First and only EGFR inhibitor and
targeted treatment to show benefit in Stage III setting, extending
progression-free survival by more than three years
Positive results from the LAURA Phase III trial showed
AstraZeneca’s TAGRISSO® (osimertinib) demonstrated a statistically
significant and highly clinically meaningful improvement in
progression-free survival (PFS) for patients with unresectable,
Stage III epidermal growth factor receptor-mutated (EGFRm)
non-small cell lung cancer (NSCLC) whose tumors have exon 19
deletions or exon 21 (L858R) mutations, after chemoradiotherapy
(CRT) compared to placebo after CRT.
These results will be presented today during the Plenary Session
at the 2024 American Society of Clinical Oncology (ASCO) Annual
Meeting (abstract #LBA4) and simultaneously published in The New
England Journal of Medicine.
Results showed TAGRISSO reduced the risk of disease progression
or death by 84% compared to placebo (hazard ratio [HR] 0.16; 95%
confidence interval [CI] 0.10-0.24; p<0.001) as assessed by
blinded independent central review (BICR). Median PFS was 39.1
months in patients treated with TAGRISSO versus 5.6 months for
placebo. Importantly, a clinically meaningful PFS benefit was
observed across all prespecified subgroups including sex, race,
type of EGFR mutation, age, smoking history, and prior CRT.
Overall survival (OS) data showed a favorable trend for
TAGRISSO, although data were not mature at the time of this
analysis. The trial will continue to assess OS as a secondary
endpoint.
Suresh Ramalingam, MD, Executive Director of Winship Cancer
Institute of Emory University, Atlanta, US and principal
investigator in the trial, said: “The impressive progression-free
survival results from the LAURA Phase III trial represent a major
breakthrough for patients with Stage III EGFR-mutated lung cancer
for whom no targeted treatments are available. Osimertinib delayed
the risk of disease progression or death by an unprecedented 84%
and should become the new standard of care for patients in this
setting based on these data.”
Susan Galbraith, Executive Vice President, Oncology R&D,
AstraZeneca, said: “TAGRISSO extended progression-free survival by
more than three years in this potentially curative setting,
reinforcing the need to test and diagnose patients early. These
practice-changing data cement the powerful impact TAGRISSO can make
as backbone therapy in EGFR-mutated lung cancer, especially in the
lives of these patients who have historically experienced early
progression following chemoradiotherapy.”

Safety results and discontinuation rates due to adverse events
(AEs) were as expected and no new safety concerns were identified.
Grade 3 or higher AEs from all causes occurred in 35% of patients
in the TAGRISSO arm versus 12% in the placebo arm.
TAGRISSO is approved as monotherapy in more than 100 countries
including in the US, EU, China and Japan. Approved indications
include for 1st-line treatment of patients with locally advanced or
metastatic EGFRm NSCLC, locally advanced or metastatic EGFR T790M
mutation-positive NSCLC, and adjuvant treatment of early-stage
EGFRm NSCLC. TAGRISSO with the addition of chemotherapy is also
approved in the US and several other countries for 1st-line
treatment of patients with locally advanced or metastatic EGFRm
NSCLC.
IMPORTANT SAFETY INFORMATION
- There are no contraindications for TAGRISSO
- Interstitial lung disease (ILD)/pneumonitis occurred in 4% of
the 1813 TAGRISSO-treated patients; 0.4% of cases were fatal. In
the FLAURA2 study, ILD/pneumonitis occurred in 3.3% of the 276
patients who received TAGRISSO in combination with pemetrexed and
platinum-based chemotherapy; 0.4% of cases were fatal. Withhold
TAGRISSO and promptly investigate for ILD in patients who present
with worsening of respiratory symptoms which may be indicative of
ILD (eg, dyspnea, cough and fever). Permanently discontinue
TAGRISSO if ILD/pneumonitis is confirmed
- Heart rate-corrected QT (QTc) interval prolongation occurs in
TAGRISSO-treated patients. Of the 1813 TAGRISSO monotherapy-treated
patients in clinical trials, 1.1% were found to have a QTc >500
msec, and 4.3% of patients had an increase from baseline QTc >60
msec. Of the 276 patients treated with TAGRISSO in combination with
pemetrexed and platinum-based chemotherapy in the FLAURA2 study,
1.8% were found to have a QTc >500 msec, and 10.5% of patients
had an increase from baseline QTc >60 msec. No QTc-related
arrhythmias were reported. Conduct periodic monitoring with ECGs
and electrolytes in patients with congenital long QTc syndrome,
congestive heart failure, electrolyte abnormalities, or those who
are taking medications known to prolong the QTc interval.
Permanently discontinue TAGRISSO in patients who develop QTc
interval prolongation with signs/symptoms of life-threatening
arrhythmia
- Cardiomyopathy occurred in 3.8% of the 1813 TAGRISSO-treated
patients; 0.1% of cardiomyopathy cases were fatal. In the FLAURA2
study, cardiomyopathy occurred in 9% of the 276 patients who
received TAGRISSO in combination with pemetrexed and platinum-based
chemotherapy; 1.1% of cardiomyopathy cases were fatal. A decline in
left ventricular ejection fraction (LVEF) ≥10% from baseline and to
<50% LVEF occurred in 4.2% of 1557 patients who had baseline and
at least one follow-up LVEF assessment. In the ADAURA study, 1.5%
(5/325) of TAGRISSO-treated patients experienced LVEF decreases
≥10% from baseline and a drop to <50%. In the FLAURA2 study, 8%
(21/262) of patients treated with TAGRISSO in combination with
pemetrexed and platinum-based chemotherapy, who had baseline and at
least one follow-up LVEF assessment, experienced LVEF decreases
≥10% and a drop to less than 50%. For patients receiving TAGRISSO
monotherapy, conduct cardiac monitoring in patients with cardiac
risk factors, including assessment of LVEF at baseline and during
treatment. For patients receiving TAGRISSO in combination with
pemetrexed and platinum-based chemotherapy, conduct cardiac
monitoring in all patients, including assessment of LVEF at
baseline and during treatment. Assess LVEF in patients who develop
relevant cardiac signs or symptoms during treatment. For
symptomatic congestive heart failure, permanently discontinue
TAGRISSO
- Keratitis was reported in 0.6% of 1813 patients treated with
TAGRISSO monotherapy in clinical trials. Promptly refer patients
with signs and symptoms suggestive of keratitis (such as eye
inflammation, lacrimation, light sensitivity, blurred vision, eye
pain and/or red eye) to an ophthalmologist
- Postmarketing cases consistent with erythema multiforme major
(EMM), Stevens-Johnson syndrome (SJS) and toxic epidermal
necrolysis (TEN) have been reported in patients receiving TAGRISSO.
Withhold TAGRISSO if EMM, SJS, or TEN is suspected and permanently
discontinue if confirmed
- Postmarketing cases of cutaneous vasculitis including
leukocytoclastic vasculitis, urticarial vasculitis, and IgA
vasculitis have been reported in patients receiving TAGRISSO.
Withhold TAGRISSO if cutaneous vasculitis is suspected, evaluate
for systemic involvement, and consider dermatology consultation. If
no other etiology can be identified, consider permanent
discontinuation of TAGRISSO based on severity
- Aplastic anemia has been reported in patients treated with
TAGRISSO in clinical trials (0.06% of 1813) and postmarketing. Some
cases had a fatal outcome. Inform patients of the signs and
symptoms of aplastic anemia including but not limited to, new or
persistent fevers, bruising, bleeding, and pallor. If aplastic
anemia is suspected, withhold TAGRISSO and obtain a hematology
consultation. If aplastic anemia is confirmed, permanently
discontinue TAGRISSO. Perform complete blood count with
differential before starting TAGRISSO, periodically throughout
treatment, and more frequently if indicated
- Verify pregnancy status of females of reproductive potential
prior to initiating TAGRISSO. Advise pregnant women of the
potential risk to a fetus. Advise females of reproductive potential
to use effective contraception during treatment with TAGRISSO and
for 6 weeks after the final dose. Advise males with female partners
of reproductive potential to use effective contraception for 4
months after the final dose
- Because of the potential for serious adverse reactions in
breastfed infants from TAGRISSO, women should not breastfeed during
treatment with TAGRISSO and for 2 weeks after the final dose
- Most common (≥20%) adverse reactions, including laboratory
abnormalities, were:
- TAGRISSO monotherapy: leukopenia, lymphopenia,
thrombocytopenia, anemia, diarrhea, rash, musculoskeletal pain,
neutropenia, nail toxicity, dry skin, stomatitis, and fatigue
- TAGRISSO in combination with pemetrexed and platinum-based
chemotherapy: leukopenia, thrombocytopenia, neutropenia,
lymphopenia, rash, diarrhea, stomatitis, nail toxicity, dry skin,
and increased blood creatinine

Notes
Lung cancer
Lung cancer is the leading cause of cancer death among both men
and women, accounting for about one-fifth of all cancer deaths.1
Lung cancer is broadly split into NSCLC and small cell lung
cancer.2 Each year there are an estimated 2.4 million people
diagnosed with lung cancer globally, with 80-85% of patients
diagnosed with NSCLC, the most common form of lung cancer. The
majority of all NSCLC patients are diagnosed with advanced
disease.1-4
Approximately 10-15% of NSCLC patients in the US and Europe, and
30-40% of patients in Asia have EGFRm NSCLC.5-7 Patients with EGFRm
NSCLC are particularly sensitive to treatment with an EGFR-tyrosine
kinase inhibitor (EGFR-TKI) which blocks the cell-signaling
pathways that drive the growth of tumor cells.8
LAURA
LAURA is a randomized, double-blind, placebo-controlled,
multi-center, global Phase III trial in patients with unresectable,
Stage III EGFRm NSCLC whose disease has not progressed following
definitive platinum‑based CRT. Patients were treated with TAGRISSO
80mg once daily oral tablets until disease progression,
unacceptable toxicity or other discontinuation criteria were met.
Upon progression, patients in the placebo arm were permitted to be
treated with TAGRISSO.
The trial enrolled 216 patients in more than 145 centers across
more than 15 countries, including in the US, Europe, South America
and Asia. This is the analysis of the primary endpoint of PFS. The
trial is ongoing and will continue to assess the secondary endpoint
of OS.
TAGRISSO
TAGRISSO® (osimertinib) is a third-generation, irreversible
EGFR-TKI with proven clinical activity in NSCLC, including against
central nervous system (CNS) metastases. TAGRISSO (40 mg and 80 mg
once-daily oral tablets) has been used to treat nearly 800,000
patients across its indications worldwide and AstraZeneca continues
to explore TAGRISSO as a treatment for patients across multiple
stages of EGFRm NSCLC.
There is an extensive body of evidence supporting the use of
TAGRISSO in EGFRm NSCLC. TAGRISSO is the only targeted therapy to
improve patient outcomes in early-stage disease in the ADAURA Phase
III trial, locally advanced stages in the LAURA Phase III trial and
late-stage disease in the FLAURA Phase III trial and FLAURA2 Phase
III trial.
As part of AstraZeneca’s ongoing commitment to treating patients
as early as possible in lung cancer, TAGRISSO is also being
investigated in the neoadjuvant setting in the NeoADAURA Phase III
trial with results expected later this year and in the early-stage
adjuvant resectable setting in the ADAURA2 Phase III trial.
The Company is also researching ways to address tumor mechanisms
of resistance through the SAVANNAH and ORCHARD Phase II trials, and
the SAFFRON Phase III trial, which test TAGRISSO plus savolitinib,
an oral, potent and highly selective MET TKI, as well as other
potential new medicines.
