August 2016 Newsletter

We’re pleased to report several developments since our last newsletter, including important milestones for Tocagen and our lead gene therapy product candidate, Toca 511 & Toca FC. Below are some highlights:

  • We were inspired by recent visits from two of our patients who are participating in our Phase 1 trials. They shared with us their experiences as brain cancer survivors and how they are enjoying life.
  • Our potential registrational Phase 2/3 Toca 5 trial is enrolling brain cancer patients at 46 sites in the U.S. and Canada.
  • Our science and progress has been reported by the media, including multiple TV segments including CBS, Fox, and NBC and an article featured in U.S. News & World Report.
  • We launched a new blog that provides tips for brain cancer patients and their caregivers, authored by well-known patient advocate Mary Lovely, Ph.D., RN, CNRN.
  • Tocagen scientists published three peer-reviewed articles, including our first clinical paper, which was selected for the cover of the prestigious journal Science Translational Medicine.
  • Our scientists presented new preclinical and clinical data at key conferences, including ASCO, ASGCT and AACR.

Stay tuned for more updates, and we are grateful for your continued support in our fight against cancer!

The Tocagen team.

Translational Medicine 100Tocagen Article Selected for the Cover of Science Translational Medicine

Data showing Toca 511 & Toca FC extended survival in patients with recurrent brain cancer compared to an external control were featured on the cover of Science Translational Medicine. This important milestone was Tocagen’s first clinical manuscript and was widely covered by the media, including national, industry and local outlets, who also profiled patients doing well on the trial. We even made it into Google’s Top Stories! The study was also shared on social media, including by the National Cancer Institute. The abstract of the paper, authored by Timothy Cloughesy, M.D., of University of California, Los Angeles, can be found here.

Additional Tocagen Data Publishes

Kader Yagiz, Ph.D., and co-authors, published preclinical research in Neuro-Oncology demonstrating that Toca 511 & 5-FC in combination with lomustine showed anticancer activity and immune activation against tumors. Read the abstract.

Amy Lin, Ph.D., and co-authors, reported new data about the stability of Toca 511 viral replication in Human Gene Therapy Methods. Read the abstract.
