NCT00551512
The purpose of this research study is to find the answers to the following questions: 1. What are the highest doses of CBP501 and cisplatin that can be safely administered as consecutive 2-hours and 1-hour infusions every 21 days? 2. What are the side effects of the combination of CBP501 and cisplatin when given as an infusion every 21 days? 3. What amount of CBP501 and cisplatin are found in the blood at certain times after it is given? 4. Are there any substances in your blood or tumor that can tell us about tumor sensitivity to CBP501 and cisplatin? 5. Will CBP501 given with cisplatin help to treat your cancer?
NCT00489268
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.
