Sit Less, Interact and Move More (SLIMM) 2 Study

Study Overview
=================
Brief Summary
-----------------
Prolonged sitting (sedentary behavior) is a risk factor for decreased kidney function, obesity, diabetes and mortality. Prolonged sitting is associated with decreased kidney function and increased risk of diabetes, heart disease and death. In a previous pilot study funded by NIH, it was shown that a Sit Less, Interact and Move More (SLIMM) intervention targeting sedentary behavior in people with kidney disease was able to decrease prolonged sitting but that effect was not sustained. Therefore, the researchers are currently conducting a follow-up study named Sit Less, Interact and Move More (SLIMM) 2. This NIH funded study is conducted at the University of Utah and Stanford University. The purpose of this study is to see if guided resistance training (to improve muscle strength) and semaglutide (FDA approved diabetes and weight loss medication that might also improve physical function) can boost adherence to the SLIMM Intervention and reduce sedentary behavior.

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Placebo Comparator: SLIMM + Standard RT + Placebo<br>SLIMM intervention for 3 months, followed by a 9-month intervention of SLIMM, standard-of-care resistance training and oral placebo | Behavioral: SLIMM<br>* Increase in light walking activity, replacing 1 hour/day of sedentary duration with casual walking duration. Increase in sedentary breaks, from sitting/lying position to standing position, at least once every hour as independent of the total time spent on sedentary activities.<br>Behavioral: Standard Resistance Training<br>* Participants will be provided a standard resistance training regimen to follow during the course of the study. Participants will not receive individualized instruction, guidance or modification to the resistance training regimen.<br>Drug: Placebo<br>* Oral placebo tablets (matching the experimental semaglutide) will be administered from the first through ninth months of the drug intervention period.<br>|
| Active Comparator: SLIMM + Guided RT + Placebo<br>SLIMM intervention for 3 months, followed by a 9-month intervention of SLIMM, guided resistance training and oral placebo | Behavioral: SLIMM<br>* Increase in light walking activity, replacing 1 hour/day of sedentary duration with casual walking duration. Increase in sedentary breaks, from sitting/lying position to standing position, at least once every hour as independent of the total time spent on sedentary activities.<br>Behavioral: Guided Resistance Training<br>* Supervised resistance training sessions are individualized for a low-resistance, high-repetition regimen of lower body major muscle groups with established guidelines. Instructions and resistance training bands will be provided for home use. Study participants will record compliance to the resistance training regimen for further guidance and potential modification.<br>Drug: Placebo<br>* Oral placebo tablets (matching the experimental semaglutide) will be administered from the first through ninth months of the drug intervention period.<br>|
| Experimental: SLIMM + Guided RT + Semaglutide<br>SLIMM intervention for 3 months, followed by a 9-month intervention of SLIMM, guided resistance training and oral semaglutide | Behavioral: SLIMM<br>* Increase in light walking activity, replacing 1 hour/day of sedentary duration with casual walking duration. Increase in sedentary breaks, from sitting/lying position to standing position, at least once every hour as independent of the total time spent on sedentary activities.<br>Behavioral: Guided Resistance Training<br>* Supervised resistance training sessions are individualized for a low-resistance, high-repetition regimen of lower body major muscle groups with established guidelines. Instructions and resistance training bands will be provided for home use. Study participants will record compliance to the resistance training regimen for further guidance and potential modification.<br>Drug: Semaglutide<br>* Oral semaglutide 3 mg/day will be administered for the first month of study drug intervention period, if tolerated, the dose will increase to 7 mg/day for the second month and to a maximum dose of 14 mg/day from the third through ninth months of the drug intervention period.<br>|
