Overview
ADJUVANT TAGRISSO® transforms the treatment options of resectable EGFRm NSCLC1
Significantly improved overall survival1
-51 % reduced risk of death with ADJUVANT TAGRISSO® compared to the control arm in stage IB-IIIA
(HR=0.49 [95% CI: 0.34-0.70; P<0.0001])
Lower risk of recurrence2
-73 % reduced risk of recurrence or death with ADJUVANT TAGRISSO® compared to the control arm in stage IB-IIIA (HR=0.27 [95% CI: 0.21-0.34])
Fewer CNS recurrences and distant metastases2
-76 % reduced risk of brain metastases with ADJUVANT TAGRISSO® compared to the control arm in Stage II-IIIA (HR=0.24 [95% CI: 0.14-0.42])
-59 % reduction in the relative risk of distant metastases with ADJUVANT TAGRISSO® compared to the control arm (15% vs. 37%)
Study design
ADAURA: global phase III study in patients with resectable EGFRm NSCLC (IB-IIIA)2
Primary endpoint: Disease-free survival (DFS) in patients with NSCLC in stage II and IIIA (according to 7th AJCC edition*)
Secondary endpoints: DFS in the total population (stage IB-IIIA, according to 7th AJCC edition*), DFS after 2, 3, 4 and 5 years, overall survival, safety, health related quality of life.
- * AJCC 7th edition: Stage IIIA includes stage IIIB patients (T3 N2 M0) according to the 8th edition.
- † Centrally confirmed in tissue.
- ‡ According to guidelines, at the discretion of the physician. Prior, subsequent or planned radiation was not permitted. Neoadjuvant chemotherapy was not permitted.
- # Stratification factors: Stage (IB vs II vs IIIA), EGFRm (Ex19del vs L858R), ethnic ancestry (Asiatic vs non-Asiatic).
- DFS: Disease-free survival; EGFR: Epidermal growth factor receptor; NSCLC: Non-small cell lung cancer.

ADJUVANT TAGRISSO® significantly improves overall survival in stage IB-IIIA1
Data cut-off: January 27, 2023
Data maturity was 18 % at the time of analysis (osimertinib 12%, placebo 24%); Median follow-up for OS: osimertinib 60.4 months, placebo 59.4 months.
Adapted according to Tsuboi M, et al. 20231
OS: Overall survival; HR: Hazard ratio.
Safety
Known safety and tolerability profile of TAGRISSO® in ADAURA2
Reported adverse events of all causes (≥10% of patients)
Adapted according to Herbst R, et al. 20232
Data cut-off: April 11, 2022
- Median duration of exposure: TAGRISSO® 35.8 months (range 0 to 38), placebo 25.1 months (range 0 to 39)
- None of the adverse events that occurred in at least 10% of patients were grade 4 or higher
- Adverse events that led to a dose reduction: TAGRISSO® n = 42 (12%); control arm n = 3 (1%)
- Adverse events that led to treatment interruption: TAGRISSO® n = 91 (27%); control arm n = 43 (13%)
- Adverse events that led to treatment discontinuation: TAGRISSO® n = 43 (13%); control arm n = 9 (3%)
- Treatment related adverse events that led to death: TAGRISSO® n = 0; control arm n = 0
