Brief Summary:
This is a study of the safety and tolerability of oral miransertib (MK-7075) administered to participants at least 2 years of age with phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA)-related overgrowth spectrum (PROS) or Proteus Syndrome (PS). This is an extension of other miransertib studies (MK-7075-002 [NCT03094832] or ArQule CU/EAP [NCT03317366]), and may also enroll participants who are approved for MK-7075-002 but have not yet started miransertib therapy.

Arm Intervention/treatment
Experimental: Miransertib
Participants with either PROS or PS receive miransertib orally once daily between 5 and 35 mg/m^2 based on prior approved dosing for up to 48 cycles. A cycle is 28 days long.
Drug: Miransertib
Miransertib capsules administered orally either 1 hour before or 2 hours after a meal.
Other Names:
  • MK-7075
  • ARQ 092

Primary Outcome Measures :
  1. Number of participants experiencing a Serious Adverse Event (SAE) [ Time Frame: Up to approximately 4 years ]
    An SAE is defined as any untoward medical occurrence associated with the use of a drug in a participant, whether or not considered drug related. An SAE can therefore be any such event that results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalizations, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, or is considered by the investigator to be an important medical event.

  2. Number of participants discontinuing study treatment due to an Adverse Event (AE) [ Time Frame: Up to approximately 4 years ]
    An AE is defined as any untoward medical occurrence associated with the use of a drug in a participant, whether or not considered drug related. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product and does not imply any judgment about causality.
