研究概览
简要总结
This is a Phase I/II single site, open label clinical trial. The purpose of the Phase I portion is to determine the safety, tolerability, and recommended Phase II dose of Eicosapentaenoic Acid (EPA) when given daily in combination with a Tyrosine Kinase Inhibitor (TKI) in subjects with Chronic Myeloid Leukemia (CML) in chronic stable phase. The recommended Phase II dose will be the maximum tolerated dose (MTD) of EPA as determined by the evaluation of dose-limiting toxicities (DLTs). The Phase II portion will subsequently examine the Anti-CML effects of EPA when administered with a TKI at the recommended Phase II dose. This efficacy objective will be done by evaluating BCR-ABL p210 quantitative PCR blood levels every 3 months to 1 year.
详细描述
Targeting CML leukemia stem cells is of paramount importance in successfully preventing cancer relapse. EPA metabolite, Δ12-PGJ3 may represent a new chemotherapeutic agent for leukemia that targets leukemia stem cells. Selective targeting of cancer stem cells may be potentially a highly effective treatment for cancer. As most CML patients treated with a TKI will reach a complete cytogenetic response, quantification of residual BCR-ABL transcripts by quantitative reverse transcription PCR (RT-qPCR) is a critical tool to further monitor response kinetics. Addition of EPA to TKI may help decrease residual BCR-ABL positive (Ph+) leukemia stem cells.

入选标准
- •Male or female ≥18 years of age.
- •Confirmed diagnosis of CML ≥ 18 months from diagnosis.
- •Current concomitant treatment with TKI therapy (Imatinib, Dasatinib, Nilotinib or Bosutinib; excluding Ponatinib). TKI therapy should be stable (same drug and dose) for at least 3 months prior to study enrollment.
- •One of the following confirmed:
- •BCR-ABL p210 at stable molecular disease (e.g., MMR stable but not CMR)
- •HR but no MMR.
- •Stable molecular response defined as 2 sequential BCR-ABL p210 levels done in the same lab with less than ½ log reduction of BCR-ABL (BA) 3-6 months apart.
- •ECOG PS of ≤ 3
- •Adequate organ function, as defined by the following:
- •ANC ≥ 500 cells/mm3 Platelet count ≥ 50,000 cells/mm3 Serum bilirubin ≤ 1.5 x ULN AST and ALT ≤ 2.5 x ULN Alkaline phosphatase ≤ 2.5 x ULN
- •WOCP as defined as defined as not surgically sterile or not one year post-menopausal, must have a negative result for a serum or urine pregnancy test within 7 days of initial receipt of study drug. Surgically sterile is defined as having had a hysterectomy, tubal ligation, or oophorectomy.
- •WOCP must use a medically accepted method of contraception and must agree to continued use of this method for the duration of the study and for 30 days after last dose of study drug. Acceptable methods of contraception include abstinence, barrier method with spermicide, intrauterine device (IUD) known to have a failure rate of less than 1% per year, or steroidal contraceptive (oral, transdermal, implanted, or injected) in conjunction with a barrier method.
- •Male subjects capable of producing offspring, must use a medically accepted method of birth control and agree to continued use of this method for the duration of the study and for 30 days after last dose of study drug because of the possible effects on spermatogenesis. Acceptable methods of contraception include abstinence, barrier method with spermicide, WOCP partner's use of an IUD known to have a failure rate of less than 1% per year, WOCP partner's use of steroidal contraceptive (oral, implanted or injected) in conjunction with a barrier method, WOCP partner is surgically sterile or 1 year postmenopausal. In addition, male subjects may not donate sperm for the duration of the study and for 30 days after last dose of study drug.
排除标准

研究组 & 干预措施
Eicosapentaenoic Acid (EPA)
Phase I: TKI with escalating/de-escalating doses of EPA to determine MTD.
Phase I dose levels: Dose Level 1 = EPA 1500 mg orally once per day; Dose Level 2 = EPA 2000 mg orally once per day; Dose Level 3 = EPA 3000 mg orally once per day; Dose Level -1 = EPA 1000 mg orally once per day; Dose Level -2 = EPA 500 mg orally once per day.
Phase II: TKI administered in combination with the recommended Phase II dose of EPA
干预措施: Eicosapentaenoic Acid (Drug)

结局指标
主要结局
Phase I - Recommended Phase II Dose of EPA
时间窗: the time of initiation of the study medication to 30 days after last dose of study medication
Recommended Phase II dose of EPA will be established by using a standard 3 + 3 statistical design to determine the MTD as assessed by DLTs when administered orally in combination with a TKI in subjects with CML in stable chronic phase. Toxicity will be evaluated using the NCI Common Toxicity Criteria (CTC) version 5.0.
Phase II - Anti-CML Response to Recommended Phase II Dose Eicosapentaenoic Acid
时间窗: 1 year
BCR-ABL transcript levels will be assessed every 3 months post initiation of Eicosapentaenoic Acid to assess Anti-CML response.
次要结局
- Molecular Responses of CML(1 year)
- Induction of Apoptosis in CML Leukemia Stem Cell by Formation of Δ12-PGJ3 and Other Metabolites(2 years)
