The primary objective of this study evaluates the safety and tolerability of multiple, escalating doses of PF-04958242 administered orally to healthy adult participants.This study also evaluates the plasma and urine multiple dose pharmacokinetics (PK) of PF-04958242.
A decision was made to terminate the B1701002 study so that emerging data from the study and from a preclinical study in rats could be further examined and incorporated into a new study design and protocol. This study was previously posted by Pfizer, Inc. Sponsorship of the trial was transferred to Biogen.
