Q1 2024 Earnings Summary
- Strong Clinical Differentiation: pz‐cel has demonstrated robust efficacy in challenging, chronic wounds—with over 67% of cases showing greater than 75% healing and significant pain reduction—underscoring its potential to provide substantial clinical benefits for RDEB patients [Index 5][Index 7].
- Clear Regulatory Path: The company is addressing the FDA's CMC concerns through completed validation studies and proactive informal engagements, supporting a disciplined plan for a BLA resubmission in the second half of 2024, which aligns with achieving key regulatory milestones [Index 2][Index 8].
- Early Commercial Engagement: Positive interactions and one-on-one discussions with commercial payers have bolstered confidence in the product’s value proposition, paving the way for favorable market access and reimbursement post-approval [Index 4].
- Regulatory delays risk: The resubmission timeline for the BLA has been softened to the second half of 2024 due to the need to validate all remaining CMC deficiencies, which introduces uncertainty regarding the speed of regulatory approval.
- Clinical endpoint challenges: The Q&A highlighted that complete wound healing was not achieved in chronic wounds in the pivotal study, raising concerns about the therapy’s effectiveness in fully resolving the most challenging cases.
- Assay alignment concerns: There is uncertainty regarding the cell-based identity assay, as the approach—though seemingly straightforward—relies on ongoing informal meetings with the FDA to ensure its sensitivity and specificity, which could present hurdles if alignment is delayed.

BLA Timeline
Q: Clarification on resubmission timeline?
A: Management clarified that the resubmission is still planned for Q3, with language broadened to “second half 2024” to allow extra time for final FDA alignment. This means no material change in approach, just a buffer for external uncertainties. -
Cell-Based Assay
Q: FDA alignment on identity assay?
A: They are confident in their cell-based identity assay, having received positive feedback from the FDA on the proposed sensitivity and specificity, ensuring robust product characterization ahead of resubmission. -
SCC Label
Q: Can treatment claim prevent SCC?
A: While early data are encouraging, management noted it is premature to include a preventive claim for SCC on the label without additional clinical data, so this remains under evaluation. -
Endpoints Analysis
Q: How significant are wound healing endpoints?
A: Management emphasized that achieving 50% or 75% wound healing is highly meaningful for patients, especially given the chronic and large wounds treated, with pain reduction further corroborating the therapy’s benefits. -
Market Sizing
Q: Has market size evolved with genetic testing?
A: They observed increased genetic testing and better biopsy data uncovering misclassified cases, suggesting a potentially larger accurately diagnosed market despite historical misclassification, reinforcing the long-term value proposition.
