OPKO Health Enrolls First Patient in Phase 2B Study of OPK88004 to Treat Benign Prostatic Hypertrophy


Posted on: 27 Nov 17

MIAMI, Nov. 27, 2017 (GLOBE NEWSWIRE) -- OPKO Health, Inc. (NASDAQ:OPK) (“OPKO” or “the Company”), announces that the Company has enrolled the first patient in a Phase 2b dose ranging trial of OPK88004, its orally administered selective androgen receptor modulator (SARM), to treat men with benign prostatic hypertrophy (BPH) or enlarged prostate.  BPH is a non-cancerous condition in which an overgrowth of prostate tissue pushes against the urethra and the bladder, limiting the flow of urine.  BPH affects approximately 50 million men in the U.S. 

This trial will enroll approximately 125 men with BPH at 30 sites in the U.S. to identify appropriate doses given over a four month treatment period to reduce prostate size, the primary efficacy endpoint of the study.  The study will also assess secondary endpoints, including blood prostate specific antigen (PSA) levels and body composition parameters such as lean body mass and fat mass. 

Interest in evaluating OPK88004 as a treatment for BPH is based on data from a 12 week study of 350 men who showed significantly decreased fat mass, increased lean body mass, and increased muscle strength without significantly changing PSA levels in the overall population, while reducing PSA levels in men with elevated PSA levels.  The selective and antagonistic properties of OPK88004 appear to be well suited to potentially reduce prostate hypertrophy in BPH subjects, while providing anabolic benefits such as increased lean body mass and muscle strength.  In previously conducted dog studies, treatment with OPK88004 for 6 months decreased prostate weight by up to 75%, demonstrating the potent antagonistic effects of OPK8004 on androgen receptor activity in the prostate.   

“We are enthusiastic to be initiating this study in men suffering from BPH, as there are no adequate treatment options for this common debilitating condition that affects men as they age.  We believe that OPK88004 has the potential of establishing a new standard of care for a disease that affects millions of men worldwide,” stated Phillip Frost, M.D., Chairman and Chief Executive Officer of OPKO Health. 

“Given the large number of patients with BPH, we expect to complete the study and to have topline results before the end of 2018,” added Dr. Frost. 

About Benign Prostatic Hypertrophy
Benign prostatic hypertrophy is a non-cancerous condition in which an overgrowth of prostate tissue pushes against the urethra and the bladder, blocking the flow of urine. Prostate gland enlargement is a common condition in men as they get older. According to the Mayo Clinic, the severity of symptoms in men with BPH varies, but tend to worsen over time. Common signs and symptoms of BPH include frequent or urgent need to urinate, increased frequency of urination at night (nocturia), difficulty starting urination, weak urine stream or a stream that stops and starts, dribbling at the end of urination, straining while urinating, and an inability to completely empty the bladder.

Medications are the most common treatment for BPH and include alpha blockers and 5-alpha reductase inhibitors, both of which have adverse side effects such as sexual dysfunction, dizziness and retrograde ejaculation.  Surgical procedures to treat males with BPH are often associated with complications and lengthy recovery times.
