Relapsed/Refractory Acute Myeloid Leukemia (AML)

This is a single-arm, open-label, dose-escalation, prospective exploratory clinical study intended to evaluate the safety, efficacy and cellular pharmacokinetics of GT737 cells in adult patients with relapsed/refractory acute myeloid leukemia (AML).

Every patient responds differently to their cancer treatment, and some treatments work better for some patients more than others. For patients with relapsed, refractory ( R/R) AML, there may be fewer approved treatment options remaining. In this research study, the investigators are testing whether high throughput drug screening (HTS) in combination with robust molecular testing by HopeSeq (includes DNA sequencing for \>500 genes and 160 gene rearrangements and RNAseq for \>5,000 genes) can help doctors determine which treatment might work best for each individual patient. HTS tests how the patient's own AML cells respond to different treatment options including individual drugs and triple drug regimens and recommends for the best treatment options for an individual patient. Participants will provide extra bone marrow and/or blood at the time of routine procedure, and these extra sample(s) will be tested using the Cancer Drug Sensitivity Test ( CDST) HTS, CLIA approved in Washington state since 2014. A committee (the Functional Molecular Tumor Board) will review the HopeSeq and HTS results, past treatments, and clinical description, and give a recommendation for the best AML treatment options for each individual patient. The patient's doctor will get a copy of the recommendation and discuss treatment options with the patient. The patient and their doctor will decide on the best treatment plan for the patient, one which will be approved by insurance. Patients will not be treated with any drugs as part of this study. Then at 6 and 12 months, there will be retrospective review of medical records to determine how will the testing predicted the response, drug sensitivity or resistance, and overall and disease-free survival will be monitored.

CLN-049-001 is a Phase 1, open-label, multicenter, first-in-human trial of CLN-049 in patients with Relapsed/Refractory Acute Myeloid Leukemia (AML) or Myelodysplastic Syndrome (MDS)

Study GB3226-DEV-001 is a Phase 1/2, open-label, dose-escalation and expansion study of GB3226 in the treatment of relapsed or refractory acute myeloid leukaemia

Abstract: This clinical study is designed to evaluate the efficacy and safety of a thiotepa, busulfan, and fludarabine (TBF) conditioning regimen for haploidentical hematopoietic stem cell transplantation (haplo-HSCT) in elderly patients (≥55 years) with high-risk acute myeloid leukemia (AML). A total of 56 eligible patients will be enrolled in this prospective, single-arm, multicenter trial. Study Design: This is a multicenter, single-arm, prospective clinical trial. Eligible patients will receive the following conditioning regimen: thiotepa 5 mg/kg/day on Days -10 to -9; busulfan 3.2 mg/kg/day on Days -8 to -6; fludarabine 30 mg/m²/day on Days -6 to -2; and rabbit anti-thymocyte globulin (rATG) 1.5-2.5 mg/kg/day on Days -5 to -2. Hematopoietic stem cell infusion will be performed on Day 0. Graft-versus-host disease (GVHD) prophylaxis will include cyclosporine A (CsA), mycophenolate mofetil (MMF), and methotrexate (MTX). The primary endpoint of this study is 1-year relapse-free survival (RFS). Inclusion Criteria: Age 55-70 years (inclusive). Diagnosis of high-risk AML , include relapsed/refractory AML or CR MRD+ or ELN22 adverse risk group .Relapsed/refractory AML defined as at least one of the following: recurrence of leukemia cells in peripheral blood or bone marrow blasts \>5% after complete remission (CR), failure to achieve remission after two courses of standard induction therapy, relapse within 12 months after consolidation therapy, relapse after 12 months that is refractory to conventional chemotherapy, multiple relapses, or persistent extramedullary leukemia）. Scheduled to undergo haploidentical hematopoietic stem cell transplantation (haplo-HSCT). Adequate organ function. Eastern Cooperative Oncology Group (ECOG) performance status ≤2. Written informed consent obtained. Exclusion Criteria: Unwillingness or refusal to accept the study treatment protocol. Presence of donor-specific anti-HLA antibodies. Known human immunodeficiency virus (HIV) infection. Active hepatitis B or C, or chronic active hepatitis. Uncontrolled active infection at the time of enrollment. Any other condition deemed by the investigator as unsuitable for study inclusion.

The study "GALAXY33" is an open-label, prospective, nonrandomized, one arm phase I clinical trial in which patients with relapsed AML after allogeneic hematopoietic stem cell transplantation will be transplanted with CD33-deleted CD34+ HSC derived from the initially matched family donor.

NTQ2494 tablet, an anti-tumor molecular targeted drug, is an AXL kinase inhibitor. The objectives were to evaluate the safety and tolerability, PK characteristics and preliminary efficacy of NTQ2494 tablets in patients with advanced hematological malignancies.
