Complex-binding of anthracyclines to DNA may increase their therapeutic efficacy. In a previous randomized trial patients with acute myelocytic leukaemia (AML) receiving combination chemotherapy including a DNA-bound doxorubicin preparation had a longer duration of first complete remission (CR) and survival than patients receiving free doxorubicin. In a parallel phase I/II study a combination of mitoxantrone, activity. In this randomized study of AML patients (15-60 years) induction treatment with MEA was compared to a combination of doxorubicin/DNA conjugate ara-C, thioguanine, vincristine and prednisolone (POCAL-DNA). The study was closed after an interim analysis of 86 patients. Thirty-five/42 (83%) and 20/44 (45%) patients entered CR in the MEA and POCAL-DNA groups, respectively (p < 0.001). With rescue therapy the corresponding figures were 88 and 64% (p < 0.02). Median survival was 27.8 and 13.1 months for MEA and POCAL-DNA patients, respectively (p < 0.03). In conclusion, the MEA regimen has a very high antileukaemic activity in good accordance with our previous experience. Since we could not reproduce our earlier clinical results using DNA-bound anthracyclines, the source and preparation of DNA seem to be of major importance.
