- Brief Summary
Placebo controlled study for safety and efficacy of IMM01-STEM on muscle performance in seniors with obesity and muscle weakness
- Detailed Description
This will be a two-phase, placebo-controlled, dose expansion study that begins with 4 parallel dosing groups and one placebo control group (phase IIa). The treatment period and follow up will last 16 weeks, then an interim adaptation will initiate the second phase of the study (IIb). The study will target safety parameters, body composition, and muscle strength and function. Additional metabolic, inflammatory, and muscle-adipose crosstalk markers will be monitored.
During screening, a wearable activity tracker will be assigned to each participant to establish a baseline of daily physical activity.
The treatment will be administered by intramuscular (IM) in a regimen of two injections per week with 2-3 days intervals between injections, for 4 weeks. The dosing groups vary by IMM01-STEM total protein and will be adjusted for identical volumes or equivalent saline volume for placebo. The proposed doses will be 0.5 mg administered twice per week; 1 mg once per week (alternating with a placebo given on the second visit of the week); 1 mg twice per week; and 2 mg once per week (also alternating with placebo).
Each participant will be evaluated at baseline, at the time of treatment administration during the treatment period, then monthly until the end of trial.
Interim analysis with the purpose of design adaptation will be performed after 10 participants from each group have completed treatment. This point will be marked by the date when the final participant to enroll has completed the final treatment on Week 12. This would occur about 16 weeks after the final participant starts treatment.
Statistical analysis will be performed on all recorded outcomes. All participants will continue to be followed-up per protocol for additional 8 weeks.
Post-adaptation, enrollment will be restarted in accordance with the new randomization rules in a 2-arm placebo-controlled study (IIb). The best responding dose will be chosen, or the most convenient treatment (lowest dose, less frequent administration) in the case that all treatment arms responded equally at interim analysis. An amended clinical protocol will be submitted prior initiation of the phase IIb study.
Study participants will sign a written Informed Consent Form (ICF) prior to any study-related procedures. Treatment must begin within 28 days of signing the ICF, during which participant screening and any necessary drug wash-out period must be completed. Screening assessments will be conducted as specified in the Schedule of Activities of the protocol, after which the study participants' eligibility will be determined based on the inclusion and exclusion criteria.
Site staff will administer study medication by IM injection in the gluteal area using a small-gauge needle at all scheduled treatment visits. If gluteal area is not feasible, alternatively i.m. injection can be administered in the quadriceps or deltoid area. After each administration of study medication, participants will be observed for 1 hour to monitor for acute injection-related reactions and other early onset treatment-related AEs.

- Primary Outcome Measures
Name Time Method Incidence and severity of treatment-emergent adverse events (TEAEs) Time Frame: Day 0 to Day 28 Safety and tolerability of the IP will be measured by regular monitoring of study subjects' vital signs, blood and urine testing, symptom assessments, physical examinations and physical function testing to identify changes that may be related to the IP. Monitoring begins before treatment and continues for three months following the completion of treatment.
Change over time in gait speed Time Frame: Day 0 to Day 171 Muscle strength and function efficacy information from this measure will be used to determine a dosing regimen for a confirmatory expanded study. This will be done using the The European Working Group on Sarcopenia in Older People (EWGSOP2) diagnostic criteria of sarcopenia gait speed.
- Secondary Outcome Measures
Name Time Method Change over time in grip strength Time Frame: Day 0 to Day 171 Muscle strength and function efficacy information from this measure will be considered for alternative efficacy outcome post interim adaptation. This will be done using the The European Working Group on Sarcopenia in Older People (EWGSOP2) diagnostic criteria of sarcopenia hand grip strength.
Change over time in body composition using DXA Time Frame: Day 0 to Day 171 This outcome may be considered for alternative efficacy outcome post interim adaptation.
Change over time in actigraphy parameters as reported by a wearable activity tracker Time Frame: Day 0 to Day 171 This purpose of this measurement is to evaluate additional outcomes that may be considered for alternative efficacy outcome post interim adaptation.
