Reistone Biopharma Ready to Initiate the Global Synchronous Clinical Study on Novel JAK1 Inhibitor


Shanghai, October 22, 2018 / PR Newswire / -- On October 18, Reistone Biopharma Company Limited (“Reistone”) officially announced that, FDA approved its application for the phase II clinical trial of its SHR0302, a novel and small molecule JAK1 inhibitor. Dr. Min Wang Irwin, CEO of the company said that, “Reistone is committed to bringing the innovative drugs developed in China to the world. Approval of this clinical trial is an important starting point and a milestone for Reistone.”

SHR0302 was licensed by the investor of Reistone, Jiangsu Hengrui Pharmaceutical Co., Ltd. (“Hengrui”), and Reistone owns the global rights and interests except for rheumatoid arthritis and topical dermatology. FDA approved this application to conduct the clinical study of ulcerative colitis. The clinical study application of China has been completed at the end of August, while that in Europe is underway.

Ulcerative colitis is an autoimmune disease, and its inflammatory lesions are confined to large intestine mucosa and submucosa, mainly ulcer erosion. The lesions may affect the whole colon. Ulcerative colitis often reoccurs, and its various initial clinical manifestations include bloody diarrhea as the most common one, and abdominal pain, hematochezia, weight loss and emesis, which seriously affect the quality of life of patients. The causes of ulcerative colitis have not been identified, and are generally considered to be related with environment, heredity, infection and immune factors, etc. There are at least two million patients in the world, and the global sales of ulcerative colitis drugs in 2016 was nearly USD 5.0 billion.

At present, biologics include anti-TNF and IL-12/23 in addition to basic therapeutic drugs such as aminosalicylic acid, glucocorticoid and immunomodulator, but there are still unmet clinical needs, including high recurrence rate. Whereas the small molecule drug is convenient for administration, suitable for long-term treatment of patients The existing JAK inhibitors of the first generation are “Pan-JAK inhibitors”. Although inhibitors JAK1 and JAK3 are helpful to improve the anti-inflammatory efficacy, inhibitor JAK2 may also interfere with the signal transduction of erythropoietin and colony stimulating factor, thus causing anemia, neutropenia,lymphopenia and other safety problems. The highly selective JAK1 inhibitor can effectively inhibit the inflammation, and is relatively safe. Perhaps it will become a benchmark for a new generation of JAK inhibitors.
