Symbiotic-GI-03: A Study to Learn About the Study Medicine Called PF-08634404 in Combination With Chemotherapy in Adult Participants With Metastatic Colorectal Cancer

The purpose of this study is to learn more about a new medicine called PF-08634404, and how well it works in people with cancer of the colon or rectum (CRC)). The goal is to understand if the new study medicine, combined with chemotherapy that is approved for colorectal cancer, can help people whose cancer has spread or returned after treatments taken before. To join the study, participants must meet the following conditions: * Be 18 years or older. * Have colorectal cancer that has spread to other parts of your body. * Be in good enough health to receive study treatment. * Should not be pregnant before starting treatment. Participants will be randomized (like flipping a coin) to one of 2 different treatment arms. The first arm (Arm A) will include the new medicine PF-08634404 in combination with chemotherapy that is approved for colorectal cancer, and the second arm (Arm B) will include an approved medicine for colorectal cancer, called Bevacizumab, in combination with chemotherapy that is approved for this type of cancer. Participants and their doctors will not know which arm they are being assigned to. Participants will receive all the study medications through intravenous (IV) infusions, which means the medicine is given directly into a vein. The treatment will be given in cycles, and participants may continue receiving it if it is helping and they are not experiencing serious side effects. The medicine will be given at a clinical site, where trained medical staff will check participants during and after each treatment. * The study is expected to last approximately 33 months for each participant. * Participants will have regular visits to the study site for treatment, health checks, and tests. * After stopping treatment, participants will return for a final visit about 30 to37 days later to check their health and review any side effects. * Follow-up will continue every 12 weeks by phone or in person or by reviewing health records to check on health status and any new treatments.

A Study of IDRX-42 (GSK6042981) Versus (vs) Sunitinib in Participants With Gastrointestinal Stromal Tumors After Imatinib Therapy

The purpose of this study is to find out if a new drug, called IDRX-42 (also known as GSK6042981), is effective in treating adults with a type of cancer called Gastrointestinal Stromal Tumors (GIST) when compared to another drug named sunitinib. The study will see if IDRX-42 works well and is safe for participants whose GIST has spread or cannot be surgically removed, and who have already taken the drug imatinib.

Virtual Reality for GI Cancer Pain to Improve Patient Reported Outcomes

Patients with digestive tract malignancy often experience severe and unremitting abdominal pain that negatively affects physical, emotional, and social function, as well as health related quality of life (HRQOL). Therapeutic virtual reality (VR) has emerged as a promising and evidence-based treatment modality for cancer pain. Users of VR wear a pair of goggles with a close-proximity screen in front of the eyes that creates a sensation of being transported into lifelike, three-dimensional worlds. To date, VR has been limited to short-term clinical trials for cancer pain. Moreover, limited research exists on theory-based VR modalities beyond mere distraction, such as VR that employs acceptance and commitment therapy (ACT) with components of biofeedback and mindfulness. To bridge these gaps, this study seeks to: (1) assess the impact of immersive VR on patient-reported outcomes (PROs), including pain, activity metrics, and opioid use among patients with visceral pain from a digestive tract malignancy; (2) assess differences in PROs, activity metrics, and opioid use between skills-based VR therapy vs. distraction VR therapy; and (3) determine patient-level predictors of VR treatment response in visceral cancer pain. To address these aims, the study will measure PROs and opioid use in 360 patients randomized among 3 groups and follow them for 60 days after enrollment: (1) an enhanced VR group receiving skills-based VR; (2) a distraction-based VR group receiving patient-selected VR videos; and (3) a VR sham control group using a VR headset with 2-D content. The results will inform best practices for the implementation of VR for visceral cancer pain management and guide selection of patient-tailored experiences.

Impact of Oral Versus Intravenous 5-FU-Based Adjuvant Regimens on Sleep Quality and Depression in Patients With Gastrointestinal Cancers

This prospective, non-randomized, single-center observational study is designed to investigate the effects of oral versus intravenous (IV) 5-fluorouracil (5-FU)-based adjuvant chemotherapy regimens on sleep quality and depression levels in patients with non-metastatic gastrointestinal system (GIS) cancers. Eligible adult patients (aged 18 years or older) who are scheduled to receive adjuvant chemotherapy at the Ankara Etlik City Hospital Medical Oncology Department will be assessed using the Pittsburgh Sleep Quality Index (PSQI) and the Beck Depression Inventory (BDI). These evaluations will be conducted at baseline (prior to chemotherapy), on day forty-five, and on day ninety of treatment. This study will not interfere with standard oncologic care. Instead, sleep disturbances and depressive symptoms will be monitored during routine clinical follow-up. Patients identified with significant psychological distress will be referred to psychiatry or sleep medicine departments for further evaluation. The results of this study may provide insights into how different routes of 5-FU administration impact patients' mental health and quality of life, potentially informing future supportive care strategies during adjuvant chemotherapy.

Immune Checkpoint Inhibitor (ICI)-Drug-Drug Interaction (DDI) Study

Immune checkpoint inhibitors (ICIs) (also called "immunotherapy") are an effective family of anti-cancer drugs, but they can cause serious side effects. Some evidence suggests these side effects might happen because ICIs interact with other drugs that you may already be taking, making those drugs work differently, or causing more side effects. The purpose of this study is to see whether ICIs impact how the liver processes other drugs. To do this, participants will be given a probe cocktail of 7 different FDA-approved drugs that are processed in different ways in the liver.

PPG vs. ICG in Gastrointestinal Resections

This randomized controlled trial compares a novel optical technique against the standard of care for assessing tissue perfusion in gastrointestinal surgery. Participants are randomized to receive either intraoperative imaging photoplethysmography (iPPG) or indocyanine green (ICG) fluorescence imaging. In the ICG group, the fluorescence data are comprehensively analyzed in two distinct ways: (1) Qualitative Assessment: real-time visual interpretation of the angiogram flow by the operating surgeon; and (2) Quantitative Assessment: software-based analysis of fluorescence kinetics (e.g., time-to-peak, maximum intensity) to generate objective perfusion parameters. The study aims to determine the agreement between the iPPG-based evaluations and both the qualitative and quantitative dimensions of the ICG standard.
