  • Brain metastases must be asymptomatic or treated and stable off steroids and anti-convulsants for at least 1 month prior to study treatment.
  • At least 1 lesion, not previously irradiated, that can be accurately measured at baseline (per RECIST v 1.1 guidelines)
  • Life expectancy of at least 8 weeks.
  • WHO/ ECOG PS of 0-1 at enrollment.

Inclusion criteria (Arm A specific)

Exclusion criteria (applicable to all arms):

  • Participation in another clinical study, major surgery, radiation therapy within 28 days.
  • Any condition that, in the opinion of the Investigator, would interfere with the evaluation of the IP or interpretation of patient safety or study results.
  • Uncontrolled intercurrent illness, including but not limited to interstitial lung disease.
  • History of another primary malignancy, leptomeningeal carcinomatosis or spinal cord compression.

Exclusion criteria (Arm A specific)

  • Active autoimmune disease, including a paraneoplastic syndrome.
  • Active or prior documented autoimmune or inflammatory disorders.
  • Any unresolved toxicity (CTCAE Grade >2) from previous anticancer therapy.
  • Active infection including tuberculosis, HIV, Hepatitis B or C.

Exclusion criteria (Arm B specific)

  • Prior exposure to any WEE1 inhibitors.
  • Products known to be sensitive to CYP3A4 substrates or CYP3A4 substrates with a narrow therapeutic index, or to be moderate to strong inhibitors/inducers of CYP3A4. Co-administration of rosuvastatin, atorvastatin, simvastatin and lovastatin, aprepitant or fosaprepitant or any herbal preparations. Grapefruit and Seville oranges should be avoided while taking AZD1775.
  • Any known hypersensitivity or contraindication to IP or CBDP.
  • QTcF > 470 msec or congenital long QT syndrome.
  • Any current or within 6 months cardiac diseases NYHA Class 2: unstable angina pectoris, congestive heart failure, acute MI, conduction abnormality not controlled with pacemaker or medication, significant ventricular or supraventricular arrhythmias.
  • A recent history of Torsades de pointes.

Exclusion criteria (Arm C specific)

  • Cytotoxic chemotherapy within 21 days of Cycle 1 Day 1 is not permitted
  • Previous treatment with a PARP inhibitor (including olaparib) or ATR inhibitor
  • Concomitant use of known strong CYP3A inhibitors and moderate CYP3A inhibitors
  • Concomitant use of known strong and moderate CYP3A inducers
  • Persisting (> 4 weeks) severe pancytopenia due to previous therapy
  • Cardiac dysfunction
  • Refractory nausea and vomitting, chronic gastrointenstinal diseases or previous significant bowel resection
  • Patients with uncontrolled seizures
  • Intenstinal obstruction or CTCAE grade 3 or grade 4 GI bleeding within 4 weeks before dosing
