What was measured

TTR was defined as the time from date of randomization to date of first documented CR or PR for responders, as assessed by the Investigator per RECIST v1.1. CR: disappearance of all target and non-target lesions (TLs) and all pathological lymph nodes (LNs) (target and non target), with short axis \<10mm. PR: ≥30% decrease in sum of diameters (SOD) from Baseline. Only responders were analyzed for this outcome measure.

Analysis population: Participants with CR or PR per investigator assessment by the data cutoff date (31 January 2019) were analyzed for tumor response.

Groups in this outcome

AG-120

Participants received AG-120 500 mg, tablet, orally, QD in each 28-day treatment cycle, until occurrence of disease progression, unacceptable toxicity, confirmed pregnancy, death, subject withdrawal, lost to follow-up, or the sponsor ended the study for up to approximately 45 months.

Placebo

Participants received AG-120 matched placebo, orally, QD in each 28-day treatment cycle, until occurrence of disease progression, unacceptable toxicity, confirmed pregnancy, death, subject withdrawal, lost to follow-up or the sponsor ended the study for up to approximately 7 months. Participants who experienced disease progression and received placebo were allowed to cross over and receive AG-120.
