SPEAKER NOTES (30 sec): Opening: "I'm a patient and a scientist. EoE affects 200,000 Americans, and the therapeutic pipeline is stalled. In one week during the Built with Claude Hackathon, using Claude Science, ESMFold2-Fast, and peer review, we designed an IND-ready multivalent nanoparticle immunotherapy." GRAPHICS: Optional background image (EoE awareness ribbon or nanoparticle schematic outline). Can be added via PowerPoint Insert > Background. ─────────────────────────────────────────────────────────────────────────── SLIDE 2: Disease Burden & Unmet Need ────────────────────────────────────────────────────────────────────────── • 200k EoE patients (1 in 2,000 in Western countries) • Top triggers: Milk (60%), wheat (40%), soy (30%) • Current treatment: Topical steroids + dietary elimination • No approved therapies induce tolerance • Market opportunity: $1–2B (rare disease designation) NARRATIVE: The problem — emotional + economic + clinical urgency. SPEAKER NOTES (45 sec): "EoE is a chronic allergic disease... IL-5/eotaxin-driven eosinophil infiltration... I've lived with this. The dietary restrictions are devastating... no therapy induces durable tolerance... $1–2 billion market opportunity..." GRAPHICS RECOMMENDATION: • Add a simple disease-pathway diagram (IL-5 → eotaxin → eosinophil infiltration) OR • Add a patient quality-of-life infographic (dietary limitations, social impact) OR • Use the magenta/teal color scheme to show prevalence breakdown pie chart HOW TO ADD: 1. In PowerPoint, go to Slide 2 2. Insert > Pictures > choose one of the visualization assets 3. Or create a simple bar chart showing prevalence (1 in 2,000 = ~0.05%) 4.

SPEAKER NOTES (60 sec): "IEDB netMHCIIpan uses neural networks... dairy epitope IC50 16.78 nM is top 1%... validated against published tetramer data... all three are HLA-DRB1*07:01 restricted... Phase 1 will functionally validate wheat/soy... multi-HLA expansion weeks 1–4 gets us to 80%+ coverage..." GRAPHICS: THIS IS WHERE THE THREE EPITOPE CLIPS GO ASSETS: • eoe_pmhc_biotech_clip_dairy.png (c01799f1) • eoe_pmhc_biotech_clip_wheat.png (bdfb3be3) • eoe_pmhc_biotech_clip_soy.png (1baed96f) HOW TO ADD: 1.

Arrange horizontally below the text bullets 5. Add captions: "Dairy", "Wheat", "Soy" 6. These are schematic diagrams showing the epitope + IC50/rank overlaid PRESENTATION TIP: During the pitch, point to each epitope clip and say: "These are schematic representations of the three epitopes we designed. The colors show the binding groove and the epitope core. The numbers overlay IEDB affinity predictions—the lower the IC50, the better the binding." ─────────────────────────────────────────────────────────────────────────── SLIDE 4: Structural Validation & Confidence Metrics ────────────────────────────────────────────────────────────────────────── ✓ Dairy pMHC-II: ipTM 0.872 | pLDDT 0.859 ✓ Wheat pMHC-II: ipTM 0.896 | pLDDT 0.884 ✓ Soy pMHC-II: ipTM 0.891 | pLDDT 0.878 ✓ Single-chain pMHC: pLDDT 0.824 ✓ 15/15 peptide residues in canonical groove ✓ 59–64 of 90 core MHC-peptide contacts NARRATIVE: ESMFold2-Fast validation — ipTM/pLDDT scores, publication-grade. SPEAKER NOTES (45 sec): "ESMFold2-Fast from Biohub predicts protein-protein interactions... ipTM 0.87–0.90 means confident interface predictions... pLDDT 0.85–0.88 means well-folded, low-uncertainty... peptides sit in canonical binding groove... publication-grade, suitable for TCR docking, antibody engineering, mechanism studies..."

Insert > Pictures > add to Slide 4 (right side of text) ─────────────────────────────────────────────────────────────────────────── SLIDE 5: Nanoparticle Platform Architecture ────────────────────────────────────────────────────────────────────────── Core: 20 nm Fe₃O₄ (iron oxide, biodegradable) Surface: ~75 PEG₂ₖ-maleimide linkers (2 nm spacing) Payload: 5 pMHC-II copies per NP Spacing: 5.8 nm inter-epitope (optimal TCR clustering) Avidity: 24× gain from 5-fold multivalency Manufacturing: Precedented protocols (de-risks development) NARRATIVE: Multivalency engineering + manufacturing de-risking. SPEAKER NOTES (60 sec): "A single epitope is good, multivalency is better... five copies on a 20-nanometer iron oxide nanoparticle gives 24× avidity enhancement... iron oxide is biodegradable, off-the-shelf chemistry... published protocols for pMHC-II:Fe₃O₄ conjugation, not novel but proven... three format options: single-chain, NP, tetramer..." GRAPHICS: THIS IS WHERE THE NP ARCHITECTURE SCHEMATIC GOES ASSET: • eoe_np_platform_architecture.png (8138e60d) HOW TO ADD: 1. In PowerPoint, go to Slide 5 2. Insert > Pictures > select eoe_np_platform_architecture.png 3. Size to ~3" x 3" 4. Position on right side of slide 5. Add caption: "20 nm Fe₃O₄ Core with 5 pMHC-II Copies" PRESENTATION TIP: During the pitch, trace your finger across the NP architecture diagram: "Here's the core—iron oxide. Here are the linkers—PEG. Here are the five epitopes spaced 5.8 nanometers apart. That spacing is optimal for TCR clustering. And the multivalency gives us 24× avidity boost—which means even if an epitope's affinity is lower than ideal, the avidity compensates." ─────────────────────────────────────────────────────────────────────────── SLIDE 6: Mechanism — Tr1-Mediated Tolerance Induction ────────────────────────────────────────────────────────────────────────── Hypothesis: Multivalent pMHC-II → Tr1 (CD39+CD73+ IL-10+) differentiation Tr1 expansion suppresses Th2-driven eosinophil recruitment Phase 1: ELISPOT + TCR-Vβ sequencing validation Phase 1 go-gate: Dairy ≥50% IL-10+ responders; wheat/soy ≥30% Phase 2: BALB/c EoE model (eosinophil reduction target ≥40%) Phase 2 efficacy is the critical inflection point NARRATIVE: The mechanistic hypothesis + how Phase 1/2 test it. SPEAKER NOTES (60 sec): "Why would this work? Tr1 cells are regulatory T cells that produce IL-10... multivalent pMHC platforms have shown in published preclinical models— asthma, colitis—that they prime Tr1 differentiation... once you have IL-10-producing Tr1 cells, they suppress the Th2 response that drives eosinophil infiltration... is this proven in EoE? No. Phase 1 and 2 will test it..." GRAPHICS: • Flow cytometry plot showing Tr1 differentiation (CD39+CD73+ IL-10+ gating) • Or a simple immunology schematic: pMHC → TCR → Tr1 → IL-10 → suppressed Th2 HOW TO ADD: 1. Create a simple flow diagram (Tr1 induction pathway) 2. Export as PNG 3. Insert > Pictures > add to Slide 6 4.

SPEAKER NOTES (75 sec): "This roadmap is built from FDA guidance, NIH SBIR rates, CRO quotes, GMP benchmarks... every phase has explicit go/no-go gates... Phase 1, weeks 1 to 14, ex vivo IL-10 validation—$40–65k including Phase 1b in vivo arm... Phase 2, mouse efficacy, BALB/c EoE model... Phase 3, GLP toxicology and 6-month iron oxide biodegradation—FDA requirement... Phase 4, GMP manufacturing, biggest wildcard—if CMO yields are low or device-track CMC inflates, this phase can sink a project... Phase 5, IND dossier + FDA Pre-IND meeting prep... total timeline 84 weeks, 18 to 24 months..." GRAPHICS: THIS IS WHERE THE PRECLINICAL ROADMAP TIMELINE GOES ASSET: • eoe_preclinical_roadmap_timeline.png (218d684c) HOW TO ADD: 1. In PowerPoint, go to Slide 7 2. Insert > Pictures > select eoe_preclinical_roadmap_timeline.png 3. Size to fill most of the slide (below the bullet points) 4. Add caption: "18–24 Month Preclinical Development Timeline" PRESENTATION TIP: During the pitch, walk through the Gantt chart left to right: "Here's Phase 1—14 weeks, 40 to 65 thousand dollars. Here's Phase 2, overlapping manufacturing prep for Phase 3... Phase 3 is the longest, because we need 6-month biodegradation data. Phase 4, manufacturing scale-up. Phase 5, we hit the IND submission target at week 80 to 84, month 18 to 20." ─────────────────────────────────────────────────────────────────────────── SLIDE 8: Regulatory Pathway & IP Position ────────────────────────────────────────────────────────────────────────── ✓ Combination product (biologic + device carrier) → drug-track likely ✓ FDA Pre-IND meeting (month 10–12): Clarify pathway & breakthrough designation ✓ Breakthrough Designation pathway viable (orphan + unmet need + novelty) ✓ IP: Multivalent pMHC-II platform + epitope portfolio (methods-of-manufacture) ✓ Three modality options (single-chain, NP, tetramer) = risk diversification NARRATIVE: Regulatory clarity + IP defensibility. SPEAKER NOTES (50 sec): "Regulatory clarity is critical... is this a drug or device? Combination product, probably drug-track... Pre-IND meeting month 10 to 12 will clarify... breakthrough designation is on the table—orphan indication, unmet need, mechanistic novelty all check the boxes... on IP, we're defending a platform, not a narrow patent... multivalent pMHC-II for tolerance induction, epitope selection methods, NP manufacturing optimization..." GRAPHICS: • FDA regulatory pathway flowchart • Breakthrough Designation timeline HOW TO ADD: 1. Create a simple FDA pathway diagram (question mark → Pre-IND meeting → IND submission → Phase 1) 2. Export as PNG 3. Insert > Pictures > add to Slide 8 ─────────────────────────────────────────────────────────────────────────── SLIDE 9: Competitive Landscape & Market Opportunity ────────────────────────────────────────────────────────────────────────── Current EoE pipeline: Dupilumab (anti-IL-4Rα), steroids, OIT trials Our advantage: Multivalent pMHC-II induce TOLERANCE (novel mechanism) Single-HLA (DR7): 70k patients | Multi-HLA: 160k patients (80%+) Global market: 400k–500k patients (Western countries) Patient-researcher authorship: Authentic rare-disease lens + urgency NARRATIVE: Market opportunity + competitive differentiation. SPEAKER NOTES (50 sec): "What exists now? Dupilumab—approved 2021, anti-IL-4 receptor alpha, suppresses inflammation, doesn't induce tolerance... oral immunotherapy trials for food allergy, not EoE... our advantage is tolerance induction, not symptom suppression... if we work, patients could eat dairy, wheat, soy again without drugs... single-HLA gets 70,000 patients, multi-HLA gets 160,000, 80% of the market... this is not a me-too. This is category-creating." GRAPHICS: • Market size pie chart (single-HLA vs. multi-HLA) • Competitive landscape comparison table (Dupilumab vs. our NP-pMHC) HOW TO ADD: 1. Create a pie chart: 70k (single-HLA) + 130k (multi-HLA) + 0k (non-HLA-targeted) 2. Or create a comparison table showing Dupilumab (symptomatic) vs. NP-pMHC (tolerance-inducing) 3. Export as PNG 4.
