This trial is focused on adults with KRAS/NRAS and BRAF wild-type unresectable or metastatic left-sided colorectal cancer. It compares the length of time participants remain free from disease progression when treated with amivantamab combined with chemotherapy regimens (mFOLFOX6 or FOLFIRI) versus cetuximab combined with the same chemotherapy regimens. The study is a randomized, open-label Phase 3 clinical trial designed to evaluate progression-free survival over a period of up to 4 years and 2 months. Participants receive either amivantamab with chemotherapy drugs including 5-fluorouracil, leucovorin calcium or levoleucovorin, oxaliplatin, or irinotecan hydrochloride, or cetuximab with the same chemotherapy regimens (mFOLFOX6 or FOLFIRI). Treatments are administered as first-line therapy for their colorectal cancer. The trial assesses how these treatments affect disease progression and survival. During the study, participants will be monitored regularly through assessments and evaluations to measure progression-free survival. Researchers will gather data via blinded independent central review to ensure unbiased assessment of disease status. Participants are followed up for safety and treatment efficacy over the study duration, which may last over four years.

Researchers are evaluating two treatment combinations for patients with melanoma that has spread to the brain and has a specific BRAF-V600 mutation. This phase II trial compares encorafenib, binimetinib, and nivolumab against ipilimumab and nivolumab to determine which approach better controls and shrinks brain metastases from melanoma. The study also aims to assess overall survival, response rates, treatment duration, and side effects of each regimen. Participants are randomly assigned to one of two groups. One group receives encorafenib orally once daily, binimetinib orally twice daily, and nivolumab intravenously every 28 days. The other group receives nivolumab intravenously and ipilimumab intravenously during the first four cycles, with cycles every 21 days initially, then every 28 days thereafter. Treatment continues unless the disease worsens or side effects become unacceptable. After treatment ends, participants have follow-up visits every six months for two years, then yearly until three years after starting the study. During the trial, participants undergo brain MRIs to monitor tumor response using standardized criteria. Imaging, tumor tissue, spinal fluid, stool, and blood samples are collected for research. Safety and effectiveness are carefully assessed through scans, physical exams, lab tests, and side effect monitoring. Progression-free survival up to three years after randomization is the main outcome. Participants remain in the study for about three years with periodic evaluations to track their health and disease status.

Researchers are evaluating two surgical procedures, bilateral salpingectomy and bilateral salpingo-oophorectomy, to see how well they reduce the risk of ovarian cancer in women who have BRCA1 gene mutations. The study aims to determine if removing just the fallopian tubes (bilateral salpingectomy) is almost as effective as removing both the fallopian tubes and ovaries (bilateral salpingo-oophorectomy) in lowering ovarian cancer risk. This trial also assesses symptoms related to estrogen loss, quality of life, sexual function, cancer-related distress, decision-making about surgery, and treatment side effects in these patients. Participants choose between two groups: one group undergoes bilateral salpingectomy and may have their ovaries removed later, while the other group undergoes bilateral salpingo-oophorectomy. Both groups receive pelvic or transvaginal ultrasounds or pelvic MRI scans during screening, and blood samples are collected throughout the trial. Ancillary studies include quality-of-life assessments and questionnaires. The study also collects tissue and blood samples for future research. After surgery, participants have follow-up visits at 10 to 60 days, then at 6, 12, and 24 months, and annually for up to 20 years. Researchers monitor the time until any high-grade serous carcinomas develop, specifically ovarian, primary peritoneal, or fallopian tube cancers. They also track menopausal symptoms, sexual function, quality of life, cancer distress, medical decisions about surgery, and any adverse events during this long-term follow-up.

Researchers are evaluating the safety and effectiveness of an experimental drug combination, fianlimab and cemiplimab, in adults with advanced or metastatic melanoma, a type of skin cancer. This phase 3 study compares this combination with an approved treatment using relatlimab and nivolumab (Opdualag14). The study also investigates possible side effects, drug levels in the blood, and whether the body produces antibodies that might affect the drugs' performance or safety. Participants receive either fianlimab and cemiplimab together through intravenous (IV) infusions every three weeks or the comparator drugs relatlimab and nivolumab by IV every four weeks. The treatment period is followed closely by researchers who monitor how participants respond to the therapies and how well they tolerate them. During the study, participants undergo regular assessments including scans and laboratory tests to measure tumor response using standardized criteria (RECIST 1.1). Researchers also monitor safety, immune response, and drug levels for up to 72 months. The study requires participants to have measurable melanoma and good organ function, and they are observed for overall treatment effects and side effects throughout the trial.

Researchers are evaluating the effectiveness of active surveillance and chemotherapy treatments in pediatric, adolescent, and adult patients with low risk and standard risk germ cell tumors. This phase III trial focuses on monitoring patients after tumor removal and comparing the outcomes of carboplatin-based versus cisplatin-based chemotherapy regimens. The study aims to maintain high overall survival rates for low risk patients and to compare event-free survival between the two chemotherapy options in standard risk patients. Additional objectives include assessing side effects such as hearing loss and neuropathy, and exploring tumor marker changes and other biological measures related to treatment outcomes. Patients with low risk stage I germ cell tumors undergo surgery followed by observation, with the option to transfer to standard risk treatment if the tumor recurs. Those with standard risk tumors are randomly assigned to one of four chemotherapy regimens combining bleomycin, etoposide, carboplatin, or cisplatin. Treatments are given intravenously on specific schedules every 21 days for up to 3 or 4 cycles, depending on the group. Throughout the trial, patients receive imaging scans, blood tests, tumor biopsies if needed, and pulmonary function tests to monitor treatment response and side effects. Participants are closely followed after treatment completion with regular visits every 2 months for the first year, then less frequently up to 10 years. Researchers collect data through imaging, blood samples, lung tests, and questionnaires to measure survival, disease recurrence, and side effects like hearing loss. The study also includes exploratory analyses of tumor markers and patient-reported outcomes to better understand treatment impacts and improve future care for germ cell tumor patients.

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 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 the effects of cannabis and cannabinoid use on cancer-related symptoms in adults newly diagnosed with breast, colorectal, melanoma, non-Hodgkin lymphoma, or non-small cell lung cancer. This study focuses on patients who are planning to receive or have recently started systemic cancer treatments such as chemotherapy and immune checkpoint inhibitors (ICIs) targeting PD-1, PD-L1, or CTLA-4. The goal is to understand how cannabis use may be associated with symptom changes over time. Participants are enrolled in a non-interventional study where no experimental treatment is given. They complete surveys about their symptoms and cannabis use, and their medical records are reviewed regularly. The study tracks cancer-related symptoms monthly for up to 12 months after enrollment, allowing researchers to observe symptom patterns during ongoing cancer treatment. An optional substudy is available at select sites for patients with non-small cell lung cancer receiving paclitaxel and ICIs. During the study, participants complete online surveys in English or Spanish at their convenience, either at home or in clinic. Medical records are examined to gather information on treatments and health status. The main outcome measured is cancer-related symptoms, assessed monthly for one year. Safety monitoring includes ensuring participants have an expected life expectancy of at least six months and are not enrolled in hospice. The study aims to enroll 2000 patients across multiple sites in the United States.

Researchers are evaluating how well carboplatin chemotherapy works before surgery in men with high-risk prostate cancer who have inherited mutations in the BRCA1 or BRCA2 genes. This phase II trial aims to see if carboplatin can shrink tumors and lead to complete removal of cancer cells at the time of prostatectomy. The study also monitors progression-free survival, metastasis-free survival, overall survival, and treatment side effects. Additionally, specimens are collected for future research. Participants receive carboplatin intravenously before undergoing prostate surgery. If prostate-specific antigen (PSA) levels rise after surgery, patients undergo imaging tests such as CT, MRI, chest X-ray, or PSMA PET scans to monitor for cancer spread. Blood samples are collected throughout the trial to support further study and evaluation. During the study, participants have physical exams, medical history assessments, and laboratory tests including blood counts and liver and kidney function within 28 days before enrollment. Researchers track PSA progression and survival outcomes for up to five years after treatment. The trial includes regular imaging and safety monitoring to assess treatment effects and disease status over time.

Researchers are evaluating the effect of adding chemotherapy to immunotherapy (pembrolizumab) compared to using immunotherapy alone in treating older adults aged 70 and above with advanced non-small cell lung cancer (stage IIIB-IV). This phase III trial aims to determine if combining chemotherapy with pembrolizumab improves overall survival and other outcomes like progression-free survival, response rates, toxicity, and quality of life in this vulnerable patient group. Participants are randomly assigned to one of two treatment groups. In the immunotherapy-alone group, patients receive pembrolizumab intravenously every 21 days for four cycles, followed by maintenance pembrolizumab every 21 or 42 days for up to two years if there is no disease progression or unacceptable side effects. In the combination group, patients receive pembrolizumab plus a chemotherapy regimen chosen by their doctor, including drugs such as pemetrexed, carboplatin, nab-paclitaxel, or paclitaxel, given intravenously on specific schedules for four cycles, followed by the same pembrolizumab maintenance. Imaging scans like MRI, CT, and PET are performed at baseline and throughout the study. During the study, participants undergo various assessments including imaging scans, laboratory tests, and questionnaires to evaluate treatment effects, side effects, and quality of life. Researchers monitor overall survival for up to five years from randomization, with follow-up visits every three months for the first two years and every six months thereafter until five years. Additional exploratory analyses include safety, tolerability, and correlations with gut microbiome and geriatric assessments to better understand treatment outcomes in this population.
