Introduction to the Versamune® Platform
Versamune® is designed to induce a robust and targeted anti-tumor response in vivo when administered with a tumor-associated
antigen 7 Reference: Gandhapudi SK, et al. 2019. Antigen priming with enantiospecific cationic lipid nanoparticles induces potent antitumor CTL responses through novel induction of a Type I IFN response. J Immunol. 202 (12): 3524-3536.Smalley
Rumfield C et al.. 2020. Immunomodulation to enhance the efficacy of an HPV therapeutic vaccine. J. for ImmunoTherapy of Cancer 8:e000612. Promotes uptake of vaccine or immunotherapy and entry into lymph nodes Promotes antigen processing
and presentation to T-cells via MHC I and II pathways Activates Type I Interferon pathway, enabling a powerful anti-tumor killer CD8+ T-cell response Versamune® + Tumor-associated proteins (antigens)
Greater quantity and quality of Versamune®-induced killer T-cells may result in unique ability to eradicate HPV-positive tumors after a
single dose 8 Induced a >10-fold number of highly potent T-cells and eradication of HPV-positive tumors after a single dose Single treatment dose Results typical of current topclinical-stage HPV cancer vaccines Tumor rechallenge at Day

PDS0101 Phase 2 Clinical Development
15 PDS0101 is designed to treat cancers caused by human papillomavirus (HPV) Approximately 43,000 patients are diagnosed with
HPV-associated cancers annually in the USIncidence rate is growing despite increased use of HPV preventative vaccinesSignificant unmet medical need across the spectrum of HPV-associated cancerExisting immunotherapies cost $120,000+ annually per
patient2 1Markowitz et al. 2016. Centers for Disease Control and Prevention. 2018.2Hernandez et al. 2018. American Journal of Managed Care Volume 24, Issue 2; Company Research Females (24,391) Males (18,280) US annual HPV-associated cancer

Combinations of PDS0101 with FDA-approved standard of careFirst line treatment of recurrent/metastatic HPV-positive head and neck
cancerCombination with Keytruda®Treatment of advanced localized cervical cancerCombination with chemoradiotherapy 16 Novel combinations of PDS0101 with promising immunotherapeutic agentsTreatment of advanced HPV-associated cancers (anal,
cervical, vaginal, head and neck etc.)Triple combination with Bintrafusp-alpha (bi-functional checkpoint inhibitor - M7824) and NHS-IL12 (antibody conjugated immuno-cytokine) Clinical strategy to evaluate improved therapy: Combine PDS0101 with
established therapies for rapid proof-of-concept and risk mitigation
Phase 2 investigator-initiated clinical trial evaluating the combination of PDS0101, M7824 and NHS-IL12 in advanced HPV-associated
cancer 17 Indication Patients with advanced HPV-associated cancer who have failed prior treatment Clinical Agents M7824: Bifunctional fusion protein - checkpoint inhibitor + TGF-b “TRAP” (ORR ~30%)NHS-IL12: Antibody-conjugated

advanced cervical cancer Indication Treatment of patients with locally advanced cervical cancer – Stages IB3-IVA Clinical Agents Chemoradiotherapy (CRT – Standard of Care): Cisplatin & radiation therapyPDS0101: Versamune®-based
immunotherapy generating HPV-specific CD8 and CD4 T-cells Study goals Rate of regression in patients with primary tumor ≥5cm Timing Preliminary data – Q4 2021/Q1 2022 – Rate of complete response by PET-CT at 6 months and rate of tumor
volume reduction by MRI at 30-40 days from start of treatment Trial Sponsor Safety and enhanced efficacy could lead to broad applications of Versamune®-based immunotherapies in combination with chemotherapy or CRT to treat multiple cancers
Studies are designed to demonstrate efficacy and broad applicability of PDS0101 and the Versamune® T-cell activating
platform 20 Enhance anti-cancer efficacy of various cancer treatments: Combinations with checkpoint inhibitors, chemotherapy and novel therapies may demonstrate Versamune®’s versatility. Broad partnerships: Successful phase 2 studies with
PDS0101 and PDS0203 could enable development of a broad pipeline of Versamune®-based products containing various antigens. Potential to treat all types of HPV-cancer: PDS0101 Phase 2 clinical studies address all types of HPV-associated
cancers. Applications beyond oncology: PDS0203 COVID-19 phase 1/2 trials may demonstrate powerful preventive ability and induce durable T-cell responses against conserved regions of mutating viruses.
Looking Forward
Financial position to support PDS0101 projected milestones through mid-2022* 22 *Based on current enrollment and forecast modeling as
of November 2020. Subject to change.
Positioned for accelerated development 23 Enhanced anti-cancer efficacy: Early clinical data and preclinical data suggest potentially
superior efficacy, safety and versatility of the platformNear-term milestone: PDS0101 preliminary data Q1-Q2 2021Validation of approach: All three on-going phase 2 clinical trials supported and partnered with leading and top-tier institutions
in the field of cancer and immuno-oncologyCommercialization path: Clinical studies evaluating the potential to safely enhance the clinical efficacy of FDA-approved anti-cancer products presents a potentially rapid path to commercializationRapid
