Limitations of pooled and long-term extension (LTE) data2
  • Pooled, post hoc analysis of studies from the RA clinical trial program are subject to certain limitations. First, unlike ORAL Surveillance, the patient population is not limited to a high-risk population but includes all enrolled patients. Second, endpoints of interest (such as MACE and malignancy for ORAL Surveillance) were not all specifically defined or adjudicated. Additionally, ORAL Surveillance was a long-term safety study (vs RCT phase 3 which are short term and designed to test efficacy). Resultant incidence rates in ORAL Surveillance differed from rates seen from pooled study data, suggesting the pooled data may be obscuring information about predictors of events given adverse rates may differ from one patient population to another and may change over time
  • ​​​​​​​LTE studies may provide useful data, however, conduct of open-label LTE studies where both treatment and dose are known to both investigator and patient is subject to certain biases and limitations. Most participants were known to have responded to, and tolerated, XELJANZ® (all had completed a qualifying study), hence our findings might not be generalizable to patients new to XELJANZ
  • ​​​​​​​Biases include, but are not limited to, patient selection (patient willingness or ineligibility to enroll, which may be due to a prior serious AE), prior treatment, volunteer, observer, initial dose or study drug, investigator/patient expectation and study duration. Limitations include, but are not limited to, AE frequencies and incidence rates subject to change over time due to patient entry/exit, dose changes influenced by both investigator and patient, dose restrictions in certain countries, the number of patients and exposure for a specific safety event possibly differing depending on the timing of censored events, and the number of observed patients with longer exposure times becoming lower
