Hematologic Malignancies AML | Drug: CP-4055 | Phase 1 Phase 2 |
This is a multicentre clinical study conducted in the USA and in Europe. It is an open label, dose escalation study designed to characterize the safety, tolerability, pharmacokinetics (PK), and efficacy of CP-4055 as a single agent when administered as a 2 hours intravenous (IV) or a continuous IV (CIV) infusion administered daily for 5 days in a 21-day cycle, either alone or with idarubicin IV, in patients with refractory/relapsed hematologic malignancies who have either failed potentially curative therapy or are considered unsuitable for standard therapy.
In a second phase of the study the efficacy of single agent CP-4055 in patients with AML may be assessed.
It is intended that patients receive a minimum of two cycles of therapy in the absence of unacceptable toxicity or significant disease progression.

Accepts Healthy Volunteers: | No |
Inclusion Criteria:
ARM A and B: Phase I CP-4055 single agent 1. Patients must have relapsed/refractory leukemias for which no standard therapies are anticipated to result in a durable response or have failed potentially curative therapy, or have refused or are considered unsuitable for standard therapy
ARM C: CP-4055 in combination with idarubicin
-
Patients with relapsed/refractory AML for which no standard therapies are anticipated to result in a durable response or who have failed potentially curative therapy, or who refuse or are considered unsuitable for standard therapy
ARM A, B, C: CP-4055 as single agent and/or in combination with idarubicin
- Patients must be 18 years of age or older
- Patients must have ECOG performance status (PS) of 0 - 2. See Appendix 3
-
Women of child-bearing potential (i.e., women who are pre-menopausal or not surgically sterile) must have a negative serum or urine pregnancy test within 2 weeks prior to beginning treatment on this study. Nursing patients are excluded.
Male and female patients must use acceptable contraceptive methods for the duration of time on study, and males also for 3 months after the last CP-4055 dose
- Patients must be capable of understanding and complying with parameters as outlined in the protocol, and able and willing to sign a written informed consent form
- In the absence of rapidly progressing disease, the interval from prior treatment to time of study drug administration should be at least 2 weeks for cytotoxic agents, or at least 5 half-lives for noncytotoxic agents.
-
Patients must have the following clinical laboratory values:
- Serum creatinine less or equal to 1.5 x the institutional upper limit of normal (ULN)
- Total bilirubin less or equal to 1.5 x the ULN unless considered due to Gilbert's syndrome
- Alanine aminotransferase (ALT) (SGPT), or aspartate aminotransferase (AST) (SGOT) less or equal to 2.5 x the ULN unless considered due to organ leukemic involvement
Phase II
1. Patients with a confirmed diagnosis of AML who have received cytotoxic chemotherapy
2 - 7. Identical to inclusion criteria nos. 2 - 7 for phase I
Exclusion Criteria:
Phase I AND II
- A history of allergic reactions or sensitivity attributed to compounds of similar chemical or biologic composition to CP-4055, i.e., ara-C and/or egg
- Known positive status for human immunodeficiency virus (HIV) or hepatitis B or C
- Pregnant and nursing patients are excluded
- Uncontrolled intercurrent illness
- Active heart disease
- Patients receiving any other standard or investigational cytotoxic treatment for their hematologic malignancy other than a maximum of 5 g of hydroxyurea to a maximum of 5 days in cycle 1 of therapy
-
Any medical condition which in the opinion of the investigator places the patient at an unacceptably high risk for toxicities
Exclusion criteria no. 8 applies only in arm C:
- Patients with hypersensitivity to idarubicin or any other component of the product, and/or other anthracyclines or anthracenediones
