Would it be possible to ask doctor to prescribe chloroquine/amodiaquine for off-label use? harvard recently found them extremely effective for pd.

You can always ask: A healthy patient-physician relationship should make you comfortable making reasonable request. Having said that, if I know which study you are referring to - one has to keep in mind the study is very much a laboratory study showing chloroquine/amodiaquine can activate Nurr1, a "master switch" for brain regeneration, in petri dish. Clinical efficacy has NOT being proven.
