Combining immune checkpoint inhibition plus tyrosine kinase inhibition as first and subsequent treatments for metastatic renal cell carcinoma.

ABSTRACT:

Background

Immune checkpoint inhibitor/tyrosine kinase inhibitor (ICI/TKI) combinations are a new standard of care for the initial treatment of metastatic renal cell carcinoma (mRCC). Their efficacy and toxicity beyond the first-line setting remain poorly defined.

Methods

We retrospectively reviewed charts for 85 adults with mRCC of any histology receiving combination of ICI/TKI in any line of treatment at two academic centers as of 05/01/2020. We collected clinical, pathological, and treatment-related variables. Outcomes including objective response rate (ORR), progression-free survival (PFS), and toxicity were analyzed via descriptive statistics and the Kaplan-Meier method.

Results

Patients received pembrolizumab, nivolumab, avelumab, or nivolumab-ipilimumab, with concurrent use of sunitinib, axitinib, pazopanib, lenvatinib, or cabozantinib. Thirty-three patients received first-line ICI/TKI therapy, while 52 received ≥ second-line ICI/TKI. The efficacy of ICI/TKI therapy decreased with increasing lines of treatment (ORR: 56.7%, 37.5%, 21.4%, and 21%; median PFS [mPFS]: 15.2, 14.2, 10.1, and 6.8 months, for first, second, third, and ≥ fourth line therapy, respectively). In the ≥ second-line setting, ICI/TKI was most useful in patients who received ICI only, with an ORR of 50% and a mPFS of 9.1 months. Efficacy was limited in patients who received both TKI and ICI previously, with an ORR of 20% and a mPFS of 5.5 months. Overall, ≥ second-line ICI/TKI was tolerable with 25 of 52 (52%) patients developing grade ≥3 adverse events.

Conclusions

ICI/TKI combination therapy is feasible and safe beyond the first-line setting. Prior treatment history appears to impact efficacy but has a lesser effect on safety/tolerability.

Project description:BackgroundImmune checkpoint inhibitors and vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitors are the most commonly used medications in metastatic renal cell carcinoma (mRCC). Recently, large clinical trials have shown favorable outcomes in patients treated with combined immune checkpoint plus VEGFR inhibition compared with VEGFR inhibition alone. However, the benefit among favorable risk (based on International Metastatic Renal Cell Carcinoma Database Consortium score) and elderly (age > 65 years) patients was not clear, leading to a discrepancy between United States Food and Drug Administration and European Association of Urology recommendations.Materials and methodsWe searched available literature for phase III randomized clinical trials evaluating the efficacy of combining immunotherapy plus VEGF/VEGFR inhibitors versus standard of care in patients with previously untreated mRCC. Combinations that were included in United States Food and Drug Administration recommendations or European Association of Urology guidelines were used for analysis. We performed a meta-analysis with a random effects model to evaluate the efficacy of immunotherapy-VEGFR inhibitor combinations compared with sunitinib in favorable risk and elderly patients.ResultsOur analysis demonstrated that progression-free survival (PFS) was significantly prolonged with combination therapy compared with sunitinib in patients with age > 65 years (hazard ratio, 0.66; 95% confidence interval, 0.52-0.84; P = .001). The PFS in favorable risk disease was improved with combination therapy compared with sunitinib, but the difference was not statistically significant (hazard ratio, 0.68; 95% confidence interval, 0.46-1.01; P = .055).ConclusionOur meta-analysis strengthens the trend of beneficial effect in prolonging PFS in both subgroups compared with each trial alone, indicating that favorable risk and elderly patients with mRCC likely benefit from combining programmed cell death 1 or programmed cell death-ligand 1 and VEGFR inhibition.
