Treatment: Drugs: LMTM
The initial LMTM dose was 200 mg/day (one 100-mg tablet twice daily), except in subjects with bvFTD who were taking a reduced dose (i.e., 100 mg/day) upon entering this extension study. The dose could be increased (after at least 13 weeks of treatment) or decreased (at any time at or after 2 weeks of treatment) by the Investigator in 100-mg increments or decrements.
