Active clinical trials for "Metaplasia"

The goal of this clinical research study is to learn if dasatinib can help to control myeloproliferative disorders. The safety and tolerability of dasatinib will also be studied.

Phase II trial to study the effectiveness of tipifarnib in treating patients who have myelofibrosis with myeloid metaplasia. Tipifarnib may stop the growth of tumor cells by blocking the enzymes necessary for tumor cell growth.

In this trial, the question is addressed if zoledronic acid (Zometa, Novartis Pharma)could be of clinical benefit for patients with myelofibrosis and myeloid metaplasia (MMM).

Use radiofrequency ablation (RFA) for Gastric intestinal metaplasia (GIM) treatment.

The goal of the study is to understand whether blood levels of hormones produced or metabolized in the stomach reflect the health of the stomach lining. Specifically the study will determine whether the concentration of ghrelin, gastrin, pepsinogens and vitamin B12 reflect the condition of the stomach lining. Hormone concentrations for people with normal/mild gastritis will be compared to people with long-term inflammation of the stomach (chronic atrophic gastritis), and people with pre-cancerous cellular changes (intestinal metaplasia).

The purpose of this study is to determine the maximum tolerated dose (MTD) of TAK-901 in subjects with advanced hematological malignancies, and to further assess the safety and tolerability of TAK-901 at or below the MTD in an expanded cohort of subjects in order to select a dose for future studies.

This study was conducted in 2 serial phases (dosimetry phase and effectiveness phase) to evaluate a balloon-based ablation device (HALO360) that delivers a pre-set amount of energy density (J/cm2) to barrett's tissue. The dosimetry phase evaluated the dose-response and the safety of delivering 6 to 12 J/cm2. The effectiveness phase used 10 J/cm2 delivered twice for all patients, followed by Esophagogastroduodenoscopy (EGD) with biopsies at 1, 3, 6, and 12 months. A second ablation procedure was performed if Barretts esophagus (BE) was present at 1 or 3 months. A complete response (CR) was defined as all biopsy specimens negative for Barrett's Esophagus at 12 months. The effectiveness phase of the present study was extended to a 2.5-year follow-up. This trial incorporated an opportunity for persistent BE to be treated with a focal ablation device (HALO90), achieving a CR in 98.4% of patients by the 2.5-year follow-up,the results of which were published . There is ample evidence that RadioFrequency Ablation (RFA) for Barrett's esophagus is effective and safe. Having additional follow-up (5 years) would add valuable information to the literature, thus aiding the physician in making patient management decisions about the appropriate follow-up interval after RFA.

RATIONALE: Giving thalidomide together with prednisone and cyclophosphamide may lessen symptoms caused by myelofibrosis and myeloid metaplasia. PURPOSE: This phase II trial is studying the side effects and how well giving thalidomide together with prednisone and cyclophosphamide works in treating patients with myelofibrosis and myeloid metaplasia.

The goal of this clinical research study is to find the highest safe dose of RAD001 that can be given as a treatment for leukemia, mantle cell lymphoma, or myelofibrosis. Another goal is to learn how effective the dose that is found is as a treatment.

The purpose of this study is to develop and validate a clinical decision support system based on automated algorithms. This system can use natural language processing to extract data from patients' endoscopic reports and pathological reports, identify patients' disease types and grades, and generate guidelines based follow-up or treatment recommendations
