Overview
There is a great amount of information available from scholars in medical research and research in general who are able to point out the benefits and limitations of random controlled trials (RCT) in research. RCT can be of value in many cases, but in others they are inappropriate. They are not by any stretch of the imagination “the gold standard.” They are just another mechanism for producing evidence, and can help to reduce some sorts of confounds. It is epistemologically naive to suggest that they somehow trump other investigative methods.
Claiming that Random Controlled Trials (RCT) are the only method to gain scientific understanding shows a limited knowledge of the history of science. Scientific evidence, the production, evaluation and interpretation, is much more complicated than that.
There are big issues pertaining to research designs, controls, confounds, randomization, statistics, bias, incentive and deception which anyone using scientific evidence to make a judgment or buttress an argument should understand. The discussions become very technical. All scientific evidence is underdetermined. One study does not establish a case; it only points in a certain direction.
Limitations of RCT are discussed briefly in the article here and here.
Below is a reading list obtained via Google Internet searching. I have not looked at more than a fraction of these, and have looked carefully at only a very few.

Norman Doidge, a contributing writer for Tablet, is a psychiatrist, psychoanalyst, and author of The Brain That Changes Itself and The Brain’s Way of Healing. “The phrase, “all else being equal,” is crucial, because so often all else is not equal. Simply repeating “RCTs are the gold standard of evidence-based medicine” implies to the naive listener that if it is an RCT then it must be a good study, and reliable, and replicable. It leaves out that most studies have many steps in them, and even if they have a randomization component, they can be badly designed in a step or two, and then lead to misinformation. Then there is the very uncomfortable fact that, so often, RCTs can’t even be replicated, and so often contradict each other, as anyone who has followed RCTs done on their own medical condition often sadly finds out. …. “ |

Randomized Controlled Trials (RCTs) are the “gold standard” for evaluating treatment outcomes providing information on treatments “efficacy”. They are designed to test a therapeutic hypothesis under optimal setting in the absence of confounding factors. For this reason they have high internal validity. The strict and controlled conditions in which they are conducted, leads to low generalizability because they are performed in conditions very different from real life usual care. |

Video
Ian Tannock, MD, PhD, DSc, from the University of Toronto, Toronto, Canada, discusses the disadvantages of randomised trials at the European Cancer Congress of the European Cancer Organisation (ECCO) 2017 in Amsterdam, Netherlands. Randomised trials are considered the gold standard for testing novel treatments, however, there are some disadvantages. Firstly, participants are carefully selected, and will rarely have a comorbid disease. The drugs tend to therefore be more efficacious in clinical trials than they do in practice. Clinical trials are now commonly funded by pharmaceutical companies. This means that progression free survival is often used as an endpoint, as it is the minimum at which the FDA and the EMA will approve registration. An improvement in progression free survival, however, is not always indicative of an improvement in overall survival. Therapies shown to be statistically significant are usually approved by the FDA and the EMA, and new therapies can be expensive. Their cost, however, has no correlation to their efficacy. ESMO and ASCO have introduced value scales, balancing toxicity with the benefits, in the hope of determining clinically important treatment, not just statistically significant.” |
