Brief summary
The objectives of this study are to evaluate the utility of two gastrointestinal (GI) symptom scales (Individual GI Symptom and Impact Scale {IGISIS} and Global GI Symptom and Impact Scale {GGISIS}) in assessing GI tolerability in adult subjects with RRMS after administration of ALKS 8700 or Dimethyl Fumarate (DMF) in Part A, to compare the GI tolerability of ALKS 8700 and DMF in adult subjects with RRMS using IGISIS and GGISIS in Part B, and to Evaluate the safety and tolerability of ALKS 8700 in adult subjects with RRMS in Parts A and B.
