Kyowa Kirin and GENESIS Pharma announce new partnership for rare disease medicines portfolio in Greece, Cyprus and Malta

December 20, 2022 – Kyowa Kirin Co., Ltd. (TSE: 4151, Kyowa Kirin), a Japan-based global specialty pharmaceutical company, and GENESIS Pharma, a leading regional biopharma company operating in the broader region of Southeast Europe, have announced a commercialization agreement for two new orphan-designated medicines in Greece, Cyprus and Malta. Under the terms of the agreement, GENESIS Pharma will commercialize Burosumab for the treatment of X-Linked Hypophosphataemia (XLH) and Tumour-Induced Osteomalacia (TIO) and Mogamulizumab for two subtypes of cutaneous T-cell lymphoma (CTCL), a rare non-Hodgkin lymphoma, upon local market approval.

“At Kyowa Kirin our purpose is to make people smile”, said Abdul Mullick, President of Kyowa Kirin International. “And through partnering with GENESIS Pharma I am really pleased that we are living that very purpose, leveraging both organisations’ expertise and infrastructure to ensure people impacted by these rare conditions across Greece, Cyprus and Malta will have access to the medicines they need.”

Mr. Constantinos Evripides, Managing Director of GENESIS Pharma stated: “Innovation can offer a profound therapeutic benefit to people living with chronic and rare diseases. With a clear vision to support these patients, we always aim to expand our strong network of international partners that invest in promising R&D in challenging therapeutic areas. Kyowa Kirin is a company with a long heritage and commitment to cutting-edge science and we are very happy and proud to work together in order to help patients that live with these rare diseases in the countries that we operate”.

About X-Linked Hypophosphataemia (XLH)

X-Linked Hypophosphataemia (XLH) is a rare metabolic bone disease that impacts children and adults. It is a life-long and progressive disease that typically presents in early childhood, causing lower limb deformities, stunted growth, and bone and joint pain.1 Symptoms such as dental abscesses, osteoarthritis, enthesopathy (issues with the tendons), and hearing loss may also develop during adulthood.2,3,4 As a result of the disease, some adults may require special equipment to improve their mobility.5,6 The physical limitations as well as pain and stiffness caused by XLH can affect people’s ability to work and socialize, their emotional wellbeing, and their capacity for self-care.

People with XLH have a genetic defect on the X-chromosome, which causes an excessive loss of phosphate through the urine and poor absorption from the gut, resulting in chronically low levels of phosphate in the blood.1,7 Phosphate is a key mineral needed for maintaining the body’s energy levels, muscle function, and the formation of healthy bones and teeth.8,9 XLH is the most common form of hereditary rickets.10 It can sometimes appear in individuals with no family history of the disease but is usually passed down from a parent who carries the defective gene.11

About Tumour-Induced Osteomalacia (TIO)

Tumour-induced osteomalacia (TIO), also known as oncogenic osteomalacia, is an acquired disorder caused by typically small, slow-growing, benign PMTs (phosphaturic mesenchymal tumors).1,2 With fewer than 1,000 cases reported in the medical literature,2 TIO mainly affects adults with a mean onset age of 40 – 45 years.1,3 It is associated with progressive and debilitating musculoskeletal deficits,4,5 ultimately having a detrimental impact on ability to perform daily activities, as well as on physical and social wellbeing.6

TIO is characterised by chronic hypophosphataemia caused by tumour(s) secreting excess fibroblast growth factor 23 (FGF23),1 which can lead to issues such as decreased intestinal absorption of phosphate and compromised vitamin D activation.1,2

The most common signs and symptoms include bone pain, walking difficulty, pathological fractures, height loss and muscle weakness.4 In TIO, muscle weakness and pain severely interfere with physical functioning, including standing up without assistance, walking and ability to work.6 The pain in TIO also severely interferes with mood and moderately interferes with enjoyment of life for those living with it.6

TIO diagnosis is often missed and/or delayed and testing serum phosphate levels is important for diagnosis.1

About cutaneous T-cell lymphoma (CTCL): Mycosis fungoides (MF) and Sézary syndrome (SS)

Mycosis fungoides (MF) and Sézary syndrome (SS) are two subtypes of cutaneous T-cell lymphoma (CTCL), a rare type of non-Hodgkin’s lymphoma that can affect the skin, blood, lymph nodes and internal organs.1 CTCL is associated with disfiguring skin lesions, intractable itching, sleep disturbance and psychosocial problems and has a serious negative effect on quality of life.2

The annual incidence of CTCL in Europe is around 5.2 new cases per 100,000 population3 and it affects around 240 people per million in the region at any one time.4 MF accounts for approximately 60% of all CTCLs,5 is typically indolent and is characterized by skin symptoms including patches or plaques, skin redness and tumours.6 SS is much rarer, accounting for around 5% of CTCLs,7 and is more aggressive8 with high levels of blood involvement by definition.5 It causes very severe itching, total body redness (erythroderma), intense scaling of the skin and frequent hair loss.9

It can typically take between three and six years from CTCL disease onset for a patient to be diagnosed, in some cases it can take decades.5,6 This is sometimes due to the fact that CTCL presents very similarly to other benign skin conditions (e.g. eczema and psoriasis)9; this can mean many patients experience a long, frustrating journey before diagnosis.
