Virion Therapeutics Presents Promising Preclinical Cancer Data When Using a Novel Genetically Encoded Checkpoint Modifier-Based Immunotherapy

On March 6, 2023 Virion Therapeutics, LLC, a clinical-stage biotech company focused on the development of novel, adaptable, and accessible CD8+ T cell-based technologies focused on cancers and infectious diseases, reported data of a genetically encoded checkpoint modifier-based immunotherapy, which enhances CD8+ T cell activation, in a fast-growing preclinical tumor model at the ESMO (Free ESMO Whitepaper) Target Anticancer Therapies Congress in Paris France (Press release, Virion Biotherapeutics, MAR 6, 2023, View Source [SID1234628219]).

Top line results, following a single intramuscular injection of this novel immunotherapy include:

Enhanced immune responses (10- to 15-fold) to oncogenic antigens
At study completion, 100% survival (n=30/30), 100% initial tumor clearance (n=30/30), and 93% of animals were tumor free (n=28/30)
In contrast, all mice treated with a control vaccine experienced rapid tumor growth and death by Day 30 (n=20)
These results were durable and reproducible across multiple treatment groups and studies
"Glycoprotein D (gD), when genetically expressed as a fusion protein with antigen(s) of choice, enhances, broadens, and prolongs CD8+ T cell responses. In this preclinical model of fast-growing HPV-16-associated tumors, a gD-based immunotherapy against HPV-16 provided incredibly strong protection against tumor growth and death," said Hildegund Ertl, MD, Professor, Vaccine & Immunotherapy Center, at The Wistar Institute in Philadelphia PA and Scientific Co-Founder of Virion Therapeutics. "Targeting different checkpoints of early T cell activation represents a novel approach to overcoming T cell impairments during tumor progression and these data further support its potential application, alone or in combination with other checkpoint inhibitors, for a wide range of cancers."

"These preclinical oncology data demonstrated treatment responses which were profound, durable, and reproducible – and show clear differentiation to any other immunotherapy or vaccine in development. We are excited to be advancing our checkpoint modifier pipeline, not only with IND-enabling activities for our oncology program, but also, VRON-0200, for chronic HBV, which is heading to the clinic this summer," said Andrew Luber, Pharm.D., President, and chief executive officer of Virion.

About Genetically Encoded Checkpoint Modifiers (gCPM)

Virion is developing a series of novel gCPMs which act at different stages of T cell activation. The lead gCPM, glycoprotein D (gD), works by blocking an inhibitory signal of early activation (e.g., BTLA/CD160), thereby allowing a co-stimulatory signal to predominate (e.g., LIGHT) – the resultant CD8+ T cells that are induced to the target antigen(s) are enhanced, broadened and prolonged and they are more resistant to becoming impaired over time. This novel mechanism of early checkpoint modification that acts locally at the onset of the immune response has shown promising therapeutic efficacy in several settings, including animal models of fast and slow growing tumors, with viral or human cancer antigens, in young and older animals, and when inserted into DNA or adenovirus vaccine delivery platforms (both human and chimpanzee).

Under the terms of the agreement, Phanes will receive a technology access payment and further collaborative research support. The details of the financial terms were not disclosed.

"We are delighted to have the opportunity to collaborate with Xyphos," said Dr. Ming Wang CEO of Phanes. "PACbody and SPECpair allow construction of native IgG-like bispecific antibodies and production of the molecules using the conventional manufacturing process for monoclonal antibodies. The lead molecule Phanes made using these technologies has entered Phase 1 clinical study. With the bispecific antibody technology platforms we have built, Phanes is well positioned to make important impacts in cell therapies."

Upcoming Milestones and Events

•Pivotal Study Planning. The Company is preparing to initiate the first of two pivotal, placebo-controlled clinical trials of TTP399 in subjects with T1D following FDA clearance. The studies are expected to recruit approximately 1,000 patients and at least one of the studies will assess one year of treatment. The FDA and the Company have agreed on the primary endpoint for the studies as the difference between the placebo and

TTP399-treated groups in number of hypoglycemic events. The Company expects to commence launch activities in connection with the Phase 3 trials in the second half of 2023.
•Phase 2 Study in Type 2 Diabetes. In collaboration with an affiliate of G42 Investments, the Company is preparing to sponsor a Phase 2 study comparing TTP399 with placebo in approximately 600 patients with Type 2 diabetes on insulin therapy. This study is expected to be initiated in 2023.
Fourth Quarter 2022 Financial Results
•Cash Position: The Company’s cash position as of December 31, 2022, was $12.1 million compared to $13.4 million as of December 31, 2021.

•Research & Development (R&D) Expenses: R&D expenses were $4.0 million and $5.4 million in each of the three months ended December 31, 2022, and 2021, respectively. The decrease of $1.4 million is attributable to i) a decrease in spending related to a multiple ascending dose study for HPP737 due to its completion in 2021, ii) a license payment to Novo Nordisk for the completion of TTP399 phase 2 studies in 2021, and iii) lower payroll and severance costs, offset by higher spending on TTP399 due to drug product related costs and trial preparation costs.
•General & Administrative (G&A) Expenses: G&A expenses were $2.4 million and $5.7 million for each of the three months ended December 31, 2022, and 2021, respectively. The decrease of $3.3 million was due to lower payroll and severance costs offset by higher other G&A costs.
•Other Income: Other income for the three months ended December 31, 2022, was $0.1 million and was driven by gains related to the change in the fair value of the outstanding warrants to purchase shares of our own stock issued to related parties ("Related Party Warrants"), partially offset by an unrealized loss recognized related to the Company’s investment in Reneo. Other income for the three months ended December 31, 2021, was $1.6 million and was related to the unrealized gains recognized related to the investment in Reneo, as well as gains related to the change in the fair value of the outstanding warrants in our own stock held by a related party.
•Net Loss: Net loss attributable to vTv shareholders for the three months ended December 31, 2022, was $4.7 million or $0.06 per basic share. Net loss attributable to vTv shareholders for the comparable period a year ago was $7.1 million or $0.11 per basic share.

The decrease is attributable to i) a decrease in clinical trial costs for azeliragon, which was mainly driven by discontinuance of its development as a potential treatment of Alzheimer’s disease in patients with type 2 diabetes, ii) a decrease in spending related to a multiple ascending dose study for HPP737 due to its completion in 2021, iii) a license payment in 2022 to Novo Nordisk for the completion of TTP399 phase 2 studies in 2021, and iv) lower payroll and severance costs, offset by higher spending on TTP399 due to drug product related costs and trial preparation costs.
•General & Administrative (G&A) Expenses: G&A expenses were $12.2 million and $12.3 million for each of the years ended December 31, 2022, and 2021, respectively. The decrease of $0.1 million was due to lower payroll and severance costs offset by higher legal expense and other G&A costs.
•Other (Expense)/Income: Other expense for the year ended December 31, 2022, was $2.7 million and was driven by an unrealized loss recognized related to the Company’s investment in Reneo, offset by gains related to the change in the fair value of the outstanding warrants to purchase shares of our own stock issued to related parties.
