The document discusses public-private partnerships (PPPs) for drug development, specifically for orphan and neglected diseases. It outlines the traditional private drug development process, challenges of developing drugs for diseases that do not have large patient populations able to pay, and how PPPs aim to address this by bringing together public and private sector expertise and resources. One example of a PPP, Bayer's Grants4Targets program, provides early-stage research funding for academic scientists while allowing them to retain intellectual property rights. The document raises debates around ensuring PPPs are effective and that resulting drugs are accessible to those in need.
