Subcutaneous injection of the immunotherapy nivolumab (model title Opdivo) is noninferior to intravenous supply and dramatically reduces remedy time in sufferers with renal cell carcinoma, as seen within the outcomes of a giant section 3 medical trial reported immediately on the 2024 American Society of Medical Oncology (ASCO) Genitourinary Cancers Symposium in San Francisco, California. Saby George, MD, FACP, Professor of Oncology and Medication and Director of Community Medical Trials at Roswell Park Complete Most cancers Middle, will ship an oral summary summarizing the findings of “A Research of Subcutaneous Nivolumab Versus Intravenous Nivolumab in Contributors with Beforehand Handled Clear Cell Renal Carcinoma That Is Superior or Has Unfold (CheckMate-67T)” (NCT04810078).
“The burden of remedy felt by most cancers sufferers is great. If nivolumab will be given as a subcutaneous injection as an alternative of an intravenous infusion, their remedy expertise shall be considerably improved,” says Dr. George, who’s the presenting creator, a member of the medical trial steering committee and web site principal investigator at Roswell Park. “As a substitute of 1 hour in an infusion chair, they are going to get the injection executed in 5 minutes.”
He factors to the excessive demand for infusion chair appointments at most most cancers facilities, which can lead to remedy delays of every week or extra.
If nivolumab turns into accessible subcutaneously, we are able to administer it within the clinic as an alternative of sending sufferers to infusion facilities.”

That end result might concurrently pace remedy time for sufferers receiving nivolumab and shorten wait instances for sufferers who nonetheless must obtain remedy in an infusion heart.
The provision of injectable nivolumab might additionally cut back well being disparities. “One of many main issues is entry to remedy,” says Dr. George, noting that some sufferers stay a protracted distance from an infusion heart and wouldn’t have a approach to get there. “Sufferers who do not stay close to an infusion heart might get remedy nearer to house, at a clinic, and that might enhance entry and assist cut back disparities.”
Sponsored by Bristol Myers Squibb, the drug’s producer, the medical trial started in Might 2021, randomizing 495 sufferers at 73 facilities in 17 international locations. Roswell Park was one in every of solely three collaborating websites within the U.S. and the one one in New York State.
Sufferers within the research had superior or metastatic renal cell carcinoma, had obtained not more than two prior therapies with systemic therapies and no prior immunotherapy. They had been randomized 1:1 to obtain nivolumab both subcutaneously or intravenously. Nivolumab is FDA-approved and the standard-of-care remedy for these sufferers.
The research’s main goal was to guage the pharmacokinetics of subcutaneous vs. intravenous supply -; how the physique interacted with the nivolumab, together with whether or not blood ranges of the drug had been comparable within the two teams over time. These measures included the every day common focus of the drug within the blood over 28 days (Cavgd28) and the focus of the drug on the finish of the dosing cycle (Cminss). Each measures had been noninferior to intravenous nivolumab, as evidenced in pharmacokinetic measures and total response charge.
The target response charge for the subcutaneous group -; the share of sufferers who achieved an entire or partial response, measured by blinded unbiased central evaluate -; proved noninferior to the intravenous group, at 24.2% vs. 18.2%, respectively. Median progression-free survival stood at 7.23 months for the subcutaneous group vs. 5.65 months for the IV group. The protection profile was comparable for each teams.
Greater than 80,000 new circumstances of renal cell carcinoma are recognized within the U.S. every year.
As a result of nivolumab is already FDA-approved for greater than 20 indications throughout a number of malignancies, CheckMate-67T will possible function a gateway to further research evaluating the effectiveness of the subcutaneous system in different affected person populations.
“This can be a groundbreaking achievement for sufferers and physicians, and will certainly make remedy simpler for sufferers,” says Dr. George.
