Interventional(has expanded access)
Description of intervention(s) / exposure
Treatment: Drugs - Miransertib

Experimental: Part A: Miransertib PROS/PS - During Cycles 1-3, participants with either PROS (phosphatidylinositol- 4,5-bisphosphate 3-kinase, catalytic subunit alpha [PIK3CA]-related Overgrowth Spectrum) or PS (Proteus syndrome) received miransertib 15 mg/m^2 once daily (QD) (each cycle length = 28 days). From Cycles 4-48 or until disease progression, unacceptable toxicity, or discontinuation, participants received miransertib dose titrated to 25 mg/m^2 and then titrated to 35 mg/m^2 orally QD at the investigator's discretion.

Experimental: Part B: Miransertib PROS (Cohort 1) - During Cycles 1-3, participants with PROS who have a measurable lesion by volumetric magnetic resonance imaging (MRI) received miransertib 15 mg/m^2 QD (each cycle length = 28 days). From cycles 4-48 or until disease progression, unacceptable toxicity, or discontinuation, participants received miransertib dose titrated to 25 mg/m^2 orally QD at the investigator's discretion.

Experimental: Part B: Miransertib PS (Cohort 2) - During Cycles 1-3, participants with PS who have a measurable lesion by standardized digital photography received miransertib 15 mg/m^2 QD (each cycle length = 28 days). From cycles 4-48 or until disease progression, unacceptable toxicity, or discontinuation, participants received miransertib dose titrated to 25 mg/m^2 orally QD at the investigator's discretion.

Experimental: Part B: Miransertib PROS/PS (Cohort 3) - During Cycles 1-3, participants with PROS or PS who do not meet all the eligibility criteria for Cohorts 1 or 2 received miransertib 15 mg/m^2 QD (each cycle length = 28 days). From cycles 4-48 or until disease progression, unacceptable toxicity, or discontinuation, participants received miransertib dose titrated to 25 mg/m^2 orally QD at the investigator's discretion.

Experimental: Part B: Miransertib Compassionate Use/Expanded Access (Cohort 4) - During cycles 1-48 (each cycle length = 28 days) or until disease progression, unacceptable toxicity, or discontinuation, participants previously treated with miransertib or currently receiving miransertib under Compassionate Use/Expanded Access continued to receive the current dose of miransertib (did not exceed 25 mg/m^2).


Treatment: Drugs: Miransertib
Miransertib capsules administered orally at an initial dose of 15 mg/m^2 or 25 mg/m^2 QD and then titrated up to 25 mg/m^2 or 35 mg/m^2 QD at the investigator's discretion.
