Maytansinoid DM4-Conjugated Humanized Monoclonal Antibody huC242 in Treating Patients With Solid Tumors

RATIONALE: Monoclonal antibodies, such as maytansinoid DM4-conjugated humanized monoclonal antibody huC242, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them.

PURPOSE: This phase I trial is studying the side effects and best dose of maytansinoid DM4-conjugated humanized monoclonal antibody huC242 in treating patients with solid tumors that cannot be removed by surgery or have spread to other parts of the body.

Neoantigen-Targeted Vaccine Combined With Anti-PD-1 Antibody for Patients With Stage IV MMR-p Colon and Pancreatic Ductal Cancer

Phase 1 study evaluating feasibility, safety, and immune response to a personalized neoantigen vaccine combined with retifanlimab for MMR-p mCRC and mPDAC patients with measurable disease following first-line FOLFIRINOX/FOLFOXIRI (FFX).

Efficacy and Safety of mFOLFIRINOX as Postoperative Chemotherapy for Pancreatic Cancer in Chinese Patients.

This prospective and open-label study evaluates the efficacy and safety of mFOLFIRINOX as postoperative chemotherapy in treating Chinese patients with pancreatic cancer after R0/R1 resection.

Neoantigen Peptide Vaccine Strategy in Pancreatic Cancer Patients Following Surgical Resection and Adjuvant Chemotherapy

This is a phase 1 open-label study to evaluate the safety and immunogenicity of a neoantigen peptide vaccine strategy in pancreatic cancer patients following surgical resection and adjuvant chemotherapy. The neoantigen peptide vaccines will incorporate prioritized neoantigens and personalized mesothelin epitopes and will be co-administered with poly-ICLC. The hypothesis of this study is that neoantigen peptide vaccines will be safe and capable of generating measurable neoantigen-specific CD4 and CD8 T cell responses.

Tislelizumab Combined With Nab-paclitaxel and Gemcitabine for Recurrent Pancreatic Cancer

To evaluate the efficacy of Tislelizumab combined with Nab-paclitaxel and Gemcitabine in the treatment of recurrent pancreatic cancer

Project CADENCE (CAncer Detected Early caN be CurEd)

With existing evidence showing the difference in miRNA expression levels between non-cancer and cancer groups, the investigators assume that levels of DNA methylation, RNA expression as well as protein concentration will also be dysregulated during disease progression. Combining the power of multi-omic cancer biomarkers, the investigators hypothesize that the sensitivity and specificity of MiRXES MCST can be significantly improved compared to existing multi-cancer diagnostic tests.

In this study, the investigators propose to develop and validate blood-based, multi-cancer screening tests through a multi-omics approach.

Intra-luminal Radiofrequency Ablation for Inoperable Malignant Biliary Stenosis

Only a small proportion of patients with biliary obstruction caused by hepatopancreatobiliary malignancies are suitable for surgical resection. Therefore, most patients with malignant biliary obstruction will need palliation of their obstructive jaundice to relieve the symptoms and prevent life threatening complications such as biliary sepsis. The endoscopic or percutaneous/transhepatic routes, such as endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous transhepatic cholangiography (PTC), and stents are accepted approaches for the relief of jaundice in malignant biliary obstruction. Improvement in the bilirubin level is also essential before palliative chemotherapy is considered in these patients. However, tumor ingrowth still remains a major cause of obstruction. In this trial, the investigators will use HabibTM EndoHPB (EMcision Ltd., UK) catheter which was used for the endobiliary radiofrequency ablation (RFA) treatment as a form of neoadjuvant therapy in hepatopancreatobiliary adenocarcinoma.

Effectiveness Validation of CELBREA® in Symptomatic Women or With Diagnostic Doubt of Breast Pathology (DETECT-BH)

This is an observational, prospective, and transversal study, designed to evaluate the effectiveness of CELBREA® in women from the local community coming to consult at the Breast Pathology Unit of La Paz Hospital (Madrid, Spain), because of discomfort, breast symptoms, or because they have been sent for specialized evaluation because of a diagnostic doubt, providing actualized data on the effectiveness of the device within the context of the real-world scenario. Because of its transverse nature, the observation period will be limited to the necessary amount of time to perform the initial consult, additional tests when prescribed by the physician, and the CELBREA® test.

Treatment of the Pancreatic Stump With Neoprene®-Based Glue After High-risk Pancreatoduodenectomy

The study evaluates the safety and efficacy of Neoprene-based glue in the management of pancreatic stump after pancreatoduodenectomy (PD) in patients at high risk for pancreatic fistula and early neoplastic recurrence, compared with a population of patients at conventional risk.

Prospective Monocentric Clinical-biological Database

Pancreatic adenocarcinoma (PA) is a solid cancer with a very poor prognosis with overall survival, all stages combined, not exceeding 5% at 5 years. The incidence and number of deaths caused by this type of tumor have been steadily increasing for two decades. In the absence of therapeutic advances, PA will be one of the leading causes of cancer deaths in 2030.

In recent years, researchers and clinicians have now attempted to characterize and understand PA as a whole, through the various stages of its carcinogenesis and the analysis of its microenvironment. Indeed, the stroma of PA can represent up to 80% of the tumor mass and mainly composed of activated fibroblasts (CAF), endothelial and immune cells and extracellular matrix (collagen and fibronectin). However, the characterization of cell subtypes of this stroma is under study, as the pro or anti-tumor role of each cell subtype is not yet well understood.

New technologies such as the CyTOF that has just been acquired by the ICM and the IRCM will make it possible to study these problems and to examine the cellular subpopulations that make up the tumor. On the other hand, active research is conducted to disrupt the dialogue between the tumor cells and those of the microenvironment.

The search for innovative treatments in pancreatic adenocarcinoma requires the use of models of relevant preclinical studies. The most widely used models are based on cell lines of human origin used in vitro or in vivo after xenograft in immunodeficient mice. In particular, studies with pancreatic adenocarcinomas (PDX) derived tumors of patients reported that the response rate of PDX to certain drugs (gemcitabine, erlotinib …) used clinically was similar to the response rates of patients enrolled in clinical studies. of these agents as monotherapy. A number of studies have evaluated the efficacy of targeted anti-tumor, anti-angiogenic or anti-stroma therapies from these PDTX models. Personalized medicine strategies can be envisioned as well as the study of new biomarkers, drugs or molecular mechanisms involved in therapeutic resistance. For several years, the investigators have been developing AP PTDX in the INSERM 1194 unit.

The investigators propose to continue the development of this collection of pancreatic adenocarcinoma PDTX prospectively and to carry out their histological, molecular and mutational characterization.
