Insights

Biotech regulatory and risk analyst

FDA not approvable letter is a significant setback for VenoValve.

The company reports that the U.S. Food & Drug Administration issued a not approvable letter for the Premarket Approval application of VenoValve, its surgical replacement venous valve for severe deep chronic venous insufficiency. In FDA practice, this means the current application cannot be approved as submitted and typically requires substantial additional data, analyses, or changes.

Because VenoValve is a key product candidate aimed at a serious vascular condition, this regulatory outcome is likely important for the company’s development plans and timeline. The disclosure also emphasizes that forward-looking statements, including those about clinical trials, are subject to risks and uncertainties referenced in the company’s Annual and Quarterly Reports, underscoring that future progress will depend on how it addresses the FDA’s concerns.
