Brief Summary:
The objectives of this study are to assess the efficacy, safety, and tolerability of PLX-PAD intramuscular administration for the treatment of muscle injury following arthroplasty for HF.

Condition or disease Intervention/treatment Phase
Hip Fracture Drug: PLX-PAD Drug: Placebo Phase 3

Detailed Description:

This will be a Phase III, multinational, randomized, double-blind, placebo-controlled study, assessing the efficacy, safety, and tolerability of intramuscular (IM) administration of allogeneic PLX-PAD cells for the treatment of muscle injury following arthroplasty for HF as compared to placebo treatment. Both treatment arms will receive standard of care treatment per local practice.

The study will comprise 2 periods:

  1. Main study period - from Screening to 52 weeks post-treatment. During this period, the subjects will have the following study visits: Screening, Day 0 (treatment and surgery day), Day 1, Day 5, Week 6, Week 12, Week 26 and Week 52.
  2. Safety follow-up period - from Week 52 to Week 104. During this safety follow-up period, there will be a phone call visit at Week 104, and only related serious adverse events (SAEs) and new malignancy adverse events will be collected.

The main study period will comprise 4 periods:

  1. Screening and pre-surgery time
  2. Surgery and treatment with PLX-PAD or placebo (Day 0)
  3. Hospital follow-up until Day 5±1, at least
  4. Follow-up period up to 52 weeks following study treatment administration. Subjects will be assessed for study eligibility before the emergency surgery for HF. After being found eligible, subjects will be randomized using a 1:1 allocation scheme to either 150×106 PLX-PAD cells or to placebo treatment, respectively. Within 48 hours of admission and up to 72 hours following fracture, subjects will undergo HA or THA. During the surgical procedure, the subjects will receive the investigational product in accordance with the treatment group to which they were randomized. Thereafter, visits will be conducted at Days 1 and 5±1, and at Weeks 6, 12, 26, 52 and 104.

Drug Information available for: PlasmaLyte

Arm Intervention/treatment
Experimental: PLX-PAD
• Arm 1 - PLX-PAD (120 subjects): 150×10^6 PLX-PAD cells (10×10^6 cells/mL) in a mixture containing 10% DMSO (v/v), 5% HSA (w/v) and PlasmaLyte.
PLX-PAD (120 subjects): 150×106 PLX-PAD cells (10×106 cells/mL) in a mixture containing 10% DMSO (v/v), 5% HSA (w/v) and PlasmaLyte

Placebo Comparator: Placebo
Arm 2 Placebo (120 subjects): Placebo (solution comprised of 10% DMSO [v/v], 5% HSA [w/v], and PlasmaLyte, without cells).
Drug: Placebo
Arm 2 Placebo (120 subjects): Placebo (solution comprised of 10% DMSO [v/v], 5% HSA [w/v], and PlasmaLyte, without cells).

Primary Outcome Measures :
  1. Short Physical Performance Battery (SPPB) score [ Time Frame: Week 26. ]

Secondary Outcome Measures :
  1. Hip abduction strength of the injured leg [ Time Frame: Week 26. ]
  2. Change from baseline to Week 52 in lower extremity measure (LEM) (retrospective collection of pre-fracture LEM at Day 5±1). [ Time Frame: baseline to Week 52 ]
  3. Lean Body Mass of the injured leg at Week 26 (dual-energy x-ray absorptiometry [DEXA]). [ Time Frame: Week 26 ]
  4. SPPB score [ Time Frame: Week 52. ]
    The Short Physical Performance Battery (SPPB) is an objective assessment tool for evaluating lower extremities function. The SPPB consists of 3 types of physical maneuvers: balance test, speed gait test, and chair stand test. Results from each maneuvers test are scored on a scale of 0 to 4, with an increasing composite score indicating an improved lower extremities function level. The total maximum score of SPPB is 12.
