Filter by:Many patients have cancers that have increased activity of a protein called STAT3 that contributes critically to the development and growth of their cancer. Despite our knowledge of STAT3's importance to cancer, scientists and doctors have not developed a drug that targets it and that patients can take to treat their cancer more effectively than treatments that are now available. Tvardi Therapeutics, Incorporated has developed a compound, TTI-101, which can be given by mouth and acts as a direct inhibitor of STAT3. Administration of TTI-101 to mice demonstrated that it blocked growth of cancers of the breast, head and neck, lung, and liver and it was safe when administered at high doses to mice, rats, and dogs. In this application, Tvardi is proposing to further develop TTI-101 for treatment of solid tumors for which the prognosis is dismal. The investigators will determine how safe it is when administered to patients with cancer, determine whether an adequate dose can be administered to patients with cancer that will block STAT3 in their cancer, and determine whether treatment with TTI-101 leads to reduced growth of their cancer.
Circulating tumour DNA (ctDNA) is a promising tool when monitoring the residual disease in colorectal cancer (CRC). Current staging procedures are insufficient to identify the patient cohort at high risk, who might benefit from additional adjuvant therapy. We will show that the assessment of ctDNA is a non-invasive approach and easily taken at different time points via simple blood draw to monitor residual disease from the colorectal cancer patients after primary surgery. Minimal residual disease could be used in the future for individualized treatment decisions after primary surgery.
Colorectal cancer (CRC) has the third highest cancer incidence in the world. There is mounting evidence that the intestinal microbiota plays an important role in colorectal carcinogenesis. but there is no information on protozoa of intestinal microbiota except Blastocystis hominis, although data on this issue is scarce. In this study we are going to evaluate the prevalence of intestinal helminthes and protozoa in CRC patients and control group that includes random residents. Patients will be examined before, after surgery and chemotherapy. Parasites and protozoan infection intensity will be estimated by triple coproscopy.
This is a multicenter Phase 1b, open-label study to assess safety, tolerability, preliminary efficacy, and pharmacokinetics (PK) of cabozantinib taken in combination with atezolizumab in subjects with multiple tumor types, including advanced urothelial carcinoma (UC) (including bladder, renal pelvis, ureter, urethra), renal cell carcinoma (RCC), castration-resistant prostate cancer (CRPC), non-small-cell lung cancer (NSCLC), triple negative breast cancer (TNBC), ovarian cancer (OC), endometrial cancer (EC), hepatocellular cancer (HCC), gastric cancer/gastroesophageal junction cancer/lower esophageal cancer (GC/GEJC/LEC), colorectal cancer (CRC), head and neck (H&N) cancer, and differentiated thyroid cancer (DTC). The study consists of two stages: in the Dose Escalation Stage, an appropriate recommended cabozantinib dose for the combination with standard dosing regimen of atezolizumab will be established; in the Expansion Stage, tumor-specific cohorts will be enrolled in order to further evaluate the safety and efficacy of the combination treatment in these tumor indications. Three exploratory single-agent cabozantinib (SAC) cohorts may also be enrolled with UC, NSCLC, or CRPC subjects. One exploratory single-agent atezolizumab (SAA) cohort may also be enrolled with CRPC subjects. Subjects enrolled in the SAC cohorts and SAA cohort may receive combination treatment with both cabozantinib and atezolizumab after they experience radiographic progressive disease per the Investigator per RECIST 1.1. Due to the nature of this study design, some tumor cohorts may complete enrollment earlier than others.
Different subtypes of serrated lesions have been recently described. Among them, both sessile serrated polyp/adenoma (SSP/A) and traditional serrated adenoma (TSA) could have malignant potential through the serrated pathway or CIMP. These lesions, as a potential source of interval cancer, should also be considered in colorectal cancer (CRC) population-based screening programs. It is believed that this new described pathway could be responsible for up to 30% of all CRC. Unlike the traditional adenoma, serrated lesions are difficult to diagnose because of their particular endoscopic appearance and their still unclear histological criteria. Furthermore, they have specific molecular changes and, through them, they could evolve into CRC faster than the adenoma. The real prevalence of the serrated lesions and their specific risk for developing new synchronous/metachronous lesions, or even malignancy, remains unknown. For all these reasons, we don't know if these patients could constitute a different CRC-risk group and if specific recommendations are needed during their follow-up. This is a prospective longitudinal study developed within the framework of the CRC-screening program in the Valencian Community (Spain). We expect to include a total of 700 individuals who will be followed during 10 years. In our study, we will collect epidemiologic variables related to the patient, variables related to all the polyps, and mutational (BRAF, KRAS, MSI), and CpG-island methylation status of serrated lesions. Strict endoscopic and histological criteria will be applied for the diagnosis of serrated lesions. All lesions detected at the index colonoscopy and during follow-up will be evaluated. The purpose of this study is to correlate epidemiologic data, histological characteristics and the molecular profile of the serrated lesions with findings during follow-up, in order to define stratified groups according to their risk of developing new lesions or CRC in the future.
This is an observational study to look at the impact of the Enhanced Recovery After Surgery system for colorectal surgery (Group 1) in shortening hospital length of stay, reducing postoperative narcotic consumption, lowering Visual Analog Scale scores, decreasing the incidence of postoperative nausea and vomiting, and reducing 30-day readmission when compared to patients who had colorectal surgery performed at UAMS prior to the implementation of the Enhanced Recovery After Surgery system (Group 2). This is a retrospective study using de-identified records and therefore will not require subject enrollment and is NOT Human Subjects Research.
The purpose of this study is to determine whether inreach and outreach strategies will be superior to usual care, and combination of both will be superior to either strategy alone.
This study has two portions. The main goal of the Phase I portion of this research study is to see what doses of CB-839 and capecitabine can safely be given to patients without having too many side effects. Other purposes of this research study will be to determine what side effects are seen with this combination of medicines. The Phase II portion of the study will test how many patients show shrinkage in their tumor with this combination of medicines and what changes occur inside the cancer cells and blood cells after treatment.
Randomized Single-blind Placebo-controlled Clinical Study of Safety and Tolerability of CBLB502 as a Neo-adjuvant Treatment in Patients With Colorectal Cancer, With Different Doses and Regimens
Treatment with FOLFOXIRI (5-fluorouracil, oxaliplatin, irinotecan) can be effective, but it has serious side effects, which may require hospitalization. The purpose of this study is to investigate whether the addition of tocotrienol can reduce the side effects to FOLFOXIRI otherwise leading to hospitalization.
