6.1 Clinical Trials 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.

TAVALISSE was studied in two randomized, double-blind, placebo-controlled trials that were identical in design.

The data described below reflect exposure to TAVALISSE in 102 patients with chronic ITP who had received one or more prior ITP treatment(s).

Groups were stratified with respect to splenectomy and severity of thrombocytopenia.

Patients randomized to the TAVALISSE arm received 100 mg orally twice daily.

Based upon platelet count and tolerability, if a patient's platelet count did not increase to at least 50 × 10 9 /L, the TAVALISSE dose could be increased to 150 mg twice daily after one month.

In the placebo controlled studies, the median duration of TAVALISSE exposure in these studies was 86 days (range 8 to 183) [see Clinical Studies (14) for additional details for patients on TAVALISSE ] .
