Hansoh Pharma's Ameile (Almonertinib) Receives Marketing Authorization in China for Second-Line Treatment for Patients With EGFR T790M-Mutation Non-Small Cell Lung Cancer

SHANGHAI, March 19, 2020 /PRNewswire/ -- Hansoh Pharmaceutical Group Company Limited ("Hansoh Pharma"), a leading biopharmaceutical company in China, announced that the National Medical Products Administration (NMPA) has granted marketing authorization for AMEILE (almonertinib, previously also known as HS-10296) once daily tablets for the treatment of patients with metastatic epidermal growth factor receptor (EGFR) T790M mutation-positive non-small cell lung cancer (NSCLC), who have progressed on or after other EGFR tyrosine kinase inhibitor (TKI) therapy.

AMEILE is the second 3^rd generation EGFR TKI to be approved for metastatic NSCLC patients with EGFR T790M. The approval of AMEILE provides a highly efficacious treatment option with favorable safety profile for advanced NSCLC patients.

Lung cancer remains the leading cause of cancer-related deaths worldwide and in China. EGFR mutation is the most common mutation and accounts for about 40% of NSCLC patients in China. Approximately 50% of NSCLC patients will develop drug-resistant T790M mutation following treatment with first or second generation EGFR TKI. In its registrational study, APOLLO (n=244), patients taking AMEILE has shown a median progression-free-survival (mPFS) of greater than a year, the longest in its class as a monotherapy in second line therapy. AMEILE provides a new option with favorable safety profile and high efficacy for NSCLC patients in China, and is another illustration of Hansoh Pharma's steadfast commitment in developing life-changing medicines to help patients and families in need around the world.

The NMPA's approval of AMEILE was supported by clinical results from APOLLO study, a multicenter, open-label, single-arm Phase 2 study conducted in patients with recurrent NSCLC harboring EGFR T790M mutations. In this study, a total of 244 patients were treated with 110mg of almonertinib. The primary endpoint was objective response rate (ORR) as determined by blinded independent central review (ICR). Key secondary endpoints include PFS assessed by ICR, disease control rate (DCR), duration of response (DoR), and overall survival (OS). In APOLLO trial, ORR was 68.9%, DCR was 93.4%, mPFS was 12.3 months, and ORR in patients with CNS metastasis was 61.5%.^[1,2] Further, almonertinib was well tolerated, where most common AEs were grade 1 or 2, with less than three percent patients discontinued treatment with almonertinib due to drug-related AEs. There was no interstitial lung disease reported during this study while neither grade 3 rash nor QT prolongation was observed. The most commonly observed adverse events, regardless of attribution, were blood creatine phosphokinase increased, rash, pruritus, aspartate aminotransferase increased, and alanine aminotransferase increased. ^[1,2]
