4 Patients must have normal organ and bone marrow function measured within 28 days prior to administration of investigational product (IP) as defined below: Haemoglobin (Hb) greater than or equal to 10.0 g/dL, with no blood transfusions in the previous 28 days.

10. Patients must be on a stable concomitant medication regimen (with the exception of electrolyte supplements), defined as no changes in medication or in dose within the 2 weeks prior to start of olaparib dosing, except for bisphosphonates, denosumab, and corticosteroids, which should be at a stable dose for at least 4 weeks prior to the start of olaparib dosing.
