05/06-2006 Active Biotech's ANYARA cancer project presented at ASCO in Atlanta

Active Biotech (Stockholm: ACTI.ST) has presented clinical results for its ANYARA project at the major ASCO annual conference (42nd American Society for Clinical Oncology Annual Meeting, June 2 - 6 2006, www.asco.org). At the conference, Active Biotech presented interim data from the ongoing Phase I study of ANYARA for the treatment of advanced non-small cell lung, renal cell and pancreatic cancer.

The results obtained fulfill several of the objectives set up for ANYARA development. It has been possible to determine a reproducible induction of the immunostimulatory cytokine Interleukin-2 (IL-2), as a surrogate marker for T lymphocyte activation, in connection with ANYARA injections. Notably, a correlation between IL-2 induction and prolonged survival for renal cancer patients has previously been showed with the first generation of ANYARA. Furthermore, a selective increase of ANYARA-specific T lymphocytes following treatment was observed, which shows that treatment does not only activate the patients' T lymphocytes in general, but also selectively increase the amount of ANYARA reactive T lymphocytes.

This ANYARA study is being performed at the Fox Chase Cancer Center in Philadelphia, in the US, at the Radium Hospital in Oslo, Norway, and at the Christie Hospital, in Manchester, in the UK.

An additional Phase I study within the ANYARA program is currently in progress. It is a combination study of ANYARA and the established chemotherapy drug Taxotere®. The combination study is being conducted in clinics in the US, Denmark and Russia. A Phase II clinical study with renal cancer patients is scheduled to commence before the end of the year.
