WILMINGTON, Del.

AstraZeneca’s TAGRISSO® (osimertinib) has been approved in the US for the adjuvant treatment of adult patients with early-stage epidermal growth factor receptor-mutated (EGFRm) non-small cell lung cancer (NSCLC) after tumor resection with curative intent. TAGRISSO is indicated for EGFRm patients whose tumors have exon 19 deletions or exon 21 L858R mutations as detected by an approved test.

The approval was granted under the US Food and Drug Administration’s (FDA) Real-Time Oncology Review (RTOR) pilot program. Five other countries participated in a concurrent submission and review process through FDA’s Project Orbis.

While up to 30% of all patients with NSCLC may be diagnosed early enough to have potentially curative surgery, disease recurrence is still common in early-stage disease and nearly half of patients diagnosed in Stage IB, and over three quarters of patients diagnosed in Stage IIIA, experience recurrence within five years.1-4

The approval was based on results from the ADAURA Phase III trial where TAGRISSO demonstrated a statistically significant and clinically meaningful improvement in disease-free survival (DFS) in the primary analysis population of patients with Stage II and IIIA EGFRm NSCLC, and also in the overall trial population of patients with Stage IB-IIIA disease, a key secondary endpoint.

Roy S. Herbst, MD, PhD, chief of Medical Oncology at Yale Cancer Center and Smilow Cancer Hospital, New Haven, CT and principal investigator in the ADAURA Phase III trial, said: “Adjuvant TAGRISSO has demonstrated an unprecedented disease-free survival benefit for early-stage lung cancer patients with EGFR mutations who face high rates of recurrence even after successful surgery and subsequent chemotherapy. This approval reinforces how critical it is to test all lung cancer patients for EGFR mutations before deciding how to treat them and regardless of their stage at diagnosis. This will help ensure as many patients as possible can benefit from this potentially practice-changing treatment.”

Dave Fredrickson, Executive Vice President, Oncology Business Unit, said: “For the first time, a targeted, biomarker-driven treatment option is available to patients in the US with early-stage EGFR-mutated lung cancer. This approval dispels the notion that treatment is over after surgery and chemotherapy, as the ADAURA results show that TAGRISSO can dramatically change the course of this disease. We remain committed to treating cancer patients earlier, when they may still have a chance of being cured.”

Adjuvant treatment with TAGRISSO reduced the risk of disease recurrence or death by 83% in the primary endpoint of DFS in patients with Stage II and IIIA disease (hazard ratio [HR] 0.17; 95% confidence interval [CI] 0.12-0.23; p<0.0001). DFS results in the overall trial population of patients with Stage IB-IIIA disease showed TAGRISSO reduced the risk of disease recurrence or death by 80% (HR 0.20; 95% CI 0.15-0.27; p<0.0001). At two years, 89% of patients treated with TAGRISSO remained alive and disease free versus 52% on placebo after surgery, the current standard of care. The safety and tolerability of TAGRISSO in this trial was consistent with previous trials in the metastatic setting.

TAGRISSO was recently granted Breakthrough Therapy Designation for patients in the early-stage disease setting by the US FDA. In April 2020, an Independent Data Monitoring Committee recommended for the ADAURA trial to be unblinded two years early based on a determination of overwhelming efficacy. Investigators and patients continue to participate in the trial and remain blinded to treatment. The results from the ADAURA trial were presented during the plenary session of the American Society of Clinical Oncology ASCO20 Virtual Scientific Program in May 2020 and were recently published in The New England Journal of Medicine.

The US regulatory submission was reviewed under the FDA’s RTOR pilot program which aims to ensure that safe and effective treatments are available to patients as early as possible. Five national health authorities collaborated with the FDA on this review through Project Orbis, an initiative of the FDA Oncology Center of Excellence, which provides a framework for concurrent submission and review of oncology medicines among international partners. These included Health Canada, the Australian Therapeutic Goods Administration, the Brazilian Health Regulatory Agency (Anvisa), Swissmedic, and Singapore Health Sciences Authority. The UK Medicines and Healthcare products Regulatory Agency participated in the review as an observer.

In China, TAGRISSO is under priority review for the adjuvant treatment of patients with early-stage EGFRm NSCLC based on the ADAURA Phase III trial. This indication is also under regulatory review in the EU and additional global submission discussions are ongoing.

TAGRISSO is a once-daily oral tablet approved for the 1st-line treatment of patients with metastatic EGFRm NSCLC and for the treatment of metastatic EGFR T790M mutation-positive NSCLC in the US, Japan, China, the EU and many other countries around the world.

TAGRISSO Important Safety Information

  • There are no contraindications for TAGRISSO
  • Interstitial lung disease (ILD)/pneumonitis occurred in 3.7% of the 1479 TAGRISSO-treated patients; 0.3% 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 is confirmed
  • Heart rate-corrected QT (QTc) interval prolongation occurred in TAGRISSO-treated patients. Of the 1479 TAGRISSO-treated patients in clinical trials, 0.8% were found to have a QTc >500 msec, and 3.1% 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% of the 1479 TAGRISSO-treated patients; 0.1% of cardiomyopathy cases were fatal. A decline in left ventricular ejection fraction (LVEF) ≥10% from baseline and to <50% LVEF occurred in 3.2% of 1233 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%. Conduct cardiac monitoring, including assessment of LVEF at baseline and during treatment, in patients with cardiac risk factors. 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 0.7% of 1479 patients treated with TAGRISSO 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 Stevens-Johnson syndrome (SJS) and erythema multiforme major (EMM) have been reported in patients receiving TAGRISSO. Withhold TAGRISSO if SJS or EMM 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
  • 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
  • Most common (≥20%) adverse reactions, including laboratory abnormalities, were leukopenia, lymphopenia, thrombocytopenia, diarrhea, anemia, rash, musculoskeletal pain, nail toxicity, neutropenia, dry skin, stomatitis, fatigue, and cough

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.5 Lung cancer is broadly split into NSCLC and small cell lung cancer, with 80-85% classified as NSCLC.6 The majority of all NSCLC patients are diagnosed with advanced disease while approximately 25-30% present with resectable disease at diagnosis.1-3

For those with resectable tumors, the majority of patients eventually develop recurrence despite complete tumor resection and adjuvant chemotherapy.4 Early-stage lung cancer diagnoses are often only made when the cancer is found on imaging for an unrelated condition.7,8

Approximately 10-15% of NSCLC patients in the US and Europe, and 30-40% of patients in Asia have EGFRm NSCLC.9-11 These patients are particularly sensitive to treatment with EGFR-tyrosine kinase inhibitors (TKIs) which block the cell-signaling pathways that drive the growth of tumor cells.12

About ADAURA

ADAURA is a randomized, double-blinded, global, placebo-controlled Phase III trial in the adjuvant treatment of 682 patients with Stage IB, II, IIIA EGFRm NSCLC following complete tumor resection and adjuvant chemotherapy as indicated. Patients were treated with TAGRISSO 80 mg once-daily oral tablets or placebo for three years or until disease recurrence.

The trial enrolled in more than 200 centers across more than 20 countries, including the US, in Europe, South America, Asia and the Middle East. The primary endpoint was DFS in Stage II and IIIA patients and a key secondary endpoint was DFS in Stage IB, II and IIIA patients. The data readout was originally anticipated in 2022. The trial will continue to assess overall survival.
