4. Participant with type I diabetes or not controlled type II based on FPG and HbA1c see inclusion criterion 7
5. Participant has a concurrent malignancy or malignancy within 3 years of study screening period, with the exception of adequately treated basal or squamous cell carcinoma non melanomatous skin cancer or curatively resected cervical cancer

11. Participant has impairment of gastrointestinal GI function or GI disease that may significantly alter the absorption of the study drugs
12. Participant has any other concurrent severe and/or uncontrolled medical condition that would in the investigators judgment contraindicate participation in the clinical study.

17. Participant is a nursing lactating or pregnant woman
18. Participant is a woman of child-bearing potential defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception during study treatment and at least for 1 week for alpelisib or 1 year for fulvestrant based on prescribing label after the last dose of each study drug whichever comes later.
Highly effective contraception methods include:
i) Total abstinence when this is in line with the preferred and usual lifestyle of the Participant. Periodic abstinence e.g calendar ovulation symptothermal postovulation methods and withdrawal are not acceptable methods of contraception
ii) Female sterilization have had surgical bilateral oophorectomy with or without hysterectomy total hysterectomy or bilateral tubal ligation at least 6 weeks before taking study treatment. In case of oophorectomy alone only when the reproductive status of the woman has been confirmed by follow up hormone level assessment
iii) Male sterilization at least 6 months prior to screening. For female Participants on the study the vasectomized male partner should be the sole partner for that Participant
iv) Placement of an intrauterine device IUD or intrauterine system IUS without hormonal component.
Use of oral estrogen and progesterone injected or implanted combined hormonal method of contraception or placement of an intrauterine device IUD or intrauterine system IUS or forms of hormonal contraception that have comparable efficacy failure rate Less than 1% for example hormonal vaginal ring or transdermal hormone contraception. In case of use or oral contraception women should have been stable on the same pill for a minimum of 3 months before taking study treatment.
Note: Women are considered postmenopausal and not of child bearing potential if they have had 12 months of natural spontaneous amenorrhea with an appropriate clinical profile i.e age appropriate history of vasomotor symptoms or have had surgical bilateral oophorectomy with or without hysterectomy total hysterectomy or bilateral tubal ligation at least 6 weeks before taking study treatment. In the case of oophorectomy alone only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of child bearing potential.
Participant is a sexually active male unwilling to use a condom during intercourse while taking study treatment, and for 1 week for alpelisib or 1 year for fulvestrant based on prescribing label after stopping each study drug whichever comes later. A condom is required for all sexually active male participants to prevent them from fathering a child AND to prevent delivery of study treatment via seminal fluid to their partner. In addition, male participants must not donate sperm during study and up to the time period specified above.

This is a Phase IV prospective multicenter open label non comparative interventional study to assess the safety of alpelisib plus fulvestrant, in men and post-menopausal women with HR positive HER2 negative aBC or MBC with a PIK3CA mutation whose disease has progressed on or after endocrine-based treatment.
The study will include a total of 100 participants. During the treatment phase, treatment will be administered as alpelisib 300 mg orally once daily dosing schedule starting on Cycle 1 Day 1 in combination with fulvestrant i.m. 500 mg on Cycle 1 Day 1 and Day 15 and Day 1 of every cycle thereafter ± 3 days in a 28 days cycle.
The planned duration of treatment is 6 months. Participants may be discontinued from treatment earlier due to unacceptable toxicity disease progression, or if treatment is discontinued at the discretion of the investigator or the participant. For participants who were ongoing on treatment at the end of the planned duration of study and, in the opinion of the investigator are still deriving clinical benefit from alpelisib every effort will be made to continue provision of study treatment via post trial access.
