SAN DIEGO, Sept. 17, 2020 /PRNewswire/ -- Halozyme Therapeutics, Inc. (NASDAQ: HALO) today announced that its collaborator, Roche, presented a poster with data from Part 1 of its Phase 1b study (IMscin001) evaluating atezolizumab (Tecentriq®) for subcutaneous administration utilizing Halozyme's ENHANZE® technology in patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) at the ESMO Virtual Congress 2020.

The Phase 1b dose-finding study enrolled 67 patients with advanced/metastatic NSCLC previously treated with chemotherapy (no prior cancer immunotherapy) in 3 cohorts.  The poster concluded that atezolizumab utilizing ENHANZE® was well tolerated, provided similar exposure as atezolizumab IV and that results support further development of subcutaneous atezolizumab in IMscin001 Part 2, a confirmatory phase III study.

"We are pleased that the results from Roche's Phase 1b evaluating atezolizumab with ENHANZE® support continued development in a Phase 3 study," said Dr. Helen Torley, president and chief executive officer.

The subcutaneous formulation of atezolizumab is being developed to potentially allow faster administration via subcutaneous injection under the skin, compared to the original intravenous (IV) formulation, thereby significantly reducing a patient's time spent receiving treatment.
