Brief Summary:

The study is a site-based retrospective non-interventional medical chart review of pediatric and adult male and female patients with PIK3CA-Related Overgrowth Spectrum (PROS). Patient-level data are abstracted from medical charts of all eligible patients at all participating sites.

Information from patients treated with alpelisib is used to describe the efficacy and safety of alpelisib in PROS patients.

  1. Proportion of patients with response (yes/no) at Week 24 (+/- 4 weeks) [ Time Frame: 24 weeks (+/- 4 weeks) ]
    Proportion of patients with response (yes/no) at Week 24 (+/- 4 weeks), defined by achieving at least 20% reduction from index date in the sum of measurable target lesion volume (1 to 3 lesions, via central review of imaging scans), provided that none of the individual target lesions have ≥ 20% increase from index date and in absence of progression of non-target lesions and without new lesions.


Secondary Outcome Measures :
  1. Percent change in the sum of measurable target lesion volume as measured by the change between the index date and key time-points following the index date [ Time Frame: 4, 12 , 24, 36, 52 weeks after starting the study treatment (index date) ]
    Percent change in the sum of measurable target lesion (1 to 3 lesions) volume, as assessed by a central review of imaging scans, as measured by the change between the index date (or up to 12 weeks prior) and key time-points following the index date

  2. Percent change in the sum of all measurable (target and non-target) lesion volume between the index date (or up to 12 weeks prior) and key time-points following the index date [ Time Frame: 4, 12 , 24, 36, 52 weeks after starting the study treatment (index date) ]
    Percent change in the sum of all measurable (target and non-target) lesion volume, as assessed by a central review of imaging scans, as measured by the change between the index date (or up to 12 weeks prior) and key time-points following the index date

    • PROS-related surgeries (e.g., de-bulking or vascular surgery as well as the intended site of the procedure)

  4. Change in PROS symptoms and complications over time [ Time Frame: 4, 12 , 24, 36, 52 weeks after starting the study treatment (index date) ]

  6. Change in health care resource use [ Time Frame: 4, 12 , 24, 36, 52 weeks after starting the study treatment (index date) ]

  7. Change in laboratory assessments [ Time Frame: 4, 12 , 24, 36, 52 weeks after starting the study treatment (index date) ]
