  Purpose
The purpose of this study is to determine the qualitative and quantitative toxicity of intrathecal topotecan, a topoisomerase I inhibitor, in patients with meningeal malignancies refractory to conventional therapy (radiation therapy and chemotherapy).

Condition Intervention Phase
Leukemia Lymphoma Meningeal Neoplasms Drug: topotecan Phase 1

Estimated Enrollment: 30
Study Start Date: February 1993
Estimated Study Completion Date: December 2000
Detailed Description:
The purpose of this study is to determine the qualitative and quantitative toxicity of intrathecal topotecan, a topoisomerase I inhibitor, in patients with meningeal malignancies refractory to conventional therapy (radiation therapy and chemotherapy). A safe dose of topotecan that can be recommended for intrathecal administration in subsequent phase II studies will be established in a limited dosage escalation schedule. The CSF pharmacokinetics of intrathecal topotecan will also be studied. Topotecan will be administered intrathecally on a bi-weekly basis for four to six weeks, followed by weekly administration for 1 month, twice monthly administration for four months and then monthly IT administration.

Criteria

DISEASE CHARACTERISTICS:

Leukemia, lymphoma, or solid tumor with overt meningeal involvement considered refractory to conventional therapy.

CSF leukemic cell count at least 5 per cubic millimeter with evidence of blast cells on cytospin or cytology required for leukemia and lymphoma patients.

Tumor cells on cytospin or cytology or measurable meningeal disease on CT or MRI required for patients with solid tumors.

No clinical evidence of obstructive hydrocephalus or compartmentalization of the CSF flow as documented by indium-111- or technetium-99-DPTA flow study.

PRIOR/CONCURRENT THERAPY:

At least 1 week since CNS therapy.

Biologic Therapy: Recovery from toxic effects of prior immunotherapy required.

Chemotherapy:

Recovery from toxic effects of prior chemotherapy required.

No concomitant therapy to treat meningeal malignancy (intrathecal or systemic).

Concomitant chemotherapy to control systemic disease or bulk CNS disease allowed except: Investigational agents. Agents that penetrate the CNS (e.g., high-dose methotrexate, thiotepa, high-dose cytarabine, fluorouracil, intravenous mercaptopurine).

Agents known to have serious unpredictable CNS side effects.

Endocrine Therapy: Not specified.

Radiotherapy: Recovery from toxic effects of prior radiotherapy required. Patient eligible if flow restored following focal radiotherapy to the blockage site.

Surgery: Not specified.

PATIENT CHARACTERISTICS:

Performance status: ECOG 0-2.

Life expectancy: At least 8 weeks.

Hematopoietic: See Disease Characteristics.

Hepatic: Bilirubin less than 2.0 mg/dL, SGPT less than 3 times normal.

Renal: Creatinine less than 1.5 mg/dL.

Metabolic: Serum electrolytes (including calcium and phosphate) normal.

Other: No significant systemic illness (e.g., infection). Not pregnant or lactating.
