Status: REVISED MANUSCRIPT READY FOR SCIENCE SUBMISSION

================================================================================
PEER REVIEW RECOMMENDATIONS ADDRESSED
================================================================================

All three reviewers (Structural Biology, Biotech, Regulatory) recommended:
PROCEED TO PHASE 1 WITH SPECIFIED CAVEATS

LIGHT REVISIONS IMPLEMENTED:

1. WHEAT & SOY EPITOPE VALIDATION (Reviewer 1 & 3 concern)
   ✓ Added conditional language: "epitope selection is conditional on Phase 1 
     functional validation"
   ✓ Specified Phase 1b parallel readout: compare reframed vs. original disulfide 
     frame to assess whether affinity penalty compromises immunogenicity
   ✓ Clarified: "Like wheat, soy epitope efficacy is pending Phase 1 functional 
     validation before Phase 2 efficacy claims are made"
   
   Impact: Positions manuscript as rigorous and transparent about unknowns; 
   strengthens credibility with FDA reviewers.

2. PHASE 1 DESIGN EXPANSION (Reviewer 3 recommendation)
   ✓ Phase 1 budget INCREASED: $20–35k → $40–65k (reflects Phase 1b in vivo arm)
   ✓ Phase 1 timeline INCREASED: Weeks 1–12 → Weeks 1–14
   ✓ Phase 1b ARM ADDED: n=5–10 patients, single-dose IV NP-pMHC-II, esophageal 
     biopsy days 7 and 28 for in vivo eosinophil reduction + proof-of-mechanism
   ✓ Justification added: "This exploratory arm strengthens IND narrative and 
     breakthrough designation eligibility"
   
   Impact: Addresses all three reviewers' concern that Phase 1a (ex vivo only) 
   lacks in vivo proof-of-mechanism; enhances FDA Pre-IND positioning.

3. MULTI-HLA EXPANSION AS CRITICAL PATH (All reviewers flagged as essential)
   ✓ Elevated to prominent "CRITICAL ACTION ITEM" section
   ✓ Specified timeline: Weeks 1–4, parallel to Phase 1 IND preparation
   ✓ Linked to regulatory pathway: "FDA Pre-IND meeting will require multi-HLA 
     roadmap"
   ✓ Enumerated consequences of multi-HLA portfolio:
     • Phase 1 IND language ("planned multi-HLA pipeline")
     • Phase 1b patient stratification by HLA responder
     • Phase 2 IND population coverage ≥70%
     • Breakthrough designation pathway support
     • Biotech licensing conversations (expanded addressable market)
   
   Impact: Demonstrates awareness of commercial landscape and regulatory 
   expectations; positions multi-HLA work as essential first step, not 
   afterthought.

4. LONG-TERM SAFETY EMPHASIS (Reviewer 3 FDA precedent concern)
   ✓ Phase 3 extended biodegradation now framed as "critical for Phase 1b IND 
     approval"
   ✓ Specified FDA requirement: 6–12 month preclinical data to support in vivo 
     arm
   ✓ Discussion section emphasizes: "Phase 3 extended biodegradation studies 
     (Prussian blue + ICP-AES) are essential to support Phase 1b in vivo dosing 
     and Phase 2 repeat-dosing"
   
   Impact: Demonstrates regulatory sophistication and prevents late-stage 
   surprises in FDA Pre-IND meeting.

MANUSCRIPT CHANGES SUMMARY (BY SECTION)
================================================================================

ABSTRACT:
  • Updated Phase 1 cost: $20–35k → noted in combined preclinical budget
  • Added Phase 1b language: "exploratory in vivo functional validation"
  • Emphasized multi-HLA: "critical regulatory pathways (FDA Pre-IND, multi-HLA 
    expansion weeks 1–4, long-term iron safety)"

INTRODUCTION:
  • No major changes; logic flow intact

RESULTS:
  
  Section 1 (Epitope Discovery):
    • Dairy: 90-fold → ~92-fold (1535.53 / 16.78 = 91.51)
    • Added to wheat: conditional Phase 1 validation language
    • Added to soy: conditional Phase 1 validation language
  
  Section 5 (Preclinical Roadmap):
    • PHASE 1 RESTRUCTURED:
      - Phase 1a (Ex vivo, $20–35k): recruitment, IL-10 ELISPOT, TCR readouts
      - Phase 1b (In vivo, +$20–30k): n=5–10 patients, single-dose IV, biopsy 
        days 7/28, esophageal eosinophil reduction readout
      - Timeline: Weeks 1–14 (was 1–12)
      - Total Phase 1 budget: $40–65k
    • PHASE 2–5: Budget reconciled ($35–55k, $105–170k, $80–140k, $15–27k)
    • Grand total: $275–457k (Phase 1 increase of $20k on both bounds cascaded)
  
  Section 6 (Multi-HLA Expansion):
    • ELEVATED TO "CRITICAL ACTION ITEM" (was subordinate mention)
    • Added FDA context: "Pre-IND meeting will require multi-HLA roadmap"
    • Enumerated regulatory/commercial benefits (5 bullet points)
    • Linked to breakthrough designation pathway

DISCUSSION:
  • Updated dairy fold-change: 90-fold → ~92-fold
  • Emphasized wheat/soy conditionality: "Phase 1 functional validation"
  • Reinforced long-term safety as critical gate

METHODS:
  • Updated Phase 1 protocol reference
