Patients who have advanced renal cell carcinoma (aRCC) with brain metastases may benefit from combination therapy with nivolumab and ipilimumab (NIVO + IPI), new study results presented at the 2019 American Society of Clinical Oncology in Chicago suggest.

The findings are from an interim analysis of CheckMate 920, an ongoing phase 3b/4 clinical trial. Investigators presented findings from 28 patients with previously untreated advanced RCC and asymptomatic brain metastases. Patients received treatment with NIVO 3 mg/kg + IPI 1 mg/kg every 3 weeks for 4 doses, followed by NIVO 480 mg every 4 weeks until disease progression, unacceptable toxicity, or for a maximum of 2 years. The primary end point was high-grade immune-mediated adverse events (IMAEs).

With a minimum follow-up of 6.5 months, grade 3-4 IMAEs observed in 1 or more patients included diarrhea, colitis, diabetic ketoacidosis, immune-mediated hepatitis, hypophysitis, and rash, Hamid Emamekhoo, MD, of the University of Wisconsin School of Medicine in Madison, and colleagues reported in a poster presentation. Median overall survival has not been reached.

The investigators observed no case of treatment-related grade 5 IMAEs.

The cohort had an objective response rate of 28.6%. Median progression-free survival in all treated patients was 9 months.

In their study abstract, Dr Emamekhoo’s team concluded that “NIVO + IPI showed a safety profile consistent with previous reports of this dosing regimen, with encouraging anti-tumor activity.”

The investigators noted that previous clinical trials of patients with aRCC have mostly excluded patients with brain metastases.
