Researchers are looking for ways to treat germinal center B-cell-like diffuse large B-cell lymphoma (GCB DLBCL). DLBCL is a fast-growing blood cancer that affects B-cells. GCB is a type of DLBCL that affects young B-cells that are still maturing. The goal of this study is to learn if more people who receive zilovertamab vedotin (MK-2140) and R-CHP have the cancer respond (go away) than those who receive polatuzumab vedotin and R-CHP.

Researchers are evaluating the safety and effects of a medicine called disitamab vedotin for adults with advanced breast cancer that is hard to treat and has spread in the body. This study focuses on participants whose tumors express HER2 and who have received previous treatments for their advanced breast cancer. The goal is to understand how well this medicine works and its safety in these patients through a Phase 1b/2 open-label study. All participants will receive disitamab vedotin intravenously (IV) once every two weeks at the study clinic. They will continue the treatment until they or their doctor decide to stop, which could be due to cancer progression, side effects, or personal choice. During treatment, study visits occur every two weeks. After stopping treatment, participants will have follow-up visits about every six weeks, and later follow-up phone calls approximately every twelve weeks. Participants will undergo evaluations including assessments of their cancer response by the study doctors, following recognized criteria. The study team will monitor the participants for up to about two years or until their disease progresses or they pass away. This includes safety monitoring and collecting information about the medicine’s effects to determine its safety and effectiveness.

Researchers are evaluating the study medicine PF-08046054 compared to the standard chemotherapy drug docetaxel in adults with non-small cell lung cancer (NSCLC) that has spread or cannot be removed with surgery or radiation. Participants must have PD-L1 expression on 1% or more of their tumor cells and have experienced cancer progression during or after treatment with PD-L1 or PD-1 inhibitors, platinum-based chemotherapy, and targeted therapies for those with known genetic mutations. The trial is a Phase 3 randomized study to better understand how well PF-08046054 works alone compared to docetaxel alone. Participants will be randomly assigned to receive either PF-08046054 or docetaxel. Those in the PF-08046054 group will get intravenous (IV) infusions twice every 21-day cycle, while those in the docetaxel group will receive one IV infusion every 21 days. The treatment period may last up to 5 years if their NSCLC responds to the therapy. No other treatments are combined during the study period. Throughout the study, participants will have regular clinic visits for evaluations and monitoring to see how they respond to the treatment. Researchers will collect information on overall survival over approximately 5 years. They will also monitor safety and disease progression during these visits to understand the long-term effects and benefits of the treatments.

Researchers are evaluating a new medicine called PF-08634404 combined with chemotherapy for people aged 18 and older who have locally advanced or metastatic gastric, gastroesophageal junction, or esophageal adenocarcinoma. The study includes participants who have not received prior treatment for advanced or metastatic disease and are in good health based on medical tests. This research is designed as a Phase 2/3 trial to learn about safety, response, and compare this new treatment to an approved therapy called nivolumab plus chemotherapy. The study has two parts: the first part assesses the safety and response to PF-08634404 with chemotherapy, and the second part compares this combination to nivolumab with chemotherapy. Treatments are given intravenously in repeated cycles. Participants receive either PF-08634404 plus chemotherapy or nivolumab plus chemotherapy based on the study phase and group assignment. During the study, participants undergo regular evaluations including medical tests to monitor organ function and safety. Researchers will measure treatment response using RECIST 1.1 criteria, track adverse events, and assess progression-free survival and overall survival over approximately four years. Follow-up continues through 90 days after the last treatment to monitor side effects and overall health.

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 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 conducting the FLEX Registry to study patients with stage I to III breast cancer who receive MammaPrint and BluePrint testing on a primary breast tumor. This large-scale, population-based, prospective registry aims to create a comprehensive database of full genome expression linked with clinical data to explore new gene associations that may have prognostic or predictive value. The registry uses an adaptive design, allowing additional targeted substudies and arms to be added over time. The study involves patients from over 125 U.S. institutions, with an anticipated enrollment of around 30,000 participants. Treatment decisions are made by physicians following NCCN-approved regimens or recognized alternatives. MammaPrint and BluePrint tests are performed by Agendia using the full genome testing array. Data collection occurs at enrollment, during treatment, and at follow-up intervals of 1, 3, 5, and 10 years after diagnosis. Participants will have clinical data entered online at specified time points, with the goal of generating hypotheses for targeted subset analyses and further trials based on the genetic data collected. Outcome measures include the creation of a large registry for gene expression and clinical data over 10 years and the development of shared registry infrastructure to study smaller patient groups. This is an observational phase IV study focused on long-term data gathering and analysis.
