Advanced Colorectal Cancer

To learn if avutometinib in combination with defactinib and cetuximab can help to control unresectable, anti-EGFR-refractory, advanced colorectal cancer.

This study adopts a randomized, open-label, positive-controlled, multicenter design, aiming to evaluate the efficacy and safety of SHR-A1811 in combination with chemotherapy and bevacizumab versus standard therapy as first-line treatment for advanced colorectal cancer, and to explore the drug's immunogenicity and pharmacokinetic characteristics.

This study will investigate the safety, tolerability, pharmacokinetics, and anti-tumor activity of CBI-1214 in participants with advanced or metastatic Microsatellite Stable (MSS)/Microsatellite Instability Low (MSI-L) Colorectal Cancer

This is a Phase Ib/II clinical study to evaluate the safety, tolerability, pharmacokinetics (PK), and efficacy of MRG007 combination therapy in patients with advanced colorectal cancer.

The ONTOP study is a prospective, single-arm, open-label phase II clinical trial. A total of 32 patients with advanced MSS/pMMR colorectal cancer who have failed first-line treatment will receive second-line standard treatment combined with Ongericimab and toripalimab. Among them, patients who received irinotecan-containing treatment in the first line will be administered the regimen of Ongericimab + toripalimab + bevacizumab + FOLFOX. Patients who received oxaliplatin-containing treatment in the first line will be administered the regimen of Ongericimab + toripalimab + bevacizumab + FOLFIRI. Treatment will continue until disease progression, initiation of new anti-tumor treatment, active request of the subject, or determination by the investigator that study drug administration needs to be terminated. The primary study endpoint is the objective response rate (ORR), and the secondary study endpoints include duration of response (DoR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and safety, etc.

This is a single-center, open-label, single-arm, exploratory phase II clinical trial designed to evaluate the preliminary efficacy and safety of sintilimab in combination with oral gossypol acetate in patients with advanced pMMR/MSS colorectal cancer after failure of at least two prior lines of standard therapy. Eligible participants will have histologically or cytologically confirmed advanced colorectal adenocarcinoma, measurable disease according to RECIST version 1.1, ECOG performance status of 0 or 1, and adequate organ function. Participants will receive oral gossypol acetate once daily, followed by sintilimab administered intravenously every 3 weeks after a gossypol acetate lead-in period. The primary outcome is objective response rate assessed by RECIST version 1.1. Secondary outcomes include disease control rate, progression-free survival, overall survival, duration of response, and safety.

RBS2418 is a specific immune modulator that works through the inhibition of ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1) and is designed to lead to anti-tumor immunity by protecting endogenous 2'-3'-cyclic guanosine monophosphate-adenosine monophosphate (cGAMP) from hydrolysis and leading to the activation of antigen-presenting cells followed by T cell activation. The hypothesis is that RBS2418 versus placebo will be generally safe, well-tolerated, immunogenic, and will lead to anti-tumor responses in adult subjects for the treatment of advanced, metastatic, and progressive colorectal cancer (CRC).

The FOLICOLOR trial aims to evaluate whether a liquid biopsy-guided follow-up strategy can improve outcomes in patients with unresectable, metastatic colorectal cancer (mCRC) receiving first-line systemic treatment. The approach uses NPY methylation-based circulating tumor DNA (ctDNA) analysis from blood samples to monitor treatment response and guide clinical decision-making. Eligible patients are adults diagnosed with unresectable, metastatic colorectal cancer who are starting first-line treatment. The primary goal is to demonstrate a clinically meaningful benefit, particularly in terms of quality of life (QoL) and reduction of treatment-related toxicity, by allowing earlier and more personalized therapeutic adjustments based on liquid biopsy findings.

This is a Phase II trial designed to determine the optimal dose and evaluate the effectiveness of TL938 and trastuzumab in treating patients with HER2+ colorectal cancer that has metastasized or recurred and is inoperable.

Phase II study of simultaneous infusion of levozolinate for injection and 5-FU as first-line treatment for advanced colorectal cancer

This study evaluates the dose safety and efficacy of serine in combination with fluoropyrimidine-based therapies. Primary objective: To determine the safety of oral serine administration. Secondary objectives: 1. To assess the preliminary efficacy of serine in the study population. 2. To establish the recommended Phase 2 dose for oral serine.

This study is an open label, multicenter Phase II clinical trial aimed at evaluating the safety and efficacy of JS207 with or without JS015 in combination with chemotherapy (XELOX) as a first-line treatment for advanced colorectal cancer with MSS/pMMR. The study was divided into two cohorts: Cohort 1 was JS207 combined with XELOX, and Cohort 2 was JS207 combined with JS015 and XELOX.

A study of Cetuximabβ combined with Envolimab and mFOLFOX6 in Subjects with Advanced Colorectal Cancer

This is a multicenter, randomized, open-label, two-stage Phase IIb clinical study to evaluate the efficacy and safety of B1962 in the treatment of advanced colorectal cancer. The subjects were patients with distant metastasis or unresectable locally advanced colorectal cancer who had previously failed oxaliplatin, irinotecan, fluorouracil-based drugs therapy containing disease progression or intolerable toxic side effects. Two dose groups were investigated: Dose group 1: B1962 35 mg/kg, intravenous infusion, Q2W, Dose group 2: B1962 45 mg/kg, intravenous infusion, Q2W.

This study aims to investigate the value of 18F-FDG and 68Ga-FAPI PET/CT in evaluating the outcome of conversion therapy and the prognosis of advanced colorectal cancer (peritoneal metastasis with/without other metastases)

To evaluate the effectiveness and safety of SHR-A1811 combined with apatinib in the treatment of advanced gastric or gastroesophageal junction adenocarcinoma and colorectal cancer.

The aim of this study is to assess the safety and efficacy of human umbilical cord-derived allogenic mesenchymal stem cells (MSCs) engineered to express antitumor chemokine and co-stimulatory molecule. Following systemic administration, these cells are able to migrate into solid tumors such as colorectal tumors. Once enriched in the tumor, they will attract peripheral lymphocytes consisting of T and natural killer (NK) cells, and simultaneously stimulate the infiltrated lymphocytes for persistent and enhanced antitumor immunity. Thus, this MSC-based treatment provides a potentially effective and targeted immunotherapeutic strategy for tumors with unfavorable immune microenvironment and possibly poor response to immune checkpoint blockade (ICB). During this investigator-initiated trial (IIT), colorectal cancer patients will receive modified MSCs every 21 days via intravenous infusion. Increasing does will be tested in the initial cohort and an optimal dose will be chosen for the remaining patients.

To explore the efficacy and safety of Cetuximab in combination with dabrafenib and Tislelizumab in BRAF mutated treatment of advanced colorectal cancer

This study is a single-arm, prospective, open-label observational clinical study to evaluate the efficacy and safety of Bevacizumab combined with Oxaliplatin and TAS-102 in patients with advanced unresectable rectal cancer.
