At least 4 weeks since last chemotherapy, radiotherapy, biologic therapy or surgery
Must be free of post-treatment side effects (with the exception of alopecia)
No concurrent chemotherapy, biologic therapy or radiotherapy is allowed
Hemoglobin = 9.0 g/dL
WBC = 3,500/mm3 [= 3.5 x 109/L]
Neutrophils = 1,500/mm3 [= 1.5 x 109/L]
Platelets = 100,000/mm3 [= 100.0 x 109/L]
Calculated creatinine clearance=60 mL/min using the Cockcroft-Gault formula

If liver metastases are present, subjects with < 5 times the upper limit of normal are eligible to participate

Exclusion criteria

Women who are pregnant or lactating
Women subjects of childbearing potential who refuse to abstain from sexual intercourse or practice adequate contraception. Childbearing potential is defined as women who are not surgically sterilized (i.e. have not had a hysterectomy, bilateral oophorectomy [ovariectomy], or bilateral tubal ligation) or post-menopausal (i.e., documented absence of menses for one year prior to entry into the study).
Men unwilling to abstain from sex or use effective contraception during the study and for 3 months following completion of topotecan treatment
Subjects with uncontrolled emesis, regardless of etiology
Active infection
Concurrent severe medical problems unrelated to the malignancy, which would significantly limit full compliance with the study or expose the patient to extreme risk
Treatment with another investigational drug within 30 days or five half-lives prior to entry into the study (whichever is longer)
History of allergic reactions to compounds chemically related to topotecan.
