Optimizing the Therapeutic Dose of Apatinib Mesylate Tablets in Patients With Lung Cancer by Dose Titration：A Real World Exploratory Study

Not Applicable

• Conditions: NSCLC Stage IV; NSCLC Stage IIIB
• Interventions: Other: Intervention/treatment

• Registration Number: NCT03594682
• Lead Sponsor: Beijing Chest Hospital

Brief Summary

The purpose of the study is to evaluate the safety and efficacy of two different administration methods of apatinib in NSCLC patients.

Detailed Description

1. Aged ≥18；

2. Locally advanced/metastatic non-small lung cancer (IIIb/IV) confirmed by pathology with measurable lesions；

3. Patients with wild type EGFR/ALK must received two kinds of systemic chemotherapy before；Patients with EGFR mutation positive had experienced treatment failure with TKI in first line and Chemotherapy in second line ；

4. ECOG：0-4；

5. The subjects were treated with other drugs has been restored (NCI CTCAE version 4.0 class 1 or less), which accept nitroso urea or mitomycin interval 6 weeks or more; Accept other cytotoxic drugs, bevacizumab (Avastin) (except local palliative radiotherapy), radiotherapy or surgery four weeks or more. EGFR TKI ≥2 weeks; Main organs function is normal；

6. Fertile woman must perform a pregnancy test (serum or urine) 7 days before screened, or voluntarily adopt proper methods of contraception during the observation period and 8 week after the last given apatinib. For man, surgical sterilization should be performed, or voluntarily adopt proper methods of contraception during the observation period and 8 week after the last given apatinib；

7. Patients voluntarily entered the study and signed informed consent form (ICF).

Arm && Interventions

Group	Intervention	Description
non-titration group	Intervention/treatment	Patients were given 750mg qd apatinib until disease progression or intolerance
dose titration group	Intervention/treatment	First of all, according to the patient's weight and ECOG score, patients were divided into three groups（the initial dose of 250 mg qd,250 mg/500 mg qd by turns, 500 mg qd）. in two weeks, if the patient who is intolerant of the initial dose,250mg qod,250mg qd ,250mg qd was selected. if the patient can tolerate the dose well,a high-dose was given,and the maximum dose does not exceeding 750mg qd.

Primary Outcome Measures
