About this trial
The goal of this research study is to find the safest and most effective dose of the study drug, BXCL701, for the treatment of Acute Myeloid Leukemia (AML) or Myelodysplastic Syndrome (MDS).
The names of the study drugs involved in this study are/is:
* BXCL701
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Age 18 and older
Relapsed AML: as evidence by ≥5% myeloblasts in the bone marrow, or reappearance of blasts in the peripheral blood
Refractory AML: ≤2 prior induction regimens (example: patients who receive 7 + 3 followed by 5 + 2 would count as one induction regimen) OR
Subjects with WHO defined myelodysplastic syndrome with excess blasts-2 (MDS-EB-2) as defined by blast count between 10% - 19% in the bone marrow or peripheral blood blasts 5% - 19% or Auer rods noted and who are refractory or relapsed after at least 4 cycles of a hypomethylating agent (azacitidine, decitabine, or oral decitabine/cedazuridine)
Disqualifiers
Subjects who have known Acute Promyelocytic Leukemia.
Subjects with active CNS involvement with AML.
Participants who have had chemotherapy, other investigational therapy, immunotherapy, or radiotherapy within 2 weeks or 5 half-lives from prior therapy, whichever is longer, prior to the first dose of study medication. Hydroxyurea is allowed with no required washout, and hydroxyurea may be administered for the first cycle of the protocol for patients who have proliferative disease (WBC <25K) with a maximum allowed dose of 6 g per day.
Participants who have received oral tyrosine kinase inhibitors (TKIs) within two weeks or 5 half-lives (whichever is longer) of the first dose of study medication

Trial outcomes
Primary outcomes
Maximum Tolerated Dose (MTD)
Defined as the highest dose at which fewer than one-third of patients experience a dose-level toxicity (DLT). MTD will be used to inform recommended Phase II dose. If no DLTs are observed, the MTD is not reached.
Number of Participants with treatment related Adverse Events per CTCAE 5.0
Assessed using NCI Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.
Secondary outcomes
Complete Remission (CR) Rate
Proportion of patients who have the response, criteria are based upon International Working Group (IWG) and European LeukemiaNet (ELN) criteria for Acute Myeloid Leukemia (APPENDIX D) and Myelodysplastic Syndrome (APPENDIX F).
Complete Response with Incomplete Count Recovery (CRi) Rate
Proportion of patient who has the response, criteria are based upon International Working Group (IWG) and European LeukemiaNet (ELN) criteria for Acute Myeloid Leukemia (APPENDIX D) and Myelodysplastic Syndrome (APPENDIX F).
Partial Response (PR) Rate
Based upon International Working Group (IWG) and European LeukemiaNet (ELN) criteria for AML (APPENDIX D) and MDS (APPENDIX F). Defined as decrease by \>= 50% in blast percentage to 5-25% or to \<= 5% with auer rods present in marrow; normalization neutrophil count \>= 1000μL and platelet count \>= 100000μL.
Morphologic Leukemia-free State (MLFS) Rate
Evaluated only in AML patients per the 2017 ELN criteria (Dohner, Blood 2017, PMID: 27895058), defined as: Bone marrow blasts \<5%; absence of blasts with Auer rods; absence of extramedullary disease; no hematologic recovery required.
