-Radiotherapy with a wide field of radiation within 4 weeks(wks) before start of study treatment (capivasertib/placebo)
-Major surgery (excl.placement of vascular access,transurethral resection of prostate,bilateral orchiectomy,internal stents) within 4 wks of start of study treatment
-Brain metastases,or spinal cord compression (unless spinal cord compression is asymptomatic, treated and stable and not requiring steroids for at least 4 wks prior to start of study treatment)
-Past medical history of interstitial lung disease,drug-induced interstitial lung disease,radiation pneumonitis which required steroid treatment,or any evidence of clinically active interstitial lung disease
-Any of the following cardiac criteria:
i.Mean resting corrected QT interval (QTc) >470 msec from 3 consecutive ECGs
ii.Any clinically important abnormalities in rhythm, conduction or morphology of resting ECG
iii.Any factors that increase the risk of QTc prolongation or risk of arrhythmic events such as heart failure,hypokalaemia,potential for torsades de pointes,congenital long QT syndrome,family history of long QT syndrome or unexplained sudden death under 40 years of age,or any concomitant medication known to prolong the QT interval
iv.Clinically significant heart disease as evidenced by myocardial infarction, or arterial thrombotic events in the past 6 months,severe or unstable angina,or NYHA or Class II to IV heart failure or cardiac ejection fraction measurement of <50%
v.Experience of any of the following procedures or conditions in the preceding 6months: coronary artery bypass graft,angioplasty,vascular stent,myocardial infarction,angina pectoris,congestive heart failure NYHA Grade =2
vi.Uncontrolled hypotension - systolic blood pressure <90 mmHg and/or diastolic blood pressure <50 mmHg
vii.Cardiac ejection fraction outside institutional range of normal or <50% (whichever is higher) as measured by echocardiogram (or multiple-gated acquisition scan if an echocardiogram cannot be performed or is inconclusive)
viii.Uncontrolled hypertension (SBP =160 mmHg or DBP =95 mmHg).
-Clinically significant abnormalities of glucose metabolism as defined by any of the following:
i.Patients with diabetes mellitus (MS) type 1 or MS type 2 requiring insulin treatment
ii.HbA1c =8.0% (63.9 mmol/mol)
-Inadequate bone marrow reserve or organ function
-As judged by the investigator, any evidence of severe or uncontrolled systemic diseases, including active bleeding diatheses,or known active infection including hepatitis B and C,and HIV
-Unevaluable for both bone and soft tissue progression as defined by meeting both of the following criteria:
i.a superscan of bone scan,and
ii.no soft tissue lesion that can be assessed by RECIST criteria
-Refractory nausea and vomiting, malabsorption syndrome,chronic gastrointestinal diseases, inability to swallow the formulated product or previous significant bowel resection,or other condition that would preclude adequate absorption of capivasertib
-Any other disease,metabolic dysfunction,physical examination finding,or clinical laboratory finding that,in the investigator’s opinion,gives reasonable suspicion of a disease or condition that contra-indicates the use of an investigational drug,may affect the interpretation of the results,render the patient at high risk from treatment complications or interferes with obtaining informed consent
-Evidence of dementia,altered mental status,or any psychiatric condition that would prohibit understa
