Xeljanz Study Does Not Meet Co-Primary Endpoints
Pfizer says its Xeljanz (tofacitinib) failed to meet the co-primary endpoints in the recently completed post-marketing required ORAL Surveillance safety study. The study evaluated Xeljanz safety at two doses versus a TNF inhibitor (TNFi) in subjects with rheumatoid arthritis who were age 50 or older and had at least one additional cardiovascular risk factor.
The co-primary endpoints were the non-inferiority of Xeljanz compared to TNFi in regard to major adverse cardiovascular events and specified malignancies. The pre-specified non-inferiority criteria were not met for primary or secondary comparisons, Pfizer says.
