Frequently asked questions about GSI 136

What is GSI 136 used for?

GSI 136 is an investigational small molecule being studied for Alzheimer disease. It has been evaluated in Phase 1 clinical trials involving healthy volunteers, including young and elderly subjects, rather than in patients with confirmed Alzheimer disease. It is not an approved treatment.

Who makes GSI 136?

GSI 136 is developed by Pfizer, Inc., which trades on the New York Stock Exchange under the ticker PFE. Pfizer sponsored both Phase 1 trials of the compound, one conducted in Japan and one in the United States.

What phase is GSI 136 in?

GSI 136 is in Phase 1 development. Two Phase 1 trials have been completed, and no active trials are currently listed. The studies together enrolled 152 participants and were randomized, double-blind, and placebo-controlled.

What clinical trials is GSI 136 in?

GSI 136 has been studied in two completed Phase 1 trials: NCT00719394, which evaluated safety in young and elderly Japanese males and enrolled 72 participants, and NCT00718731, which studied healthy young and elderly subjects in the United States and enrolled 80 participants.

Is GSI 136 the same as GSI-136?

Yes, GSI 136 and GSI-136 refer to the same investigational compound. The hyphenated form appears in the title of the Phase 1 trial NCT00718731, while the unhyphenated form is used elsewhere. Both names describe the same small molecule developed by Pfizer for Alzheimer disease.
