Objective To evaluate the efficacy and safety of anakinra in combination with methotrexate (MTX) in patients with active rheumatoid arthritis (RA). Methods Patients with moderate-to-severe active RA who were receiving MTX for 6 consecutive months, with stable doses for ,3 months (those with disease duration of >6 months but <12 years) were randomized into 6 groups: placebo or 0.04, 0.1, 0.4, 1.0, or 2.0 mg/kg of anakinra administered in a single, daily, subcutaneous injection. The primary efficacy end point was the proportion of subjects who met the American College of Rheumatology 20% improvement criteria (attained an ACR20 response) at week 12. Results A total of 419 patients were randomized in the study. Patient demographics and disease status were similar in the 6 treatment groups. The ACR20 responses at week 12 in the 5 active treatment plus MTX groups demonstrated a statistically significant (P = 0.001) dose-response relationship compared with the ACR20 response in the placebo plus MTX group. The ACR20 response rate in the anakinra 1.0-mg/kg (46%; P = 0.001) and 2.0-mg/kg (38%; P = 0.007) dose groups was significantly greater than that in the placebo group (19%). The ACR20 responses at 24 weeks were consistent with those at 12 weeks. Similar improvements in anakinra-treated subjects were noted in individual ACR components, erythrocyte sedimentation rate, onset of ACR20 response, sustainability of ACR20 response, and magnitude of ACR response. Anakinra was safe and well tolerated. Injection site reaction was the most frequently noted adverse event, and this led to premature study withdrawal in 7% (1.0-mg/kg group) to 10% (2.0-mg/kg group) of patients receiving higher doses. Conclusion In patients with persistently active RA, the combination of anakinra and MTX was safe and well tolerated and provided significantly greater clinical benefit than MTX alone. [source]


Paliperidone palmitate , review of the efficacy, safety and cost of a new second-generation depot antipsychotic medication

INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 2 2010
L. Citrome
Summary Objective:, To describe the efficacy, safety and cost of paliperidone palmitate, a depot antipsychotic medication recently approved for the treatment of schizophrenia. Data sources:, A literature search was conducted by querying the websites http://www.pubmed.gov, http://www.fda.gov, http://www.accessdata.fda.gov/scripts/cder/drugsatfda and http://www.clinicaltrials.gov for the search term ,paliperidone palmitate'. Cost information was obtained from the pharmaceutical vendor servicing a local state-operated psychiatric facility. Study selection:, All available reports of studies were identified. Product labelling provided additional information. Data extraction:, Descriptions of the principal results and calculation of the number needed to treat (NNT) and number needed to harm (NNH) for relevant dichotomous outcomes were extracted from the study reports and synopses. Additional safety outcomes subject to NNH analysis were obtained from product labelling. Data synthesis:, Paliperidone palmitate is a newly available depot formulation of paliperidone (the 9-OH metabolite of risperidone). Upon injection into the deltoid or gluteal muscle, the release of the drug starts as early as day 1, reaches maximum plasma concentrations at 13 days and lasts for as long as 126 days. Maximum concentration following deltoid injection is approximately 28% higher compared with injection into the gluteal muscle, and thus paliperidone palmitate requires initiation by two initial deltoid injections spread 1 week apart to achieve therapeutic concentrations rapidly. Subsequent injections are at 4-week intervals. Acute efficacy was evidenced by four short-term double-blind, randomised, placebo-controlled, fixed-dose studies of acutely relapsed adult inpatients who met DSM-IV criteria for schizophrenia. NNT for a 30% or greater decrease in the Positive and Negative Syndrome Scale total score compared with placebo was consistently lower for the higher dose strengths of 156 and 234 mg, suggesting a therapeutic dose,response. Treatment with paliperidone palmitate at doses between 39 and 156 mg significantly delayed the time to recurrence of symptoms of schizophrenia after 24 weeks of maintained symptom stability. The NNT vs. placebo to avoid a recurrence of symptoms was 5 (95% CI 4,7). Overall, paliperidone palmitate was reasonably well tolerated, with low rates of extrapyramidal symptoms or body weight gain; however, these may be more common at higher doses. Injection site reactions occurred at a rate ranging from 4% to 10%, depending on the dose regimen, compared with 2% for the pooled placebo arms. The acquisition cost of a maintenance dose of paliperidone palmitate calculated on a per day basis is similar to that for risperidone microspheres, but about double the cost for oral paliperidone and approximately 19 times the cost of oral generic risperidone. Conclusions:, Paliperidone palmitate is efficacious for the acute and maintenance treatment of schizophrenia and is reasonably well tolerated. It offers several advantages over other available second-generation depot antipsychotics: it comes in prefilled syringes in a number of different dosage strengths; it does not require refrigeration; it does not require supplementation with oral antipsychotics; it can be administered once monthly; it can be administered with a very small bore needle; the injection volume is small; the injection site can be either the deltoid or gluteal muscles; it does not require an additional precautionary observation period after the injection. For patients for whom oral risperidone or paliperidone is otherwise effective, paliperidone palmitate offers a guaranteed delivery system that enhances adherence. However, the high acquisition cost of paliperidone palmitate will likely be an important obstacle to its routine use. [source]


Lobular panniculitis at the site of glatiramer acetate injections for the treatment of relapsing-remitting multiple sclerosis.

JOURNAL OF CUTANEOUS PATHOLOGY, Issue 4 2008
A report of two cases
Lipoatrophy and localized panniculitis have been described as rare complications of daily subcutaneous glatiramer acetate injections for the treatment of relapsing-remitting multiple sclerosis (MS). We describe the biopsies from two MS patients in a single neurologist's practice who developed clinical lesions of lipoatrophy at the sites of subcutaneous glatiramer acetate injections. These biopsies showed a lobular panniculitis with lipoatrophy that more closely resembled lupus panniculitis than previous reports of localized panniculitis at glatiramer acetate injection sites. In one case, the area of clinical lipoatrophy continued to enlarge for 6 months after stopping glatiramer acetate therapy, before stabilizing at its current size for the last 8 months. Injection site reactions to glatiramer acetate should be considered in the differential diagnosis of biopsies that show a lupus panniculitis-like appearance. Our observations indicate that glatiramer acetate induced panniculitis is common and may continue to progress after therapy has stopped. In this single neurologist's practice, 64% of the patients receiving daily glatiramer acetate injections had clinical evidence of lipoatrophy or panniculitis. Of 100 consecutive patients receiving therapy for MS between February and November 2006, 14 patients were on glatiramer acetate, 9 of whom had clinical lipoatrophy. [source]


Recall injection-site reactions associated with etanercept therapy: report of two new cases with immunohistochemical analysis

CLINICAL & EXPERIMENTAL DERMATOLOGY, Issue 6 2007
M. A. González-López
Summary Injection site reactions (ISRs) are the most common adverse effect reported with etanercept therapy. It has been observed that some patients treated with etanercept develop ,,recall ISRs'', that are reactions at sites where etanercept was previously injected after the last injection. Etanercept-associated recall ISRs have been scarcely published. We report two patients with rheumatoid arthritis who developed recall ISRs during etanercept therapy. Biopsy specimens from ISRs demonstrated a superficial perivascular lymphocytic infiltrated with a few eosinophils. Immunohistochemical study in both cases revealed that T cells bearing a CD4+ phenotype mostly composed the inflammatory infiltrate. Our observations suggest that ISRs may be mediated by classic cellular-hypersensitivity reactions directed by CD4+ T lymphocytes. [source]


Allogeneic retrovirally transduced, IL-2- and IFN-,-secreting cancer cell vaccine in patients with hormone refractory prostate cancer,a phase I clinical trial

THE JOURNAL OF GENE MEDICINE, Issue 7 2007
T. H. Brill
Background The purpose of this vaccine study was to determine the safety and feasibility of vaccination with an allogeneic prostate carcinoma cell line, LNCaP, expressing recombinant interleukin-2 (IL-2) and interferon-, (IFN-,) and to evaluate the efficacy of inducing tumor-specific immune responses in HLA-A2-matched patients with hormone refractory prostate cancer (HRPC). Methods In a dose-escalating phase I study, HLA-A2-matched HRPC patients received four vaccinations of irradiated allogeneic LNCaP cells retrovirally transduced to secrete IL-2 and IFN-, at study day 1, 15, 29 and 92 and subsequently every 91 days unless tumor progression was evident. Results Three patients receiving the first dose level (7.5 million cells) showed no evidence of dose-limiting toxicity or vaccine-related adverse events including autoimmunity. One of three patients receiving the second dose level (15 million cells) developed a transient self-limiting grade 3 local injection site reaction (ulceration) after the eighth vaccination. Vaccine-induced immune responses against a broad array of prostate tumor associated antigens were detected in all six patients. Two of the three patients receiving the higher dose showed a decline in serum prostate-specific antigen (PSA) values of more than 50%, with one patient remaining on protocol for 3 years. Conclusions Immunisation with the allogeneic LNCaP/IL-2/IFN-, vaccine is safe and feasible without any dose-limiting toxicity or autoimmunity. A 50% PSA decline was achieved in two of the six patients. This encouraging data provides the scientific rationale for further investigation of the vaccine in a phase II trial.

A phase II study of 5-day intravenous azacitidine in patients with myelodysplastic syndromes,

AMERICAN JOURNAL OF HEMATOLOGY, Issue 9 2009
Mike G. Martin
The approved 7-day schedule of subcutaneous azacitidine for myelodysplastic syndrome is associated with injection site reactions and bruising and may be inconvenient because of the need for weekend doses. Although pharmacokinetic data with IV azacitidine suggests equivalence, there are no efficacy data published. Patients with all myelodysplastic syndromes (MDS) FAB subtypes were enrolled and received 75 mg/m2/d of azacitidine by 20-min intravenous infusion for 5 days in every 28 days. Global methylation studies were performed at baseline and prior to Cycle 3. Twenty-five patients were enrolled and 22 were evaluable. Median age was 69.5 years; 9 (41%) patients had lower-risk disease (IPSS Low or Int-1) and 13 (59%) had higher-risk disease (IPSS Int-2 or High). Twenty-seven percent of patients responded (5 CRs and 1 PR). The median time to response was 108 days. The median PFS was 339 days (11.3 months), the median OS was 444 days (14.8 months) and the median duration of response (DOR) was 450 days (15.0 months). Global methylation studies suggest a greater degree of demethylation in responders. This regimen appeared to offer a PR + CR rate and median DOR somewhat similar to what has been reported with the 7-day subcutaneous regimen; however, OS was shorter. Am. J.

Evaluation of body mass index, pre-vaccination serum progesterone levels and anti-anthrax protective antigen immunoglobulin G on injection site adverse events following anthrax vaccination in women

PHARMACOEPIDEMIOLOGY AND DRUG SAFETY, Issue 11 2008
Yujia Zhang PhD
Abstract Background In 2002, CDC initiated the Anthrax Vaccination Program (AVP) to provide voluntary pre-exposure anthrax vaccination for individuals at high risk for exposure to Bacillus anthracis spores. The AVP offered an opportunity to investigate hypothesized reasons for a reported gender difference in injection site adverse events (AEs) following anthrax vaccine adsorbed (AVA). Objectives To evaluate in women the impact of body mass index (BMI), pre-vaccination serum progesterone levels, and pre-vaccination anti-anthrax protective antigen immunoglobulin G concentrations (anti-PA IgG) on the occurrence of AEs following subcutaneous AVA vaccination. Methods Participants' BMI was determined at enrollment. Also, pre-vaccination blood samples were assayed for serum progesterone and anti-PA IgG. Post-vaccination solicited AEs were recorded by participants using a 4-day diary card. Results Obese group had an elevated risk for arm soreness. Decreased pre-vaccination serum progesterone level was associated with arm swelling. Increased pre-vaccination anti-PA IgG was associated with itching on the arm; and within the obese group, was associated with arm swelling, lump or knot, redness, soreness, and warmth. Conclusions In AVA vaccinated women, obesity was associated with arm soreness and decreased pre-vaccination serum progesterone levels were associated with increased rate of arm swelling. Increased pre-vaccination anti-PA IgG may be associated with an increased frequency of itching on the arm, and in obese women, may increase the occurrence of arm swelling, lump or knot, redness, and warmth. Administering AVA according to a woman's menstrual phase may reduce the occurrence of certain injection site reactions. Copyright © 2008 John Wiley & Sons, Ltd. [source]


Short-term reactogenicity and gender effect of anthrax vaccine: analysis of a 1967,1972 study and review of the 1955,2005 medical literature,,

PHARMACOEPIDEMIOLOGY AND DRUG SAFETY, Issue 3 2007
Michael M. McNeil MD
Abstract Purpose In the 1960s, the Centers for Disease Control and Prevention (CDC) held the investigational new drug (IND) application for the anthrax vaccine and collected short-term safety data from approximately 16,000 doses administered to almost 7000 individuals. While some recent anthrax vaccine safety studies have suggested that women experience more injection site reactions (ISRs), to our knowledge the IND safety data were not previously examined for a gender-specific difference. Methods We identified and analyzed a subset of the IND study data representing a total of 1749 persons who received 3592 doses from 1967 to 1972. Original data collection forms were located and information extracted, including: vaccine recipient's name, age at vaccination, gender, dose number, date of vaccination, lot number, grading of ISR, presence and type of systemic reactions. Overall and gender-specific rates for adverse reactions to anthrax vaccine were calculated and we performed a multivariable analysis. Results We found an ISR was associated with 28% of anthrax vaccine doses; however, 87% of these were considered mild. Systemic reactions were uncommon (<1%) and most (70%) accompanied an ISR. Our dose-specific analysis by gender found women had at least twice the risk of having a vaccine reaction compared to men. Our age-adjusted relative risk for ISR in women compared to men was 2.78 (95%CI: 2.29, 3.38). Conclusions Our results for both overall and gender-specific reactogenicity are consistent with other anthrax safety studies. To date, possible implications of these gender differences observed for anthrax and other vaccines are unknown and deserve further study. Copyright © 2007 John Wiley & Sons, Ltd. [source]


A phase 1 trial of 2 dose schedules of ABT-510, an antiangiogenic, thrombospondin-1-mimetic peptide, in patients with advanced cancer,

CANCER, Issue 12 2008
Michael S. Gordon MD
Abstract BACKGROUND. ABT-510 is a substituted nonapeptide that mimics the antiangiogenic activity of the endogenous protein thrombospondin-1 (TSP-1). The current study was designed to establish the safety of ABT-510 in the treatment of patients with advanced malignancies on a once-daily (QD) and twice-daily dosing schedule. METHODS. Patients were randomly assigned to 1 of 6 dosing regimens: 20 mg, 50mg, or 100 mg QD or 10 mg, 25 mg, or 50 mg twice daily. ABT-510 was administered by subcutaneous bolus injection in cycles of 28 days. Tumor response and disease progression were monitored at 8-week intervals by computed tomography scan or magnetic resonance imaging. RESULTS. Thirty-six patients were randomly assigned in equal numbers to the 6 study regimens, with an additional 13 patients randomized to the 10-mg-twice-daily and 50-mg-twice-daily ABT-510 regimens. The expected pharmacokinetic target was achieved at all dose levels tested. The majority of adverse events were grade 1 or 2 (according to National Cancer Institute Common Toxicity Criteria [version 2]) and were not found to be dose related. The most frequently reported adverse events that were possibly related to ABT-510 included injection site reactions, asthenia, headache, and nausea. Grade 3 events considered to possibly be related included nausea, dyspnea, bone pain, constipation, vomiting, asthenia, and chills and tremors. One partial response was observed in a patient with carcinosarcoma who received 20 mg QD. The 6-month progression-free survival rate was 6%. Approximately 42% of patients (21 of 50 patients) had stable disease for ,3 months. CONCLUSIONS. ABT-510 can be administered at doses of 20 mg/day to 100 mg/day without significant toxicity. In the current study, minimal antitumor activity was observed, which was similar to observations in other single-agent antiangiogenic trials. Cancer 2008. © 2008 American Cancer Society. [source]
