TRPharm and Kastle Therapeutics Announce an Exclusive Distribution Agreement for KYNAMRO® in Turkey and the Middle East

Istanbul, Turkey, December 25, 2017 – TRPharm and Kastle Therapeutics, LLC today announced that the companies have entered into an agreement granting TRPharm exclusive rights in Turkey and Middle East to commercialize KYNAMRO® (mipomersen sodium) injection.

Under the agreement, TRPharm will be responsible for marketing authorizations, market access, commercialization, and distribution throughout Turkey, Lebanon, Saudi Arabia, Kuwait, the United Arab Emirates, Qatar, Bahrain, and Oman. KYNAMRO was approved by the FDA in January 2013.

“We are pleased to enter into this collaboration with Kastle Therapeutics, where we have the chance to bring our unique strengths together to improve the health of HoFH patients across the region.  This partnership also supports our long-term commitment to rare diseases. Despite the recent advances in the field of LDL-cholesterol lowering, there are still a significant number of patients with this unique mutation that have an unmet medical need,” said Mehmet C. Göker, Chief Executive Officer of TRPharm. “We look forward to rapidly establishing the regional footprint of KYNAMRO and bringing value to patients through a strong dialogue with physicians and authorities while investing into science and awareness around this critical condition.”

About KYNAMRO® (mipomersen sodium) injection

KYNAMRO is an oligonucleotide inhibitor of apolipoprotein B-100 synthesis. KYNAMRO is indicated as an adjunct to lipid-lowering medications and diet to reduce low density lipoprotein-cholesterol (LDL-C), apolipoprotein B (apo B), total cholesterol (TC), and non-high density lipoprotein-cholesterol (non HDL-C) in patients with homozygous familial hypercholesterolemia (HoFH). KYNAMRO reduces LDL-C by preventing the formation of atherogenic lipoproteins, the particles that carry cholesterol through the bloodstream.  KYNAMRO acts by blocking the production of apo B, the protein that provides the structural core for these atherogenic particles, including LDL.

About Homozygous Familial Hypercholesterolemia (HoFH)

HoFH is a rare genetic disease characterized by extreme cholesterol levels. People with HoFH have inherited mutations that limit the body’s ability to clear cholesterol.  HoFH is extremely rare. The true prevalence of HoFH may be underestimated because of inadequate data and under-diagnosis.  Medical literature includes different criteria for making an HoFH diagnosis. HoFH may be diagnosed by clinical or genetic parameters, and may be considered in cases of unusually high LDL-C. Because HoFH is genetic, it is important that all family members of people with HoFH know their cholesterol levels, regardless of their age.
