About

Gemcitabine plus cisplatin (GC) is more effective than fluorouracil plus cisplatin in the treatment of recurrent or metastatic NPC (R/M-NPC). GC is the standard first-line chemotherapy regimen for this population. However, the median progression-free survival was only 7 months for GC regimen. Anlotinib is a kinase inhibitor of receptor tyrosine with multi-targets, especially for VEGFR2、VEGFR3、PDGFRβ and c-Kit, which has strong effect of anti-angiogenesis. This study is aim to evaluate the efficacy and safety of the combination regimen of anlotinib plus GC as first-line treatment for R/M-NPC.

Full description

In the phase Ib portion, an escalated dose cohort is recruited to determine the maximum tolerated dose (MTD) and recommended phase II dose (RP2D) of anlotinib when given in combination with gemcitabine/cisplatin. The phase II portion is designed to characterize the efficacy and safety of the combination therapy in previous untreated patients with R/M-NPC.

Exclusion criteria

1. Other malignancy within the past five years other than basal cell skin cancer, or carcinoma in situ of the cervix;
2. Factors affecting the oral medication (e.g. inability to swallow, chronic diarrhea and intestinal obstruction);
3. Major injuries and/or surgery ≤ 4 weeks prior to registration with incomplete wound healing.
4. Patients with poor-controlled arterial hypertension (systolic pressure ≥ 140 mmHg and/or diastolic pressure ≥ 90 mm Hg) despite standard medical management;
5. Suffered from grade II or above myocardial ischemia or myocardial infarction, uncontrolled arrhythmias. Grade III-IV cardiac insufficiency according to New York Heart Association (NYHA) criteria or echocardiography check: left ventricular ejection fraction (LVEF)<50%;

9. Treatment with other investigational drugs or other anti-cancer therapy;
10. Previous therapy with anti-angiogenic drugs (such as anlotinib, apatinib, bevacizumab, endostar, etc.)
11. Treatment in another investigational trial ≤ 4 weeks prior to registration;
12. History of hypersensitivity to anlotinib, gemcitabine, cisplatin and/or the excipients of the trial drugs;
13. Active or chronic hepatitis C and/or B infection, or other active uncontrolled infection;

17. Evidence of significant medical illness that in the investigator's judgment will substantially increase the risk associated with the subject's participation in and completion of the study;
18. History of mental diseases;
19. Other conditions regimented at investigators' discretion.

Anlotinib plus gemcitabine/cisplatin

Experimental group

Description:

In the phase Ib portion, patients received dose escalation of anlotinb (from 8mg to 12mg orally once daily on days 1-14 of a 21-day) in combination with fixed dose of gemcitabine (1000mg/m2 intravenously on days 1 and 8) and cisplatin (80mg/m2 intravenously on day 1) every 3 weeks. In the phase II portion, patients received anlotinb at recommended phase II dose determined in the phase Ib portion, in combination with fixed dose of gemcitabine and cisplatin every 3 weeks. The combination of anlotinib plus gemcitabine / cisplatin was repeated every 3 weeks for up to six cycles. Patients with disease control (defined as a complete response, a partial response, or stable disease) continue to receive anlotinb until disease progression or unacceptable toxic effects, whichever occurred first.
