Pinnacle Clinical Research

Pinnacle Clinical Research is a private U.S. clinical research site network focused on executing Phase 1-4 drug and device trials across complex therapeutic areas. The company is particularly differentiated in liver disease, CNS, obesity, and cardiometabolic research, with recognized strength in MASLD/MASH trials, noninvasive diagnostics, and diverse patient recruitment. Pinnacle operates a network of fully owned and affiliated research sites with centralized SOPs, quality systems, regulatory support, and shared data infrastructure. Its business model is service-based rather than product-based: it partners with pharmaceutical sponsors and CROs to run clinical studies rather than developing proprietary therapeutics. The organization has expanded through acquisitions and partnerships, including network additions such as Bellaire Clinical Research, Jubilee Clinical Research, Kerwin Medical Center, and participation in the Houston Research Institute transaction.
