Accurate Statements
FDA approved Koselugo (selumetinib) on April 10, 2020.
Not verifiable from the provided excerpts.
Koselugo (selumetinib) is a MEK inhibitor.
Supported by Clinical Pharmacology (Mechanism of Action): “Selumetinib is an inhibitor of mitogen-activated protein kinase kinases 1 and 2 (MEK1/2).”
Koselugo is approved for the treatment of pediatric patients aged 2 years and older with neurofibromatosis type 1 (NF1) who have symptomatic, inoperable plexiform neurofibromas.
Partially supported. The provided label excerpt states indication for “adult and pediatric patients 1 year of age and older” with symptomatic, inoperable plexiform neurofibromas (Indications and Usage (1)).
Unsupported Statements
FDA approved Koselugo (selumetinib) on April 10, 2020.
No approval/approval-date information was included in the provided label excerpts to confirm this date.
Koselugo is approved for the treatment of pediatric patients aged 2 years and older...
The provided label excerpt specifies pediatric patients 1 year of age and older (not 2 years and older). The '2 years and older' threshold is not supported by the excerpt.

AI Statement
Koselugo is approved for the treatment of pediatric patients aged 2 years and older with NF1 who have symptomatic, inoperable plexiform neurofibromas.
Label Reference
Indications and Usage (1) excerpt: “adult and pediatric patients 1 year of age and older...”
Important Omissions
The indication statement omitted that approval includes pediatric patients 1 year of age and older (not limited to ≥2 years) and also includes adults.
Importance:
Moderate
Safety Assessment
Potential Patient Risk:
Low
The response includes no dosing, contraindications, boxed warnings, monitoring, or safety claims from the label. The only potential label-alignment risk is an indication-age misstatement (2+ years vs. 1+ years), which could narrow appropriate labeling but is not a direct contraindication or dosing/safety error.

Recommendation

Primary Issue
Indication age threshold is misstated as ≥2 years instead of the label excerpt’s ≥1 year, and adults are omitted from the indication statement.
Suggested Improvement
Revise the indication to match the label excerpt: “adult and pediatric patients 1 year of age and older with NF1 who have symptomatic, inoperable plexiform neurofibromas.”
