma pneumoniae infection using a specific antibody test before starting the assigned treatment. During the study, researchers will monitor symptom duration, vital signs, and changes in patient care status for up to 28 days. They will also assess overall clinical outcomes, symptom resolution, quality of life impacts on the family, time to return to normal daily activities, and the development of any complications related to the infection. Follow-up includes clinical examinations and parent reports to track progress and safety throughout the study period.
