Title: Enhanced Efficacy and Combinability of Low Dose Toca 511 and 5-FC with Metronomic Chemotherapy in Preclinical Models
Presenter: Sophie Viaud, Ph.D.
Date and Time: Saturday, Nov. 10, 7:00-8:30 p.m. ET
Summary:

This study aimed to determine if the addition of metronomic cyclophosphamide would provide therapeutic benefit when combined with Toca 511 and 5-FC (5- fluorocytosine) in a preclinical, subcutaneous glioma model.
The addition of metronomic cyclophosphamide improved tumor control and survival.
Regulatory T cells were significantly reduced in the peripheral blood with the combination with metronomic cyclophosphamide and CD8+ T cells were significantly increased.
Results support the further evaluation of Toca 511 & Toca FC with metronomic dosing of cyclophosphamide and potentially other chemotherapeutics.

Title: PD-L1 Checkpoint Blockade Using a Single-Chain Variable Fragment Targeting PD-L1 Delivered by Retroviral Replicating Vector (Toca 521) Enhances Anti-Tumor Effect in Cancer Models
Presenter: Amy Lin, Ph.D.
Date and Time: Wednesday, Nov. 14, 1:35-1:45 p.m. CST
Summary:

Toca 521, a retroviral replicating vector (RRV) expressing a single-chain variable fragment (scFv) targeting PD-L1, was developed using Tocagen’s proprietary cancer-selective gene therapy platform technology.
Preclinical results demonstrated Toca 521 reversed PD-1/PD-L1 mediated immune suppression in a human in vitro cell culture system, and conferred robust, durable and highly selective anti-tumor activity compared to systemically administered anti-PD-1 or anti-PD-L1 monoclonal antibodies.
Plasma levels of scFv PD-L1 were equivalent to negative control levels and hence very low compared to reported levels in humans given systemic anti-PD1/PD-L1 therapy.
These results warrant further development of Toca 521 to investigate the potential for improved safety and efficacy profiles compared to systemic monoclonal antibodies against the same checkpoint target. Toca 521 could also be useful in combination with other agents, including immuno-oncology therapies.
Details of the SNO presentation are as follows:

Presentation Type: Poster (Abstract: ATIM-26)
Title: Immunologic trends associated with recurrent high grade glioma patient outcomes in a Phase 1 clinical trial of Toca 511 and Toca FC
Presenter: William Accomando, Ph.D.
Date and Time: Saturday, Nov. 17, 5:00-7:00 p.m. CST
Summary:

Human immune monitoring results from a Phase 1 clinical trial of Toca 511 & Toca FC support an immune-related mechanism of action for the regimen.
Preliminary analyses identified immunologic biomarkers that can potentially predict, with high sensitivity and selectivity, patient outcomes following treatment with Toca 511 & Toca FC.
These results indicate the value of evaluating potential biomarkers of patient outcomes in the ongoing randomized Toca 5 Phase 3 trial in patients with recurrent HGG.
About Toca 511 & Toca FC
Tocagen’s lead product candidate is a two-part cancer-selective immunotherapy comprising 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.

"We are pleased to report continued progress from each of the three clinical programs evaluating differentiated and novel therapeutics enabled by our proprietary peptide engineering platform," commented Dinesh V. Patel, Ph.D., Protagonist President and Chief Executive Officer. "We recently presented safety and efficacy data from the Phase 2 PROPEL study. Notably, these data show dose-dependent histologic remission in ulcerative colitis patients. The cumulative data for PTG-100, which now includes clinical, endoscopic, histologic and biomarker data, is supportive of the GI-restricted, oral targeted therapy approach for potential treatment of inflammatory bowel diseases."

"In addition, we recently announced successful completion of the Phase 1 clinical trial of the oral interleukin-23 receptor antagonist PTG-200. We are working closely with our partner Janssen Biotech to support the U.S. IND filing for a Phase 2 Crohn’s trial in the coming months."

"Our hepcidin mimetic PTG-300 is on track for initiation of an open label, global, phase 2 trial in beta-thalassemia patients by year end. We are encouraged to note that PTG-300 now has Orphan Drug Designation both from the U.S. FDA and European Medicines agency, as well as Fast Track designation from the U.S. FDA for beta-thalassemia."

Product Development Update:

PTG-100

· Clinical data from the PROPEL Study presented at the recent United European Gastroenterology Week demonstrated that treatment with PTG-100, an oral, gut-restricted alpha-4-beta-7 integrin antagonist peptide, was well tolerated and associated with higher rates of clinical remission relative to placebo.

· The dose-dependent increase in rates of histologic remission, the blood biomarker data and topline safety data presented at the meeting expand upon the clinical remission and endoscopic response results announced previously in August 2018 that involved an independent, blinded re-read of endoscopies and had demonstrated signals of clinical efficacy.

· The totality of the data from the Phase 2 PROPEL study in UC patients provides first evidence of safety and clinical efficacy with an oral alpha-4-beta-7-integrin specific antagonist agent and supports further development of PTG-100.

PTG-200

· The Phase 1 study of PTG-200, an oral peptide IL-23 receptor antagonist partnered with Janssen Biotech, was successfully completed. Top-line results from this randomized, double-blind, placebo-controlled, single- and multiple-dose escalation study in 80 normal healthy volunteers demonstrated that PTG-200 treatment was well tolerated, with no serious adverse events or dose-limiting toxicities observed. Pharmacokinetic and pharmacodynamic parameters were consistent with the gastrointestinal-restricted design of PTG-200.

· Results from this study provide the first clinical data in support of PTG-200 and creates a path forward for its evaluation as a potential first-in-class oral IL-23 pathway based therapeutic for treatment of IBD.

·Protagonist and Janssen Biotech are working towards filing a U.S. IND in the coming months to support a Phase 2 clinical study in Crohn’s disease patients.

PTG-300

·The Company remains on track to initiate a global Phase 2 clinical trial in beta-thalassemia patients in the fourth quarter of 2018.

· The U.S. FDA granted Fast Track Designation to PTG-300 for the treatment of chronic anemia due to ineffective erythropoiesis in patients with beta-thalassemia. This designation will facilitate the future development and expedite the review process of PTG-300.

· The European Medicines Agency granted Orphan Drug Designation to PTG-300 in the treatment of beta-thalassemia. Orphan drug designation from the US FDA had been previously granted for PTG-300 for potential treatment of beta-thalassemia. An orphan designation provides regulatory and financial incentives for development as well as certain benefits upon regulatory approval, if received.

Corporate Update — Financing:

· Protagonist announced the completion of a financing with investors including BVF Partners L.P. and their affiliates for gross proceeds of $22 million in August 2018. This enables the company to fund the development of its multiple clinical assets in diverse disease indications addressing unmet medical needs.

Financial Results

Protagonist reported a net loss of $8.7 million and $25.1 million, respectively, for the third quarter and first nine months of 2018, as compared to a net loss of $4.8 million and $33.9 million, respectively, for the same periods of 2017. The increase in net loss for the third quarter of 2018 as compared to the prior year period was driven primarily by a decrease in revenue under the Janssen Collaboration Agreement related to proportional performance as measured by actual costs incurred as a percentage of budgeted costs, and increases in research and development (R&D) and general and administrative (G&A) expenses. The decrease in net loss for the first nine months of 2018 as compared to the prior year period was driven primarily by an increase in revenue under the Janssen Collaboration Agreement, which became effective in the third quarter of 2017, partially offset by increases in R&D and G&A expenses. The net loss for the third quarter and first nine months of 2018 includes non-cash stock-based compensation of $2.0 million and $4.8 million, respectively, as compared to $1.2 million and $3.1 million, respectively, for the same periods of 2017.

R&D expenses for the third quarter and first nine months of 2018 were $12.1 million and $45.2 million, respectively, as compared to $11.2 million and $34.5 million, respectively, for the same periods of 2017. The increases in R&D expenses were primarily due to costs related to contract manufacturing and the preparation for and conduct of clinical trials for our product candidates. R&D expenses for the third quarter and first nine months of 2018 included increases in salaries and employee-related expenses due to an increase in R&D personnel.

G&A expenses for the third quarter and first nine months of 2018 were $3.4 million and $10.2 million, respectively, as compared to $2.6 million and $8.7 million, respectively, for the same periods of 2017. The increases in G&A expenses were primarily due to increases in salaries and employee-related expenses to support the growth of our operations.

Protagonist ended the third quarter with $138.5 million in cash, cash equivalents and investments. The company expects to have sufficient financial resources to fund operations to mid-2020.
