Description of intervention(s) / exposure
This study is a single-centre, double-blind, randomized, 2-arm, placebo-controlled, off-label assessment of Rapamycin (Sirolimus), used for the treatment of muscle ageing in combination with exercise.

This study is a post-marketing phase 2a trial. It aims to investigate the effects of a 13-week regimen combining weekly 6mg doses of rapamycin or placebo with a thrice-weekly exercise program (exercycle +30-second chair stand).

Over a 13 week period:
Rapamycine - once weekly 6mg dose. Oral tablet
Placebo - once weekly dose. Oral tablet
Treatments will be provided in blister packs. Used blister packs will be returned to the trial site for reconciliation. Treatment will also be monitored using the patient diary..
At-home exercise regime: 3x per week - 30-second chair stand + exercycle program (starting (week 1) at low resistance for 10 min, building to (week 13) high resistance for 25 min (each workout also includes 2 min warm up and 2 min cooldown) - exercise regime is completed in the participants home. All participants are provided with the same exercycles to standardise the regime. Participants will complete a diary to record exercise adherence and alterations. Site staff will perform weekly contact calls to check participant adherence.

Week Warm-up Training Cooldown
1 2 min @ 50RPM 10 min @70-80RPM, resistance level 1 2 min @ 45RPM
2 2 min @ 50RPM 15 min @70-80RPM, resistance level 1 2 min @ 45RPM
3 2 min @ 50RPM 20 min @70-80RPM, resistance level 2 2 min @ 45RPM
4 2 min @ 50RPM 25 min @70-80RPM, resistance level 2 2 min @ 45RPM
5 2 min @ 50RPM 25 min @70-80RPM, resistance level 3 2 min @ 45RPM
6 2 min @ 50RPM 25 min @70-80RPM, resistance level 3 2 min @ 45RPM
7 2 min @ 50RPM 25 min @70-80RPM, resistance level 4 2 min @ 45RPM
8 2 min @ 50RPM 25 min @70-80RPM, resistance level 4 2 min @ 45RPM
9 2 min @ 50RPM 25 min @70-80RPM, resistance level 5 2 min @ 45RPM
10 2 min @ 50RPM 25 min @70-80RPM, resistance level 5 2 min @ 45RPM
11 2 min @ 50RPM 25 min @70-80RPM, resistance level 5 2 min @ 45RPM
12 2 min @ 50RPM 25 min @70-80RPM, resistance level 5 2 min @ 45RPM
13 2 min @ 50RPM 25 min @70-80RPM, resistance level 5 2 min @ 45RPM

All participants are given the same exercise regime but are able to adjust the regime to complete exercises to the best of their abilities, and document changes in the patient diary.
