Should l Buy INO?
Source: Fool
- Development Progress: Inovio Pharmaceuticals' candidate drug INO-3107 targets approximately 14,000 cases of recurrent respiratory papillomatosis (RRP) annually, and if approved, it could achieve peak sales of up to $1.1 billion, indicating significant commercial potential.
- Regulatory Hurdles: Although Inovio requested FDA accelerated approval for INO-3107, the FDA rejected this strategy due to insufficient justification, which may delay the drug's market entry and increase the risks faced by the company.
- Manufacturing Complexity: INO-3107 requires administration via Inovio's proprietary Cellectra electric device, which not only raises production costs but may also lower acceptance among physicians and insurers, complicating commercial rollout.
- Historical Setbacks: Inovio has faced multiple regulatory setbacks in recent years, including the failure of the phase 3 clinical trial for VGX-3100, highlighting significant challenges in R&D and market promotion, which could lead to continued stock price declines in the medium term.
