Abstract
19 patients with advanced cancer were entered into a phase I study of recombinant human interleukin-4 (rhu IL-4). The predominant clinical side-effects included flu-like symptoms, gastrointestinal upset, lethargy and transient hypotension. In addition, there were several cases of capillary leak syndrome. 2 cases of gastrointestinal haemorrhage occurred; this was life threatening in 1 patient. The maximum tolerated dose (MTD) was 400 micrograms/m2/day. Biochemical toxicity was limited to asymptomatic elevation of liver enzymes suggesting IL-4 induced liver damage. Pharmacokinetic analysis following the intravenous bolus injection has shown that IL-4 is rapidly cleared (mean T1/2 = 19 +/- 8.7 min) from a small compartment (mean Vd = 4.9 +/- 3.68 l) probably indicating that IL-4 is retained in the systemic circulation or at most the extracellular fluid volume. 2 patients with non-Hodgkin lymphomas (NHL) showed a transient response to IL-4 whilst a third patient with NHL showed transient disease progression.
