Phase I Study of Interleukin-12 in Combination With Rituximab in Patients With Non-Hodgkin's Lymphoma
OBJECTIVES: I. Determine the optimal immunological dose of interleukin-12 and rituximab when
administered in combination in patients with non-Hodgkin's lymphoma. II. Determine the
toxicities associated with this regimen in this patient population. III. Assess the
pharmacodynamics of this regimen in these patients. IV. Document observed clinical response
to this regimen in these patients.
OUTLINE: This is a dose escalation study of interleukin-12. Patients receive rituximab IV on
days 1, 8, 15, and 22. The first cohort of patients receives interleukin-12 SC twice weekly
beginning on day 29. Subsequent cohorts receive interleukin-12 SC twice weekly beginning on
day 16. Patients with stable or responding disease may continue treatment with
interleukin-12 twice weekly for up to 24 weeks or until disease progression. Cohorts of 6-9
patients receive escalating doses of interleukin-12 until the optimal immunological dose is
determined. The optimal immunological dose is defined as the dose preceding that at which 2
of 6 or 2 of 9 patients experience dose limiting toxicities or the dose at which there is a
maximal increase in gamma interferon, inducible protein-10 (IP-10) and immune cell
infiltration into the lymphoma (whichever dose is lower). Following initial dose escalation,
2 additional cohorts of 6 patients receive a fixed dose of interleukin-12 SC twice weekly
beginning on day 2. Patients are followed every 3 months for the first year, and then every
6 months for the next 4 years or until disease progression.
PROJECTED ACCRUAL: A maximum of 45 patients will be accrued for this study within 12-13
months.
