TGD001-behandling ved trombotisk mikroangiopati
En adaptiv dosiseskalerings- og ekspansionskurvundersøgelse til at udforske sikkerheden, farmakologien og den kliniske aktivitet af TGD001 ved immunmedieret trombocytopenisk trombocytopenisk purpura (iTTP) og andre trombotiske mikroangiopatier
This is a Phase 1/2, prospective, adaptive design trial of TGD001 in participants with suspicion or clinical diagnosis of acute immune thrombotic thrombocytopenic purpura (iTTP) episodes and participants with suspicion or clinical diagnosis of an acute Thrombotic Microangiopathy (TMA) episode. The trial is an open-label, dose escalation and expansion basket trial.

Detaljeret beskrivelse
In Part A, dose escalation of TGD001 is conducted in participants with suspicion or clinical diagnosis of immune thrombotic thrombocytopenic purpura (iTTP) in conjunction with their respective standard of care to identify a tolerated dose(s) with a pharmacological/clinical response to be evaluated in Part B.
Once a recommended dose of TGD001 is established in Part A, the dose expansion/basket part of the trial will commence. In Part B, "basket" cohorts of participants with iTTP and other Thrombotic Microangiopathies (TMAs) will receive single or repeat doses of TGD001 in conjunction with their respective standard of care to determine the TGD001 dose and treatment regimen with clinical effect in reducing the initial thrombus burden.
Baskets will include up to 20 participants each and may be combined based on emerging safety and efficacy findings. Baskets may be further expanded with the TGD001 dose(s) and regimen(s) that displayed the best clinical response as assessed by the Data Safety Management Committee up to a total of approximately 60 participants in Part B.

Plan for individuelle deltagerdata (IPD)
Planlægger du at dele individuelle deltagerdata (IPD)?
IPD-planbeskrivelse
IPD will not be shared due to the small sample size in this early phase clinical trial in a rare patient population. Such a small sample size would pose a significant risk of re-identification of study participants.
