Active Biotech Publishes Data Regarding the TASQ Prostate Cancer Project

Active Biotech (ACTI.ST) publishes a new paper* in the next issue of the scientific journal "The Prostate", in collaboration with Dr. John T. Isaacs of The Johns Hopkins University School of Medicine, Baltimore, MD, USA.

The article presents pre-clinical data regarding Active Biotech's project TASQ for the treatment of prostate cancer.

The objective for the TASQ project is to develop a pharmaceutical product that can be administered orally for the chronic treatment of prostate cancer. TASQ is currently in Phase I clinical trials in prostate cancer patients.

Phase II studies are scheduled to commence during 2007.

The tumor growth of a series of human prostate cancer xenografts in male nude mice given nothing vs. TASQ alone, or in combination with androgen ablation or with androgen ablation plus docetaxel (Taxotere®), were evaluated. Daily oral treatment with TASQ consistently inhibited the tumor growth of all of the six xenograft models tested in a dose dependent manner via an anti-angiogenic response. TASQ's anti-prostate cancer efficacy was enhanced when combined with androgen ablation or with androgen ablation plus docetaxel. The results also documented that differences in serum PSA in TASQ treated hosts vs. controls are related to inhibition of tumor growth.

This indicates that in humans, changes in PSA velocity or doubling time may indicate a therapeutic response to TASQ.
