4'-Deoxydoxorubicin (dxDx), a new doxorubicin analogue, was administered intravenously on a 3-week schedule to 73 patients affected by advanced malignant neoplasms. Sixty-five patients, treated with eight dose levels ranging from 10 to 45 mg/m2, were evaluable. The dose-limiting toxicity was myelosuppression, mainly leukopenia. About one third of the patients complained of vomiting which was almost always mild. Minimal hair loss was also documented in about 40% of patients. No hepatic or renal toxicity was observed. Transient and aspecific electrocardiographic changes were recorded in 6% of patients after 1 h and in 3% after 24 h from drug injection. Left ventricular ejection fraction was decreased in two patients after a cumulative dose of 90 mg/m2. One patient died with cardiorespiratory insufficiency and his initial cardiovascular disease might have been aggravated by dxDx. No changes in myocardial function parameters were documented in 18 patients who reached higher cumulative doses, i.e. greater than or equal to 100 mg/m2 and greater than or equal to 200 mg/m2. The highest total dose administered in this study was 340 mg/m2. Therapeutic activity was observed with doses ranging from 25 to 45 mg/m2. Partial response was documented in pancreatic, colon, anal and breast carcinomas as well as in non-Hodgkin's lymphoma. Minor response was observed in prostatic, thyroid, and renal carcinomas as well as in chronic lymphocytic leukemia. The maximum tolerated dose was assessed to be between 40 and 45 mg/m2. A Phase II trial is ongoing utilizing the dose of 35 mg/m2 every 3 weeks.

Phase I trial with 4′-deoxydoxorubicin (esorubicin)

4'-Deoxydoxorubicin is a new anthracycline derivative. Experimentally, the drug shows efficacy against doxorubicin-resistant malignancies and, as compared to the parent compound, it has reduced potential for heart damage. This Phase I trial was conducted with a single dose intermittent schedule. 4'-Deoxydoxorubicin was given by rapid i.v. administration at doses of 20, 30, 35 and 40 mg/m2. A total of 25 adult patients with a variety of solid tumors received a median of two courses (1-4). Leukopenia was dose-related and dose-limiting. Occasionally severe thrombocytopenia was also encountered. Nonhematological toxic effects were mostly mild to moderate and were qualitatively similar to those commonly reported with doxorubicin. The frequency of local reactions was apparently increased but the incidence of alopecia and gastrointestinal distress was noticeably lower. There were no acute or chronic drug-induced cardiac effects. Antitumor activity was suggested in a patient with a carcinoma of the cardia. For Phase II trials, doses of 35 and 30 mg/m2 every 3-4 weeks may be recommended in good-risk and poor-risk patients, respectively.

Anthracycline antibiotics remain among the most potent anticancer drugs, but their efficacy is limited by the development of a dose-dependent irreversible cardiomyopathy and by the emergence of clones of tumor cells resistant to the effects of the drug. Modifications of the basic anthracycline structure have resulted in molecules that may share the activity of the parent compound, with amelioration of some toxicities, absence of cross-resistance, or activity against tumors insensitive to the parent drug. Epirubicin has a unique metabolic pathway, glucuronidation, that may result in more rapid plasma clearance and reduced toxicity as compared with doxorubicin. Epirubicin has demonstrated comparable activity to doxorubicin in breast cancer, with possibly reduced toxicity. Idarubicin is of interest because of its cytotoxic activity when given orally. Idarubicin has prolonged retention in the plasma and has equal cytotoxic activity to the parent compound. Idarubicin has demonstrated activity against acute leukemia and breast cancer; in the latter tumor category, some doxorubicin-resistant tumors have responded. Esorubicin is of interest because of its nearly absent cardiac toxicity. This agent has some activity against solid tumors and is currently being clinically tested. Aclacinomycin A is an anthracycline in which a trisaccharide is substituted for the aminosugar. Aclacinomycin A and the related compound marcellomycin are of interest as both cytotoxic and differentiating agents. Menogaril is an anthracycline with the aminosugar on the D ring; it does not exhibit cross-resistance with doxorubicin or cardiotoxicity. Mitoxantrone is a compound that is related to the anthracyclines but has a different mechanism of action. This agent has significant activity against acute leukemia and breast cancer and is currently being compared with doxorubicin. Amsacrine is another compound related to the anthracyclines that possesses major activity against acute leukemias. Minor modifications of the anthracycline molecule have had major impact on the biologic activity of these drugs. New anthracycline analogues with up to 100 times the potency of currently available anthracyclines are being developed for clinical testing, and these complex molecules retain a nearly unlimited potential for structural modification.
