AZD1775 Combined With Olaparib in Patients With Refractory Solid Tumors

Phase 1
Completed
Conditions
Refractory Solid Tumours
Relapsed Small Cell Lung Cancer (SCLC)
Interventions
Registration Number
NCT02511795
Lead Sponsor
AstraZeneca
Brief Summary

The purpose of this Phase 1b, multi-centre, dose escalation study is to find the maximum tolerated dose (MTD) of AZD1775 combined with olaparib in patients with refractory solid tumours

Detailed Description

This is a Phase Ib, multi-centre study of AZD1775 combined with olaparib administered orally in patients with refractory solid tumours, or as combination therapy for relapsed small-cell lung cancer (SCLC). There are 2 parts to the study:

Part A: Dose Escalation Part B: Dose Expansion

In Part A, patients with refractory solid tumours will be assessed for safety, tolerability, and pharmacokinetics (PK) of AZD 1775 when combined with olaparib. Different dose levels will be administered to identify the maximum tolerated dose (MTD)/recommended phase 2 dose (RP2D).

The dose expansion part (Part B) will further explore the safety, PK, and preliminary efficacy of the AZD1775 RP2D and dosing schedule for the treatment of patients with SCLC who previously had a confirmed response (either a Complete Response or Partial Response) to first-line platinum therapy and then relapsed. Patients who progressed whilst on platinum-containing therapy (platinum refractory) are not permitted to enter the study..

An olaparib pharmacokinetic (PK) sub-study will precede the combined treatment with AZD1775 and olaparib for all patients in Part A. In the sub-study single agent olaparib will be given orally BID for 3 or 5 consecutive days and venous blood samples will be collected on Day 3 or Day 5 as appropriate for assessment of the multiple dose pharmacokinetics of single agent olaparib. Patients will experience a short gap in treatment (approximately 4-5 days) between Day 3 or Day 5 of the olaparib PK sub-study and Cycle 1 Day 1 of the combination treatment.

Patients will continue to receive treatment with AZD1775 and Olaparib until disease progression, intolerable toxicity, or discontinuation criteria have been met.

Primary Outcome Measures
NameTimeMethod
Part A: The incidence of dose-limiting toxicities (DLTs)21 days (Cycle 1 duration)

The maximum tolerated dose (MTD) of the AZD1775/olaparib combination will be the highest dose level at which less than one-third of patients experience a DLT during Cycle 1. Toxicity will be graded according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) v4.03.

Part B: The incidence of treatment-emergent adverse events (TEAEs)Up to 12 months

Treatment-emergent adverse events will be assessed through reports of clinical events and changes from baseline in vital signs and laboratory parameters.

Secondary Outcome Measures
NameTimeMethod
Part A: QTc IntervalPre-dose and at pre-specified times on Day 1 and 3 (or 5) of the olaparib PK sub-study, prespecified times on Days 1, 3, and 10 (or 1, 5, and 12) of Cycle 1, and pre-specified times on Days 1 and 3 (or 1 and 5) of Cycle 2, up to 9 weeks.

Triplicate 12-lead ECGs will be performed approximately 2-5 minutes apart. The QTc interval will be calculated using Friderica's formula.

Objective Response Rate (ORR)Through study completion (an average of 6 months)

The objective response rate (ORR) is the number of patients with a confirmed best objective response of Complete Response (CR) or Partial Response (PR) divided by the number of patients in the full analysis set with measurable disease at baseline. ORR is determined by the Investigator in accordance with Response Evaluation Criteria in Solid Tumors (RECIST) v1.1.

Disease Control Rate (DCR)Through study completion (an average of 6 months)

Disease Control Rate (DCR) is defined (RECIST v1.1) as the percentage of patients in the full analysis set with a confirmed best objective response of complete response (CR), partial response (PR), or a best objective response of stable disease (SD).
