Kalytera Announces Notice of Allowance of US Patent for Treatment of Graft Versus Host Disease

Kalytera Therapeutics,Inc.
Posted on: 15 Nov 17

Kalytera Therapeutics, Inc. (TSX VENTURE: KALY and OTCQB: KALTF) (the "Company" or "Kalytera") is pleased to announce that the United States Patent and Trademark Office has issued a Notice of Allowance for US Patent Application 15/143,694 covering the use of cannabidiol ("CBD") in the treatment of graft versus host disease ("GVHD"). Securing a patent for this proprietary technology represents an important step forward for the Company in its work focused on the treatment of this serious and life-threatening disease.

"We are delighted to receive this Notice of Allowance from the USPTO", said Robert Farrell, J.D., Kalytera's Chief Executive Officer. "There are currently few options to treat persons with GVHD, a critically underserved market. The results of the previous four clinical studies that evaluated CBD in the prevention and treatment of GVHD were exceptional and unprecedented. Based on that data, we believe that our proprietary CBD based therapeutic may provide a major advance in the prevention and treatment of this disease, and we anticipate that we will also soon receive Notice of Allowance for our US Patent Application 14/787,515 that covers both the use of CBD in the prevention of graft versus host disease, and the treatment of graft versus host disease.” Kalytera has exclusive world-wide rights to the technology that is covered by both of these patents.

GVHD is a multisystem disorder that is a common, life-threatening complication of hematopoietic stem cell transplant procedures. GVHD occurs when the transplanted donor cells attack the patient's organs, including the skin, gastrointestinal tract, liver, lungs and eyes. GVHD is associated with acute and chronic illness, infections, disability, reduced quality of life and death.

Kalytera is currently advancing its Phase 2 clinical program evaluating the use of CBD in the prevention of GVHD. Completion of this Phase 2 program will take approximately eight months, and is required by the FDA prior to the initiation of a pivotal Phase 3 study. The Phase 2 program includes an open label, multicenter trial to evaluate the pharmacokinetic and safety profiles of multiple doses of CBD for the prevention of GVHD following allogeneic hematopoietic cell transplantation ("HCT"). The Phase 2 clinical study will take place at the Rabin Medical Center, Beilinson, and Rambam Health Care Campus, Haifa, in Israel. The Company anticipates that, following completion of the Phase 2 study, it will initiate the Phase 3 study as quickly as possible.

CBD is a non-psychoactive cannabis compound that possesses remarkable therapeutic potential across a broad range of diseases and disorders. Kalytera's work in GVHD is expected to be the first of several programs the Company will undertake that will seek to investigate and commercialize this important compound.

About Kalytera Therapeutics

Kalytera Therapeutics, Inc. ("Kalytera") is pioneering the development of a next generation of cannabinoid therapeutics. Through its proven leadership, drug development expertise, and intellectual property portfolio, Kalytera seeks to establish a leading position in the development of novel cannabinoid medicines for a range of important unmet medical needs, with an initial focus on graft versus host disease (“GVHD”) .

Kalytera also intends to develop a new class of proprietary cannabidiol ("CBD") therapeutics. CBD is a remarkable compound that has shown activity against a number of pharmacological targets. However, there are limitations associated with natural CBD, including its poor oral bioavailability. Kalytera will seek to develop innovative CBD formulations and prodrugs in an effort to overcome these limitations, and to target specific disease sites within the body. Kalytera intends to file composition of matter and method of use patents covering its novel inventions, with the goal of limiting future competition.
