Roche (SIX: RO, ROG; OTCQX: RHHBY) announced today that the European Commission has granted marketing authorisation for Tecentriq® SC (atezolizumab), the European Union (EU)’s first PD-(L)1 cancer immunotherapy for subcutaneous (under the skin) injection. Last year, more than 38,000 people in the EU received Tecentriq to treat different types of lung, liver, bladder and breast cancer.7 Until now, Tecentriq has been given directly into patients’ veins by IV infusion which takes approximately 30-60 minutes.6 The new subcutaneous injection will cut treatment time to approximately seven minutes, with most injections taking between four and eight minutes.6 The marketing authorisation applies to all approved indications of Tecentriq IV.7

“We are pleased to introduce the first subcutaneous PD-L1 cancer immunotherapy in Europe,” said Levi Garraway, M.D., Ph.D., Roche’s Chief Medical Officer and Head of Global Product Development. “Giving Tecentriq subcutaneously provides more flexibility to patients, while also helping to free up resources in constrained healthcare systems.”

“Ensuring the best possible quality of life is crucial for people living with cancer,” said Dr. Enriqueta Felip, Head of the Thoracic Cancer Unit of Vall d'Hebron Hospital, Spain. “The availability of a subcutaneous cancer immunotherapy option that can minimise the time receiving treatment and even allow for treatment outside of a hospital will undoubtedly make a significant difference to patients and their loved ones.”

The approval is based on pivotal data from the Phase IB/III IMscin001 study, which showed comparable levels of Tecentriq in the blood, when administered subcutaneously, and a safety and efficacy profile consistent with the IV formulation.6,8 90% of healthcare professionals who were surveyed as part of the study agreed that the SC formulation is easy to administer and 75% said it could save time for healthcare teams compared with the IV formulation.6

In addition to offering shorter treatment time, Tecentriq SC may be administered by a healthcare professional outside of the hospital, in a community care setting or at a patient's home, depending on national regulations and health systems. Roche is in discussion with several providers in Europe to include Tecentriq SC in cancer homecare initiatives where possible.

About the IMscin001 study
IMscin001 is a Phase IB/III, global, multicentre, randomised study evaluating the pharmacokinetics, safety and efficacy of Tecentriq SC, compared with Tecentriq IV, in patients with previously treated locally advanced or metastatic non-small cell lung cancer (NSCLC) for whom prior platinum therapy has failed. The study enrolled 371 patients.

The study met its primary endpoints, demonstrating comparable levels of Tecentriq in the blood during a given dosing interval on the basis of established pharmacokinetic measurements; observed serum Ctrough and model-predicted area under the curve. Efficacy, as measured by the overall response rate, progression-free survival, overall survival and duration of response, was similar between the SC and IV treatment arms and consistent with the known profile of Tecentriq IV. The safety profile of Tecentriq SC was also consistent with that of Tecentriq IV.6,8

About Tecentriq SC (subcutaneous)
Tecentriq® (atezolizumab) in Tecentriq SC is the same monoclonal antibody as in Tecentriq IV. It has been designed to bind with a protein called programmed death ligand-1 (PD-L1), which is expressed on tumour cells and tumour-infiltrating immune cells, blocking its interactions with both PD-1 and B7.1 receptors. By inhibiting PD-L1, Tecentriq may enable the activation of T-cells. Tecentriq is a cancer immunotherapy that has the potential to be used across a broad range of cancers.

Tecentriq SC combines Tecentriq with Halozyme Therapeutics’ Enhanze® drug delivery technology. The Enhanze drug delivery technology is based on a proprietary recombinant human hyaluronidase PH20 (rHuPH20), an enzyme that locally and temporarily degrades hyaluronan – a glycosaminoglycan or chain of natural sugars in the body – in the subcutaneous space. This increases the permeability of the tissue under the skin, allowing space for Tecentriq to enter, enabling it to be rapidly dispersed and absorbed into the bloodstream.

Tecentriq SC was first approved in Great Britain in August 2023. The approved indications for Tecentriq SC mirror those of Tecentriq IV. 

The standard IV formulation of Tecentriq is approved for some of the most aggressive and difficult-to-treat forms of cancer. Tecentriq IV was the first cancer immunotherapy approved for the treatment of a certain type of early-stage (adjuvant) NSCLC, small cell lung cancer (SCLC) and hepatocellular carcinoma (HCC). Tecentriq IV is also approved in countries around the world, either alone or in combination with targeted therapies and/or chemotherapies, for various forms of metastatic NSCLC, certain types of metastatic urothelial cancer (mUC), PD-L1-positive metastatic triple-negative breast cancer (TNBC), BRAF V600 mutation-positive advanced melanoma and alveolar soft part sarcoma (ASPS).
