Abstract

Background

Lenvatinib in combination with pembrolizumab or everolimus has activity against advanced renal cell carcinoma. The efficacy of these regimens as compared with that of sunitinib is unclear.

Methods

In this phase 3 trial, we randomly assigned (in a 1:1:1 ratio) patients with advanced renal cell carcinoma and no previous systemic therapy to receive lenvatinib (20 mg orally once daily) plus pembrolizumab (200 mg intravenously once every 3 weeks), lenvatinib (18 mg orally once daily) plus everolimus (5 mg orally once daily), or sunitinib (50 mg orally once daily, alternating 4 weeks receiving treatment and 2 weeks without treatment). The primary end point was progression-free survival, as assessed by an independent review committee in accordance with Response Evaluation Criteria in Solid Tumors, version 1.1. Overall survival and safety were also evaluated.

Results

A total of 1069 patients were randomly assigned to receive lenvatinib plus pembrolizumab (355 patients), lenvatinib plus everolimus (357), or sunitinib (357). Progression-free survival was longer with lenvatinib plus pembrolizumab than with sunitinib (median, 23.9 vs. 9.2 months; hazard ratio for disease progression or death, 0.39; 95% confidence interval [CI], 0.32 to 0.49; P<0.001) and was longer with lenvatinib plus everolimus than with sunitinib (median, 14.7 vs. 9.2 months; hazard ratio, 0.65; 95% CI, 0.53 to 0.80; P<0.001). Overall survival was longer with lenvatinib plus pembrolizumab than with sunitinib (hazard ratio for death, 0.66; 95% CI, 0.49 to 0.88; P = 0.005) but was not longer with lenvatinib plus everolimus than with sunitinib (hazard ratio, 1.15; 95% CI, 0.88 to 1.50; P = 0.30). Grade 3 or higher adverse events emerged or worsened during treatment in 82.4% of the patients who received lenvatinib plus pembrolizumab, 83.1% of those who received lenvatinib plus everolimus, and 71.8% of those who received sunitinib. Grade 3 or higher adverse events occurring in at least 10% of the patients in any group included hypertension, diarrhea, and elevated lipase levels.

Conclusions

Lenvatinib plus pembrolizumab was associated with significantly longer progression-free survival and overall survival than sunitinib. (Funded by Eisai and Merck Sharp and Dohme; CLEAR ClinicalTrials.gov number, NCT02811861.).

Yes, high risk of both hypertension and diarrhea. The diarrhea can be very difficult to manage. The lenvatinib definitely adds a level of complexity to the management of pembro side effects. This requires dose reductions and interruptions, maybe even hospitalization for dehydration/renal insufficien...

I think treatment selection after recurrence/metastases will depend on the timing after adjuvant pembrolizumab has been completed. If it's about 9 months or more, I think re-challenge with pure IO/IO combination is fair, especially if a patient tolerated pembrolizumab well. If it's within 3-6 months...

I do think about nivo/ipi for a subset of patients with favorable risk disease -- usually younger patients who are shooting for a complete response. In the favorable risk subset of patients in CheckMate 214, the complete responses are higher than even in the intermediate-poor risk. Patients who have...

Certainly overall survival is the ultimate endpoint, but I would not discount PFS and complete responses (CRs do drive survival benefit in a small subset of patients as evidenced by high dose IL-2). Currently we have no data comparing IO/IO vs IO/TKI combinations head to head, so we generally select...

Toxicity profile is very important in choosing a regimen, noting that no direct comparisons exist. Ipi/nivo is characterized by more initial, inflammatory toxicity, but relatively well tolerated nivo monotherapy maintenance and the ability to be off all therapy for a subset of patients. IO/TKI combo...

Patients with progression after IO-based therapies are increasingly common. Standard options include single agent TKI (cabozantinib most commonly used after axi/pembro) and lenvatinib/everolimus. The role of additional IO-based therapy in this setting is unproven, although there are data with lenvat...

Any TKI will potentially increase the risk of thrombosis, so this is a bit of a challenge for the patient. However, cabozantinib, based on personal experience, is more likely to cause this complication and other TKIs may be better in this regard. If you need to completely avoid TKIs, everolimus mono...

The role and timing of debulking nephrectomy in mRCC has been evolving over the last several years. This is in part due to CARMENA, which in my opinion reinforced that patient selection is critical, and in part due to increased activity of systemic therapy. I think patients with limited IMDC risk fa...
