ORTHOUNION is a multi-centre, open, comparative, randomized, clinical trial with three parallel arms that aims to compare the efficacy of three treatments to enhance bone healing in patients with long bone non-union.
Bone injuries represent an important world medical problem producing significant healthcare and societal expenditure. While most bone injuries are not severe and are capable of healing through bone regeneration by natural callus formation with standard treatments, severe bone injuries may not heal, becoming an important unmet clinical need.
Non-unions, or pseudarthrosis, may occur in 5% to 20% of long-bone fractures that fail to heal properly after more than 6 months, with morbidity, prolonged hospitalization, and increased expenses. The most commonly accepted standard augmentation to procure fracture and non-union healing consists of autologous bone grafting, obtained from the same patient in a different surgical site and transplanted to the reconstruction site. However, autologous bone grafting has some drawbacks (such as persistent pain, scar, late recovery, limited amount of bone, etc) and a limited regeneration efficacy (success rate of about 74%) and high societal cost. Culture-expanded autologous MSCs combined with biphasic calcium phosphate (BCP) biomaterial granules have been claimed as a solid regenerative medicine alternative to autologous bone grafting in non-unions, although current data are limited. In this context, the ORTHOUNION initiative focuses on the opportunity to test the hypothesis of superiority of MSC, the investigational ATMP, versus the currently accepted standard therapy, iliac crest bone autograft to biologically augment surgical treatment of long-bone non-unions.

Exclusion Criteria:
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.
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.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
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.
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 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.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
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.

Bone consolidation
The percentage of bone consolidation in the comparator treatment arm ( iliac crest autograft) and experimental treatment arm (mesenchymal cells).
Time frame: 12 months after treatment
Bone consolidation
To compare bone consolidation between the experimental arms and the comparator
Time frame: 6 and 24 months
Radiological Bone consolidation
To compare bone consolidation, using the REBORNE scale, between the experimental arms and the comparator. The REBORNE scale is an ad-hoc and validated scale, developed by Gomez-Barrena et al. (article currently under preparation) as a modification of the RUST score (Whelan, 2010; Journal of Trauma). In the REBORNE scale, the presence/absence of radiological consolidation is evaluated on a total of 4 cortices. Score range from 0 (no bone callus visible) to 4 (callus present with same density as cortical). The total score will be recorded.
Time frame: 6, 12 and 24 months
Level of Pain
To compare level of pain (by Numeric Rating Scale \[NRS\]) between the experimental arms and the comparator. The NRS is a scale that rates the patient´s pain from 0-10 (0= no pain, 10= worst pain), at the time of the visit.
Time frame: 6, 12 and 24 months
Complications
To compare the rate of complications between the experimental arms and the comparator
Time frame: 6, 12 and 24 months
Health status
To compare the health status (by using the Short Form-36 Health Questionnaire) between treatment arms. The SF-36 questionnaire is a validated, widely used patient-reported health survey which measures their physical and mental health status. It consists of 36 questions organized in 8 dimensions. The total score will be recorded.
Time frame: 6, 12 and 24 months
Ran from Sep 2017 to primary completion in Oct 2022, 61 months.
