Caltius Structured Capital, an investment fund based in Brentwood, has invested in a Washington, DC-based health care advisory company for an unknown sum.

Caltius announced Jan. 24 it made a junior capital investment in Musculoskeletal Clinical Regulatory Advisers, an advisory firm and clinical research organization for the neuro-musculoskeletal and medical device industries.

“We are very excited to be partnering with MCRA to help management continue the company’s proven growth strategy,” said Alisa Frederick, managing director for Caltius, in a statement. “MCRA’s holistic approach to solving clients’ critical and complex issues has earned the company a market-leading position in the regulatory and clinical consulting space.”
