New hope for kids with tough leukemia: experimental drug enters human testing
NCT ID NCT07306832
First seen Jun 27, 2026 · Last updated Sep 10, 2026 · Updated 12 times
Summary
This early-stage study is testing an experimental drug called pivekimab sunirine in about 18 children whose acute myeloid leukemia (AML) has come back or not responded to standard treatments. The main goals are to check the drug's safety and how it moves through the body. Participants will receive the drug by IV, and researchers will monitor side effects and any signs that the leukemia is responding.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Must have histologically confirmed acute myeloid leukemia (AML) meeting one of the following disease criteria: * Second or greater relapse. OR * Disease refractory to second or subsequent line of therapy (defined as resistant disease after at least one cycle of each treatment regimen). * Must have myeloid leukemic blasts that are CD123-positive by flow cytometry as determined by the treating institution. * Has \>= 5% myeloid leukemic blasts in bone marrow at time of relapse or refractory disease and prior to Screening for this study. * Performance status by Lansky (\< 16 years old at evaluation) or Karnofsky (\>= 16 years old at evaluation) score \>= 50 or ECOG score \<= 2. * May have status of central nervous system (CNS)1, CNS2, or CNS3 disease without clinical signs or neurologic symptoms suggestive of CNS leukemia, such as facial nerve palsy, brain/eye involvement or hypothalamic syndrome. Participants receiving intrathecal therapy and no additional CNS-directed systemic therapy at study entry are eligible and may continue treatment as clinically indicated in accordance with institutional practice. * For those participants who have not reached the age of consent, parent or legal guardian with the willingness and ability to provide informed consent and participant willing and able to give assent, as appropriate for age and country.
