The hypoxic cell sensitizer misonidazole began phase I evaluation in the United States in July 1977. One hundred two patients received 104 individual courses of drug. Drug was administered from once to five times per week over time spans from one to six weeks. The individual doses ranged 1 to 5 g/m. The major toxicity noted was neurologic; 49% of evaluable courses showed peripheral neuropathy, and 9% of evaluable courses showed central nervous system effects and/or ototoxicity. In addition, 48 of 102 patients exhibited some degree of nausea and vomiting. The concomitant administration of dexamethasone and phenytoin sodium appeared to lower the incidence of neuropathy. Observations of efficacy were made comparatively in five patients who had multiple lesions treated with and without misonidazole. All five showed increased response in the lesions treated with misonidazole. It is concluded that misonidazole is a reasonably safe and potentially effective hypoxic cell sensitizer whose dose-limiting toxicity is neurologic.
