PDS Biotech Provides Business Update and Reports First Quarter 2021 Financial Results

FLORHAM PARK, N.J., May 13, 2021 (GLOBE NEWSWIRE) -- PDS Biotechnology Corporation (Nasdaq: PDSB), a clinical-stage immunotherapy company developing novel cancer therapies and infectious disease vaccines based on the Company’s proprietary Versamune^® T-cell activating technology, will discuss its financial results for the quarter ended March 31, 2021 and provide a business update on its conference call today.

Recent Business Highlights:

•

National Cancer Institute to present interim efficacy and safety data of PDS0101 Phase 2 clinical trial in an oral presentation at the American Society of Clinical Oncology (ASCO) 2021 Annual Meeting on June 7, 2021. This trial is evaluating PDS0101 with two clinical stage immunotherapies from EMD Serono, a first in class bifunctional checkpoint inhibitor Bintrafusp Alfa (M7824) and an antibody conjugated cytokine M9241 (NHS-IL12), in patients with all types of advanced HPV-associated cancers, whose cancer has returned or spread after treatment.

•

COVID-19 consortium received a commitment from the Secretary for Research and Scientific Training of The Ministry of Science, Technology and Innovation of Brazil (MCTI) to fund up to approximately US$60 million to support the clinical development and commercialization of a Versamune^®-based COVID-19 vaccine by Farmacore in Brazil.

“We look forward to the presentation of preliminary efficacy and safety data from the National Cancer Institute (NCI)-led Phase 2 combination study of PDS0101 at the ASCO conference in early June. ASCO provides an important opportunity to present the potential of PDS0101 and the Versamune^® platform in oncology to the research and medical community,” commented Dr. Frank Bedu-Addo, President and Chief Executive Officer of PDS Biotech, “The presentation of the human clinical efficacy data at ASCO is an important milestone both for PDS0101 and our entire Versamune^®-based oncology pipeline.”

First Quarter 2021 Financial Results

PDS Biotech reported a net loss of approximately $3.0 million, or $0.14 per basic share and diluted share, for the three months ended March 31, 2021 compared to a net loss of approximately $4.0 million, or $0.39 per basic share and diluted share, for the three months ended March 31, 2020.

Research and development (R&D) expenses decreased 28% to approximately $1.4 million for the three months ended March 31, 2021 from approximately $2.0 million for the three months ended March 31, 2020. The decrease of approximately $0.6 million in 2021 was primarily attributable to a decrease of $0.3 million in professional services and $0.3 million in clinical studies.

General and administrative expenses decreased 21% to approximately $1.6 million for the three months ended March 31, 2021 from approximately $2.1 million for the three months ended March 31, 2020. The decrease of approximately $0.5 million is primarily attributable to a decrease in professional services of approximately $0.7 million which includes legal fees of approximately $0.2 million, offset by an increase of approximately $0.2 million in personnel costs.

Total operating expenses decreased 24% to approximately $3.0 million for the three months ended March 31, 2021 from approximately $4.0 million for the three months ended March 31, 2020.

PDS Biotech’s cash balance as of March 31, 2021 was approximately $25.0 million.

About PDS Biotech

PDS Biotech is a clinical-stage immunotherapy company developing a growing pipeline of cancer immunotherapies and infectious disease vaccines based on the Company’s proprietary Versamune^® T-cell activating technology platform. Our Versamune^®-based products overcome the limitations of current immunotherapy by inducing in vivo, large quantities of high-quality, highly potent polyfunctional tumor specific CD4+ helper and CD8+ killer T-cells. PDS Biotech has developed multiple therapies, based on combinations of Versamune^® and disease-specific antigens, designed to train the immune system to better recognize diseased cells and effectively attack and destroy them. Our immuno-oncology product candidates are initially being studied in combination therapy to potentially enhance efficacy without compounding toxicity across a range of cancer types. The Company’s lead investigational cancer immunotherapy product PDS0101 is currently in Phase 2 clinical studies in HPV-associated cancers.

Introduction to the Versamune® Platform

Versamune® is designed to induce a robust and targeted anti-tumor response in vivo when administered with a tumor-associated antigen 8 Reference: Gandhapudi SK, et al. 2019. Antigen priming with enantiospecific cationic lipid nanoparticles induces potent antitumor CTL responses through novel induction of a Type I IFN response.

Promotes uptake of vaccine or immunotherapy and entry into lymph nodes Promotes antigen processing and presentation to T-cells via MHC I and II pathways Activates Type I Interferon pathway, enabling a powerful anti-tumor killer CD8+ T-cell response Versamune® + Tumor-associated proteins (antigens)

Greater quantity and quality of Versamune®-induced killer T-cells may result in unique ability to eradicate HPV-positive tumors after a single dose 9 Induced a >10-fold number of highly potent T-cells and eradication of HPV-positive tumors after a single dose in preclinical studies Single treatment dose Results typical of current topclinical-stage HPV cancer vaccines Tumor rechallenge at Day 60; complete and sustained cure of cancer *Adjuvant = cytokine GMCSFReferences: J.

J Immunother Cancer. 2020 Dec;8(2):e001395

18 A Phase 2, investigator-initiated clinical trial evaluating PDS0101 in combination with chemoradiation therapy in patients with advanced cervical cancer Indication Treatment of patients with locally advanced cervical cancer – Stages IB3-IVA Clinical Agents Chemoradiotherapy (CRT – Standard of Care): Cisplatin & radiation therapyPDS0101: Versamune®-based immunotherapy generating HPV-specific CD8+ and CD4+ T-cells Study goals Rate of regression in patients with primary tumor ≥5cm Timing Preliminary data – Q4 2021/Q1 2022 – Rate of complete response by PET-CT at 6 months and rate of tumor volume reduction by MRI at 30-40 days from start of treatment Trial Sponsor Safety and enhanced efficacy could lead to broad applications of Versamune®-based immunotherapies in combination with chemotherapy or CRT to treat multiple cancers

Studies are designed to demonstrate efficacy and broad applicability of PDS0101 and the Versamune® T-cell activating platform 19 Potential to enhance anti-cancer efficacy of various cancer treatments: Combinations with checkpoint inhibitors, chemotherapy and novel therapies may demonstrate Versamune®’s versatility. Broad potential for additional partnerships: Successful phase 2 studies with PDS0101 and PDS0203 could enable a broad pipeline of Versamune®-based products containing various antigens. Potential to treat all types of HPV-cancer: PDS0101 Phase 2 clinical studies address all types of HPV-associated cancers. Potential applications beyond oncology: PDS0203 COVID-19 phase 1/2 trials may demonstrate protection and induce durable T-cell responses against conserved regions of mutating viruses.

PDS0203 Phase 1/2 Clinical Development

Mt. Sinai data shows Versamune® promotes induction of neutralizing antibodies with lowest doses of SARS-CoV-2 antigen1 21 1Reference: Sun et al. 2020. Vaccines Volume 8, Issue 42Reference: Data on file PDS Biotech generated data shows induction of SARS-CoV-2 specific CD8+ T-cells with Versamune®2 Preclinical studies show powerful induction of long-lasting polyfunctional CD8+ and CD4+ anti-SARS-CoV-2 T-cells Developing a Versamune®-based COVID-19 vaccine candidate with the goal of promoting CD8+ T-cell responses and neutralizing antibodies

Development of PDS0203 may offer potential advantages as a second generation COVID-19 vaccine May be effective against multiple COVID-19 variantsDemonstrated induction of killer CD8+ and helper CD4+ T cells that can target less variable regions of the SARS-CoV-19 virus and may be effective against currently circulating variants.May grant long-lasting immunityDemonstrated induction of long-lasting, virus-specific memory T-cells necessary for longer term protection.High potential for safetyPDS0203 is a subunit vaccine, and does not require the use of attenuated viruses, traditional adjuvants, DNA or RNA. Versamune®-based vaccines have shown no serious or dose limiting reactions. 22
