Overview

Study Safety and Preliminary Efficacy of DCC-2036 in Patients With Leukemias (Ph+ CML With T315I Mutation)

Status:
Completed
Trial end date:
2013-01-01
Target enrollment:
0
Participant gender:
All
Summary
Rationale: DCC-2036 is a potent broad spectrum inhibitor of BCR-ABL kinase. Inhibition of BCR-ABL has been validated for effective treatment of chronic myeloid leukemia (CML). The emergence of mutant forms of BCR-ABL which resist inhibition by imatinib, dasatinib, and nilotinib is associated with loss of efficacy in treatment of the disease. DCC-2036 is a potent inhibitor of resistant mutants of BCR-ABL including the T315I mutation, and would therefore be expected to effectively treat patients who fail to respond to other BCR-ABL inhibitors. DCC-2036 also inhibits FLT3-ITD, TIE2, KDR, LYN and TRKA kinases. Purpose: to assess the safety and tolerability in patients after continuous administration of DCC-2036 and to determine recommended doses for the conduct of a Phase 2 efficacy trial.

Criteria
Inclusion Criteria: Subjects must meet all of the following inclusion criteria to be
eligible:

- Ph+ CML in Chronic Phase with T315I mutation

- 18 years or older

- The subject has an ECOG performance status of ≤ 2.

- Adequate organ function as indicated by the following laboratory assessments performed
within 14 days prior to the first dose of study drug Hepatic: Serum bilirubin ≤1.5
times upper limit (X ULN) of normal unless due to leukemic involvement or Gilbert's
syndrome; aspartate aminotransferase or alanine aminotransferase ≤ 2.5 X ULN; alkaline
phosphatase ≤ 2.5 X ULN Renal: Serum creatinine ≤ 1.5 X ULN or 24 hour creatinine
clearance ≥ 50 mL/min

- Female subjects of childbearing potential must have a negative serum or urine
beta-human chorionic gonadotropin pregnancy test within 14 days prior to the start of
study drug

- Sexually active subjects who are fertile must agree to use an effective barrier method
of contraception while on therapy and for 30 days following discontinuation of study
drug. Non-fertile subjects or those not sexually active are also eligible.

- The subject is capable of understanding and complying with the protocol and has signed
the informed consent document.

Exclusion Criteria: Subjects presenting with any of the following will not qualify for
entry into the study:

- Subject has received chemotherapy or a TKI ≤ 7 days, investigational agent ≤ 14 days,
or radiotherapy ≤ 28 days prior to the start of study drug or has not recovered from
the acute toxicities associated with any prior treatments including approved
therapies, investigational agents, and prior stem cell or bone marrow transplant. The
following exceptions apply: i) Hydroxyurea is permitted at any time prior to study
enrollment; ii) Glucocorticoids (natural or synthetic) are allowed up to 48 hours
prior to the start of the study drug (with the exception of steroids for
pre-medication and topical/nasal steroid use which are allowed at any time)

- The subject has AP or BP-CML

- Received immunosuppressive therapy ≤ 28 days prior to the first dose of study drug

- NY Heart Association class III or IV heart disease, active ischemia or any other
uncontrolled cardiac condition such as angina pectoris, clinically significant cardiac
arrhythmia requiring therapy, uncontrolled hypertension or congestive heart failure

- Myocardial infarction within 3 months of the start of study drug

- Active, uncontrolled systemic infection considered opportunistic, life threatening, or
clinically significant

- Any other severe concurrent disease and/or uncontrolled medical conditions, which in
the judgment of the investigator, could predispose subjects to unacceptable safety
risks or compromise compliance with the protocol

- Human immunodeficiency virus positive

- If female, the subject is pregnant or lactating

- Allergic or hypersensitive to any component of the investigational drug product
