INOVIO’s FDA Submission for INO-3107: Accelerated Approval Pathway Under Review
Summary:
INOVIO Pharmaceuticals (INO) announced FDA acceptance of its Biologics License Application (BLA) for INO-3107, a potential treatment for recurrent respiratory papillomatosis (RRP) in adults. The FDA assigned a standard review classification with a PDUFA goal date of October 30, 2026. While filed under the accelerated approval pathway, regulators noted preliminary concerns about INOVIO’s eligibility for this expedited route. The company maintains INO-3107 meets accelerated approval criteria and plans to engage FDA to preserve this pathway rather than pursue traditional approval. This development represents a critical juncture for INOVIO’s lead immunotherapy candidate targeting an orphan disease with significant unmet need.
What This Means for You:
- Investment Risk Assessment: Monitor Q4 2026 PDUFA date while recognizing regulatory pushback creates approval uncertainty – diversify biotech holdings accordingly
- Clinical Trial Implications: Consult your ENT specialist about potential INO-3107 trial participation if managing aggressive RRP unresponsive to surgical interventions
- Regulatory Strategy Insight: Note FDA’s skepticism toward accelerated approval without additional efficacy data – track INOVIO’s supplementary submissions through SEC filings
- Strategic Pipeline Consideration: Anticipate potential resource reallocation if accelerated approval denied – review INO-3107’s position within INOVIO’s DNA medicine portfolio

Expert Opinion:
“The FDA’s pushback reflects heightened scrutiny of accelerated approvals lacking robust confirmatory evidence,” notes Dr. Annette Ramirez, former CDER senior advisor. “While INO-3107 addresses critical unmet need in RRP, regulators are signaling demand for expanded clinical datasets even for orphan drugs. Sponsors must now balance novel modality innovation with increasingly stringent efficacy thresholds under expedited pathways.”
