Study Arms:
- Fentanyl (Type: EXPERIMENTAL): Fentanyl subcutaneously (SQ) dose equivalent to 15-25% of the morphine equivalent daily dose (MEDD) 15 minutes before walk test, and 6 minute walk test (6MWT) at baseline and 15 minutes after Fentanyl. Two (2) Questionnaires completed at baseline taking about 10 minutes to complete, and one completed after study visit taking about 5 minutes to complete.
- Placebo (Type: ACTIVE_COMPARATOR): Normal saline 0.9% preservative free SQ 15 minutes before walk test, and 6 minute walk test at baseline and 15 minutes after Placebo. Two (2) Questionnaires completed at baseline taking about 10 minutes to complete, and one completed after study visit taking about 5 minutes to complete.

Based on this trial design, predict the completion outcome and termination type (if applicable).
