Investigation of Safety, Tolerability and Maximum Tolerated Dose (MTD) of BI 2536 in Patients With Recurrent Advanced Aggressive Non-Hodgkin's Lymphoma (NHL)

OBJECTIVES:

Primary

• Determine the maximum tolerated dose of BI 2536 in patients with refractory or relapsed advanced aggressive non-Hodgkin's lymphoma.
• Determine the safety and tolerability of this drug in these patients.

Secondary

• Determine the pharmacokinetic profile of this drug in these patients.
• Determine, preliminarily, the antitumor activity of this drug in these patients.

OUTLINE: This is a dose-escalation, open-label, uncontrolled, multicenter study.

Patients receive BI 2536 IV over 1 hour on day 1. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of BI 2536 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity during the first treatment course. Up to 24 patients are treated at the MTD.

After completion of study treatment, patients are followed periodically until disease progression or initiation of another cancer treatment.

PROJECTED ACCRUAL: A maximum of 50 patients will be accrued for this study.

PRIOR CONCURRENT THERAPY:

Biologic therapy

• See Disease Characteristics
• See Radiotherapy
• More than 3 weeks since prior and no concurrent immunotherapy
• No prior allogeneic bone marrow transplantation

Chemotherapy

• See Disease Characteristics
• More than 3 weeks since prior and no concurrent chemotherapy (6 weeks for nitrosoureas or mitomycin)

Endocrine therapy

• More than 8 weeks since prior and no concurrent systemic radioimmunotherapy
• More than 3 weeks since prior and no concurrent radiotherapy

• Concurrent palliative radiotherapy to sites other than the only measurable target lesion allowed for symptom control provided the reason for radiotherapy does not reflect progressive disease

Other
