New PD-1 Inhibitor Offers Faster Administration for Cancer Patients

Bristol Myers Squibb has announced a significant advancement in cancer treatment with the U.S. Food and Drug Administration’s approval of Opdivo Qvantig™ (nivolumab and hyaluronidase-nvhy) for subcutaneous use. This innovative formulation combines nivolumab with recombinant human hyaluronidase (rHuPH20), offering a new administration route for adult patients with solid tumors across most previously approved Opdivo indications.

The approval stems from the Phase 3 CheckMate-67T trial, which demonstrated that Opdivo Qvantig achieves non-inferior pharmacokinetic exposures and similar efficacy in overall response rate compared to intravenous (IV) Opdivo, while maintaining a comparable safety profile.

Dr. Saby George, a medical oncologist at Roswell Park Comprehensive Cancer Center, highlighted the patient-centric nature of this development. He noted that Opdivo Qvantig delivers consistent efficacy and comparable safety to IV nivolumab, but with the added benefit of faster administration – typically three to five minutes.

The trial results were compelling. The geometric mean ratios for time-averaged concentration over 28 days (Cavgd28) and minimum concentration at steady state (Cminss) of Opdivo Qvantig vs. IV Opdivo were 2.10 and 1.77, respectively. The overall response rate was 24% for Opdivo Qvantig compared to 18% for IV Opdivo, confirming similar efficacy.

This subcutaneous formulation offers increased flexibility for patients and healthcare providers. It may allow for treatment administration in diverse settings, potentially reducing preparation steps and administration time. In the trial, most patients received their doses without interruptions or delays, with an average administration time of about five minutes.

Opdivo Qvantig now stands as the first and only subcutaneously administered PD-1 inhibitor, offering a significant reduction in administration time from 30 minutes for IV Opdivo to just 3-5 minutes.

However, healthcare professionals and patients should be aware of the associated warnings and precautions. These include potential severe and fatal immune-mediated adverse reactions, complications from allogeneic hematopoietic stem cell transplantation, embryo-fetal toxicity, and increased mortality risk in multiple myeloma patients when combined with certain other treatments.

Adam Lenkowsky, executive vice president at Bristol Myers Squibb, emphasized the company’s commitment to improving patients’ healthcare journeys. He expressed enthusiasm about offering cancer patients a faster delivery method for this established immunotherapy option.

Audrey Davis from the Cancer Support Community underscored the importance of flexible treatment options for cancer patients. She welcomed this advancement in immunotherapy administration as a potential aid for patients and caregivers navigating the challenges of cancer treatment.

Commentary by SuppBase columnist Alice Winters:

The approval of Opdivo Qvantig marks a significant milestone in the evolution of cancer immunotherapy. As a health product commentator, I find several aspects of this development particularly noteworthy.

First, the formulation itself deserves attention. The combination of nivolumab with hyaluronidase is a clever approach to enable subcutaneous administration. Hyaluronidase temporarily degrades hyaluronic acid in the extracellular matrix, facilitating the dispersion and absorption of co-administered drugs. This formulation strategy not only allows for a new route of administration but also maintains the pharmacokinetic profile necessary for efficacy.

The reduction in administration time from 30 minutes to 3-5 minutes is substantial. In the context of cancer treatment, where patients often face long hours in clinical settings, this time savings could significantly improve quality of life. It may reduce the psychological burden associated with lengthy hospital visits and potentially increase adherence to treatment schedules.

Moreover, the flexibility in administration settings could be transformative for rural or mobility-challenged patients. The ability to receive treatment closer to home or in community-based settings could dramatically reduce the travel burden often associated with cancer care.

However, it’s crucial to note that this convenience does not come at the cost of efficacy or safety. The non-inferior pharmacokinetics and comparable overall response rates are reassuring, suggesting that patients are not compromising on treatment quality for the sake of convenience.

The safety profile, particularly the immune-mediated adverse reactions, remains a critical consideration. While the subcutaneous formulation doesn’t appear to alter the safety profile significantly, the potent immunomodulatory effects of PD-1 inhibitors like nivolumab still require careful monitoring and management.

From a market perspective, Opdivo Qvantig positions Bristol Myers Squibb at the forefront of patient-centric drug delivery in immuno-oncology. As the first subcutaneous PD-1 inhibitor, it may set a new standard in the field, potentially influencing future drug development and delivery strategies.

In conclusion, Opdivo Qvantig represents a noteworthy advancement in cancer immunotherapy administration. It exemplifies the industry’s shift towards more patient-friendly treatment options without compromising on efficacy. As we move forward, it will be interesting to observe how this development influences patient preferences, treatment protocols, and potentially, outcomes in real-world settings. While it’s not a revolution in the mechanism of action, it’s certainly an evolution in how we deliver these crucial therapies to patients in need.
