A phase I trial of diglycoaldehyde (Inox) in children with leukemia established that the maximum tolerated dose of a 5-day schedule was 1.5 g/m2/day. A phase II study was undertaken by the Children's Cancer Study Group to evaluate the efficacy of this dose. Forty-seven children with acute leukemia refractory to conventional forms of therapy were entered in the study: 29 patients with acute lymphocyte leukemia/acute undifferentiated leukemia and 18 with acute nonlymphocytic leukemia. Inox was administered at a dose of 1.5 g/m2 as a 4-6 hour iv infusion daily for 5 days every 14 days. Toxic effects included myelosuppression, proteinuria, nausea, vomiting, diarrhea, local tissue reactions, hypocalcemia, transitory serum amylase elevation, and transitory hypotension. There was one life-threatening episode of drug-related renal toxicity. Of the 27 patients who received a minimum of two courses, partial remissions were observed in two patients with acute nonlymphocytic leukemia. Inox was inactive against advanced acute lymphocytic leukemia.

Succinylated Acinetobacter glutaminase-asparaginase (SAGA) has broader antitumor activity than Escherichia coli L-asparaginase in experimental systems; moreover, drug resistance does not develop in tumor cell lines initially sensitive to this enzyme. We have investigated the pharmacology and toxicology of SAGA after both single-dose and serial daily dose injections in 20 adult patients. Glutaminase activity in plasma after i.v. injection of single doses did not follow simple first-order kinetics (half-life during the initial 24 hr was 21 +/- 9 hr. A linear relation was observed between increasing doses of SAGA and resultant levels of plasma enzyme activity and blood glutamate. Assay of whole blood which had been deproteinized immediately following phlebotomy showed that single doses of SAGA lowered glutamine only transiently to nondetectable levels; serial daily doses were required to achieve and maintain continuous glutamine depletion. Reversible depression of the central nervous system, ranging from encephalopathy to coma, occurred in a dose-related manner and was dose limiting. Other prominent reactions included respiratory alkalosis, hyperglycemia, nausea, and vomiting. Transient antitumor effects were noted in two patients with solid tumors and in two patients with leukemia. SAGA causes considerable neurotoxicity in adults which requires close patient monitoring. Phase II studies in leukemic patients are in progress.

The serotonin (5HT3) antagonist ondansetron was compared in a randomised study with metoclopramide and dexamethasone for the prevention of chemotherapy induced emesis. Thirty children aged 1-15 years with acute lymphoblastic leukaemia received 'intensification modules' according to the MRC United Kingdom acute lymphoblastic leukaemia regimen UKALL XI. This contains the moderately emetogenic drugs daunorubicin, etoposide, and cytarabine. Fifteen children received an intravenous loading dose of ondansetron followed by intravenous or oral doses 12 hourly for five days. Fifteen children received intravenous metoclopramide every six hours for three days with a loading dose of dexamethasone, repeated every eight hours for three days intravenously or orally. Efficacy was assessed by a diary card documenting the incidence of nausea, retching, or vomiting. In the 24 hour period after starting chemotherapy, ondansetron was more effective, with a complete or major response rate of 93%, compared with 33% using metoclopramide/dexamethasone.

The camptothecin analogues topotecan and irinotecan (CPT-11) are active anticancer drugs. This article reviews the accumulated results of clinical and laboratory studies performed with these agents at The Johns Hopkins Oncology Center. In a phase I clinical and pharmacology trial of topotecan given as a 30-min infusion daily for 5 days every 3 weeks, profound neutropenia precluded dose escalation above 1.5-2.0 mg/m2 per day, the maximum tolerated dose (MTD). The daily x5 schedule has been developed further with dose escalation using granulocyte-colony-stimulating factor support in patients who have kidney or liver dysfunction and given in combination with cisplatin. In addition, a phase I trial of topotecan given as a 5-day continuous intravenous infusion to patients with refractory leukemia has had promising antileukemic responses. A separate series of in vitro studies indicates that a modest degree of resistance to the cytotoxicity of topotecan can be mediated by P-glycoprotein. A phase I and pharmacology study of irinotecan given as a 90-min infusion every 3 weeks has defined an MTD of 240 mg/m2, with dose escalation being limited by several toxicities. These included an acute treatment-related syndrome of flushing, warmth, nausea, vomiting, and diarrhea; a subacute combination of nausea, diarrhea, anorexia, and weight loss; and/or neutropenia. Antitumor activity has been observed with topotecan and irinotecan in patients with a variety of solid tumors and refractory leukemia in our studies, which supports the widespread enthusiasm for this group of compounds.

Zygomycosis is an uncommon, but frequently fatal, fungal infection caused by members of the class Zygomycetes. The risk factors include diabetes mellitus, uremia, leukemia and use of deferoxamine as an iron-chelating agent; healthy persons also are occasionally infected. Those fungi, spread by their ubiquitous spores, most frequently involve the respiratory system. Rhinocerebral zygomycosis occurs predominantly in patients with uncontrolled diabetic ketoacidosis. Pulmonary zygomycosis most frequently is observed in granulocytopenic and corticosteroid-treated patients. Other clinical manifestations are gastrointestinal, cutaneous, disseminated and miscellaneous. This report concerns a previously robust farmer who suffered from left upper lung abscess caused by Rhizopus spp.-one member of the order Mucorales. Initially, it was intended to administer amphotericin B to a total dose of 2,000 mg; however, the patient could not tolerate such side effects as nausea, vomiting and refused further management when the cumulative dose was 948 mg. However, he did recover without further fever and cough. Chest X-ray, followed every three months, disclosed satisfactory improvement.

One hundred sixteen cases of leukemia patients received supra-high single dose TBI for bone marrow transplantation (BMT) with total a radiation dosage of 700-770 Gy at about 5cGy/min. Seventy patients were given ondanstron (8mg) plus dexamethasone (DXM, 10mg) for prophylaxis of TBI-induced acute nausea and vomiting, 46 patients were given paspertin (10mg) plus dexamethasone (10mg) as controls. The clinical results showed that ondansetron plus DXM achieved complete or major control of vomiting in 59/70 (84%) of cases and there was little or no nausea in 61/70 (87%), while paspertin plus DXM achieved complete or major control of vomiting only in 9/46 (20%) of cases and little or no nausea in 5/46 (11%). It is concluded that ondansetron has significantly greater advantage over paspertin in the control of acute emesis induced by TBI.

Twenty two patients with acute relapsed leukemia (AML 20, ALL 2) were treated with 5-aza-2'-deoxycytidine (DAC) and either m-amsacrine or idarubicin. DAC was administered as a 6-h infusion, every 12 h for 6 days in combination with either m-amsacrine (120 mg/m2) as a 1-h infusion on days 6 and 7 (n = 19) or idarubicin (12 mg/m2) as a 15-min infusion on days 5, 6 and 7 (n = 3). Thirteen patients (59%) achieved a complete remission. The treatment was complicated by nausea, vomiting, diarrhoea with signs of peritonitis (n = 9), weight loss (n = 7), cerebellar or cerebral toxicity (n = 2), gastrointestinal bleeding (n = 3), liver toxicity (n = 2) and prolonged myelosuppression. Median duration of remission was 4 months (range 1-30). The preliminary data show that DAC is an anti-leukemic agent, comparable to high dose Ara-C with comparable severe toxicity.

A phase I study of NKT-01 (deoxyspergualin), which is a derivative of an antitumor antibiotic, spergualin, was performed by a cooperative study group. NKT-01 was given intravenously by 3-h infusion. The effect of single administration was studied prior to evaluation of daily administration for 5 consecutive days. In all, 5 and 33 patients with various malignancies, including leukemia, were entered into the trials of single and daily administration, respectively. In the single-administration study, all patients were evaluable and no clear adverse effect was observed at doses ranging from 20 to 320 mg/m2. In the daily-administration study, 28 evaluable patients (16 men and 12 women; median age, 55.5 years) were treated with a daily dose of 20-500 mg/m2. Toxicities such as myelosuppression, mild nausea/vomiting, anorexia, alopecia, tongue and perioral numbness, and hypotension were observed dose-dependently during or after the treatment. Grade 2 leukopenia, thrombocytopenia, and anemia were experienced at a dose of 500 mg/m2. These usually recovered to normal values by approximately 3 weeks after treatment. A pharmacokinetic analysis of single administration revealed rapid plasma clearance, with mean half-lives for the alpha and beta phases being 28 min and 6.9 h, respectively. Approximately 12% of the infused dose was excreted into the urine in unmetabolized form. The pharmacokinetic parameters obtained after 5-day administration were similar to those recorded after single administration. Concerning treatment response, a transient but significant reduction in the number of leukemic cells was observed in one patient with adult T-cell leukemia. In this study, perioral numbness, hypotension, and hematological toxicity were concluded to be dose-limiting, with the maximal acceptable dose being 500 mg/m2. The recommended dose for a phase II study of NKT-01 against solid tumors was judged to be 400 mg/m2 given daily by 3-h infusion for 5 days, every 3 weeks. In hematological malignancies, however, higher myelosuppressive schedules of administration should be investigated.

A late phase II study of a new camptothecin analogue, irinotecan hydrochloride (CPT-11), was conducted to evaluate the anti-tumour effect and toxicity in patients with refractory leukaemia and lymphoma including adult T-cell leukaemia (ATL)-lymphoma, in a multi-institutional cooperative study. All the patients with ATL had been previously treated with various conventional combination chemotherapies and were refractory to these therapies or had relapsed. CPT-11 was administered at a dose of 40 mg m-2 day-1 for three consecutive days repeated weekly until evidence of disease progression. One complete remission and four partial remissions were achieved in 13 assessable patients with ATL. The median total dose to achieve remission was 240 mg m-2 and the median duration of response was 31 days. The major toxicities were leucopenia (83%), diarrhoea (62%) and nausea/vomiting (69%). These were relatively severe, but they were generally tolerable and reversible. However, one patient died probably as a result of this therapy. No effective chemotherapy for adult T-cell leukaemia-lymphoma has yet been established, and the prognosis for patients with this disease is very poor. Our results suggest that CPT-11 may be a promising agent for this disease. Further combination therapy with CPT-11 is needed to improve the therapy for ATL.

A nationwide multi-center cooperative phase II clinical study of irinotecan hydrochloride (CPT-11) was conducted to evaluate its efficacy in intractable malignant lymphoma and acute leukemia. In malignant lymphoma, one course of CPT-11 consisted of intravenous drip infusion at a dose of 40 mg/m2 once daily for 3 consecutive days, performed once a week. In acute leukemia, one course of CPT-11 consisted of intravenous drip infusion at a dose of 15 to 20 mg/m2 a day twice daily for 7 consecutive days (1 cycle), performed every 2 to 4 weeks. Among the 79 patients with malignant lymphoma and 50 patients with acute leukemia enrolled in the study, 66 and 41 patients, respectively, completed treatment. These patients had all undergone chemotherapy prior to treatment. Among the malignant lymphomas, the response rate in non-Hodgkin's lymphoma (NHL), including 9 CRs, was 42% (26/62, 95% CI: 30-54%); of these there was a response rate of 39% (5/13), including 1 CR, in adult T-cell leukemia (ATL) as well. In Hodgkin's disease (HD), on the other hand, there were no cases in which efficacy was demonstrated (0/4). The overall response rate in malignant lymphoma was 39% (26/66), and the response rate even among the recurrent intransigent cases was 42% (16/38). The 50% survival time (MST) in the 74 eligible cases of malignant lymphoma was 153 days. In acute leukemia, on the other hand, partial remission was observed in 2 of 17 cases (12%) of acute lymphocytic leukemia (ALL), but no cases of remission were observed in the 24 patients with acute myelogenous leukemia (AML). The overall remission rate in acute leukemia was 5% (2/41, 95% CI: 1-14%). The principal adverse effects were myelosuppression in malignant lymphoma and gastrointestinal symptoms, including diarrhea, nausea/vomiting, anorexia and abdominal pain, in both malignant lymphoma and acute leukemia, and there was little organ damage to the heart, liver or kidney. Myelosuppression and gastrointestinal adverse effects were severe in some of the patients, so caution is required. Based on the above findings, CPT-11 appears to be efficacious in the treatment of non-Hodgkin's lymphoma.
