WHO WAS IN THE CLINICAL TRIALS?
Who participated in the Clinical trials?
The FDA approved MULPLETA based on evidence from three clinical trials of 341 patients with low platelet counts because of chronic liver disease.
Trials 1 and 3 were conducted in Japan and Trial 2 (NCT02389621) was conducted at the sites located in the Europe, Asia, North America, and Australia.

How were the trials designed?
The benefit of MULPLETA was evaluated in two trials (Trials 1 and 2) that enrolled adult patients with low platelet counts who were scheduled to have a procedure that could lead to increased bleeding. Low platelet counts were consequence of chronic liver disease.
All patients were randomly assigned to receive either MULPLETA or placebo tablets once a day for 7 consecutive days. Neither the patients nor the providers knew which treatment has been given until the end of the trials.
The benefit of MULPLETA was assessed based on the percentage of patients from two trials who did not require a platelet transfusion or any other rescue intervention for bleeding up to 7 days following the procedure.
Side effects of MULPLETA were assessed on the data from the same two trials and one additional smaller trial (Trial 3) done earlier.
GLOSSARY
CLINICAL TRIAL: Voluntary research studies conducted in people and designed to answer specific questions about the safety or effectiveness of drugs, vaccines, other therapies, or new ways of using existing treatments.
COMPARATOR: A previously available treatment or placebo used in clinical trials that is compared to the actual drug being tested.
EFFICACY: How well the drug achieves the desired response when it is taken as described in a controlled clinical setting, such as during a clinical trial.
