This study is evaluating how safe a new drug (called ABBV-787) is, and how it moves within the body, in adults with relapsed or refractory acute myeloid leukaemiaA Phase 1 First-in-Human Study Evaluating Safety, Pharmacokinetics and Efficacy of ABBV-787 in Adult Subjects With Acute Myeloid Leukemia (AML)

Clinical summary


ABBV-787 is an investigational drug being developed for the treatment of acute myeloid leukaemia (AML). Eligible participants will receive ABBV-787 in escalating doses until the maximum tolerated dose (MTD) is determined. Approximately 60 adult participants with a diagnosis of AML will be enrolled worldwide.

Participants will receive intravenous (IV) infusions of ABBV-787 during the approximately 3 year duration a participant is followed.

  • Documented diagnosis of non-promyelocytic acute myeloid leukemia (AML), per 2022 European Leukemia Net (ELN) criteria.
  • Participants with relapsed/refractory (R/R) acute myeloid leukemia (AML) who have been treated with up to 3 prior lines of therapy and are refractory to or intolerant of all established AML therapies that are known to clearly provide clinical benefit at the judgement of the investigator.
  • Must have a white blood cell (WBC) count < 25 × 10^9 /L prior to initiation of study drug (Note: Hydroxyurea or leukapheresis is permitted to meet this criterion and for use through Cycle 3 to control for hyperleukocytosis.).


  • Have received a CD33-targeting therapy within 3 months prior to the first dose of ABBV-787.
  • Stem cell transplant within 3 months prior to first dose of study drug.
  • Have received anticancer therapy including chemotherapy, radiation therapy, immunotherapy, biologic, or any investigational therapy within 14 days or 5 half-lives of the drug (whichever is shorter) prior to the first dose of ABBV-787.
  • History of documented pneumonitis that required treatment with systemic steroids within the last 6 months, nor any evidence of active pneumonitis.
  • Unresolved toxicity of Grade >= 2 from prior anticancer therapy, or to levels dictated in the eligibility criteria, with the exception of alopecia.
  • Known active severe or poorly controlled acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.


  • You have had a certain type of treatment or surgical procedure.
  • You have had treatment but your cancer has gotten worse or has not responded to the treatment you have been given.
  • You have had treatment, but your cancer has come back.


  • You have certain types of non-cancer medical conditions.
  • You have had certain treatments, surgical procedures or drugs.
