Troriluzole

Randomization phase (Weeks 1 through 8): Participants received troriluzole 100 mg capsules twice daily (BID) orally for up to 8 weeks in the double-blind (DB) randomization phase.

Extension phase (Weeks 9 through 56): Participants, who completed the randomization phase and for whom the investigator believed open-label (OL) treatment could offer an acceptable risk-benefit profile, entered the extension phase and received OL troriluzole capsules (continuing on the same dose and regimen that was taken at the end of the randomization phase) for up to additional 48 weeks.

* Participants must be able to understand and agree to comply with the prescribed dosage regimens and procedures; report for regularly scheduled office visits; and reliably communicate with study personnel about adverse events and concomitant medications
* Women of childbearing potential must have a negative serum pregnancy test at screening and a negative urine pregnancy test prior to dosing at Baseline

* Participants who report a history of inadequate response (per investigator judgement) to 3 or more adequate trials (including current trial) of any SSRI or SNRI, at an adequate dose and adequate duration (at least 8 weeks) for the treatment of GAD within the 3 years prior to randomization
* Hamilton Depression Rating Scale 17 (HAM-D-17) item 1 of \>1 at Screening or Baseline
* HAM-D-17 of \> 19 at Baseline
