NCT ID: NCT05066958 Recruiting - Clinical trials for Acute Myeloid Leukemia

Ex-vivo Primed Memory Donor Lymphocyte Infusion to Boost Anti-viral Immunity After T-cell Depleted HSCT

Start date: September 16, 2021
Phase: Phase 1/Phase 2
Study type: Interventional

HSCT from an allogeneic donor is the standard therapy for high-risk hematopoietic malignancies and a wide range of severe non-malignant diseases of the blood and immune system. The possibility of performing HSCT was significantly limited by the availability of donors compatible with the MHC system. However, modern ex-vivo and in vivo technologies for depletion of T lymphocytes have made it possible to improve the outcomes of HSCT from partially compatible related (haploidentical) donors. In representative groups, it was shown that the success of HSCT from haploidentical donors is not inferior to standard procedures of HSCT from HLA-compatible unrelated donors. HSCT from haploidentical donors in children associated with the deficit of the adaptive immune response, which persists up to 6 months after HSCT and can be an increased risk of death of the patient from opportunistic infections. To solve this problem, the method of infusion of low doses of donor memory T lymphocytes was introduced. This technology is based on the possibility of adoptive transfer of memory immune response to key viral pathogens from donor to recipient. Such infusions have been shown to be safe and to accelerate the recovery of the pathogen-specific immune response. The expansion of virus-specific T lymphocytes in the recipient's body depends on exposure to the relevant antigen in vivo. Thus, in the absence of contact with the viral antigen, the adoptive transfer of memory T lymphocytes is not accompanied in vivo by the expansion of virus-specific lymphocytes and does not form a circulating pool of memory T lymphocytes, that can protect the patient from infections. Therefore the investigators assume that ex-vivo priming of donor memory lymphocytes with relevant antigens can provide optimal antigenic stimulation and may solve the problem of restoring immunological reactivity in the early stages after HSCT. Technically ex-vivo primed memory T lymphocytes will be generated by short incubation of CD45RA-depleted fraction of the graft (a product of T lymphocyte depletion) with a pool of GMP-quality peptides representing a number of key proteins of the viral pathogens. The following are proposed as targeted antigens: CMV pp65, EBV EBNA-1, EBV LMP12A, Adeno AdV5 Hexon, BKV LT, BKV VP1. An infusion of donor memory lymphocytes will be performed on the day +1 after transplantation. Parameters of the assessment will be safety and efficacy (immune response by day 60 and stability (responses by day 180).

NCT ID: NCT04975919 Active, not recruiting - Clinical trials for Refractory Acute Myeloid Leukemia

Venetoclax in Combination With Decitabine and Cedazuridine for the Treatment of Relapsed or Refractory Acute Myeloid Leukemia

Start date: September 29, 2021
Phase: Phase 2
Study type: Interventional

This phase II trial studies the effects of venetoxlax in combination with decitabine and cedazuridine in treating patients with acute myeloid leukemia that has come back (relapsed) or does not respond to treatment (refractory). Chemotherapy drugs, such as venetoclax and decitabine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Cedazuridine may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving venetoxlax in combination with decitabine and cedazuridine may help to control acute myeloid leukemia.

NCT ID: NCT04942730 Recruiting - Clinical trials for Myelodysplastic Syndromes

Benadamustine, Fludarabine and Busulfan Conditioning in Recipients of Haploidentical Stem Cell Transplantation (FluBuBe)

FluBuBe
Start date: January 21, 2021
Phase: Phase 2
Study type: Interventional

Haploidentical hematopoietic stem cell transplantation irrespective of the conditioning and graft-versus-host disease prophylaxis is associated with high frequency of primary and secondary graft failure. Different technologies of with replete or depleted graft are associated with 10-20% of graft failures. Fludarabine and busulfan conditioning is the most commonly used approach for a variety of disease. Furthermore combination of fludarabine and bendamustine was sufficient to facilitate engraftment in patients with chronic lymphocytic leukemia and lymphomas. The aim of the study is to evaluate whether addition of bendamustine to fladarabine and busulfan conditioning reduces the risk of primary graft failure after haploidentical allograft.
