Provided herein are methods of selecting cancer patients for treatment with quinazoline-based tyrosine kinase inhibitors, either alone or in combination with anti- HER2/HER3 antibodies, as well as methods of treating cancer patients so selected. Cancer patients are selected for treatment if their cancer has an NRG1 fusion. Selected patients are then treated with quinazoline-based tyrosine kinase inhibitors alone or in combination with anti -HER2/HER3 antibodies.

Tyrosine Kinase Inhibitors. 20. Optimization of Substituted Quinazoline and Pyrido[3,4-d]pyrimidine Derivatives as Orally Active, Irreversible Inhibitors of the Epidermal Growth Factor Receptor Family

Structure-activity relationships for inhibition of erbB1, erbB2, and erbB4 were determined for a series of quinazoline- and pyrido[3,4-d]pyrimidine-based analogues of the irreversible pan-erbB inhibitor, canertinib. Cyclic amine bearing crotonamides were determined to provide rapid inhibition of cellular erbB1 autophosphorylation and good metabolic stability in liver microsome and hepatocyte assays. The influence of 4-anilino substitution on pan-erbB inhibitory potency was investigated. Several anilines were identified as providing potent, reversible pan-erbB inhibition. Optimum 4- and 6-substituents with known 7-substituents provided preferred irreversible inhibitors for pharmacodynamic testing in vivo. Quinazoline 54 and pyrido[3,4-d]pyrimidine 71 were identified as clearly superior to canertinib. Both compounds possess a piperidinyl crotonamide Michael acceptor and a 3-chloro-4-fluoroaniline, indicating these as optimized 6- and 4-substituents, respectively. Pharmacokinetic comparison of compounds 54 and 71 across three species selected compound 54 as the preferred candidate. Compound 54 (PF-00299804) has been assigned the nomenclature of dacomitinib and is currently under clinical evaluation.

Potent and Selective Inhibitors of Platelet-Derived Growth Factor Receptor Phosphorylation. 3. Replacement of Quinazoline Moiety and Improvement of Metabolic Polymorphism of 4-[4-(N-Substituted (thio)carbamoyl)-1-piperazinyl]-6,7-dimethoxyquinazoline Derivatives

We have previously reported that a series of 4-[4-(N-substituted (thio)carbamoyl)-1-piperazinyl]-6,7-dimethoxyquinazoline derivatives were potent and selective inhibitors of platelet-derived growth factor receptor (PDGFR) phosphorylation and demonstrated several biological effects such as suppression of neointima formation following balloon injury in rat carotid artery by oral administration. Here, we investigated structure-activity relationships of the 6,7-dimethoxyquinazolinyl moiety. In regard to 6,7-dimethoxy groups, ethoxy analogues showed potent activity (IC50 of 16b is 0.04 μM; IC50 of 17a is 0.01 μM) and further extension of the alkyl group reduced activity. Interestingly, methoxyethoxy (IC50 of 16j is 0.02μM; IC50 of 17h is 0.01 μM) and ethoxyethoxy (IC50 of 17j is 0.02 μM) analogues showed the most potent activity, suggesting that the inserted oxygen atom significantly interacts with β-PDGFR. Among tricyclic quinazoline derivatives, the 2-oxoimidazo[4,5-e]quinazoline derivative 21a showed potent activity (IC 50 = 0.10 μM). Regarding replacements of quinazoline by other heterocyclic rings, pyrazolo[3,4-d]pyrimidine (39a, IC50 = 0.17 μM) and quinoline (IC50 of 40a is 0.18 μM; IC50 of 40b is 0.09 μM) derivatives showed potent activity. Isoquinoline and some pyridopyrimidine derivatives were completely inactive; therefore, 1-aza has an important role. Also 7-aza and 8-aza substitution on the parent quinazoline ring has a detrimental effect on the interaction with β-PDGFR. We also demonstrated that the substituents on the quinazoline ring possess major consequences for metabolic polymorphism. Although there existed extensive metabolizers and poor metabolizers in Sprague-Dawley rats administrated 6,7-dimethoxyquinazoline derivatives (1b and 1c), 6-(2-methoxy)ethoxy-7-methoxyquinazoline analogue 16k showed no metabolic polymorphism.
