Study Details

Study Description

Brief Summary

This is an open label, Phase 1/2 study of oral miransertib (MK-7075) administered to participants at least 2 years of age with PIK3CA-related Overgrowth Spectrum (PROS) and Proteus Syndrome (PS) (MOSAIC).

Condition or Disease Intervention/Treatment Phase
Phase 1/Phase 2

Detailed Description

The study consists of two parts: Part A and Part B. Part A was closed to enrollment under Amendment 6. As of Amendment 7, the endpoints for Part A and Part B have been combined to assess the safety and tolerability of miransertib in participants with PROS and PS. Previous efficacy and pharmacokinetic (PK) objectives and endpoints have been removed.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Part A: Miransertib PROS/PS

  • Outcome Measures

    Primary Outcome Measures

    1. Number of participants experiencing an Adverse Event (AE) [Up to approximately 51 months]

      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.

    2. Number of participants discontinuing study treatment due to an Adverse Event (AE) [Up to approximately 48 months]

      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.
