An adverse event was any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product.
The SVR 12 was defined as hepatitis C virus ribonucleic acid (HCV RNA) less than (\<) lower limit of quantification (LLOQ; 15 international unit per milliliter \[IU/mL\]) detectable or undetectable 12 weeks after actual EOT.
