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

Phase 2

Active, not recruiting

• Conditions: Growth Hormone Deficiency
• Interventions: Drug: LUM-201

• Registration Number: NCT05250063
• Lead Sponsor: Lumos Pharma

Brief Summary

This is a multi-national trial. The goals of the trial are to study the growth response to LUM-201 administration in children with idiopathic growth hormone deficiency (GHD) previously treated with daily rhGH for 12 months in the LUM-201-01 trial.

Detailed Description

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.
