Angiogenic and immunomodulatory biomarkers in axitinib-treated patients with advanced renal cell carcinoma.

ABSTRACT: Aim: Immunomodulatory mechanisms contributing to angiogenic inhibition in renal tumors are not well characterized. We report associations between efficacy and tumor-associated immune cells and mRNA/miRNA expression in patients from AXIS. Materials & methods: Immunohistochemistry (n = 52) and mRNA/miRNA expression analyses (n = 72) were performed on tumor samples. Results: In axitinib-treated patients, higher CXCR4 and TLR3 expression, respectively, was associated with longer progression-free survival (hazard ratio; 95% CI: 0.3; 0.1-0.8 and 0.4; 0.2-0.9) and showed interaction with treatment (p = 0.029 and p < 0.001); lower CCR7 expression was associated with objective response (odds ratio: 0.1; 95% CI: 0.01-1.0) and longer overall survival (hazard ratio: 3.9; 95% CI: 1.4-10.3). Conclusion: CCR7, CXCR4 and TLR3 expression levels may be prognostic/predictive of clinical benefit with axitinib. Clinical trial identifier: ClinicalTrials.gov NCT00678392.

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:BackgroundPrevious studies have shown a modest impact of tyrosine kinase inhibitors on primary renal tumors. Those studies were mostly retrospective or heterogeneous in their eligibility criteria with regard to histology, disease stage, duration of therapy, and time off therapy prior to surgery.ObjectiveTo prospectively investigate the safety and efficacy of axitinib in downsizing tumors in patients with nonmetastatic biopsy-proven clear cell renal cell carcinoma (ccRCC).Design, setting, and participantsThis was a single-institution, single-arm phase 2 clinical trial. Patients with locally advanced nonmetastatic biopsy-proven ccRCC were eligible.InterventionPatients received axitinib 5mg for up to 12 wk. Axitinib was continued until 36h prior to surgery. Patients underwent partial or radical nephrectomy after axitinib therapy.Outcome measurements and statistical analysisThe primary outcome was objective response rate prior to surgery. Secondary outcomes included safety, tolerability, and quality of life. A dedicated radiologist independently reviewed all computed tomography scans to evaluate for response using Response Evaluation Criteria in Solid Tumors (RECIST).Results and limitationsA total of 24 patients were treated. Twenty-two patients continued axitinib for 12 wk; 1 patient continued axitinib for 11 wk and underwent surgery as planned. One patient stopped treatment at 7 wk due to adverse events (AEs). Median reduction of primary renal tumor diameter was 28.3%. Eleven patients experienced a partial response per RECIST; 13 had stable disease. There was no progression of disease while on axitinib. The most common AEs were hypertension, fatigue, oral mucositis, hypothyroidism, and hand-foot syndrome. Postoperatively, 2 grade 3 and 13 grade 2 complications were noted. No grade 4 or 5 complications occurred. Functional Assessment of Cancer Therapy-Kidney Specific Index-15 changed over time, with quality of life worsening while on therapy, but by week 19, it was not statistically different from screening. Limitations include single-arm design and small patient numbers.ConclusionsAxitinib was clinically active and reasonably well tolerated in the neoadjuvant setting in patients with locally advanced nonmetastatic ccRCC.Patient summaryIn this prospective clinical trial, we found that axitinib, when given prior to surgery, results in significant shrinking of kidney cancers. Larger studies are needed prior to further clinical use.Trial registrationThis clinical trial was registered with clinicaltrials.gov (NCT01263769).
