简要总结
This study is to determine the safety and recommended dosing of Minnelide in Acute Myeloid Leukemia (AML)
详细描述
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.

入选标准
- •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 <
- •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)
排除标准
- •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
- •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
- •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.
研究组 & 干预措施
Minnelide Dose Escalation
A 3+3 design will be used. The first 3 patients will be treated at dose level 1. If none experience a Dose Limiting Toxicity (DLT), the next 3 patients will be treated at dose level 2. If a DLT is observed in 1 out of 3 patients at dose level 1, up to an 3 more patients will be enrolled and treated at that dose level. If 2 patients at dose level have DLTs, dosing will be lowered to dose level -1 (.5 mg daily, taken orally). If 2 or more of the up to 6 patients at any dose level have DLTs, the preceding dose will be declared the Maximum Tolerated Dose (MTD). If more than 1 DLT occurs at Dose Level -1, the investigators will consider stopping the study. Once the MTD has been established, an additional 10 patients will be enrolled at this level to better characterize safety and tolerability.
干预措施: Minnelide (Drug)
结局指标
主要结局
Number of Participants Who Experience Dose Limiting Toxicities (DLTs)
时间窗: Up to 28 days for each dosing cohort
A DLT is any Grade 3 or 4 drug-related non-hematologic toxicity, with some exceptions per protocol.
Maximum Tolerated Dose (MTD) of Minnelide
时间窗: Up to 28 days for each dosing cohort
MTD 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).
次要结局
- Relapse Free Survival (RFS)(Up to 18 months)
- Overall Response Rate (ORR)(Up to 12 months)
- Complete Response (CR)(Up to 12 months)
- Overall Survival (OS)(Up to 12 months)
