Smart Immune to Present Details of Pioneering Clinical Study at the American Society of Hematology (ASH) Annual Meeting 2023
PARIS, France, 02 November 2023 – Smart Immune, a clinical-stage biotechnology company developing ProTcell, a thymus-empowered T cell progenitor therapy platform to fully and rapidly re-arm the immune system against tumors and infection, today announced that a poster featuring SMART101, the first T cell progenitor therapy product in development from the Company’s ProTcell platform, will be presented at the American Society of Hematology (ASH) Annual Meeting to be held 09-12 December 2023 in San Diego, California.
The poster will present details of the ReSET-02 clinical study that is underway seeking to provide proof of concept that a novel type of T cell progenitor cells – the Company’s SMART101 asset – can rapidly complete their differentiation into naïve T cells within a patient’s thymus, accelerating the reconstitution of a fully-competent polyclonal T cell repertoire after allogeneic hematopoietic stem cell transplantation (allo-HSCT). In this protocol, adult leukemia patients will undergo a specific blood stem cell transplant procedure, called ‘Haplo PTCy’, from a haploidentical donor (a family member), followed by the administration of cyclophosphamide that reduces the risks of graft-versus-host disease (GvHD). Six days after the transplantation, the patients will receive an infusion of SMART101, produced in Paris, from the same healthy donor.
An improvement in allo-HSCT clinical outcomes is expected from this first-of-a-kind thymus-empowered approach, leading to better overall survival and lower co-morbidity rates. If the primary endpoints are met as anticipated, the study will also show the biological activity of SMART101 to reverse thymic involution.

Karine Rossignol, Chief Executive Officer of Smart Immune, said: “We are excited to present details from the ReSET-02 clinical study at ASH this year. Demonstrating the safety and efficacy of our lead asset SMART101 in the standard-of-care setting for haploidentical transplant is critical. The Haplo PTCy setting is increasingly used in the EU and the US, as donors are family members and therefore easier to find. However, the delayed T cell reconstitution observed in patients puts them at risk of infections and relapses. By expediting T cell reconstitution post-transplant, we expect to improve the overall clinical outcomes and increase the benefit/risk ratio of haploidentical transplant.
About Smart Immune
Smart Immune is a clinical-stage biotechnology company developing ProTcell, a thymus-empowered T cell progenitor therapy platform to fully and rapidly re-arm the immune system, enabling next-generation allogeneic T cell therapies for all. The company aims to radically improve outcomes for patients with life-threatening diseases such as high-risk blood cancers and primary immunodeficiencies. Smart Immune has ongoing collaborations with leading institutions in the US and Europe. SMART101 is already in Phase I/II clinical trials, in the EU and the US, looking at the acceleration of complete immune recovery in patients fighting cancer and infection and undergoing allogeneic hematopoietic stem cell transplantation. Smart Immune is also developing therapies using gene-modified T cell progenitors through its ProTcell platform to provide targeted treatments against cancer or AIDS, like persistent off-the-shelf CAR T cells or HIV-resistant T cells. The Company is headquartered in Paris, France, at Paris Biotech Santé.
