Patient agrees to abstinence or highly effective contraceptive measures for males and women of childbearing potential (WOCBP) * Males who are sexually active must use a condom during intercourse while taking alpelisib and for at least 4 weeks after stopping alpelisib and should not father a child in this period. A condom is required to be used also by vasectomised men in order to prevent delivery of the drug via seminal fluid. In addition, male participants must not donate sperm during the study and for at least 4 weeks after stopping alpelisib * Females who are of child-bearing potential, defined as all women physiologically capable of becoming pregnant, must use a highly effective method of contraception during study treatment and for at least 1 week after the last dose of any study treatment. Highly effective contraceptive methods include: * Total abstinence (when this is in line with the preferred and usual lifestyle of the subject) Periodic abstinence (eg., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception; * Female sterilisation (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 women has been confirmed by follow up hormone level assessment; * Male partner sterilisation (at least 6 months prior to screening) of the sole partner of a female participant on the study; * 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 \< 1%), for example hormonal vaginal ring or transdermal hormone contraception. In the case of use of oral contraception, women should have been stable on the same pill for a minimum of 3 months before taking study treatment. * Women are considered postmenopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhoea 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 to be not of child bearing potential. 10.
