The Hidden Gap Between Phase III Success and Market Access: When Evidence Misalignment Delays Commercial Readiness
For many biopharma teams, Phase III is treated as the final mountain to climb. Once efficacy and safety are proven, commercial readiness is assumed to follow naturally. In reality, that assumption is one of the most costly missteps in drug development. More assets than ever are reaching regulatory approval on time, yet facing slower-than-expected uptake, prolonged access negotiations, or restrictive reimbursement decisions. The issue isn’t clinical failure. It’s evidence of misalignment.
