SUBCUTANEOUSLY ADMINISTERED ANTI-IL-6 RECEPTOR ANTIBODY.

摘要

The present application discloses methods for treating an IL-6-mediated disorder such as rheumatoid arthritis (RA), juvenile idiopathic arthritis (JIA), systemic JIA (sJIA), polyarticular course JIA (pcJIA), systemic sclerosis, or giant cell arteritis (GCA), with subcutaneously administered antibody that binds interleukin-6 receptor (anti-IL-6R antibody). In particular, it relates to identification of a fixed dose of anti-IL-6R antibody, e.g. tocilizumab, which is safe and effective for subcutaneous administration in patients with IL-6-mediated disorders. In addition, formulations and devices useful for subcutaneous administration of an anti-IL-6R antibody are disclosed.

A surgical instrument includes a handpiece having a user input feature and a user feedback feature. A shaft assembly extends distally from the handpiece. An end effector is disposed at a distal end of the shaft assembly. The end effector includes an active feature responsive to actuation of the user input feature. The active feature is operable to operate on tissue in response to actuation of the user input feature. The user feedback feature is operable to provide feedback to the user that indicates information relating to operation of the end effector. The feedback may include haptic, visual, and/or auditory feedback.
