Mesenchymal Stromal Cells to Treat Type 1 Diabetes in Children and Adolescents
A Double-blinded, Randomized, Parallel, Placebo-controlled Trial of Wharton's Jelly-derived Allogeneic Mesenchymal Stromal Cells to Treat Type 1 Diabetes in Children and Adolescents
Source: ClinicalTrials.gov · Last updated 28 Apr 2026
Brief summary (registry, in English)
This is a combined phase 1 and 2 study in 66 subjects, male or female, between 7-21 years of age that have recently (\< 6 months) been diagnosed with type 1 diabetes. The first phase 1 part of the study includes six subjects openly receiving allogeneic Wharton's jelly derived mesenchymal stromal cells as the Advanced Therapy Medicinal Product (ATMP) Protrans, three each in the age ranges 7-11 and 12-18.The second part is a randomized, double-blinded placebo-controlled phase 2 study in parallel design comparing allogeneic Wharton's jelly derived mesenchymal stromal cells treatment (as Protrans) to placebo in children and adolescent subjects (7-21 years of age) diagnosed with type 1 diabetes, The primary objectives of this study will be to investigate the safety, tolerance and efficacy after an allogieneic infusion of Wharton's jelly derived mesenchymal stromal cells.

Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Prior treatment
- Subjects with latent or previous as well as on-going therapy against tuberculosis, or exposed to tuberculosis or has traveled in areas with a high risk of tuberculosis or mycosis within the last 3 months.
- Subjects with serological evidence of infection with HIV, Treponema pallidum, hepatitis B antigen (subjects with serology consistent with previous vaccination and a history of vaccination are acceptable), or hepatitis C.
- Subjects with known, or previous, malignancy.
- Subject with any condition or any circumstance that, in the opinion of the investigator, would make it unsafe to undergo treatment with MSC.
Other illness
- Subjects with unstable cardiovascular status incl. NYHA class III/IV or symptoms of angina pectoris.
- Subjects with uncontrolled hypertension (≥160/105 mmHg).
- Subjects with active on-going infections.
- Subjects with a known demyelinating disease or with symptoms or physical examination findings consistent with possible demyelinating disease.
- Known hypersensitivity against any excipients, i.e., dimethyl sulfoxide (DMSO).
Lab values
- Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive hCG laboratory test.
- Taking oral anti-diabetic therapies or any other concomitant medication which may interfere with glucose regulation other than insulin.
- Subjects with GFR \<60 ml/min/1.73 m2 body surface.
Other
- Subjects with body weight \>100 kg
- Subjects with any systemic immune suppressive treatment
Who the study is looking for
- Written informed consent for participation of the study (for subjects below 18 years of age also from both caregivers), given before undergoing any study-specific procedures
- Clinical history compatible with type 1 diabetes diagnosed less than 6 months before enrolment
- In the first part of the study, six subjects, three between 7-11 and three between 12-18 years of age (both groups inclusive at both ends), will be included. The sixty subjects in the second part of the study are stratified by age (12-21 and 7-11 years, respectively) and randomized to one of two treatment arms (active or placebo), with a 6-month safety delay for the younger stratum.
- Mentally stable and, in the opinion of the investigator, able to comply with the procedures of the study protocol.
- Fasting plasma C-peptide concentration \>0.12 nmol/L.
- Subjects of child-bearing potential must agree to using adequate contraception until one year after the administration of WJMSC/Placebo. Adequate contraception is as follows:
- oral (except low-dose gestagen (lynestrenol and noretisteron), injectable or implanted hormonal contraceptives.
- intrauterine device
- intrauterine system (for example progestin-releasing coil)
- vasectomized male (with appropriate postvasectomy documentation of the absence of sperm in the ejaculate)
