A Trial to Assess Haploidentical T-depleted Stem Cell Transplantation in Patients With SCD
A Phase II Stratified Trial to Assess Haploidentical T-depleted Stem Cell Transplantation in Patients With Sickle Cell Disease With no Available Sibling Donor
Study Overview
Status
Conditions
Detailed Description
Can an α/ß depleted T-Haplo-HSCT with regard to disease free survival, adverse events and safety be considered equivalent to a matched sibling donor transplantation (MSD), in order to offer cure for the majority of patients with sickle cell disease.
The main questions of this trial are:
- Safety of a α/ß T-depleted haploidentical HSCT
- Incidence of acute and chronic GvHD
- Rate of rejection
- Immune reconstitution
- Fertility It is expected that the use of TCRαβ+ and CD19+ depleted haploidentical cell grafts in combination with the less aggressive and well tolerated conditioning regimen needed for patient preparation will be associated with a low risk of grade II-IV aGVHD and no extensive cGvHD, no graft failure and increase speed, spectrum and functionality of immune system reconstitution. This is supposed to reduce the incidence of severe infections leading to lower rates of transplantation related mortality (TRM).

Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Overall survival
Time Frame: up to 2 years after transplantation

Overall survival rate (OS) is defined as time from transplantation to death or last follow-up and will be assessed at Day 100 and after 1 year and 2 years.
|
up to 2 years after transplantation
|
Disease free survival
Time Frame: up to 2 years after transplantation

Quality of life: EQ-5D
Time Frame: up to 2 years after transplantation
|
Adult patients ≥18 years. The European Quality of Life 5 Dimension (EQ-5D) questionnaire has two components: health state description and evaluation. In the description part, health status is measured in terms of five dimensions (5D); mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Mobility dimension asks about the person's walking ability. Self-care dimension asks about the ability to wash or dress by oneself, and usual activities dimension measures performance in "work, study, housework, family or leisure activities". In pain/discomfort dimension, it asks how much pain or discomfort they have, and in anxiety/depression dimension, it asks how anxious or depressed they are. |
up to 2 years after transplantation

Quality of life: PedsQL
Time Frame: up to 2 years after transplantation
|
The Pediatric Quality of Life Inventory (PedsQL) is a 23-item generic health status instrument with parent and child forms that assesses five domains of health (physical functioning, emotional functioning, psychosocial functioning, social functioning, and school functioning) in children and adolescents ages 2 to 18.

up to 2 years after transplantation
|
Quality of life: FACT-BMT
Time Frame: up to 2 years after transplantation
|
Functional Assessment of Cancer Therapy-Bone Marrow Transplant (adult patients ≥18 years).
FACT-BMT form was designed to measure the QoL in patients undergoing bone marrow transplantation.
It combines the FACT-G, an assessment of physical well-being, social/family well-being, emotional well-being and functional well-being, with Bone Marrow Transplantation Sub-scale(BMTS) to measure the QOL of BMT patients.
