Tocagen to Present Clinical and Preclinical Data at Three Scientific Meetings

SAN DIEGO – May 13, 2016Tocagen Inc., a clinical-stage, cancer-selective gene therapy company, today announced that results from the clinical investigation of Toca 511 & Toca FC for the treatment of recurrent high grade glioma will be presented at the 2016 American Society of Clinical Oncology (ASCO) Annual Meeting, to be held June 3-7 in Chicago, and the 17th Biennial Canadian Neuro-Oncology (CNO) Meeting, to be held June 9-11 in Toronto.

In addition, preclinical data demonstrating that Tocagen’s investigational therapy induces an anti-tumor immune response will be presented at Immunology 2016TM, the Annual Meeting of the American Association of Immunologists (AAI), to be held May 13-17 in Seattle.

About Tocagen
Tocagen is a clinical-stage, cancer-selective gene therapy company focused on developing first-in-class, broadly applicable product candidates designed to activate a patient’s immune system against their own cancer from within. The company is developing its lead investigational product candidate, Toca 511 (vocimagene amiretrorepvec) & Toca FC (extended-release 5-fluorocytosine), initially for the treatment of recurrent high grade glioma (HGG), a disease with significant unmet medical need. Tocagen has initiated the Phase 2 portion of a randomized, controlled Phase 2/3 clinical trial of Toca 511 & Toca FC in patients with recurrent HGG, which is designed to serve as a potential registrational trial. More information about the clinical trial can be found at www.tocagen.com/toca5. In 2016, Tocagen plans to initiate clinical trials of Toca 511 & Toca FC in patients with newly diagnosed HGG and other solid tumors. Tocagen obtained Fast Track designation from the U.S. Food and Drug Administration, for Toca 511 & Toca FC for the treatment of recurrent HGG and Orphan drug designation for the treatment of glioblastoma (GBM), a subset of HGG. Tocagen has received grant support from leading brain cancer foundations, including Accelerate Brain Cancer Cure (ABC2), National Brain Tumor Society (NBTS), American Brain Tumor Association (ABTA), Musella Foundation and Voices Against Brain Cancer (VABC).
