Description

Inclusion Criteria:

• Diagnosis of advanced solid malignancy refractory to prior therapy and unlikely to benefit from known therapies (e.g., chemotherapy, radiation therapy, and surgery).
• Diagnosis confirmed histologically or cytologically.
• Subjects may have received prior cancer therapy (including surgery, radiotherapy, chemotherapy, and hormonal therapy), but must have completed all therapies at least 30 days prior to study drug administration (42 days for nitrosourea or mitomycin).
• Subjects must have recovered from the toxic effects associated with prior treatment.
• Subjects must have an Eastern Cooperative Oncology Group performance status of ≤ 2 and an estimated life expectancy of at least 12 weeks.
• Subjects must have adequate organ and immune function as indicated by standard laboratory tests.
• The subject must understand, be able, willing, and likely to fully comply with study procedures, including scheduled follow-up, and restrictions.
• The subject must give written, personally signed and dated, informed consent to participate in the study before implementing any study related procedures.

Exclusion Criteria:

• Previously documented brain metastases.
• Active and uncontrolled infection.
• Subjects with uncontrolled medical problems, unrelated to the malignancy, or of sufficient severity that in the opinion of the investigator, impair their ability to give informed consent or unacceptably reduce the safety of the proposed treatment.
• Neurological or psychiatric disorders that would interfere with consent or study follow-up.
• Prior treatment with more than 6 courses of alkylating agent-containing chemotherapy (except low-dose cisplatin) or more than 4 courses of carboplatin, radiation therapy to > 25% of hematopoietic reserves or two or more courses of mitomycin C or nitrosourea.
• Known or suspected intolerance or hypersensitivity to the study materials [or closely related compounds] or any of their stated ingredients.
• History of alcohol or other substance abuse within the last year.
• Use of another investigational agent or participation in a clinical trial within 30 days prior to enrollment.
• Female subjects who are pregnant or lactating, including females with a positive pregnancy test at screening must be excluded.
• Subjects that have previously been enrolled into this study and subsequently withdrawn must also be excluded.
