About the Phase 2 Study in C9orf72-related ALS/FTD:
The Phase 2 study in patients with C9orf72-related ALS/FTD was a multi-center, randomized, double-blind, placebo-controlled parallel-group, two-arm study with an open-label treatment period. Participants (n=42) were randomized 3:2 to receive daily doses of 400 mg of TPN-101 or placebo. The study included a six-week screening period, a 24-week double-blind treatment period, a 24-week open-label treatment period, and a follow-up visit four weeks post-treatment. Further information on the study can be accessed at ClinicalTrials.gov.
About TPN-101:
TPN-101 specifically inhibits the LINE-1 reverse transcriptase that promotes LINE-1 replication. LINE-1 elements are a class of retrotransposable elements that in humans are uniquely capable of replicating and moving to new locations within the genome. When this process becomes dysregulated, LINE-1 reverse transcriptase drives overproduction of LINE-1 cDNA, triggering innate immune responses that contribute to neurodegenerative, neuroinflammatory, and aging-related disease pathology.
About ALS and FTD:
ALS is a neurodegenerative disease characterized by progressive muscle weakness, and loss of ability to speak, eat, move or breathe. FTD is a progressive frontal/temporal cortex disease associated with behavior and personality changes, emotional problems, and difficulty walking, communicating, or working. A C9orf72 hexanucleotide repeat mutation accounts for 10-15% of both disorders. With onset commonly in middle age or earlier, patients with ALS have a mean survival of two to three years. Patients with FTD have a mean survival of nine years.
