As the year comes to a close, we wanted to share some of our progress since our August 2016 newsletter. Some highlights include:

  • Enrollment in our ongoing Phase 2/3 clinical trial, Toca 5, is going very well at 64 leading brain cancer hospitals in the United States, Canada, Israel and South Korea.
  • New clinical and preclinical data were presented at key scientific conferences, including updated tumor response and survival data.
  • We strengthened our leadership team with the appointment of Martin “Marty” Duvall as our CEO. Our co-founder and former CEO, Harry Gruber, M.D., is now our president of research and development, as well as continuing as a key member of our board of directors.
  • François, a patient in one of our Phase 1 trials, shared his inspiring story of hope and survival.
  • Our science, progress and patient stories continue to be reported by the media.
  • The first patient was enrolled in our new trial evaluating intravenously delivered Toca 511 in metastatic cancers.

We wish you a wonderful holiday season and happy New Year, and remain grateful for your continued support in our fight against cancer!

The Tocagen Team



Toca 5 Trial Actively Recruiting Patients

We have continued to expand the Toca 5 study and are pleased to report the trial is now recruiting patients at 64 leading brain cancer centers in the United States, Canada, Israel and South Korea.

Out and About: Tocagen Team Present New Data

Tocagen’s scientists and management team presented new data at several top scientific and medical conferences. Of particular note, we reported that in the subset of patients (N=24) in the higher dose cohorts that mirror the patient population under evaluation in the ongoing Toca 5 trial, there was a clinical benefit rate of 41.7%, with 3 complete responses, 2 partial responses and 5 patients with stable disease. All patients with an objective response remain alive 24 to 43 months from study entry, and the duration of response was 26.7 months (median not reached). Links to the news releases are listed here:

Inspiring Story from Patient Participating in Tocagen’s Trial

There’s never a good time to hear that you have a brain tumor, but for François, whose wife was about to deliver their first child, the timing couldn’t have been worse. After his tumor returned his doctor recommended Tocagen’s trial and this year he celebrated his son’s fourth birthday. He and his wife recently shared their incredible story with us. Watch the video.

François also shared his experience as a brain cancer patient at a recent patient conference. Watch the full discussion.

Walking, Running and Rappeling to Support the Brain Cancer Community!

The Tocagen team proudly participated in multiple events to help raise awareness and support for brain cancer research and patients.

Over 30 Tocagen employees and their families walked or ran 5K at the San Diego Brain Tumor Foundation’s annual event. This nonprofit provides patients and families in need with financial support for everyday expenses such as rent or mortgage payments, insurance co-pays and utility bills and provides transportation to doctor’s appointments.

Tocagen’s Susan Wilson represented the company when she bravely went over the edge – literally – for brain cancer, rappelling down the side of the largest building on the San Diego waterfront. The event was held by the nonprofit Accelerate Brain Cancer Cure (ABC2) with all proceeds supporting San Diego-based brain cancer research.

New Trial Evaluating Intravenous Delivery of Toca 511 Initiated
