Expensive Drug Prices for Rare Cancers: Are Patients Truly Benefitting?

Cancer medicines comprise the largest proportion of expensive drugs for rare diseases (EDRDs). The US Orphan Drug Act (ODA) (Office of Inspector General, Department of Health and Human Services 2001) encourages pharmaceutical manufacturers to develop medicines for rare diseases through a range of financial incentives, which has shifted the development of cancer medicines to rare cancer subtypes. Although certain medicines approved through the ODA have revolutionized cancer treatment, only half demonstrate added therapeutic benefit compared to existing alternatives. Canadian regulators should ensure that cancer medicines that receive fast-track approval through the Health Canada Notice of Compliance with conditions offer benefit to Canadian patients. Furthermore, payers might engage in methods for reassessment and renegotiations over the medicines' lifespan.
