Exhibit 99.1

PDS Biotech Reports Financial Results for the Year Ended December 31, 2020 and Provides Business Update

Florham Park, NJ, March 18, 2021 - 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, today announced its financial results for the year ended December 31, 2020 and provided a business update.

Recent Business Highlights:

● Achieved preliminary efficacy benchmark in the Phase 2 combination trial of PDS0101 led by the National Cancer Institute.

● Initiated VERSATILE-002, a Phase 2 trial of lead investigational drug candidate PDS0101, in combination with standard of care KEYTRUDA^® for first-line treatment of patients with metastatic or recurrent HPV-positive head and neck cancer.

● Phase 2 trial of lead investigational drug candidate PDS0101, in combination with standard of care chemoradiotherapy for patients with advanced cervical cancer was initiated by the University of Texas MD Anderson Cancer Center.

● Expanded consortium for development of PDS0203, a novel, Versamune^®-based second-generation COVID-19 vaccine to include Blanver Farmoquímica in addition to Farmacore.

● Received award commitment of up to $60 million from Brazil’s Ministry of Science, Technology and Innovation (MCTI) to fund clinical development and commercialization of PDS0203.

● Strengthened leadership team with the appointment of Seth Van Voorhees as Chief Financial Officer and addition of preeminent oncologist Otis Brawley, M.D. to the board of directors.

“Despite the challenges of 2020, the PDS Biotech team remained focused on the advancement of our Versamune^®-based drug pipeline,” commented Dr. Frank Bedu-Addo, President and Chief Executive Officer of PDS Biotech. “Through that commitment and the strength of our partnerships with leading institutions in the fields of immuno-oncology and infectious disease, we made significant strides in solidifying the safety profile and establishing the efficacy of our Versamune^® platform and products as we continue to progress our portfolio towards commercialization.”

Full Year 2020 Financial Results

For the year ended December 31, 2020, the net loss was approximately $14.8 million, or $0.89 per basic share and diluted share, compared to a net loss of approximately $7.0 million, or $1.44 per basic share and diluted share for the year ended December 31, 2019.

For the year ended December 31, 2020, research and development expenses increased to $7.9 million compared to $6.1 million during the prior year. The increase was primarily the result of increased expenses related to manufacturing and personnel costs for the ongoing clinical studies.

For the year ended December 31, 2020, general and administrative expenses decreased to $7.0 million compared to $11.0 million during 2019. The $4.0 million decrease was due to decreases in personnel costs of $0.4 million, non-cash stock-based compensation of $2.4 million, D&O insurance costs of $0.5 million, legal fees of $0.5 million and professional fees of $0.2 million.

Total operating expenses for 2020 were $14.9 million, a decrease of approximately 29% compared to $21.0 million during the prior year.

The company’s cash balance as of December 31, 2020 was $28.8 million.
