Non-Small Cell Lung Cancer
Conditions
Brief summary
This open-label, randomized, parallel arm study assessed the efficacy and safety of Tarceva (erlotinib) versus gemcitabine/cisplatin combination chemotherapy as first-line treatment in patients with stage IIIB/IV non-small cell lung cancer with epidermal growth factor receptor (EGFR) mutations in their tumours. Patients were randomized to receive either Tarceva 150 mg orally daily or 3-week cycles of gemcitabine 1250 mg/m\^2 intravenously (iv) on Days 1 and 8 plus cisplatin 75 mg/m\^2 iv on Day 1.
Interventions
Erlotinib was supplied as tablets.
Cisplatin and gemcitabine were locally sourced with commercial products.

| Measure | Time frame | Description |
|---|---|---|
| Investigator-assessed Duration of Progression-free Survival | Baseline to the data cut-off date of 20 Jul 2012 (1 year, 4 months) | The duration of progression-free survival was defined as the time from randomization to disease progression (PD) or death from any cause, whichever occurs first. PD was defined as: (1) At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this may include the baseline sum). The sum must also demonstrate an absolute increase of at least 5 mm. (2) An unequivocal progression of existing non-target lesions. When the patient has measurable disease, the overall tumor burden must have increased sufficiently to merit discontinuation of therapy. When the patient has only non-measurable disease, the increase in overall disease burden should be comparable in magnitude to the increase that would be required to declare PD for measurable disease. (3) The appearance of new malignant lesions. |

A CR was defined as the disappearance of all target lesions (TL).

SD was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD), taking as reference the smallest SLD since treatment started. For non-TLs, SD was defined as the persistence of 1 or more lesions. PD was defined as at least a 20% increase in the SLD of TLs, taking as reference the smallest SLD recorded since treatment started or the unequivocal progression of existing non-TLs. A SLD for all TLs will be calculated and reported as the Baseline SLD. |

(2) The disappearance of all non-target lesions and normalization of tumor marker levels. All lymph nodes must be non-pathological in size (\< 10 mm in the short axis). A PR was defined as: (1) At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum of diameters.
