Melanoma Clinical Trial

Evaluation of M40403 for the Prevention of Dose Limiting Toxicities of High Dose IL-2

Summary

The clinical use of IL-2 is currently limited by development of dose-dependent hypotension (systolic blood pressure (SBP) < 90 mm Hg). The overall outcome is constant across sites with 20-50% of the patients requiring ICU management because of unresponsive hypotension and hyporeactivity (loss of response to vasoconstrictors). Because of the dose-limiting side effects, the duration of IL-2 dosing is frequently curtailed. Thus, hemodynamic toxicities have limited the usefulness of IL-2 therapy. M40403 has prevented both the hypotension and hyporeactivity associated with IL-2 treatment in preclinical studies. This trial will study the safety and efficacy of M40403 in the prevention or reduction of hypotension in patients receiving IL-2 therapy.

Full Description

High-dose interleukin-2 (IL-2) therapy is currently indicated for treatment of metastatic renal cell carcinoma and metastatic malignant melanoma, and has been associated with a 5-15% long-term clinical response. In addition, IL-2 therapy is showing promise in treatment of acute myelogenous leukemia, non-Hodgkin's lymphoma, and breast cancer, and in improving immunologic function in patients with AIDS. However, the major dose-limiting toxicity of IL-2, hypotension, severely limits the usefulness of IL-2 therapy.

Because of the unresponsive hypotension and loss of response to exogenously administered vasopressors, 20-50% of the patients receiving high dose IL-2 therapy require ICU management. These dose-limiting side effects frequently necessitate curtailing the full period of IL-2 dosing in order to reverse the hypotension and prevent subsequent renal dysfunction. Thus, hemodynamic toxicities have limited the usefulness of IL-2 therapy. A course of IL-2 therapy requires long hospitalization and intense patient monitoring during administration. As a consequence, despite favorable long-term response, few sites offer this treatment.

The availability of an agent that prevents IL-2-induced hypotension without adversely affecting the therapeutic mechanism of IL-2, would markedly facilitate IL-2 administration and at a minimum, would maximize the number of patients who could receive the full regimen of IL-2. The reduction in IL-2 toxicity may also enable higher doses and/or more frequent dosing of IL-2 to be used, with the potential of higher success of tumor response. Because M40403 may decrease the toxicity of IL-2, co-administration of M40403 may make it possible to broaden the clinical use of IL-2 to conditions where it is not currently indicated.

The indication to be studied is for use in the prevention or reduction of hypotension associated with interleukin-2 (IL-2) therapy in patients with metastatic melanoma and renal cell carcinoma.

The study is divided into a sequential dose escalation phase followed by the expansion of the selected dose in a double-blind, placebo-controlled, evaluation phase. Patients with metastatic or inoperable melanoma and renal cell carcinoma will be receiving high dose IL-2 per approved labeling as two 5-day sequences. M40403 will be administered by intravenous infusion over 30 minutes prior to each intravenous administration of high dose IL-2. Sequential panels of patients will receive increasing doses of M40403 along with IL-2 until an active dose is determined and an MTD is reached. Patients will be followed to determine the effects of M40403 on development of markers of IL-2 dose-limiting toxicity including hypotension, tachycardia, index of renal perfusion, cumulative dose of pressor required and cumulative dose of IL-2 administered. Approximately 48 patients will be studied.

Patient has received radiotherapy, chemotherapy, or immunotherapy in the four weeks prior to the first dose of study drug, or is scheduled to receive concurrent radiotherapy, chemotherapy, or immunotherapy.
Patient has contraindication to treatment with pressor agents.
Patient currently receives chronic medication for asthma.
Patient has a history of another malignancy other than basal cell skin cancer within 5 years prior to the first dose of study drug.
Patient has any significant medical disease other than the malignancy which, in the opinion of the investigator, may interfere with completion of the study.
Patient has previously received any IL-2 therapy.
Patient has received another investigational medication within 4 weeks prior to M40403 administration or is scheduled to receive an investigational drug other than M40403 during the course of the study.
