Study Description

Brief Summary:

An open-label dose escalation study to assess the safety and tolerability of IMMUNA(IMM01-STEM) in participants with muscle atrophy related to knee osteoarthritis

Condition or disease	Intervention/treatment	Phase
Muscle Atrophy	Drug: IMM01-STEM	Phase 1; Phase 2

Detailed Description:

This will be an open-label, dose escalation study to assess the safety and tolerability of IMMUNA(IMM01-STEM), a secretome product derived from partially differentiated pluripotent stem cells that contains regenerative molecules, in participants with muscle atrophy related to knee osteoarthritis (KOA).

Up to 18 participants will receive twice weekly intramuscular administration of IMMUNA(IMM01-STEM) for 4 weeks in up to 3 dose cohorts: Cohort A, IMMUNA 225μg; Cohort B, IMMUNA 450 μg; and Cohort C, IMMUNA 900 μg.

Study participants will sign a written Informed Consent Form (ICF) prior to the conduct of any study related procedures. A study participant who provides written informed consent will be screened within 28 days prior to treatment. Screening assessments will be conducted, after which the study participants' eligibility will be determined on the basis of the inclusion and exclusion criteria.

Eligible participants will be enrolled and undergo Baseline assessments on Day 1. Patients will receive IMM01-STEM twice a week for 4 weeks, for a total of 8 injections. Site staff will administer study medication by im injection using a small-gauge needle (eg, 24 or 26 Ga) at all scheduled visits. After each administration of study medication, participants will be observed for 3 hours to monitor for injection-related reactions and other early onset treatment-related adverse events (AEs), in particular for the presence of allergic reactions. After Visit 2 and 3, there will be follow-up phone contact 6 to 8 hours later the same day and once the day following each injection.

After their last injection, participants will enter a Safety Follow-Up (SFU) period, with clinic visits 3 days after their last injection and then monthly for 3 months.

Outcome Measures

Primary Outcome Measures :

1. Safety of IMMUNA(IMM01-STEM) treatment in study participants with muscle atrophy related to KOA [ Time Frame: Day 0 to Day 28 ]
   Determined by the incidence and severity of dose-limiting toxicities (DLTs) and the incidence of treatment-emergent adverse events (TEAEs). Adverse events (AE) are classified based on Common Terminology Criteria for Adverse Events (CTCAE) as follows: Grade 0 = no adverse events, Grade 1= mild, Grade 2 = moderate, Grade 3 = severe, Grade 4 = life threatening and Grade 5 = fatal adverse events. A DLT is defined as any AE related to IMM01-STEM of a Grade 2 unresolved within 48 hours post-injection, or any Grade 3, 4, or 5 related to IMM01-STEM during any time of treatment or during the 48-hour, acute/subacute observation period.

Secondary Outcome Measures :

1. Safety and tolerability of IMMUNA(IMM01-STEM) after 4 weeks of treatment in study participants with muscle atrophy related to KOA [ Time Frame: Day 28 ]
   Determined by incidence, type and severity of adverse events graded according to CTCAE v5.0 and CRS revised grading system and defined by clinical relevant findings at day 28 post-treatment, or worsening of previous findings from baseline at day 28 post treatment in: self-reporting, physical examination, vital signs (body temperature, body weight, blood pressure, and heart rate), laboratory data (hematology, clinical chemistry, and urinalysis).
2. Functionality of the knee joint after 4 weeks of treatment with IMMUNA(IMM01-STEM) in study participants with muscle atrophy related to KOA [ Time Frame: Day 28 ]
   Determined by evaluation of participants with changes from baseline at day 28 post treatment in: muscle strength (measured by isometric knee extensor torque), physical function (measured by the 6-minute walk test), Western Ontario and McMaster Universities Osteoarthritis (WOMAC) Index
