Cytheris to present interim data from ECLIPSE II Hepatitis C multicenter study at AASLD annual meeting

Cytheris SA, a clinical stage biopharmaceutical company focused on research and development of new therapies for immune modulation, today announced that data from an interim analysis of its ECLIPSE II Hepatitis C Phase I/IIa multicenter study will be presented during a late breaker session at The Liver Meeting(R), the 62nd annual meeting of the American Association for the Study of Liver Diseases (AASLD) in San Francisco, November 4-8, 2011.

The ongoing study is evaluating treatment using the company’s investigative immune-modulator, recombinant human Interleukin-7 (CYT107), added to peginterferon and ribavirin (SOC), for four weeks, in genotype one and four treatment experienced patients defined as nonresponders to SOC.

The presentation details are as follows:

Session: Poster session III, Monday, November 7
Session title: HCV: clinical trials and therapeutic developments
Session type: Late breaking poster session
Location: Poster Hall
Abstract number: LB-9
Presentation time: 8:00 AM – 5:30 PM (presenters in attendance: 12:30 – 2:00 PM)
Presentation title: Four weeks of IL-7 (CYT107) added to peginterferon and ribavirin (SOC) is safe, induces a broad immune response associated with HCV

viral  clearance in genotype one and four patients nonresponders to Peg-IFN and RBV.

About recombinant human interleukin-7 (CYT107)

Recombinant human interleukin-7 (CYT107) is a critical immune-modulator for immune T-cell recovery and enhancement. As a growth factor and cytokine physiologically produced by marrow or thymic stromal cells and other epithelia, IL-7 has a critical and, at some steps, a non-redundant stimulating effect on T lymphocyte development, notably on thymopoiesis and, downstream from the thymus, on homeostatic expansion of peripheral T-cells.

Clinical trials including more than 220 patients in Europe, North America, South Africa and Taiwan have demonstrated the potential of IL-7 to expand and protect CD4 and CD8 T-cells. Currently, Cytheris is conducting multiple international investigations of IL-7 in HIV, HCV, HBV, post-BMT and cancer. Additional studies include a NIAID/NIH-sponsored trial (ICICLE) in idiopathic CD4 lymphocytopenia (ICL); a cancer vaccine study in children with Ewing’s sarcoma family of tumors or similar genetic tumors sponsored by US National Cancer Institute; a collaborative study in metastatic breast cancer sponsored by the Centre Léon Bérard of Lyon; and, a multi-company/institutional study (EraMune 01) sponsored by ORVACS (the international HIV organization funded by the French Bettencourt Schueller Foundation) aimed at attacking the HIV viral reservoir.
