Please assess the completion status of the following clinical trial:

Trial Title: First Line Treatment in EGFR Mutation Positive Advanced NSCLC Patients with Central Nervous System (CNS) Metastases

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: NONE
- Phase: PHASE2/PHASE3
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~1. Properly completed patient informed consent~2. Male or female aged at least 18 years~3. Histologically or cytologically confirmed diagnosis of NSCLC with activating EGFR mutations including L858R and/or Exon19Del. EGFR mutation status will be determined by local or central laboratory testing on tumour tissue or plasma utilizing a validated methodology which has been approved by the regulatory authority.~4. No prior treatment with chemotherapy, EGFR-TKIs, or biological therapies that are considered first line treatment for advanced NSCLC.~5. All patients must have a documented diagnosis of advanced (Stage IV) NSCLC with Magnetic Resonance Imaging (MRI) documented CNS metastases that include brain metastases (BM). BM + patients with co- existent leptomeningeal involvement are eligible for the study.~6. Eligible patients are not candidates for definitive surgical resection or radiation of all lesions in the opinion of the treating physician.~7. All patients must be stable without any systemic (oral or parenteral) corticosteroid or anticonvulsant therapy for at least 2 weeks prior to study treatment. Inhaled non-absorbable and topical corticosteroid use are permitted as indicated.~8. Patients may have prior placement of a properly functioning CNS shunt or Ommaya reservoir.~9. Eastern Cooperative Oncology Group (ECOG) performance status 0 to 1 with no deterioration over the previous 2 weeks.~10. Women of child-bearing potential and male subjects shall agree to take medically acceptable contraception measures while on study treatment and for 3 months following completion of study treatment. All women of child-bearing potential must have a negative blood pregnancy test at screening.~11. (a) For Patients with measurable CNS lesions must have AT LEAST ONE site of CNS lesion, which was not previously irradiated, that can be accurately measured at baseline as ≥ 10 mm in the longest diameter by MRI and which is suitable for accurate repeated measurements. Measurable extracranial disease is not required. (b) For Patients with non-measurable CNS lesions must have AT LEAST ONE extracranial lesion, which has not been previously irradiated, within the screening period that can be accurately measured at baseline as ≥ 10 mm in the longest diameter (except lymph nodes which must have short axis ≥ 15 mm) by CT/MRI and are suitable for accurate repeated measurement.
