Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages Any age
- All sexes
- No healthy volunteers
- Child, Adult, Older adult
Study population: Analyses will be carried out on all patients included, i.e. who have received at least one unit of octaplasLG®. This population will be stratified based on the different product indications. For the population defined as that of patients with TTP, only those patients for whom the investigator has indicated a confirmed diagnosis of idiopathic TTP will be included in the efficacy analysis (see secondary objective).
Who may be able to join
- The patient is treated with octaplasLG® (receiving at least 1 unit of 200 ml octaplasLG®)
- In accordance with Reference Methodology MR-003, the patient of legal age must be individually informed through an information sheet, and must not oppose participating in this non-interventional study (with no collection of consent). If the patient is unable to receive the information and express any opposition, family members or the trusted person receive the information and must not oppose the collection of data*. For minor patients, one of the holders of parental authority receive the information and must not oppose the collection of data.
- However, the patient in question will be informed if his/her condition later allows.
Who cannot join
- 1) Patient's refusal to participate

About this study
Official title: Observational, Real-life Study of the Use of octaplasLG®.
This observational study enrolls patients who have received at least one infusion of octaplasLG®. OctaplasLG® will be administered standard of care and observation occurs during the treatment and 24 hours after the end of treatment. Characteristics of the use of octaplasLG®, tolerance criteria, and efficacy criteria will be collected.
Read the detailed description
Prospective, non-interventional, multicentre study meeting a post-marketing need. The data will be collected in all patients who have received at least one infusion of octaplasLG®.
The duration of follow-up is limited to the duration of treatment with octaplasLG® plus 24 h of monitoring after cessation of treatment.
Characteristics of the use of octaplasLG® (indication for the transfusion, degree of urgency, characteristics of plasma infusions, patient characteristics, number of iso-group and/or compatible units administered, tolerance criteria (adverse effects), and efficacy criteria (for patients with confirmed diagnosis of TTP--time to normalization of platelet count) will be collected.

The record says: finished, as of the sponsor's last update on 19 Mar 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 14 sites in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Indication for the transfusion of octaplasLG® (time frame: From start of treatment to 24 hours following treatment with octaplasLG®). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Mar 2021; AzTrials last refreshed its copy on 7 Nov 2026.
