6.1 Clinical Studies Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

In addition, the clinical trials were not designed to establish comparative differences across study arms with regards to the adverse reactions discussed below.

Kidney transplant patients were treated with tacrolimus extended-release capsules (N=214) or tacrolimus immediate-release product (N=212) and concomitant immunosuppressants (median duration of exposure of 12 months) in a randomized, open-label, active-controlled trial of mostly U.S.

patients (Study 1) [see Clinical Studies ( 14.1 )] .

The types of adverse reactions seen in Study 1 were similar to the adverse reactions seen in Study 2 [non-U.S.

trial in kidney transplant patients treated with tacrolimus extended-release capsules (N=331) or tacrolimus immediate-release product (N=336) and concomitant immunosuppressants] [see Clinical Studies ( 14.2 )] .

In Study 1, the proportion of patients who discontinued treatment due to adverse reactions was 9% and 11% in the tacrolimus extended-release capsules and tacrolimus immediate-release treatment groups, respectively, through 12 months of treatment.
