The logical way to do it is to have doses starting really tiny, then doubling every ~week.
Every week, patients are given a health survey, and if any effect is obvious in the results data (ie. patients given drug 43 have, on average, a 2 C increased core body temperature), then the dosage of that specific drug is either held fixed (since it is clear we have reached the 'has an effect' dosage), or removed entirely from the trial (if whatever the effect is is deemed likely to hide more valuable yet smaller data from other drugs)

You need 3-6 months on an AD, psychiatic, metabolic, or autoimmune drug to see a Real effect so that is how long you must wait to ramp the dose. It could take years to go from a conservative guaranteed nontoxic dose to an effective one. But in that time most patientss will have gotten tired of waiting and switched drugs, moved to a new city and dropped out of the trial, or die. Sure it could work for some things like antimicrobials or erectile dysfunction drugs that have a rapid response, but that isn't where most of the drug development is. It is in those categories I listed.
