Selected AbstractsProphylactic use of anti-emetic medications reduced nausea and vomiting associated with exenatide treatment: a retrospective analysis of an open-label, parallel-group, single-dose study in healthy subjectsDIABETIC MEDICINE, Issue 10 2010C. Ellero Diabet. Med. 27, 1168,1173 (2010) Abstract Aims, Transient nausea and, to a lesser extent, vomiting are common adverse effects of exenatide that can be mitigated by dose titration and usually do not result in treatment discontinuation. This retrospective analysis of data from a phase 1, open-label, parallel-group, single-dose study in healthy subjects evaluated the effect of oral anti-emetics on exenatide-associated nausea and vomiting and on the pharmacokinetics of exenatide. Methods, A single subcutaneous dose (10 ,g) of exenatide was administered to 120 healthy subjects (19,65 years, BMI 23,35 kg/m2). Incidences of nausea and vomiting were compared between 60 subjects premedicated with two oral anti-emetics 30 min before the exenatide dose and 60 non-premedicated subjects. Similarly, the area under the concentration-time curve (AUC) and the maximum observed concentration (Cmax) of plasma exenatide concentrations over 8 h post-dose were compared. Results, Among all subjects [61% male, 32 ± 12 years, body mass index (BMI) 29.1 ± 3.4 kg/m2 (mean ± sd)], mild to moderate nausea was the most frequent adverse event after exenatide dosing. Vomiting was also observed. Subjects premedicated with anti-emetics experienced significantly less nausea and vomiting (16.7 and 6.7%, respectively) vs. non-premedicated subjects (61.7 and 38.3%, respectively; P -value < 0.0001 for both nausea and vomiting). The mean area under the concentration-time curve and the maximum observed concentration AUC and Cmax of plasma exenatide concentrations during 8 h post-dose were not significantly different between groups. Conclusion, Administration of oral anti-emetics before a single 10-,g exenatide dose was associated with significant reductions in treatment-emergent nausea and vomiting, with no discernible effect on the pharmacokinetics of exenatide. Use of anti-emetic therapy may provide a short-term strategy to minimize the nausea and vomiting associated with exenatide treatment. [source] Original Article: Treatment: Dose-dependent effects of the once-daily GLP-1 receptor agonist lixisenatide in patients with Type 2 diabetes inadequately controlled with metformin: a randomized, double-blind, placebo-controlled trialDIABETIC MEDICINE, Issue 9 2010R. E. Ratner Diabet. Med. 27, 1024,1032 (2010) Abstract Aims, To evaluate the dose,response relationship of lixisenatide (AVE0010), a glucagon-like peptide-1 (GLP-1) receptor agonist, in metformin-treated patients with Type 2 diabetes. Methods, Randomized, double-blind, placebo-controlled, parallel-group, 13 week study of 542 patients with Type 2 diabetes inadequately controlled [glycated haemoglobin (HbA1c) , 7.0 and < 9.0% (, 53 and < 75 mmol/mol)] on metformin (, 1000 mg/day) treated with subcutaneous lixisenatide doses of 5, 10, 20 or 30 ,g once daily or twice daily or placebo. The primary end-point was change in HbA1c from baseline to 13 weeks in the intent-to-treat population. Results, Lixisenatide significantly improved mean HbA1c from a baseline of 7.55% (59.0 mmol/mol); respective mean reductions for 5, 10, 20 and 30 ,g doses were 0.47, 0.50, 0.69 and 0.76% (5.1, 5.5, 7.5 and 8.3 mmol/mol), on once-daily and 0.65, 0.78, 0.75 and 0.87% (7.1, 8.5, 8.2 and 9.5 mmol/mol) on twice-daily administrations vs. 0.18% (2.0 mmol/mol) with placebo (all P < 0.01 vs. placebo). Target HbA1c < 7.0% (53 mmol/mol) at study end was achieved in 68% of patients receiving 20 and 30 ,g once-daily lixisenatide vs. 32% receiving placebo (P < 0.0001). Dose-dependent improvements were observed for fasting, postprandial and average self-monitored seven-point blood glucose levels. Weight changes ranged from ,2.0 to ,3.9 kg with lixisenatide vs. ,1.9 kg with placebo. The most frequent adverse event was mild-to-moderate nausea. Conclusions, Lixisenatide significantly improved glycaemic control in mildly hyperglycaemic patients with Type 2 diabetes on metformin. Dose,response relationships were seen for once- and twice-daily regimens, with similar efficacy levels, with a 20 ,g once-daily dose of lixisenatide demonstrating the best efficacy-to-tolerability ratio. This new, once-daily GLP-1 receptor agonist shows promise in the management of Type 2 diabetes to be defined further by ongoing long-term studies. [source] Adjuvant topical therapy with a cannabinoid receptor agonist in facial postherpetic neuralgiaJOURNAL DER DEUTSCHEN DERMATOLOGISCHEN GESELLSCHAFT, Issue 2 2010Ngoc Quan Phan Summary Background: Postherpetic neuralgia is a frequent adverse event in herpes zoster patients and difficult to treat. Conventional analgetic therapy often fails to reduce the burning pain transmitted by unmyelinated nerve fibers. These nerves express cannabinoid receptors which exert a role in modulation of nociceptive symptoms. Therefore, topical therapy with cannabinoid receptor agonist seems likely to suppress local burning pain. Patients and methods: In an open-labeled trial, 8 patients with facial postherpetic neuralgia received a cream containing the cannabinoid receptor agonist N-palmitoylethanolamine. The course of symptoms was scored with the visual analog scale. Results: 5 of 8 patients (62.5 %) experienced a mean pain reduction of 87.8 %. Therapy was tolerated by all patients. No unpleasant sensations or adverse events occurred. Conclusions: Topical cannabinoid receptor agonists are an effective and well-tolerated adjuvant therapy option in postherpetic neuralgia. [source] Alfuzosin 10 mg once daily for treating benign prostatic hyperplasia: a 3-year experience in real-life practiceBJU INTERNATIONAL, Issue 7 2008Guy Vallancien OBJECTIVES To assess the 3-year efficacy and safety of the selective ,1 -blocker alfuzosin at 10 mg once daily in men with lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH) in ,real-life practice'. The influence of treatment response on the risk of acute urinary retention (AUR) and BPH-related surgery was also analysed. PATIENTS AND METHODS In all, 689 European men (mean age 67.6 years) were enrolled by general practitioners in a 3-year open-label study with alfuzosin at 10 mg once daily. They were asked to complete the International Prostate Symptom Score (IPSS), its eighth question (bother score), and the Danish Prostatic Symptom Score for sexual function (DAN-PSSsex). Efficacy was analysed at the endpoint in the intent-to-treat population. The impact of baseline variables (age, PSA level, IPSS and bother severity) and dynamic variables (IPSS worsening of ,4 points and bother at the last available assessment under treatment) on the risk of AUR and BPH-related surgery was evaluated. RESULTS With alfuzosin, IPSS improved by 6.4 points (,33.4%) from baseline (P < 0.001), reaching ,3 points and >6 points in 71.3% and 47.2% of men, respectively. There were also significant (P < 0.001) improvements from baseline in nocturia (,0.8, ,25.5%), bother score (,1.7, ,40.7%) and DAN-PSSsex weighted scores with treatment. Symptom relief was rapid and maintained over 3 years. Overall, 78 men (12.4%) had an IPSS worsening of ,4 points, 16 (2.6%) had AUR, and 36 (5.7%) required BPH-related surgery. Symptom deterioration during treatment and high baseline PSA values were the best predictors of AUR and BPH-related surgery. Alfuzosin was well tolerated, dizziness being the most frequent adverse event (4.5%) possibly related to vasodilatation. Ejaculatory disorders were uncommon (0.4%). Changes in blood pressure remained marginal, including in men aged ,65 years and those receiving antihypertensive agents. CONCLUSION Alfuzosin administered for 3 years at 10 mg once daily in real-life practice is effective and well tolerated. High PSA values and symptom worsening under treatment appear the best predictors of AUR and BPH-related surgery in the long term. Treatment with alfuzosin might thus help to identify patients at risk of LUTS/BPH progression in order to optimize their management. [source] Response of refractory colitis to intravenous or oral tacrolimus (FK506)INFLAMMATORY BOWEL DISEASES, Issue 5 2002Dr. Klaus Fellermann Abstract Intravenous cyclosporine has proven to be an alternative to emergency colectomy in steroid-refractory ulcerative colitis, whereas the experience with FK506 is limited. In this report we compare intravenous to oral FK506 treatment in 38 patients with refractory ulcerative (n = 33) or indeterminate (n = 5) colitis. FK506 was started intravenously in the first group (n = 18) at a dose of 0.01 to 0.02 mg/kg up to 14 days, followed by 0.1 to 0.2 mg/kg orally, or was started orally at this dose in a second group (n = 20). Additional azathioprine/6-mercaptopurine was given and steroids were tapered in responding patients, followed by a dose reduction of FK506. Clinical disease activity and laboratory parameters were assessed to evaluate efficacy and safety. Primary objectives were the induction of remission (Truelove index of mild) and colectomy-free survival. Treatment lasted for a mean of 7.6 months, and the mean observation period was 16.2 months. Eighteen of 38 patients improved within 14 days, and a complete remission was achieved in 13 patients after 1 month. A colectomy within 1 month was performed in 3 of 38 patients. The overall colectomy rate was 34%. One-half of the patients with a minimum follow-up of 2 years required a colectomy. Intravenous and per oral administration were equally safe and effective. The most frequent adverse events included tremor, hyperglycemia, hypertension, and infection, but none were severe. Renal impairment was rare and subsided upon drug withdrawal. In conclusion, FK506 is effective in the treatment of refractory colitis with per oral dosing being equivalent to intravenous administration. [source] Re-treatment of chronic hepatitis C patients after relapse: efficacy of peginterferon-alpha-2a (40 kDa) and ribavirinJOURNAL OF VIRAL HEPATITIS, Issue 7 2006C. Berg Summary., We conducted a randomized multinational study to determine whether 48 weeks of re-treatment with peginterferon-alpha-2a (40 kDa) plus ribavirin would induce a sustained virological response (SVR) in relapsed chronic hepatitis C patients. Patients who had previously relapsed during 24 weeks of untreated follow-up, after having achieved an end-of-treatment virological response with 24 weeks of peginterferon-alpha-2a (40 kDa)/ribavirin combination therapy, within a phase III trial, were studied. Although the recommended dosage was the same as that used at the end of the initial trial, adjustments were permitted. Data on serious adverse events, or adverse events that resulted in dose reductions or discontinuations, were collected. Following re-treatment, the overall SVR rate in the 64 patients was 55%. The SVR rates in patients infected with hepatitis C virus (HCV) genotype 1 and non-1 genotypes were 51% and 63%, respectively. Early (week 12) virological responses were seen in 39 patients (61%) and were predictive of an SVR. Re-treatment was well tolerated. The most frequent adverse events recorded were fatigue (5%) and abdominal pain (3%). Dosages of peginterferon-alpha-2a (40 kDa) and/or ribavirin were modified because of adverse events in 3% and 13% of patients, and because of laboratory abnormalities in 23% and 5% of patients, respectively. Thus, a 48-week course of peginterferon-alpha-2a (40 kDa) plus ribavirin induces an SVR in 55% of patients who relapsed during follow-up after 24 weeks of combination therapy. Physicians should not hesitate to offer re-treatment to patients who relapse after an initial, 24-week course of combination therapy, or who have prematurely stopped treatment because, for example, of laboratory abnormalities. [source] Efficacy and Safety of Two Dosing Regimens of Tadalafil and Patterns of Sexual Activity in Men with Diabetes Mellitus and Erectile Dysfunction: Scheduled Use vs.THE JOURNAL OF SEXUAL MEDICINE, Issue 3 2006On-Demand Regimen Evaluation (SURE) Study in 14 European Countries ABSTRACT Aim., The aim of this article is to evaluate the efficacy and safety of 20-mg tadalafil taken on demand or three times per week and its effect on the sexual activity of patients with diabetes mellitus and erectile dysfunction (ED). Methods., The scheduled use vs. on-demand regimen evaluation (SURE) was a randomized, crossover, open-label study with 4,262 patients in 14 European countries. The efficacy measures for the 762 patients with diabetes and ED included changes from baseline in the erectile function (EF) domain of the International Index of Erectile Function (IIEF), and the proportion of "yes" responses to patient Sexual Encounter Profile (SEP) questions 2 (SEP2) and 3 (SEP3). The treatment satisfaction was measured with responses to SEP question 4 (SEP4) and SEP question 5 (SEP5), and sexual attempts data were collected. Patient preference for either regimen was determined by the treatment preference question (TPQ). Results., At end point on both regimens, the mean IIEF EF domain score was 22, and >40% of the patients had a normal EF domain score (,26). The proportion of "yes" responses was ,73% for SEP2 (penetration), ,58% for SEP3 (successful intercourse), >46% for SEP4 (hardness of erection), and ,45% for SEP5 (overall satisfaction). Efficacy was maintained up to 36 hours post-dosing. More than 70% of sexual attempts while on the three-times-per-week regimen and approximately 50% of the attempts on the on-demand treatment occurred >4 hours post-dosing. Tadalafil was well tolerated, with dyspepsia and headache as the most frequent adverse events reported. Treatment preference was 57.2% for on demand and 42.8% for three times per week. Conclusions., Tadalafil, when taken on demand or three times per week, is efficacious and safe in men with diabetes and ED. Buvat J, van Ahlen H, Schmitt H, Chan M, Kuepfer C, and Varanese L.

[source] Phase 1 Dose-Escalation Study of CP-690 550 in Stable Renal Allograft Recipients: Preliminary Findings of Safety, Tolerability, Effects on Lymphocyte Subsets and PharmacokineticsAMERICAN JOURNAL OF TRANSPLANTATION, Issue 8 2008E. Van Gurp CP-690 550 inhibits Janus kinase 3 with nanomolar potency. In this dose-escalation study, we assessed the safety, tolerability, effects on lymphocyte subsets, and pharmacokinetics of CP-690 550 when coadministered with mycophenolate mofetil in stable renal allograft recipients for 28 days. Twenty-eight patients were enrolled. Six patients received CP-690 550 5 mg twice daily (BID), 6 patients received 15 mg BID, 10 patients received 30 mg BID, and 6 patients received placebo. The most frequent adverse events were infections and gastrointestinal (abdominal pain, diarrhea, dyspepsia, and vomiting). CP-690 550 15 mg BID and 30 mg BID were associated with a mean decrease in hemoglobin from baseline of 11% and a mean decrease in absolute natural killer cell counts of 50%. CP-690 550 30 mg BID was also associated with a mean increase in absolute CD19+ B-lymphocytes of 130%. There were no changes in the number of neutrophils, total lymphocytes, platelets, or CD4+ or CD8+ T cells; clinical chemistry; vital signs; or electrocardiograms from the pretreatment baseline. Administration of CP-690 550 without a concomitant calcineurin inhibitor resulted in CP-690 550 exposures consistent with previous studies in nontransplant subjects. Additional dose-ranging studies are warranted to evaluate the safety and efficacy of CP-690 550 in renal transplant recipients over longer treatment duration. [source] Phase I/II and pharmacokinetic study of cladribine with 2-h infusion in Japanese patients with relapsed indolent B-cell lymphoma mostly pretreated with rituximabCANCER SCIENCE, Issue 7 2009Kensei Tobinai We conducted a phase I/II study to investigate the toxicity, pharmacokinetics, and efficacy profiles of cladribine with 2-h intravenous infusion for five consecutive days every four weeks in Japanese patients with relapsed indolent B-cell lymphoma. This was a dose-escalation study to confirm the safety of the doses which have been recommended for Caucasian patients (phase I), and to further evaluate the efficacy and safety (phase II). In the phase I portion for nine patients, no dose-limiting toxicities were observed at levels 1 (0.09 mg/kg/day, n = 3) and 2 (0.12 mg/kg/day, n = 6). No appreciable accumulation of plasma cladribine concentration was suggested. We enrolled a total of 20 patients, and an additional 14 patients in the phase II portion at level 2 (0.12 mg/kg/day). Eighteen patients, including 13 with follicular lymphoma, were eligible for efficacy evaluation, and 15 (83%) were pretreated with rituximab. The overall response rate was 50% (9/18; 80% confidence interval, 35,65%), with 11% (2/18) complete response. With a median follow-up of 296 days, the estimated median time to progression for 18 eligible patients was 382 days. The most frequent adverse events were hematologic toxicities, including grade 4 neutropenia. Non-hematologic toxicities were mild. In conclusion, cladribine with 2-h intravenous infusion for five consecutive days every four weeks is effective with acceptable toxicities for Japanese patients with relapsed indolent B-cell lymphoma, including those pretreated with rituximab.

Arbizu Objective, A protocol system is being used in Spain for the prescription of innovative drugs including interferon beta-1b (IFN,-1b). Petitions for dispensing and reimbursement are based on the inclusion and exclusion criteria of pivotal trials, and are reviewed individually for approval by specialist committees. To estimate the performance of IFN,-1b in the clinical setting, data collected by the INSALUD and regional health services of Andalusia and Catalonia, together responsible for the healthcare of nearly 30 million individuals, were compiled in a common database for analysis. Methods, Data comprise demographic and disease characteristics at the time of petition and at follow-up 3 months after treatment initiation and every 6 months thereafter. Efficacy was estimated by mean number of relapses per year, proportion of relapse-free patients, and disease progression as measured by the Expanded Disability Status Scale (EDSS). Safety parameters included adverse events and laboratory analyses. Results, Between September 1995 and database cutoff in mid-1998, petitions of 1419 patients were approved for IFN,-1b treatment. Patients were homogenous across the three databases and in the subgroups of patients completing 1 year (n=940) and 2 years (n=302) of treatment. There was a marked decrease in the mean number of relapses in the first 12 months of IFN,-1b treatment for the 938 patients documented for 12 months, with a mean of 0.4 (±0.7 SD) relapses per patient and year, and a 2-year mean of 0.9 (±1.20 SD) in the 302 patients documented for 24 months. Of the 938 patients followed for ,12 months, 505 (53.8%) were documented as being relapse-free during 12 months of treatment, and 146 (48.3%) of the 302 patients followed for ,24 months, were relapse-free during 24 months of treatment. There were no differences in mean or median EDSS scores between baseline and months 12 and 24. Skin disorders were the most frequent adverse events, reported in over one-third of all patients; there were 159 injection site events, most frequently erythema (115 events). Systemic AEs pointing towards flu-like symptoms were reported in 288 of 1419 patients (20.3%). Leukopenia was the most frequently reported laboratory event. Elevations in liver transaminases were noted for 12 patients (0.8%) with SGOT increase and 7 (0.5%) with SGPT increase. Conclusion, The protocol system has helped make IFN, treatment available to 8,10% of the estimated 15,000,18,000 MS patients in the regions studied. In terms of efficacy, IFN,-1b performed in line with the pivotal study results. The safety profile of IFN,-1b was consistent with the published findings and the drug labelling, and no new side effects or increased incidence of known side effects was observed.
