Pazopanib and sunitinib have similar efficacy, but the safety and quality-of-life profiles favor pazopanib. (Funded by GlaxoSmithKline Pharmaceuticals; COMPARZ ClinicalTrials.gov number, NCT00720941.).
Lapatinib plus paclitaxel demonstrated activity in the second-line treatment of patients with HER2 FISH-positive IHC3+ advanced gastric cancer but did not significantly improve OS in the intent-to-treat population.
BackgroundAnlotinib is a novel multi-target tyrosine kinase inhibitor that is designed to primarily inhibit VEGFR2/3, FGFR1-4, PDGFR α/β, c-Kit, and Ret. We aimed to evaluate the safety, pharmacokinetics, and antitumor activity of anlotinib in patients with advanced refractory solid tumors.MethodsAnlotinib (5–16 mg) was orally administered in patients with solid tumor once a day on two schedules: (1) four consecutive weeks (4/0) or (2) 2-week on/1-week off (2/1). Pharmacokinetic sampling was performed in all patients. Twenty-one patients were further enrolled in an expanded cohort study on the recommended dose and schedule. Preliminary tumor response was also assessed.ResultsOn the 4/0 schedule, dose-limiting toxicity (DLT) was grade 3 hypertension at 10 mg. On the 2/1 schedule, DLT was grade 3 hypertension and grade 3 fatigue at 16 mg. Pharmacokinetic assessment indicated that anlotinib had long elimination half-lives and significant accumulation during multiple oral doses. The 2/1 schedule was selected, with 12 mg once daily as the maximum tolerated dose for the expanding study. Twenty of the 21 patients (with colon adenocarcinoma, non-small cell lung cancer, renal clear cell cancer, medullary thyroid carcinoma, and soft tissue sarcoma) were assessable for antitumor activity of anlotinib: 3 patients had partial response, 14 patients had stable disease including 12 tumor burden shrinkage, and 3 had disease progression. The main serious adverse effects were hypertension, triglyceride elevation, hand-foot skin reaction, and lipase elevation.ConclusionsAt the dose of 12 mg once daily at the 2/1 schedule, anlotinib displayed manageable toxicity, long circulation, and broad-spectrum antitumor potential, justifying the conduct of further studies.Electronic supplementary materialThe online version of this article (doi:10.1186/s13045-016-0332-8) contains supplementary material, which is available to authorized users.
The prognosis for patients with refractory soft-tissue sarcoma (STS) is dismal. Anlotinib has previously shown antitumor activity on STS in preclinical and phase I studies. Patients 18 years and older, progressing after anthracycline-based chemotherapy, naïve from angiogenesis inhibitors, with at least one measurable lesion according to RECIST 1.1, were enrolled. The main subtypes eligible were undifferentiated pleomorphic sarcoma (UPS), liposarcoma (LPS), leiomyosarcoma (LMS), synovial sarcoma (SS), fibrosarcoma (FS), alveolar soft-part sarcoma (ASPS), and clear cell sarcoma (CCS). Participants were treated with anlotinib. The primary endpoint was progression-free rate at 12 weeks (PFR). A total of 166 patients were included in the final analysis. Overall, the PFR was 68%, and objective response rate was 13% (95% confidence interval, 7.6%-18%). The median progression-free survival (PFS) and overall survival (OS) were 5.6 and 12 months, respectively. The PFR, median PFS and OS were: 58%, 4.1 and 11 months for UPS ( = 19); 63%, 5.6 and 13 months for LPS ( = 13); 75%, 11 and 15 months for LMS ( = 26); 75%, 7.7 and 12 months for SS ( = 47); 81%, 5.6 and 12 months for FS ( = 18); 77%, 21 and not reached for ASPS ( = 13); 54%, 11 and 16 months for CCS ( = 7); and 44%, 2.8 and 8.8 months for other sarcoma ( = 23), respectively. The most common clinically significant grade 3 or higher adverse events were hypertension (4.8%), triglyceride elevation (3.6%), and pneumothorax (2.4%). No treatment-related death occurred. Anlotinib showed antitumor activity in several STS entities. The toxicity was manageable. .
BackgroundIn the AVAGAST study, fluoropyrimidine and cisplatin plus bevacizumab did not significantly improve overall survival (OS) versus fluoropyrimidine and cisplatin plus placebo in patients with advanced gastric cancer. Geographic differences in efficacy were observed in AVAGAST, but the study only included 12 Chinese patients. AVATAR, a study similar in design to AVAGAST, was a randomized, double-blind, phase III study conducted in Chinese patients with advanced gastric cancer.MethodsPatients more than 18 years of age with gastric adenocarcinoma were randomized 1:1 to capecitabine–cisplatin plus either bevacizumab or placebo. The primary endpoint was OS; secondary endpoints included progression-free survival (PFS) and safety.ResultsIn total, 202 patients were included (placebo n = 102; bevacizumab n = 100). Baseline characteristics were well balanced. The primary analysis result did not show a difference in OS for the bevacizumab arm compared to the placebo arm [hazard ratio, 1.11 (95 % CI, 0.79–1.56); P = 0.5567]. Median PFS was also similar in both arms. Bevacizumab plus capecitabine–cisplatin was well tolerated. Grade 3–5 adverse events (AEs) occurred in 60 % of bevacizumab-treated and 68 % of placebo-treated patients, respectively. Grade 3–5 AEs of special interest with bevacizumab occurred in 8 % of bevacizumab-treated patients and 15 % of placebo-treated patients, mainly grade 3–5 hemorrhage (bevacizumab 4 %, placebo 12 %).ConclusionsAddition of bevacizumab to capecitabine–cisplatin in Chinese patients with advanced gastric cancer did not improve outcomes in AVATAR. There was no difference in OS between the two arms and PFS was similar in both arms. Safety findings were as previously experienced with bevacizumab, including AVAGAST; no new safety signals were reported.
SCEC is systemic disease. Tumor stage and chemotherapy were independent prognostic factors. Systemic therapy, based on chemotherapy with radiotherapy, is recommended.
BackgroundThe ToGA study showed that trastuzumab plus chemotherapy prolonged median survival in patients with human epidermal growth factor receptor 2 (HER2)-positive advanced gastric cancer. Among chemotherapy options, oxaliplatin might be as effective as cisplatin but has shown to be more tolerable. To further improve treatment options for patients with advanced gastric cancer, we initiated a study to evaluate the efficacy and safety of trastuzumab plus oxaliplatin/capecitabine in patients with HER2-positive advanced gastric cancer.MethodsCGOG1001 was an open-label, multicenter, prospective phase II study. Patients with chemotherapy-naive HER2-positive advanced gastric cancer were eligible. Trastuzumab was administered at a loading dose of 8 mg/kg followed by 6 mg/kg infusion every 3 weeks (q3w). Oxaliplatin was administrated as a 130 mg/m2 infusion, q3w, for up to 6 cycles. Capecitabine 1000 mg/m2 was given orally twice daily on days 1–14 followed by a 7-day rest interval. Trastuzumab and capecitabine were continued until disease progression or intolerable toxicity. The primary endpoint was objective response rate. Simon two-stage design (H0 = 40 %, H1 = 60 %, α = 0.05, β = 0.2) by Response Evaluation Criteria In Solid Tumors 1.0 was applied.ResultsFifty-one patients were enrolled. Confirmed response was recorded in 46 patients. One patient achieved complete response and 33 patients achieved partial response (response rate 34/51 [66.7 %] in the intent-to-treat population). Median follow-up time was 28.6 months, with a median progression-free survival of 9.2 months (95 % confidence interval [CI]: 6.5–11.6) and a median overall survival (OS) of 19.5 months (95 % CI: 15.5–26.0). Patients with a HER2/CEP17 ratio of greater than five achieved improved OS (20.9 vs 19.5 months, p = 0.001). The most common adverse events of grade 3 or above were thrombocytopenia (21.6 %), neutropenia (13.7 %), anemia (5.9 %) and leucopenia (3.9 %).ConclusionThe addition of trastuzumab to oxaliplatin/capecitabine was well tolerated and the results demonstrated encouraging efficacy.Trial registrationClinicalTrials.gov NCT01364493.
BackgroundThe V325 study showed that docetaxel, cisplatin, and fluorouracil (DCF) prolonged overall survival (OS) of patients with advanced gastric cancer, but with a high incidence of dose-limiting toxicities. We investigated the efficacy and safety of a modified DCF (mDCF) regimen for Chinese patients with advanced gastric cancer.MethodsUntreated advanced gastric cancer patients randomly received docetaxel and cisplatin at 60 mg/m2 (day 1) followed by fluorouracil at 600 mg/m2/day (days 1–5; mDCF regimen) or cisplatin at 75 mg/m2 (day 1) followed by fluorouracil at 600 mg/m2/day (days 1–5; CF) every 3 weeks. The primary end point was progression-free survival (PFS). The secondary end points were OS, overall response rate (ORR), time-to-treatment failure (TTF), and safety.ResultsIn total, 243 patients were randomized to treatment (mDCF regimen 121; CF 122). Compared with CF, the mDCF regimen significantly improved PFS and OS: the median PFS was 7.2 and 4.9 months, respectively [hazard ratio (HR) 0.58, log-rank P = 0.0008], and the median OS was 10.2 and 8.5 months, respectively (HR = 0.71, P = 0.0319). Additionally, the mDCF regimen improved the parameters used as secondary objectives: the ORR was 48.7 % with the mDCF regimen versus 33.9 % with CF (P = 0.0244); the median TTF was 3.4 months with the mDCF regimen and 2.4 months with CF (HR = 0.67, P = 0.0027). Grade 3 and grade 4 treatment-related adverse events occurred in 77.3 % of patients who received the mDCF regimen versus 46.1 % of patients who received CF (P < 0.001).ConclusionsThe mDCF regimen, compared with CF, significantly prolonged PFS and OS and enhanced ORR of Chinese patients with advanced gastric cancer. The mDCF regimen achieved efficacy comparable to that of DCF but with fewer toxicities, which is appropriate for the Chinese population.Electronic supplementary materialThe online version of this article (doi:10.1007/s10120-015-0457-4) contains supplementary material, which is available to authorized users.
