Study Arms:
- Clenbuterol (Type: EXPERIMENTAL): Initially, 40 mcg each morning for one week. Then, increase to 40 mcg BID for the next 5 weeks. If tolerated, will increase to 80 mcg in the morning and 40 mcg in the evening for one week. Then, last dose increase will be 80 mcg BID until week 52.
- Placebo Comparator (Type: PLACEBO_COMPARATOR): Initially, one capsule each morning for one week. Then, increase to one capsule BID for the next 5 weeks. If tolerated, will increase to two capsules in the morning and one capsule in the evening for one week. Then, last dose increase will be two capsules BID until week 52.

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