Brief Summary:
This study is looking at how the study drug, tucatinib, affects the heart. Tucatinib is being studied as a possible treatment for breast cancer. This study will recruit healthy volunteers. There are 3 parts in the study. Each volunteer will be in all 3 parts. One part will be to take the study drug, the second part will be to take a placebo (pill with no medicine), and the third part will be to take moxifloxacin. The volunteers will only know what part of the study they are in when they take moxifloxacin. For the study drug and placebo parts, volunteers will take 2 pills by mouth for 5 days. For the moxifloxacin part, volunteers will take 1 pill by mouth for 1 day.
Detailed Description:
This study will evaluate the effects of a steady state therapeutic dose of tucatinib on QTcF (QT interval corrected for heart rate using Fridericia's method) in healthy individuals. In this design, study treatment will be dosed in 3 sequential treatment periods:
Treatment A: Oral doses of 300mg tucatinib for 5 days
Treatment B: Oral doses of matching placebo for tucatinib for 5 days
Treatment C: A single oral dose of 400 mg of moxifloxacin
Patients will be randomized based on 2-Williams-square design to 1 of 6 treatment sequences to maintain the study blind for tucatinib and placebo.
Treatment A: Oral doses of 300mg tucatinib for 5 days
Treatment B: Oral doses of matching placebo for tucatinib for 5 days
Treatment C: A single oral dose of 400 mg of moxifloxacin
Patients will be randomized based on 2-Williams-square design to 1 of 6 treatment sequences to maintain the study blind for tucatinib and placebo.
