Anlotinib Hydrochloride Combined With AP in Stage IIIB/IIIC/IV Non-squamous Non-small-cell Lung Cancer

Study Overview
=================
Brief Summary
-----------------
Anlotinib is a novel oral multitarget tyrosine kinase inhibitor and primary targeted to VEGFR, FGFR, PDGFR and c-Kit. The ALTER-0303 trial showed that patients with advanced non-small cell lung cancer (NSCLC) who received anlotinib as third-line or further therapy had more survival benefit. Pemetrexed plus platinum-based chemotherapy (AP) was long considered as the first line treatment in non-squamous NSCLC patients with negative driver mutation. In this dose exploration study, the primary objective is to establish the safety profile of anlotinib combined with AP in non-squamous NSCLC patients by identifying dose limiting toxicity (DLT), maximum tolerance dose (MTD), the recommended phase II dose, and schedule. Secondary objective includes the assessment of preliminary antitumor effect.

Detailed Description
-----------------
Anlotinib, a new small molecule inhibitor of multiple receptor tyrosine kinases targeting the vascular endothelial growth factor receptor (VEGFR), fibroblast growth factor receptor (FGFR), platelet-derived growth factor receptor (PDGFR) and c-Kit,8,9 has been approved as a third-line treatment for refractory advanced NSCLC by the China Food and Drug Administration (CFDA) on May 9, 2018.10 Previous study in phase II (ALTER0302) trial has shown a better progression-free survival (PFS) in advanced NSCLC patients treated with anlotinib compared those with the placebo (4.8 vs 1.2 months, P<0.0001).11 In phase III (ALTER0303) trial, both the overall survival (OS) and PFS of advanced NSCLC patients were observed to be significantly longer in the anlotinib group (median, 9.6 and 5.4 months) than the placebo group (median, 6.3 and 1.4 months).12 Moreover, anlotinib also displayed manageable toxicity, long circulation, and broad-spectrum antitumor potential.13,14 For the lack of recommended drugs with exactly therapeutic effect in the third-line treatment of SCC patients, it is worth to further analyze the efficacy and specifically clinical observation indicator of anlotinib in this subtype of NSCLC patients. In this dose exploration study, the primary objective is to establish the safety profile of anlotinib combined with AP in treatment-naive non-squamous NSCLC patients by identifying dose limiting toxicity (DLT), maximum tolerance dose (MTD), the recommended phase II dose, and schedule. Secondary objective includes the assessment of preliminary antitumor effect.

Female patients of childbearing age agree that contraceptive measures must be used within the study period and within 8 weeks after the end of the study drug treatment. The serum or urine test indicates unpregnancy within 7 days prior to the study. Male patients agree to have contraceptive use during the study period and within 8 weeks after the end of the study period or have had surgical sterilization. Exclusion Criteria: Patients with small cell lung cancer (including small cell carcinoma and non-small cell carcinoma mixed lung cancer) and lung adenosquamous carcinoma mixed with squamous carcinoma; Active brain metastases, cancerous meningitis, spinal cord compression, or imaging CT or MRI screening for brain or pia mater disease (a patient with brain metastases who have completed treatment and stable symptoms in 21 days before enrollment may be enrolled, but should be confirmed by brain MRI, CT or venography evaluation as no cerebral hemorrhage symptoms); Imaging (CT or MRI) shows that the distance between tumor lesion and the large blood vessel is ≤ 5 mm, or there is a central tumor that invades the local large blood vessel and the distance between tumor and bronchial tree is ≤ 2 cm; or there is a significant pulmonary cavity or necrotizing tumor; Uncontrollable hypertension (systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg after optimal medical treatment); Suffering from severe cardiovascular disease: myocardial ischemia or myocardial infarction above grade II, poorly controlled arrhythmias (including men with QTc interval ≥ 450 ms, women ≥ 470 ms); according to NYHA criteria, grades III to IV Insufficient function, or cardiac color Doppler ultrasound examination indicates left ventricular ejection fraction (LVEF) <50%; Abnormal blood coagulation (INR > 1.5 or prothrombin time (PT) > ULN + 4 seconds or APTT > 1.5 ULN), with bleeding tendency or undergoing thrombolytic or anticoagulant therapy; Urine routine test protein ≥++, and confirmed 24 hours urine protein> 1.0 g; There is currently a peripheral neuropathy of ≥CTCAE 2 degrees, except for trauma; Respiratory syndrome (≥CTC AE grade 2 dyspnea), serous effusion (including pleural effusion, ascites, pericardial effusion) requiring surgical treatment; Long-term unhealed wounds or fractures; Serious infection (≥CTC AE Level 2 infection) requiring systemic antibiotics; decompensated diabetes or other ailments treated with high doses of glucocorticoids; Active or chronic hepatitis C or/and hepatitis B infection; Factors that have a significant impact on oral drug absorption, such as inability to swallow, chronic diarrhea, and intestinal obstruction; Patients have undergone major surgery within 4 weeks before enrollment or have severe trauma, fracture and ulcer; Severe weight loss (greater than 10%) within 6 weeks prior to enrollment; Clinically significant hemoptysis (daily hemoptysis greater than 50ml) within 3 months prior to enrollment; or significant clinically significant bleeding symptoms or defined bleeding tendency, such as gastrointestinal bleeding, hemorrhagic gastric ulcer, baseline fecal occult blood ++ and above, or suffering from vasculitis; Events of venous/ arterious thrombosis occurring within the first 12 months prior to enrollment, such as cerebrovascular accidents (including transient ischemic attacks, cerebral hemorrhage, cerebral infarction), deep vein thrombosis, and pulmonary embolism; Patients have contraindication to platinum drugs (cisplatin/carboplatin) and cytotoxic drug (Pemetrexed); Patients have anaphylactic reaction due to anlotinib Hydrochloride or the excipient in investigational drug.
