Study 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.

Read the 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 survival and quality of life data, 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.

Terms in these criteria, in plain language(13)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

HbA1c

A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

What researchers measure

Primary outcomes

  1. Short Physical Performance Battery (SPPB) score

    Time frame: Week 26.

Secondary outcomes

  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. SPPB score

    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.

    Time frame: Week 52.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 28, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
