Medical Researchers Have Incentive to Exclude Older Patients from Clinical Trials

As human beings, medical researchers would like to offer experimental therapies to whoever needs them and is willing to take the risks and uncertainty of new frontiers. But as practical medical researchers medical researchers know their careers depend on the success of their clinical trials, and the success of their clinical trials depends on the number of patients who thrive on the new therapy. So their personal incentive is to cherry-pick clinical trial enrollees, picking only the most robust who are most likely to thrive. The solution? Allow medical researchers to be both human beings and medical researchers. Allow them to give the therapy to those at high risk, based on their cumulative experience and judgement. Not all sound actionable knowledge arises from randomized double-blind clinical trials.

(p. A5) Many cancer trials cap enrollment at age 65. Even when trials for older people are available, oncologists are reluctant to enroll elderly patients because frailties might make them less resilient against side effects from toxic treatments, according to a 2020 study in an American Cancer Society journal. People over 70 represent a growing share of the cancer-patient population but are vastly underrepresented in clinical trials, the study said.

“How can we make decisions for people over 70 if people over 70 are not included in the trials that we use to base our decision making?” said Dr. Mina Sedrak, deputy director of the Center for Cancer and Aging at City of Hope, a cancer center near Los Angeles and an author of the paper.

The Food and Drug Administration guidelines recommend “adequate representation” of the elderly in cancer trials, including people over age 75. The Journal of the National Cancer Institute in December 2022 published a series of papers presented at a workshop focused on how to improve trial enrollment of older people.

Researchers have developed geriatric assessment tools that try to predict patients’ survival chances based on more than age alone. Professional groups are also working to try to address gaps. Despite these efforts, enrollment of older patients still lags behind, cancer doctors said.

To participate in many trials involving transplants, patients would have to undergo the more intense chemotherapy whether randomly assigned to receive an experimental treatment or the standard of care. That makes it harder to incorporate older patients into randomized trials, cancer doctors said.
