Thank you, operator. Good morning, everyone, and welcome to PDS Biotech's 2024 results and clinical program update call. I'm joined in the calls today by the following members of the company's management team Dr. Frank Bedu Addo, Chief Executive Officer, Dr. Kirk Shepard, Chief Medical Officer, and Lars Boesgaard, Chief Financial Officer.

Frank Bedu-Addo

Thank you, Tom. And good morning, everyone.
It's our pleasure to speak with you again and to provide this brief update on our progress in advancing our clinical programs 2024 and the first weeks of 2025 have been busy and productive.
Led by the initiation of our VERSATILE-003 phase 3 clinical trial of Versamune HPV plus Pembrolizumab compared to Pembrolizumab as a potential treatment for first-line recurrent and or metastatic HPV16 positive head and neck squamous cell carcinoma, HNSCC or head and neck cancer.
Patients with HPV16 positive head and neck cancer represent a large, fast-growing population in need of targeted therapies to treat the underlying cause of the cancer. It is projected that by the mid-2030s, HPV16 positive head and neck cancer could be the most prevalent type of head and neck cancer in the United States and Europe.
Considering the strength and durability of the clinical responses observed in our VERSATILE-002 phase 2 study, we are pleased to get this registrational trial underway and are confident in the potential of our innovative combination of Versamune HPV and Pembrolizumab to improve patient outcomes and enhance the standard of care.
In the coming weeks, we expect to continue to activate additional clinical sites and look forward to the continued progression of this trial. As we announced previously, the VERSATILE-003 trial design includes approximately 350 patients. The two-arm registrational trial design has been given the go ahead by the US Food and Drug Administration (FDA).
The two arms of the trial include a treatment arm of the verse immune HPV Pembrolizumab combination versus the control arm of Pembrolizumab only. Patients are enrolled in a 2:1 randomization.
Median overall survival is the primary endpoint. The trial design is informed by the observed durability of the clinical responses in our VERSATILE-002 phase 2 clinical trial seen over the last year with the most recent data presented at the European Society for Medical Oncology ESMO Congress in September.
These data demonstrated the following. Median overall survival has remained at 30 months over the last two data cuts, and the lower limit of the 95% confidence interval improved to approximately 20 months. The best published median overall survival for Pembrolizumab is 17.9 months.
Promising durability and long-lasting anti-tumor immune responses were demonstrated with improvement in all clinical response outcomes between the data presented in June of 2023 at the American Society of Clinical Oncology ASCO conference and September of 2024 at ESMO, a period of a little over a year.
Objective response rate improved from 26% to 36%. Published objective response rate for Princeton map is 19% to 25%. Disease control rate improved from 70% to 77%. The number of patients with complete or near complete responses of 90% to 100% tumor shrinkage increased from 6% to 21%. The number of patients with complete responses increased from 3% to 9%.
The most common treatment-related adverse events overall were grade 1 and grade 2 transient injection site reactions. Treatment-related adverse events of grade 3 and higher were seen in 9 out of 87 patients or 10% of immune checkpoint inhibitor naive and immune checkpoint inhibitor resistant patients in the trial.
There was only one grade 4 treatment-related adverse event. The encouraging patient survival and clinical responses coupled with promising tolerability as seen in the VERSATILE-002 clinical trial underscores our belief in the potential of the combination to be the first HPV targeted immunotherapy for head and neck cancer and a significant advancement in the treatment of the growing population of patients with HPV16 positive head and neck cancer.
Elsewhere in our pipeline, we were pleased to announce FDA clearance of our investigational new drug IND application for the combination of Versamune MUC1 and PDS01ADC to treat metastatic colorectal cancer. This is a significant development for the company, as several highly prevalent solid tumors are Mach one positive, including non-small cell lung cancer, ovarian cancer, breast cancer, liver cancer, and others.
We are pleased to announce that we continue our strong relationship with the National Cancer Institute, and this phase 12 clinical trial is scheduled to be run under our collaborative research and development agreement with the National Cancer Institute.
PDS Biotech will continue to focus our efforts on progressing the VERSATILE-003 phase 3 clinical trial. Last October, data from our IMMUNOCERV phase 2 clinical study evaluating verse immune HPV with chemo radiation to treat locally advanced cervical cancer were presented at the American Society for Radiation Oncology (ASTRO) annual meeting.
The presented data demonstrated promising survival, clinical activity, and a compelling safety profile. Based on research and continued in various HPV positive cancers conducted by PDS Biotech and by independent researchers who recognize its potential, Versamune HPV appears to work in combination with a variety of therapeutic agents to generate clinical responses and promote improved survival in patients with a favorable safety profile.
Also last October, the rationale and trial design for the National Cancer Institute led study evaluating our IL-12 fused antibody drug conjugate PDS01ADC in combination with [Austeussenzulattamide] versus enzalutamide alone for the treatment of recurrent prostate cancer was discussed during an oral presentation. At the 12th annual meeting of the International Cytokine and Interference Society Cytokines 2024 in Seoul, South Korea.
The presentation was given by Ravi A. Madan, M.D, Head, Prostate Cancer Clinical Research Section, Genitourinary Malignancies Branch, Center for Cancer Research, National Cancer Institute, part of the US National Institutes of Health.
Now, I will turn it over to Lars for a review of our results for 2024.
