Period 1 (6-month double-blind): Final tadalafil doses will be assigned after the weight cohort completion from H6D-MC-LVIG (NCT01484431). Tadalafil doses may range from 5 milligram (mg) to 40 mg depending on body weight cohorts. Heavy weight cohort ≥40 kilogram (kg), Middle weight cohort ≥25 kg to <40 kg: administered orally by tablets once a day. Light weight cohort <25 kg: administered orally by suspension once a day.
Period 2 (2-year open-label extension): Participants receiving tadalafil in Period 1 will continue at same dose in Period 2.
Administered orally by tablet form for heavy and middle weight participants. Administered orally by suspension for light weight participants.
Placebo Comparator: Placebo
Period 1 (6-month double-blind): Final placebo dose will be assigned after the weight cohort completion from H6D-MC-LVIG (NCT01484431) to maintain blinding depending on body weight cohort.
Period 2 (2-year open-label extension): Participants receiving placebo in Period 1 will receive tadalafil in Period 2 at the corresponding tadalafil dose in that participant's weight group.
Administered orally by tablet for heavy and middle weight participants. Administered orally by suspension for light weight participants.
