Tocagen Reports Fourth Quarter and Full Year 2017 Financial and Business Results

SAN DIEGO, March 8, 2018 /PRNewswire/ -- Tocagen Inc. (Nasdaq: TOCA), a clinical-stage, cancer-selective gene therapy company, today reported financial results and business highlights for the fourth quarter and full year ended December 31, 2017.

"We had an excellent finish to the year with the acceleration of Toca 511 & Toca FC development into a pivotal Phase 3 trial and the presentation of updated data demonstrating continued favorable safety and long-term durable responses in patients with recurrent high-grade glioma," said Marty Duvall, chief executive officer of Tocagen. "With the closing of our upsized public offering in 2017 and enrollment in our Phase 3 trial remaining on track to complete in 2018, we believe we are well positioned to advance our lead program and platform technology in the year ahead."

Fourth Quarter 2017 and Recent Progress

• Acceleration of Toca 511 & Toca FC into pivotal Phase 3 trial: In October 2017, based on Tocagen's communications with the U.S. Food and Drug Administration (FDA) under Breakthrough Therapy Designation, Tocagen accelerated Toca 511 & Toca FC clinical development by modifying the original two-step trial design (Phase 2 followed by a Phase 3) into a seamless, pivotal Phase 3 trial, known as the Toca 5 trial.
• Updated durable complete response data presented: In October 2017, research collaborators presented updated durable complete response data from a Phase 1 trial of Toca 511 & Toca FC in patients with high-grade glioma (HGG), a type of brain tumor, at the AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics. In addition to a continued favorable safety profile, six complete responses were reported for which the median duration of response had not been reached after nearly three years of follow up.
• Orphan medicinal product designation granted from EMA: In March 2018, Tocagen announced the European Medicines Agency granted orphan medicinal product designation to Toca 511 (vocimagene amiretrorepvec) & Toca FC (flucytosine) for the treatment of patients with glioma.
• Publication of preclinical data: In December 2017, data were published in Molecular Therapy ? Oncolytics demonstrating the efficacy of intravenous (IV) administration of Toca 511 and 5-FC in a preclinical model of metastatic colorectal cancer, and in Human Gene Therapy demonstrating retroviral replicating vectors' ability to selectively deliver multiple genes to cancer cells.

2018 Milestones

• Complete enrollment of pivotal Phase 3 Toca 5 trial in recurrent HGG.
• Report Toca 6 activity and safety data in metastatic solid tumors.
• Update European regulatory path under PRIME (PRIority MEdicines) designation.
• Advance clinical development plan evaluating Toca 511 & Toca FC in newly diagnosed HGG.
• Advance Tocagen's retroviral replicating vector platform with anti-PD-L1 in investigational new drug (IND)-enabling studies.

Fourth Quarter 2017 Financial Results

Research and Development (R&D) Expenses: R&D expenses were $8.3 million for the quarter ended December 31, 2017, compared to $6.6 million for the quarter ended December 31, 2016. The R&D expenses in both periods were primarily driven by costs to support the Toca 5 trial and to support the manufacturing of drug product. The increase in 2017 reflects primarily higher personnel costs as compared to the same period in 2016.

General and Administrative (G&A) Expenses: G&A expenses were $2.4 million for the quarter ended December 31, 2017, compared to $1.4 million for the quarter ended December 31, 2016. The increase in G&A expenses was primarily due to higher costs to support increased operations activity and costs associated with being a public company during the fourth quarter of 2017, including a $0.5 million increase in stock-based compensation compared to the same period in the prior year.

Net Loss: Net loss was $10.8 million, or $0.55 per common share (basic and diluted), for the quarter ended December 31, 2017, compared to a net loss of $8.4 million, or $3.83 per common share (basic and diluted), for the quarter ended December 31, 2016. The 2017 calculation is based on 19.8 million average common shares outstanding for the fourth quarter of 2017, compared to 2.2 million average common shares outstanding for the fourth quarter of 2016.

2017 Twelve-Month Results

R&D Expenses: R&D expenses were $29.1 million for the 12 months ended December 31, 2017, compared to $27.2 million for the 12 months ended December 31, 2016. The increase in R&D expenses primarily reflects increased personnel costs to support the Toca 5 clinical trial.

G&A Expenses: G&A expenses were $8.6 million for the 12 months ended December 31, 2017, compared to $4.5 million for the 12 months ended December 31, 2016, with the increase primarily driven by higher costs to support increased operations activity and costs associated with being a public company, including a $1.9 million increase in stock-based compensation compared to the same period in the prior year.

Net Loss: Net loss was $38.9 million, or $2.66 per common share (basic and diluted), for the 12 months ended December 31, 2017, compared to a net loss of $33.5 million, or $15.22 per common share (basic and diluted), for the 12 months ended December 31, 2016. The 2017 calculation is based on 14.6 million average common shares outstanding for the 12 months ended December 31, 2017, compared to 2.2 million average shares outstanding for the same period in the prior year.

Cash Position and Guidance

Cash, cash equivalents and marketable securities were $88.7 million at December 31, 2017 compared to $31.2 million at December 31, 2016. In April 2017, Tocagen raised $97.8 million of gross proceeds in an initial public offering (IPO). Based on current operating plans, Tocagen estimates the total cash used in 2018 to fund operations, capital expenditures and debt amortization will not exceed $50 million.

About Toca 511 & Toca FC

Tocagen's lead product candidate is a two-part cancer-selective immunotherapy comprised of an investigational biologic, Toca 511, and an investigational small molecule, Toca FC. Toca 511 is a retroviral replicating vector (RRV) that selectively infects cancer cells and delivers a gene for the enzyme, cytosine deaminase (CD). Through this targeted delivery, only infected cancer cells carry the CD gene and produce CD. Toca FC is an orally administered prodrug, 5-fluorocytosine (5-FC), which is converted into an anti-cancer drug, 5-fluorouracil (5-FU), when it encounters CD. 5-FU kills cancer cells and immune-suppressive myeloid cells resulting in anti-cancer immune activation and subsequent tumor killing.

About Tocagen

Tocagen is a clinical-stage, cancer-selective gene therapy company developing first-in-class, broadly applicable product candidates designed to activate a patient's immune system against their own cancer. Tocagen's lead investigational product candidate, Toca 511 & Toca FC, is under evaluation in a pivotal Phase 3 trial for recurrent high-grade glioma (HGG), a disease with significant unmet medical need. The U.S. Food and Drug Administration (FDA) has granted Toca 511 & Toca FC Breakthrough Therapy Designation for the treatment of recurrent HGG and the European Medicines Agency (EMA) has granted Toca 511 PRIME (PRIority MEdicines) for the treatment of HGG.
