Inovio anticipates for 2020 to be a transformative year for the company. At the Biotech Showcase 2020 presentation,Dr. Kim will highlight multiple value-driving catalysts,clinical development,and program readouts which are all expected this year.

VGX-3100/INO-3107: HPV-Related Diseases

VGX-3100. Inovio expects to report VGX-3100 REVEAL 1 top-line efficacy data in the fourth quarter of 2020. Through extensive work on amending the clinical readout timing a year earlier than originally designed,these early top-line data will be made available without compromising the integrity of both REVEAL 1 and REVEAL 2 trials. If positive,Phase 3 top-line data could provide further regulatory validation for this first-in-class DNA Medicine for treating cervical dysplasia.

INO-3107. Inovio continues to expand its DNA Medicine franchise to treat HPV-related diseases by advancing INO-3107 to treat RRP,an orphan disease indication with a potential accelerated regulatory pathway.

In the first half of this year,Inovio plans to initiate a Phase 2 clinical trial of INO-3107 for RRP,which impacts both pediatric and adult patients. RRP is caused by HPV 6 and 11 infections,which form non-cancerous tumors in the airways of patients who suffer from this disease. Currently,the disease is incurable and can only be treated by frequent surgeries to remove the tumors,which temporarily restores the airway before renewed tumor growth.

In a previous pilot study,two adult patients with RRP had required surgery approximately every six months to clear tumor growth from their throats. Since their last dose of Inovio's HPV product candidate,both patients have been able to avoid or significantly delay surgery. One patient has not needed surgery for almost three years as of the last follow-up. The other patient did not require surgical intervention for approximately one and a half years,a significant delay in surgery intervals prior to the trial enrollment.

Inovio believes INO-3107 could provide a novel treatment option for patients and a significant commercial opportunity for Inovio. Inovio is fully committed to bringing this product candidate to the market as soon as possible using all of the regulatory and development pathways available for rare,orphan diseases.

Dr. J. Joseph Kim,Inovio's President & CEO said,"In July,Inovio management took the difficult but necessary step to streamline expenses and prioritize our pipeline candidates. We have also accelerated important REVEAL 1 top-line data readout to the fourth quarter of 2020,allowing the market and potential global partners to see this data sooner than expected and moved to rapidly advance INO-3107,an orphan eligible and fast-to-market product candidate.

"Looking ahead,the coming year sets up to be a transformational period for Inovio,with top-line efficacy data from our REVEAL 1 Phase 3 trial,in addition to INO-5401 Glioblastoma overall survival data at months 12 and 18 and expected MEDI0457 head and neck cancer results from AstraZeneca. These upcoming trial results in 2020 will be important drivers for the achievement of Inovio's long-term strategy and maximizing the commercial potential of our DNA Medicine pipeline."

INO-5401/Glioblastoma Multiforme (GBM) Phase 2 Trial

INO-5401. Inovio will report 12- and 18-month overall survival data in 2020. Last year,Inovio reported promising progression-free survival at six months from its ongoing Phase 2 trial of newly diagnosed glioblastoma multiforme (GBM),which combines Inovio's product candidates INO-5401,a T cell-activating immunotherapy encoding for three tumor-specific antigens (hTERT,WT1,and PSMA),and INO-9012,an immune activator,in combination with Libtayo®,a PD-1 blocking antibody produced by Regeneron Pharmaceuticals in collaboration with Sanofi.

Key interim data from the 52-patient clinical trial showed that 80% (16 of 20) of MGMT gene promoter methylated patients and 75% (24 of 32) of unmethylated patients were progression-free at six months measured from the time of their first dose,significantly exceeding historical standard-of-care data. The majority of patients tested had a T cell immune response to one or more tumor-associated antigens encoded by INO-5401. Immune responses to all three tumor-associated antigens were demonstrated in this trial. The interim data were presented at the Society for Immunotherapy of Cancer (SITC) 2019 Annual Meeting.

INO-5151/Prostate Cancer Combination Trial

INO-5151. Parker Institute-funded cancer combination trial using INO-5151 in metastatic castration-resistant prostate cancer patients is currently enrolling. INO-5151 is a formulation that combines INO-5150 (with antigens encoding for PSA and PSMA) with INO-9012 (a T-cell activator). INO-5151 is being tested in one arm (Cohort C) of this immunotherapy combination study along with nivolumab,a PD-1 inhibitor (Bristol-Myers Squibb),and CDX-301 (Celldex Therapeutics).

Infectious Diseases/New Product Development Candidates

INO-4500. In 2020,Inovio will present Phase 1,first-in-human clinical trial evaluating INO-4500,its candidate vaccine to prevent infection from the Lassa virus. This Inovio trial conducted in the U. S. represents the first Lassa candidate vaccine to enter the clinic. This Inovio-sponsored trial,as well as its INO-4500 program,is fully funded through a global partnership with CEPI – the Coalition for Epidemic Preparedness Innovations. Inovio is also planning to advance INO-4500 to a Phase 1b trial in Africa in 2020.

INO-4700. In 2020,Inovio expects to advance INO-4700,its candidate vaccine against MERS (Middle East Respiratory Syndrome),into a Phase 2 field study in the Middle East and Africa where outbreaks have been observed,with full funding from CEPI. This is the most advanced vaccine candidate for MERS.

INO-A002. Inovio expects to report results in 2020 from its first-in-human trial of dMAb candidate INO-A002 (for preventing or treating Zika virus infection) from a Phase 1 dose-escalation trial to assess safety and tolerability and expression of dMAb-produced antibodies with full funding from the Bill & Melinda Gates Foundation. Using direct local delivery into the body,the synthetic genetic codes provided by the dMAb plasmids instruct the body's cells to become a customized patient-specific factory that manufactures its own therapeutic monoclonal antibodies,enabling a major leap in antibody technology. With its plasmid design and in-patient production,dMAb products represent a disruptive and innovative entrant to this important class of pharmaceuticals.

About Inovio

Inovio is a biotechnology company focused on rapidly bringing to market precisely designed DNA medicines to treat,cure and/or protect people from diseases associated with HPV,cancer,and infectious diseases.
