This is a randomized, open label, single-center, phase 2, randomized controlled trial of sequential cytoreductive intervention versus standard of care therapy for patients with intervenable oligometastatic (stage IV) cancer of the upper gastrointestinal (GI) tract and undetectable ctDNA at the time of randomization after a three-month induction chemotherapy period.
NCT04331041
Patients with advanced pancreas adenocarcinoma will be randomized on a 6:1 basis to receive standard of care chemotherapy followed by adaptive stereotactic body radiotherapy (SBRT) with concurrent and adjuvant FAK inhibitor defactinib (experimental arm) or standard of care chemotherapy followed by SBRT (control arm). Patients enrolled to the experimental arm will be assessed for clinical outcomes such as progression free survival (PFS), local control, distant control, and toxicity. The initial 6 patients randomized to the experimental arm will be considered the safety lead-in and will be assessed for dose-limiting toxicities (DLTs). Following completion of the safety lead-in, additional patients will be accrued in order to reach a total of 36 patients on the experimental arm (inclusive of the safety lead-in cohort) and 6 on the control arm.
NCT05825066
The objective of this research is to find out what effects (good and bad), the sequence of Gemcitabine - Abraxane (nab-Paclitaxel) followed by mFOLFIRINOX, the standard chemotherapy for pancreatic cancer, has on participants and their condition. Gemcitabine - Abraxane (nab-Paclitaxel) and mFOLFIRINOX has been approved by the US Food and Drug Administration (FDA) as first line treatment for advanced pancreatic cancer. The sequence of Gemcitabine - Abraxane (nab-Paclitaxel) followed by mFOLFIRINOX has not been approved by the FDA for treatment of pancreatic cancer.

Pancreatic adenocarcinoma (PA) is the most common tumor of the pancreas. Given its poor prognosis and the major therapeutic consequences, the discrimination between PA and other pancreatic solid lesions is mandatory. Endoscopic ultrasound (EUS) is admitted as the most sensitive imaging procedure for the detection and characterization of pancreatic tumors. Over the past 30 years, EUS-guided tissue acquisition (EUS-TA), or more recently fine needle biopsy (EUS-FNB), has demonstrated its efficiency for tissue sampling and remains the gold standard for the pathologic diagnosis of pancreatic lesions. The assessment of pancreatic tumor enhancement using ultrasound contrast agents (UCAs) in real time with imaging specific methods seems useful to improve their characterization either by contrast-enhanced EUS (CE-EUS) or, more recently, by contrast-harmonic EUS (CH-EUS). CH-EUS was already demonstrated useful to differentiate pancreatic adenocarcinoma from other pancreatic lesions. EUS-Elastography (EUS-E) is another EUS image enhancement technique, which rational based on the difference in elasticity between the tissues. There are two types of elastographies: strain elastography (SE) and shear wave elastography (SWE). SE has proved useful for the characterization of pancreatic lesions and lymph nodes. However, this technique was demonstrated difficult to perform with adequate accuracy and reproducibility for pancreatic lesions and have many limitations. In some recent publications SWE was demonstrated moderate reliability. Pancreatic neuroendocrine tumors (pNETs) are rare tumors, but according to the last epidemiological data, their incidence and prevalence are steadily rising. Surgical resection is generally performed for pNETs due to their malignant potential. However, with increasing use of high-resolution conventional imaging, the significant incidence of small (≤ 2 cm) pancreatic neuroendocrine incidentaloma (pNET) has risen in recent decades. EUS is recognized as the most sensitive procedure for the detection and characterization of pNETs. Overall sensitivity of EUS-TA for the diagnosis of pNETs is high, reaching 95.1% in recently published study, appearing higher in small lesions (≤ 20 mm) than in large lesions (\> 20 mm). The overall concordance rate for EUS-TA and surgical specimens grading varies from 58% to 86.4% and is higher for lesions ≤ 10 mm, 10-20 mm, comparing to lesions \> 20 mm. These results confirm the risk of under or over-grading of pNETs on the EUS-TA specimen, independently of the needle size which used for the TA. CH-EUS was also demonstrated accurate in the prediction of pNETs malignancy and useful for decision-making management of these tumors. Hypothesis Two new image enhancement EUS technologies were recently developed, able to assess precisely tumor microvascular density and the stiffness of pancreatic lesions, that is correlated to tumor's stroma fibrosis, and thus help to characterize and predict the malignancy, and accordingly, the management of the pancreatic solid lesions. It's particularly useful in overcoming EUS false-negative cases of PA and small pNETs malignancy diagnosis. Superb Microvascular Imaging (SMI) is a novel doppler technique that enhances the range of visible blood flow, by revealing low velocity microvascular flow, enabling the capture of a higher-quality microvascular flow images. Based on the same principle as CH-EUS, which assesses tumor microvascularization, this technique is expected to be also useful for the PSLs malignancy diagnosis. Shear Wave Elastography (SWE) relies on the properties of shear-wave propagation to offer an advanced assessment of their velocity

Few chemotherapeutic options exist for pancreatic cancer. Moreover, objective criteria are lacking for deciding which regimen is more beneficial for patient presenting with metastases at diagnosis. This study investigates whether organoid generation from tumour samples of pancreatic cancer is a safe and feasible process for testing of multiple chemotherapy regimens in the laboratory. By participating to this study, patients will have a part of the tumour tissue retrieved and sent to the laboratory for organoid generation and drug testing. For surgically-resectable tumors, tumoral tissue samples will be collected from the main surgical specimens, before sending it for final pathological examination. In case of suspected metastatic lesion at diagnosis, curative surgery is not indicated. Therefore, we will offer patients to undergo port-a-cath implantation for chemotherapy delivery and concomitant laparoscopic surgical excisional biopsy of suspicious metastatic (either hepatic or peritoneal) lesions. At this stage of the study, the treatment that the patient will receive after surgery will not be affected by the results of the laboratory testing. In fact, all patients will receive the standard of care treatment based on the most recent oncologic guidelines and on the oncologist's clinical judgement. As part of the study, each patient will be followed for 30 days to assess possible surgical complications related to the surgical biopsy. This study will help to speed up the implementation of organoid generation in the clinical routine for the choice of the best treatment of patients affected by pancreatic cancer.

This study is for verification of predictive biomarkers for pancreatic cancer treatment using multi-center liquid biopsy.
NCT06315439
Endoscopic ultrasound-guided (EUS) tissue acquisition is the current standard of care for the diagnosis of pancreatic solid lesions but it is burdened by a non-negligible risk of non-diagnostic or inconclusive results. Ex-vivo fluorescence confocal laser microscopy (FCM) with MAVIG VivaScope® 2500M-G4 could allow real time assessment of adequacy and diagnosis of the sample.
NCT06090318
This is an open-label, single-arm, Phase 1b/2 study designed to evaluate the safety, tolerability, and preliminary efficacy of milademetan in combination with atezolizumab in patients with advanced solid tumors with confirmed homozygous CDKN2A loss and WT TP53 who have progressed on or are refractory to prior PD-1/PD-L1 inhibitor therapy and who, in the opinion of the Investigator, are unlikely to tolerate or derive clinically meaningful benefit from other therapy. This study will determine the recommended dose of milademetan when given in combination with atezolizumab (the combination RP2D) using a dose de-escalation safety assessment cohort (Phase 1b). Following identification of the combination RP2D, the safety profile and preliminary anti-tumor activity of the combination RP2D will be evaluated in a larger population in a dose expansion cohort (Phase 2).
