Brief Summary:
This pilot clinical trial studies 6, 8-bis (benzylthio) octanoic acid (CPI-613) in treating patients with myelodysplastic syndromes who failed previous therapy. Sometimes when chemotherapy or biological therapy is given, it does not stop the growth of tumor cells. The tumor is said to be resistant to treatment. 6, 8-bis (benzylthio) octanoic acid may interfere with the growth of tumor cells and may be an effective treatment for myelodysplastic syndromes that did not respond to previous therapy.

Condition or disease Intervention/treatment Phase
Previously Treated Myelodysplastic Syndromes Drug: 6,8-bis(benzylthio)octanoic acid Phase 2

Detailed Description:


I. To evaluate the safety and anti-cancer activities of CPI-613 in myelodysplastic syndrome (MDS) patients who have failed previous agents (such as decitabine [Dacogen], azacitidine [Vidaza], growth factors or lenalidomide).


Patients receive 6, 8-bis (benzylthio) octanoic acid intravenously (IV) over 2 hours on days 1 and 4 of weeks 1-3. Courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for 5 years.

Arm Intervention/treatment
Experimental: Treatment (6, 8-bis(benzylthio) octanoic acid)
Patients receive treatment 6,8-bis(benzylthio)octanoic acid IV over 2 hours on days 1 and 4 of weeks 1-3. Courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity.
Drug: 6,8-bis(benzylthio)octanoic acid
Given IV
Other Names:
  • alpha-lipoic acid analogue CPI-613
  • CPI-613

Primary Outcome Measures :
  1. Response rate (RR), defined as the combined rate of complete remission (CR), marrow CR, partial remission (PR), or stable disease (SD), as described by Cheson, et al. (2006) [ Time Frame: Up to 5 years ]
    Proportion of RR (along with a 95% confidence interval) of patients who respond will be presented.

Secondary Outcome Measures :
  1. Safety profile of CPI-613, based on evaluation of symptoms, vital signs, ECOG performance status and survival, clinical chemistry, hematology, and coagulation, assessed by National Cancer Institute Common Terminology Criteria for Adverse Events v 4.0 [ Time Frame: Up to 1 month post-treatment ]
    Toxicities will be examined by looking at each toxicity identified by grade.

  2. Progression-free survival (PFS) [ Time Frame: Up to 5 years ]
    Survival curves for PFS using Kaplan-Meier techniques will be estimated. In addition, the 6 month and 1-year PFS rates for these participants will be estimated.

  3. Overall survival (OS) [ Time Frame: Up to 5 years ]
    Survival curves for OS using Kaplan-Meier techniques will be estimated. In addition, the 6 month and 1-year OS rates for these participants will be estimated.

  4. Number of patients who achieve a reduction in blood transfusion requirements [ Time Frame: Up to 5 years ]
  5. Number of patients who achieve hematologic improvement (HI), as defined by Cheson, et al. (2006) [ Time Frame: Up to 5 years ]

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Histologically or cytologically documented MDS of any risk group that has failed previous therapy (therapy failure is defined as patients who have been sufficiently treated with previous agents without response in the opinion of the treating physician, or whose disease has progressed or relapsed while on a hypomethylating agent)
  • Eastern Cooperative Oncology Group (ECOG) performance status of =< 3
  • Expected survival > 2 months
  • Women of child-bearing potential (i.e., women who are pre-menopausal or not surgically sterile) must use accepted contraceptive methods (abstinence, intrauterine device [IUD], oral contraceptive or double barrier device) during the study, and must have a negative serum or urine pregnancy test within 1 week prior to treatment initiation
  • Fertile men must practice effective contraceptive methods during the study, unless documentation of infertility exists
  • Patients must have fully recovered from the acute, non-hematological, non-infectious toxicities of any prior treatment with cytotoxic drugs, radiotherapy or other anti-cancer modalities; patients with persisting, non-hematologic, non-infectious toxicities from prior treatment =< grade 2 are eligible, but must be documented as such
  • Aspartate aminotransferase (AST/serum glutamic oxaloacetic transaminase [SGOT]) =< 3 x upper normal limit (UNL)
  • Alanine aminotransferase (ALT)/serum glutamate pyruvate transaminase (SGPT) =< 3 x UNL (=< 5x ULN if liver metastases present)
  • Bilirubin =< 1.5 x UNL
  • Serum creatinine =< 1.5 mg/dL or 133 umol/L
  • International normalized ratio (or INR) must be < 1.5
  • Albumin >= 2.0 g/dL or >= 20 g/L
  • Mentally competent, ability to understand and willingness to sign an Institutional Review Board (IRB)-approved written informed consent form
  • Have access via central line (e.g., portacath)

Exclusion Criteria:

  • Serious medical illness, such as significant cardiac disease (e.g. symptomatic congestive heart failure, unstable angina pectoris, coronary artery disease, myocardial infarction within the past 3 months, uncontrolled cardiac arrhythmia, pericardial disease or New York Heart Association class III or IV), or severe debilitating pulmonary disease, that would potentially increase patients' risk for toxicity
  • Patients with active central nervous system (CNS) or epidural tumor
  • Any active uncontrolled bleeding or bleeding diathesis (e.g., active peptic ulcer disease)
  • Any condition or abnormality which may, in the opinion of the investigator, compromise his or her safety
  • Pregnant women, or women of child-bearing potential not using reliable means of contraception
  • Fertile men unwilling to practice contraceptive methods during the study period

  • Requirement for immediate palliative treatment of any kind including surgery
  • Prior illicit drug addiction
  • Patients with large and recurrent pleural or peritoneal effusions requiring frequent drainage (e.g. weekly)
  • Patients with any amount of clinically significant pericardial effusion
  • Patients with known human immunodeficiency virus (HIV) infection; (Note: patients with known HIV infection are excluded because patients with an immune deficiency are at increased risk of lethal infections when treated with marrow-suppressive therapy, and because there may be unknown or dangerous drug interactions between CPI-613 and anti-retroviral agents used to treat HIV infections)
  • Patients who have received radiotherapy, surgery, treatment with cytotoxic agents (except CPI-613), treatment with biologic agents, immunotherapy, or any other anti-cancer therapy of any kind, or any other standard or investigational treatment for their cancer, or any other investigational agent for any indication, within the past 2 weeks prior to initiation of CPI-613 treatment
