Brief Summary:

It was found that people who have an excessive growth in one or more parts of their body and normal growth in other parts, may have a change in genes responsible for controlling cell growth. This genetic discovery identified a possible treatment for this overgrowth, called Sirolimus.

This is a pilot study, which help the investigators prepare a larger international study, which will aim to determine whether a treatment based Sirolimus is able to stop the excessive growth of one or more parties of their body in people who carry a genetic change in the PIK3CA gene (phosphatidylinosilol-3-kinase encoded by the gene PIK3CA).


Condition or disease Intervention/treatment Phase
Segmental Overgrowth Disorders Due to PIK3CA Drug: Sirolimus Phase 2

Detailed Description:

The duration of participation is 15 months:

  • Visit screening: blood test, pre-clinical evaluation, urine collection and chest X-ray.
  • First 6 months: participants will have their overgrowth monitored. This step includes 2 visits taking place at the University Hospital of Dijon: complete clinical evaluation, MRI of the body part by the overgrowth and Dual-energy X-ray absorptiometry (DXA).
  • Next 6 months: participants will take Sirolimus. This step includes 2 visits (4 and 13 weeks after the start of treatment at local hospital): blood test, urine collection and clinical evaluation.

and 1 end of study visit after 6 months of treatment taking place at the University Hospital of Dijon: blood test, complete clinical evaluation, urine collection, MRI and DXA.

Participants will have several blood and urine tests between visits (1 and 2 weeks after the start of treatment at a local laboratory).

Drug Information available for: Sirolimus


Intervention Details:
  • Drug: Sirolimus
    Low dose sirolimus will be given in daily dosing to achieve trough levels of 2-6 ng/ ml.


Primary Outcome Measures :
  1. Measure of the relative percentage of the excess tissue volume evolution at the affected site by volumetric MRI. [ Time Frame: Change from baseline at 6 and 12 months ]

Secondary Outcome Measures :
  1. Measure sites of overgrowth by DXA, MRI and circumferential measurements [ Time Frame: Change from baseline at 6 and 12 months ]
  2. To determine optimal sirolimus dosing algorithms by plasma assay [ Time Frame: 12 months ]
  3. Number of hospitalisation and surgery [ Time Frame: 12 months ]
  4. quality of life measured by a questionnaire in the pre- and post-treatment periods [ Time Frame: At 6 and 12 months ]
    The WHO-QOL-BREF questionnaire will be used for adults. For children, PedsQL™ questionnaire for children and parents report for children questionnaires will be used
