You were obviously on to something and it's frustrating yet completely expected to see all replies with pat dismissals that anything like this gets when there is some real potential innovation in healthcare.

Google 'chronotherapy' with some chemo/cancer/immunotherapy related terms and you'll find a ton of research being done. Given that most of it seems to have evolved in the last 8 years my guess is that the concept was 'vetted' by a nobel prize in 2017 for molecular circadian clock, so people feel safe putting their name on studies in this area.
