A Multicenter, 24-Month, Randomized, Open-Label, Active Control, Parallel Arm, Phase 2 Study of Daily Oral LUM-201 in Naïve-to-Treatment, Prepubertal Children With Idiopathic Growth Hormone Deficiency (GHD) (OraGrowtH210)

This is a multi-national trial. The goals of the trial are to study LUM-201 as a possible treatment for Pediatric Growth Hormone Deficiency (PGHD) and investigate a predictive enrichment marker (PEM) strategy to select subjects likely to respond to therapy with LUM-201.


This trial will have one screening visit with tests to assess if subjects are eligible to start study therapy. Once subjects have completed screening, and if they are determined to be eligible, they will be randomized to receive one of three oral daily doses of LUM-201 or daily injections of recombinant human growth hormone (rhGH). All subjects will have an equal chance of being placed in any of the four groups.

The trial consists of up to 24 months of treatment. After screening, subjects will return to the clinic for 6 (subjects placed in rhGH group) or 10 visits (subjects placed in LUM-201 group). During several of these clinic visits, subjects will have a physical exam, blood, and urine collections. There will also be 3 phone calls with study staff that will take place between the clinic visits.

Yes No Not Sure

Inclusion Criteria

Have an established diagnosis of idiopathic PGHD as determined by standard diagnostic criteria. Eligible subjects must be naïve-to-treatment and be prepubertal
Morning cortisol ≥ 7 µg/dL or stimulated cortisol ≥ 14 µg/dL
At Screening, be ≥ 3.0 years and ≤ 11.0 years for girls and ≤ 12.0 years for boys
Have HT-SDS ≤ -2.0 or HT-SDS ≥ 2 SD below mean parental HT-SDS
Have a baseline height velocity < 5.5 cm/year based on at least 6 months of growth
Have prepubertal status as evidenced by Tanner Stage I breast development in girls and testicular volume < 4.0 mL in boys
Have a bone age delayed by ≥ 6 months with respect to chronological age
In girls, have genetic testing results to rule out Turner syndrome. If SHOX genetic testing results are available, they need to be negative
Have normal thyroid function. Subjects diagnosed with hypothyroidism must have documented successful treatment for at least 30 days prior to Day 1

Exclusion Criteria

A medical or genetic condition that, in the opinion of the Investigator and/or MM, adds unwarranted risk to use of LUM-201 or rhGH
Any medical or genetic condition which, in the opinion of the Investigator or Medical Monitor (MM), can be an independent cause of short stature and/or limit the response to exogenous growth factor treatment. (Examples: diabetes, idiopathic short stature)
Use of any medication that, in the opinion of the Investigator and/or MM, can independently cause short stature or limit the response to exogenous growth factors (Example: glucocorticoids)
Evidence or history of an intracranial mass (e.g., pituitary tumor, craniopharyngioma)
Suspicion of absent pituitary function as evidenced by a maximal stimulated GH ≤ 3 ng/mL on two prior standard of care GH stimulation tests, or pituitary deficiencies beyond GH and thyroid function
BMI > 95th percentile
Malnutrition as evidenced by medical history or a body weight < 3rdth percentile for current height
Gestational age-adjusted birth weight < 5th percentile (small for gestational age)
History of spinal, cranial, or total body irradiation
Treatment with medications known to act as moderate or strong inhibitors or strong inducers of CYP3A/4, or with medications known to act as strong inhibitors of P-glycoprotein (P-gp) or potent substrates of P-gp or Multidrug and toxin extrusion protein 1 (MATE1)
