Peritoneal Carcinoma

The goal of this clinical trial is to learn if paricalcitol or pirfenidone can help make tumors removable by surgery in adults with peritoneal cancer who are currently unable to have their tumor removed. The study aims to answer are whether paricalcitol or pirfenidone improve tumor response and tissue healing after 12 weeks of treatment, and which of these two drugs is more effective at helping participants become eligible for surgery. Researchers will compare paricalcitol to pirfenidone to see which drug works better and has a manageable safety profile. Participants will take either paricalcitol or pirfenidone by mouth every day for 12 weeks while continuing their standard chemotherapy, visit the clinic regularly for checkups and lab tests, keep a daily diary to track their study medication, and undergo a surgical re-evaluation after treatment to see if their tumor can be removed.

This is an open-label, Phase 1 clinical study to evaluate the safety, tolerability, PK profiles, and clinical activity of IV and PO arginine supplementation + SOC chemoimmunotherapy regimens in participants with PROC.

Participants will be scheduled for primary cytoreductive surgery as part of their standard care. Before surgery, participants will be assigned by chance to a study group. Depending on which group they are in, they will receive either acute normovolemic hemodilution/ANH during surgery or standard surgical management during surgery. The researchers think acute normovolemic hemodilution/ANH may decrease the need for allogenic blood transfusion/ABT in people having primary cytoreductive surgery.

To determine the incidence and risk factors in the development of ovarian, fallopian tube, and peritoneal cancers in Japanese women carrying Breast Cancer Susceptibility Gene (BRCA)1/2 variants.

This research study aims to evaluate the safety and determine the optimal dose of a new experimental drug, vvDD-hIL2 (vaccinia virus double-deleted human interleukin 2), in patients with advanced abdominal cancer. The study will involve three dose levels, with three to six patients enrolled at each level. vvDD-hIL2 is a genetically modified vaccinia virus, derived from the virus previously used for smallpox vaccination. The modification is intended to target and destroy tumors while minimizing harm to healthy tissues by stimulating the body's immune response. Participants will receive an injection of vvDD-hIL2 directly into their abdominal tumors at AHN West Penn. The study team will monitor for side effects and assess tumor response to the treatment. Active participation will last up to two months, involving seven clinic visits and approximately four lab visits at AHN West Penn Hospital. Visits will include standard of care procedures as well as study-specific tests and exams. Most visits will last one to two hours, with some extending to two to three hours. The drug administration day will require a twelve-hour visit. Effectiveness and side effects will be evaluated through blood draws, oral swabs, urinalysis and tissue biopsies. Tissue samples will be used for genomic analysis and stored for potential future research. Data collected may also be used for future research purposes. Previous human trials of vvDD-hIL2 have reported side effects such as pain, rash or inflammation at the injection site, low-grade fevers, flu-like symptoms, and fatigue. There is a rare risk of rash transmission to close contacts with skin openings, and information on limiting contact and managing rash development will be provided.

This study is an open-label, dose-escalation, investigator-initiated phase I interventional clinical study. To evaluate the safety, tolerability and preliminary efficacy of SCT-001 CAR-T cell injection in subjects with relapsed and refractory epithelial ovarian, fallopian tube and peritoneal cancer, and to explore the pharmacokinetic characteristics, biomarker changes and immunogenicity of SCT-001 CAR-T cell injection in subjects with relapsed and refractory epithelial ovarian, fallopian tube and peritoneal cancer. In this study, two trial cohorts were set up, cohort 1 was the intraperitoneal route of administration, and the subjects enrolled in cohort 1 needed to meet the conditions for intraperitoneal administration ((1) the subject had a large amount of ascites, (2) the subject was suitable for peritoneal catheterization, (3) the subject had no severe abdominal adhesions, and (4) the subject agreed to undergo intraperitoneal surgical catheterization for intraperitoneal administration); Cohort 2 is the intravenous route.

Colorectal cancer (CRC) is the 3rd most common cancer in France. Treatment of CRC relies primarily on surgical removal of the primary tumor and chemotherapy is the current standard of care for synchronous metastatic disease. Overall survival remains strongly correlated with the tumor stage at the time of surgery, from 90% at five years for localized disease (stages 1 and 2), to around 20% for metastatic forms of the disease (stage 4). Recent research in cancer highlights the role of the immune system in the development, evolution and fate of tumors. Understanding the nature of interactions between different immune cells infiltrating the tumor is important for the development of innovative therapies. Recently, the consensus molecular classification of CRC confirmed the importance of the immune response in CRC by showing that a "high immune response" is a good prognostic indicator for patients with this pathology. However, immunotherapies are effective for only a minority of patients with metastatic CRC. Indeed, anti Programmed cell Death 1 (anti-PD-1), -PD-L1 immune checkpoint blocking antibodies have only shown effectiveness in patients with microsatellite instability (MSI), which only represents 5% of metastatic CRCs. Thus, the aim of this study is to better understand the role of the immune system on the development of CRC and its possible modulation to treat or prevent metastatic recurrences.

To prospectively assess the incidence of peritoneal carcinomatosis for women with isolated STIC (serous tubal intraepithelial carcinoma). Moreover, to identify histopathological characteristics of STIC which are reproducible and associated to the risk of peritoneal carcinomatosis and to report the findings of additional diagnostics.
