Researchers are evaluating how to best recommend chemotherapy for patients with Stage IIB, IIC, or Stage III colon cancer based on the presence or absence of circulating tumor DNA ctDNA after surgery. This Phase IIIII trial explores whether ctDNA status can help guide decisions about the need for adjuvant chemotherapy and identify the optimal chemotherapy regimen for those at high risk of recurrence. Circulating tumor DNA is a promising biomarker that may detect microscopic residual cancer cells that traditional methods might miss. Participants are assigned to groups based on their ctDNA results after surgery. Those without detectable ctDNA ctDNA- may undergo serial monitoring without treatment or receive different chemotherapy regimens such as mFOLFOX6 or CAPOX for 3 to 6 months. Patients with detectable ctDNA ctDNA who have a higher risk of recurrence are randomized to receive either standard chemotherapy regimens like mFOLFOX6 or CAPOX for 6 months or a more intensive regimen called mFOLFIRINOX for 6 months. Central ctDNA testing is performed using the Signatera test to guide these assignments. During the study, participants have blood samples collected for ctDNA testing and undergo imaging scans to check for cancer recurrence. Researchers assess disease-free survival, overall survival, and chemotherapy compliance over several years. The study includes monitoring for safety and treatment effects, with follow-up planned for up to 5 years after randomization. Participants health status, laboratory tests, and tumor markers are regularly evaluated throughout the treatment and follow-up periods.

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.

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.
