Researchers are evaluating the experimental drugs pozelimab and cemdisiran for treating Geographic Atrophy GA, a late stage of Age-related Macular Degeneration AMD that affects central vision. The study aims to compare the progression rate of GA in patients receiving cemdisiran alone, the combination of pozelimab and cemdisiran, or a placebo. Additional goals include monitoring side effects, drug levels in the blood over time, and the bodys antibody response to these drugs. Participants will receive subcutaneous injections of either pozelimab combined with cemdisiran, cemdisiran alone, or a placebo. The study is randomized and double-masked with three groups receiving different treatments. Treatment and monitoring will continue through specified time points up to 104 weeks, with follow-up on safety and antibody responses extending even further. During the study, participants will attend regular clinic visits for eye exams, imaging using Fundus Autofluorescence to measure GA lesion growth, vision tests including visual acuity and contrast sensitivity, and blood tests to assess drug levels and antibody formation. Researchers will track treatment-emergent adverse events and evaluate changes in vision and GA progression over time. Participation lasts until the study completion date in April 2033, with primary outcomes assessed at 52 weeks and further evaluations up to 296 weeks.

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 conducting a study to evaluate the feasibility and acceptability of collecting patient-reported outcomes PROs from adolescents and young adults AYAs aged 18 to 39 who have been diagnosed with cancer. The study compares two approaches allowing participants to choose five health-related quality of life HRQOL domains they find most important Choice PRO versus completing five standard HRQOL domains selected by researchers Fixed PRO. The goal is to understand which method better supports AYA engagement and data completion. Participants are randomized into two groups. One group selects five from 15 PRO domains to complete at baseline and at 1, 3, 6, and 12 months, while the other group completes a fixed set of five domains at the same intervals. Questionnaires are completed online, facilitated by reminders via calls and text messages to improve adherence. The study also explores AYA preferences on how their PRO data should be shared with themselves, their families, and healthcare providers. During the study, participants complete assessments online at multiple timepoints, including baseline, 1, 3, 6, and 12 months, using a mix of computerized adaptive tests and static forms. Researchers measure feasibility based on the percentage of completed PROs and participant acceptability. The study monitors response rates, preferences, and data sharing views, aiming to enhance future patient-centered care and support in clinical trials involving AYAs with cancer.

Researchers are evaluating a connected customized treatment platform called CONCURxP to improve medication adherence in patients with metastatic hormone receptor-positive, HER2-negative breast cancer who are taking CDK46 inhibitors. The study compares CONCURxP, which includes the WiseBag medication monitoring device with personalized text message reminders and healthcare provider follow-ups, to enhanced usual care where patients only use the WiseBag and receive educational materials. The purpose is to see if these approaches affect how well patients follow their medication schedules, symptom burden, quality of life, and other outcomes over 12 months. Participants are randomly assigned to one of two groups Arm A uses the WiseBag dispenser and receives educational materials every 4 weeks for 12 months, while Arm B uses the WiseBag plus receives personalized text reminders, medication tracking, and provider follow-ups through CONCURxP for 12 months. A third group Arm C involves non-patient participants completing interviews 15 to 39 months after the first patient enrollment. After the 12-month intervention period, patients may be followed for an additional 6 months. During the study, patients complete surveys and electronic monitoring to assess medication adherence, symptom burden, quality of life, patient-provider communication, self-efficacy for symptom management, and financial worry at multiple time points. Some participants may also complete interviews about their experiences. Researchers review healthcare utilization, progression-free survival, and overall survival at 12 months. The study involves continuous monitoring using the WiseBag device and regular follow-ups to measure adherence and related outcomes.

Researchers are evaluating a text-based program designed to help rural cancer survivors who smoke to quit smoking. This phase III trial compares an eight-week scheduled gradual reduction SGR intervention delivered via personalized text messages combined with the National Cancer Institutes Smokefree.TXT service to a control group receiving a smoking cessation booklet. The study aims to assess how effective these approaches are in achieving biochemically validated smoking cessation six months after quitting, as well as their impact on quality of life. Participants are randomly assigned to one of two groups. The first group follows a personalized eight-week gradual reduction schedule, supported by cessation messages sent by text for 12 weeks. The second group receives the NCI Clearing the Air booklet to assist in planning gradual smoking cessation. After completing the interventions, participants are followed for a total of six months post-quit date to evaluate outcomes. During the study, participants will provide urine samples and complete questionnaires to measure smoking status and quality of life at baseline, 30 days, and six months after quitting. The research team uses biochemical validation to confirm smoking cessation. Participants must have texting capability on a cell phone or smartphone and be able to read and speak English. The total participation includes the intervention period plus follow-up to monitor smoking cessation and quality of life changes.

Researchers are investigating targeted therapies directed by genetic testing for patients with locally advanced or advanced solid tumors that have spread or progressed after standard treatments. This Phase 2 screening trial, called ComboMATCH, aims to match patients to specific combination treatments based on genetic mutations found in their tumor cells. The study seeks to improve treatment planning by using genetic information to guide therapy choices. Patients undergo tumor genetic screening using previously collected samples or a new biopsy if eligible and aged 18 or older. Based on their tumors genetic profile, patients are assigned to one of multiple treatment subprotocols involving different drug combinations. Treatments include oral, intravenous, and intramuscular drugs such as selumetinib, olaparib, fulvestrant, binimetinib, and others. Treatment cycles generally repeat every 28 days until disease progression or unacceptable toxicity. Patients may also undergo biopsies, blood collection, imaging scans CT, MRI, PET, echocardiograms, and bone marrow procedures as part of the study. Throughout the trial, participants have regular assessments including tumor biopsies, blood draws, imaging tests, and heart function monitoring. These evaluations occur during screening, treatment, and follow-up periods. Researchers measure patient enrollment, assignment to treatment arms, and treatment outcomes over up to 8 years. Safety is monitored via clinical evaluations and diagnostic tests. This comprehensive approach aims to evaluate responses to targeted therapies guided by tumor genetics for advanced solid tumors.

Researchers are evaluating early versus delayed treatment with venetoclax and obinutuzumab in patients newly diagnosed with high-risk chronic lymphocytic leukemia CLL or small lymphocytic lymphoma SLL. This phase III trial aims to determine if starting treatment before symptoms appear improves overall survival and other outcomes compared to starting treatment after symptoms develop. Venetoclax blocks a protein important for cancer cell survival, while obinutuzumab is an immunotherapy antibody that may help the immune system attack cancer cells. Participants are randomly assigned to receive either early or delayed treatment with venetoclax and obinutuzumab. Both groups receive obinutuzumab intravenously on specific days during six cycles and venetoclax orally daily for up to 12 cycles, each cycle lasting 28 days. Treatment continues unless disease progression or unacceptable side effects occur. During and after treatment, patients undergo CT scans, blood sample collection, and bone marrow biopsies. Throughout the study, participants are closely monitored with various assessments including laboratory tests, imaging, and quality of life questionnaires. Researchers measure overall survival, response rates, progression-free survival, and patient-reported outcomes over up to 10 years. Safety, tolerability, and disease markers such as measurable residual disease are also evaluated. Follow-up continues for 10 years after treatment completion to observe long-term outcomes.

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 evaluating the effects of neratinib alone compared to a combination of neratinib and palbociclib in treating patients with HER2 positive solid tumors, including gynecologic cancers. This phase II trial seeks to determine which treatment better controls disease progression and improves survival. The study also explores how specific tumor and blood markers relate to treatment response and resistance. Participants are randomly assigned to one of two treatment groups. One group receives neratinib orally once daily in repeated 28-day cycles, with an initial 14-day dosing period followed by continuous dosing. The other group receives the same neratinib schedule combined with palbociclib taken orally for 21 days each cycle. Patients undergo heart function tests, imaging scans like CT or MRI, blood sample collections, and tumor biopsies during screening and throughout the trial. Patients whose disease progresses on neratinib alone may switch to the combination treatment. During the study, participants have regular assessments including echocardiograms or MUGA scans, CT or MRI scans, and blood draws to monitor treatment effects and safety. Tumor biopsies may be performed before and during treatment. After completing study treatment, patients are followed every three months for two years to track progression-free survival and overall survival. The main outcome measured is the time from study entry until disease progression or death, assessed for up to two years.

Researchers are studying whether high-dose vitamin D can help prevent bone loss caused by androgen-deprivation therapy ADT in men with prostate cancer. This phase III trial focuses on men aged 50 and older who are undergoing ADT, which can weaken bones. Vitamin D helps the body absorb calcium, essential for strong bones, and the study aims to see if high doses of vitamin D can keep bones strong, reduce falls, and lessen fatigue in these patients. Participants are randomly assigned to one of two groups. One group receives high-dose vitamin D orally once a week for 52 weeks, while the other group receives a placebo on the same schedule. Both groups undergo blood collection and bone density scans during the study to monitor changes in bone health. Throughout the 52 weeks, participants will have bone density measured at multiple sites using dual-energy x-ray absorptiometry DXA, and researchers will track falls, fractures, quality of life, pain, fatigue, sleep, and daily activities through questionnaires and clinical records. The study includes regular assessments of blood vitamin D and calcium levels to ensure safety and effectiveness of the supplementation.
