Dr Frank Bedu-Addo, Chief Executive Officer of PDS Biotech, said:

"This past quarter and year have been exciting for PDS Biotech as we have made significant progress on our strategic initiatives and substantial advances in the clinic, including key data and development milestones involving our lead oncology candidate, PDS0101.  We received FDA guidance on the regulatory pathway for the VERSATILE-002 Phase 2 trial and, most recently, the triple combination Phase 2 trial.  We look forward to progressing PDS0101 into a registrational trial in 2023."

Dr Ilian Iliev, CEO of NetScientific, also commented:

"We are delighted with PDS Biotech's continued development, including the exclusive global agreement with Merck KGaA, Darmstadt, Germany to advance the development of PDS0301, and their continued progress in their preclinical oncology candidates and Infectimune™ platform."

Full-Year 2022 Financial Results

Net loss for the year ended December 31, 2022, was approximately $40.9 million, or $1.43 per basic share and diluted share, compared to a net loss of approximately $16.9 million, or $0.66 per basic share and diluted share for the year ended December 31, 2021. The higher net loss was primarily the result of investment in research and development, including the clinical programs and the acquisition of PDS0301.

Research and development expenses for the year ended December 31, 2022, increased to approximately $29.4 million compared to approximately $11.3 million for the year ended December 31, 2021. The increase of $18.2 million was primarily attributable to an increase in personnel costs of $2.3 million, clinical costs of $2.3 million, quality and manufacturing costs of $3.6 million, and $10 million for the rights to PDS0301 from Merck KGaA, Darmstadt Germany. Of the $10 million paid to Merck KGaA, Darmstadt Germany, $5 million was in cash and the balance in shares of the Company's common stock.

General and administrative expenses for the year ended December 31, 2022, increased to approximately $12.2 million compared to approximately $10.2 million for the year ended December 31, 2021. The $2.0 million increase was primarily attributable to an increase in personnel costs of $1.3 million and an increase in professional fees of $0.7 million.

Total operating expenses for the year ended December 31, 2022, were approximately $41.7 million, an increase of approximately 94% compared to total operating expenses of approximately $21.4 million for the year ended December 31, 2021.

The Company's cash balance as of December 31, 2022, was $73.8 million. Based on the Company's available cash resources and cash flow projections, the Company believes that with the anticipated initiation of one registrational trial in 2023, this balance is sufficient to fund Company operations and research and development programs into the third quarter of 2024.

About PDS Biotechnology 

PDS Biotechnology is a clinical-stage immunotherapy company developing a growing pipeline of targeted cancer and infectious disease immunotherapies based on our proprietary Versamune^®, PDS0301, and Infectimune™ T cell-activating platforms. We believe our targeted Versamune^® and PDS0301 based candidates have the potential to overcome the limitations of current immunotherapy approaches through the activation of the right type, quantity and potency of T cells. To date, our lead Versamune^® clinical candidate, PDS0101, has demonstrated the ability to reduce tumours and stabilize disease in combination with approved and investigational therapeutics in patients with a broad range of HPV16-associated cancers in multiple Phase 2 clinical trials. Our Infectimune™ based vaccines have also demonstrated the potential to induce not only robust and durable neutralizing antibody responses, but also powerful T cell responses, including long-lasting memory T cell responses in pre-clinical studies to date.
