In a palatability survey conducted on Day 14 of the open-label phase, of those surveyed (n/N=66/85) 78% liked the taste of XELJANZ Oral Solution*3
3

*Based on a palatability survey that involved 85 patients receiving XELJANZ Oral Solution at 5 mg BID or equivalent weight-based lower dose. At Week 2 of the open-label phase, taste acceptability was assessed by having either the patient, the patient’s parent or guardian, or the study site staff record the patient’s reaction to the oral solution taste. One of 5 categories that most adequately reflected the patient’s response to the taste of the oral solution was selected. Age-appropriate tools (using wording and/or graphic facial expressions) were used to assess taste acceptability. Those surveyed selected from the following categories using a Likert scale: 34 patients liked ‘very much’ (40%), 32 liked ‘a little’ (38%), 6 were ‘not sure’ (7%), 8 disliked ‘a little’ (9%), and 4 disliked ‘very much’ (5%).3
