CytoDyn Inc. announced that its ongoing extension study of PRO 140 monotherapy in a cohort of HIV-infected patients has shown complete viral-load suppression for well over a year with some patients approaching 17 months. The company believes that complete virologic suppression through treatment with a single agent, PRO 140, a safe and efficacious antibody, rather than through the widely used HAART combination therapy, could present a significant opportunity to treat HIV patients. Based on these monotherapy results, the Company plans to file a second Phase 3 protocol for PRO 140 monotherapy with the FDA.

CytoDyn is currently conducting a pivotal Phase 3 trial for PRO 140 as an adjunct therapy with expected commercialization in 2017.
