- How to Read a Study Record
In 2010, more than 35,000 people died in the United Kingdom from lung cancer, the majority from non-small cell cancer (NSCLC). Chemotherapy is one of the main treatments for patients with NSCLC but those treated will still only live for an average of 9 or 10 months after diagnosis.
The purpose of this clinical trial is to find out whether or not giving a drug called Olaparib following chemotherapy will benefit patients with NSCLC who have responded to initial chemotherapy treatment by prolonging the time before the tumour regrows. Olaparib is a new, oral drug developed by AstraZeneca which may help to slow down cancer growth. The rationale for this clinical trial is that chemotherapy damages tumour cell DNA and NSCLC tumours that respond to chemotherapy are less able to repair this damage. This can be exploited by using Olaparib as it blocks an enzyme called Poly (ADP-ribose) polymerase (PARP) which is essential for DNA repair. This will prevent DNA repair and cause cancer cell death by a mechanism known as synthetic lethality. Synthetic lethality arises when a combination of mutation in two or more genes leads to cell death.
Up to 300 patients who are to receive standard chemotherapy treatment will be initially registered into the trial. Of these patients, 114 patients who have responded to chemotherapy will be randomly allocated to receive either Olaparib or an inactive dummy pill or placebo by mouth. The trial will assess whether Olaparib delays disease progression following standard chemotherapy treatment in patients. It will also show whether the side effects of adding Olaparib following standard treatment are acceptable.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Non-small Cell Lung Cancer | Drug: Olaparib Other: Placebo | Phase 2 |
This is a multicentre randomised phase II trial. Patients are initially registered either before or during induction chemotherapy, their response to which will be used to determine whether they are eligible for randomisation. All patients will be asked to consent to archival tissue collection for translational analysis and to provide a translational blood sample. The second consent will precede randomisation to one of two groups of maintenance therapy (olaparib or placebo) with 1:1 randomisation if they have had an objectively measured complete or partial response following standard chemotherapy.
Randomised patients will receive olaparib or placebo until disease progression. They will be monitored by CT scan every two cycles until disease progression, where they will be managed according to local practice. Follow up will be for a maximum of 12 months from the point of randomisation or until disease progression.
All randomised patients for whom we have a baseline translational blood sample will be asked to provide a follow up blood sample upon randomisation and again at radiological progression. Registered patients with progressive disease after the initial induction chemotherapy will be asked to provide a follow-up blood sample at the end of induction chemotherapy.

Active Comparator: Olaparib
3 100mg tablets to be administered twice a day with approximately 240ml of water.

Drug: Olaparib
Olaparib is a potent inhibitor of poly (ADP-ribose) polymerase enzyme (PARP), (molecular weight 434) that is being developed as a monotherapy as well as for combination with chemotherapy and other anti-cancer agents. Olaparib can lead to tumour regression in patients with DNA repair deficient NSCLC. Olaparib may also enhance the DNA damaging effects of chemotherapy.

- Progression-free survival [ Time Frame: 72 weeks ]To establish the anti-tumour activity of Olaparib (measured by progression free survival),we will document the time from randomisation to any disease progression and/or death, defined according to strict RECIST (Response Evaluation Criteria in Solid Tumours) v1.1. Lesions will be compared to baseline measurements to assess progression.
- Safety [ Time Frame: 72 weeks ]An Independent Data Monitoring Committee will convene and assess safety when 10 and 20 patients on each arm have completed trial treatment. If the trial is deemed safe to continue then safety will be assessed again approximately every six months. Toxicity data will be assessed along with serious adverse events.
- Objective response rate [ Time Frame: 72 weeks ]This will be assessed based on radiological disease progression defined according to RECIST (Response Evaluation Criteria in Solid Tumours) v1.1.
- Overall survival [ Time Frame: 72 weeks ]This will be calculated from the time of randomisation to date of death or date last known to be alive.
- Change in tumour volume reduction [ Time Frame: 27 weeks ]Change in tumour volume reduction from randomisation to 6 months
- Tolerability [ Time Frame: 72 weeks ]This will be assessed in terms of the number of treatment reductions, delays and withdrawals.
- Feasibility [ Time Frame: 72 weeks ]Patients will complete a diary card every day to document compliance. Feasibility of use will also be assessed in terms of number of treatment reductions, delays and withdrawals.

- Histological diagnosis of NSCLC. Histology can be either squamous or non-squamous.

- Have had no prior systemic chemotherapy for advanced NSCLC. Previous adjuvant or neoadjuvant chemotherapy for non-advanced disease is acceptable. Prior treatment with an oral targeted therapy for e.g. EGFR/ALK or other driver- oncogene mutated lung cancer is allowed. Immunotherapy e.g. with a PD1 or PDL1 targeted agent is allowed.
