About this study

Official title: Randomized Adaptive Study for Safety and Efficacy of Pluripotent Cell Secretome on Muscle Performance in Seniors With Sarcopenic Obesity

Placebo controlled study for safety and efficacy of IMM01-STEM on muscle performance in seniors with obesity and muscle weakness

Read the 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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • IMM01-STEMBiological

    IMM01-STEM is an allogeneic cell-free secretome product derived from partially differentiated human stem cells derived from a pluripotent embryonic stem cell line that was established from a single donor IVF discarded blastocyst. The cells are cultivated in bioreactors and the product of their secretion is collected, purified and concentrated to a standardized formulation. The secretome contains a mixture of molecules related to immunomodulation, growth, and extracellular matrix remodeling. This intervention is given 2mL twice a week.

  • PlaceboOther

    Also called Saline

    Saline. This intervention is given 2mL twice a week.

  • IMM01-STEM alternating with placebo (saline)Biological

    This intervention consists of IMM01-STEM given once a week and placebo given one a week. IMM01-STEM is an allogeneic cell-free secretome product derived from partially differentiated human stem cells derived from a pluripotent embryonic stem cell line that was established from a single donor IVF discarded blastocyst. The cells are cultivated in bioreactors and the product of their secretion is collected, purified and concentrated to a standardized formulation. The secretome contains a mixture of molecules related to immunomodulation, growth, and extracellular matrix remodeling.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence and severity of treatment-emergent adverse events (TEAEs)

    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.

    Measured: Time Frame: Day 0 to Day 28

  2. Change over time in gait speed

    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.

    Measured: Time Frame: Day 0 to Day 171

Secondary outcomes (3)
  1. Change over time in grip strength

    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.

    Measured: Time Frame: Day 0 to Day 171

  2. Change over time in body composition using DXA

    This outcome may be considered for alternative efficacy outcome post interim adaptation.

    Measured: Time Frame: Day 0 to Day 171

  3. Change over time in actigraphy parameters as reported by a wearable activity tracker

    This purpose of this measurement is to evaluate additional outcomes that may be considered for alternative efficacy outcome post interim adaptation.

    Measured: Time Frame: Day 0 to Day 171
