Inclusion criteria
. Signed informed consent and assent (when applicable) from the patient, parent, or guardian must be obtained prior to any study related screening procedures are performed.
. Male or female patients age ≥2 years and ≤40 years at the time of informed consent
. Patients with diagnosis of MCAP\* with neurodevelopmental disorder presentation (from specific learning disorder to severe intellectual disability)
. Documented evidence of a postzygotic or constitutional mutation(s) in the PIK3CA gene performed in local laboratories using a Deoxyribonucleic acid (DNA) based validated test at the time of informed consent.
. Adequate bone marrow and organ function (assessed during the screening visit):
. Absolute neutrophil count ≥ 1.5 × 109/L
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Proportion of participants with response at end of treatment assessed by the Vineland II Adaptive Behavior Scale (VABS-II)
Timeframe: At 24 months of treatment compared to baseline
. Hemoglobin ≥ 9.0 g/dL (transfusions are allowed)
Exclusion criteria
. Patient previously treated with alpelisib
. Known impairment of GI function due to concomitant disease that may significantly alter the absorption of the study drug (e.g., ulcerative diseases, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, or small bowel resection) at time of informed consent.
. Participant with uncontrolled diabetes mellitus (Type I or II) at time of informed consent.
. History of hypersensitivity to any drugs or metabolites of PI3K inhibitor or any of the excipients of alpelisib at time of informed consent.
. Participant with other concurrent severe and/or uncontrolled medical conditions that would, in the treating Physician's judgment, contraindicate administration of alpelisib (e.g., active and/or uncontrolled severe infection, chronic active hepatitis, hepatic impairment Child Pugh score C, immuno-compromised, etc.) at time of informed consent.
. Female participants of childbearing potential and male participants who do not agree at time of informed consent to abstinence or, if sexually active, unwilling to use a condom and/or a highly effective method of contraception for the duration of the study and for one week following discontinuation of alpelisib. Highly effective contraception methods is one of the following:
. Total abstinence: when this is in line with the preferred and usual lifestyle of the subject. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception
. Female sterilization: have had surgical bilateral oophorectomy (with or without hysterectomy), total hysterectomy or bilateral tubal ligation at least six weeks before taking alpelisib. In case of oophorectomy alone, only when the reproductive status of the female has been confirmed by follow-up hormone level assessment
