A Study Evaluating the Safety and Pharmacokinetics of ABBV-744 in Subjects With Advanced Prostate Cancer (CRPC) and Relapsed/Refractory Acute Myeloid Leukemia (AML) Cancer

This is an open-label, Phase 1, dose-escalation (Segment 1) and expansion (Segment 2) study to determine the maximum tolerated dose (MTD) and the recommended phase two dose (RPTD), and to assess the safety, preliminary efficacy, and pharmacokinetic (PK) profile of ABBV-744 for participants with metastatic Castrate Resistant Prostate Cancer (CRPC) and relapsed/refractory Acute Myeloid Leukemia (AML).

Participants with AML who are candidates for stem cell transplantation must have been offered this therapeutic option. Must meet additional criteria specific for each diagnosis, metastatic CRPC and relapsing/remitting AML, as described in the protocol.
  • Must consent to provide biomarker analyses as described in the protocol.
  • Must have an Eastern Cooperative Oncology Group (ECOG) Performance status of:
  • Dose Escalation (Segment 1): 0 - 1
  • Dose Expansion (Segment 2): 0 - 2
  • Dose Escalation: Must have a serum albumin during Screening of >= 3.2 g/dL.
  • Participant has adequate bone marrow, renal and hepatic function.

Exclusion Criteria:

  • Participant has untreated brain or meningeal metastases.
  • Participant has received anti-cancer traditional medicine or anti-cancer herbal remedies within 14 days prior to ABBV-744 dosing. Saw palmetto is considered anti-cancer herbal remedy.

Participant with AML has received anti-cancer therapy within a period of 14 days or 5 half-lives (whichever is longer; except for immunotherapy where a period of 21 days will be acceptable) prior to Study Day 1. Except for hydroxyurea which will be allowed during screening and treatment for controlling leukocytosis for AML subjects.
  • Participant has been previously treated with a Bromodomain and Extra-Terminal (BET) inhibitor

  • Participant consumed grapefruit or grapefruit products within 3 days prior to the first dose of study drug.
  • Participant had major surgery within 28 days prior to Study Day 1.
  • Participant is unable to swallow or absorb oral tablets.
