Evaluate the efficacy and safety of Anlotinib Hydrochloride in combination with Pemetrexed and Carboplatin versus Pemetrexed and Carboplatin for advanced or locally-advanced Osimertinib-resistant non-squamous non-small cell lung cancer.

Anlotinib Hydrochloride in combination with Pemetrexed and Carboplatin use 4 cycles,then continue pem and anlotinib until PD

Pemetrexed and Carboplatin use 4 cycles,then continue pem until PD

TO see the different of PFS and OS and safety between the two group
