• Around half of clinical trial outcomes remain unreported, contributing to $170 billion in medical research funding that goes to waste every year
• Existing laws and regulations are typically limited in scope, and compliance is insufficiently monitored and enforced
• Compared to the high cost of conducting clinical trials, the cost of making trial outcomes publicly available is minimal
• Promoting clinical trial transparency is a highly cost-effective way to support the achievement of Social Development Goal 3, access to effective and affordable medicines, and wider global health objectives
