Brief Summary:

The study is a multicenter, open label Phase I/II trial.

  1. To determine the maximum tolerated dose (MTD) of lintuzumab-Ac225 added to venetoclax for patients with CD33 positive relapsed/refractory AML. (Phase 1 portion)
  2. To assess the percentage of patients with CR, CRh, or Overall Response (CR + CRh), up to 6 months after the start of treatment without receiving other AML therapies. (Phase 2 portion)

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 38 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase I/II Study of Venetoclax and Lintuzumab-Ac225 in Patients With Refractory or Relapsed AML
Estimated Study Start Date : December 2019
Estimated Primary Completion Date : November 2020
Estimated Study Completion Date : November 2022


Arm Intervention/treatment
Experimental: Phase I and Phase II

Lintuzumab-Ac225 administered on Day 1 of each cycle for four cycles (unless in the 0.5 μCi/kg or 0.25 μCi/kg cohorts, where there is a potential for an additional four cycles, pending PI and Medical Monitor review).

Venetoclax taken on Days 1-21 of each cycle for up to 12 cycles.

Each cycle is 28 days, with a potential to expand to 42 days to allow for full hematologic recovery.

Biological: Lintuzumab-Ac225
In the Phase I, patients will be enrolled into the following dose escalation cohorts: 0.50 μCi/kg, 1.0 μCi/kg, and 1.5 μCi/kg. If the 0.50 μCi/kg dose is determined to exceed the MTD, a 0.25 μCi/kg dose will be explored.
Other Name: Actimab

Drug: Venetoclax
400 mg daily will be taken orally on Days 1-21 of a 28-day cycle. There will be a ramp up of venetoclax dosing in the first cycle, with 100 mg administered on Day 1, 200 mg on Day 2, and 400 mg on Day 3 and Day 4 and later. Patients on antifungal azoles should receive one-half these doses, up to a maximum of 200 mg of venetoclax.
Other Name: Venclexta

Drug: Spironolactone
25 mg by mouth daily, administered on Cycle 1 Day 15 and continued for 12 months after the subject's last treatment with lintuzumab-Ac225.
Other Name: Aldactone




Primary Outcome Measures :
  1. Phase I: Maximum Tolerated Dose (MTD) of Lintuzumab-Ac225 [ Time Frame: Cycle 1, up to 48 days ]
    To determine the maximum tolerated dose (MTD) of lintuzumab-Ac225 added to venetoclax for patients with CD33 positive relapse/refractory AML.

  2. Phase II: Overall Response (CR + CRh) [ Time Frame: Up to 6 months ]
    To assess the percentage of patients with CR, CRh, or Overall Response (CR + CRh), up to 6 months after the start of treatment without receiving other AML therapies.


Secondary Outcome Measures :
  1. Phase I: Overall Response [ Time Frame: Up to 6 months ]
    Number of patients who's overall response is CR or CRh

  2. Phase I and II: OS [ Time Frame: End of 6 months, 12 months, 2 years ]
    Number of patients who died

  3. Phase I and II: DFS [ Time Frame: End of 6 months, 12 months, 2 years ]
    Disease-free survival

  4. Phase I and II: Evaluate incidence of AEs and SAEs [ Time Frame: Through study completion, up to 2 years ]
    Rate of AEs and SAEs, including infusion-related reactions

  5. Phase I and II: Evaluate BH3 priming assay results [ Time Frame: Completion of Cycle 1, estimated 1 month ]
    Summary of assay results

  6. Phase I and II: MRD status [ Time Frame: From date of first dose until the date of first documented response, first assessment at 6 months ]
    Number of patients who are MRD negative

  7. Phase I and II: Lab abnormalities (other than hematologic indices) [ Time Frame: Through study completion, up to 2 years ]
    Summary of rate of Grade 3/4 lab abnormalities

Criteria

Inclusion Criteria:

  1. Refractory or relapsed AML which will include:

    1. Refractory disease will be defined as at least 1 prior treatment with no remission.
    2. Relapsed disease will be defined as 5% or more blasts in bone marrow seen after remission.
    3. Patients with AML arising from myelodysplastic syndromes (including CMML) or myeloproliferative neoplasms (secondary AML, ts-AML) are also eligible.
  2. Circulating blast count ≤ 200/μL within 10 days prior to first cycle of treatment. Hydroxyurea should be used to keep the peripheral blast count ≤ 200/μL until the first day of protocol treatment, to the extent that this is possible
  3. ECOG ≤ 2
