Brief Summary:
Phase I trial to study the effectiveness of bryostatin 1 plus vincristine in treating patients who have recurrent or refractory lymphoma. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Bryostatin 1 may help vincristine kill more cancer cells by making them more sensitive to the drug

Condition or disease Intervention/treatment Phase
AIDS-related Diffuse Large Cell Lymphoma AIDS-related Diffuse Mixed Cell Lymphoma AIDS-related Peripheral/Systemic Lymphoma AIDS-related Small Noncleaved Cell Lymphoma Drug: bryostatin 1 Drug: vincristine sulfate Phase 1

Detailed Description:


I. Determine the maximum tolerated dose of bryostatin 1 when administered with vincristine in patients with recurrent or refractory HIV-related B-cell lymphoma.

II. Determine the toxicity profile of this regimen in these patients. III. Determine the objective response and survival of these patients treated with this regimen.

IV. Determine the immunomodulatory effects of this regimen on interleukin-2 (IL-2), IL-2 receptor, and IL-6 cytokine levels in these patients.

V. Determine the effect of this regimen on CD4+ lymphocyte count and HIV load in these patients.

VI. Determine the effect of this regimen on the human herpes virus-8 load in these patients with body cavity-based lymphoma.

OUTLINE: This is a multicenter, dose-escalation study of bryostatin 1.

Patients receive bryostatin 1 IV continuously on days 1 and 15 and vincristine IV over 5 minutes on days 2 and 16. Treatment continues every 4 weeks for a minimum of 2 courses in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of bryostatin 1 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.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 12 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase I Trial of Combination Bryostatin-1 and Vincristine in HIV-Related B-cell Neoplasms

Arm Intervention/treatment
Experimental: Treatment (bryostatin 1, vincristine sulfate)

Primary Outcome Measures :
  1. MTD of bryostatin-1 defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity [ Time Frame: 4 weeks ]

Secondary Outcome Measures :
  1. Dose-limiting toxicities [ Time Frame: 4 weeks ]
    Defined as any >= grade 2 neuropathy, other grade 3 non-hematologic toxicity (excluding alopecia and grade 3 nausea and vomiting that is responsive to standard pharmacologic intervention) or grade 4 hematologic toxicity in 2 or more patients. The incidence of toxicity related dose reduction and treatment discontinuation will be summarized for each dose group.

  2. Immunomodulatory effects of this combination [ Time Frame: Up to 2 years ]
    Measured by a solid phase Enzyme Amplified Sensitivity Immunoassay.
