Recombinant human Interleukin-7 (r-hIL-7) is a critical growth factor for immune T-cell recovery and enhancement. Clinical investigations conducted on more than 75 patients in Europe, the U.S. and Canada have suggested the potential of r-hIL-7 to expand and protect CD4+ and CD8+ T-cells.

"We are delighted that Cytheris has selected us again as their CMO, to manufacture IL-7 in support of their expanded clinical trial program. This is a testimonial to our successful partnership with our clients and our effort to achieve their total satisfaction in our ability to meet their manufacturing needs," said Robert J.
