Researchers are evaluating insulin icodec, a once-weekly insulin injection, compared to insulin glargine, a once-daily injection, in adults with type 1 diabetes. The study aims to see how well weekly insulin icodec controls blood sugar levels compared to daily insulin glargine when both are combined with insulin aspart. This phase 3 study will last about 26 weeks, or roughly 8.5 months. Participants will receive either insulin icodec or insulin glargine, both given as subcutaneous injections. All participants will also use insulin aspart as a subcutaneous injection. The study compares these two insulin regimens to assess their effects on blood sugar control over the 26-week period. During the study, researchers will monitor changes in glycosylated hemoglobin (HbA1c) from the start of the study to week 26. Participants will follow the study protocol including self-measured plasma glucose profiles. Safety and efficacy will be evaluated throughout the treatment period to understand the impact of the insulin regimens on blood sugar control and participant health.

Researchers are evaluating the effectiveness and safety of combining inavolisib with a cyclin-dependent kinase 4 and 6 inhibitor (CDK4/6i) and letrozole compared to placebo plus CDK4/6i and letrozole. This study focuses on participants with endocrine-sensitive PIK3CA-mutated hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) advanced breast cancer. It aims to assess treatment outcomes in the first-line setting for this specific breast cancer type. Participants will be assigned to receive either oral inavolisib once daily or a matching oral placebo once daily. All participants will also receive a CDK4/6 inhibitor on either Days 1-21 or Days 1-28 of each 28-day cycle, along with daily oral letrozole. This randomized, double-blind study will compare these two treatment combinations to monitor differences in disease progression and safety. Throughout the study, researchers will evaluate progression-free survival from the time of randomization until disease progression or death, up to 7 years. Participants will undergo assessments including tumor measurements by RECIST criteria, performance status evaluations, and monitoring of blood and organ function before treatment begins. Safety and efficacy will be closely observed during treatment, aiming to provide detailed long-term data on the study therapies.

Researchers are evaluating how well elacestrant works compared to standard endocrine therapy in adults with node-positive, Estrogen Receptor-positive (ER+), Human Epidermal Growth Factor-2 negative (HER2-) early breast cancer who are at high risk of the cancer returning. This is a Phase 3 global, multicenter, randomized, open-label study focusing on participants who have had early invasive breast cancer removed and meet specific receptor and risk criteria. The study aims to understand which treatment better prevents invasive breast cancer over up to five years. Participants will receive either elacestrant or one of several standard endocrine therapies, including anastrozole, letrozole, exemestane, or tamoxifen, all given as oral tablets. Treatments will be administered according to the study plan, with careful monitoring throughout the trial. The study includes adults who have already received between 24 and 60 months of prior endocrine therapy, with or without certain inhibitors, and who have completed or stopped these treatments as required. During the study, participants will be monitored for invasive breast cancer-free survival for up to five years. Researchers will perform regular assessments to track treatment effects, side effects, and cancer recurrence. The study also includes safety monitoring and may involve additional tests or evaluations as needed to ensure participant well-being throughout the trial.

Researchers are evaluating the safety and effectiveness of Armour Thyroid compared to synthetic T4 treatment in adults with primary hypothyroidism who are currently stable on synthetic T4. The study focuses on assessing how well patients respond to dose conversion from synthetic T4 therapy to Armour Thyroid. This trial is conducted as a Phase 2/3 multicenter, double-blind, randomized, active-controlled study. Participants receive either Armour Thyroid in oral capsule or tablet form or synthetic T4 capsules. They must have been on a stable dose of synthetic T4 for at least 12 months before screening, with a dose of at least 25 mcg daily. The study compares both treatments over time to evaluate efficacy and safety in maintaining thyroid function. During the study, researchers monitor thyroid-stimulating hormone (TSH) levels to measure treatment response at week 55. They also track any adverse events related to the treatments for up to approximately 90 weeks. Participants undergo regular assessments to ensure safety and effectiveness throughout the study period.

Researchers are evaluating how effective, safe, and tolerable a vaccine for Clostridioides difficile (C. difficile) infection is in adults aged 65 years and older. The study focuses on reducing the number of C. difficile infections, which can cause diarrhea, in this older adult population. This is a Phase 3, placebo-controlled, double-blinded, randomized trial involving participants who are at risk because of recent or planned contact with healthcare systems or recent antibiotic use. Participants will receive either the C. difficile vaccine or a saline placebo. Both are given by injection into the upper arm muscle. The study includes 3 planned clinic visits and 3 phone visits initially, followed by yearly clinic visits until the study ends. Participants will remain in the study until enough infection events have occurred—this period may last up to about three and a half years, but could be shorter or longer depending on how quickly events happen or if the study stops early due to clear results. Throughout the study, participants will report any side effects such as local reactions and systemic events for 7 days after each vaccination, and adverse events for up to one month. Serious adverse events are monitored for up to 18 months after the last dose. If participants experience 3 or more loose stools within 24 hours during the study, they must save the next stool and contact the study team for infection testing. This ongoing monitoring helps assess the vaccine's impact on preventing medically attended C. difficile infections over time.

Researchers are investigating the addition of an immunotherapy drug called durvalumab to standard chemotherapy treatment in patients with MammaPrint High 2 Risk (MP2) stage II-III hormone receptor positive, HER2 negative breast cancer. This phase III trial aims to compare the effectiveness of usual chemotherapy alone versus chemotherapy combined with durvalumab. Immunotherapy with durvalumab may help the immune system attack cancer cells and prevent tumor growth and spread, while chemotherapy drugs like paclitaxel, doxorubicin, and cyclophosphamide work to stop cancer cells from growing or dividing. Previous studies suggest patients with an MP2 result might respond better to this combined treatment approach. Participants first undergo MammaPrint testing to confirm MP2 status before randomization into two groups. One group receives paclitaxel intravenously on days 1 and 8 every 14 days for 6 cycles, followed by doxorubicin and cyclophosphamide intravenously on day 1 every 14 days for 4 cycles. The other group receives the same chemotherapy schedule plus durvalumab intravenously over 60 minutes on specified cycles during both chemotherapy phases. Mammography is performed during screening, and optional tissue and blood samples are collected for future studies. Throughout the study, participants are monitored through various assessments including imaging, physical exams, laboratory tests, and quality of life questionnaires focusing on fatigue and physical and mental health. Researchers track breast cancer event-free survival and other outcomes such as treatment side effects and response rates. After completing treatment, patients are followed for up to 10 years or until death to evaluate long-term outcomes and safety.

Researchers are evaluating the effects of adding cemiplimab, an immunotherapy drug that blocks the PD-1 pathway to help the immune system attack tumor cells, to the usual treatment of docetaxel and ramucirumab in patients with stage IV or recurrent non-small cell lung cancer. This phase II/III Expanded Lung-MAP trial compares cemiplimab combined with docetaxel and ramucirumab versus docetaxel and ramucirumab alone, aiming to improve treatment outcomes in patients who previously received platinum chemotherapy and immunotherapy but developed resistance or disease progression. Participants are randomly assigned to one of two treatment arms. In Arm I, patients receive dexamethasone orally twice daily on days 0-2, ramucirumab and docetaxel intravenously on day 1 of each 21-day cycle. In Arm II, patients receive the same treatments plus cemiplimab intravenously on day 1 of each cycle. Treatment cycles continue every 21 days until disease progression or unacceptable side effects occur. Throughout the study, patients undergo regular blood sample collection and imaging scans such as CT or MRI to monitor disease status. During the study, participants are closely monitored with scans, blood tests, and physical exams to assess overall survival and other outcomes like progression-free survival, response rates, and treatment safety. Researchers also collect blood samples for future molecular studies. After completing treatment, patients are followed up every 3 to 6 months for up to 3 years to track long-term survival and health status. The study measures overall survival from randomization to death from any cause, assessed up to 3 years.

Researchers are evaluating the addition of olaparib, a PARP inhibitor, as maintenance therapy following surgery and chemotherapy in patients with pancreatic cancer that has been surgically removed and who have a pathogenic mutation in BRCA1, BRCA2, or PALB2 genes. This phase II randomized, double-blind study aims to determine if olaparib can improve relapse-free survival compared to placebo in these patients, who have completed perioperative chemotherapy and have no evidence of recurrent disease. Participants are randomly assigned to receive either olaparib or a placebo orally twice daily in 28-day cycles for up to 12 cycles, as long as there is no disease progression or unacceptable side effects. Throughout the treatment period, patients undergo imaging tests such as CT scans or MRI and blood sample collections. After completing the treatment cycles, patients are followed up at 30 days, every 4 months for the first year, and then every 6 months for up to 10 years after randomization to monitor their health and disease status. During the study, researchers assess relapse-free survival by documenting any return of cancer or death from 22 to 44 months after randomization. They also collect blood samples and perform imaging tests to monitor the disease and evaluate treatment effects. Safety is carefully monitored, and patients must have recovered from previous treatments before starting the study. The study includes long-term follow-up to observe survival outcomes and any differences based on genetic mutations or prior chemotherapy regimens.

Researchers are evaluating how to best recommend chemotherapy for patients with colon cancer after surgery by using the presence or absence of circulating tumor DNA (ctDNA) in the blood. This approach aims to identify microscopic residual tumor cells and may provide better risk prediction for cancer recurrence compared to traditional methods. The trial focuses on patients with Stage IIB, IIC, or III colon cancer who have undergone complete tumor removal. Participants will have their tumor tissue and blood tested centrally using the Signatera assay to determine ctDNA status. Patients without detectable ctDNA may avoid chemotherapy, while those with detectable ctDNA are considered at higher risk and will be randomly assigned to receive different chemotherapy regimens, including mFOLFOX6, CAPOX, or mFOLFIRINOX, given intravenously or orally over periods ranging from 3 to 6 months. The study includes initial screening, treatment, and possible second randomization for patients whose ctDNA status changes during monitoring. During the study, participants will undergo various assessments including blood tests, imaging scans, and performance evaluations to monitor their health and response to therapy. Researchers will track the time to ctDNA positivity and disease-free survival for up to 3 and 5 years, respectively. Safety and treatment effects will be closely observed throughout the study duration, ensuring thorough follow-up and monitoring for all participants.

Researchers are evaluating a phase II Lung-MAP treatment trial testing combinations of targeted drugs—capmatinib, osimertinib, and ramucirumab—to treat patients with advanced non-small cell lung cancer (NSCLC) that has spread and shows EGFR and MET gene changes. Capmatinib and osimertinib are kinase inhibitors that block abnormal proteins signaling cancer growth, while ramucirumab is an antibody that may stop new blood vessel growth needed by tumors. Targeting these gene changes may help shrink or control the cancer. Patients are randomized into two groups: one group receives capmatinib and osimertinib orally along with ramucirumab intravenously, while the other group receives capmatinib and osimertinib orally without ramucirumab. Throughout the study, participants undergo CT or MRI scans and provide blood samples. The treatments are given according to the assigned group to compare their effects and safety. During the trial, participants are closely monitored with imaging and blood tests to assess cancer progression and treatment side effects. The main measure is progression-free survival, tracking time until cancer worsens or death, over up to 3 years. Researchers also evaluate response rates, overall survival, toxicity, and collect tissue and blood samples to study tumor DNA. Participants' health status and laboratory values are regularly checked to ensure safety and effectiveness of the treatments.
