Pfizer receives positive CHMP opinion for Vizimpro® (dacomitinib) for the first-line treatment of adult patients with locally advanced or metastatic non-small cell lung cancer with EGFR-activating mutations

PfizerPfizer today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion recommending Vizimpro® (dacomitinib) 45 mg, as monotherapy, be granted marketing authorization in the European Union (EU) for the first-line treatment of adult patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR)-activating mutations. The CHMP's opinion will now be reviewed by the European Commission (EC).

Vizimprowas approved by the U.S. Food and Drug Administration (FDA) in 2018 for the first-line treatment of patients with metastatic NSCLC with EGFR exon 19 deletion or exon 21 L858R substitution mutations as detected by an FDA-approved test. It was also recently approved in Japan for EGFR gene mutation-positive, inoperable or recurrent NSCLC.

"Patients with EGFR-mutated non-small cell lung cancer, a disease that is associated with low overall survival rates, are in need of more treatment options. This positive CHMP opinion is an important step toward bringing this treatment to patients in Europe as a potential new first-line treatment option," said Chris Boshoff, M.D., Ph.D., Chief Development Officer, Oncology, Pfizer Global Product Development. "Vizimpro's development is a direct result of Pfizer's focus on precision drug development to create tailored options that improve patient outcomes."

The Marketing Authorization Application (MAA) for Vizimpro was based on results from ARCHER 1050, a randomized, multicenter, multinational, open-label, Phase 3 study conducted in patients with locally advanced unresectable, or metastatic NSCLC harboring EGFR exon 19 deletion or exon 21 L858R substitution mutations, an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1; with no prior therapy for metastatic disease or recurrent disease with a minimum of 12 months disease-free after completion of systemic therapy. A total of 452 patients were randomized 1:1 to Vizimpro 45 mg (n=227) or gefitinib 250 mg (n=225).

About Vizimpro® (dacomitinib)

Vizimpro is an oral, once-daily, irreversible pan-human epidermal growth factor receptor kinase inhibitor for first-line treatment of adult patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR)-activating mutations.

Vizimpro is approved in the U.S. for the first-line treatment of patients with metastatic non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) exon 19 deletion or exon 21 L858R substitution mutations as detected by an FDA-approved test. Vizimpro is also approved in Japan for EGFR gene mutation-positive, inoperable or recurrent NSCLC. The applications in the US and Japan were reviewed and approved under the Priority Review program.

In 2012, Pfizer and SFJ Pharmaceuticals entered into a collaborative development agreement to conduct ARCHER 1050 across multiple sites. SFJ is a global drug development company, which provides a unique and highly customized co-development partnering model for the world’s top pharmaceutical and biotechnology companies. Under the terms of this agreement, SFJ Pharmaceuticals provided the funding and conducted the trial to generate the clinical data used to support this application. Pfizer retains all rights to commercialize Vizimpro globally.

About ARCHER 1050

The efficacy of Vizimpro was demonstrated in ARCHER 1050, a global Phase 3 head-to-head trial conducted in patients with locally advanced unresectable, or metastatic non-small cell lung cancer (NSCLC) harboring epidermal growth factor receptor (EGFR) exon 19 deletion or exon 21 L858R substitution mutations, with no prior therapy for metastatic disease or recurrent disease with a minimum of 12 months disease-free after completion of systemic therapy. A total of 452 patients were randomized 1:1 to Vizimpro 45 mg (n=227) or gefitinib 250 mg (n=225). Randomization was stratified by region and EGFR mutation status. The primary endpoint of the study was progression-free survival (PFS) as determined by blinded Independent Radiology Central (IRC) review. Key secondary endpoints included objective response rate (ORR), duration of response (DoR), overall survival (OS), and patient-reported outcomes (PROs).

About Non-Small Cell Lung Cancer

Lung cancer is the most common cancer worldwide, with more than two million new cases diagnosed globally in 2018.(1) About 85 percent of all lung cancers are identified as non-small cell, and approximately 75 percent of these are metastatic, or advanced, at diagnosis.(2)

EGFR is a protein that helps cells grow and divide. When the EGFR gene is mutated it can cause the protein to be overactive resulting in cancer cells to form. EGFR mutations may occur in 10 to 35 percent of NSCLC tumors globally, and most common activating mutations are deletions in exon 19 and exon 21 L858R substitution, which together account for more than 80 percent of known activating EGFR mutations. The disease is associated with low survival rates and disease progression remains a challenge.(1,2)
