Survival Results
Proven survival benefit in unselected patients with advanced NSCLC
- Tarceva (erlotinib) significantly improved overall survival, the primary endpoint, by 37% in patients with relapsed Stage IIIB/IV NSCLC vs placebo (P<0.001).1, 2
- median survival lengthened by 42.5% vs placebo (6.7 months vs 4.7 months)
- In the single-agent NSCLC Phase III trial, the hazard ratio (based on a log-rank test) was used prospectively to define the primary endpoint of overall survival. A hazard ratio <1.0 indicates Tarceva had a survival benefit.1
- Hazard ratio of 0.73 indicates a 27% reduction in risk of death for patients who received Tarceva.1, 2
Tarceva increased 1-year survival
- One-year survival with Tarceva was 31.2% vs 21.5% with placebo.1
Impact on time to progression and disease control rate
- Tarceva significantly prolonged progression-free survival by 69% in patients with relapsed Stage IIIB/IV NSCLC-hazard ratio of 0.59 indicates that the risk of death or disease progression was reduced by 41% (P<0.001).1
Disease control rate improved with Tarceva
- In the pivotal trial, BR.21, the disease control rate (CR+PR+SD) for patients receiving Tarceva was 44.0% vs 27.5% for placebo.1, 2
- The median duration of disease control was 6.0 months (95% CI=5.7-7.4; n=188) with Tarceva vs 4.7 months (95% Cl=3.7-5.5; n=58) for placebo (HR=0.53; P=0.0002).1, 2
Tarceva increased tumor response rate and lengthened median duration of response
- Tarceva significantly increased tumor response rate vs placebo (8.9% vs 0.9%, P<0.001).1
- In patients with a response to Tarceva, the median duration of response (CR+PR) was 7.9 months (n=38).1
Survival benefit in second-line, PS 0-1 patients
A retrospective analysis of patients by ECOG Performance Status (PS) and line of therapy.
- In a retrospective analysis of PS 0-1 patients receiving second-line Tarceva:2
- median survival was lengthened by 40% vs placebo (9.4 months vs 6.7 months)
- one-year survival rate was increased by 33% vs placebo (40% vs 30%)
- progression-free survival was significantly prolonged by 79% vs placebo (HR=0.56; 95% CI=0.42-0.75; P<0.001)

NSCLC efficacy overview
- Tarceva significantly prolonged overall survival by 37% (P<0.001).1
- Tarceva significantly prolonged progression-free survival by 69% - a hazard ratio of 0.59 indicates that the risk of death or disease progression was reduced by 41% (P<0.001).1
- In a retrospective analysis, Tarceva significantly prolonged overall survival for second-line, Performance Status (PS) 0-1 patients by 47% (HR=0.68; P=0.018) and lengthened median survival by 9.4 months vs 6.7 months for placebo.2
- Although the survival benefit extended to a diverse patient population, in a retrospective, exploratory subset analysis, Tarceva appeared to offer a greater relative survival benefit for EGFR positive (HR=0.68) and nonsmoking patients (HR=0.42)1
Survival benefit across diverse patient groups
Tarceva demonstrated a significant 37% improvement in overall survival in a large, randomized, placebo-controlled trial of unselected patients with advanced NSCLC.1
- In exploratory univariate analyses, the effect on survival was shown to be similar in most patient populations.1
- Some factors were associated with a greater response, but there are no known patient populations that would exclude a positive treatment effect.1
