Selective EGFR TKIs

Janne et al., ASCO 2014

AZD-9298

Selective EGFR TKIs

Lynch et al., ASCO 2014

Selective EGFR TKIs: Conclusions• High response rates and extended PFS after failure

of first-generation EGFR TKIs• Higher response rates in T790M+• Toxicity patterns consistent with selectivity to

mutant receptors

Crossover rate of 64% in the chemotherapy arm

Ceritinib in ALK+ Patients


Response rates:• 56% crizotinib-treated patients• 62% crizotinib-naïve patients

Response rates:• 86% ALK-dependant resistance• 59% non ALK-dependant resistance

ALK Inhibitors: Conclusions• Crizotinib improves PFS over pemetrexed/platinum in

treatment-naïve ALK+ patients• Crizotinib improves response rates, PFS and QoL over

pemetrexed or docetaxel in previously treated ALK+ patients. No improvements on premature analysis of OS, in the setting of high crossover rate (64%)

• Pemetrexed has better response rates and PFS compared to docetaxel in ALK+ patients

• Second generation ALK inhibitors have high response rates in crizotinib-naïve and crizotinib-treated patients, including responses in the brains

• Best strategy as regards to sequencing of ALK inhibitors and chemotherapy to be determined

Targeted agents for driver molecular alterations

Targeted Agents for Driver Molecular Alterations

• Crizotinib is active in ROS-1 positive tumors• Dabrafenib is active in patients with a BRAF V600E activating

mutation• Dasatinib may be active in patients with a BRAF inactivating

mutation• MEK inhibitors with modest activity in difficult to treat, KRAS

positive patients• Preliminary evidence of activity of HER-2 targeting with

trastuzumab, afatinib, but not lapatinib, in HER-2 mutant tumors

• Cabozantinib may be active in RET positive tumors• Metmab + erlotinib may improve PFS and OS comapred to

erlotinib in MET positive patients. Phase III results pending.

Take Home Messages

• Treatment with agents targeting driver alterations may result in promising activity for molecularly-defined subgroups of patients

• Targetable mutations more frequently identified in adenocarcinomas, compared to squamous cell carcinomas

• Precision medicine for NSCLC treatment is here to stay
