Decentralized Dietary UC Pilot Trial
2015年11月5日 更新者：Transparency Life Sciences
A Pilot Study Investigating a Decentralized Approach to Studying Dietary Intervention in Patients With Ulcerative Colitis
This study is designed to assess differences in remote and on-site patient study participation in the State of Massachusetts, as well as the significance of dietary interventions and their impact on UC.
The study will activate one site with a Principal Investigator who will utilize each subject's local care system (local Gastroenterologist) to collect study data, along with telemonitoring and video visits, to make key study assessments and decisions regarding subjects' progression in the study.

|---|---|
|
有源比较器：Traditional
Subjects in Study Arm 1 will undergo a screening process, and if randomized, will follow a traditional, site-based clinical trial model and undergo a baseline visit and 3 more in-person visits with the Principal Investigator (total of 4 visits). Subjects in each Study Arm will be randomized (2:1) to follow one of two dietary regimens during the study: the Combined Anti-Inflammatory Diet (CAID) or Control (standard nutritional advice). |
The CAID requires participants to modify their diet to include certain types of foods that may have anti-inflammatory properties.
Participants on the CAID will be required to abstain from red meat and alcoholic beverages.
|
|
有源比较器：Remote
Subjects in Study Arm 2 will undergo a screening process, and if randomized, will undergo one Baseline visit at the local Gastroenterologist's office and 4 video visits with the Principal Investigator. A mobile nurse will visit subjects at a distant location (such as their home) to obtain blood samples at visits 1 and 4. Subjects in each Study Arm will be randomized (2:1) to follow one of two dietary regimens during the study: the Combined Anti-Inflammatory Diet (CAID) or Control (standard nutritional advice). |
The CAID requires participants to modify their diet to include certain types of foods that may have anti-inflammatory properties.
Participants on the CAID will be required to abstain from red meat and alcoholic beverages.
