Enhertu granted Priority Review in the US for the treatment of HER2-positive metastatic gastric cancer

Enhertu granted Priority Review in the US for the
treatment of HER2-positive metastatic gastric cancer
 
Only HER2-directed medicine to demonstrate significant improvement in overall survival compared to chemotherapy for previously treated patients in this setting
 
AstraZeneca and Daiichi Sankyo Company, Limited (Daiichi Sankyo)'s Enhertu (trastuzumab deruxtecan) has received acceptance for its supplemental Biologics License Application (sBLA) and has also been granted Priority Review in the US for the treatment of patients with HER2-positive metastatic gastric or gastroesophageal junction (GEJ) adenocarcinoma.
 
The Food and Drug Administration (FDA) grants Priority Review to applications for medicines that offer significant advances over available options by demonstrating safety or efficacy improvements, preventing serious conditions, or enhancing patient compliance. The Prescription Drug User Fee Act date, the FDA action date for their regulatory decision, will be during the first quarter of 2021.
 
There are more than 27,000 new cases of gastric cancer in the US each year, of which approximately one in five are HER2 positive.1,2 For patients with metastatic gastric cancer who progress on initial treatment with an anti-HER2 medicine, there are no other approved HER2-directed medicines.
 
José Baselga, Executive Vice President, Oncology R&D, said: "Once patients with HER2-positive metastatic gastric cancer progress following initial treatment with an anti-HER2 regimen, there are no approved HER2-directed medicines. The prognosis for these patients is poor, as available treatment options offer only limited clinical benefit. This milestone brings us one step closer to delivering a potentially practice-changing medicine to patients with gastric cancer in the US."
 
Antoine Yver, Executive Vice President and Global Head, Oncology Research and Development, Daiichi Sankyo, said: "The results of the DESTINY-Gastric01 trial are unprecedented as they represent the first time a HER2-directed medicine has demonstrated an improvement in survival following chemotherapy and HER2 treatment in the metastatic setting. Building on the recent Breakthrough Therapy Designation, the filing of the application and Priority Review by the FDA for this potential new indication for Enhertu reflects the importance of the data and the significant unmet need for patients with previously treated HER2-positive metastatic gastric cancer."
 
The sBLA was based on results from the DESTINY-Gastric01 randomised Phase II trial, which demonstrated a statistically significant and clinically meaningful improvement in objective response rate (ORR), the primary endpoint, and overall survival (OS), a key secondary endpoint, for patients treated with Enhertu versus chemotherapy (paclitaxel or irinotecan monotherapy).
 
The safety and tolerability profiles of Enhertu in DESTINY-Gastric01 were consistent with that observed in the gastric cancer cohort of the Phase I trial and previously reported Enhertu trials in other tumours.3 The most common Grade 3 or higher treatment-emergent adverse events were decreased neutrophil count, anaemia, decreased white blood cell count and decreased appetite. There were 12 (9.6%) cases of confirmed treatment-related interstitial lung disease (ILD) or pneumonitis in 125 patients treated with Enhertu as determined by an independent review committee. The majority of cases were Grade 1 or 2 with two Grade 3, one Grade 4 and no Grade 5 (ILD-related deaths).
 
The results from the trial were presented during the American Society of Clinical Oncology ASCO20 Virtual Scientific Program and simultaneously published online in The New England Journal of Medicine in May 2020.4
 
Enhertu received Breakthrough Therapy Designation from the FDA in May 2020 for patients with unresectable or metastatic HER2-positive gastric or GEJ adenocarcinoma who have received two or more prior regimens including trastuzumab and Orphan Drug Designation for patients with gastric cancer, including GEJ adenocarcinoma. Enhertu has not been approved in the US for gastric or GEJ adenocarcinoma.
 
Gastric cancer
Gastric (stomach) cancer is the fifth most common cancer worldwide and the third leading cause of cancer mortality with a five-year survival rate of 5% for metastatic disease; there were approximately one million new cases reported in 2018 and 783,000 deaths.5,6 In the US, it is estimated that 27,600 new cases of gastric cancer will be diagnosed in 2020 and more than 11,000 people will die from the disease.1
 
Approximately one in five gastric cancers are HER2 positive.2 HER2 is a tyrosine kinase receptor growth-promoting protein expressed on the surface of many types of tumours including breast, gastric, lung and colorectal cancers. Gastric cancer is usually diagnosed in the advanced stage, but even when diagnosed in earlier stages of the disease, the survival rate remains modest.7 Recommended 1st-line treatment for HER2-positive advanced or metastatic gastric cancer is combination chemotherapy plus trastuzumab, an anti-HER2 medicine, which has been shown to improve survival outcomes when added to chemotherapy. For metastatic gastric cancer that progresses on 1st-line treatment, there are no other approved HER2-targeted medicines.8
 
DESTINY-Gastric01
DESTINY-Gastric01 is a Phase II, open-label, multi-centre, randomised controlled trial testing the safety and efficacy of Enhertu versus investigator's choice of chemotherapy in a primary cohort of 188 patients from Japan and South Korea with HER2-positive (defined as IHC3+ or IHC2+/ISH+), advanced gastric or GEJ adenocarcinoma who have progressed on two or more prior treatment regimens including fluoropyrimidine and platinum chemotherapy and trastuzumab. Patients were randomised 2:1 to receive Enhertu or investigator's choice of chemotherapy (paclitaxel or irinotecan monotherapy). Patients were treated with Enhertu 6.4mg/kg once every three weeks or chemotherapy.
 
The primary endpoint of the trial is ORR, as assessed by independent central review. OS, a key secondary endpoint, was to be evaluated hierarchically at a prespecified interim analysis if the primary endpoint was statistically significant. Additional efficacy endpoints include progression-free survival, duration of response, disease control rate and confirmed ORR assessed in those responses confirmed by a follow-up scan of at least four weeks after initial independent central review.9
 
Enhertu
Enhertu (trastuzumab deruxtecan; fam-trastuzumab deruxtecan-nxki in the US) is a HER2-directed antibody drug conjugate (ADC) and is the lead ADC in the oncology portfolio of Daiichi Sankyo and the most advanced programme in AstraZeneca's ADC scientific platform. ADCs are targeted cancer medicines that deliver cytotoxic chemotherapy ('payload') to cancer cells via a linker attached to a monoclonal antibody that binds to a specific target expressed on cancer cells. Enhertu is comprised of a HER2 monoclonal antibody attached to a topoisomerase I inhibitor payload by a tetrapeptide-based linker.
 
Enhertu (5.4mg/kg) is approved in the US and Japan for the treatment of adult patients with unresectable or metastatic HER2-positive breast cancer who have received two or more prior anti-HER2-based regimens in the metastatic setting based on the DESTINY-Breast01 trial, and is under accelerated assessment in the EU for HER2-positive metastatic breast cancer. In September 2020, Enhertu (6.4mg/kg) was approved in Japan for patients with HER2-positive unresectable advanced or recurrent gastric cancer that progressed after chemotherapy.
