Christopher Peetz has joined the company as Chief Financial Officer.

"Tobira has established an impressive foundation of data for the company's novel dual chemokine inhibitor program in multiple high-value therapeutic areas. With cenicriviroc demonstrating potent antifibrotic effects in preclinical studies, we are poised to commence a proof-of-concept clinical study in liver disease.

"I look forward to leading our team with a clear sense of strategy and purpose through the next stages of clinical development for cenicriviroc in liver fibrosis and as part of a fixed-dose combination treatment for HIV, as well as in executing against our financing and business development objectives."

"Dr. Fischer brings significant depth of leadership experience in the development and commercialization of new medicines addressing HIV and liver disease. His past accomplishments at Jennerex, Ocera, DuPont-Merck and Roche provide him with an ideal background to lead the advancement of cenicriviroc and maximize the development opportunities for this promising therapeutic," said Founder and Director Eckard Weber, MD, Partner, Domain Associates.
