• Accepts Healthy Volunteers: No
• Genders Eligible for Study: All

Description

Inclusion Criteria:

• Subject must have cytologically or histologically confirmed non-small cell lung cancer
• Subject must have brain metastases demonstrated on a magnetic resonance imaging (MRI) brain scan.
• Subject must be eligible for treatment with WBRT
• Subject must have had adequate hematologic, renal, and hepatic function.

Exclusion Criteria:

• Subject is diagnosed with brain metastases greater than 28 days prior to Day 1
• Subject received any prior form of cranial radiation and/or neurosurgery for their brain metastases
• Subject's last dose of anti-cancer therapy or investigational therapy was less than or equal to 7 days prior to Day 1
• Subject has a Karnofsky Performance Score of less than 70
• Subject has significant dyspnea requiring supplemental oxygen therapy
• Subject has liver metastases (restaging is not required for known liver metastases)

• Subject has leptomeningeal metastases or subarachnoid spread of tumor
• Subject has unresolved or unstable, serious toxicity from prior administration of another investigational drug and/or prior anti-cancer treatment
• Subject has a known seizure disorder that is uncontrolled, or has seizures occurring greater than or equal to 3 times a week over the past month. Subjects presenting with symptoms of seizures from the brain metastases are eligible; however he/she should receive adequate anti-seizure medication prior to study treatment
• Subject is pregnant or lactating
• Subject has previously been treated with a poly-(ADP-ribose)-polymerase inhibitor as an investigational agent

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Overall Survival	Overall survival was defined as the number of days from the date of randomization to the date of death. All events of death were included, regardless of whether the event occurred while the participant was still taking study treatment or after treatment was discontinued. If a participant had not died, the data were censored at the date the participant was last known to be alive.	From randomization up to 36 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Best Tumor Response Rate	Best tumor response rate was calculated as the percentage of participants with a complete response or partial response, as determined by brain scan imaging (magnetic resonance image or computed tomography) by a central imaging vendor. Response was assessed according to the modified bidimensional criteria: Complete response required all of the following: complete disappearance of all target and non-target lesions sustained for at least 4 weeks; no new lesions, including no new leptomeningeal disease; no systemic corticosteroid dose. Partial response required all of the following: ≥ 50% decrease compared with baseline in the size of all target lesions sustained for at least 4 weeks; no new lesions, including no new leptomeningeal disease and no unequivocal progression of non-target lesions, which, even in presence of stable disease or progressive disease in target lesions, was significant enough to qualify as progression; stable or reduced daily total systemic corticosteroid dose.	From randomization up to 24 months
Time to Intracranial Progression (Radiographic)	Time to intracranial progression (radiographic) was defined as the number of days from the date of randomization to the date of the first intracranial progression, as determined by brain scan imaging (magnetic resonance image [MRI]/ computed tomography [CT] scan) by a central imaging vendor. All confirmed events of intracranial progression were included, regardless of whether the event occurred while the participant was still taking study treatment or had previously discontinued study treatment. If the participant did not have a confirmed event of intracranial progression, their data were censored at the date of the last available intracranial progression assessment. Time to intracranial progression (radiographic) was estimated for each treatment group using Kaplan-Meier methodology.	From randomization up to 24 months
Time to Clinical Brain Metastasis Progression	Time to clinical brain metastases progression was defined as the number of days from randomization to the date of the first experience of clinical brain metastases progression, as assessed by a team of neuro-oncology experts (Event Review Board). All events of clinical brain metastasis progression were included, regardless of whether the event occurred while the participant was still receiving study treatment or had previously discontinued study treatment. If a participant did not have an event of clinical brain metastases progression, their data were censored at the date of the last available clinical disease progression assessment. Time to clinical brain metastasis progression was estimated for each treatment group using Kaplan-Meier methodology.	From randomization up to 24 months
