FDA Approves Hundreds of Drugs Without Adequate Evidence of Effectiveness, Investigation Reveals
- A two-year investigation found that 73% of the 429 drugs approved by the FDA from 2013-2022 failed to meet the agency's four foundational standards for proving effectiveness.
- Cancer drugs showed particularly concerning approval patterns, with only 2.4% of 123 cancer treatments meeting all four scientific criteria and 81% approved based on preliminary surrogate outcomes rather than survival data.
- The investigation documented cases like Elmiron, which remained on market for nearly three decades despite causing blindness and having no proven efficacy, highlighting systemic failures in post-market confirmation studies.
