Viking Therapeutics Initiates Clinical Trial For VK5211, A Selective Androgen Receptor Modulator (SARM), For Acute Hip Fracture
SAN DIEGO, Sept. 1, 2015 (GLOBE NEWSWIRE) -- Viking Therapeutics, Inc. ("Viking") (NASDAQ:VKTX), a clinical-stage biopharmaceutical company focused on the development of novel, first-in-class or best-in-class therapies for metabolic and endocrine disorders, today announced that it has initiated the clinical development program for VK5211, the company's lead program for muscle and bone disorders. VK5211 is an orally available, non-steroidal selective androgen receptor modulator (SARM) being developed for the treatment of patients recovering from non-elective hip fracture surgery.
Investigators have dosed the first subjects in the initial portion of the VK5211 clinical program, which consists of a brief safety, tolerability and pharmacokinetic study in healthy elderly subjects. This will be followed by a randomized, double-blind, parallel group, placebo-controlled Phase 2 study to evaluate the efficacy, safety and tolerability of VK5211 in patients recovering from hip fracture surgery. Approximately 120 patients will be enrolled in the efficacy study with the primary objective of determining the effects of VK5211 on lean body mass after 12 weeks of treatment. Secondary and exploratory objectives include assessments of functional performance, quality-of-life and activities of daily living, as well as safety, tolerability and pharmacokinetic assessments. Viking anticipates that the first patient in the efficacy study will be dosed in the fourth quarter of 2015.
"We believe VK5211 has the potential to meet a significant unmet medical need in the hip fracture setting based on the drug's potent anabolic effect on both lean body mass and bone mineral density. These unique characteristics may benefit patients recovering from surgery, where loss of muscle and bone contribute to the poor recoveries and increased risk of further complications that are often observed," said Brian Lian, Ph.D., chief executive officer of Viking Therapeutics. "In addition to our exciting progress with VK5211, we are also looking forward to key near-term milestones for pipeline programs, including the planned fourth quarter initiation of a Phase 2 trial of our novel thyroid beta agonist VK2809 in patients with hypercholesterolemia and fatty liver disease, as well as the continued advancement of our thyroid agonist program in the orphan disease X-linked adrenoleukodystrophy (X-ALD)."
VK5211 is an orally available, non-steroidal selective androgen receptor modulator (SARM) entering Phase 2 development for the treatment of patients recovering from non-elective hip fracture surgery. VK5211 belongs to a family of novel orally available, non-steroidal SARM compounds based on tissue-specific gene expression and other functional, cell-based technologies. Viking believes that VK5211 has the potential to produce the therapeutic benefits of testosterone with improved safety, tolerability and patient acceptance due to a tissue-selective mechanism of action and an oral route of administration. In Phase 1 clinical trials, VK5211 demonstrated statistically significant increases in lean body mass among treated subjects following 21 days of treatment. In a pre-clinical model of osteoporosis, VK5211 demonstrated improvements in bone mineral density, bone mineral content, bone strength, and other measures.
