The presentations include a late-breaking submission that will further highlight the drug candidate's recently announced Phase 2 Week 24 efficacy results. A second abstract will detail TNX-355's activity against CXCR4 and CCR5 tropic viruses. Additionally, results of in vitro combination studies with enfuvirtide will be highlighted.
Phase 2 clinical results showed that TNX-355, when combined with an optimized background regimen, produced a considerably greater reduction in viral load in HIV-infected patients than did placebo in combination with optimized background therapy. The 82-patient clinical trial met its primary endpoint and is continuing to its planned 48-week duration.
About TNX-355
TNX-355 is a humanized monoclonal antibody that binds to CD4 receptors on the surface of CD4-positive cells, preventing the entry of HIV particles into lymphocytes. TNX-355 is the first antibody in development for the treatment of HIV and AIDS. A Phase 2 clinical study demonstrated that TNX-355, plus optimized background therapy, produces a clinical meaningful reduction in viral load against multiple strains of HIV, without depleting CD4-positive cells. TNX-355 was fast tracked by the Food and Drug Administration in 2003. The fast track designation is designed to expedite approval of therapies for life-threatening diseases and allows for rolling new drug application (NDA) submissions.
