Outcomes of axitinib versus sunitinib as first-line therapy to patients with metastatic renal cell carcinoma in the immune-oncology era.

ABSTRACT: Although combination immune checkpoint inhibitor (immuno-oncology [IO]) therapy is the first-line treatment for metastatic renal cell carcinoma (mRCC), it mostly causes resistance and tumor regrowth. Therefore, an optimal second-line therapy is necessary. Such therapy typically comprises vascular endothelial growth factor receptor-tyrosine kinase inhibitors (VEGFR-TKIs). This study was aimed at comparing the efficacy of two TKIs-axitinib and sunitinib-in mRCC patients. From January 2008 to October 2018, we registered 703 mRCC patients from 8 Japanese institutes. Of these, 408 patients received axitinib or sunitinib as the first-line treatment. Thereafter, efficacy and survival rate were compared between the axitinib and sunitinib groups. To reduce the effects of selection bias and potential confounders, propensity score matching analysis was performed. Axitinib and sunitinib were administered in 274 and 134 patients, respectively. More than 25% of the patients received nivolumab sequence therapy. To calculate the propensity scores for each patient, we performed multivariate logistic regression analysis. The objective response rate, progression-free survival (PFS), cause-specific survival, and overall survival (OS) were significantly better in the axitinib group than in the sunitinib group. Furthermore, the OS was better in the nivolumab-treated patients in the axitinib group. Axitinib showed higher efficacy and afforded greater survival benefits than did sunitinib when administered as first-line therapy in mRCC patients. Thus, from among VEGFR-TKIs, axitinib might be a possible option for application in the middle of IO drug-based treatment sequences.

Project description:BackgroundThe data from the phase III clinical trial KEYNOTE-426 indicated that pembrolizumab plus axitinib compared with sunitinib could generate clinical benefits in patients with previously untreated advanced renal cell carcinoma (RCC). Given the incremental clinical benefits, we examined the potential cost-effectiveness of pembrolizumab plus axitinib versus sunitinib in the first-line setting for patients with advanced RCC from the U.S. payers' perspective.Materials and methodsCost and health outcomes were estimated at a willingness-to-pay (WTP) threshold of $100,000 to $150,000 per quality-adjusted life-year (QALY). One-way and probabilistic sensitivity analyses were performed by varying potentially modifiable parameters, and additional subgroup analyses were performed as well.ResultsUpon our analyses, the total treatment costs in the pembrolizumab plus axitinib and sunitinib groups were $522,796 and $348,424 and the QALYs gained 2.90 and 1.72, respectively. In the base-case analysis, compared with receiving sunitinib, patients with advanced RCC receiving pembrolizumab plus axitinib gained 1.18 more QALYs at an incremental cost-effectiveness ratio of $148,676/QALY. The results of subgroup analyses demonstrated that pembrolizumab plus axitinib was most cost-effective for patients who had one organ with metastasis.ConclusionFirst-line treatment with pembrolizumab plus axitinib, compared with sunitinib, is a cost-effective strategy when the value of WTP is from $100,000 to $150,000 per QALY in patients with advanced RCC. For patients with one-organ metastasis and those in International Metastatic Renal Cell Carcinoma Database Consortium poor risk group, first-line treatment with pembrolizumab plus axitinib is more cost-effective than others.Implications for practiceThis was the first study to examine the cost-effectiveness of pembrolizumab plus axitinib versus sunitinib in advanced renal cell carcinoma (RCC). This study found that first-line treatment with pembrolizumab plus axitinib is a cost-effective strategy when the value of willingness-to-pay is from $100,000 to $150,000 per quality-adjusted life-year in patients with advanced RCC from the U.S. payers' perspective.

Project description:BackgroundIn a single-group, phase 1b trial, avelumab plus axitinib resulted in objective responses in patients with advanced renal-cell carcinoma. This phase 3 trial involving previously untreated patients with advanced renal-cell carcinoma compared avelumab plus axitinib with the standard-of-care sunitinib.MethodsWe randomly assigned patients in a 1:1 ratio to receive avelumab (10 mg per kilogram of body weight) intravenously every 2 weeks plus axitinib (5 mg) orally twice daily or sunitinib (50 mg) orally once daily for 4 weeks (6-week cycle). The two independent primary end points were progression-free survival and overall survival among patients with programmed death ligand 1 (PD-L1)-positive tumors. A key secondary end point was progression-free survival in the overall population; other end points included objective response and safety.ResultsA total of 886 patients were assigned to receive avelumab plus axitinib (442 patients) or sunitinib (444 patients). Among the 560 patients with PD-L1-positive tumors (63.2%), the median progression-free survival was 13.8 months with avelumab plus axitinib, as compared with 7.2 months with sunitinib (hazard ratio for disease progression or death, 0.61; 95% confidence interval [CI], 0.47 to 0.79; P<0.001); in the overall population, the median progression-free survival was 13.8 months, as compared with 8.4 months (hazard ratio, 0.69; 95% CI, 0.56 to 0.84; P<0.001). Among the patients with PD-L1-positive tumors, the objective response rate was 55.2% with avelumab plus axitinib and 25.5% with sunitinib; at a median follow-up for overall survival of 11.6 months and 10.7 months in the two groups, 37 patients and 44 patients had died, respectively. Adverse events during treatment occurred in 99.5% of patients in the avelumab-plus-axitinib group and in 99.3% of patients in the sunitinib group; these events were grade 3 or higher in 71.2% and 71.5% of the patients in the respective groups.ConclusionsProgression-free survival was significantly longer with avelumab plus axitinib than with sunitinib among patients who received these agents as first-line treatment for advanced renal-cell carcinoma.

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.
