Colorectal Cancer

The purpose of this trial is to evaluate how well petosemtamab in combination with chemotherapy works against colorectal cancer that has recurred after previous treatment and that cannot be safely removed by surgery or has spread to other parts of the body. Participants will receive either petosemtamab + doctor's choice of chemotherapy (mFOLFOX6 or FOLFIRI) or doctor's choice of standard-of-care (SOC) cetuximab or bevacizumab + chemotherapy (mFOLFOX6 or FOLFIRI). No participants will be given placebo. The treatment duration will be different for every participant. If a participant's cancer stays the same or gets better, and there are not any serious problems, participants can keep getting study treatment for as long as the study is open. Participants will be asked to attend 2 visits at the study clinic for each cycle (duration of cycle is 4 weeks). During visits, there will be various tests (such as blood draws) and procedures (such as imaging) to monitor whether the study treatment is safe and effective. The overall study duration (including screening, treatment, and follow-up) will be different for every participant.

This is a Phase 1a/1b, first time in human (FTIH), open-label, dose escalation and expansion study to evaluate the safety, tolerability, and preliminary efficacy of CT-202 (study drug), a humanized T cell engaging bispecific antibody targeting nectin-4, in participants with nectin-4 expressing recurrent, unresectable or metastatic refractory/resistant TNBC, CRC, or UC. Results of the study including PK, PD, efficacy, and safety will be used in the RP2D determination.

Colorectal cancer (CRC) is the third most common type of cancer diagnosed worldwide. The purpose of this study is to assess change in disease activity when telisotuzumab adizutecan is given alone compared to standard of care (SOC) given alone. Telisotuzumab adizutecan is an investigational drug being developed for the treatment of CRC. This study will be divided into two groups called treatment arms. In arm 1 participants will receive telisotuzumab adizutecan alone. In arm 2 participants will receive SOC alone. Approximately 140 adult participants with CRC will be enrolled in the study in 45 sites worldwide. In arm 1, participants will receive intravenous (IV) doses of telisotuzumab adizutecan alone. In arm 2 Participants will receive SOC alone. The study will run for a duration of approximately 51 months. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at an approved institution (hospital or clinic). The effect of the treatment will be frequently checked by medical assessments, blood tests, questionnaires and side effects.

The study involves the planned use of a new microwave-based device during colonoscopy procedures in 50 patients to assess the performance and safety of its use for detection of colorectal polyps and lack of normal clinical practice modification. The device is a final design version, which has been previously tested in several preclinical studies (including phantom studies, an ex vivo study with human tissues, and an in vivo study with porcine model) and in a pilot study in humans (NCT05477836)

Background: Cytoreductive surgery (CRS) removes tumors in the abdomen. HIPEC is hyperthermic (heated) chemotherapy that washes the inside of the abdomen. CRS with HIPEC may help people with peritoneal carcinomatosis. These are tumors that have spread to the lining of the abdomen from other cancers. Researchers think they can improve the results of CRS with HIPEC treatment on these tumors by choosing the chemotherapy drugs used in HIPEC. Objective: To see if HIPEC after CRS can be improved, using either a model called the SMART (Sustained Microenvironment for Analysis of Resected Tissue) System or using 3-D cell culture (organoid) models, in order to test different chemotherapy drugs on tumors that were surgically removed prior to HIPEC treatment (these models are not attached to the body) versus tumors that were treated with HIPEC while still inside the body before being immediately surgically removed. Eligibility: Adults ages 18 and older who have peritoneal carcinomatosis that cannot be fully removed safely with surgery. Design: Participants will be screened with: Medical history Physical exam Blood and urine tests Electrocardiogram (EKG) Computed tomography (CT) scan Other imaging scans, as needed Tumor biopsy, if needed Laparoscopy (small cuts are made in the abdomen, and a tube with a light and a camera is used to see the organs in the abdomen), if needed Participants will enroll in NIH protocol #13C0176. This allows their tumor samples to be used in future research. Some screening tests may be repeated in the study. Participants will have CRS. As many of their visible tumors will be removed as possible during surgery except for a few specific tumors left to receive the HIPEC treatment. Then they will receive HIPEC and the remaining tumors will be immediately removed. Participants will be in the hospital for 7-21 days after this surgery (CRS with HIPEC). Participants will give tumor, fluid samples (from the abdomen during surgery), blood, saliva, cheek swab, and stool for research. They will complete surveys about their health and quality of life. Participants with peritoneal mesothelioma (mesothelioma primary only) will have genetic (DNA) testing to determine clinical (CLIA level) germline BAP1 status for research use. Participants will have follow-up visits for up to 5 years from CRS with HIPEC. If there is disease progression, participants may have CRS with HIPEC again. Participants will then have follow-up visits for up to 5 years from the date of last CRS with HIPEC.

Patients with resectable solid primary cancers and even limited number of metastases are potentially curable. However, most patients develop recurrences despite surgery. Also, early detection of lung cancer with low dose CT screening may cure patients at an early stage. Circulating and disseminated tumor cell (CTC/DTC) and circulating cell-free (cf) DNA isolation from the blood, urine and bone marrow will increase understanding of cancer spread and advance knowledge to develop individualized therapies and improve screening.

Background: The National Cancer Institute Surgery Branch (NCI-SB) has developed experimental therapies that involve taking white blood cells from patients' tumor or from their blood, growing them in the laboratory in large numbers, and then giving the cells back to the patient. Objective: This study will allow patients to under screening and evaluation for participation in NC-SB Protocols. Eligibility: Patients 18 years or older must meet the minimum eligibility criteria for an NCI-SB treatment protocol. Design Patients will undergo testing and evaluations as required by the appropriate NCI-SB treatment protocol.

The goal of this clinical trial is to determine if FOG-001 is safe and effective in participants with locally advanced or metastatic solid tumors or in participants with familial adenomatous polyposis (FAP).

This study will examine the association between low muscle mass (myopenia) at diagnosis and chemotherapy toxicity in older adults with newly diagnosed advanced colorectal cancer.

Colorectal cancer (CRC) is the third most common type of cancer diagnosed worldwide. The purpose of this study is to assess the adverse events and change in disease activity of telisotuzumab adizutecan plus bevacizumab compared to standard of care (SOC) of LONSURF (trifluridine and tipiracil) plus bevacizumab in adult participants with refractory metastatic colorectal cancer (mCRC). Telisotuzumab adizutecan is an investigational drug being developed for the treatment of CRC. Participants will then be randomized into 2 groups called treatment arms. One group will receive telisotuzumab adizutecan with bevacizumab in different doses. Another group will receive standard of care (SOC), trifluridine and tipiracil (LONSURF), with Bevacizumab. Up to approximately 990 adult participants with refractory mCRC, will be enrolled in the study in approximately 125 sites globally. In this Phase 3, one of two groups will receive doses of Intravenous (IV) telisotuzumab adizutecan + bevacizumab and other group will receive oral SOC of trifluridine/tipiracil (LONSURF)+ Intravenous (IV) bevacizumab. The study will run for a duration of approximately of 36 months. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at an approved institution (hospital or clinic). The effect of the treatment will be frequently checked by medical assessments, blood tests, questionnaires and side effects.

Robotic-assisted surgeries are especially valuable for colorectal pathologies because they offer better vision and control for surgical manipulation given the narrow operative region within the pelvis .Some of the iatrogenic risk factors associated with higher post-operative adverse events following colorectal surgeries are surgeon experience' and hospital case load'. In order to mitigate these factors, surgical staplers have gained preference amongst surgeons due to their reproducible results and ease of learning At present there are only two methods of creating an anastomosis: hand-sewn technique using sutures or surgical staplers. Surgical staplers have been shown to be as effective as hand-sewn techniques for colorectal anastomoses However, anastomotic strictures can be bothersome for patients and the rate of stricture is fourfold higher for stapled anastomoses than for those that are hand sewn in colorectal anastomoses . Additionally, overzealous or incorrect stapling could also result in hemostasis or ischemia One of the most dreaded adverse events of colorectal resection is anastomotic leakages followed, in decreasing severity, by post-operative bleeding and ileus. Because of the severity of adverse events associated with an anastomotic leak, it is important to detect it early and provide early management for the same. However, diagnosis of anastomotic leakage is commonly a symptomatic diagnosis based on development of gas, purulent or fecal discharge from the drain, purulent discharge from the rectum, pelvic abscess or peritonitis. Such severe symptoms further complicate the post-operative recovery and lengthen the hospital stay. Interestingly, it has been reported that anastomotic leaks were more often diagnosed late in the postoperative period and more often after hospital discharge, or 12 days postoperatively . Anastomotic leakage rates vary from the colon to the rectum, with much higher rates in the rectum. Because of the severity of adverse events associate with an anastomotic leak, there is a pressing need for new techniques for prevention of anastomotic leakages .

Phase I/IIa image-guided, alpha-particle therapy study of \[203Pb\]Pb-PSV359 and \[212Pb\]Pb-PSV359 in patients with solid tumors that are known to be Fibroblast Activation Protein (FAP)-positive.

Researchers want to learn if sacituzumab tirumotecan (MK-2870) alone or with other treatments can treat certain gastrointestinal (GI) cancers. The GI cancers being studied are either advanced (the cancer has spread to other parts of the body), or unresectable (the cancer cannot be removed with surgery). The goals of this study are to learn: * About the safety of sacituzumab tirumotecan alone or with other treatments and if people tolerate it * How many people have the cancer respond (get smaller or go away) to treatment

The investigational drug to be studied in this protocol, BCA101, is a first-in-class compound that targets both EGFR with TGFβ. Based on preclinical data, this bifunctional antibody may exert synergistic activity in patients with EGFR-driven tumors.

This study will assess whether methylene blue fluorescence imaging can help surgeons identify the ureters during colorectal surgery. Methylene blue, given through a vein during the operation, is taken up and excreted by the kidneys, allowing the ureters to appear under a special fluorescence camera system. The study will include adults undergoing open, laparoscopic, or robotic colorectal surgery at Prince of Wales Hospital. The surgeons will compare ureter visibility using standard white light with visibility using fluorescence imaging at different stages of the operation. The study will also assess the best dose of methylene blue, the additional time required, the ease of using the imaging system, and whether the imaging findings affect the surgical plan. The study's hypothesis is that methylene blue fluorescence imaging will make it easier or faster to identify the ureters than white light alone. The technique will be considered feasible if it is helpful in at least 20% of operations-for example, by identifying a ureter earlier or identifying it when it cannot be seen under white light. The findings will help determine whether a larger future study should be conducted.

This is a Phase 1, multicenter, open-label study of DISP-10, a combination therapy consisting of DV-10 (adenovirus) and idecabtagene vicleucel (ide-cel, BCMA-directed chimeric antigen receptor \[CAR\] T), in adult participants with advanced gastrointestinal (GI) cancers. The study will consist of 2 parts: dose-escalation (Part 1) and dose-expansion (Part 2). Part 1 of the study will evaluate the safety and tolerability of increasing dose levels of DISP-10 to establish the recommended dose for expansion (RDE); Part 2 will evaluate the safety and efficacy of DISP-10 in participants treated at the RDE.

This study is a pilot feasibility randomized trial involving newly diagnosed colorectal cancer (CRC) patients who identify as Latinx. The study aims to leverage existing academic-community partnerships in Santa Clara County to develop and evaluate a multi-level community health worker/promotora (CHW/P) navigator intervention. If found effective, APOYO has the potential to affect clinical outcomes for Latinx colorectal cancer patients both directly and indirectly, including improving health-related quality of life, health care utilization, and reducing social needs.

The purpose of this study is to look at mental health services for adults with depressed mood who were diagnosed with cancer at the age of 65 or older. This study will compare the usual approach for connecting older adults with depressed mood to mental health services with the Open Door for Cancer (OD-C) approach. We will find out if the OD-C approach is practical and useful for cancer patients who participate in the intervention and for providers who see or treat cancer patients.

Genetic testing is a type of test that detects changes to the genes-the DNA instructions that are passed on from the mother and father. The results of a genetic test can confirm whether the participant has a genetic disorder, which is a disease caused in whole or in part by changes to the genes. Genetic testing can also help determine a person's chance of getting or passing on a genetic disorder. Genetic tests use a sample of blood, hair, skin, or other tissue, and they can look at one gene or multiple genes at the same time. Genetic testing may change the options for treating people with certain types of cancer. For example, some medications are more helpful for the treatment of cancer in people with certain gene changes (mutations). The researchers are doing this study to develop new educational materials about genetic testing for people who speak different languages and have diverse cultural and educational backgrounds. During the study, the staff will interview participants with diverse cultural and educational backgrounds and ask them to review a sample of the educational materials that have been developed so far. Participants will give their opinions on these materials, and the researchers will use participants' feedback to improve the materials.

The Phase 2 monotherapy portion of this study is currently enrolling and will evaluate the efficacy and safety of PC14586 (INN rezatapopt) in participants with locally advanced or metastatic solid tumors harboring a TP53 Y220C mutation. The Phase 1 portion of the study will assess the safety, tolerability and preliminary efficacy of multiple dose levels of rezatapopt as monotherapy and in Phase 1b in combination with pembrolizumab.

The purpose of this study is find out whether the combination of trastuzumab deruxtecan (T-DXd) and cetuximab is an effective treatment for participants with metastatic and/or unresectable colorectal cancer that expresses low levels of HER2 and that has gotten worse after receiving standard treatment.

This is a randomized, double-blind, phase III clinical trial. The study aims to demonstrate that the treatment regimen of Enlituo® plus FOLFOX is equivalent to that of Erbitux® plus FOLFOX in participants with RAS/BRAF wild-type and MSS/pMMR locally advanced/metastatic colorectal cancer. Enrolled participants will be stratified according to ECOG performance status (0 vs. 1) and primary tumor location (left-sided or right-sided colon) and randomly assigned in a 1:1 ratio to either the experimental group (Enlituo® + FOLFOX) or the control group (Erbitux® + FOLFOX). Participants will: * Receive Enlituo®/Erbitux®: 500 mg/m², administered via intravenous infusion over a minimum of 120 minutes, once every two weeks. * Receive FOLFOX * Participants in the Erbitux® plus FOLFOX group who achieve CR, PR, or SD at 16 weeks will cross over to receive Enlituo® plus FOLFOX. * Be recommended to undergo efficacy assessments every 8 weeks (±7 days). * Comply with the blood sample collection procedures for pharmacokinetic (PK) and immunogenicity analyses. * Be required to provide baseline tumor biopsy specimens or 8-10 unstained slides of archived tumor tissue (formalin-fixed, paraffin-embedded) from within the past 3 years. The Blinded Independent Central Review (BIRC) will assess: * Objective Response Rate (ORR) within 16 weeks. * Disease Control Rate (DCR) within 16 weeks. * Duration of Response (DoR). * Progression-Free Survival (PFS). The investigators will assess: * ORR within 16 weeks. * DCR within 16 weeks. * DoR. * PFS. * Overall Survival (OS). * Safety: Incidence and severity of adverse events (AEs) and serious adverse events (SAEs), as well as findings from laboratory tests, vital signs, and physical examinations. * Dose intensity, and incidence of dose interruptions, dose reductions, and treatment discontinuations due to AEs.
