Optimization: Improved Drug Discovery Problem The average cost to develop a new pharmaceutical is nearly $2.2 billion. A large portion of this cost is due to the inefficiency of pre-clinical research: it takes 10,000 small molecules initially screened to yield just 10 candidates for clinical trials, and fewer than 10% of 1 clinical trial candidates result in a new drug. Solution Large-scale quantum computers will offer many potential improvements to this process, including more accurate computational chemistry and effect modeling. Reducing the cost of development by just 10% would translate to a customer benefit of $200 million.
