Pemafibrate, also known as K-877 and (R)-K 13675, is a PPAR alpha agonist. (R)-K-13675 decreases the secretion of inflammatory markers without affecting cell proliferation or tube formation. Peroxisome proliferator-activated receptor-alpha (PPAR-alpha) is a key regulator of lipid and glucose metabolism and has been implicated in inflammation. (R)-K-13675 was associated with the inhibition of inflammatory responses without affecting cell proliferation or angiogenesis, and subsequently may induce an anti-atherosclerotic effect.

Pemafibrate had been filed NDA by Kowa for the treatment of dyslipidemia in the Japan in 2015.

Pemafibrate is in phase II clinical trials for the treatment of dyslipidemia in the US and EU.

Example 5 Synthesis of (R)-2-{3-[N-(benzoxazole-2-yl)-N-(3-(4-methoxyphenoxy)propyl)aminomethyl]phenyloxy}butyric acid (Compound (6))

  • Ethyl (R)-2-{3-[N-(benzoxazole-2-yl)-N-(3-(4-methoxyphenoxy)propyl)aminomethyl]phenyloxy}butylate (26.0 g) was dissolved in ethanol (200 mL), and 1.5N NaOH (50 mL) was added to the solution, followed by stirring for 1 hour at room temperature. The reaction mixture was washed with diethyl ether, and the formed aqueous layer was acidified with 4N HCl under ice cooling. The thus-treated aqueous layer was extracted with ethyl acetate, and the extract was washed sequentially with water and saturated brine. The washed extract was dried over sodium sulfate anhydrate and concentrated under reduced pressure. The residue was purified through silica gel column chromatography (chloroform/methanol=10/1), to thereby yield the target product (21.3 g, 87%, 98% ee).

Landmark Trial Entitled “PROMINENT” To Explore The Prevention Of Heart Disease In Diabetic Patients With High Triglycerides And Low HDL-C

Trial will evaluate if lowering triglycerides and increasing functional HDL with Kowa’s potent selective peroxisome proliferator activator receptor-alpha (PPAR-alpha) modulator, K-877 (pemafibrate) can reduce the elevated risk of cardiovascular disease in high-risk diabetic patients who are already taking statins

Jan 12, 2016, 09:00 ET from Kowa Research Institute, Inc.

RESEARCH TRIANGLE PARK, N.C., Jan. 12, 2016 /PRNewswire/ — Kowa Research Institute, Inc., announced plans to conduct an international, multi-center cardiovascular outcomes trial evaluating triglyceride reduction and increasing functional HDL with K-877 (pemafibrate), in high-risk diabetic patients with high triglyceride and low HDL-C levels who are already taking statins.  K-877 is a highly potent and selective peroxisome proliferator activator receptor-alpha (PPAR-alpha) modulator (SPPARMalpha), a promising category of metabolic therapy.

Paul Ridker, MD, director of the Center for Cardiovascular Disease Prevention (CCVDP) at Brigham and Women’s Hospital (BWH), a teaching affiliate of Harvard Medical School, and Aruna Pradhan, MD, a cardiologist at BWH, will be co-Principal Investigators of the planned trial.

“This trial is unprecedented,” said Gary Gordon, MD, President, Kowa Research Institute, Inc. “Statins are effective in lowering cardiovascular risk among patients with high cholesterol, but residual risk remains, particularly in patients with high triglyceride levels and low HDL-C levels.  Kowa will be the first company to run a major, randomized clinical trial investigating whether modulating PPAR-alpha to lower triglycerides and increase functional HDL in diabetic patients can reduce cardiovascular risk when added to statin therapy.”

Evidence supports a role for triglyceride-rich lipoproteins and low HDL-C as important contributors to atherosclerosis.  Kowa specifically set out to create the most potent and selective PPAR-alpha modulator ever developed, and succeeded with K-877, which is at least 1,000 times as potent and selective as other drugs.  Kowa has completed clinical development of K-877 for hyperlipidemia in Japan, and has submitted it to the PMDA for approval as a new drug.  Kowa’s clinical studies have shown K-877 significantly reduces triglycerides, ApoC3, and remnant cholesterol and increases functional HDL and FGF21.

The Pemafibrate to Reduce cardiovascular OutcoMes by reducing triglycerides IN diabetic patiENTs (PROMINENT) Phase 3 K-877 cardiovascular outcomes trial will recruit an estimated 10,000 high-risk diabetic patients worldwide.  All participants will receive aggressive, standard of care management of cardiovascular risk factors including treatment with high-intensity statins.  In addition, patients will receive either K-877 or placebo.  The trial will include diabetic patients with and without established cardiovascular disease and will test whether K-877 reduces the occurrence of heart attacks, hospitalizations for unstable angina requiring unplanned revascularization, stroke, or death from cardiovascular causes.

“Cardiovascular disease remains the number one cause of death worldwide,” said Dr. Gordon.  “Reducing residual cardiovascular risk with K-877 would be valuable to physicians managing patients’ cardiovascular disease.”
