15 of 17 EGFR-mutant patients received EGFR-TKI therapy with gefitinib (n = 13) or osimertinib (n = 2). The OS tended to be longer in the TKI group than in the CT or BSC group (16.9 months vs. 7.2 months or 9.8 months, p = 0.059). Among the 34 super-elderly NSCLC patients with a PS score of 3-4, 7 with EGFR-mutant received gefitinib therapy and the remaining 27 received BSC alone. The OS tended to be longer in the TKI group than in the BSC group (4.6 months vs. 2.3 months, p = 0.060).

Title:
A meta-analysis of the safety and effectiveness of pemetrexed compared with gefitinib for pre-treated advanced or metastatic NSCLC
Published date:
07/17/2020
Excerpt:
Pemetrexed was not associated with survival benefit than gefitinib therapy among pre-treated NSCLC patients. While, gefitinib showed superior PFS efficacy than pemetrexed for patients with EGFR mutation-type.

Impact of Epidermal Growth Factor Receptor and KRAS Mutations on Clinical Outcomes in Previously Untreated Non–Small Cell Lung Cancer Patients: Results of an Online Tumor Registry of Clinical Trials
Excerpt:
Of the 84 patients harboring a sensitizing EGFR mutation who were treated with either erlotinib or gefitinib, 56 patients (67%) achieved an objective response (1 complete response, 55 partial response).

Title:
Continued gefitinib retreatment beyond progression in patients with advanced non-small cell lung cancer harboring sensitive EGFR mutations
Excerpt:
Patients with sensitive EGFR mutations received first-line treatment with gefitinib followed by retreatment with gefitinib after disease progression….The median PFS-1 and PFS-2 were 10.0 months and 14.0 months, respectively. The median overall survival (OS) was 36.0 months.

Epidermal growth factor receptor mutations in needle biopsy/aspiration samples predict response to gefitinib therapy and survival of patients with advanced nonsmall cell lung cancer
Excerpt:
EGFR mutation was assessed from DNA of 63 paraffin-embedded small needle biopsy/aspiration specimens from 62 patients with NSCLC treated with gefitinib….Patients with EGFR mutations had a significantly better response rate compared to that of the nonmutation group (p < 0.001).

Gefitinib Alone Versus Gefitinib Plus Chemotherapy for Non-Small-Cell Lung Cancer With Mutated Epidermal Growth Factor Receptor: NEJ009 Study
Excerpt:
Compared with gefitinib alone, gefitinib combined with carboplatin plus pemetrexed improved PFS in patients with untreated advanced NSCLC with EGFR mutations with an acceptable toxicity profile, although its OS benefit requires further validation.
Secondary therapy:
carboplatin + pemetrexed

Title:
A Randomized Phase 2 Study of Gefitinib With or Without Pemetrexed as First-line Treatment in Nonsquamous NSCLC With EGFR Mutation: Final Overall Survival and Biomarker Analysis
Excerpt:
This was a phase 2, multicenter, randomized study conducted in East Asian patients with advanced nonsquamous NSCLC with EGFR mutations. Patients were randomized (2:1) to receive P+G (500 mg/m2 intravenously 3-weekly + 250 mg/day orally) or gefitinib...Median OS was 43.4 months in P+G versus 36.8 months in gefitinib arm; adjusted HR 0.77 (95% CI, 0.5-1.2); one-sided P=0.105. Median PFS was significantly longer in the P+G (16.2 months) versus gefitinib arm (11.1 months); adjusted HR 0.67 (95% CI, 0.5-0.9); one-sided P=0.009. In the P+G and gefitinib arms, median PFS was 22.6 and 11.0 months, respectively, in patients with low thymidylate synthase (TS) expression, and 12.6 and 9.9 months, respectively, in patients with high TS expression.

Title:
Insight into binding mechanisms of EGFR allosteric inhibitors using molecular dynamics simulations and free energy calculations
Excerpt:
... epidermal growth factor receptor (EGFR) kinase domain mutations are a common cause of non-small-cell lung cancer (NSCLC), a major subtype of lung cancers. Patients harboring most of these mutations respond well to the EGFR inhibitors Gefitinib and Erlotinib initially, but soon develop resistance to them due to the emergence of the gatekeeper mutation T790M.
