Correct data analysis help

Im designing an experimental plan, and I am looking at whether cognitive remediation combined with A cognitive enhancer is more effective than cognitive remediation alone in reducing cognitive deficits for bipolar patients (fmri). I’m not sure what data analysis to use. Between subjects I would like to have 4 treatment groups so (treatment - treatment + cognitive enhancing drug, treatment & placebo, treatment as usual, and healthy controls measured pre treatment only for baseline comparison), and for within subject factor there will be 3 time points. Can I do a repeated measures ANOVA or will this not work with that many treatment groups?
