The Pharmacokinetics and Safety of Olaparib Alone and With Paclitaxel in Chinese Patients With Advanced Solid Tumour.

This is a 2 parts phase I, open label trial of olaparib monotherapy and olaparib in combination with paclitaxel in patients with solid tumours. Part A will assess the single and multiple dose pharmacokinetics of olaparib monotherapy and multiple dose pharmacokinetics of olaparib in combination with paclitaxel. Part B will assess the safety of multiple doses of olaparib in Cohort 1 and of olaparib when co-administered with paclitaxel in Cohort 2

About this study

Part A will access the pharmacokinetics of olaparib: Cohort 1 will investigate the single and multiple dose pharmacokinetics of olaparib following 300mg bd monotherapy dose(s); Cohort 2 will investigate the single and multiple dose pharmacokinetics of olaparib following 100mg bd monotherapy dose(s) and the multiple dose pharmacokinetics in the presence of co-administered paclitaxel (80mg/m2 weekly on days 1, 8 and 15 of a single 28-day cycle).

In Part B: Safety profile of olaparib 300mg bd as monotherapy and olaparib 100mg bd in combination with weekly paclitaxel will also be investigated in Chinese patients.

Inclusion criteria

  • Provision of fully informed consent
  • Patient aged ≥ 18 years
  • Histologically or, where appropriate, cytologically confirmed malignant solid tumour refractory or resistant to standard therapy and for which no suitable effective standard therapy exists
  • life expectancy of ≥ 12 weeks
  • Patients for Cohort 2 must be eligible for paclitaxel treatment
  • Willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations
  • ECOG performance status ≤ 2
  • Satisfactory organ and bone marrow function measured within 28 days prior to administration of study treatment including - Haemoglobin ≥ 10.0 g/dL and no blood transfusion in the 4 weeks prior to the first dosing of study drug. - Absolute neutrophil count ≥ 1.5 × 109/L
  • Evidence of non-childbearing status for women of childbearing potential, or postmenopausal status: negative urine or serum pregnancy test within 28 days of study treatment, confirmed prior to treatment on Day 1.
  • Patients must be on a stable concomitant medication regimen, defined as no changes in medication or in dose within 2 weeks prior to start of olaparib dosing, except for bisphosphonates, denosumab and corticosteroids, which should be stable for at least 4 weeks prior to start of olaparib dosing.

Exclusion criteria

  • Involvement in the planning and/or conduct of the study.
  • Previous enrolment in the present study.
  • Treatment with any investigational product during the last 14 days (or a longer period depending on the defined characteristics of the agents used).

  • Concomitant use of known potent CYP3A4 (Cytochrome P450 3A4) inhibitors.
  • Patients with any ongoing toxicities (>CTCAE (Common Terminology Criteria for Adverse Events) grade 2), with the exception of alopecia, caused by previous cancer therapy.
  • Resting ECG with QTc (Heart Rate Corrected QT interval) > 470msec or family history of long QT syndrome.
  • Patients with interstitial pneumonia or diffused symptomatic fibrosis of the lungs.
  • Patients with myelodysplastic syndrome/acute myeloid leukaemia.
  • Patients with symptomatic uncontrolled brain metastases.
  • Major surgery within 2 weeks of starting study treatment and patients must have recovered from any effects of any major surgery.
  • Patients considered a poor medical risk due to a serious, uncontrolled medical disorder, non-malignant systemic disease or active, uncontrolled infection.
  • Immunocompromised patients, e.g. patients who are known to be serologically positive for human immunodeficiency virus (HIV).
  • Patients with known active hepatic disease (i.e. Hepatitis B or C).
  • Patients with a known hypersensitivity to olaparib, paclitaxel or any of the excipients of the product.
  • Breastfeeding women.
  • Clinical judgement by the investigator that the patient should not participate in the study.
