Lugano, Switzerland, 19 September 2020 - The results of the phase 3 CheckMate 9ER trial have provided a new first-line treatment option for patients with metastatic kidney cancer. The late breaking results are presented at ESMO 2020. (1)

The trial took two drugs used as monotherapies in the second line, nivolumab and cabozantinib, and combined them for use as a first-line treatment against standard of care, sunitinib. The combination was superior to sunitinib for progression-free survival, overall survival, and response rate. There was a consistent benefit of the combination over sunitinib in numerous subgroups including age, sex, PD-L1 expression, bone metastases, International Metastatic RCC Database Consortium (IMDC) risk group, and region of the world.

More than 50% of patients in the combination arm needed a dose reduction of cabozantinib due to adverse events. But only 3% had to stop both drugs because of toxicity compared to 9% of patients in the sunitinib arm. The overall rate of serious adverse events was similar between arms, but liver toxicity was more common in the combination arm. As for immune-related side-effects, 19% of patients in the experimental arm needed corticosteroids; just 4% needed corticosteroids for 30 days or longer.

The findings add to mounting evidence showing the advantages of combination therapy over single drugs. Similar to the CheckMate 9ER trial, the KEYNOTE-426 and JAVELIN Renal 101 trials (2,3) combined an immune checkpoint inhibitor with an anti-angiogenic drug, whereas CheckMate 214 combined two immune checkpoint inhibitors. (4)

Study author Dr Toni K. Choueiri, Director, The Lank Center for Genitourinary Oncology, Dana-Farber Cancer Institute and The Jerome and Nancy Kohlberg Chair and Professor of Medicine, Harvard Medical School, Boston, US said: "The results with combination therapy were statistically significant and clinically meaningful. The risk of progression or death was cut by almost 50%, death was cut by 40%, and the response rate doubled. This will become an important treatment option to choose from. The various combination treatments will unlikely be compared head-to-head, but I think quality of life could differentiate this new therapy, as there was a statistical significance favouring the combination arm with both questionnaires we used. (5) Another factor to consider is that clinicians are familiar with both of these drugs."

Commenting on the findings, Dr Dominik Berthold, Head, Specialised Consultation for Urological Cancers Medical Oncology Service, Department of Oncology, Lausanne University Hospital, Switzerland said: "CheckMate 9ER met its efficacy endpoints and the combination can be considered a new first-line treatment option. However, the medical community is divided about whether two immunotherapies or immunotherapy plus an anti-angiogenic drug is the better choice, since the different combinations appear to have similar effectiveness."

He said longer-term data are needed for CheckMate 9ER: "The 18 months of follow-up is still quite short. The question is whether the responses to treatment are durable or patients progress at some point."

"It would also be useful to learn whether the combination of cabozantinib and nivolumab is effective in non-clear cell carcinoma," added Berthold. "This is a minority of patients with advanced kidney cancer which are not well studied and were excluded from this trial."

Berthold noted that when using drugs with specific mechanisms of action, the first-line treatment choice will also determine the selection of second-line therapy. He explained: "If you start with a combination of immune therapy only, it becomes an automatic choice to use an anti-angiogenic drug in the second line. But if you begin with a combination of two mechanisms of action, such as immune therapy and an anti-angiogenic drug, then the second-line choice is less clear. More data are needed on the most suitable order of therapy for the entire population as well as specific groups such as high tumour burden versus slow-growing disease."

Background: Results from the phase 3 CheckMate 9ER trial evaluating the checkpoint inhibitor (CPI) nivolumab (N) plus the tyrosine kinase inhibitor (TKI) cabozantinib (C) v sunitinib (S) for first-line (1L) treatment of advanced clear cell renal cell carcinoma (aRCC) are reported. As monotherapies, N and C have demonstrated efficacy and a manageable safety profile in aRCC. C has immunomodulatory properties that may counteract tumor-induced immunosuppression, providing a rationale for combining N+C.

Methods: Patients (pts) were randomized 1:1 (stratified by IMDC risk score, tumor PD-L1 expression, region) to N 240 mg flat dose IV Q2W + C 40 mg PO QD v S 50 mg PO for 4 wk (6-wk cycles) until disease progression or unacceptable toxicity (max N treatment, 2 y). Primary endpoint: progression-free survival (PFS; alpha = 0.05 final) by blinded independent central review (BICR). Secondary endpoints (hierarchical testing): overall survival (OS; alpha = 0.011 first interim analysis), objective response rate (ORR; alpha = 0.05 final) by BICR, and safety.

Results: A total of 651 pts (22.6% favorable risk, 57.6% intermediate risk, 19.7% poor risk; 24.9% PD-L1 greater-than or equal to 1%) were randomized to N+C (n = 323) v S (n = 328). With 18.1 mo median (10.6 mo minimum) study follow-up, all 3 efficacy endpoints were met. N+C significantly improved PFS (HR 0.51 [95% CI 0.41-0.64], P < 0.0001; median, 16.6 v 8.3 mo) and OS (HR 0.60 [98.89% CI 0.40-0.89]; P = 0.0010; medians not reached) v S, and results were consistent across prespecified IMDC risk and PD-L1 subgroups. ORR (95% CI) was significantly higher with N+C v S (55.7% [50.1-61.2] v 27.1% [22.4-32.3]; P < 0.0001), and 8.0% v 4.6% of pts achieved complete response. Median duration of response was 20.2 v 11.5 mo for N+C v S. Any-grade TRAEs occurred in 96.6% v 93.1% of pts treated with N+C v S (60.6% v 50.9% grade greater-than or equal to 3). One treatment-related death occurred with N+C v 2 with S. TRAEs led to discontinuation of S in 8.8%, N or C in 15.3%, N+C in 3.1%, N only in 5.6%, and C only in 6.6% of pts.

Conclusions: N+C demonstrated superior PFS, OS, and ORR v S in 1L aRCC. The safety profile of this combination was manageable and consistent with the known single-agent AE profiles of N and C. These results support N+C as a new CPI+TKI option for aRCC pts.
