This research focuses on participants with ovarian and breast cancers who have previously been treated with niraparib in GlaxoSmithKline/TESARO-sponsored studies. The aim is to provide continued access to niraparib and to better understand its long-term safety over an extended period. This global extension study involves adult participants who have met the primary objectives in prior clinical trials and are still benefiting from niraparib treatment. Participants will continue to take niraparib orally in the form of tablets or capsules once daily. This open-label, multicenter study allows participants who are judged by their investigators to benefit from ongoing treatment to receive niraparib beyond their initial studies. The treatment focuses on maintaining the therapy rather than comparing it to another drug or placebo. During the study, participants will be regularly monitored for safety through assessments such as adverse events, changes in performance status, blood tests, vital signs, and physical examinations. Researchers will also track the use of other medications. The study collects data for up to five years, ensuring comprehensive long-term safety information while participants adhere to scheduled visits and treatment plans.

Researchers are evaluating the drug disitamab vedotin, alone or combined with pembrolizumab, to treat urothelial cancer that expresses HER2. This cancer is locally advanced, cannot be removed by surgery, or has spread to other parts of the body. The study aims to see how well the drug works and how safe it is for participants by monitoring side effects and treatment responses. Participants will receive disitamab vedotin through an intravenous (IV) infusion every two weeks. Pembrolizumab, when given, is administered by IV on the first day of each six-week cycle. The study includes several groups, called cohorts, each with different treatment histories and eligibility criteria. Treatment and evaluation may continue for about two years. During the study, participants will have regular tests including scans to measure tumor response, lab tests, heart function checks, and monitoring for adverse events. Researchers will also track drug levels in the blood and any changes in heart function. The study will assess confirmed tumor responses and safety outcomes over approximately two years, with close monitoring to understand how participants respond to the treatments and any side effects experienced.

Researchers are evaluating a drug called sigvotatug vedotin alone and in combination with pembrolizumab, with or without chemotherapy, to determine its safety and effects in people with various advanced solid tumors. This Phase 1 study includes participants with specific cancers like non-small cell lung cancer, head and neck squamous cell cancer, HER2-negative breast cancer, esophageal cancers, ovarian cancer, and others. The trial aims to find out the side effects of sigvotatug vedotin and whether it can treat these solid tumors effectively. The study is divided into four parts. Part A focuses on finding the right dose of sigvotatug vedotin. Part B tests the safety and effectiveness of that dose. Parts C and D look at the safety and effectiveness of sigvotatug vedotin combined with pembrolizumab alone or with chemotherapy drugs carboplatin or cisplatin. Participants receive these drugs intravenously, with pembrolizumab given every 3 or 6 weeks and chemotherapy every 3 weeks depending on the drug. During the study, participants undergo tumor biopsies, physical exams, and disease assessments to monitor treatment effects. Researchers track side effects, lab abnormalities, and dose-limiting toxicities for up to 30-37 days after the last dose of sigvotatug vedotin, and for up to 3 years after pembrolizumab treatment. The study follows participants with regular safety monitoring and evaluations of tumor response throughout the trial.

Researchers are evaluating the addition of nivolumab to the usual treatment of paclitaxel and ramucirumab in patients with advanced or locally unresectable stomach or esophageal adenocarcinoma. This phase II/III trial aims to determine if adding nivolumab improves progression-free survival and overall survival compared to paclitaxel and ramucirumab alone. The study also assesses response rates, disease control, safety, tolerability, and quality of life in participants with PD-L1 CPS 21 1 advanced gastric or esophageal cancer. Participants are randomly assigned to one of two treatment groups. The first group receives nivolumab IV on day 1 of each 28-day cycle, ramucirumab IV on days 1 and 15, and paclitaxel IV on days 1, 8, and 15. The second group receives ramucirumab IV on days 1 and 15 and paclitaxel IV on days 1, 8, and 15 of each cycle. Treatment continues every 28 days until disease progression or unacceptable side effects occur. Optional blood samples may be collected during the study. Imaging with CT and MRI is performed throughout. Participants undergo scans and assessments at baseline and during treatment to monitor cancer progression and treatment effects. They also complete questionnaires on quality of life and symptoms. After treatment ends, participants are followed up at 30, 60, and 90 days and then every 6 months for up to 3 years. Researchers measure progression-free survival and overall survival as primary outcomes, along with other safety and patient-reported measures.

Researchers are collecting blood and tissue samples from people with and without cancer to study and evaluate tests that could help detect cancer early. The goal is to create a blinded reference set of samples to validate blood-based tests for early detection of multiple types of cancer, including leukemia, lymphoma, breast, lung, and others. The study also aims to assess how well these tests perform at the time of initial cancer diagnosis, considering different tumor types and cancer stages. Participants complete a baseline questionnaire and provide blood samples at registration and again 12 months later. Those diagnosed with cancer may also provide tissue samples at these times. The study includes patients aged 40 to 75 years, with cancer diagnoses at various stages or individuals without cancer. Special procedures are in place for patients with high suspicion of certain cancers before confirmation. During the study, researchers collect detailed information through questionnaires, blood draws, and tissue sampling to analyze test accuracy. Participants are monitored for up to one year after registration to follow outcomes. The primary measure is providing this blinded set of blood samples to help validate future cancer detection tests, supporting research that could improve early diagnosis and treatment.

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 two different methods for monitoring pancreatic cysts to determine which approach leads to better outcomes for patients with these cysts. The study compares a lower intensity surveillance schedule with a higher intensity surveillance schedule in patients aged 50 to 75 years. The study also aims to assess differences in surgical complications, pancreatic cancer rates, mortality, costs, healthcare use, patient quality of life, anxiety, financial distress, adherence to surveillance, and the predictive value of biomarkers and radiomic markers for cancer or dysplasia. Participants are randomly assigned to one of two surveillance arms. In the low intensity arm, patients receive MRI or CT scans at the start and one year later, then repeat imaging every two years if no abnormalities are found. If positive features appear, imaging frequency increases. In the high intensity arm, surveillance frequency varies by cyst size, ranging from MRI or CT every six months to combined imaging and endoscopic ultrasound (EUS) every 3-6 months for larger cysts. EUS is used to further evaluate cysts based on size and findings. After imaging procedures, patients are followed for five years from enrollment. During the study, patients undergo procedures including MRI, CT, and EUS, along with quality-of-life and questionnaire assessments. Researchers will monitor clinical outcomes, imaging results, healthcare utilization, costs, patient-reported outcomes, and biomarker performance. Safety and adherence to surveillance schedules will be tracked. The study lasts five years after the initial registration to capture long-term outcomes related to pancreatic cyst monitoring.

Researchers are evaluating whether breast conservation surgery combined with endocrine therapy can achieve a similar rate of invasive or non-invasive ipsilateral breast tumor recurrence (IBTR) compared to breast conservation surgery followed by breast radiation and endocrine therapy in patients with Stage I, hormone sensitive, HER2-negative breast cancer with an Oncotype recurrence score of 18 or less. This Phase III trial builds on the established role of radiation after lumpectomy, aiming to identify if radiation can be safely omitted in certain low-risk patients to reduce treatment burden and side effects. Participants receive either breast radiation plus endocrine therapy or endocrine therapy alone. Radiation therapy involves external beam radiation to the whole breast with or without a boost, partial breast irradiation, or accelerated partial breast irradiation, starting within 12 weeks after the last breast surgery. Endocrine therapy is given for a minimum of 5 years, with the specific drug choice and schedule determined by the treating physician. Endocrine therapy may begin before, during, or after radiation therapy, depending on the treatment group. Throughout the study, participants undergo regular assessments including imaging such as mammograms or MRI within six months before enrollment, and clinical evaluations to monitor tumor recurrence. The main outcome measured is the time to invasive or non-invasive ipsilateral breast tumor recurrence over five years. Safety, adherence to therapy, and recovery from surgery are also monitored. The total participation period includes at least five years to evaluate long-term recurrence rates.

Researchers are evaluating if adding adjuvant chemotherapy (ACT) to ovarian function suppression (OFS) plus endocrine therapy (ET) improves invasive breast cancer-free survival (IBCFS) compared to OFS plus ET alone. This Phase III trial focuses on premenopausal women with early-stage breast cancer that is estrogen receptor (ER)-positive, HER2-negative, and has a 21-gene recurrence score between 16-25 for node-negative patients or 0-25 for patients with 1-3 positive nodes. The study addresses the need for better treatment options for younger women diagnosed with this type of breast cancer, as younger age is linked to worse outcomes despite standard therapies. Participants receive one of two treatments: either OFS combined with an aromatase inhibitor (AI) for five years or adjuvant chemotherapy followed by the same OFS plus AI regimen. The specific AI and GnRH agonist used, along with their dosing schedules, are chosen by the investigator, commonly including goserelin, leuprolide, or triptorelin administered monthly or every three months. Bilateral oophorectomy may be used instead of ovarian suppression if preferred. Endocrine therapy beyond five years is at the investigator's discretion. During the trial, participants will be closely monitored for invasive breast cancer-free survival over an 11-year period from randomization. Assessments include clinical evaluations, hormone receptor testing, tumor staging, and genetic recurrence scoring prior to enrollment. Safety and effectiveness data will be collected throughout the study, with particular attention to treatment side effects and long-term outcomes. The trial involves detailed eligibility screening and ongoing follow-up to ensure accurate measurement of the study's primary outcome.

Researchers are evaluating the addition of the immunotherapy drug atezolizumab to standard chemotherapy treatment for patients with poorly differentiated extrapulmonary neuroendocrine carcinoma that is advanced, metastatic, unresectable, or recurrent. This phase II/III trial aims to compare the effects of combining atezolizumab with platinum-based chemotherapy (cisplatin or carboplatin) and etoposide against standard chemotherapy alone. The study also compares the use of atezolizumab only during initial treatment versus continuing it beyond induction treatment. Participants are randomly assigned to one of three groups. In Arm 1, patients receive induction treatment with atezolizumab plus platinum chemotherapy and etoposide every 21 days for four cycles, followed by maintenance atezolizumab every 21 days for up to 17 cycles. In Arm 2, patients receive the same induction treatment but then undergo observation for one year without maintenance therapy. In Arm 3, patients receive platinum chemotherapy and etoposide only for four cycles followed by observation for one year. All treatments are given intravenously. Patients also have blood samples collected and undergo CT scans and/or MRI scans during the trial. Throughout the study, participants are monitored with imaging and blood tests to assess their response and safety. After completing treatment, patients are followed for up to five years to measure overall survival and other outcomes like progression-free survival, response rates, and safety. The study also collects tumor and blood samples for future biomarker research.
