Phase 2 Study of LUM-201 in Children Who Have Previously Completed the LUM-201-01 Trial (OraGrowtH213)

This trial will have one screening/baseline visit with tests to assess if subjects are eligible to start study therapy. The screening/baseline visit can coincide with the Month 12 visit in the LUM-201-01 trial. Subjects will receive the same dose of LUM-201 as a daily oral dose each morning. LUM-201 will be adjusted for body weight increments at each clinic visit, as applicable. The trial consists of 12 months of treatment. After screening, subjects will return to the clinic for 5 visits. During four of these clinic visits, safety laboratory samples will be collected.
