The invention relates to the use of a JAK1 kinase-selective inhibitor that has minimal inhibitory activity towards Jak2 kinase for treating a disease, such as an inflammatory disease (e.g., moderate to severe Rheumatoid Arthritis) and/or bone loss, either alone or in combination with a DMARD (disease modifying anti-rheumatic drug), such as methotrexate. The invention also provides pharmaceutical composition, dosage formulation, administration route, and dosage schedule thereof.
该发明涉及使用一种对JAK1激酶具有选择性抑制作用且对Jak2激酶的抑制活性最小的
抑制剂来治疗疾病,例如炎症性疾病(例如中重度类风湿关节炎)和/或骨质流失,可以单独使用或与
DMARD(疾病修饰性抗风湿药物)如
甲氨蝶呤联合使用。该发明还提供了药物组合、剂量配方、给药途径和剂量方案。
