EGFR mutations occur in 30–40% of NSCLC's in Asian populations compared to 10–15% in Western populations. Julie R. Brahmer, MD, co-director of the Upper Aerodigestive Department, Bloomberg Kimmel Institute for Cancer Immunotherapy, and professor of oncology at John Hopkins Medicine, discusses the circumstances in which a physician can choose the third-generation EGFR tyrosine kinase inhibitor (TKI) osimertinib (Tagrisso) over other EGFR TKIs for patients withEGFR-mutant lung cancer. FDA approves ramucirumab plus erlotinib for first-line metastatic NSCLC. Abstract. EGFR-targeted therapies show considerable promise, but drug resistance has become a substantial issue. N Engl J Med. Liquid biopsy analyses of circulating tumor cell-free DNA sequencing performed at the time of disease progression revealed the presence of a new EGFR mutation in exon 20, EGFR M766Q and TP53 V203M and EGFR S306L. Furthermore, similar to later-generation anaplastic lymphoma kinase (ALK) inhibitors, osimertinib has improved efficacy against brain metastases. Dysregulated Pyrimidine Biosynthesis Contributes to 5-FU Resistance in SCLC Patient-Derived Organoids but Response to a Novel Polymeric Fluoropyrimidine, CF10. 2017 Mar;29(2):89-96. doi: 10.1097/CCO.0000000000000350. Patients … It can be used with … The overall response to treatment was 80% with Tagrisso compared to 75% with standard of care treatment. In particular, the mortality rate of with lung cancer reached 39.2/100,000 in 2017. Although various resistance mechanisms have been described, there are currently no FDA-approved therapies that target alternative mechanisms to treat lung tumors with acquired resistance to first-line EGFR TKI agents. The drugs enter the cell and interfere with EGFR from within. Yo… AbTRACTS First-generation EGFR tyrosine kinase inhibitors (EGFR TKI) provide significant clinical benefit in patients with advanced EGFR-mutant (EGFRm+) non–small cell lung cancer (NSCLC). The most common side effects were diarrhea, and skin and nail conditions. Janne PA, Yang JC, Kim DW, Planchard D, Ohe Y, Ramalingam SS, Ahn MJ, Kim SW, Su WC, Horn L, Haggstrom D, Felip E, Kim JH, et al. Int J Mol Sci. 2017;376:917–927. In this comparison, sequential therapy with the earlier-generation EGFR TKI followed by the later-generation TKI after progression with T790M-positivity yielded a greater overall duration of response than the use of later-generation EGFR TKI as the first-line treatment. Zhou W, Ercan D, Chen L, Yun CH, Li D, Capelletti M, Cortot AB, Chirieac L, Iacob RE, Padera R, Engen JR, Wong KK,Eck MJ, et al. Resistance to Tagrisso will ultimately develop in nearly all patients, and subsequent treatment options to overcome this resistance are needed. Serious side effects were also less common in the Tarceva group. It normally helps the cells grow and divide. These patients experienced almost double the PFS—13.6 months in the afatinib group and 6.9 months in the standard chemotherapy group. First-generation EGFR tyrosine kinase inhibitors (EGFR TKI) provide significant clinical benefit in patients with advanced EGFR -mutant (EGFRm+) non–small cell lung cancer (NSCLC). Patients ultimately develop disease progression, often driven by acquisition of a second T790M EGFR TKI resistance mutation. Researchers recently published a case report of a woman undergoing third-line treatment with Tagrisso that developed progressive disease. (10,11). EGFR-independent mechanisms of acquired resistance to AZD9291 in EGFR T790M-positive NSCLC patients. Fully acknowledging the limitations of the cross-trial comparison, this nonetheless illustrates that the superior efficacy of later-generation therapies in the front line may not lead to superior overall survival despite a clearly superior PFS when comparing front-line therapies in isolation. 2013;3:1404–15. Erlotinib (Tarceva) is an EGFR-tyrosine kinase inhibitor (TKI), meaning that it inhibits EGFR by gaining entrance into the cell and … Overall treatment with Tagrisso improved progression-free survival by 54%. EGFR inhibitors are used to treat colon cancer, skin cancer, lung cancer, and pancreatic cancer. Purpose: Given the unprecedented efficacy of EGFR tyrosine kinase inhibitors (TKI) in advanced EGFR-mutant lung cancer, adjuvant TKI therapy is an appealing strategy.However, there are conflicting findings regarding the potential benefit of adjuvant EGFR-TKI in patients with lung cancer harboring EGFR mutations. These drugs work by binding to the malfunctioning receptor proteins in the cell membrane, blocking their activity and therefore stopping the unchecked growth of the cell. The EGFR—which stands for “epidermal growth factor receptor”—contributes to the growth of some lung cancers and drugs that block the activity of EGFR slow cancer growth and prolong survival. J. Clin. In traditional anti-cancer therapy, epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKI) have been proven to be beneficial for patients with EGFR mutations. Many inhibitors of the EGFR … Perez-Soler R. Rash as a surrogate marker for efficacy of epidermal growth factor receptor inhibitors in lung cancer. The targeted agent Gilotrif (afatinib) improves outcomes compared to Tarceva (erlotinib) among patients with squamous cell lung cancer. Imatinib for newly diagnosed patients with chronic myeloid leukemia: Incidence of sustained responses in an intention-to-treat analysis. Randomized Phase II Trial of Gefitinib With and Without Pemetrexed as First-Line Therapy in Patients With Advanced Nonsquamous Non-Small-Cell Lung Cancer With Activating Epidermal Growth Factor Receptor Mutations. 2015;372:2018–28. Initially approved as second line therapy in advanced non–small cell lung cancer (NSCLC) after chemotherapy, first-generation reversible anti-EGFR tyrosine kinase inhibitors (TKI) erlotinib and gefitinib … To compare Tarceva with chemotherapy for the initial treatment of advanced NSCLC that tests positive for an EGFR mutation, researchers conducted a study among 165 patients with Stage IIIB or Stage IV NSCLC. Among patients with an EGFR mutation, Iressa delayed cancer progression to a greater extent than chemotherapy. EGFR INHIBITORS USED TO TREAT LUNG CANCER. NCI CPTC Antibody Characterization Program, Druker B.J., Guilhot F., O’Brien S.G., Gathmann I., Kantarjian H., Gattermann N., Deininger M.W., Silver R.T., Goldman J.M., Stone R.M., et al. This review explores these issues for EGFR inhibitors and other molecularly targeted therapies. Initial treatment with the targeted drug afatinib also prolongs progression-free survival in patients with EGFR-positive advanced lung cancer when compared with standard chemotherapy. AbTRACTSFirst-generation EGFR tyrosine kinase inhibitors (EGFR TKI) provide significant clinical benefit in patients with advanced EGFR-mutant (EGFRm+) non–small cell lung cancer (NSCLC).

Mutations in the epidermal growth factor receptor and in KRAS are predictive and prognostic indicators in patients with non-small-cell lung cancer treated with chemotherapy alone and in combination with erlotinib.  |  All patients were treated with Tagrisso. Research suggests that tumor mutational burden assessment can help predict response to immunotherapy in NSCLC. EGFR inhibitors block the activity of a protein called epidermal growth factor receptor (EGFR). The average duration of response was two-fold higher for patients treated with Tagrisso (17.6 months) compared to standard of care (8.7 months). Zhou C, Wu Y-L, Chen G et al. 2018 Jan 11;378(2):113-125. doi: 10.1056/NEJMoa1713137. doi: 10.1056/NEJMoa1609324. Ann Oncol. 2011;17:1169–80. Preclinical data suggest that EGFR tyrosine kinase inhibitors (TKIs) plus MET TKIs are a possible treatment for EGFR mutation-positive lung cancers with MET-driven acquired resistance.Phase 1 safety data of savolitinib (also known as AZD6094, HMPL-504, volitinib), a potent, selective MET TKI, plus osimertinib, a third-generation EGFR TKI, have provided recommended doses for study. The effect of the EGFR M766Q mutation on sensitivity/resistance to different EGFR TKIs was evaluated preclinically and confirmed. Keedy VL, Temin S, Somerfield MR et al. Tri Le 1 and David E.

Does the natural product, honokiol, have value in the battle against osimertinib resistance? Soria J-C, Enriqueta F, Cobo M, et al. The safety and effectiveness of Tarceva maintenance therapy was evaluated in a Phase III clinical trial known as SATURN. They block the activity of the EGFR protein. Molecular Cell Biology Hypoxia Induces Resistance to EGFR Inhibitors in Lung Cancer Cells via Upregulation of FGFR1 and the MAPK Pathway Yuhong Lu, Yanfeng Liu, Sebastian Oeck, Gary … 2017 Aug 18;8:109-125. doi: 10.2147/LCTT.S119644. The oncogenes directly associated with non-small-cell lung cancer mutations for which treatment is available are: EGFR - accounting for 10–15% of non-squamous non-small cell lung cancers in Western populations , , and anaplastic lymphoma kinase (ALK) which accounts for 3–5% of non-squamous non-small cell lung cancers. Some cancer cells have overactive EGFR pathways, causing cancer cells to replicate and spread to different sites in the body. EGFRs are small proteins that are found on the surface of all cells. Herbst RS, Maddox AM, Rothenberg ML, et al: Selective oral epidermal growth factor receptor tyrosine kinase inhibitor ZD1839 is generally well-tolerated and has activity in non-small-cell lung cancer and … See this image and copyright information in PMC. Theoretical comparison of the overall duration of response with two different sequencing paradigms. 2020 Mar 26;12(4):788. doi: 10.3390/cancers12040788. eCollection 2020 Sep. J Hematol Oncol. Drug Resistance to EGFR Inhibitors in Lung Cancer. There are several FDA-approved medications available to treat EGFR-positive lung adenocarcinoma, as well as one for squamous cell carcinoma and one for EGFR-positive resistant lung cancer. Wang S, Song Y, Liu D. EAI045: The fourth-generation EGFR inhibitor overcoming T790M and C797S resistance. Guidelines from the International Association for the Study of Lung Cancer (IASLC) have been developed and they recommend EGFR mutation testing at initial diagnosis of all lung cancer patients. Why are EGFR Inhibitors … At the time of data analysis, median overall survival and progression-free survival was greater in the group of patients treated with afatinib than the group treated with Tarceva. * The oldest and most widely used and effective EGFR inhibitor is Tarceva (erlotinib). OBJECTIVES: Epidermal Growth Factor Receptor (EGFR) and Anaplastic Lymphoma Kinase (ALK) Tyrosine Kinase Inhibitors (TKIs) are the preferred treatment option for patients with advanced/metastatic non-small cell lung cancer … (1). 2015;26:2073–8. J. Med. (33), The PD-1/PD-L1 checkpoint inhibitor precision cancer immunotherapies, Opdivo (nivolumab) and Keytruda (pembrolizumab) have become the standard of care for advanced NSCLC. Progression-free survival (PFS) for first-line erlotinib is drawn from the phase 3 EURTAC trial, which compared erlotinib to conventional chemotherapy in the first-line setting [15]. Abstract 9007. The median progression-free survival was 16.5 months with Tagrisso compared to 11.0 months for the standard therapy. For example Avastin combined with Tarceva improved progression free survival by 9-10 months when used as first or second line treatment for advanced EGFR + NSCLC. The cancer cells however were sensitive to treatment with low concentrations of Nerlynx (neratinib) and clinically achievable doses of poziotinib, an investigational, irreversible pan-HER TKI targeting EGFR and HER2 with exon 20 insertion mutations. The EGFR—which stands for “epidermal growth factor receptor”—contributes to the growth of some lung cancers and drugs that block the activity of EGFR slow cancer growth and prolong survival. Ramalingam SS, Vansteenkiste J, Planchard D, Cho BC, Gray JE, Ohe Y, Zhou C, Reungwetwattana T, Cheng Y, Chewaskulyong B, Shah R, Cobo M, Lee KH, Cheema P, Tiseo M, John T, Lin MC, Imamura F, Kurata T, Todd A, Hodge R, Saggese M, Rukazenkov Y, Soria JC; FLAURA Investigators. The Avastin EGFR-TKI combinations have exhibited significant effectiveness in unselected NSCLC patients. EGFR inhibitors used for squamous cell NSCLC Necitumumab (Portrazza) is a monoclonal antibody (a man-made version of an immune system protein) that targets EGFR. Arcila ME, Oxnard GR, Nafa K, Riely GJ, Solomon SB, Zakowski MF, Kris MG, Pao W, Miller VA, Ladanyi M, et al. Activating mutations in the epidermal growth factor receptor gene occur as early cancer-driving clonal events in a subset of patients with non-small cell lung cancer (NSCLC) and result in increased sensitivity to EGFR-tyrosine-kinase-inhibitors (EGFR-TKIs). Fukuoka M, Wu Y-L, Thongprasert S et al. Tetsu O, Hangauer MJ, Phuchareon J, Eisele DW, McCormick F. BACKGROUND: The discovery of mutations in epidermal growth factor receptor (EGFR) has dramatically changed the treatment of patients with non-small-cell lung cancer (NSCLC), the leading cause of cancer … Soria JC, Ohe Y, Vansteenkiste J, Reungwetwattana T, Chewaskulyong B, Lee KH, Dechaphunkul A, Imamura F, Nogami N, Kurata T, Okamoto I, Zhou C, Cho BC, Cheng Y, Cho EK, Voon PJ, Planchard D, Su WC, Gray JE, Lee SM, Hodge R, Marotti M, Rukazenkov Y, Ramalingam SS; FLAURA Investigators. The identification of EGFR as an oncogene has led to the development of anticancer therapeutics directed against EGFR (called "EGFR inhibitors"), including gefitinib, erlotinib, afatinib, brigatinib and icotinib for lung cancer, and cetuximab for colon cancer. Update on the management of early stage NSCLC with precision medicines - immunotherapy. N Engl J Med. USA.gov. Advances in cancer research have highlighted the importance of understanding the specific characteristics of each person’s cancer. Median survival without cancer progression was 13.1 months among patients treated with Tarceva and 4.6 months among patients treated with chemotherapy. Gilotrif was particularly beneficial to the 308 patients who had one of two common types of EGFR mutations (deletion 19 or L858R) that account of approximately 90 percent of all EGFR mutations. EGFR inhibitors are used to treat colon cancer, skin cancer, lung cancer, and pancreatic cancer. Keep up with the growing number of precision medicines targeting specific mutations in lung cancer. Online ahead of print. The authors declare no conflict of interest. Despite the high response rate to EGFR TKIs in EGFR-mutant lung cancer, resistance and … Background. The median PFS for osimertinib after progression on EGFR TKIs in T790M-negative patients was derived from the AURA trial [60]. 2020 Oct 27;13(1):143. doi: 10.1186/s13045-020-00977-0. A second clinical trail compared treatment with Tagrisso to standard treatment with Tarceva or Iressa as first line therapy in 556 patients from Asia, Europe, and North America with NSCLC and EGFR mutations. Third generation EGFR TKIs provide benefit in patients who progressed after treated with other EGFR TKIs especially in the T790M mutation-positive patients. Updated June 1, 2020. www.fda.gov/drugs/drug-approvals-and-databases/fda-approves-ramucirumab-plus-erlotinib-first-line-metastatic-nsclc. Oncol. Maintenance therapy refers to treatment that is given after initial treatment but before cancer progression. Compared with a placebo, overall survival was 23% better among patients treated with Tarceva, and progression-free survival was 41% better. The median PFS for osimertinib after progression on early-generation EGFR TKIs in T790M-positive patients was derived from the AURA3 trial [55]. Jänne PA, et al. Planchard D, Loriot Y, André F, Gobert A, Auger N, Lacroix L, Soria JC. Biomarker analysis and final overall survival results from a phase III, randomized, open-label, first-line study of gefitinib versus carboplatin/paclitaxel in clinically selected patients with advanced non-small-cell lung cancer in Asia (IPASS). Clin Cancer Res. This leads to the uncontrolled and excessive growth of the cancer cell. The researchers concluded that Gilotrif appears to be an effective treatment option for patients with advanced squamous cell lung cancer. Accessed June 1, 2020.
