What was measured

Objective response rate was defined as the percentage of participants who achieved a complete response (CR) or partial response (PR) within the first 6 cycles of treatment (or within 3 cycles for participants in the DIPG group). Disease assessments were based on MRI and assessed by an independent central review. CR: Disappearance of all lesions and no new lesions. PR: A reduction of ≥ 50% in the size of measurable lesions compared to baseline, and/or the persistence of non-target lesions with no progression or decrease in size. Progressive Disease (PD): ≥ 25% increase in the size of the measurable lesions, or the appearance of one or more new lesions and/or unequivocal progression of existing non-target lesions.

Analysis population: The response population consisted of all enrolled participants receiving at least one cycle of pomalidomide if therapy was not discontinued earlier due to progressive disease (PD)

Groups in this outcome

Diffuse Intrinsic Pontine Glioma

Participants received 2.6 mg/m²/day oral pomalidomide on days 1 to 21 of each 28-day treatment cycle for up to 24 cycles or until disease progression, withdrawal of consent/assent, treatment became intolerable, or death, whichever occurred first.

Ependymoma

Participants received 2.6 mg/m²/day oral pomalidomide on days 1 to 21 of each 28-day treatment cycle for up to 24 cycles or until disease progression, withdrawal of consent/assent, treatment became intolerable, or death, whichever occurred first.

High-grade Glioma

Participants received 2.6 mg/m²/day oral pomalidomide on days 1 to 21 of each 28-day treatment cycle for up to 24 cycles or until disease progression, withdrawal of consent/assent, treatment became intolerable, or death, whichever occurred first.

Medulloblastoma

Participants received 2.6 mg/m²/day oral pomalidomide on days 1 to 21 of each 28-day treatment cycle for up to 24 cycles or until disease progression, withdrawal of consent/assent, treatment became intolerable, or death, whichever occurred first.
