Researchers are studying how certain factors like age, gender, other medical conditions, and the type of immunotherapy affect whether patients with malignant solid tumors develop mild or serious side effects from immune checkpoint inhibitor treatments. This observational study aims to develop and validate a model that predicts severe immune-related side effects during the first year of immunotherapy, while also assessing quality of life and adverse events over 12 months. The study is sponsored by the SWOG Cancer Research Network and includes translational medicine goals such as evaluating cytokine levels as predictors and establishing a tissue and blood sample repository. Participants will provide a tissue sample at the start of their routine cancer treatment and complete questionnaires at multiple time points at treatment start, and weeks 4, 12, 24, and 52. They may also provide optional blood samples during the study. This design allows researchers to monitor immune-related side effects and patient-reported outcomes over time. During the study, participants will complete various questionnaires to report their quality of life, cognitive function, and side effects. Blood and tissue samples will be analyzed to explore predictive markers of toxicity. Researchers will track the occurrence of severe immune-related side effects over 52 weeks and assess changes in patient-reported outcomes. The study includes ongoing monitoring and data collection, with participation lasting approximately one year from treatment start.

Researchers are studying adolescent and young adult AYA cancer survivors who had Hodgkin or non-Hodgkin lymphoma to understand how social and genetic factors affect their health outcomes after treatment. These survivors face unique biological, clinical, psychological, and social challenges that may influence their risks for illness and early death compared to older or childhood cancer patients. The study aims to identify conditions increasing these risks and to better meet the needs of AYA cancer survivors. Participants will complete questionnaires about their quality of life and provide blood samples at the start of the study and again at 6, 12, 18, and 24 months. This observational study collects health and treatment information without administering any medical treatments. The study assesses social-environmental risks, individual resilience factors, and gene expression changes to understand their impact on survival and quality of life. Participants will be asked to fill out health-related questionnaires and provide blood samples multiple times over two years. Researchers will measure disease-free survival, overall survival, comorbidities, and quality of life during this period. The study involves ongoing monitoring through questionnaires and blood tests to gather detailed data on how social and genetic factors influence long-term outcomes for AYA lymphoma survivors.

Researchers are evaluating the effects of pembrolizumab alone compared to the standard treatment of chemotherapy cisplatin or carboplatin combined with radiation therapy after surgery in patients with recurrent or second primary head and neck squamous cell carcinoma. This phase II trial aims to assess overall survival, disease control, metastasis rates, and side effects in high-risk patients, while also exploring whether high PD-L1 expression predicts better responses to pembrolizumab. Participants are randomly assigned to one of two treatment groups. One group receives intravenous cisplatin or carboplatin weekly for six cycles alongside daily intensity-modulated radiation therapy or proton beam radiation totaling 30 sessions. The other group receives intravenous pembrolizumab every six weeks for up to nine cycles. Throughout treatment, participants undergo CT or MRI scans to monitor their condition. After completing treatment, participants are followed up 30 days later and then every six months for up to five years. During the study, researchers evaluate overall survival from randomization to death, adverse events for up to five years, disease-free survival, and PD-L1 expression levels. The study monitors patients closely with imaging and clinical assessments to track treatment effects and safety over time.

Researchers are evaluating the addition of pembrolizumab immunotherapy to standard chemotherapy for patients with stage IIA, IIB, IIIA, or IIIB non-small cell lung cancer NSCLC that has been completely removed by surgery. This phase III trial aims to compare disease-free survival and overall survival among different treatment approaches, including chemotherapy alone, chemotherapy followed by pembrolizumab, and chemotherapy combined with pembrolizumab. The study also assesses quality of life and adverse event rates in these patient groups. Participants are randomly assigned to one of three groups. One group receives only chemotherapy with observation afterward. The other two groups receive chemotherapy followed by pembrolizumab or chemotherapy combined with pembrolizumab. Chemotherapy involves one of four platinum doublet regimens administered every 21 days for four cycles, depending on the physicians choice. Pembrolizumab is given intravenously over 25-40 minutes, either after chemotherapy or alongside it, repeated every 21 days or every 6 weeks for multiple cycles. Patients also undergo heart ultrasound, MRI, CT scans, and blood sample collections as part of the study. During the trial, participants have regular medical assessments including imaging and blood tests to monitor their health. Follow-up visits occur 6 weeks after treatment, then every 3 months for 2 years, every 6 months for years 2-4, and annually up to 10 years from randomization. Researchers measure disease-free survival as the main outcome, tracking the time until cancer recurrence or death. They also evaluate overall survival, side effects, drug tolerability, and patient-reported quality of life over time.

Researchers are investigating treatments for men with prostate cancer that has returned after surgery, focusing on those who experience a rise in prostate-specific antigen PSA levels, indicating biochemical recurrence. The study examines whether adding enhanced systemic therapy apalutamide combined with abiraterone and prednisone to standard care, which includes prostate radiation therapy and short-term androgen deprivation, improves outcomes. Additionally, for patients whose cancer has spread beyond the pelvis as detected by PET imaging, the study evaluates the benefit of adding metastasis-directed radiation therapy. Participants undergo baseline PETCT or PETMR scans to determine the extent of cancer spread. Based on these results, they are randomized into one of four treatment arms standard radiation with androgen deprivation, enhanced therapy including apalutamide, or enhanced therapy plus targeted radiation for metastatic disease. Treatments involve various forms of radiation therapy, androgen deprivation drugs, and oral apalutamide, administered over six months in the absence of disease progression or unacceptable side effects. Some patients may receive repeat PET scans to assess treatment response. During the study, participants have scheduled assessments including imaging, blood tests measuring PSA levels, and quality-of-life questionnaires over up to ten years. Follow-up visits occur every three months for the first two years, then less frequently up to ten years. Researchers monitor progression-free survival, overall survival, event-free survival, PSA progression, adverse events, and quality of life measures including cognitive function and fatigue. This long-term monitoring aims to determine the effectiveness of the added therapies compared to standard treatment alone.

Researchers are evaluating treatment options for patients newly diagnosed with multiple myeloma who are considered frail or intermediate-fit and who are not candidates for stem cell transplant. This phase III trial compares three different three-drug induction regimens followed by either single or double drug maintenance therapies. The study aims to find which drug combination best controls the cancer and improves patient outcomes while considering patients age, other health conditions, and physical function. Participants are randomly assigned to one of three treatment arms. In Arm 1, patients receive bortezomib, lenalidomide, and dexamethasone with bortezomib given subcutaneously and the others taken orally for up to 9 cycles, followed by lenalidomide maintenance. Arm 2 involves daratumumab with hyaluronidase-fihj given subcutaneously, lenalidomide, and dexamethasone for induction, followed by lenalidomide maintenance. Arm 3 includes the same induction as Arm 2, but maintenance therapy combines daratumumab with hyaluronidase-fihj and lenalidomide. Each cycle lasts 28 days, and treatment continues without disease progression or unacceptable side effects. During the trial, participants undergo regular assessments including tumor measurements, blood tests, and quality-of-life questionnaires. Researchers monitor progression-free survival, overall survival, response rates, minimal residual disease status, and patient-reported symptoms and health status. After completing treatment, patients are followed up every 3 months for one year, every 6 months for two years, and then annually for up to 10 years to monitor long-term outcomes and safety.

This trial investigates the addition of panitumumab to standard chemotherapy for patients with KRAS wild type pancreatic ductal adenocarcinoma that cannot be removed by surgery or has spread locally or to other parts of the body. The study aims to compare overall survival and other clinical outcomes between patients receiving panitumumab plus chemotherapy and those receiving chemotherapy alone. It also evaluates quality of life, treatment toxicity, and patient-reported symptoms. Participants are randomly assigned to one of two groups. One group receives panitumumab intravenously on days 1 and 15, combined with one of several chemotherapy regimens given intravenously in 28-day cycles, repeating if tolerated without disease progression. The other group receives the same chemotherapy regimens without panitumumab, also in 28-day cycles. Throughout the study, patients undergo CT scans and blood sample collection. After treatment, they are followed for up to three years. During the study, participants will have regular imaging and blood tests to monitor disease status and treatment effects. Quality of life and symptom questionnaires are completed at specified intervals. Researchers measure overall survival, progression-free survival, response rates, duration of response, and treatment side effects. Safety is monitored up to 30 days after treatment ends. Specimens are banked for future research, and patient-reported outcomes help assess the impact of treatment over 24 weeks.

Researchers are evaluating a master screening protocol called Lung-MAP for patients with previously treated non-small cell lung cancer. This phase IIIII trial aims to develop a genomic screening method for large cancer populations and assign participants to appropriate sub-studies based on specific cancer biomarkers. The goal is to compare new targeted therapies designed to block cancer growth or spread with standard care, including sub-studies for patients not eligible for biomarker-driven treatments. The study involves screening patient specimens to determine eligibility for various biomarker-driven or non-matched sub-studies within the Lung-MAP umbrella protocol. This is a screening study without direct interventions instead, patients are assigned to different treatment sub-studies, each operating independently. The protocol also includes an optional ancillary study evaluating attitudes about the return of somatic mutation findings suggestive of germline mutations. Participants provide tumor tissue for biomarker testing, including molecular profiling and PD-L1 analysis, and may submit fresh biopsies and blood samples for circulating tumor DNA testing. Researchers will monitor screening success rates up to three years and collect patient and physician feedback on genetic findings. Participation involves signing informed consent, providing smoking history, and possibly completing surveys. The study duration and assessments vary depending on sub-study assignment and patient progression.

Researchers are investigating whether adding the drug Docetaxel to the usual hormone treatments, Androgen Deprivation Therapy ADT and Androgen-Receptor Pathway Inhibitor ARPI, can better control metastatic castration sensitive prostate cancer in men who have not responded optimally to initial hormone therapy. This phase III, international, open-label, randomized trial seeks to compare the effectiveness of this combined approach against the standard hormone therapy alone. Participants will be randomly assigned to receive either the standard hormone therapy with ADT plus ARPI or the same hormone therapy combined with Docetaxel chemotherapy. The trial focuses on men with metastatic prostate cancer who continue to have elevated PSA levels after 6 to 12 months of hormone-targeting treatment. Treatments are administered according to physician choice and assignment, and the study evaluates outcomes over a long period. During the trial, participants will be closely monitored with assessments including PSA levels and clinical progression over 39 months. Researchers will measure overall survival as the primary outcome, along with secondary outcomes such as PSA progression, PSA response, PSA kinetics, and progression-free survival. Participants must be accessible for treatment and follow-up to allow for complete documentation of treatment effects and adverse events throughout the study duration.

This trial investigates whether high dose chemotherapy followed by an autologous stem cell transplant ASCT improves progression-free survival compared to observation alone in patients with peripheral T-cell lymphoma who have achieved a complete response after initial chemotherapy. The study also evaluates overall survival, relapse, mortality, and the impact of minimal residual disease on transplant benefits. This phase III randomized trial aims to clarify if adding ASCT after remission offers additional benefit beyond standard observation. Participants are randomly assigned to one of two groups. One group receives standard observation including blood sample collection and optional bone marrow tests, along with CT or PETCT scans throughout the study. The other group undergoes stem cell mobilization, leukapheresis, high dose chemotherapy, and ASCT, with similar sample collections and imaging. After treatment, patients are followed for up to 12 years to monitor outcomes. During the study, participants have regular blood tests, optional bone marrow biopsies, and imaging scans to assess disease status. Follow-up visits occur every 3 months for 2 years, then every 6 months for 3 years, and yearly thereafter. Researchers measure progression-free survival as the main outcome, along with overall survival and relapse rates. Safety and long-term effects are monitored throughout the 12-year observation period to evaluate the treatments impact.
