GlaxoSmithKline (GSK) announced that the company has received a Complete Response letter from the US Food and Drug Administration (FDA) for the supplemental New Drug Application (sNDA) for Avodart (dutasteride) for reducing the risk of prostate cancer in men at increased risk for the disease, defined as those who have had a prior negative biopsy due to clinical concern and have an elevated serum prostate-specific antigen (PSA).

A Complete Response letter is issued by the FDA’s Center for Drug Evaluation and Research when the review of a file is completed and it cannot be approved in its present form.

This notification refers solely to the supplemental file specific to a prostate cancer risk reduction indication and not the existing FDA-approved uses.  Avodart is approved for the treatment of symptomatic benign prostatic hyperplasia (BPH) in men with an enlarged prostate to improve symptoms, reduce the risk of acute urinary retention (AUR), and reduce the risk of the need for BPH-related surgery  In combination with the alpha-blocker tamsulosin, Avodart is also approved for the treatment of symptomatic BPH in men with an enlarged prostate.

GlaxoSmithKline – one of the world’s leading research-based pharmaceutical and healthcare companies – is committed to improving the quality of human life by enabling people to do more, feel better and live longer.
