研究概览
简要总结
The purpose of this study is to assess the safety and efficacy of Amonafide in men with androgen-independent prostate cancer, assigned to individualized doses of Amonafide based on acetylator phenotype information (doses adjusted on individual metabolism).
详细描述
This is an open-label, Phase I/II, multicenter study of Amonafide in subjects with androgen-independent metastatic prostate cancer.
Amonafide is metabolized by N-acetylation to an active metabolite, N-acetyl-Amonafide. Inter-subject differences in N-acetylation can explain the variability in Amonafide-induced myelosuppression. This dose-defining protocol has been designed to assess safety and efficacy of Amonafide in men with androgen-independent prostate cancer, assigned to individualized doses based on acetylator phenotype information.
The total duration of this study will be approximately 12 - 16 months: approximately 6 - 10 months for enrollment, and approximately 6 months for subject screening, treatment, and follow up per protocol. Subjects will be treated until PSA progression, disease progression, or unacceptable toxicity.
Subjects may continue participation in the study after Cycle 5 at the investigator's discretion if PSA progression, disease progression, or unacceptable toxicities are not reported. If a subject fulfills a criterion of PSA progression or disease progression, yet in the opinion of the investigator, the subject appears to be deriving clinical benefit from the study medication, a request may be made to the Xanthus medical monitor to allow that subject to continue study participation on a compassionate basis.
A follow-up evaluation for all subjects will be done 30 - 35 days after receiving the last dose of Amonafide. Subjects will be contacted every 3 months for survival after completion of the active phase of the study, until death.

- •Subjects must have recovered from all acute toxicities from prior treatment;
- •Screening visit phenotyping procedures must have been completed successfully;
- •No blood transfusion within the previous 2 weeks of signature of the informed consent;
- •Expected cooperation of the subject for the treatment and follow up must be obtained and documented;
- •Written informed consent must be obtained and documented.
排除标准
- •Clinically significant abnormal hematological parameters other than those defined in the inclusion criteria;
- •Clinically significant abnormal biochemical parameters other than those defined in the inclusion criteria;
- •Subjects who have been receiving bisphosphonates for less than three months prior to the first Amonafide administration;
- •Known history of brain metastases;
- •Subjects who are HIV positive;
- •Subjects who are hepatitis B surface antigen positive or have previously documented hepatitis C infection;
- •Subjects who received treatment with Growth Factors (i.e. G-CSF, GM-CSF) within 2 weeks of the signature of the informed consent form;
- •Subjects who had any major surgery within four weeks of first administration of Amonafide;
- •Subjects with a history of a psychological illness or condition which may interfere with the subjects ability to understand or comply with the requirements of the study;
- •Subjects who received an investigational new drug within 30 days of the first dose of Amonafide;
- •Any other known condition, which in the investigator's opinion would not make the subject a good candidate for the trial.
结局指标
主要结局
The Primary Objectives of this study are:
To define and validate the safety of a NAT2 pheontypically driven dosing regimen;
To define the pharmacokinetic and pharmacodynamic profile of Amonafide with a weekly intravenous administration schedule.
次要结局
- The Secondary Objectives of this study are:
- To determine the efficacy of weekly intravenous Amonafide for all enrolled subjects as defined by PSA response (decrease in PSA of 50% or greater), duration of PSA response, and time to PSA progression;
- To determine the overall tumor response (e.g., complete response or partial response), duration of tumor response, and time to tumor progression among subjects with measurable lesions using standard (RECIST) criteria.
