Phase I study of sunitinib in combination with gemcitabine and capecitabine for first-line treatment of metastatic or unresectable renal cell carcinoma.

ABSTRACT: The combination of gemcitabine plus capecitabine and sunitinib (GCS) shows activity in metastatic renal cell carcinoma (mRCC). We tested the multitargeted "chemo-switch" regimen as first-line treatment in patients with mRCC.We assessed the maximum tolerated dose and antitumor activity of GCS in treatment-naïve, advanced mRCC patients. Treatment consisted of intravenous gemcitabine on days 1 and 8, oral capecitabine twice daily on days 1-14, and oral sunitinib daily for six 21-day cycles, followed by sunitinib monotherapy at the investigator's discretion. Dose level 0 (DL0) was gemcitabine 1,000 mg/m(2) per day plus capecitabine 650 mg/m(2) per 12 hours plus sunitinib 37.5 mg/day; DL1 was gemcitabine 1,000 mg/m(2) per day plus capecitabine 850 mg/m(2) per 12 hours plus sunitinib 37.5 mg/day.Sixteen patients were enrolled. At DL1, two of four patients had dose-limiting toxicity (DLT; grade 3 diarrhea and grade 4 thrombocytopenia). The dose was reduced to DL0 when only 1 of 12 patients experienced DLT (grade 3 diarrhea, grade 3 mucositis, and grade 3 thrombocytopenia). Dose reductions were frequent (58% of patients), and only seven patients were able to receive the three drugs for more than three cycles. One patient achieved a complete response, three had partial responses, and the best response for four was stable disease.The safety profile of the combination does not seem manageable in this patient population. No further development of the combination is recommended.

Project description:Purpose: Treatment of advanced pancreatic cancer with a single therapeutic at a maximal dose has been largely ineffective at increasing survival. Combination therapies are commonly studied but often limited by toxicity. We previously showed that low-dose multiagent therapy with gemcitabine, docetaxel (taxotere), capecitabine (xeloda), and cisplatin (GTX-C) was safe, well tolerated, and effective (NCT01459614). Here, we hypothesize that adding irinotecan to GTX-C may improve survival with minimal toxicity. Experimental Design: Patients with treatment-naïve metastatic pancreatic adenocarcinoma were treated with gemcitabine, docetaxel (taxotere), capecitabine (xeloda), cisplatin, and irinotecan (GTX-CI). Treatment consisted of capecitabine 500 mg twice daily on days 1–14 and gemcitabine 300 to 500 mg/m2, docetaxel 20 mg/m2, cisplatin 15 to 20 mg/m2, and irinotecan 20 to 60 mg/m2 on days 4 and 11 of a 21-day cycle. The primary objective was 9-month overall survival (OS). Secondary objectives included response rate (RR), disease control rate (DCR), progression-free survival (PFS), and OS. Results: The regimen was well tolerated. The recommended phase II dose was gemcitabine 500 mg/m2, docetaxel 20 mg/m2, capecitabine 500 mg po bid, cisplatin 20 mg/m2, and irinotecan 20 mg/m2. Median follow-up in phase II was 11.02 months (2.37–45.17). Nine-month OS rate was 57% [95% confidence interval (CI): (41–77)]. RR was 57% [95% CI: (37–75) 50% PR and 7% CR]. DCR was 87% [95% CI: (69–96)]. Median OS and PFS were 11.02 [95% CI: (8.54–21.09)] and 8.34 [95% CI: (6.34–NA)] months, respectively. Conclusions: The addition of irinotecan to GTX-C was safe and well tolerated. While the study did not meet its primary objective, the responses were clinically meaningful using a well-tolerated regimen. Significance: We aimed to optimize the previously reported efficacious regimen of low-dose multiagent therapy with GTX-C for the treatment of metastatic pancreatic ductal adenocarcinoma by adding irinotecan. The primary objective was not met, but GTX-CI was well tolerated. The RR of 57%, median PFS of 8.3 months, median OS of 11 months, and 36-month OS rate of 19% suggest clinical benefit. Further optimization of this regimen is warranted.

Project description:BACKGROUND:Anlotinib is a tyrosine kinase inhibitor inhibiting angiogenesis. This multicenter, randomized phase II trial aimed to investigate the efficacy and safety of anlotinib in comparison with sunitinib as first-line treatment for patients with metastatic renal cell carcinoma (mRCC). MATERIALS AND METHODS:Patients with mRCC from 13 clinical centers were randomly assigned in a 2:1 ratio to receive anlotinib (n = 90) or sunitinib (n = 43). Anlotinib was given orally at a dose of 12 mg once daily (2 weeks on/1 week off), and sunitinib was given orally at 50 mg once daily (4 weeks on/2 weeks off). The primary endpoint was progression-free survival (PFS). Secondary endpoints included overall survival (OS), objective response rate (ORR), disease control rate (DCR), and safety. RESULTS:The median PFS was similar with anlotinib and sunitinib (17.5 vs. 16.6 months, p > .05). The median OS (30.9 vs. 30.5 months, p > .05), ORR (30.3% vs. 27.9%), and 6-week DCR (97.8% vs. 93.0%) were similar in the two groups. Adverse events (AEs) of grade 3 or 4 were significantly less frequent with anlotinib than with sunitinib (28.9% vs. 55.8%, p < .01), especially in terms of thrombocytopenia and neutropenia. AEs occurring at a lower frequency with anlotinib were hand-foot syndrome, eyelid edema, hair depigmentation, skin yellowing, neutropenia, thrombocytopenia, and anemia. The incidence of serious AEs was lower with anlotinib than with sunitinib. CONCLUSION:The clinical efficacy of anlotinib was similar to that of sunitinib as the first-line treatment for mRCC, but with a more favorable safety profile. IMPLICATIONS FOR PRACTICE:This study evaluated the efficacy and safety of anlotinib for the first-line treatment of metastatic renal cell carcinoma. Anlotinib, which was developed independently in China, is a new tyrosine kinase inhibitor inhibiting multiple kinases involved in angiogenesis and tumor proliferation. Results indicated that the efficacy of anlotinib is comparable to and the safety is better than that of sunitinib.
