– Tecentriq Hybreza provides patients and physicians with greater flexibility of treatment options while showing safety and efficacy consistent with intravenous (IV) Tecentriq –

– New subcutaneous (SC) option reduces treatment time to approximately 7 minutes, compared with 30-60 minutes for IV infusion –

Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), announced today that the U.S. Food and Drug Administration (FDA) has approved Tecentriq Hybreza™ (atezolizumab and hyaluronidase-tqjs), the first and only PD-(L)1 inhibitor for subcutaneous (SC), under the skin injection for patients in the United States. Tecentriq Hybreza can be injected subcutaneously over approximately seven minutes, compared with 30-60 minutes for standard IV infusion of Tecentriq (atezolizumab). It will be available for all IV indications of Tecentriq approved for adults in the U.S., including certain types of lung, liver, skin and soft tissue cancer.

“By enabling subcutaneous administration for a cancer immunotherapy, Tecentriq Hybreza now offers patients with multiple cancer types and their physicians greater flexibility and choice of treatment administration,” said Levi Garraway, M.D., Ph.D., chief medical officer and head of Global Product Development. “We are pleased to introduce this new subcutaneous formulation that builds on the established safety and efficacy profile of intravenous Tecentriq and can treat patients faster and in more accessible settings.”

“This approval represents a significant option to improve the patient experience,” said Ann Fish-Steagall, RN, senior vice president of Patient Services at the LUNGevity Foundation. “When patients have options, they feel empowered to be vital participants in their own care and choose their preferred treatment option.”

The FDA 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. The Phase II IMscin002 study showed that 71% of patients preferred Tecentriq Hybreza over intravenous atezolizumab, and the most common reasons were less time in the clinic, increased comfort during treatment and reduced emotional distress. 4 out of 5 patients (79%) chose Tecentriq Hybreza to continue their treatment, after experiencing both formulations.

Developing new formulations of our medicines is part of our commitment to improve the patient experience and support people living with different illnesses at every step of their treatment journey. With Tecentriq Hybreza and Roche/Genentech’s 13 other subcutaneous therapies – available across various diseases – we offer additional administration options to meet the diverse preferences of patients.

The subcutaneous formulation of Tecentriq received its first worldwide approval in Great Britain in August 2023 and is now approved in over 50 countries (outside the U.S. marketed as Tecentriq SC). Regulatory reviews in other countries and regions are ongoing.

Genentech is committed to helping people access the medicines they are prescribed and offers comprehensive services for people prescribed Tecentriq Hybreza to help minimize barriers to access and reimbursement. For people who qualify, Genentech offers patient assistance programs through Genentech Access Solutions.

About the IMscin001 study

IMscin001 is a Phase IB/III, global, multicenter, randomized study evaluating the pharmacokinetics, safety and efficacy of Tecentriq Hybreza, compared with IV Tecentriq, 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 C_trough and model-predicted area under the curve. Observed 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 IV Tecentriq. The safety profile of Tecentriq Hybreza was also consistent with that of IV Tecentriq.

About the IMscin002 study

IMscin002 is a Phase II, global crossover study evaluating patient preference between the SC and IV formulations of Tecentriq. The study enrolled 179 patients, including people with PD-L1-positive resected Stage II-IIIB NSCLC who have completed adjuvant platinum-based chemotherapy without evidence of disease recurrence, and untreated patients with PD-L1-high Stage IV NSCLC. The study met its primary endpoint, showing that 71% of participants preferred the SC formulation (21% preferred IV and 8% stated no preference); 79% opted for Tecentriq Hybreza to complete their treatment, after experiencing both formulations of Tecentriq. The study confirmed that switching between Tecentriq Hybreza and IV Tecentriq was well tolerated, with no new safety signals.

About Tecentriq Hybreza

Tecentriq Hybreza combines Tecentriq with Halozyme Therapeutics’ Enhanze^® drug delivery technology.

Tecentriq is a monoclonal antibody designed to bind with a protein called PD-L1. Tecentriq is designed to bind to PD-L1 expressed on tumor cells and tumor-infiltrating immune cells, blocking its interactions with both PD-1 and B7.1 receptors. By inhibiting PD-L1, Tecentriq may enable the re-activation of T cells. Tecentriq may also affect normal cells.

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 is approved for some of the most aggressive and difficult-to-treat forms of cancer. Tecentriq 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 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). In addition to intravenous infusion, Tecentriq has been approved as a subcutaneous formulation in over 50 countries (outside the U.S. marketed as Tecentriq SC). The approved indications for Tecentriq Hybreza and Tecentriq SC mirror those of IV Tecentriq.

What is Tecentriq Hybreza?

Tecentriq Hybreza is a prescription medicine used to treat:

Adults with a type of lung cancer called non-small cell lung cancer (NSCLC).

• Tecentriq Hybreza may be used alone as a treatment for their lung cancer:
  • to help prevent their lung cancer from coming back after their tumor(s) has been removed by surgery and they have received platinum-based chemotherapy, and
  • they have stage 2 to 3A NSCLC (patients should talk to their healthcare provider about what these stages mean), and
  • their cancer tests positive for “PD-L1”.

• Tecentriq Hybreza may be used alone as their first treatment when their lung cancer:
  • has spread or grown, and
  • their cancer tests positive for “high PD-L1”, and
  • their tumor does not have an abnormal “EGFR” or “ALK” gene.

• Tecentriq Hybreza may be used with the medicines bevacizumab, paclitaxel, and carboplatin as their first treatment when their lung cancer:
  • has spread or grown, and
  • is a type called “non-squamous NSCLC,” and
  • their tumor does not have an abnormal “EGFR” or “ALK” gene.

• Tecentriq Hybreza may be used with the medicines paclitaxel protein-bound and carboplatin as their first treatment when their lung cancer:
  • has spread or grown, and
  • is a type called “non-squamous NSCLC,” and
  • their tumor does not have an abnormal “EGFR” or “ALK” gene.

• Tecentriq Hybreza may be used alone when their lung cancer:
  • has spread or grown, and
  • if they have tried chemotherapy that contains platinum, and it did not work or is no longer working.
  • if their tumor has an abnormal “EGFR” or “ALK” gene, they should have also tried an FDA-approved therapy for tumors with these abnormal genes, and it did not work or is no longer working.

Adults with a type of lung cancer called small cell lung cancer (SCLC). Tecentriq Hybreza may be used with the chemotherapy medicines carboplatin and etoposide as their first treatment when their lung cancer:

• is a type called “extensive-stage small cell lung cancer,” which means that it has spread or grown.

Adults with a type of liver cancer called hepatocellular carcinoma (HCC). Tecentriq Hybreza may be used with the medicine bevacizumab when their liver cancer:

• has spread or cannot be removed by surgery, and
• they have not received other medicines by mouth or injection through their vein (IV) to treat their cancer.

Adults with a type of skin cancer called melanoma. Tecentriq Hybreza may be used with the medicines cobimetinib and vemurafenib in patients with melanoma when their skin cancer:

• has spread to other parts of the body or cannot be removed by surgery, and
• has a certain type of abnormal “BRAF” gene. Healthcare providers will perform a test to make sure this Tecentriq Hybreza combination is right for the patient.

Adults with a type of soft tissue tumor (cancer) called alveolar soft part sarcoma (ASPS). Tecentriq Hybreza may be used when their sarcoma:

• has spread to other parts of the body or cannot be removed by surgery.

It is not known if Tecentriq Hybreza is safe and effective in children.
