Subcutaneous nivolumab (nivolumab and hyaluronidase) shows noninferiority compared to intravenous Opdivo (nivolumab) in advanced or metastatic clear cell renal cell carcinoma in CheckMate

In addition, subcutaneous nivolumab displayed noninferior objective response rate (ORR) as assessed by Blinded Independent Central Review (BICR) vs. IV Opdivo. These results were featured in a late-breaking oral presentation (Abstract #LBA360) at the American Society of Clinical Oncology (ASCO) 2024 Genitourinary Cancers Symposium from January 25-27, 2024.

The data from CheckMate -67T with the subcutaneous formulation of nivolumab co-formulated with recombinant human hyaluronidase represent a groundbreaking advancement in oncology research for physicians and our patients,” said Saby George, M.D., F.A.C.P., professor of Oncology and Medicine, director of Network Clinical Trials, Department of Medicine, Roswell Park Comprehensive Cancer Center. “Having the option to administer immunotherapy subcutaneously could undoubtedly reduce the treatment burden that patients diagnosed with cancer currently face, as well as help maximize efficiencies within healthcare systems. As it stands, intravenous immunotherapy infusion can take precious time, which we know is an important commodity for patients and the doctors who treat them. That’s why these results indicating noninferiority with subcutaneous nivolumab have the potential to be practice-changing and to improve patients’ treatment experience with one injection that can be given in under five minutes and, in some cases, outside of the infusion center.”

In the CheckMate -67T trial investigating subcutaneous nivolumab (n=248) vs. IV Opdivo (n=247) in patients with advanced of metastatic ccRCC : i. Cavgd28: Noninferiority of subcutaneous nivolumab to IV Opdivo was shown for the time-averaged serum concentration over the first 28 days, with a geometric mean ratio of 2.098 (90% Confidence Interval [CI]: 2.001 - 2.200). ii. Cminss: Noninferiority of subcutaneous nivolumab to IV Opdivo was shown for the minimum serum concentration at steady state, with a geometric mean ratio of 1.774 (90% CI: 1.633 - 1.927). iii. ORR: Noninferiority was also seen in the key powered secondary endpoint of ORR by BICR, with subcutaneous nivolumab demonstrating an ORR of 24.2% vs. 18.2% with IV Opdivo (Relative Risk Ratio [RR] 1.33; 95% CI: 0.94 to 1.87). iv. PFS: Median PFS by BICR with subcutaneous nivolumab was 7.23 months and 5.65 months with IV Opdivo.

Safety : The safety profile of subcutaneous nivolumab was consistent with the IV formulation. Incidence of local injection site reactions with subcutaneous nivolumab was 8.1%. Additionally, reactions were low grade and transient. Among patients treated with subcutaneous nivolumab (n=247), grade 3-4 adverse events (AEs) occurred in 35.2% of patients vs. 40.8% of patients treated with IV Opdivo (n=245). Treatment-related AEs occurred in 9.7% vs. 14.7% of patients, serious AEs in 21.1% vs. 22.9% of patients and treatment-related serious AEs in 6.5% of patients for both the subcutaneous and IV formulations.

“These results from the CheckMate -67T trial build on our deep scientific expertise in the use of immunotherapy in solid tumor oncology and our commitment to finding ways to help improve quality of life for patients,” said Gina Fusaro, Ph.D., vice president, global program lead, Bristol Myers Squibb. “We are thrilled to present this research for the first time evaluating subcutaneous nivolumab, demonstrating noninferiority compared to intravenous Opdivo and supporting subcutaneous nivolumab as a potential new option to improve healthcare efficiency. Convenience is an important benefit of subcutaneous immunotherapy and we are excited about the potential for this treatment to reduce patient burden and provide greater flexibility to patients and health care providers. We look forward to discussing next steps for subcutaneous nivolumab across multiple tumor types with health authorities.”
