All of us here at DHAT take great pride in providing the most up to date medical and surgical gastroenterology care based on the principles of best practices and evidence based delivery. In 2016, we were pleased to announce the birth of the DHAT Research Institute (DRI). Through this new Clinical Research Institution, located in Richardson, Texas, we are now offering patients access to future treatments in gastroenterology care.
In order for new treatments and therapies to receive FDA approval, they must pass through four different phases. Phase 1, Phase 2 and Phase 3, are pre-FDA approval, while Phase 4 is considered post-FDA approval. DHAT Research Institute will be participating in all four Phases, 1 through 4, but its primary focus will include clinical trials that are in Phase 2 and Phase 3 clinical trials.
DHAT Research Institute will be participating in multiple clinical trials giving patients access to new treatments before they are FDA approved and available to the general public. We are currently looking to offer opportunities for patients with Crohn’s Disease, Ulcerative Colitis, Gastroparesis, Fatty Liver Disease, Hepatitis B and C, gastrointestinal infections including Clostridium Difficile, H. Pylori, and Eosinophilic Esophagitis. DHAT Research Institute is excited to bring the future of gastroenterology medicine to adults and pediatrics in the Dallas-Fort Worth area. For more information regarding clinical trials, please reach out to one of our Clinical Research Coordinators at (972) 265-8201 or email us at email@example.com.
