재발성 또는 난치성 급성 골수성 백혈병 환자를 치료하는 8-클로로데노신

2026년 10월 15일 업데이트: City of Hope Medical Center

재발성 또는 불응성 급성 골수성 백혈병에서 8-클로로-아데노신의 I/II상 시험

This phase I/II trial studies the side effects and best dose of 8-chloroadenosine and to see how well it works in treating patients with acute myeloid leukemia that has returned after a period of improvement (relapsed) or does not respond to treatment (refractory). Drugs used in chemotherapy, such as 8-chloroadenosine, 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.

연구 개요

상세 설명

PRIMARY OBJECTIVES:

I. To determine the maximum tolerated dose (recommended phase II dose, RP2D) of 8-chloro-adenosine, when given as a single agent, in patients with relapsed or refractory acute myeloid leukemia. (Phase I) II. To assess tolerability and safety of 8-chloro-adenosine at each dose level by evaluation of toxicities including: type, frequency, severity, attribution, time course and duration. (Phase I) III. To estimate the response rate and to evaluate the antitumor activity of 8-chloro-adenosine, when given as a single agent, as assessed by complete remission rate (complete remission [CR] + complete remission with incomplete blood count recovery [CRi]). (Phase II)

SECONDARY OBJECTIVES:

I. To evaluate for disease response to 8-chloro-adenosine in refractory/relapsed acute myeloid leukemia (AML) on each dose level tested. (Phase I) II. To obtain estimates of remission duration and survival probabilities (overall and event-free). (Phase II) III. To obtain an estimate of the overall response rate (CR + CRi + partial response [PR]). (Phase II) IV. To summarize and evaluate toxicities by type, frequency, severity, attribution, time course and duration. (Phase II)

CLINICAL PHARMACOLOGY OBJECTIVES:

I. To describe the plasma, urinary and cellular pharmacokinetics of 8-chloro-adenosine and metabolites.

II. To determine the impact of 8-chloro-adenosine on cellular adenosine triphosphate (ATP) pool in AML blasts.

III. To assess the impact of 8-chloro-adenosine therapy on select short-lived messenger (m) ribonucleic acids (RNAs) and corresponding proteins in circulating AML blasts.

IV. To correlate clinical responses and toxicity with plasma/urine 8-chloro-adenosine level (pharmacokinetic [PK]), cellular 8-chloro-ATP (PK) and cellular ATP pool.

EXPLORATORY EX-VIVO MOLECULAR OBJECTIVES:

I. To determine the cytotoxicity of 8-chloro-adenosine toward leukemic progenitor cells in vitro.

II. To generate a preliminary pre-treatment RNA/micro RNA (miRNA) signature in leukemic progenitor cells, and explore its possible association with in vitro cytotoxicity to 8-chloro-adenosine.

III. To explore the possible association between the preliminary RNA/miRNA signature and clinical response to 8-chloro-adenosine.

OUTLINE: This is a phase I, dose-escalation study followed by a phase II study.

Patients receive 8-chloro-adenosine intravenously (IV) over 4 hours on days 1-5. Treatment repeats every 28 days for up to 4 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days and then every 3 months for up to 2 years.

    • Patients who have relapsed after allogeneic hematopoietic cell transplant (HCT) are eligible if they are at least 3 months after HCT, do not have active graft vs. host disease (GVHD) and are off immunosuppression except for maintenance dose of steroids (prednisone 10 mg/day or less)
  • At least 2 weeks from prior chemotherapy or radiation therapy to time of start of treatment, except for hydroxyurea or corticosteroid therapy which may be continued through cycle 1

  • Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =< 2.5 x upper limit of normal (ULN)

  • Total bilirubin =< 1.5 X ULN

  • Corrected QT (QTc) =< 480 ms

  • Calculated creatinine clearance (CrCl) >= 50 mL/min per 24 hour urine collection or the Cockcroft-Gault formula

  • Negative serum or urine beta-human chorionic gonadotropin (beta-HCG) test (female of childbearing potential only), to be performed locally within the screening period

  • Agreement by females of childbearing potential and sexually active males to use an effective method of contraception (hormonal or barrier method of birth control or abstinence) prior to study entry and for three months following duration of study participation; the effects of study treatment on a developing fetus have the potential for teratogenic or abortifacient effects; should a woman become pregnant or suspect that she is pregnant while participating on the trial, she should inform her treating physician immediately

Exclusion Criteria:

  • Current or planned use of other investigational agents, or concurrent biological chemotherapy, or radiation therapy during the study treatment period
  • Expected to undergo HCT within 120 days of enrollment
  • Current or planned use of agents that prolong or suspected to prolong QTc
  • Diagnosis of acute promyelocytic leukemia
  • Active central nervous system leukemia
  • Active fungal infection or bacterial sepsis
  • Active peptic ulcer disease
  • History of heart failure or cardiac arrhythmia
  • Other active malignancy except for localized skin cancer, bladder, prostate, breast or cervical carcinoma in situ
  • Pregnant women and women who are lactating; 8-chloro-adenosine is an agent with the potential for teratogenic or abortifacient effects; because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with 8-chloro-adenosine, breastfeeding should be discontinued if the mother is treated with 8-chloro-adenosine
  • Any other condition that would, in the investigator's judgment, contraindicate the patient's participation in the clinical study due to safety concerns or compliance with clinical study procedures
  • Prospective participants who, in the opinion of the investigator, may not be able to comply with all study procedures (including compliance issues related to feasibility/logistics)

주요 결과 측정

결과 측정
측정값 설명
기간
Recommended Phase II Dose (RP2D) of 8-Chloro-adenosine (8-Cl-Ado)
기간: Up to 28 days following first study agent administration.

According to the standard 3+3 rules, where the highest DL that produced ≤ 1/6 DLTs in cycle 1 would be defined as the maximum tolerated dose (MTD). The RP2D of 8-Cl-Ado would generally be the MTD, but it could be less than the initially calculated MTD as determined from a review of the available data and cumulative toxicities from phase 1.

Up to 28 days following first study agent administration.
Dose Limiting Toxicity (DLT)
기간: Up to 28 days following first study agent administration.

Toxicity was graded according to the NCI-Common Terminology Criteria for Adverse Events version 4.03. A DLT was defined as any of the following toxicities (please see the details in section of 13.2 of the protocol) that occur during cycle 1, per CTCAE version 4.03, and were considered related to the study drug.

Up to 28 days following first study agent administration.
