Filter by:Prospective observational trial. A full thickness resection of gastric subepithelial tumors is performed after application of full thickness sutures underneath the tumor with the GERDX(TM) device. Hypothesis: This endoscopic method is feasible, effective and safe.
The goal of this clinical research study is to learn how PLX3397 and pembrolizumab work together to affect cancer cells. PLX3397 is designed to target the receptor for CSF1 (CSF1R). Pembrolizumab is designed to block the interaction between the receptor PD-1 and molecules that bind PD-1. In this study, PLX3397 and pembrolizumab are being given together in order to study their combined effects on patients' immune responses to their tumors. Tumor-specific immune responses have been shown to kill cancer cells and/or to stop tumors from growing. Part 1 of the study (dose-escalation phase) will establish the safest dose of PLX3397 to be given in combination with pembrolizumab. Part 2 of the study (expansion phase) will include an evaluation of efficacy of this combination in the following tumor types: - Advanced melanoma: prior anti-PD-1/PD-L1 therapy but never responded - Advanced melanoma: prior anti-PD-1/PD-L1 therapy and responded but later progressed as defined by irRECIST while on therapy - Non-small cell lung cancer - Ovarian cancer - Gastrointestinal Stromal Tumor (GIST) - Squamous cell cancer of the head and neck
This observational study is proposed to evaluate if the trend in the levels of cf-DNA evaluated on a sample of peripheral blood may be related to different clinical behaviors of the disease monitored by radiological investigations conducted.
The purpose of this study is to evaluate the short-term effect of sealant-assisted skin closure in prevention of surgical site infection after laparoscopic surgery.
The goal of this clinical research study is to learn how CGT9486 (fka PLX9486) may affect cancer cells with certain mutations in the KIT gene, specifically in participants with types of advanced solid tumors including gastrointestinal stromal tumor (GIST). CGT9486 (fka PLX9486) is designed to block KIT gene mutations. These mutations can cause cancer and cancer cell growth. By blocking these mutations, the drug may kill the cancer cells with the mutation and/or stop the tumor from growing. By combining CGT9486 (fka PLX9486) with PLX3397 and CGT9486 (fka PLX9486) with sunitinib, the investigators hope to block most KIT gene mutations that drive cancer growth.
An open label randomised trial for adults with histologically confirmed measurable metastatic GIST who have received no other treatment for metastatic disease. The study aims to determine if an alternating regimen of imatinib and regorafenib has sufficient activity and safety in comparison to imatinib alone to warrant further evaluation as a first line treatment for metastatic GIST.
Evaluate the reliability of morphology standards for GIST pathologic type, staging and grading by retrospective analyzing clinical data; on this basis, establish a GIST standardized and individualized treatment mode to maximum benefit GIST patients, avoid under- and over-treatment.
This study evaluates the combination of trametinib and pazopanib in patients with advanced gastrointestinal stromal tumors (GIST).
Famitinib is a tyrosin-inhibitor agent targeting at c-Kit, VEGFR2, PDGFR, VEGFR3, Flt1 and Flt3. Phase I study has shown that the toxicity is manageable. The purpose of this study is to evaluate the efficacy and safety profile of Famitinib in patients with advanced or metastatic gastrointestinal stromal tumor who failed from imatinib therapy.
Gastrointestinal stromal tumors (GISTs) belong to the sarcoma group and are characterized by oncogenic mutations in the c-KIT, PDGFRA, BRAF and NF-1 genes that drive tumor growth. Since tyrosine kinase inhibitors (TKIs) have become available, the median survival of GIST patients increased from 9 months to over 5 years. Consequently, this rare disease has become a role model for other targeted therapies. However, response to TKIs is extremely heterogeneous: ~15% of the patients experience no benefit from imatinib, whereas ~17% of the patients enjoy stable disease for over 9 years. Treatment failure due to primary and secondary resistance is caused in part by mutations in oncogenic genes that cause change in drug sensitivity. A new technique, using circulating tumor DNA, has enabled us to assess mutations in a simple blood sample obtained from patients on treatment, and thus detect new mutations early in the course of the disease. Also, differences in pharmacokinetic drug behavior add to the observed heterogeneity, and may cause resistance due to drug underexposure and thereby proliferation of the least sensitive tumor cells. This offers the opportunity to optimize and personalize targeted treatment for individual GIST patients by timely treatment adaptation based on early detection of secondary TKIs resistance mutations. Achieving this urgently requires data on daily clinical practice, including prospective serial mutation analysis and serial drug plasma concentration measurement. At a fundamental level this will also help to unravel the driving factors behind primary and secondary TKIs resistance in this model disease.
