About this study
Official title: A Phase Ib Study of AZD1775 and Olaparib in Patients With Refractory Solid Tumours
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
Read the 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.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.

The PK sub-study must be initiated 10 days prior to the Cycle 1 Day 1 administration of the AZD1775 and olaparib combination. The patient will experience a short gap in treatment (approximately 4-5 days) between Day 3 of the olaparib PK sub-study and Cycle 1 Day 1 AZD1775 and olaparib combined dosing. |

Primary outcome
Part A: The incidence of dose-limiting toxicities (DLTs)
Time frame: 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.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing AZD1775 and Olaparib in people with Refractory Solid Tumours and Relapsed Small Cell Lung Cancer (SCLC), run by AstraZeneca at 6 sites in 2 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 19 inclusion and 30 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 7 Nov 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 6 sites in United States, Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Part A: The incidence of dose-limiting toxicities (DLTs) (time frame: 21 days (Cycle 1 duration)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02511795, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Nov 2019; AzTrials last refreshed its copy on 6 Nov 2026.
