About

The purpose of this phase II study is to assess the efficacy of AP23573 in patients with specified relapsed or refractory hematological malignancies.

Full description

The primary objective of the trial is to assess the efficacy of AP23573 in patients with specified relapsed or refractory hematological malignancies by evaluating the response rates as defined for the individual malignancy categories. Secondary objectives include evaluating time to disease progression, progression-free survival and duration of response; evaluating the pharmacokinetic and pharmacodynamic characteristics of AP23573; describing health-related quality of life measurements; and exploring the safety and tolerability of AP23573 at the specified dose level.

Protocol Outline: Open label, non-randomized parallel cohorts of five disease-specific cohorts with a minimum of 21 patients per cohort. Each patient receives a fixed dose of AP23573 administered intravenously (IV) over 30 minutes daily for five days (QDx5) to be repeated every 2 weeks.

Patients must have histologically-confirmed diagnoses of relapsed or refractory hematologic malignancy as specified in the protocol
Patients must have an ECOG performance status of 0 to 2
Patients must have adequate renal and liver function as demonstrated by laboratory values performed within 5 days, inclusive, prior to administration of the first dose of AP23573
Patients must be able to understand and give written informed consent

Exclusion Criteria (Patients meeting any of the following criteria are ineligible for participation in the study):

Women who are pregnant or lactating
Patients may not have had cytotoxic chemotherapy or radiotherapy within 14 days prior to study entry
Patients may not receive any investigational anti-cancer agent while on this study or within 14 days prior to the first dose of AP23573
Patients with known or suspected hypersensitivity to drugs formulated with polysorbate 80 (Tween) or any other excipient contained in the study drug formulation
Patients with known Grade 3 or 4 hypersensitivity to macrolide antibiotics (e.g., clarithromycin, erythromycin, azithromycin)
Patients with significant uncontrolled cardiovascular disease
Patients with known HIV infection
Patients with any uncontrolled infection
Patients receiving immunosuppressive agents other than prescribed corticosteroids
Patients who have had prior therapy with rapamycin, any rapamycin analog or tacrolimus
Patients with inadequate recovery from any prior surgical procedure or patients having undergone any major surgical procedure within 14 days prior to the first dose of AP23573
Patients with any other life-threatening illness or organ system dysfunction which, in the opinion of the Investigator, would either compromise the patient's safety or interfere with evaluation of the safety of the study drug
Patients with a psychiatric disorder or altered mental status that would preclude understanding of the informed consent process and/or completion of the necessary studies
Patients with another primary malignancy within the past three years (except for non-melanoma skin cancer and cervical carcinomas in situ)
Patients with the inability, in the opinion of the Investigator, to comply with the protocol requirements

Drugs and Other Treatments to be Excluded (The following drugs and other treatments are not permitted for patients enrolling in the study, either during or within two weeks prior to the first dose of AP23573, unless otherwise specified):

Chemotherapeutic agents with the following exception that therapy with nitrosoureas (including generics) cannot be given within six weeks prior to the first dose of AP23573
Other antineoplastic agents
Immunotherapy (including vaccines) or biological response modifier therapy
Systemic hormonal therapy with exceptions as specified in the protocol
Herbal preparations or related OTC preparations containing herbal ingredients (e.g., St John's Wort)
Radiotherapy for the primary malignancy
Any other investigational agent during the course of the trial should be discussed with the Sponsor prior to use
