February 2022 - The post-natal group is closed to new participants

17th June 2021 - Prenatal Group in the BOOSTB4 trial is open for inclusion at Karolinska University Hospital

17th March, 2020 - Clinical trial has started.

The BOOSTB4 project consortium announces initiation of the clinical trial phase of the project with the enrolment of the first patient to the trial on March 17, 2020. The patient received the first of four fetal Mesenchymal Stem Cell (fMSC) infusions at the Karolinska University Hospital in Stockholm, Sweden and was discharged as planned at the conclusion of a monitoring period of 48 hours. Three more infusions will follow with a 3-5 month separation between infusions.

The principal objective of the European Commission’s Horizon 2020 funded BOOSTB4 project (Grant Agreement number 681045) is to conduct a Phase I/II clinical trial of the safety and efficacy of pre- and/or postnatal fMSC transplantation in the severest forms of OI (type III, severe type IV). The trial’s primary outcome is safety; secondary outcomes relate to efficacy (fracture frequency, growth, bone mineral density and quality of life). Although the trial will involve recruitment of pre-natal as well as post-natal patients, the first 5 patients to be recruited will be to the post-natal arm of the trial to allow a safety evaluation to be undertaken before the pre-natal arm of the trial is opened.
