One of the most meaningful shifts in the cancer treatment landscape has been the move toward therapies that not only fight the disease, but also empower patients and healthcare professionals (HCPs) with choices on how they receive and provide care. Subcutaneous (SC) cancer immunotherapies are at the forefront of this shift, providing new treatment options that can reduce administration time and offer patients and HCPs more choice.

The recent FDA approval of Tecentriq Hybreza^TM (atezolizumab and hyaluronidase-tqjs), the first anti-PD-(L)1 inhibitor available via SC injection, offers HCPs a practical and patient-centric alternative to traditional intravenous (IV) administration.¹ Jorge Nieva, MD, Associate Professor of Clinical Medicine, USC Norris Comprehensive Cancer Center, discusses how this novel formulation can expand access to cancer care without compromising efficacy or safety.

Why Subcutaneous Delivery Matters in Oncology

SC formulations are increasingly important, particularly in oncology, where treatment regimens can be time-intensive and physically demanding. Unlike IV infusions that often require longer visits, SC injections may offer a convenient alternative given they are administered more quickly, allowing patients the potential to spend less time in the clinic.¹

Dr. Nieva notes, "A large advantage to subcutaneous delivery is time. These technologies can be readily delivered in minutes and don't require the same treatment time required for standard IV infusion. They can often be done quickly for patients and get them in and out of the office."

SC formulations may also help reduce costs for hospitals and clinics, allowing for more flexible appointment scheduling, increasing the availability of infusion chairs, and reducing workload for HCPs.²

Tecentriq Hybreza: Leading the Way in Innovative Immunotherapy

Tecentriq Hybreza is the first and only FDA approved PD-(L)1 cancer immunotherapy with IV and SC formulation. This novel formulation is authorized for all adult indications previously reserved for the IV version of Tecentriq, targeting select types of lung, liver, skin, and soft tissue cancers.

The FDA approval is backed by clinical data that demonstrates Tecentriq Hybreza achieves comparable atezolizumab blood concentration levels, with safety and efficacy outcomes observed to be consistent with the traditional IV formulation.¹

Dr. Nieva highlights this advantage: "It's not about giving patients a new drug or changing their treatment, but rather providing them with options."

As oncology continues to evolve towards more patient-centered care, SC immunotherapies like Tecentriq Hybreza will play a crucial role in improving treatment efficiency and the overall patient experience.

One of the most compelling aspects of Tecentriq Hybreza is the improved patient experience data it offers. The IMscin002 Phase II patient preference study found that seven out of ten patients preferred Tecentriq Hybreza over Tecentriq IV after experiencing both, citing reduced time in the clinic (64%).¹ The study also confirmed that switching between Tecentriq Hybreza and IV Tecentriq was well tolerated. This preference data highlights the potential for improved adherence and satisfaction with treatment, factors that are increasingly important in oncology care.

Dr. Nieva notes, "Given that we have comparable pharmacokinetic data with the subcutaneous formulation, we need to think about the patient's life beyond the initial storm of fear and anxiety that happens at diagnosis. We have to start empowering patients and providing treatment options that prioritize each patient's treatment goals."

Looking Ahead: The Role of Tecentriq Hybreza in Cancer Care

Tecentriq Hybreza adds another option to the Genentech Oncology portfolio, which provides a variety of administration options to meet the diverse preferences of patients. The introduction of Tecentriq Hybreza is also part of Genentech's broader strategy to develop therapies that not only improve patient outcomes but offer them a choice in their treatment plan.

This shift towards more patient-centric treatment options signals a new era in oncology, one that empowers HCPs to provide high-quality care that aligns with the evolving needs of their patients. As Dr. Nieva aptly puts it, "It's always great when new medicines come out and empower patients to have more choice."

Warnings and Precautions

Severe and Fatal Immune-Mediated Adverse Reactions

TECENTRIQ HYBREZA is a monoclonal antibody that belongs to a class of drugs that bind to either the programmed death-receptor 1 (PD-1) or the PD-ligand 1 (PD-L1), blocking the PD-1/PD-L1 pathway, thereby removing inhibition of the immune response, potentially breaking peripheral tolerance and inducing immune-mediated adverse reactions. The following immune-mediated adverse reactions may not include all possible severe and fatal immune-mediated reactions.

Immune-mediated adverse reactions can occur in any organ system or tissue and at any time after starting TECENTRIQ HYBREZA. While immune-mediated adverse reactions usually manifest during treatment with TECENTRIQ HYBREZA, they can also manifest after discontinuation of treatment. Early identification and management of immune-mediated adverse reactions are essential to ensure safe use of TECENTRIQ HYBREZA.

Monitor patients closely for symptoms and signs that may be clinical manifestations of underlying immune-mediated adverse reactions. Evaluate liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment. In cases of suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate.

Withhold or permanently discontinue TECENTRIQ HYBREZA depending on severity. In general, if TECENTRIQ HYBREZA requires interruption or discontinuation, administer systemic corticosteroid therapy (1 to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less, then initiate corticosteroid taper and continue to taper over at least 1 month. Consider administration of other systemic immunosuppressants in patients whose immune-mediated adverse reactions are not controlled with corticosteroid therapy.
