 (submitted: May 15, 2020)
Number of Participants With Serious or Non-serious Adverse Events [ Time Frame: Up to 34 months ]
Study-emergent adverse events (including the onset of new adverse events or worsening of pre-existing adverse events) were recorded from the time of first dose in this study to the end of study participation. All laboratory test, vital sign, or electrocardiogram parameter abnormalities deemed clinically significant by the Investigator were to be reported as adverse events.

 (submitted: September 17, 2014)
  • Number of participants with serious and non-serious adverse events [ Time Frame: Up to 29 months ]
  • Change from Baseline in laboratory test values [ Time Frame: Up to 29 months ]
    Standard hematology and serum chemistry parameters to be measured
  • Change from Baseline in vital signs [ Time Frame: Up to 29 months ]

Descriptive Information
Brief Title  ICMJE Open-Label Study of Leuco-methylthioninium Bis(Hydromethanesulfonate) (LMTM) in Subjects With Alzheimer's Disease or Behavioral Variant Frontotemporal Dementia (bvFTD)
Official Title  ICMJE An Open-Label, Extension Study of the Effects of LMTM in Subjects With Alzheimer's Disease or Behavioral Variant Frontotemporal Dementia (bvFTD)
Brief Summary The purpose of this study is to provide subjects who have completed participation in a Phase 2 or Phase 3 trial of LMTM continued access to therapy and to evaluate the long-term safety of LMTM.
Detailed Description Not Provided
Study Type  ICMJE Interventional
Study Phase  ICMJE Phase 3
Study Design  ICMJE Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Condition  ICMJE
  • Alzheimer's Disease
  • Behavioral Variant Frontotemporal Dementia
Intervention  ICMJE Drug: 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. The maximum allowable dose was 300 mg/day (or in those countries where limited by a Competent Authority or Ethics Committee, 200 mg/day).
Study Arms  ICMJE Experimental: LMTM
