Discovery and Clinical Development of Dutasteride, a Potent Dual 5α- Reductase Inhibitor

Author(s): Stephen V. Frye.

Abstract:

In this review the preclinical medicinal chemistry, biochemistry and clinical results achieved in the treatment of prostatic disease with dutasteride, a dual inhibitor of type 1 and type 2 5α-reductase are described. During the discovery phase, dutasteride was optimized to inhibit both forms of human 5 α-reductase (5AR) via extensive structure activity relationship studies versus the cloned human isozymes. Dutasteride has subsequently been shown to improve disease measures in patients with symptomatic benign prostatic hyperplasia (BPH) in three randomized, placebo-controlled, Phase III clinical studies lasting for 2 years. Additionally, dutasteride is now under study for the ability to reduce the incidence of prostate cancer in men at high risk of the disease - an indication where the unique dual inhibitor nature, half-life and tolerability of dutasteride may be especially significant factors in determining treatment success. The connections between preclinical drug design and clinical outcomes during the discovery and development of dutasteride are exemplified.
