Summary

Participants will take one of 3 different TAK-994 dose for 8 weeks.

Then, half the participants will continue with their dose of TAK-994 and half will take a placebo. In this study, a placebo will look like a TAK-994 tablet but will not have any medicine in it. Participants will take TAK-994 or placebo for 4 weeks.
