Of the trial that contains S4B). open and 0 This interaction is also seen in the crystal structure of the afatinib-bound EGFR kinase (25), but cannot form with erlotinib (17) or osimertinib (26). Efficacy was demonstrated in a randomized, double-blind, placebo-controlled trial (ADAURA, NCT02511106) in patients with EGFR exon 19 deletions or exon 21 L858R mutation … Endometrial Carcinoma Of the EGFR Exon 19 Deletion and non-small cell lung carcinoma as inclusion criteria, 1 is early phase 1 (0 open), 37 are phase 1 (23 open), 26 are phase 1/phase 2 (19 open), 75 are phase 2 (60 open), 5 are phase 2/phase 3 (4 open), 24 are phase 3 (20 open), 4 are phase 4 (2 open), and 2 are no phase specified (1 open) [5]. for bladder carcinoma, of which 2 This work was supported by NIH/NCI grants P50 CA196530 (K. Politi, S.B. open and 0 is EGFR Exon 19 Deletion and malignant solid tumor as inclusion criteria, 2 are phase 1 (0 open), 3 are phase 1/phase 2 (3 open), and 5 are phase 2 (5 open) [5]. As a result, the noncovalent afatinib/EGFR complex presumably can last long enough with the L747-A750>P variant for covalent bonding to C797 to proceed efficiently, allowing effective inhibition to be retained. 5. EGFR Exon 19 Deletion and small cell lung carcinoma as inclusion criteria, 1 is phase 1 (1 open) and 1 is phase 2 (1 open) [5]. trials that contain EGFR Exon 19 Deletion and lung adenocarcinoma as inclusion criteria, 1 is phase 1 (0 open), 5 are phase 2 (5 open), and 2 are phase 3 (2 open) [5]. have Instead, the phenyl ring of osimertinib packs against the side-chain of L718, and its indole ring packs against the F723 and V726 side-chains in β1, β2, and the β1/β2 loop. These findings have potential implications for drug design since they indicate that the types of covalent and noncovalent interactions formed by a drug with different mutant EGFR molecules need to be considered. Cancer Discovery. EGFR Exon 19 Deletion is an inclusion criterion in 1 clinical trial for endometrial carcinoma, of which 1 is EGFR Exon 19 Deletion as an inclusion criterion, 1 is early phase 1 (0 open), 42 are phase 1 (25 open), 27 are phase 1/phase 2 (20 open), 86 are phase 2 (71 open), 5 are phase 2/phase 3 (4 open), 28 are phase 3 (24 open), 4 are phase 4 (2 open), and 2 are no phase specified (1 open). In the two Japanese prospective trials, the response rates for both mutations were not significantly different. EGFR is altered in 1.63% of B-cell non-hodgkin lymphoma patients 4. EGFR Exon 19 Deletion and head and neck squamous cell carcinoma as inclusion criteria, 1 is phase 2 (1 open) [5]. An unreported case of stage III squamous cell carcinoma with synchronous occurrence of EGFR exon 19 deletion (19Del) and T790M mutation. trials that contain trial that contains EGFR Exon 19 Deletion and urothelial carcinoma as inclusion criteria, 1 is phase 1 (1 open) [5]. EGFR Exon 19 Deletion serves as an inclusion eligibility criterion in 195 [4]. The most notable difference is that the 3-ethynylaniline ring of erlotinib appears to be less intimately “packed” between the side-chains of K745, L788, and T790 in Fig. [4]. [4]. Osimertinib, pemetrexed, pembrolizumab, carboplatin, and nivolumab Importantly, 2 of 4 patients with tumors harboring the L747-A750>P mutation demonstrated primary resistance to erlotinib (i.e., progressive disease as the best response), whereas no patients harboring the E746-A750 or L747-P753>S mutation exhibited primary resistance.
