Amonafide, a benzisoquinoline-1,3-dione with anti-tumor activity in preclinical screens, was administered to patients with recurrent or metastatic bidimensionally measurable colorectal cancer. Fourteen patients with no prior chemotherapy for advanced disease, performance status 0-1, and normal bone marrow, renal, and hepatic function were entered. Amonafide 300 mg/m2 was administered intravenously over 1 hour daily for five consecutive days; courses were repeated every three weeks. The major side effect was neutropenia: Grade 3 or 4 toxicity occurred in 5/14 patients. Other toxicities included nausea and vomiting, flulike symptoms, fever, rash and alopecia. Three patients had stable disease, but there were no responses observed. Amonafide at this dose and schedule has no activity in the treatment of colorectal cancer.

Amonafide is a new synthetic anticancer agent whose mechanism of action is through inhibition of macromolecular synthesis as well as DNA intercalation. The Southwest Oncology Group (SWOG) has investigated this drug in a phase II study of pancreas cancer. Thirty-six patients were registered on this study: of these 29 were eligible for response evaluation, and 20 received the two cycles required for making a response assessment. Patients met the standard phase II criteria of no prior chemotherapy, measurable disease and a SWOG performance status of 2 or less. Toxicity, predominantly hematologic with significant neutropenia and thrombocytopenia, was quite severe. Four treatment related deaths were encountered. No responses were seen in thirty-six patients studied. We conclude that this drug is not active against adenocarcinoma of the pancreas.

Amonafide (nafidimide), a synthetic organic compound with an inhibitory effect on cellular replication, was used in a phase II study conducted by the Illinois Cancer Center in order to assess its efficacy and toxicity in advanced or recurrent squamous cell cancer of the head and neck. Eligible patients had received no more than one prior adjuvant or neoadjuvant chemotherapy, had normal bone marrow, renal and hepatic function, ECOG performance status of 0-2, and bidimensionally measurable disease. Eligible patients were administered amonafide at a starting dose of 300 mg/m2 for five consecutive days every 3 weeks with dose escalation or de-escalation according to established hematologic criteria in the absence of disease progression. Nineteen of 22 entered patients were evaluable for response and all patients were evaluable for toxicity. Eleven of 19 patients achieved stable disease. Median time to progression after start of treatment was 57 days, for the 18 patients for whom the date of progression is known. There were no partial or complete responses. Hematologic toxicity was dose limiting with grade 3-4 neutropenia in 50 percent of patients and 4 deaths associated with neutropenic sepsis. Non-hematologic toxicity was mild to moderate with nausea and vomiting predominating. In this study, amonafide was a myelotoxic, inactive treatment in advanced/recurrent head and neck cancer. Further use in head and neck cancer appears unwarranted.
