To determine whether the addition of lisofylline (LSF) to idarubicin (12 mg/m2 daily x 3) + ara-C (1.5 g/m2 daily x 4) affects the rates of infection, serious infection, CR or mortality during remission induction of newly diagnosed AML, RAEB-t or RAEB, we randomized 70 patients to 3 mg/kg lisofylline or placebo every 6 h i.v., to begin 6 h before the first dose of idarubicin and to continue until recovery of neutrophil and platelet counts or for 28 days, whichever came first. Eligibility required that patients be below age 71 years, have no history of abnormal counts, or chemotherapy for a prior malignancy, and have a creatinine <1.6 mg/dl and bilirubin <3.0 mg/dl. The study was double-blinded and infections were tabulated separately and independently at MD Anderson and by a three-member outside panel of experts. Logistic regression was used to assess the relative effects of treatment arm (LSF or placebo), age, performance status, treatment site (laminar air flow room or not), and cytogenetics on rates of infection and serious infection following the first course of chemotherapy, and on CR rate. There were 84% and 87% concordance between the expert panel and MD Anderson enumerations of infection and serious infections, respectively. Both analyses found no significant (P < 0.05) differences between the rates of infection, or serious infection, in the placebo and LSF groups. CR, 60-day, and overall mortality rates were similar in the two groups, as were time to neutrophil and blood count recovery and outcome once in CR. Logistic regression analyses supported the above conclusions. Severe nausea/vomiting and mucositis were more frequent in the LSF group. Our results suggest that larger studies of LSF in newly diagnosed AML, RAEB-t, or RAEB are not warranted.

The efficiency and toxicity of treatment regimens for nonintensive cytoreduction in 57 outpatients with refractory acute leukemia (mean age 56 years, 51 AML, six ALL/AUL) were retrospectively studied. Seventeen patients received one treatment regimen, 19 patients two treatment regimens, and 21 patients three or more treatment regimens. The treatment regimens analyzed were 6-thioguanine p.o. (daily) (T), 6-thioguanine p.o. (4-7 days/week) + cytarabine s.c./i.v. (once a week) (T+C), 6-mercaptopurine p.o. (daily) (MP), 6-mercaptopurine p.o. (daily) + methotrexate p.o./i.v. (once a week) (MP+MTX), etoposide p.o. (daily) (E), and mitoxantrone i.v. (M). The median leukocyte count was higher for M (73 x 10(9)/l) than for the other treatment regimens (T: 27 x 10(9)/l, T+ C: 37 x 10(9)/l, MP: 24 x 10(9)/l, MP + MTX: 30 x 10(9)/l, E: 31 x 10(9)/l). A cytoreduction >50% in the peripheral blood was achieved by T in 11/19, by T+C in 7/11, by MP in 5/8, by MP+MTX in 3/6, by E in 3/4, and by M in 16/22 patients. The period of cytoreduction was regarded as the duration of response - T: median 53 days, range 5-98; T+C: median 61 days, range 14-226; MP: median 37 days, range 4-192; MP + MTX: median 58 days, range 36-59; E: median 121 days, range 26-159; M: median 39 days, range 8-78. T and T + C were well tolerated by all but three patients (stomatitis, diarrhea, WHO grade 2). MP was accompanied by a rise of transaminases (WHO 1-3) in 5/6 patients. E led to stomatitis (WHO 1,2) in 4/5 and M to nausea/vomiting (WHO 1,2) in 5/22 and to stomatitis (WHO 2) in 4/22 cases. The mean survival time after start of palliative cytoreduction was 16 weeks (2-65). In summary, 6-thioguanine +/- cytarabine was best tolerated with effective but in oral monotherapy - often protracted cytoreduction in 60% of patients. Mitoxantrone showed tolerable side effects and potent cytoreduction in 73% of patients even after ineffective palliative pretreatment. Palliative cytoreductive therapy does not reduce the quality of life and can prevent complications of significant leukocytosis in refractory acute leukemia.

Quality of life (QL) was evaluated in 101 patients with AML undergoing intensive and prolonged treatment at 12 sequential time points by using the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C 30 questionnaire and the profile of mood states scale (POMS). For those patients having completed the course of inpatient treatment (n=37), QL improved from the beginning of chemotherapy to the end of inpatient treatment. Patients who subsequently went off protocol did not differ significantly in their self-assessed QL when compared with patients who completed therapy. Fatigue was more closely related to QL than nausea/emesis or appetite loss, but did not correlate with hemoglobin levels.

The nematode Spirocerca lupi is a parasite of dogs with beetles of several species serving as intermediate hosts. The medical records of 50 dogs diagnosed with spirocercosis at the Hebrew University Veterinary Teaching Hospital (HUVTH) in Israel during 1991-1999 were retrospectively reviewed and compared to a control group (n=100). There was a seven-fold increase in the annual number of dogs diagnosed with spirocercosis during these years while the hospital caseload increased by 80%, indicating an emerging outbreak of this infection. Dogs from the greater Tel Aviv area were at the highest risk of being diagnosed with spirocercosis with 74% of the cases originating from this region compared to only 17% of the controls. The disease appeared to have a primarily urban pattern of distribution with a significantly higher percentage (P=0.025) of dogs from cities versus rural areas, as compared to the control group. Sixty-two percent of the cases were diagnosed during the colder months of December through April. The median age of infected dogs was 5 years, with dogs 1 year old or younger at the lowest risk of being diagnosed with spirocercosis. Large breeds were at a higher risk of infection in comparison to small breeds and the Labrador Retriever was significantly over represented (P=0.027) in the study group compared to the control population. The most common signs were vomiting or regurgitation (60%), pyrexia (24%), weakness (22%), respiratory abnormalities (20%), anorexia (18%), melena (18%) and paraparesis (14%). A caudal esophageal mass was identified by radiography in 53% of the dogs and spondylitis of the thoracic vertebrae in 33%. Fecal flotation was positive for S. lupi eggs in 80% of the dogs, and endoscopy was found to be the most sensitive diagnostic procedure and allowed diagnosis in 100% of the examined dogs. Fifty-three percent of the dogs were anemic and creatine kinase (CK) activities were elevated in 54%. Necropsy of 14 dogs revealed esophageal or gastric granulomas in 13 dogs, and an esophageal osteosarcoma in a single animal. Aortic aneurysms were found in six (43%) dogs. Out of 24, 15 dogs (63%) for which follow-up information was available died or were euthanized within 1 month of admission. The case-fatality rate decreased toward the end of the study period when improved therapy with avermectins became available.

HuM195 is a humanized, unconjugated, anti-CD33 monoclonal antibody. Fifty adult patients with relapsed or refractory AML were randomized to receive HuM195 at a dose of 12 or 36 mg/m(2) by intravenous infusion over 4 h on days 1-4 and 15-18. Patients with stable or responding disease received two additional cycles on days 29-32 and 43-46. HuM195 was given as first salvage therapy in 24 patients and as second or subsequent salvage therapy in 26 patients. Pretreatment blast percentage in the marrow was between 5 and 30% in 20 patients with the others having blast counts greater than 30%. The median age of patients was 62 years (range 26-86) and CD33 was detected in 95% of patients for whom immunophenotyping was available. Of 49 evaluable patients, two complete and one partial remission were observed. All three responses were in patients treated at the 12 mg/m(2) dose level and all had baseline blast percentages less than 30%. Decreases in blast counts ranging from 30 to 74% were seen in nine additional patients. Infusion-related events of fever and chills occurred in the majority of patients and were generally mild and primarily related to the first dose of antibody. No hepatic, renal or cardiac toxicities were observed and other adverse events such as nausea, vomiting, mucositis and diarrhea were uncommon or felt to be unrelated to HuM195. In addition, anti-HuM195 responses were not detected. HuM195 as a single agent has minimal, but observable, anti-leukemic activity in patients with relapsed or refractory AML and activity is confined to patients with low burden disease. No significant differences in clinical efficacy or toxicity were seen between the two dose levels of antibody. HuM195 was well tolerated with infusion-related fevers and chills the predominant toxicities seen. Meaningful clinical efficacy of this unconjugated monoclonal antibody may be realized only in patients with minimal residual disease, or in combination with chemotherapy.

From 1998 to 2001, 5 consecutive cases of AML/TMDS entered our hospital and achieved complete remission (CR) with continuous drip infusion of low-dose etoposide and low-dose Ara-C combined with mitoxantrone (MEtA regimen). The ages of the 5 patients (4 males and 1 female) ranged 32 to 50 years-old, respectively. WBCs were 1,560-45,150/microl, blasts were 12-62%. Bone marrow aspirates revealed trilineage myelodysplasia with various number of blasts. These patients had an acute onset and no preceding hematologic disorders. They were diagnosed M2/TMDS or M4/TMDS. Continuous drip infusion of etoposide (50 mg/body/day) and Ara-C (30 mg/body/day) were given for 11-14 days and a bolus injection of mitoxantrone (8 mg/m2) was added for 2-3 days. Patient 5 was given additional MIT (6.7 mg/m2 on day 6). All cases achieved CR in 21-24 days after the end of the therapy. Toxicities were nausea, vomiting, stomatitis, alopecia and fever due to infection. All were well tolerable, however. Two patients are alive more than 4 years without relapse. MEtA regimen is available for AML/TMDS.

Clofarabine (2-chloro-2'-fluoro-deoxy-9-beta-D-arabinofuranosyladenine) is a second-generation nucleoside analog with activity in acute leukemias. As clofarabine is a potent inhibitor of ribonucleotide reductase (RnR), we hypothesized that clofarabine will modulate ara-c triphosphate accumulation and increase the antileukemic activity of cytarabine (ara-C). We conducted a phase 1-2 study of clofarabine plus ara-C in 32 patients with relapsed acute leukemia (25 acute myeloid leukemia [AML], 2 acute lymphoblastic leukemia [ALL]), 4 high-risk myelodysplastic syndrome (MDS), and 1 blast-phase chronic myeloid leukemia (CML).(1) Clofarabine was given as a 1-hour intravenous infusion for 5 days (days 2 through 6) followed 4 hours later by ara-C at 1 g/m(2) per day as a 2-hour intravenous infusion for 5 days (days 1 through 5). The phase 2 dose of clofarabine was 40 mg/m(2) per day for 5 days. Among all patients, 7 (22%) achieved complete remission (CR), and 5 (16%) achieved CR with incomplete platelet recovery (CRp), for an overall response rate of 38%. No responses occurred in 3 patients with ALL and CML. One patient (3%) died during induction. Adverse events were mainly less than or equal to grade 2, including transient liver test abnormalities, nausea/vomiting, diarrhea, skin rashes, mucositis, and palmoplantar erythrodysesthesias. Plasma clofarabine levels generated clofarabine triphosphate accumulation, which resulted in an increase in ara-CTP in the leukemic blasts. The combination of clofarabine with ara-C is safe and active. Cellular pharmacology data support the biochemical modulation strategy.

The goal of this phase I study was to develop a novel schedule using oral etoposide and infusional topotecan as a continually alternating schedule with potentially optimal reciprocal induction of the nontarget topoisomerase. The initial etoposide dose was 15 mg m(-2) b.i.d. days (D)1-5 weeks 1,3,5,7,9 and 11, escalated 5 mg per dose per dose level (DL). Topotecan in weeks 2,4,6,8,10 and 12 was administered by 96 h infusion at an initial dose of 0.2 mg m(-2) day(-1) with a dose escalation of 0.1, then at 0.05 mg m(-2) day(-1). Eligibility criteria required no organ dysfunction. Two dose reductions or delays were allowed. A total of 36 patients with a median age of 57 (22-78) years, received a median 8 (2-19) weeks of chemotherapy. At DL 6, dose-limiting toxicities consisted of grade 3 nausea, vomiting and intolerable fatigue. Three patients developed a line-related thrombosis or infection and one subsequently developed AML. There was no febrile neutropenia. There were six radiologically confirmed responses (18%) and 56% of patients demonstrated a response or stable disease, typically with only modest toxicity. Oral etoposide 35 mg m(-2) b.i.d. D1-5 and 1.8 mg m(-2) 96 h (total dose) infusional topotecan D8-11 can be administered on an alternating continual weekly schedule for at least 12 weeks, with promising clinical activity.

Receptor activated tyrosine kinases such as c-kit, c-fms and PDGFR are known targets of inhibition by imatinib mesylate (Gleevec) and are expressed on AML blasts. Marrow stromal cells and monocytes express KIT ligand, M-CSF and PDGF and are therefore capable of activating survival pathways in these leukemic cells. Given the synergy in vitro between Ara-C and imatinib mesylate on AML cell growth inhibition, we initiated a Phase I study combining CLAG+imatinib mesylate in AML patients. Patients with relapsed, refractory AML or CML myeloid blast crisis were eligible to receive Cladribine 5mg/m(2) days 3-7, Cytarabine 2gm/m(2) days 3-7, G-CSF 300mcg days 2-7, and escalating doses of imatinib mesylate given on days 1-15. The level 1 Gleevec dose was 400mg, while level 2 was 600mg and the level 3 dose 800mg. A total of 16 patients were enrolled, 15 AML and 1 CML myeloid blast crisis. The dose escalation occurred as planned and there was no clear evidence of added toxicity due to imatinib mesylate. One patient with an extensive cardiac history died of cardiac causes on day 1 of therapy however no other deaths occurred within 30 days of starting therapy. One patient had a Grade 3 skin rash at dose level 2. The most common toxicities encountered during induction therapy were nausea, vomiting, rash and diarrhea that were transient and/or reversible. At the 800mg dose 1 patient developed a decline in cardiac ejection fraction on day 20 who later died of sepsis, so this was considered a dose limiting toxicity. Of 16 evaluable patients 11 achieved a hypocellular marrow after initial induction with 1 additional patient achieving a hypocellular marrow following a second course of the same regimen. Four patients (25%) achieved a complete morphologic response with normal cytogenetics, 2 patients (12.5%) achieved a complete morphologic response only and 1 patient had a complete response in the bone marrow but incomplete blood count recovery. The overall response rate was 43.8%. The median overall survival was 175 days (95% CI 16.24-333.76) and the median relapse free survival was 76 days. The addition of imatinib mesylate to CLAG was well tolerated with acceptable toxicities and response rates comparable to other salvage regimens. To assess the efficacy of imatinib mesylate in combination with CLAG, a larger phase II trial is now planned.

We conducted a multicenter postmarketing study to investigate the efficacy and safety of reinduction therapy with a high-dose cytarabine-containing regimen for pediatric patients with relapsed or refractory acute leukemia. Seven of 13 patients (53.8%) with ALL achieved complete or partial remission, and only 1 of 6 patients (16.7%) with AML achieved partial remission. The frequent non-hematologic adverse events were gastrointestinal toxicities, such as vomiting, diarrhea and abdominal pain, as well as pyrexia and headache. Infection appeared in 9 of 20 (45%) patients. There were two death during reinduction therapy. One died of invasive bronchopulmonary aspergillosis, and the other died of intracranial hemorrhage and renal failure. These results indicated that a high-dose cytarabine regimen is effective as reinduction therapy in pediatric patients with relapsed ALL, and supportive care is essential to prevent or control treatment-related adverse events, such as infection.
