Clinical Trial Summary

This is a multicentre randomised double-blind phase II trial, sponsored by Gustave Roussy and involving one French center as well as the Spanish Lung Cancer Group (≈20 centers of the SLCG).

Six hundred patients with diagnosis of stage IIIB/IV NSCLC will initially be registered prior to receiving the first line platinum-based chemotherapy or during or at the end of the first 6 cycles of inducation platinium based chemotherapy and provide consent for retrieving archival tissue collection and providing translational blood samples and tumor biopsies.

1. - Induction chemotherapy phase All patients will initially be treated with 6 cycles of platinum-based induction chemotherapy. Cycle duration will be 21 days. Doublets should either consist of a pemetrexed-platinum (cisplatin or carboplatin) doublet (preferentially for non-squamous NSCLC) or a gemcitabine - or vinorelbine - platinum doublet for squamous NSCLC. Taxanes-platinum doublets will not be accepted. Translational blood samples will be taken at the beginning of induction chemotherapy for all patients.

Patients displaying progressive disease or stable disease after induction chemotherapy will be withdrawn and further optimally managed according to local practice. For them, an optional tumour biopsy will be performed at the end of the induction treatment.

2. - Randomisation and maintenance phase Only patients who respond to platinum-based induction chemotherapy will be further randomised between olaparib and placebo. These patients must have been treated with 6 cycles of chemotherapy. However, patients who haven't received 6 cycles of the induction chemotherapy due to severe toxicity (grade 3 or 4, NCI CTCAE v4.0) could be randomized only if they had received 4 chemotherapy cycles at least and if all treatment related toxicities are resolved to a grade ≤ 1 (NCI CTCAE v4.0).

Treatment will be administered at a dose of 600 mg daily (2 doses of 300 mg [2 tablets of 150 mg] taken approximately 12 hours apart) and cycle duration will be 28 days. Disease will be assessed every 2 cycles by CTscan (MRI or PET-scan if the scan is not contributive) and treatment will be administered until disease progression or unacceptable toxicity. Patients will then be optimally managed according to local practice. Follow-up will be for a minimum of 15 months from the time of randomization, and until last venue. All randomised patients will be asked to provide translational blood samples at randomization, on treatment and at the end of the treatment. Optional tumour biopsies will be performed at randomization, at the end of the treatment (or at disease progression if available).

5. Advanced or metastatic disease (stage IIIB/IV)

6. Access to the original tumor biopsy or planning of a fresh tumor biopsy before start the platinium based chemotherapy

7. Chemonaive for NSCLC or patient having received adjuvant chemotherapy at least 2 years before trial enrolment or patient currently receiving his/her first platinum-based chemotherapy for advanced NSCLC (first line or second line only if the first line was an anti-PD-1 or anti-PD-L1 agent monotherapy)

8. No other cancer in the previous 3 years, except cervical cancer or cutaneous cancer

9. Absence of EGFR-sensitising mutation or ALK translocation

10. ECOG Performance Status of 0-1

11. Fit to receive 6 cycles or currently receiving of platinum-based induction chemotherapy

12. At the start of the platinium based induction chemotherapy measurable lesions by RECIST v1.1 criteria, i.e. at least one lesion, not previously irradiated, that can be accurately measured at baseline as = 10mm in the longest diameter (except lymph nodes that must have short axis = 15mm) with computed tomography (CT), magnetic resonance imaging (MRI) or clinical examination and which is suitable for accurate repeated measurements.

Inclusion criteria 13 is only for patients registered before starting the platinum-based induction chemotherapy:

13. Patients must have normal organ and bone marrow function measured within 14 days prior to administration of the platinum based treatment

• Haemoglobin = 10.0 g/dL

• Absolute neutrophil count (ANC) = 1.5 x 109/L

• Platelet count = 100 x 109/L

• Total bilirubin = 1.5 x institutional upper limit of normal (ULN)

• AST (SGOT)/ALT (SGPT) = 2.5 x institutional upper limit of normal unless liver metastases are present in which case it must be = 5x ULN

• Creatinine clearance > 60mL/min as calculated by Cockroft-Gault formula for cisplatin administration; creatinine clearance >/= 51mL/min by Cockroft-Gault formula for carboplatin administration

14. Evidence of non-childbearing status for women of childbearing potential: negative serum pregnancy test within 14 days of study treatment.

Postmenopausal is defined as:

• Amenorrheic for 1 year or more following cessation of exogenous hormonal treatments,

• LH and FSH levels in the post-menopausal range for women under 50,

• Radiation-induced oophorectomy with last menses >1 year ago,

• Chemotherapy-induced menopause with >1 year interval since last menses,

• Or surgical sterilisation (bilateral oophorectomy or hysterectomy).

15. Both men and women (of childbearing potential) who are sexually active should accept to use adequate contraception, during and for at least 6 months post-treatment

16. Patient is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow up.

17. Previous surgery (in the adjuvant setting) for NSCLC, radiotherapy (with a curative intent for local or locally-advanced disease) or immunotherapy by anti- PD-1 or anti-PD-L1 agent in the metastatic setting are allowed

Non-inclusion criteria:

1. Uncontrolled or symptomatic brain metastases. Controlled brain metastases are defined as stable for 1 month. A scan to confirm the absence of brain metastases is not required. Corticosteroids therapy will be allowed if administered at a stable dose for at least one month before entering the trial.

The patient can receive a stable dose of bisphosphonates for bone metastases, before and during the study as long as these were started at least 4 weeks prior to inclusion.
