Targeted Therapy Directed by Genetic Testing in Treating Patients With Advanced Refractory Solid Tumors, Lymphomas, or Multiple Myeloma (The MATCH Screening Trial)

This phase II MATCH screening and multi-sub-trial studies how well treatment that is directed by genetic testing works in patients with solid tumors, lymphomas, or multiple myelomas that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) and does not respond to treatment (refractory). Patients must have progressed following at least one line of standard treatment or for which no agreed upon treatment approach exists. Genetic tests look at the unique genetic material (genes) of patients' tumor cells. Patients with genetic abnormalities (such as mutations, amplifications, or translocations) may benefit more from treatment which targets their tumor's particular genetic abnormality. Identifying these genetic abnormalities first may help doctors plan better treatment for patients with solid tumors, lymphomas, or multiple myeloma.

An Investigational Drug (TPST-1495) in Patients With Familial Adenomatous Polyposis

This open-label phase II trial tests how well TPST-1495 works in reducing the number of polyps in the small bowel and colon in patients with familial adenomatous polyposis (FAP). FAP is an inherited condition in which numerous polyps (growths that protrude from mucous membranes) form on the inside walls of the colon and rectum. It increases the risk for colon cancer. TPST-1495 binds to specific prostaglandin receptors. TPST-1495 is a dual antagonist of the prostaglandin E2 (PGE2) receptor subtypes EP2 and EP4, while sparing the immune-stimulating EP1 and EP3 receptors. TPST-1495 may help reduce the number of polyps in the small bowel and colon in patients with FAP.

The Vanguard Study: Testing a New Way to Screen for Cancer

The Vanguard Study is a feasibility study to explore several aspects of evaluating multi-cancer detection (MCD) tests in a future definitive randomized controlled trial. An MCD test measures markers in the blood in order to screen for multiple cancers simultaneously. There is a need to understand how MCDs may work as cancer screening tools. The goal of cancer screening is to reduce the burden of cancer by identifying cancers before they show symptoms or signs, when treatment is likely to be most effective. In this study, adults aged 45-75 without cancer will be randomly assigned to one of 3 groups: 2 separate MCD test groups or a control group. These two MCD tests will not be compared to each other but will be compared to cancers detected in the control group. This study will provide early information on how well MCD tests perform as cancer screening tools. It will also help researchers understand how patients and their doctors make decisions about their care when the MCD test result comes back as normal (negative) or abnormal (positive).

Determining the Biodistribution of an Imaging Tracer (68Ga-FAPi-46) in Patients With Solid Tumors or Hematologic Cancers

This phase I trial is evaluating a new imaging tracer (68Ga-FAPi-46) with positron emission tomography (PET)/computed tomography (CT) to determine where and to which degree the tracer (68Ga-FAPi-46) accumulates in normal and cancer tissues (the biodistribution) in patients with solid tumors or hematologic (blood) cancers. PET is an established imaging technique that utilizes small amounts of radioactivity attached to very minimal amounts of tracer, in the case of this research, 68Ga-FAPi-46. Because some cancers take up 68Ga-FAPi-46, it can be seen with PET. CT utilizes x-rays that traverse the body from the outside. CT images provide an exact outline of organs and potential inflammatory tissue where it occurs in a patient's body. Combining a PET scan with a CT scan can help make the image easier to interpret. PET/CT scans are hybrid scanners that combine both modalities into a single scan during the same examination.

A Multilevel Intervention to Increase Colorectal Cancer Screening Tests in Patients With Abnormal Fecal Immunochemical Test Results, PROACT Trial

This clinical trial studies whether an intervention that addresses two or more levels of care (multilevel intervention) increases follow-up of abnormal, non-invasive, colorectal cancer (CRC) screening test results. The fecal immunochemical test (FIT) is a non-invasive, stool-based, CRC screening test. FITs are relatively inexpensive and can be completed at home, for these reasons, it is a preferred method of CRC screening in healthcare settings that care for under-resourced patients or have limited colonoscopy access. For FIT-based CRC screening to be effective, abnormal results must be followed by a colonoscopy, however many patients fail to complete this recommended follow-up test. The multilevel intervention addresses barriers to follow-up colonoscopy at the patient and health system levels of care through a CRC screening patient navigator, an educational video, and transportation assistance. The navigator provides patient support and assistance with colonoscopy scheduling. The educational video addresses identified patient fears around colonoscopies. Transportation assistance is offered after the colonoscopy through a rideshare program to address transportation barriers. Therefore, this multilevel intervention may increase follow-up colonoscopy completion in patients with abnormal FIT results.

Assessment of Current Biomarker Testing Practices for Common Solid Cancers in Precision Oncology in the Community Setting

This trial assesses current biomarker testing practices for common solid cancers in precision oncology in the community setting. Cancer biomarkers are used for diagnosing the disease, determining prognosis, predicting response to a targeted therapy, or monitoring response to therapy. Testing quality, including accuracy and timeliness, is imperative for correct disease prognosis and identification of patients who may or may not benefit from a targeted therapy. Assessing current biomarker testing practices may help doctors identify gaps and variations in testing as well as on potential ?best practices? that may be informative and generalizable to community oncology programs.

Phase 1/2 Trial of S241656 in Selected RAS/MAPK Mutation- Positive Malignancies

BDTX-4933-101 is a first-in-human, open-label, Phase 1/2 dose escalation, dose optimization and expansion study designed to evaluate the safety and tolerability of S241656 as monotherapy and in combination with other anti-cancer therapies in participants with selected advanced malignancies. The study population for the Dose Escalation part of the study comprises adults with recurrent advanced/metastatic non-small cell lung cancer (NSCLC), Gastrointestinal (GI) cancers, and other solid tumors harboring KRAS, HRAS, NRAS, BRAF, and/or CRAF (Rapidly Accelerated Fibrosarcoma (RAF1)) mutations or alterations. A dose optimization part in adults with NSCLC may follow the dose escalation phase if the sponsor, in consultation with the safety review committee, decides it is necessary to further characterize the optimal dose. However, the study may also proceed directly to the expansion phase. The study population for the Dose Expansion part of the study comprises adults with advanced/metastatic NSCLC with KRAS and/or BRAF mutations, and with Pancreatic Ductal AdenoCarcinoma (PDAC), ColoRectal Cancer (CRC), and Biliary Tract Cancer (BTC) with KRAS, HRAS, NRAS, BRAF, and/or CRAF (RAF1) mutations and alterations. All patients will self-administer S241656 orally in 28-day cycles until disease progression, toxicity, withdrawal of consent, or termination of the study.

Testing a Combination of Vaccines for Cancer Prevention in Lynch Syndrome

This phase IIb trial tests whether Tri-Ad5 in combination with N-803 works to prevent colon and other cancers in participants with Lynch syndrome. Each of the three injections in Tri-Ad5 vaccine contain a different substance that is in precancer and cancer cells. Injecting these substances may cause the immune system to develop a defense against cancer that recognizes and destroys any precancer and cancer cells that produce these proteins in the future. N-803 may increase immune responses to other vaccines. Giving Tri-Ad5 in combination with immune enhancing N-803 may lower the chance of developing colon and other cancers in participants with Lynch syndrome.

A Dietary Intervention (Soy Soft Pretzels) for Reducing Chronic Inflammation in Obese Individuals

This clinical trial compares the effects of soy soft pretzels versus wheat pretzels on inflammatory markers in individuals with obesity. Obesity is a serious public health problem that can lead to chronic inflammation, which is associated with many negative health conditions and some types of cancer. Soy versus wheat pretzels may be processed by the body differently, and the components in these pretzel snacks may be helpful for reducing inflammation. Soy soft pretzels are made with soybeans, which contain many natural chemicals that may be beneficial to human health, such as isoflavones. Existing research has suggested that diets enriched with isoflavones may help reduce inflammation. However, the relationship between soy-rich diets and the immune systems of obese individuals is not well understood. This trial may help researchers determine whether soy soft pretzels are useful for lowering markers of chronic inflammation, compared to wheat pretzels, in individuals with obesity.

Testing for Safety and Colorectal Cancer Preventive Effects of ONC201

The purpose of this phase I trial is to test the safety and cancer preventive effects of different doses of ONC201 in people with familial adenomatous polyposis (FAP) or a history of multiple polyps. People with familial adenomatous polyposis (FAP) or a history of multiple polyps are at higher than average risk of developing colorectal cancer. ONC201, now known as dordaviprone, is a drug that may stop cancer cells from growing. This drug has been shown in previous studies to cause cancer cell death but not harm normal cells. If successful, this study may help us develop a new option for colorectal cancer prevention.

Immune Response Activation for the Treatment of Unresectable Metastatic Colorectal Cancer or CEA Positive Metastatic Breast Cancer

This phase I trial studies the side effects and best dose of M5A-IL2 immunocytokine (M5A-ICK) combined with stereotactic body radiation therapy (SBRT) and to see how well they work in treating patients with colorectal cancer or xarcinoembryonic antigen (CEA) positive breast cancer that cannot be removed by surgery (unresectable) or has spread from where it first started (primary site) to other places in the body (metastatic). Carcinoembryonic Antigen (CEA) is a protein that is present in most colorectal cancers and in many other cancers, such as breast cancer, as well. SBRT uses special equipment to position a patient and deliver radiation to tumors with high precision. This method may kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. Cytokines are signaling proteins that help control inflammation in the body. They allow the immune system to mount a defense if germs or cancer or other substances that can make people sick enter the body. Interleukin-2 (IL-2) is a powerful cytokine able to regulate the immune responses that are important for anticancer immunity. Immunocytokines (also called antibody-cytokine fusion proteins) are small proteins that regulate the activity of immune cells. The M5A-IL2 immunocytokine (M5A-ICK) combines the cancer targeting features of the M5A antibody with the immune system regulation properties of the cytokine IL-2. Giving M5A-ICK in combination with standard of care (SOC) SBRT may work better in treating patients with unresectable metastatic colorectal cancer or CEA positive metastatic breast cancer.

Confronting Cancer as a Community

This study aims to better understand the cause of colorectal cancer and how to find the best treatment for Hispanic patients with colorectal cancer. The genetic information in the blood and tissues may explain why patients who have the same type of cancer and receive the same treatment do not always have the same results. By combining genetic (certain qualities or traits passed from parents to offspring) information with clinical data, such as the responses of different kinds of cancers to different treatments, this study could lead to more knowledge about why certain cancers occur and why they respond differently to treatments. Information gathered from this study may help researchers match treatments to the genetics of each patient and the genetic changes in their tumor. This approach is known as personalized medicine.

The Cancer Connected Access and Remote Expertise Beyond Walls Program to Provide In-Home Cancer Treatment and Improve Treatment Satisfaction in Cancer Patients Living in the Florida Panhandle and Surrounding Areas

This phase II trial studies whether providing cancer treatment in the home is preferred over the traditional clinic setting and if it improves treatment satisfaction in cancer patients living in the Florida Panhandle and surrounding areas. Typically, drug-related cancer care is provided at a medical center which causes patients to have to spend considerable time away from their family, friends, and familiar surroundings. This may add to the physical, emotional, social, and financial burden for patients and their families during this difficult time in their lives. The Cancer Connected Access and Remote Expertise (CARE) Beyond Walls (CCBW) program uses a specialized care team trained to provide cancer treatment in the patient's home setting. It is designed to support remote connection between the home health team and providers and Mayo clinic. This may be preferred over the traditional clinic setting which may improve treatment satisfaction in cancer patients living in the Florida Panhandle and surrounding areas.
