3 PDS Biotech’s Versamune®-based immunotherapies promote a powerful in vivo tumor-specific CD8+
killer T-cell response Generate a strong CD8+ T-cell memory response resulting in long-lasting efficacy Are versatile and shown to be effective on their own or in combination with other drugs to improve their efficacy Generate potency
without systemic side effects The most significant barrier to effective immunotherapy has been their inability to promote adequate CD8+ killer T-cell responses in vivo resulting in diminished efficacy Versamune®-based therapies also:

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 8 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 9 Induced a >10-fold number of highly potent T-cells and eradication of HPV-positive tumors after a single dose in preclinical studies Single treatment dose Results typical of current
topclinical-stage HPV cancer vaccines Tumor rechallenge at Day 60; complete and sustained cure of cancer *Adjuvant = cytokine GMCSFReferences: J. Immunology, 2019 (202), 1215; Studies in TC-1 tumor model with other immunotherapies

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 13 Novel combinations of PDS0101 with promising, investigational 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:
Develop PDS0101 in combination 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 14 Indication Patients with advanced HPV-associated cancer who have failed prior treatment Clinical Agents Bintrafusp alfa (M7824): Bifunctional “trap” fusion protein (ORR ~30%)M9241 (NHS-IL12):
Antibody-conjugated immuno-cytokinePDS0101: Versamune®-based immunotherapy generating HPV-specific CD8+ T-cells Study goals Group 1: Objective response rate (ORR) in checkpoint inhibitor (CPI) naïve patientsGroup 2: ORR in patients who have
failed checkpoint inhibitor therapy (CPI refractory) Timing Full enrollment of 45 patients triggered following achievement of objective response in ≥ 3 checkpoint inhibitor naive patientsTrial completion expected in Q1 2022 Trial
Sponsor Confirmation that PDS0101 enhances the therapeutic benefit of Bintrafusp alfa and M9241 may lead to expanded evaluation in several cancers with PDS0102, PDS0103 and PDS0104

10.1136/jitc-2020-000612 In a preclinical model, PDS0101 demonstrated enhanced ability to train tumor-specific T-cells to be effective in infiltrating and killing tumors Red – CD8+ (killer) T-cellsGreen – CD4 + (helper) T-cells T-cell
clones per 25% of TCR repertoire (Average) Combination of PDS0101 with M9241 or Bintrafusp alfa generated superior targeted T-cell response; triple combination demonstrated superior efficacy
Relapsed or refractory advanced HPV-related cancer presents a high bar for evaluation and significant
unmet medical needPatients who fail chemotherapy and/or radiation progress to checkpoint inhibitor therapy12-24% reported efficacy of standard of care checkpoint inhibitorsAn experimental immunotherapy (Bintrafusp alfa) has reported the
highest ORR to date in advanced HPV-associated cancer patients who are checkpoint inhibitor naive of 30%Few treatment options exist for patients who have also failed checkpoint inhibitor therapy The experimental immunotherapy (Bintrafusp
alfa) has demonstrated an ORR of 10% reported in advanced HPV-associated checkpoint inhibitor refractory cancer PDS0101 phase 2 triple combination trial: evaluates observation of superior preclinical tumor regression in advanced HPV-related
cancer 16 The most critical limitation of immunotherapy is the inability to induce large numbers of powerful tumor-attacking CD8+ (killer) T-cells within the body, that can result in tumor reduction or elimination in a significant number of
advanced cancer patients Strauss J, et al. J Immunother Cancer. 2020 Dec;8(2):e001395
17 PDS Biotech-sponsored phase 2 trial evaluating the combination of PDS0101 and KEYTRUDA for
first-line treatment of HPV-associated metastatic/recurrent head and neck cancer Indication First line treatment of patients with HPV-associated head and neck cancer whose cancer has spread or returned Clinical Agents KEYTRUDA (Standard
of Care): Anti-PD1 checkpoint inhibitor (ORR ~20%)PDS0101: Versamune®-based immunotherapy generating HPV-specific CD8+ and CD4+ T-cells Study goals Objective response rate (ORR) and overall survival (OS) Timing Preliminary data – Q4
2021/Q1 2022, ORR in first 20 patients (efficacy in 7 of 38 required to enroll all 96 patients) Trial Partner Confirmation that PDS0101 enhances the therapeutic benefit of checkpoint inhibitors could expand evaluation of Versamune®-based
therapies in multiple cancer indications
18 A Phase 2, investigator-initiated clinical trial evaluating PDS0101 in combination with
chemoradiation therapy in patients with 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 19 Potential to enhance anti-cancer efficacy of various cancer treatments: Combinations with checkpoint inhibitors, chemotherapy and novel therapies may demonstrate Versamune®’s versatility. Broad potential for
additional partnerships: Successful phase 2 studies with PDS0101 and PDS0203 could enable 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. Potential applications beyond oncology: PDS0203 COVID-19 phase 1/2 trials may demonstrate protection and induce durable T-cell responses against conserved regions of mutating viruses.
PDS0203 Phase 1/2 Clinical Development
Mt. Sinai data shows Versamune® promotes induction of neutralizing antibodies with lowest doses of
SARS-CoV-2 antigen1 21 1Reference: Sun et al. 2020. Vaccines Volume 8, Issue 42Reference: Data on file PDS Biotech generated data shows induction of SARS-CoV-2 specific CD8+ T-cells with Versamune®2 Preclinical studies show powerful
induction of long-lasting polyfunctional CD8+ and CD4+ anti-SARS-CoV-2 T-cells Developing a Versamune®-based COVID-19 vaccine candidate with the goal of promoting CD8+ T-cell responses and neutralizing antibodies
Development of PDS0203 may offer potential advantages as a second generation COVID-19 vaccine May be
effective against multiple COVID-19 variantsDemonstrated induction of killer CD8+ and helper CD4+ T cells that can target less variable regions of the SARS-CoV-19 virus and may be effective against currently circulating variants.May grant
long-lasting immunityDemonstrated induction of long-lasting, virus-specific memory T-cells necessary for longer term protection.High potential for safetyPDS0203 is a subunit vaccine, and does not require the use of attenuated viruses,
traditional adjuvants, DNA or RNA. Versamune®-based vaccines have shown no serious or dose limiting reactions. 22
