In an attempt to prolong disease-free survival in children with acute leukemia, we tested the feasibility of interleukin-2 (IL-2) administration after an autologous bone marrow transplantation (ABMT). We report the clinical and biological data obtained in three children with acute myelocytic leukemia (AML) in second complete remission (CR) and in seven children with acute lymphocytic leukemia (ALL) in second or subsequent CR, who received IL-2 at a median interval of 78 days (range 38-125) from ABMT. Patients were treated with 1-2 cycles of IL-2 given by continuous infusion over a 5-day period using a daily escalating protocol, from 100 micrograms/m2 per day to the maximum tolerated dose, followed after 3 weeks by low-dose IL-2 for 5 days monthly over a 6-h infusion on an out-patient basis. Side effects greater than grade 2 (WHO system), consisting of thrombocytopenia, fever, cutaneous rash, nausea and vomiting, diarrhoea were common during the high-dose IL-2 cycles, but resolved 24-48 h after stopping IL-2. Only one patient developed liver toxicity (grade 3, WHO) on day +3 of the first cycle which prompted us to stop the administration of IL-2. An increase in lymphocytes and eosinophils was also observed. IL-2 treatment was followed by a normalization of NK function and by the generation of a high proportion of endogenous LAK cells. All seven ALL patients relapsed at a median of 5 months (range 1-23). Two AML patients relapsed at 1 and 11 months, while the other is still in continuous CR at 23 months after IL-2 treatment. Our IL-2 schedule for treatment of leukemia in children after ABMT is thus feasible but its efficacy requires further investigation.

Recurrent or induction therapy-resistant ANLL carries a grave prognosis. The combination of AMSA at 100 mg/M2 daily for 5 days and etoposide at 200 mg/M2 daily for the first 3 days of therapy was given to 40 patients with refractory ANLL. An additional 17 patients received those two agents plus azacitidine at a dosage of 250 mg/M2 on days 4 and 5. All three drugs were given as one-hour infusions. All patients had normal electrolyte determinations daily and were on cardiac monitors during the period of drug administration. No arrhythmias were detected in 522 doses of AMSA. Toxicities observed were primarily related to myelosuppression. Forty-nine of the 57 patients required hospitalization for suspected or proven infection. Nausea/vomiting and mucositis were the next most commonly occurring toxicities. Responses were seen in 22 patients.

Carboplatin (CBDCA) is a second-generation platinum drug that has been shown to be useful when used as a continuous infusion in treatment of refractory adult leukemia. We report on the effectiveness of continuous infusion CBDCA, 300 mg/m2/d x 5 days, as evaluated in nine patients with secondary acute nonlymphocytic leukemia (ANLL) (seven previous myelodysplastic syndrome and two treatment-associated ANLL), three ANLL patients in first relapse, six refractory ANLL, and nine patients with blastic phase of chronic myelogenous leukemia (BP-CML). All patients were considered assessable. The response rate was 44% (eight complete remissions [CRs], four partial remissions [PRs]). Median duration of postchemotherapy neutropenia was 36 days (range, 18 to 45). Therapy was well tolerated, and toxicity was mainly hematologic and nondose-limiting. Despite prolonged neutropenia, severe infections were rarely seen, and most patients were managed as outpatients. Twelve patients had nausea and vomiting, two had symptomatic hypomagnesemia, and one patient showed reversible ototoxicity. Because of substantial antileukemic activity and unusual extrahematologic toxicity, CBDCA appears to be an effective second-line agent in the treatment of ANLL and should be considered for upgrading to first-line treatment regimens.

Mitoxantrone in combination with VP-16 proved to be effective in refractory and relapsed acute myeloid leukemia (AML), with 42% of patients achieving complete remission (CR). The aim of this study was to assess whether the addition of cytosine arabinoside increased the response rate at a tolerable toxicity. The regimen consisted of mitoxantrone (M) 10 mg/m2 i.v. days 4-8, cytosine arabinoside (A) 100 mg/m2 continuous infusion days 1-8, and etoposide (VP-16) (V) 100-120 mg/m2 i.v. days 4-8 (MAV protocol) for relapsed and refractory AML. Thirty-six patients were treated, with a median age of 51 (20-73) years. For induction therapy one to two MAV cycles and for consolidation therapy two courses were scheduled. Twenty-one (58.3%) patients attained a complete remission (CR), with a median duration of 4.5 (1-12+) months. The median survival of all patients was 5.5 (0.5-15.5+) months. Four patients died in CR from chronic infections or after consolidation therapy with MAV. In evaluable patients, times to greater than 500 granulocytes/microliters and greater than 25,000 platelets/microliters were 23 (7-46) and 23 (6-44) days, respectively. In 54 evaluable MAV courses the following toxicity was observed (WHO grades 3/4): 26%, nausea and vomiting: 9%, hemorrhage; 6%, bilirubinemia; 11%, diarrhea; 22%, mucositis; 6%, local infection; 20%, septicemia; 13%, fever of unknown origin; 2%, cardiac arrhythmia; 7%, congestive heart failure. We conclude that MAV therapy is a highly active antileukemic combination with acceptable toxicity, which is recommended for further clinical trials in untreated AML.

Idarubicin is a new derivative of Daunorubicin which was found to be more potent and more active than Daunorubicin and Doxorubicin in several experimental leukemias. Its antileukemic activity in preclinical models prompted the introduction of Idarubicin into clinical studies. As a single agent, Idarubicin produced complete remission in 20% and 30% of patients with heavily pretreated pediatric and adult acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) respectively. Idarubicin combined with Cytarabine and/or other antileukemic agents produced complete remissions in 46% of patients with refractory or relapsed AML and in 58% of patients with refractory or relapsed ALL (adult and pediatric). Subsequently, Idarubicin has been employed in untreated AML patients in combination with Cytarabine and/or Etoposide, producing complete remissions in more than 80% of patients. In ALL patients the drug has been used in combination with Vincristine, Cytarabine and Prednisone, producing complete remissions in 82% of patients. Recently, Idarubicin has been utilized in combination with intermediate doses of Cytarabine in refractory or relapsed ALL and AML, and 70% of patients achieved complete remission. Preliminary results of ongoing prospective randomized studies in untreated adult AML seem indicate that Idarubicin is at least equivalent, if not superior to Daunorubicin. The antileukemic activity of Idarubicin given orally as single agent, or in combination with other drugs, has been shown in AML and myelodysplastic syndromes. The toxicity of Idarubicin includes mild nausea and vomiting, alopecia and liver dysfunction. Ongoing randomized trials comparing Idarubicin to Daunorubicin should provide more information about the potential cardiotoxicity of this drug.

Based on in vitro evidence of time-dependent synergistic kill of HL-60 leukemia cells exposed to Ara-C and mitoxantrone, 44 patients with relapsed or refractory AML and 3 with blastic CML were treated with a timed sequence of both drugs. There were 25 females and 22 males, with a median age of 53 (range 21-75). Of 31 patients with relapsed AML, 24 had one prior remission, 6 had two and 1 had three. Of these, 15 had failed a second reinduction attempt. Thirteen patients were primarily refractory to induction with Ara-C plus daunorubicin. Each dose of Ara-C, 500 mg/m2, was followed after 6 hr by mitoxantrone, 5 mg/m2, and the sequence was repeated four to six times (44-68 hr) in different cohorts of patients. All but two patients (one with blastic CML and one in relapse and refractory) are evaluable for response and toxicity. Of 16 patients in relapse without prior reinduction 7 achieved CR and 3 PR (62% response rate); there were 3 CR in the 14 patients who were in relapse and refractory (21% response rate) and 4 CR and 1 PR (35% response rate) in the 14 patients with primary anthracycline resistance. Five of seven patients previously exposed to mitoxantrone achieved CR. Response lasted from 2 to 42 months, with two patients alive and in continuing remission at 34 and 42 months. Average marrow recovery was seen after 25 days and time to remission was 30 days. Six patients died in induction (four from sepsis and two from the tumor lysis syndrome) and 21 had progressive disease. Chemotherapy was well tolerated with minor nausea and vomiting in 13 patients, moderate in 20, and severe in 2. Most patients did not have evidence of drug-induced mucositis: it was minor in 9 and moderate in 2. Renal dysfunction was attributable to the use of nephrotoxic antibiotics. Hepatic dysfunction was reversible and was minor in 10 patients, moderate in 13, and severe in 3. Sequential, timed administration of intermediate-dose Ara-C and mitoxantrone is an active and well-tolerated antileukemic regimen.

DWA2114R (DWA) is a new derivative of platin compounds that is currently being used in Phase II studies of solid tumors in Japan. The dose-limiting factor is myelotoxicity with mild extramedullary toxicity. This Phase I study consisted of adult patients with relapsed hematologic malignancies. Eight patients received a total of 15 treatment courses of DWA. The starting dose was 800 mg/m2 over 24 hours by continuous infusion. The dose was first increased to 1200 mg/m2 and then to 1600 mg/m2. Clinical toxicity and urinary excretion studies of DWA suggested that 1200 mg/m2/d for successive days would be the best type of administration. When 1200 mg/m2/d was given for 5 days, Grade 2 to 3 diarrhea and nausea and vomiting were encountered requiring parenteral fluids and nutritional support. This suggested that the dose-limiting factor with this schedule was gastrointestinal toxicity. Myelotoxicity was severe, as expected, but tolerable. One of the five patients with acute nonlymphocytic leukemia (ANLL) entered into complete remission and one patient with chronic myelogenous leukemia (CML) in crisis returned to the chronic phase. A Phase II trial of DWA is warranted for hematologic malignancies, especially in myeloid diseases.

In an effort to search for new, synergistic and non-cross-resistant antileukemic regimens, the Cancer and Leukemia Group B (CALGB) investigated the activity and toxicity of mitoxantrone in combination with etoposide for the reinduction of patients with relapsed or refractory acute myelocytic leukemia (AML). Mitoxantrone, 12 mg/m2 daily for 3 days, was combined with three dose levels of etoposide, 100, 150 and 200 mg/m2 daily by constant infusion for 5 days. There were 19 male and 13 female patients, with a median age of 46 (range, 21-74). Of these, nine were primarily refractory to daunorubicin and ara-C; 17 had one prior complete remission (CR), five had two prior CR, and one had three prior CR. Thirteen patients were entered at the first dose level, 11 were entered at the second, and eight at the third. All but one patient, whose death occurred within the first 2 days of treatment, are evaluable for toxicity. There were five CR (four at the first and one at the second dose level) and six partial remissions (PR) (three at the first dose level and three at the second). Unmaintained responses lasted 6-33 weeks. Median survival for all patients was 12.6 weeks. Anti-leukemic effects with severe marrow hypoplasia were observed in all patients; severe nausea and vomiting were seen in four. Severe mucositis, often indistinguishable from superimposed candidiasis, occurred in 40% of all patients; it was associated with dose-limiting esophagitis (three of seven evaluable patients) at the highest etoposide dose. Hepatic and renal dysfunction was severe in three patients; no treatment-related severe pulmonary or cardiac toxicity was observed. Posttreatment infectious complications were severe in 11 patients. In three cases, they were fatal--an incidence not dissimilar from that of other reinduction regimens in heavily pretreated patients. The regimen appears to be active; the combination of mitoxantrone, 12 mg/m2 daily for 3 days, with etoposide, 150 mg/m2/day for 5 days, by constant intravenous infusion is now being explored by the CALGB in a randomized phase II study against mitoxantrone plus diazoquinone and diazoquinone plus etoposide.

Two groups of AML patients (n1 = 63, n2 = 20) and two groups of ALL patients (n1 = 33, n2 = 15) were treated using polychemotherapy protocols which in each leukaemia subtype differed mainly in adriblastin administration being either in bolus form (30 mg/m2/day i.v.) or fractional form at the beginning 20 mg i.v., then 6 mg/m2 every 6 h. The fractional method of administration was elaborated on experimental data indicating the superiority of continuous infusion of anthracyclines. In AML additional ara-C was given in continuous infusion only on 1 to 3 days, on 4 to 8 days duplicated dose was administered subcutaneously (i.e. 100 mg/m2 every 12 h). In patients given fractional doses of adriblastin and in AML also ara-C in the modified way the statistical analysis revealed a higher CR (ALL - 67%/93%, AML - 46%/60%) and CR + PR rates, a lower rate of infections as the cause of death in the AML group, lower rates of nausea and vomiting as well a lower increase of infections in the course of the induction treatment in the AML group. Another advantage was a lower total dose of adriblastin for remission induction treatment as well as an elevated cumulative dose which allows anthracyclines to be longer used. The efficacy of the modified ara-C administration confirms our earlier observation.

13 patients with refractory or relapsed acute lymphoblastic leukemia (ALL) and 7 patients with acute myeloid leukemia (AML) were treated with a regimen that included idarubicin 12 mg/m2 intravenously daily for 3 d plus cytarabine 2 g/m2 by infusion over 3 hours daily for 3 d. There were 10 remissions (ALL:7; AML:3) in the 15 relapsed patients and 4 (ALL:3) in the 5 patients with primary refractory disease. Severe myelosuppression was observed in all patients. Toxicity of this regimen caused nausea and vomiting, stomatitis, infections and/or liver enzymes increase. Cardiac toxicity was not observed. 2 patients died in aplasia of Gram-negative septicemia and brain hemorrhage. In conclusion, the combination of idarubicin and intermediate-dose cytarabine (IDARA-C) seems to be highly effective and sufficiently well-tolerated for the treatment of refractory and relapsed acute leukemias.
