Clinical Effectiveness of Erlova in EGFR-Mutated Non-Small Cell Lung Cancer: An Affordable Price with Clinical Benefit.

BACKGROUND: Thyrosin kinase inhibitors (TKIs) is approved for the first line treatment of non-small cell lung cancer (NSCLC) patients with  epidermal growth factor receptor (EGFR) mutation. This study performed to assess clinical effectiveness and safety of Erlova (generic form of Erlotinib). METHODS: Somatic mutations of EGFR gene were studied in tumor tissue by polymerase chain reaction (PCR) and bi-directional sequencing in 513 chemonaive and histologically verified lung adenocarcinoma Iranian patients. Patients  with EGFR mutation received Erlova at 150 mg/day  as first line treatment. Primary endpoint was progression free survival (PFS). RESULTS: About 21% (n=109) cases had EGFR mutation. Most EGFR mutations were  occurred at exon 19. Among them, sixty nine patients treated with Erlova. Median PFS was 11.4 months and objective response rate (ORR) was about  88%. Most frequent treatment related adverse events was  skin rash. CONCLUSION: Our findings showed Erlova had remarkable effectiveness. In  mutation-positive patients with EGFR, Erlova can be used  safely instead of  other tyrosine-kinase inhibitors.

A Phase IV Efficacy Study of Formeta Plus Carboplatin as First-Line Treatment of Advanced Non-Squamous, Non-Small Cell Lung Cancer in Iran: An Affordable Price with Clinical Benefit

Background: This study performed to assess the efficacy and safety of Formeta (generic form of Pemetrexed) plus Carboplatin as first-line chemotherapy in advanced stage, non- squamous, non small cell lung cancer ( NSCLC) in Iran. Methods: This was a post marketing single-arm phase IV efficacy study of Formeta (manufactured by Oncomed.,Czech Republic ) and Carboplatin in chemo-naive advanced non-squamous NSCLC Iranian patients. Patients received up to six cycles of Formeta (500 mg/m2) combined with Carboplatin (area under the curve: AUC 5) every 3 weeks. The primary endpoint was the progression free survival (PFS) and secondary endpoints were safety and overall survival (OS). Results: Fifty-two patients were enrolled between June 2014 to January 2016, and 44 patients were evaluable for both safety and efficacy. Partial and complete responses were achieved in 19 (36.5 %) and 2 (3.8%) patients, respectively as well as stable disease in 8 patients (15.3 %). Median of PFS and OS were 7.9 ± 1.1 months and 12.43±0.6 months, respectively. Anemia was the most prevalent adverse events of this regimen. Grades 3 or 4 of adverse events were not observed in any patients. Non-hematologic and other grades of hematologic toxicities were generally mild, and there were no treatment-related deaths. Conclusion: The combination of Formeta and Carboplatin was effective in advanced non-squamous NSCLC and can be a suitable candidate as first-line treatment in these patient's population.
