After considering the company's project situation and strategic development direction, it has been decided to terminate this project. The experiment will be terminated for non safety reasons.

This is a study to evaluate the tolerance, dose-limiting toxicity (DLT), and maximum tolerated dose (MTD) of single and multiple oral doses of TQ-A3334 and observe the efficacy of TQ-A3334 in combination with anlotinib capsules in patients with non-small cell lung cancer.

• In addition to the above criteria, the extended research phase must meet the following criteria: epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) are negative; or patients with positive test results of EGFR and ALK are resistant or intolerant after receiving the targeted drug treatment.

• Has multiple factors affecting oral medication

• Has any severe acute complications before the first administration

• Have participated in other clinical trials within 4 weeks before the first administration

• According to the judgement of the researchers, there are other factors that may lead to the termination of the study

  2. EGFR and ALK are positive untreated with relevant targeted drugs;
