Why Are Clinical Trials Complicated?

During a dinner conversation last week, I was reflecting on why clinical trials are so complicated.

It all boils down to three reasons.

Human Motivation

Many of us (including myself) underestimate human psychology and motivation.

At an individual level, we are each motivated by different things, such as status, money, freedom, etc.

At a macro level:

  • Private for-profit organizations want to maximize profits (think CROs, biopharmaceutical and medical device companies).
  • Non-profit organizations want to achieve their mission (think large academic sites).
  • The government (think US Food and Drug Administration) wants patients to be safe.

When there is a mismatch between individual and institutional motivation, project planning and execution become difficult.

There is a delicate dance going on between individuals and institutional motivations. When we conduct clinical trials, we can’t ignore human motivation.

Human Health

When we’re sick, the only thing that matters is improving our health and feeling better.

Clinical trials can provide human subjects with hope for better health.

But hope doesn’t always turn into reality. A patient’s health may improve, may stay the same, or in some cases worsen.

We just don’t know.

In routine clinical care, doctors perform their duties under medical guidelines using commercially available medical products.

There is clear evidence on what works and what doesn’t.

When we’re conducting clinical trials, we don’t know the impact of our work on human health.

This uncertainty can be painful and frustrating.

Healthcare Laws

Healthcare laws, specifically clinical trial laws and regulations, reside at the intersection of medical innovation and human safety.

In other words, the government has enacted laws to protect clinical trial participants from unwanted side effects of medical innovation, such as a new drug or medical device.

The hardest parts of conducting clinical trials within any legal framework are as follows:

  1. Laws keep changing with advances in technology (for example, medical products built with artificial intelligence and machine learning algorithms require a new set of regulations).
  2. Every country, state, and city have their own legal structure which can be difficult to navigate, (for example, in the State of California, patients not only review and sign the research informed consent, but are also required to review and sign the Experimental Bill of Rights when participating in a clinical trial).
  3. The medical standard of care can vary within and across geographies. In other words, treatment protocols may differ between countries or even between hospital systems.

Conclusion

In summary, human motivation, human health, and healthcare laws make clinical trials a complicated endeavor to pursue and manage.

If you can master one or more of these three forces at play, you can have a positive impact on clinical trial design and conduct.
