Effects of mTOR Inhibition on Muscle Health in Older Adults

Impacts of Mechanistic Target of Rapamycin (mTOR) Inhibition on Aged Human Muscle.

Not applicable Interventional University of Nottingham · NCT05414292

This study is testing if a medication called Rapamune can help older adults with muscle loss get stronger when they do resistance exercises.

What this trial studies

This study investigates the effects of inhibiting the mechanistic target of rapamycin (mTOR) on muscle health in older adults experiencing muscle atrophy and age-related sarcopenia. Participants will undergo unilateral resistance exercise training while receiving Rapamune (sirolimus) to assess its impact on muscle protein synthesis and overall muscle function. The study aims to explore whether mTOR inhibition can enhance muscle responses to exercise in individuals who may not be able to engage in regular physical activity. By understanding the role of mTOR in muscle maintenance, the research seeks to identify potential therapeutic strategies for combating age-related muscle loss.

Who should consider this trial

Good fit: Ideal candidates for this study are older adults who are physically able to participate in resistance exercise training and are experiencing muscle atrophy or sarcopenia.

Not a fit: Patients with significant cardiovascular, respiratory, or metabolic diseases, or those with a BMI outside the specified range, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new pharmacological approach to improve muscle mass and function in older adults, enhancing their quality of life and independence.

How similar studies have performed: While the approach of mTOR inhibition has shown promise in animal studies, this specific application in humans is novel and has not been extensively tested.

Inclusion Criteria:

* Participant is willing and able to give informed consent for participation in the study
* Participant is physically able to complete the resistance exercise training programme

Exclusion Criteria:

* • A BMI \<18 or \>35 kg/m2

  * Active cardiovascular, cerebrovascular or respiratory disease: e.g. uncontrolled hypertension (BP \> 160/100), angina, heart failure (class III/IV), arrhythmia, right to left cardiac shunt, recent cardiac event, COPD, pulmonary hypertension or recent stroke
  * Any metabolic disease

  * Having taken part in a research study in the last 3 months involving invasive procedures or an inconvenience allowance (this must remain for ALL UoN FMHS UREC approved studies)
  * Contraindications to MRI scanning including claustrophobia, pacemaker, metal implants etc. which will be assessed through an MRI safety screening questionnaire.
  * Contraindications to the use of Rapamycin e.g. those due scheduled vaccinations (as rapamycin can reduce the efficacy of vaccines).
