Dacomitinib (Vizimpro) is accepted for use within NHSScotland...as monotherapy, 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.

Vizimpro, as monotherapy, is indicated 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.

First-line treatment of EGFR-mutated NSCLC: Patients with a tumour with a sensitising EGFR mutation should receive first-line EGFR TKIs including erlotinib, gefitinib or afatinib [I, A], or dacomitinib.

…the NCCN NSCLC Panel preference stratified first-line therapy for patients with EGFR mutation positive metastatic NSCLC. Erlotinib, gefitinib, afatinib, or dacominitib are "other recommended " EGFR TKI options for first-line therapy.

Dacomitinib showed promising efficacy and manageable safety profile for advanced NSCLC with brain metastasis harboring EGFR mutation in the first-line treatment.

This is a multi-center retrospective study of advanced non-small cell patients with EGFR mutations who received dacomitinib treatment from January 2019 to 2021.All patients received a 30 mg oral dose of dacomitinib….The control rate (DCR) was 100%, and PFS and OS were not reached in 30 patients....As a first-line treatment, 30 mg dacomitinib has a good curative effect on patients with classic EGFR mutations and has fewer adverse reactions of grade 3 or higher.

Dacomitinib demonstrated favorable activity with manageable toxicity in patients with NSCLC harboring major uncommon EGFR mutations.

In the whole cohort, 55.3 % of patients (21/38) had a confirmed partial response and 89.5 % (34/38) had disease control, and the median PFS was 10.3 months (95 % confidence interval [CI], 5.8–14.8)....This real-world study indicates that dacomitinib is potent and well-tolerated in NSCLC patients harboring uncommon EGFR mutations in multi-line settings, and has favourable activity for brain metastases.

Ninety-nine patients with advanced NSCLC who received dacomitinib (30mg daily or 45 mg daily) after initial diagnosis or 1-4 cycle of chemotherapy treatment were included in this ambispective (both retrospective and prospective) multicentric study. Treatment outcomes of these patients were analyzed....Dacomitinib showed significantly active in EGFR TKI-naïve patients with advance EGFR-positive NSCLC, and was well tolerated.

The hazard ratio (HR) for OS was 0.748 (95% CI 0.591-0.947; two-sided P = 0.0155); median OS was 34.1 months with dacomitinib versus 27.0 months with gefitinib. The HR for OS in patients with dose reduction(s) in the dacomitinib arm (n = 154) compared with all patients in the gefitinib arm was 0.554 (95% CI 0.420-0.730); median OS was 42.5 months for patients with dose reduction(s) in the dacomitinib arm.

Among subgroups, dacomitinib showed a numerical improvement of OS compared with all other EGFR TKIs among patients with exon 21 L858R substitution mutation and among Asian patients while osimertinib showed a numerical improvement of OS compared with all other EGFR TKIs among patients with exon 19 deletion mutation and among non-Asian patients.

Patients with NSCLC, Eastern Cooperative Oncology Group performance status 0 to 2, no prior HER-directed therapy, and one/two prior chemotherapy regimens received dacomitinib 45 mg or erlotinib 150 mg once daily….For the EGFR mutant subset, median PFS was 7.44 months for both dacomitinib and erlotinib...
