Dr. Jacqueline Shea, President and Chief Executive Officer, said: "During the second quarter, we focused on reshaping our organizational structure to help us achieve our product development goals. These efforts included strengthening our executive and R&D teams by appointing Dr. Michael Sumner as our Chief Medical Officer and extending our cash runway into the third quarter of 2024 through cost-savings measures and a corporate restructuring effort."

Dr. Shea continued: "During the quarter we also focused on advancing our strategies for those programs that have the greatest potential to deliver DNA medicine technology to the market. Those programs include our heterologous booster program for our COVID-19 vaccine candidate, INO-4800, as well as our HPV-associated programs. We were also encouraged by positive Phase 1/2 data presented at ASCO involving INO-5401, when used in combination with PD-1 inhibitor, Libtayo®, against glioblastoma. With several additional pipeline milestones expected over the next several months, I look forward to sharing our progress in advancing our DNA medicines towards commercialization in the second half of 2022."

Second Quarter 2022 Corporate Updates

Extended Cash Runway into Third Quarter 2024 – INOVIO announced a corporate reorganization designed to extend its cash runway and support the Company's focus on key clinical programs with the goal of driving long-term growth. The reorganization, which included an 18% workforce reduction in full-time employees and an 86% reduction in contractors, along with other cost-saving measures, is expected to reduce operating expenses by approximately 30% over the next 18 months and extend INOVIO's cash runway into the third quarter of 2024. These projections do not include any funds that may or may not be raised during the time period through the Company's existing at-the-market program or other fundraising mechanisms. INOVIO expects a one-time restructuring charge of approximately $1.6 million in the third quarter of 2022 related to the headcount reduction.

Strengthened Executive and R&D Teams – INOVIO announced the appointment of Dr. Michael Sumner, MB BS, MBA, as Chief Medical Officer. Dr. Sumner brings more than 25 years of extensive pharmaceutical, medical and clinical experience driving numerous late-stage product approvals and supporting successful commercial products on a global basis across multiple therapeutic areas. Dr. Sumner now oversees INOVIO's entire clinical-stage pipeline of DNA medicines, as well as global clinical development, clinical operations and biostatistics efforts, and regulatory affairs, pharmacovigilance and medical affairs.

Presented Positive Clinical Data for INO-5401 at ASCO – INOVIO announced additional results from a Phase 1/2 trial involving INO-5401 and INO-9012 at the 2022 American Society of Clinical Oncology (ASCO) Annual Meeting held in June. In the trial, INO-5401 + INO-9012 was observed to have favorable tolerability and immunogenicity results when administered with Libtayo® and RT/TMZ (radiation and temozolomide) to newly diagnosed GBM patients. Notably, INO-5401 + INO-9012 elicited antigen-specific T cells that may infiltrate GBM tumors.

Second Quarter 2022 Financial Results

INOVIO reported total revenue was $784,000 for the three months ended June 30, 2022, compared to $273,000 for the same period in 2021. The increase in revenue resulted from the delivery of INOVIO's proprietary smart devices related to its contract with the U.S. Department of Defense. Total operating expenses for the three months ended June 30, 2022, were $104.9 million compared to $83.5 million for the same period in 2021.

INOVIO's net loss for the three months ended June 30, 2022, was $108.5 million, or $0.46 per basic and diluted share, compared to net loss of $82.1 million, or $0.39 per basic and diluted share, for the quarter ended June 30, 2021.

Operating Expenses

Research and development (R&D) expenses for the three months ended June 30, 2022, were $56.5 million compared to $70.8 million for the same period in 2021. The decrease in R&D expenses was primarily due to $21.9 million in lower expenses related to the acquisition and installation of manufacturing equipment for INO-4800 during 2021 were non-recurring, and $7.0 million in lower engineering services and expensed equipment related to our CELLECTRA® 3PSP device array automation project. These decreases were partially offset by an $8.3 million increase in drug manufacturing costs related to our COVID-19 variant studies and a Defense Advanced Research Projects Agency COVID-19 dMAb grant, as well as $6.9 million lower contra-research and development expense recorded from grant agreements, among other variances.

General and administrative (G&A) expenses were $48.5 million for the three months ended June 30, 2022, versus $12.7 million for the same period in 2021. The significant increase in G&A expenses in the 2022 second quarter was primarily due to a $14.0 million non-cash expense related to the proposed settlement of INOVIO's previously disclosed securities class action litigation, including the proposed issuance of INOVIO common stock as part of the settlement, and other related litigation costs, as well as $6.9 million in one-time severance expenses related to the separation of INOVIO's former president and chief executive officer, among other variances. The proposed settlement still requires court approval, but has been agreed to, in principle.

Capital Resources

As of June 30, 2022, cash and cash equivalents and short-term investments were $348.1 million compared to $401.3 million as of December 31, 2021. As of June 30, 2022, INOVIO had 247.5 million shares of common stock outstanding and 267.8 million shares of common stock outstanding on a fully diluted basis, after giving effect to the exercise, vesting and conversion, as applicable, of its outstanding options, restricted stock units, convertible preferred stock, and convertible debt.

About INO-4800

INO-4800 is INOVIO's clinical-stage DNA vaccine candidate targeting the spike protein of the SARS-CoV-2 virus. INOVIO has conducted clinical trials with INO-4800 as a primary vaccine candidate that demonstrated it was well tolerated and generated an immune response consisting of both a humoral response (including neutralizing antibodies) as well as cellular responses (generation of both CD4+ and CD8+ T cells). In 2022, INOVIO began developing a strategy to explore the use of INO-4800 as a heterologous booster vaccine.

About VGX-3100

VGX-3100 is INOVIO's clinical-stage DNA medicine product candidate being developed as a potential treatment for several diseases associated with the human papillomavirus (HPV). It is designed to elicit T cell immune responses against the E6 and E7 proteins of HPV types 16 and 18, which are known to be associated with different pre-cancerous conditions and cancer. INOVIO has conducted several clinical trials with VGX-3100 targeting cervical, anal, and vulvar high-grade squamous intraepithelial lesions (HSIL), which are precursors to cancer.

About INO-5401

INO-5401 is INOVIO's clinical-stage DNA medicine product candidate being developed as a potential treatment for glioblastoma (GBM), a rapidly growing and aggressive tumor of the brain and spine. INO-5401 is designed to enhance T cell immune responses against three known tumor-associated antigens commonly expressed in a variety of cancers: human telomerase (hTERT), Wilms tumor gene-1 (WT1), and prostate-specific membrane antigen (PSMA). GBM is an almost universally fatal disease with treatment essentially unchanged for the last decade.

About CELLECTRA® Delivery Technology

INOVIO's DNA medicines are delivered into cells of the body using its investigational proprietary CELLECTRA smart device, either intramuscularly (IM) or intradermally (ID). CELLECTRA devices use brief (millisecond-long) electrical pulses to reversibly create small pores in the cell membrane, enhancing intracellular uptake of DNA medicines by more than a thousand-fold compared to the injection of a DNA medicine without this delivery enhancement technique.

About INOVIO

INOVIO is a biotechnology company focused on developing and commercializing DNA medicines to help treat and protect people from infectious diseases, cancer, and diseases associated with HPV. Our DNA medicines are delivered using our proprietary smart device to produce immune responses against targeted pathogens and cancers. For more information, visit www.inovio.com.
