Rainier Clinical Research Center 2026 Data Breach Investigated
By Data Breach Law Group | Posted on April 3, 2026 · Washington
Rainier Clinical Research Center in Washington reported a significant data security incident on April 3, 2026, potentially exposing highly sensitive personal and medical information. Our firm is now investigating the breach to determine the full scope and its impact on clinical trial participants.
Rainier Clinical Research Center, a Washington-based organization specializing in clinical trials, reported a data breach incident on April 3, 2026, to the state's Attorney General. The nature of the breach remains unspecified, but it involved unauthorized access to systems containing extensive personal and health data collected during research studies.
The exposed data categories include Full Name, Date of Birth, Social Security Number, Medical Record Number, Clinical Trial Participation History, Health Insurance ID Number, Diagnosis and Treatment Information, and Contact Information. Such a combination of identifiers and detailed health information poses substantial risks to affected individuals.
This sensitive data, particularly clinical trial records and medical diagnoses, cannot be easily changed or replaced, unlike credit card numbers. Its exposure increases the risk of medical identity theft, fraudulent insurance claims, unauthorized access to medical services, and targeted phishing attempts that leverage private health conditions.
As an entity handling Protected Health Information (PHI) and personal identifiers, Rainier Clinical Research Center is subject to stringent regulations like HIPAA and the Washington Health My Data Act. These laws require robust cybersecurity measures to protect patient data. A breach often suggests potential gaps in data security protocols or failures to adequately safeguard sensitive records.
