Mismatch Repair Deficiency

The PICC-3 study is a multicentre, single-arm, phase II trial evaluating toripalimab plus celecoxib in patients with mismatch repair-deficient (dMMR) or microsatellite instability-high (MSI-H) locally advanced colorectal cancer. The trial uses a response-adapted treatment strategy, whereby patients with clinical complete response (cCR) after therapy may enter a non-operative management pathway, while patients without cCR proceed to surgery. Response assessment is based on imaging, endoscopy, biopsy evaluation, and ctDNA analysis.

This study is an open-label Phase Ib (Part A) dose escalation followed by a blinded, randomized, multi cohort Phase 2a (Part B) comparison of combination vs. reference regimens. Currently study will only be enrolling the Phase 1b and the Phase 2a protocol requirements will be added to the study near completion of the Phase 1b

This is an multicenter study that will test the diagnostic accuracy of a blood test (i.e., a liquid biopsy) for the diagnosis of colorectal cancer (CRC), advanced adenomas (AAs), as well as Lynch-syndrome associated cancers. Additionally, a pre-planned analysis will evaluate the use of this liquid biopsy as a tool for molecular residual disease monitoring purposes.

Efficacy evaluate of iparomlimab and tuvonralimab (a PD-1/CTLA-4 bispecific antibody) in patients with surgically resectable dMMR endometrial cancer.

International registry for cancer patients evaluating the feasibility and clinical utility of an Artificial Intelligence-based precision oncology clinical trial matching tool, powered by a virtual tumor boards (VTB) program, and its clinical impact on pts with advanced cancer to facilitate clinical trial enrollment (CTE), as well as the financial impact, and potential outcomes of the intervention.

Due to dMMR colon cancer patients respond poorly to conventional chemotherapy, but immunotherapy can significantly improve the pCR in this group of patients, this study intends to explore whether neoadjuvant immunotherapy can improve the R0 resection rate with preservation of adjacent organs in T4 colon cancer patients with dMMR.

The objective of this study was to investigate the feasibility of a PD-1 inhibitor in combination with progesterone as a means of preserving fertility in patients with early-stage mismatch repair-deficient (MMRd) endometrial cancer who wish to preserve fertility.

This study is a prospective, multi-center, randomized controlled phase II trial to compare the efficacy of perioperative SOX plus toripalimab, toripalimab monotherapy with SOX regimen in participants with dMMR locally advanced gastric or esophagogastric junction adenocarcinoma
