9:00 am Leveraging Immunopeptidomics to Validate Endogenous Antigen Presentation & De-Risk Epitope Selection

  • Roy de Souza Co-Founder & Chief Executive Officer, BreakBio

Synopsis

• Using mass spectrometry-based immunopeptidomics to directly identify MHC-bound peptides from tumor tissue to confirm which predicted antigens are truly presented

• Detecting post-translationally modified, cryptic, or low-abundance peptides that escape standard analysis to overcome predictive blind spots

• Incorporating immunopeptidomics into early discovery workflows to de-risk antigen selection, reduce false positives, and support regulatory confidence in epitope relevance

9:30 am Session Reserved for Twist Bioscience

10:00 am Activating the Immune System With Whole-Tumor Vaccines: Harnessing Shared & Neoantigens to Remodel the Tumor Microenvironment

  • Ray Goodrich Chief Scientific Officer/Vice President of R&D, PhotonPharma

Synopsis

• Leveraging whole tumor cells as antigen-presenting tools to stimulate immune responses effectively

Neoantigen Strategy: Solving the Prediction–Validation Gap to Identify Potent, Patient- Specific Targets That Accelerate Clinical Success & Enable Scalable Manufacturing

11:30 am Expanding the Neoantigen Strategy Beyond Melanoma: Evolving Target Selection Across Tumor Types to Expand PCV Applicability

Synopsis

• Translating lessons from V940 to inform indication expansion and optimize antigen design across tumor types with differing immune responsiveness

• Validating evolving antigen strategies in early-stage settings to accelerate clinical translation and enable faster access

• Navigating regulatory considerations to determine when antigen selection strategy constitutes a new product vs an extension of platform intent

12:00 pm Session Reserved for Eclipse Bio

12:30 pm Nanofilament-Directed Immunotherapy Ignites Robust Antitumor Vaccine Responses & Overcomes Neoantigen Prediction Bottlenecks

Synopsis

• Bioengineered nanofilaments bypass the need to map individual neoantigens by directly converting cancer cells into targets for the immune system

• Nanofilament biologic activities orchestrate the immune response – from tumor antigen capture to T-cell activation

• Nanofilament-Directed Immunotherapy offers an off-the-shelf solution to ignite a robust antitumor vaccine response against the patient’s complete tumor antigen repertoire

1:00 pm Lunch Break

Decode the Tumor, Design the Cure: Prioritizing Indications, Overcoming Immune Barriers, & Visualizing the Tumor Microenvironment to Build Better PCVs

2:00 pm Using ctDNA & Immune Biomarkers to Capture Dynamic Tumor Biology, Monitor Treatment Response, & Guide Smarter Vaccine Design

  • Jian Yan Vice President - Research & Discovery, Geneos Therapeutics, Inc.

Synopsis

• Using ctDNA as a biomarker to monitor treatment response

• Harnessing ctDNA to fine-tune vaccine design based on evolving tumor profiles for reducing clinical failure

• Using biomarker signatures like CD80, PD-L1, and CD4/CD8 ratios to assess immunogenic potential and stratify patients most likely to benefit from PCVs

• Translating dynamic tumor insights into actionable design pivots to optimize a durable response

2:30 pm Using the Patient’s Own Tumor to Eliminate Neoantigen Prediction & Redesign Clinical Trials

Synopsis

• Deploying a unique mechanism that bypasses complex neoantigen prediction by letting the patient’s own tumor drive antigen presentation, eliminating the need for upfront epitope mapping

• Cutting manufacturing costs and compressing turnaround to just three weeks by growing tumor-derived cells directly to avoid extensive sequencing, synthesis, and custom design

• Targeting patients with minimal residual disease and healthy immune systems to maximize vaccine response, moving beyond late-stage metastatic settings where immune function is severely compromised

• Incorporating adjuvant strategies that strengthen immune activation earlier in the disease course, improving the odds of durable remission

3:00 pm Roundtable: Determining Optimal Duration of Cancer Vaccine Therapy to Maximize Immune Durability, Minimize Patient Burden, & Improve Long- Term Outcomes

  • Joann Peters Chief Operating Officer, Geneos Therapeutics, Inc.

Synopsis

• How to define the right length of vaccine administration in advanced and adjuvant settings to maximize durable immune responses and reduce relapse risk

• How to weigh the trade-offs between prolonged treatment and patient quality of life to avoid unnecessary long-term psychological burden

• How to tailor duration strategies by modality (RNA, DNA, peptides) to minimize side effects and achieve sustained clinical benefit
