That's right in many cases, but not all.
In some trials there is no placebo. The new treatment is measured
against the existing standard of care, e.g., a trial of Abiraterone vs.
Lupon. I wish more trials were done that way.
Also, in some trials that do have placebos, they may provide an option
whereby, if the disease is progressing on the placebo, the patient may
be able to move to the experimental drug. So if a clinical trial looks
interesting, it's necessary to read the details and, if it still looks
interesting, contact a trial site and ask questions.
Even where there is a straight drug vs. placebo, the ratio is not always
1:1. 2:1 is not uncommon nowadays with two people getting the
experimental treatment for each one on placebo.
Clinical trials are chancy. Most new treatments don't work out. But
they are the only path by which treatments advance. Unfortunately, one
of the barriers to progress in treating cancer and other diseases is
that not enough people sign up for clinical trials. Many trials are
abandoned because they can't recruit enough patients. So people who do
join a trial should know that they are doing an important service for
everyone as well as getting a possible shot at a valuable new treatment.
