Acute Myeloid Leukemia clinical trials at UCSF

The purpose of this study is to determine the recommended Phase 2 dose(s) (RP2D[s]) of bleximenib in phase 1 (Part 1 [Dose Escalation] and to determine the safety and tolerability at RP2D in Phase 1 Part 2 (Dose expansion). The purpose of the Phase 2 part of the study is to evaluate the efficacy of bleximenib at the RP2D.

This is a prospective, multi-center, Phase II study of hematopoietic cell transplantation (HCT) using human leukocyte antigen (HLA)-mismatched unrelated donors (MMUD) for peripheral blood stem cell transplant in adults and bone marrow stem cell transplant in children. Post-transplant cyclophosphamide (PTCy), tacrolimus and mycophenolate mofetil (MMF) will be used for for graft versus host disease (GVHD) prophylaxis. This trial will study how well this treatment works in patients with hematologic malignancies.

This phase III trial compares hematopoietic (stem) cell transplantation (HCT) using mismatched related donors (haploidentical [haplo]) versus matched unrelated donors (MUD) in treating children, adolescents, and young adults with acute leukemia or myelodysplastic syndrome (MDS). HCT is considered standard of care treatment for patients with high-risk acute leukemia and MDS. In HCT, patients are given very high doses of chemotherapy and/or radiation therapy, which is intended to kill cancer cells that may be resistant to more standard doses of chemotherapy; unfortunately, this also destroys the normal cells in the bone marrow, including stem cells. After the treatment, patients must have a healthy supply of stem cells reintroduced or transplanted. The transplanted cells then reestablish the blood cell production process in the bone marrow. The healthy stem cells may come from the blood or bone marrow of a related or unrelated donor. If patients do not have a matched related donor, doctors do not know what the next best donor choice is. This trial may help researchers understand whether a haplo related donor or a MUD HCT for children with acute leukemia or MDS is better or if there is no difference at all.

Quizartinib is an experimental drug. It is not approved for regular use. It can only be used in medical research. Children or young adults with a certain kind of blood cancer (FLT3-ITD AML) might be able to join this study if it has come back after remission or is not responding to treatment.

Tagraxofusp is a protein-drug conjugate consisting of a diphtheria toxin redirected to target CD123 has been approved for treatment in pediatric and adult patients with blastic plasmacytoid dendritic cell neoplasm (BPDCN). This trial aims to examine the safety of this novel agent in pediatric patients with relapsed/refractory hematologic malignancies. The mechanism by which tagraxofusp kills cells is distinct from that of conventional chemotherapy. Tagraxofusp directly targets CD123 that is present on tumor cells, but is expressed at lower or levels or absent on normal hematopoietic stem cells. Tagraxofusp also utilizes a payload that is not cell cycle dependent, making it effective against both highly proliferative tumor cells and also quiescent tumor cells. The rationale for clinical development of tagraxofusp for pediatric patients with hematologic malignancies is based on the ubiquitous and high expression of CD123 on many of these diseases, as well as the highly potent preclinical activity and robust clinical responsiveness in adults observed to date. This trial includes two parts: a monotherapy phase and a combination chemotherapy phase. This design will provide further monotherapy safety data and confirm the FDA approved pediatric dose, as well as provide safety data when combined with chemotherapy. The goal of this study is to improve survival rates in children and young adults with relapsed hematological malignancies, determine the recommended phase 2 dose (RP2D) of tagraxofusp given alone and in combination with chemotherapy, as well as to describe the toxicities, pharmacokinetics, and pharmacodynamic properties of tagraxofusp in pediatric patients. About 54 children and young adults will participate in this study. Patients with Down syndrome will be included in part 1 of the study.

This study aims to use clinical and biological characteristics of acute leukemias to screen for patient eligibility for available pediatric leukemia sub-trials. Testing bone marrow and blood from patients with leukemia that has come back after treatment or is difficult to treat may provide information about the patient's leukemia that is important when deciding how to best treat it, and may help doctors find better ways to diagnose and treat leukemia in children, adolescents, and young adults.

This trial is evaluating the safety and tolerability of venetoclax with chemotherapy in pediatric and young adult patients with hematologic malignancies, including myelodysplastic syndrome (MDS), acute myeloid leukemia derived from myelodysplastic syndrome (MDS/AML), and acute lymphoblastic leukemia (ALL)/lymphoblastic lymphoma (LBL). The names of the study drugs involved in this study are below. Please note this is a list for the study as a whole, participants will receive drugs according to disease cohort. - Venetoclax - Azacitidine - Cytarabine - Methotrexate - Hydrocortisone - Leucovorin - Dexamethasone - Vincristine - Doxorubicin - Dexrazoxane - Calaspargase pegol - Hydrocortisone

This study is an access and distribution protocol for unlicensed cryopreserved cord blood units (CBUs) in pediatric and adult patients with hematologic malignancies and other indications.
