Acute Myeloid Leukemia Clinical Trial

STAT Inhibitor OPB-111077, Decitabine and Venetoclax in Treating Patients With Acute Myeloid Leukemia That Is Refractory, Relapsed or Newly Diagnosed and Ineligible for Intensive Chemotherapy

Summary

This phase I trial studies the side effects and best dose of STAT inhibitor OPB-111077 when given together with decitabine and venetoclax in treating patients with acute myeloid leukemia that does not respond to treatment (refractory), has come back (relapsed), or is newly diagnosed and ineligible for intensive chemotherapy. STAT inhibitor OPB-111077 and decitabine may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as venetoclax, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving STAT inhibitor OPB-111077, decitabine, and venetoclax may work better in treating patients with acute myeloid leukemia compared to decitabine alone.

PRIMARY OBJECTIVE:

I. To determine the safety and tolerability of STAT inhibitor OPB-111077 (OPB-111077) in combination with decitabine and venetoclax.

SECONDARY OBJECTIVES:

I. To describe any preliminary efficacy of OPB-111077 in combination with decitabine and venetoclax in patients with acute myeloid leukemia (AML).

II. To measure adenosine triphosphate (ATP) generation and perform metabolomics in patients with AML who are receiving OPB-111077, decitabine, and venetoclax.

III. To assess apoptosis and proliferation assays in patients with AML who are receiving OPB-111077, decitabine, and venetoclax.

OUTLINE: This is a dose escalation study of STAT inhibitor OPB-111077.

INDUCTION CYCLE 1: Patients receive STAT inhibitor OPB-111077 orally (PO) once daily (QD) on days 1-28, and venetoclax PO QD on days 4-28 of cycle 1. Patients also receive decitabine intravenously (IV) over approximately 1 hour on days 4-8 of cycle 1. Patients who achieve complete remission (CR) after 1 cycle move on to Maintenance, and patients who do not achieve a CR move on to Cycle 2.

INDUCTION CYCLE 2: Patients receive STAT inhibitor OPB-111077, venetoclax, and decitabine as in Induction Cycle 1. Patients who achieve CR, complete remission with incomplete hematologic recovery (CRi), partial remission (PR), or stable disease (or clinically significant hematologic improvement as determined by the investigator) move on to Maintenance.

MAINTENANCE: Patients receive STAT inhibitor OPB-111077, venetoclax, and decitabine as in Induction Cycle 1. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for 2 years.

Creatinine clearance (CrCL) >= 45
Total bilirubin =< 2 x upper limit of normal (ULN)
Serum glutamate pyruvate transaminase (SGPT) alanine aminotransferase (ALT) =< 2 x ULN
Negative pregnancy test for women with child-bearing potential
Patients must be able to sign consent and be willing and able to comply with scheduled visits, treatment plan and laboratory testing

Exclusion Criteria:

Subjects with FAB M3 (t(15;17)(q22;q21)[PML-RARalpha]) are not eligible
Subjects must not be receiving any chemotherapy agents (except hydroxyurea); intrathecal methotrexate and cytarabine are permissible
Subjects must not be receiving growth factors, except for erythropoietin
Subjects with a "currently active" second malignancy, other than non-melanoma skin cancer, carcinoma in situ of the cervix, resected incidental prostate cancer (staged pT2 with Gleason score =< 6 and postoperative prostate-specific antigen [PSA] < 0.5 ng/mL), or other adequately treated carcinoma-in-situ are ineligible; patients are not considered to have a "currently active" malignancy if they have completed therapy and are free of disease for >= 1 year
Subjects with uncontrolled high blood pressure, unstable angina, symptomatic congestive heart failure (New York Heart Association [NYHA] class 3), myocardial infarction within the past 6 months or serious uncontrolled cardiac arrhythmia are not eligible
Subjects with other severe concurrent disease which in the judgment of the investigator would make the patient inappropriate for entry into this study are ineligible
Subjects must not have evidence of active leukemia in the central nervous system (CNS)
Subjects must not have received any investigational agents within 14 days or 5 half-lives (whichever is longer) of study entry
Subjects must not be pregnant or breastfeeding; pregnancy tests must be obtained for all females of child-bearing potential; pregnant or lactating patients are ineligible for this study; males or women of childbearing potential may not participate unless they have agreed to use an effective contraceptive method (defined as hormonal contraceptives, intrauterine devices, surgical contraceptives, or condoms)
Subjects who have uncontrolled infection are not eligible; patients must have any active infections under control; fungal disease must be stable for at least 2 weeks before study entry
Subjects with bacteremia must have documented negative blood cultures prior to study entry
Subjects who are suitable for and willing to receive standard intensive induction therapy
Subjects who are candidates for allogeneic transplantation, have a suitable donor, and are willing to undergo transplantation
