[Title]: Fludarabine, cyclophosphamide, and mitoxantrone as initial therapy of chronic lymphocytic leukemia: high response rate and disease eradication.
[Abstract]: PURPOSE: Fludarabine, cyclophosphamide, and mitoxantrone (FCM) results in a high response rate in previously treated patients with chronic lymphocytic leukemia (CLL). The aim of this study was to investigate FCM as frontline therapy in CLL. EXPERIMENTAL DESIGN: Sixty-nine patients under the age of 65 years with active CLL were treated. Patients received six cycles of fludarabine 25 mg/m(2) i.v. x 3 days, cyclophosphamide 200 mg/m(2) i.v. x 3 days, and mitoxantrone 6 mg/m(2) i.v. x 1 day. Treatment outcome was correlated with clinical and biological variables. The clinical significance of eradicating minimal residual disease (MRD) was also analyzed. RESULTS: The overall response, MRD-negative complete response (CR), MRD-positive CR, nodular partial response (PR), and PR rates were 90%, 26%, 38%, 14%, and 12%, respectively. Severe (grades 3 or 4) neutropenia developed in 10% of the patients. Major and minor infections were reported in 1% and 8% of cases, respectively. Median response duration was 37 months. Patients with del(17p) failed to attain CR. Patients achieving MRD-negative CR had a longer response duration and overall survival than patients with an inferior response. Low serum lactate dehydrogenase levels, low ZAP-70 expression, and mutated IgV(H) genes predicted longer response duration. Finally, both low ZAP-70 and CD38 expression in leukemic cells correlated with MRD-negativity achievement. CONCLUSION: FCM induces a high response rate, including MRD-negative CRs in untreated patients with active CLL. Treatment toxicity is acceptable. Both high ZAP-70 and increased CD38 expression predict failure to obtain MRD-negative response. Patients in whom MRD can be eradicated have longer response duration and overall survival than those with inferior response. These results indicate that FCM can be an ideal companion for chemoimmunotherapy of patients with CLL.

[Title]: Long-term remission in schizophrenia and related psychoses with long-acting risperidone: results obtained in an open-label study with an observation period of 18 months.
[Abstract]: OBJECTIVE: To monitor long-term symptomatic tolerability and remission in patients with stable but suboptimally treated psychoses after switching to risperidone long-acting injectable (RLAI). METHOD: This subgroup analysis of the Switch to Risperidone Microspheres (StoRMi) open-label trial followed up patients with psychoses who were converted to RLAI for a period of 18 months or until RLAI became commercially available in their country of residence. It included patients from seven European countries. Dosage adjustments were performed as clinically necessary. The efficacy endpoint was achieving and maintaining remission, defined as absent to mild core schizophrenia symptoms for &gt; or = 6 months. A schizophrenia assessment was also completed and patients were monitored for the development of adverse events (AEs). Discontinuation rates were calculated based on Kaplan-Meier estimates where patients switching to commercial RLAI were used as censored observations. RESULTS: A total of 529 patients were followed for up to 18 months. At 18 months, the discontinuation rate was 55.7% based on Kaplan-Meier estimates. The median time to discontinuation was 15.7 months (95% CI (14.0; 17.5)). RLAI was generally well tolerated with most AEs mild-to-moderate in severity. 13% of patients discontinued treatment because of an AE. Body weight of patients increased by a mean A+/- SD of 1.0 A+/- 6.1 kg from treatment initiation to endpoint (p = 0.0001). Glucose-related AEs occurred in four patients (0.8%). Among those patients not meeting severity remission criteria at baseline, 44.8% were in remission at endpoint. Among those patients meeting severity criteria for remission at baseline, 84.2% were in remission at endpoint. A total of 93.7% of the patients who achieved or maintained remission at 6 months were in remission at endpoint. CONCLUSIONS: RLAI is safe during long-term treatment up to 18 months in adults requiring antipsychotics. Conversion to RLAI resulted in improved symptom control. Most patients achieved and maintained a sustained remission (&gt; or = 6 months) after conversion to RLAI.

[Title]: An evaluation of mu-opioid receptor (OPRM1) as a predictor of naltrexone response in the treatment of alcohol dependence: results from the Combined Pharmacotherapies and Behavioral Interventions for Alcohol Dependence (COMBINE) study.
[Abstract]: CONTEXT: Naltrexone hydrochloride treatment for alcohol dependence works for some individuals but not for everyone. Asn40Asp, a functional polymorphism of the mu-opioid receptor gene (OPRM1), might predict naltrexone response. OBJECTIVE: To evaluate whether individuals with alcoholism who are heterozygous (Asp40/Asn40) or homozygous (Asp40/Asp40) for the OPRM1 Asp40 allele respond better to naltrexone. DESIGN: Pharmacogenetic analysis conducted between January 1, 2001, and January 31, 2004. SETTING: Eleven academic sites in the COMBINE Study. PARTICIPANTS: Recently abstinent volunteers who met all 3 of the following conditions: (1) DSM-IV criteria for primary alcohol dependence; (2) participation in the COMBINE Study; and (3) availability of DNA. INTERVENTIONS: Alcoholic subjects were treated for 16 weeks with 100 mg of naltrexone hydrochloride (234 Asn40 homozygotes and 67 with at least 1 copy of the Asp40 allele) or placebo (235 Asn40 homozygotes and 68 with at least 1 copy of the Asp40 allele). All participants received medical management (MM) alone or with combined behavioral intervention (CBI). MAIN OUTCOME MEASURES: Time trends in percentage of days abstinent, percentage of heavy drinking days, and rates of good clinical outcome. RESULTS: Alcoholic subjects with an Asp40 allele receiving MM alone (no CBI) had an increased percentage of days abstinent (P = .07) and a decreased percentage of heavy drinking days (P = .04) if treated with naltrexone vs placebo, while those with the Asn40/Asn40 genotype showed no medication differences. If treated with MM alone and naltrexone, 87.1% of Asp40 carriers had a good clinical outcome, compared with only 54.8% of individuals with the Asn40/Asn40 genotype (odds ratio, 5.75; confidence interval, 1.88-17.54), while, if treated with placebo, 48.6% of Asp40 carriers and 54.0% of individuals with the Asn40/Asn40 genotype had a good clinical outcome (interaction between medication and genotype, P = .005). No gene x medication interactions were observed in those treated with both MM and CBI. CONCLUSIONS: These results confirm and extend the observation that the functionally significant OPRM1 Asp40 allele predicts naltrexone treatment response in alcoholic individuals. This relationship might be obscured, however, by other efficacious treatments. OPRM1 genotyping in alcoholic individuals might be useful to assist in selecting treatment options.

[Title]: Genetic variation in efflux transporters influences outcome to methotrexate therapy in patients with psoriasis.
[Abstract]: Methotrexate, an inexpensive first-line systemic therapy for moderate-to-severe psoriasis, is limited in its use by unpredictable efficacy and toxicity. This study was designed to test the hypothesis that single-nucleotide polymorphisms (SNPs) in methotrexate transmembrane transporters and adenosine receptors are associated with efficacy and/or toxicity of the drug. DNA was collected from 374 patients with chronic plaque psoriasis who had been treated with methotrexate. Phenotypic data on efficacy and toxicity were available. Haplotype tagging SNPs (r(2)&gt;0.8) across the relevant genes, with a minor allele frequency of &gt;5%, were selected from the HAPMAP phase II data. SNPs within the efflux transporter genes ABCC1 (ATP-binding cassette, subfamily C, member 1) and ABCG2 (ATP-binding cassette, subfamily G, member 2) are associated with good response to methotrexate therapy in patients with psoriasis; the former gene was also associated with the onset of toxicity. With one SNP in ABCC1, rs246240, the carriage of two copies of allele 1 gives an odds ratio of 2.2 (95% confidence interval: 1.3-3.6; P=0.001) for developing toxicity to methotrexate. These data indicate that knowledge of SNPs in genes relevant to methotrexate efflux may be important in selecting patients suitable for this therapy.

[Title]: Spotlight on risperidone in irritability associated with autistic disorder in children and adolescents.
[Abstract]: Risperidone (Risperdal), a psychotropic atypical antipsychotic agent, is thought to act via dopamine D(2) and serotonin 5-HT(2A) receptor antagonism. The clinical efficacy of oral risperidone in the treatment of bipolar mania and schizophrenia in adult patients is well established. In the US, risperidone is also approved for the treatment of irritability associated with autistic disorder in children and adolescents aged 5-16 years, for the treatment of schizophrenia in adolescents aged 13-17 years and, as monotherapy, for the short-term treatment of acute manic and mixed episodes associated with bipolar I disorder in children and adolescents aged 10-17 years. Oral risperidone treatment was better than placebo treatment in reducing irritability and other behavioural symptoms associated with autistic disorder in children and adolescents in two well designed short-term trials, with these benefits maintained in those receiving risperidone for up to 6 months. The drug had a clinically manageable tolerability profile, with most adverse events being of mild to moderate intensity. There are some aspects of treatment, such as weight gain, somnolence and hyperglycaemia, that require monitoring, and the long-term safety of risperidone in children and adolescents with autistic disorder remains to be fully determined. With these issues in mind, risperidone offers a valuable emerging option for the treatment of irritability associated with autistic disorder in children and adolescents.

[Title]: Ziprasidone in adolescents with autism: an open-label pilot study.
[Abstract]: INTRODUCTION: The antipsychotic drugs are the best-studied agents shown to reduce symptoms in autism, including hyperactivity, aggression, self-abusive behavior, temper tantrums, lability, irritability, social withdrawal, and stereotypical behaviors. However, significant weight gain has been associated with use of many atypical agents. Ziprasidone has been weight neutral in adult populations, but data from adolescents and patients with autism are sparse. However, ziprasidone administration has been associated with increases in the QTc. The purpose of this study was to collect pilot data on the efficacy and safety of ziprasidone in adolescents with autism, focusing on safety issues of weight gain and QTc. METHODS: Twelve adolescents with autism (mean age 14.5 +/- 1.8 years) were treated in a 6-week open pilot study. Ziprasidone dosage ranged from 20 to 160 mg/day (mean, 98.3 +/- 40.4 mg/day). The primary efficacy measure was the Clinical Global Impressions-Improvement item (CGI-I); other efficacy measures included the Aberrant Behavior Checklist and the Children's Psychiatric Rating Scale. RESULTS: Based on the CGI-I, 9 of 12 (75%) patients were treatment responders. Ziprasidone was weight neutral, and the QTc increased by a mean of 14.7 msec. Two subjects had acute dystonic reactions. Cholesterol decreased and prolactin remained the same. CONCLUSIONS: Ziprasidone shows promise as a treatment for adolescents with autism. More definitive trials are needed.

[Title]: The safety of dose-dense doxorubicin and cyclophosphamide followed by paclitaxel with trastuzumab in HER-2/neu overexpressed/amplified breast cancer.
[Abstract]: PURPOSE: Dose-dense (dd) doxorubicin and cyclophosphamide (AC) followed by paclitaxel (P) is superior to every 3-weekly AC followed by P. Given the demonstrated cardiac safety for trastuzumab (T) with conventionally scheduled AC followed by P, we tested the safety of dd AC followed by P with T. The primary end point was cardiac safety, and the secondary end points were time to recurrence and overall survival. METHODS: Patients with HER-2/neu immunohistochemistry (IHC) 3+ or fluorescent in situ hybridization (FISH)-amplified breast cancer and baseline left ventricular ejection fraction (LVEF) of &gt;or= 55% were enrolled, regardless of tumor size or nodal status. Treatment consisted of AC (60/600 mg/m(2)) x 4 followed by P (175 mg/m(2)) x 4 every 2-weekly with pegfilgrastim (6 mg on day 2) + T x1 year. LVEF by radionuclide scan was obtained at baseline, at months 2, 6, 9, and 18. RESULTS: From January 2005 to November 2005, 70 patients were enrolled. The median age was 49 years (range, 27 to 72 years); median LVEF at baseline was 68% (range, 55% to 81%). At month 2 in 70 of 70 patients, the median LVEF was 67% (range, 58% to 79%); at month 6 in 67 of 70 patients, it was 66% (range, 52% to 75%); at month 9 in 68 of 70 patients, it was 65% (range, 50% to 75%); and at month 18 in 48 of 70 patients, it was 66% (range, 57% to 75%). As of December 1, 2007, the median follow-up was 28 months (range, 25 to 35 months). One patient (1%) experienced congestive heart failure (CHF). There were no cardiac deaths. CONCLUSION: Dose-dense AC followed by P/T followed by T is feasible and is not likely to increase the incidence of cardiac events compared to established regimens.

[Title]: Acute bronchodilating effects of ipratropium bromide and theophylline in chronic obstructive pulmonary disease.
[Abstract]: The bronchodilator effects of a single dose of ipratropium bromide aerosol (36 micrograms) and short-acting theophylline tablets (dose titrated to produce serum levels of 10-20 micrograms/mL) were compared in a double-blind, placebo-controlled crossover study in 21 patients with stable, chronic obstructive pulmonary disease. Mean peak forced expiratory volume in 1 second (FEV1) increases over baseline and the proportion of patients attaining at least a 15% increase in the FEV1 (responders) were 31% and 90%, respectively, for ipratropium and 17% and 50%, respectively, for theophylline. The average FEV1 increases during the 6-hour observation period were 18% for ipratropium and 8% for theophylline. The mean duration of action was 3.8 hours with ipratropium and 2.4 hours with theophylline. While side effects were rare, those experienced after theophylline use did involve the cardiovascular and gastrointestinal systems. These results show that ipratropium is a more potent bronchodilator than oral theophylline in patients with chronic airflow obstruction.

[Title]: Telmisartan, ramipril, or both in patients at high risk for vascular events.
[Abstract]: BACKGROUND: In patients who have vascular disease or high-risk diabetes without heart failure, angiotensin-converting-enzyme (ACE) inhibitors reduce mortality and morbidity from cardiovascular causes, but the role of angiotensin-receptor blockers (ARBs) in such patients is unknown. We compared the ACE inhibitor ramipril, the ARB telmisartan, and the combination of the two drugs in patients with vascular disease or high-risk diabetes. METHODS: After a 3-week, single-blind run-in period, patients underwent double-blind randomization, with 8576 assigned to receive 10 mg of ramipril per day, 8542 assigned to receive 80 mg of telmisartan per day, and 8502 assigned to receive both drugs (combination therapy). The primary composite outcome was death from cardiovascular causes, myocardial infarction, stroke, or hospitalization for heart failure. RESULTS: Mean blood pressure was lower in both the telmisartan group (a 0.9/0.6 mm Hg greater reduction) and the combination-therapy group (a 2.4/1.4 mm Hg greater reduction) than in the ramipril group. At a median follow-up of 56 months, the primary outcome had occurred in 1412 patients in the ramipril group (16.5%), as compared with 1423 patients in the telmisartan group (16.7%; relative risk, 1.01; 95% confidence interval [CI], 0.94 to 1.09). As compared with the ramipril group, the telmisartan group had lower rates of cough (1.1% vs. 4.2%, P&lt;0.001) and angioedema (0.1% vs. 0.3%, P=0.01) and a higher rate of hypotensive symptoms (2.6% vs. 1.7%, P&lt;0.001); the rate of syncope was the same in the two groups (0.2%). In the combination-therapy group, the primary outcome occurred in 1386 patients (16.3%; relative risk, 0.99; 95% CI, 0.92 to 1.07); as compared with the ramipril group, there was an increased risk of hypotensive symptoms (4.8% vs. 1.7%, P&lt;0.001), syncope (0.3% vs. 0.2%, P=0.03), and renal dysfunction (13.5% vs. 10.2%, P&lt;0.001). CONCLUSIONS: Telmisartan was equivalent to ramipril in patients with vascular disease or high-risk diabetes and was associated with less angioedema. The combination of the two drugs was associated with more adverse events without an increase in benefit. (ClinicalTrials.gov number, NCT00153101 [ClinicalTrials.gov].).
