Sysmex Launches Gene Testing Kit for Blood Cancer (ipsogen JAK2 DX Reagent)

On January 6, 2020 Sysmex Corporation (HQ: Kobe, Japan; Chairman & CEO: Hisashi Ietsugu) reported its launch of the ipsogen JAK2 DX reagent (Press release, Sysmex, JAN 6, 2020, View Source [SID1234552701]). The company received marketing approval on the reagent on December 19, 2018. This product is a gene testing kit that measures the JAK2V617F mutation1 quantitatively, used in the diagnosis of certain hematopoietic tumors generally referred to as blood cancers, specifically polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF).

This product obtained health insurance coverage effective January 1, 2020, becoming Japan’s first diagnostic aid for PV, ET, and PMF to be covered. Going forward, tests using the reagent will be covered under health insurance. This is expected to increase the opportunities for more patients to receive testing.

Representative disorders of Philadelphia chromosome-negative myeloproliferative neoplasms—PV, ET, and PMF—are caused by the oncogenesis of hematopoietic stem cells.2 According to the Japanese Society of Hematology, each year some 5,000–6,000 people in Japan suffer from these disorders.

In the tumor classification guidelines (WHO 2017 classifications) formulated by the International Agency for Research on Cancer, the agency of the World Health Organization (WHO) that specializes in cancer, identification of the causative gene mutation is indicated as a key aspect (major criteria) of the diagnostic standard for PV, ET, and PMF. The JAK2V617F mutation is the major gene mutation seen in most PV, ET, and PMF patients. Hence, the mutation is considered to be of major diagnostic importance to patients with these three disorders.

Doctors diagnose JAK2V617F mutations based on a quantitative value of the JAK2V617F mutation ratio (allele burden).3 An in vitro diagnostic (IVD) medical device for diagnosing the JAK2V617F mutation based on international standards that had received Japanese marketing approval, as well as insurance coverage, was long awaited, as none had previously existed.

In response to these medical needs, on January 1, 2020 Sysmex received health insurance coverage for, and commenced sales of, the ipsogen JAK2 DX reagent, an IVD medical device for measuring the allele burden of the JAK2V617F mutation. Now that this IVD medical device has received marketing approval, as well as insurance coverage, Sysmex believes that more people who are suspected of having PV, ET, or PMF will have opportunities to receive appropriate diagnoses based on international standards.

By working to increase testing opportunities for patients and creating high-value testing and diagnosis technologies, going forward Sysmex aims to continue contributing to the development and advancement of personalized medicine.

Terminology
1 JAK2V617F mutation:
JAK2 refers to the tyrosine kinase JAK2 protein, which transduces the signals for regulating the growth and differentiation of blood cells. JAK2V617F indicates a mutation in which an amino acid (valine) at position 617 of JAK2 protein is replaced by phenylalanine.

2 Oncogenesis of hematopoietic stem cells:
Blood cells (red blood cells, white blood cells, and platelets) are differentiated from hematopoietic stem cells in the bone marrow. Gene mutations in these hematopoietic stem cells leads to oncogenesis, causing a rapid increase of the blood cells.

3 Allele burden:
A quantitative expression of the degree of the JAK2V617F mutation.

Taiho, Astex and MSD Establish Strategic Oncology Collaboration

On January 6, 2020 Taiho Pharmaceutical Co, Ltd., ("Taiho") reported an exclusive worldwide research collaboration and license agreement with Astex Pharmaceuticals (UK), a wholly owned subsidiary of Otsuka Pharmaceutical Co., Ltd. ("Astex"), and a subsidiary of Merck & Co., Inc., Kenilworth, NJ, USA, known as MSD outside the United States and Canada ("MSD") focused on the development of small molecule inhibitors against several drug targets, including the KRAS oncogene, which are currently being investigated for the treatment of cancer (Press release, Taiho, JAN 6, 2020, View Source [SID1234552700]).

"Taiho has used its unique and proprietary drug discovery platform to generate a number of small molecule inhibitors," said Teruhiro Utsugi, Ph.D., managing director at Taiho. "This alliance builds on our KRAS research up to now, and together with MSD it allows us to combine expertise to significantly accelerate the global research, development and commercialization of a number of our mutant KRAS programs by accessing external talent and resources."

Under the terms of the agreement, Taiho, Astex and MSD will combine preclinical candidates and their data with knowledge and expertise from their respective research programs. In exchange for providing MSD an exclusive global license to their small molecule inhibitor candidates, Taiho and Astex will receive an aggregate upfront payment of $50 million and will be eligible to receive approximately $2.5 billion contingent upon the achievement of preclinical, clinical, regulatory and sales milestones for multiple products arising from the agreement, as well as tiered royalties on sales. MSD will fund research and development and will be responsible for commercialization of products globally. Taiho has retained co-commercialization rights in Japan and an option to promote in specific areas of South East Asia.

"At MSD we continue to pursue new regimens designed to extend the benefits of highly selective therapies to more patients with cancer," said Dr. Roger M. Perlmutter, president, MSD Research Laboratories. "This agreement with Taiho and Astex combines our respective small molecule assets and industry-leading expertise in cancer cell signaling to enable development of the most promising drug candidates."

Harren Jhoti, Ph.D., president and CEO of Astex Pharmaceuticals (UK), commented,

"Together with our Taiho colleagues we are delighted to be working with MSD, one of the global leaders in oncology drug development, on this strategic alliance. This collaboration is another testament to Astex’s position as the leader in fragment-based drug discovery."

KRAS is among the most frequently mutated oncogenes in human cancers. It is estimated to occur in approximately 90% of pancreatic cancers1 and 20% of non-small cell lung cancers (NSCLC)2, where they are associated with poorer outcomes.
