Before It's Too Late: Multistakeholder Perspectives on Compassionate Access to Investigational Drugs for Pediatric Patients With Cancer.

Patients and their families, physicians, drug companies, and regulatory agencies have common goals: to find effective therapies for life-threatening conditions. In oncology, the lines between clinical research and treatment are often blurred; parents and physicians of patients who have exhausted standard-of-care treatments and cannot participate in a clinical trial are likely to consider seeking compassionate use access to investigational drugs; however, knowledge and perspectives about compassionate use may differ among these groups. There are unique considerations associated with providing compassionate use to children diagnosed with cancer, including evaluation for potential developmental toxicities, the need for pediatric-specific dosing and formulations, informed consent, and, when appropriate, patient assent. Positive impacts of providing access to investigational therapies to children include potential treatment benefits to patients who obtain investigational agents as well as benefits to future patients if data from expanded access support drug development for childhood cancer. Challenges for physicians seeking compassionate use access to investigational drugs for their patients include obtaining the drug sponsor's agreement to provide the investigational drug as well as lack of knowledge about the process and regulatory requirements. Clinical trials in oncology provide the possibility of therapeutic benefit for pediatric patients; when feasible and warranted, these benefits should also be available to patients on a compassionate use basis outside of trials.
