Brief summary

This study is to determine the safety and recommended dosing of Minnelide in Acute Myeloid Leukemia (AML)

Detailed description

This phase 1 dose escalation clinical trial will establish the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D) of Minnelide as single-agent in relapsed/refractory (R/R) acute myeloid leukemia (AML) patients who are ineligible to receive intensive chemotherapy. The oral formulation of Minnelide will be used. Minnelide is a prodrug of triptolide (a potent heat shock protein (HSP) 70 inhibitor) with promising preclinical activity in AML.

Interventions

Patients will take Minnelide orally once daily on Days 1-21 of 28 day Cycle. Dose Escalation Schedule: Dose Level -1: .5 mg, Dose Level 1: .75 mg, Dose Level 2: 1 mg, Dose Level 3: 1.25 mg.

Inclusion criteria

* Adults ages 18 years or older. * Participant must have relapsed or refractory acute myeloid leukemia (AML) (excluding acute promyelocytic leukemia). * Relapsed patients must have received at least 1 induction chemotherapy regimen or two cycles of a hypomethylating agent and achieved a Complete Response (CR), followed by relapse of disease. * Refractory patients must have received at least 1 induction chemotherapy regimen or two cycles of hypomethylating agent without achieving a CR. * Eastern Cooperative Oncology Group (ECOG) performance status \<2. * Participants must have acceptable organ function. * Be able and willing to adhere to the study visit schedule and other protocol requirements. * Must be able to swallow capsules and have no evidence of GI tract abnormality that would alter the absorption of oral medications. * The effects of Minnelide on the developing human fetus are unknown. For this reason, women of child-bearing potential must have a negative serum or urine pregnancy test within 24 hours prior to beginning study treatment. * Participants of childbearing potential must practice contraception. Females of childbearing potential: Recommendation is for 2 effective contraceptive methods during the study. Male participants with female partners who are of childbearing potential: Recommendation is for male and partner to use at least 2 effective contraceptive methods, as described above, during the study. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately. * Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with Minnelide, breastfeeding mothers must agree to discontinue nursing if the mother is treated with Minnelide. * Provision of signed and dated informed consent document * Patients with prior allogeneic stem cell transplant who experience relapse of AML are eligible if they are off of immunosuppressive therapy and without any evidence of graft-versus-host disease (GVHD)

Exclusion criteria

* Participants may not have received any therapy with any investigational products, systemic anti-neoplastic therapy, or radiotherapy within 14 days prior to Cycle 1 Day 1. Patients actively receiving hydroxyurea are eligible and may continue to receive hydroxyurea during protocol treatment. * Candidates for standard and/or potentially curative treatments. * Major surgery within 28 days prior to Cycle 1 Day 1. * New York Heart Association Class III or IV heart failure, myocardial infarction within the past 6 months, unstable arrhythmia, or evidence of ischemia on an electrocardiogram (EKG) * Active, uncontrolled bacterial, viral, or fungal infections, requiring systemic therapy * Known, active HIV, Hepatitis A, B or C infection (prior Hepatitis C infection that has been treated and determined to be cured is allowed) * Symptomatic central nervous system (CNS) involvement with leukemia * A concurrent second active and non-stable malignancy with the exception of non-melanoma skin cancer or carcinoma in-situ.

Design outcomes

Primary

MeasureTime frameDescription
Maximum Tolerated Dose (MTD) of MinnelideUp to 28 days for each dosing cohortMTD will be determined by testing increasing doses up to 1.25 mg daily. MTD reflects highest dose of drug that did not cause a Dose Limiting Toxicity (DLT).
Number of Participants Who Experience Dose Limiting Toxicities (DLTs)Up to 28 days for each dosing cohortA DLT is any Grade 3 or 4 drug-related non-hematologic toxicity, with some exceptions per protocol.

Secondary

MeasureTime frameDescription
Complete Response (CR)Up to 12 monthsParticipants who experience Complete Response (CR) and Complete Response with Incomplete Blood Count Recovery (CRi) rate as defined by 2003 International Working Group (IWG) for AML.
Overall Response Rate (ORR)Up to 12 monthsOverall Response Rate is defined as CR + CRi + partial response (PR) as defined by 2003 IWG criteria for AML.
Relapse Free Survival (RFS)Up to 18 monthsRFS is defined as time interval between achievement of CR to time of relapse.
Overall Survival (OS)Up to 12 monthsOS defined as time interval from time of enrollment onto the clinical trial to death from any cause.
