Phase 3 Study Of Subcutaneous Pertuzumab And Trastuzumab Initiated Using Halozyme's ENHANZE® Technology

PR Newswire

SAN DIEGO, July 26, 2018 /PRNewswire/ -- Halozyme Therapeutics, Inc. (NASDAQ:HALO), a biotechnology company developing novel oncology and drug-delivery therapies, today announced that Genentech, a member of the Roche Group, has dosed the first patient in a Phase 3 study of a fixed-dose combination of pertuzumab (Perjeta®) and trastuzumab (Herceptin®) for subcutaneous administration using Halozyme's proprietary ENHANZE® drug-delivery technology in combination with chemotherapy.

The global Phase 3 study is investigating the combination as a single fixed-dose in patients with human epidermal growth factor receptor 2 (HER2)-positive early breast cancer in the neoadjuvant and adjuvant settings. The estimated administration time for the initial loading dose of the combination is 7 to 8 minutes and subsequent maintenance doses are approximately 5 minutes.

"We are excited to support the initiation by Genentech of the first Phase 3 study exploring a fixed-dose combination of two therapeutics," said Dr. Helen Torley, president and CEO of Halozyme. "For breast cancer patients and healthcare professionals, the approach of administering pertuzumab and trastuzumab subcutaneously in a single injection with ENHANZE offers the potential for a new treatment administration option."

The Phase 3 study follows a Phase 1b clinical trial that assessed the safety, tolerability and pharmacokinetics of the same fixed-dose combination presented at the 2017 San Antonio Breast Cancer Symposium.

Perjeta (pertuzumab) and Herceptin (trastuzumab) are registered trademarks of Genentech, a member of the Roche Group.

About ENHANZE Technology
Halozyme's proprietary ENHANZE drug-delivery technology is based on its patented recombinant human hyaluronidase enzyme (rHuPH20). rHuPH20 has been shown to remove traditional limitations on the volume of biologics that can be delivered subcutaneously (just under the skin). By using rHuPH20, some biologics and compounds that are administered intravenously may instead be delivered subcutaneously. ENHANZE technology may also benefit subcutaneous biologics by reducing the need for multiple injections. This delivery method has been shown in studies to reduce health care practitioner time required for administration and shorten time for drug administration.

About Halozyme
Halozyme Therapeutics is a biotechnology company focused on developing and commercializing novel oncology therapies that target the tumor microenvironment. Halozyme's lead proprietary program, investigational drug pegvorhyaluronidase alfa (PEGPH20), applies a unique approach to targeting solid tumors, allowing increased access of co-administered cancer drug therapies to the tumor in animal models. PEGPH20 is currently in development for metastatic pancreatic cancer, non-small cell lung cancer, gastric cancer, metastatic breast cancer and has potential across additional cancers in combination with different types of cancer therapies. In addition to its proprietary product portfolio, Halozyme has established value-driving partnerships with leading pharmaceutical companies including Roche, Baxalta, Pfizer, Janssen, AbbVie, Lilly, Bristol-Myers Squibb and Alexion for its ENHANZE drug delivery technology.

Actual results could differ materially from the expectations contained in forward-looking statements as a result of several factors, including unexpected expenditures and costs, unexpected fluctuations or changes in revenues, including revenues from collaborators, unexpected delays in entering into new collaboration agreements, unexpected results or delays in development of product candidates, including delays in clinical trial patient enrollment and development activities of our collaboration partners, and regulatory review, regulatory approval requirements, unexpected adverse events and competitive conditions.
