Publicly funded clinical trials and the future of cancer care

Publicly sponsored trials, conducted primarily by cooperative groups sponsored by the National Cancer Institute, and commercially sponsored trials are necessary to create new knowledge, improve the care of oncology patients, and develop new drugs and devices. Commercial sponsors launch clinical trials that will result in drug approval, label extension, expansion of market share, and an increase in shareholder value. Conversely, publicly sponsored trials seek to optimize therapy for a particular disease, create new knowledge, and improve public health; these trials can also result in label extension of a drug and even in initial drug approval. Publicly sponsored trials may combine and/or compare drugs developed by different commercial sponsors, develop multimodality therapies (e.g., the combination of chemotherapy and radiation), or develop novel treatment schedules or routes of drug administration (e.g., intraperitoneal chemotherapy). Publicly sponsored trials are more likely to focus on therapies for rare diseases and to study survivorship and quality of life; these areas may not be a priority for commercial entities. Screening and prevention strategies have been developed almost exclusively by the public sector given the large sample size and long follow-up period needed to complete the trial and, therefore, the lack of short-term commercial gain. Finally, given the public nature of the funding, clinical investigators are expected to publish their results even if the outcomes are unfavorable for the investigational therapy. With the ongoing reorganization of the cooperative groups to form a national clinical trials network, opportunities exist to create a robust platform for biomarker discovery and validation through the expanded collection of well-annotated biospecimens obtained from clinical trial participants. Thus, publicly funded trials are vital to developing and refining new cancer treatments and disseminating results to the medical community and the general public.
