Furthermore, we continue to develop our novel antibody-conjugated IL-12 asset PDS0301 and look forward to providing an update on ongoing investigator-initiated Phase 2 trials at the NCI in several solid tumor indications.”

First Quarter 2022 Financial Results
Reported net loss was approximately $9.7 million, or $0.32 per basic share and diluted share, for the three months ended March 31, 2023, compared to a net loss of $8.5 million, or $0.32 per basic share and diluted share, for the three months ended March 31, 2022. The increase was due to personnel, clinical studies, medical affairs, and manufacturing expenses.

Research and development expenses increased to approximately $5.8 million for the three months ended March 31, 2023, from $5.2 million for the three months ended March 31, 2022. The increase of $0.6 million in 2023 was primarily attributable to an increase of $0.2 million in clinical studies and medical affairs, $0.8 million in personnel costs and $0.1 million in professional fees offset by a decrease of $0.5 million in manufacturing expenses.

General and administrative expenses increased to approximately $3.6 million for the three months ended March 31, 2023, from approximately $3.3 million for the three months ended March 31, 2022. The increase of $0.3 million is primarily attributable to an increase of $0.8 million in personnel, which is offset by a decrease of $0.5 million in professional fees.

Total operating expenses increased to approximately $9.4 million for the three months ended March 31, 2023 from $8.5 million for the three months ended March 31, 2022.

Cash and cash equivalents as of March 31, 2023, totaled approximately $65.2 million. Based on the Company’s cash resources with the anticipated initiation of one registrational trial in 2023, PDS Biotech believes this balance is sufficient to fund the Company’s operations and research and development programs into the third quarter of 2024.

About PDS Biotechnology
PDS Biotech is a clinical-stage immunotherapy company developing a growing pipeline of targeted cancer and infectious disease immunotherapies based on our proprietary Versamune^®, Versamune^® plus PDS0301, and Infectimune™ T cell-activating platforms and PDS0301 tumor targeting immunocytokine. We believe our targeted immunotherapies 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 tumors 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. and will be advancing into a Phase 3 clinical trial in combination with KEYTRUDA^® for the treatment of recurrent/metastatic HPV16-positive head and neck cancer in 2023. 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.
