Clinical Trials: PDS Biotech is conducting the only ongoing registrational trial (VERSAL-three) specifically targeting HPV16 positive head and neck cancer, which is a significant and growing medical problem [17][44] 2. Prognosis: HPV16 positive patients have a worse prognosis compared to P16 positive patients, with studies indicating that HPV16 positive patients may have survival rates similar to HPV negative patients [16][30] 3. Survival Data: The VERSAL-two trial reported a median overall survival (MOS) of 30 months for HPV16 positive patients, which is significantly better than the published results for other treatments [19][20] 4. Treatment Mechanism: Versamune HPV is designed to generate T cells that specifically target E6 and E7 proteins of HPV16, which are integrated into tumor DNA, providing a robust treatment approach for this patient population [32] 5. Regulatory Considerations: The FDA has requested a companion diagnostic to confirm HPV16 positive patients for enrollment in the VERSAL-three trial, emphasizing the need for accurate patient identification [23][32] Additional Important Insights - Confusion in Terminology: There is ongoing confusion between P16 positive and HPV16 positive classifications, which complicates treatment discussions and patient management [52][54] - Competitive Landscape: Other ongoing trials have shown better responses in HPV negative patients compared to HPV positive patients, highlighting the challenges in treating HPV16 positive cases [54] - Recruitment Strategy: The specificity of the HPV16 positive population has aided in the recruitment of clinical sites for the VERSAL-three trial, with oncologists expressing a preference for enrolling HPV16 positive patients in this study [41][48] Conclusion - PDS Biotech is positioned to address a significant unmet need in the treatment of HPV16 positive head and neck cancer through its innovative immunotherapy approach, with promising clinical data supporting its efficacy and ongoing trials aimed at improving patient outcomes [57][58]
