Injection of ex Vivo Amplified G-CSF Mobilised Autologous Peripheral Blood Stem Cell Transplantation (Expansion)

August 4, 2026 updated by: University Hospital, Bordeaux

Pilot Clinical Trial of Injection of ex Vivo Amplified G-CSF Mobilised Autologous Peripheral Blood Stem Cell Transplantation in Adult Patients With Multiple Myeloma in First Response

Hematopoietic reconstitution defined by a neutrophils number > 500/mm3 at day 7 after injection of ex vivo amplified graft and by a platelets number > 20000/mm3, at day 15 after the injection of ex vivo amplified graft, without transfusion.

Study Overview

Detailed Description

To check that injection of autologous peripheral blood stem cell CD34(+) "amplified ex vivo in the presence of SCF, G-CSF and TPO in HP01 Maco pharma medium culture. ": Allows to obtain a hematopoietic reconstitution:

  1. Rapid : 7 days or less after the injection, regarding neutrophils and 15 days or less regarding platelets
  2. Complete: numbers neutrophils and platelets respectively higher than 500/mm3 and 20000/mm3 within the times mentioned
  3. Stable: no secondary neutropenia or thrombocytopenia during the year following the injection, in the absence of recurence of the myeloma.
