“The third quarter has been monumental for PDS Biotech, and we continue to make strides towards commercialization of our lead candidate, PDS0101,” stated Dr. Frank Bedu-Addo, President and Chief Executive Officer of PDS Biotech. We’ve remained focused on progressing our four Phase 2 clinical programs, most recently, announcing data from our IMMUNOCERV trial in locally, advanced cervical cancer. 100% (9/9) of patients had a clinical response with tumor shrinkage of over 60% at the midpoint evaluation, and 89% (8/9) of patients had a complete response with no evidence of disease at day 170, when treated with a combination of PDS0101 and chemotherapy. Furthermore, we released expanded interim data from our NCI-led PDS0101-based triple combination trial demonstrating 66% (19/29) survival at median follow up of 16 months in checkpoint inhibitor refractory HPV-positive cancer patients that appears to show signs of clinical efficacy, durability, and safety, consistent with the data presented at the American Society for Clinical Oncology 2022. And, with VERSATILE-002 in which PDS0101 is combined with KEYTRUDA^®, we are preparing for a registrational trial after our successful end-of-Phase 2 meeting with the FDA. To date, we have presented PDS0101 Phase 2 efficacy data in over 60 patients and safety data in over 100 patients.” 

Matthew Hill, Chief Financial Officer of PDS Biotech, stated, “We are excited about the progress we have made in our development programs, and we have strengthened the balance sheet to support our ongoing efforts. This August, we increased our cash position by entering into a loan agreement with Horizon Technology Finance Corporation, where we received an initial tranche of $25 million in term loans. This financing provides PDS Biotech with the financial resources and runway needed to prepare for a registrational trial for our lead candidate, PDS0101, and to advance our preclinical pipeline.”

Third Quarter 2022 Financial Results
Net loss for the three months ended September 30, 2022 was approximately $7.4 million, or $0.26 per basic share and diluted share, compared to a net loss of approximately $7.0 million, or $0.24 per basic and diluted share, for the three months ended September 30, 2021. The higher net loss reported for the three months ended September 2022 is primarily due to additional costs for expansion of the Company’s research and development, including costs associated with our ongoing clinical trials and additional general and administrative costs.

Research and development expenses increased to $4.4 million for the three months ended September 30, 2022 from $3.7 million for the three months ended September 30, 2021. The increase of $0.7 million in 2022 was primarily attributable to an increase of $0.2 million in clinical study and research costs, $0.3 million in personnel costs and $0.4 million in manufacturing services partially offset by a decrease of $0.2 million in professional fees and facilities.

General and administrative expenses decreased to $2.9 million for the three months ended September 30, 2022 from $3.3 million for the three months ended September 30, 2021. The decrease of $0.4 million is primarily attributable to a decrease of $0.5 million in personnel an increase of $0.2 million in professional fees partially offset by a decrease of $0.1 million in facilities costs.

Total operating expenses were approximately $7.3 million for the three months ended September 30, 2022, from approximately $7.0 million for the three months ended September 30, 2021.

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^® and Infectimune™ T cell-activating technology platforms. We believe our targeted Versamune^® based candidates have the potential to overcome the limitations of current immunotherapy by inducing large quantities of high-quality, potent polyfunctional tumor specific CD4+ helper and CD8+ killer T cells. To date, our lead Versamune^® clinical candidate, PDS0101, has demonstrated the potential to reduce tumors and stabilize disease in combination with approved and investigational therapeutics in patients with a broad range of HPV-positive 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.
