Eligibility Criteria

Inclusion

  • Pertinent Inclusion criteria:
  • Informed consent prior to any study specific procedures.
  • Male or female ≥18 years of age.
  • Progressive cancer at the time of study entry.
  • Histologically or cytologically confirmed TNBC at initial diagnosis with evidence of metastatic disease and HER2 negative as per ASCO-CAP HER2 guideline recommendations 2013.
  • Patients must have received at least 1 and no more than 2 prior lines of treatment for metastatic disease with an anthracycline (eg, doxorubicin, epirubicin) and/or a taxane (eg, paclitaxel, docetaxel) unless contraindicated, in either the neo-adjuvant, adjuvant or metastatic setting.
  • Confirmed presence of qualifying HRR mutation or absence of any HRR mutation in tumour tissue by the Lynparza HRR assay.
  • At least one measurable lesion that can be accurately assessed at baseline by computed tomography (CT) (magnetic resonance imaging \[MRI\] where CT is contraindicated) and is suitable for repeated assessment as per RECIST 1.1.
  • Patients must have normal organ and bone marrow function measured within 28 days prior to randomization (defined in the protocol).
  • ECOG PS 0-1 within 28 days of randomisation.
  • Postmenopausal or evidence of non-childbearing status for women of childbearing potential (contraception restrictions apply to participants and their partners).
  • 13\. Patient is willing to comply with the protocol requirements. 14. Life expectancy of ≥16 weeks.
  • Pertinent Exclusion criteria:
  • Cytotoxic chemotherapy, hormonal or non hormonal targeted therapy within 21 days of Cycle 1 Day 1 is not permitted. Palliative radiotherapy must have been completed 21 or more days before Cycle 1 Day 1. The patient can receive a stable dose of bisphosphonates or denosumab for bone metastases, before and during the study as long as these were started at least 5 days prior to study treatment.
  • More than 2 prior lines of cytotoxic chemotherapy for metastatic disease (prior treatments with hormonal, non-hormonal, biologics or the combination of an aromatase inhibitor and everolimus are not counted as a prior line of therapy).
  • Previous randomisation in the present study.
  • Previous treatment with a PARP inhibitor (including olaparib) or other DDR inhibitor (unless less than 3 weeks duration and at least 12 months has elapsed between the last dose and randomization).
  • Exposure to a small molecule IP within 30 days or 5 half-lives (whichever is longer) prior to randomisation. The minimum washout period for immunotherapy shall be 42 days.
  • Patients with second primary cancer (exceptions defined in the protocol).
  • Mean resting corrected QTc interval using the Fridericia formula (QTcF) \>470 msec/female patients and \>450 msec for male patients (as calculated per institutional standards) obtained from 3 ECGs performed 2-5 minutes apart at study entry, or congenital long QT syndrome.
  • Any of the following cardiac diseases currently or within the last 6 months: unstable angina pectoris, congestive heart failure ≥ Class 2 as defined by the New York Heart Association, acute myocardial infarction, conduction abnormality not controlled with pacemaker or medication (patients with a conduction abnormality controlled with pacemaker or medication at the time of screening are eligible), significant ventricular or supraventricular arrhythmias (patients with chronic rate-controlled atrial fibrillation in the absence of other cardiac abnormalities are eligible).
  • Concomitant use of known strong or moderate cytochrome P (CYP) 3A inhibitors, strong or moderate CYP3A inducers, or sensitive CYP3A4 substrates or CYp3A4 substrates with a narrow therapeutic index (No longer applicable from CSPv7.0).
  • Persistent toxicities (≥ CTCAE grade 2) caused by previous cancer therapy, excluding alopecia and CTCAE grade 2 peripheral neuropathy.
  • Major surgery within 2 weeks of starting study treatment: patients must have recovered from any effects of any major surgery.
  • Immunocompromised patients, eg, human immunodeficiency virus (HIV).
  • Patients with known active hepatitis (ie, hepatitis B or C).
  • Patients considered a poor medical risk due to a serious, uncontrolled medical disorder, non malignant systemic disease or active, uncontrolled infection.
  • Patients with symptomatic uncontrolled brain metastases.
  • Patients unable to swallow orally administered medication and patients with gastrointestinal disorders likely to interfere with absorption of the study medication.
  • Patients with a known hypersensitivity to olaparib, adavosertib, Ceralasertib, or any of the excipients of the products.
  • Pregnant or breast feeding women.
