Efficacy and tolerability of naproxen/esomeprazole magnesium tablets compared with non-specific NSAIDs and COX-2 inhibitors: a systematic review and network analyses.

ABSTRACT: Non-steroidal anti-inflammatory drugs (NSAIDs), such as non-selective NSAIDs (nsNSAIDs) or selective cyclooxygenase-2 (COX-2) inhibitors, are commonly prescribed for arthritic pain relief in patients with osteoarthritis (OA), rheumatoid arthritis (RA), or ankylosing spondylitis (AS). Treatment guidelines for chronic NSAID therapy include the consideration for gastroprotection for those at risk of gastric ulcers (GUs) associated with the chronic NSAID therapy. The United States Food and Drug Administration has approved naproxen/esomeprazole magnesium tablets for the relief of signs and symptoms of OA, RA, and AS, and to decrease the risk of developing GUs in patients at risk of developing NSAID-associated GUs. The European Medical Association has approved this therapy for the symptomatic treatment of OA, RA, and AS in patients who are at risk of developing NSAID-associated GUs and/or duodenal ulcers, for whom treatment with lower doses of naproxen or other NSAIDs is not considered sufficient. Naproxen/esomeprazole magnesium tablets have been compared with naproxen and celecoxib for these indications in head-to-head trials. This systematic literature review and network meta-analyses of data from randomized controlled trials was performed to compare naproxen/esomeprazole magnesium tablets with a number of additional relevant comparators. For this study, an original review examined MEDLINE®, Embase®, and the Cochrane Controlled Trials Register from database start to April 14, 2009. Using the same methodology, a review update was conducted to December 21, 2009. The systematic review and network analyses showed naproxen/esomeprazole magnesium tablets have an improved upper gastrointestinal tolerability profile (dyspepsia and gastric or gastroduodenal ulcers) over several active comparators (naproxen, ibuprofen, diclofenac, ketoprofen, etoricoxib, and fixed-dose diclofenac sodium plus misoprostol), and are equally effective as all active comparators in treating arthritic symptoms in patients with OA, RA, and AS. Naproxen/esomeprazole magnesium tablets are therefore a valuable option for treating arthritic symptoms in eligible patients with OA, RA, and AS.

Project description:HCP1004 is a newly developed fixed-dose combination of naproxen (500 mg) and esomeprazole strontium (20 mg) that is used in the treatment of rheumatic diseases and can reduce the risk of nonsteroidal anti-inflammatory drug-associated ulcers. The aim of this study was to evaluate the pharmacokinetics (PK) and safety of HCP1004 compared to VIMOVO(®) (a marketed fixed-dose combination of naproxen and esomeprazole magnesium).An open-label, randomized, two-treatment, two-sequence crossover, single-dose clinical study was conducted in 70 healthy volunteers. In each period, a reference (VIMOVO(®)) or test (HCP1004) drug was administered orally, and serial blood samples for PK analysis were collected up to 72 hours after dosing. To evaluate the PK profiles, the maximum plasma concentration (Cmax) and the area under the concentration-time curve from 0 to the last measurable time (AUC0-t) were estimated using a noncompartmental method. Safety profiles were evaluated throughout the study.Sixty-six of the 70 subjects completed the study. The Cmax (mean ± standard deviation) and AUC0-t (mean ± standard deviation) for naproxen in HCP1004 were 61.67 ± 15.16 µg/mL and 1,206.52 ± 166.46 h · µg/mL, respectively; in VIMOVO(®); these values were 61.85 ± 14.54 µg/mL and 1,211.44 ± 170.01 h · µg/mL, respectively. The Cmax and AUC0-t for esomeprazole in HCP1004 were 658.21 ± 510.91 ng/mL and 1,109.11 ± 1,111.59 h · ng/mL, respectively; for VIMOVO(®), these values were 595.09 ± 364.23 ng/mL and 1,015.12 ± 952.98 h · ng/mL, respectively. The geometric mean ratios and 90% confidence intervals (CIs) (HCP1004 to VIMOVO(®)) of the Cmax and AUC0-t of naproxen were 0.99 (0.94-1.06) and 1.00 (0.98-1.01), respectively. For esomeprazole, the geometric mean ratios (90% CI) for the Cmax and AUC0-t were 0.99 (0.82-1.18) and 1.04 (0.91-1.18), respectively. The overall results of the safety assessment showed no clinically significant issues for either treatment.The PK of HCP1004 500/20 mg was comparable to that of VIMOVO(®) 500/20 mg for both naproxen and esomeprazole after a single oral dose. Both drugs were well-tolerated without any safety issues.

Project description:The use of peptide-drug conjugates is emerging as a powerful strategy for targeted drug delivery. Previously, we have found that peptides conjugated to a non-steroidal anti-inflammatory drug (NSAID), more specifically naproxen-dehydrodipeptide conjugates, readily form nanostructured fibrilar supramolecular hydrogels. These hydrogels were revealed as efficacious nano-carriers for drug delivery applications. Moreover, the incorporation of superparamagnetic iron oxide nanoparticles (SPIONs) rendered the hydrogels responsive to external magnetic fields, undergoing gel-to-solution phase transition upon remote magnetic excitation. Thus, magnetic dehydrodipeptide-based hydrogels may find interesting applications as responsive Magnetic Resonance Imaging (MRI) contrast agents and for magnetic hyperthermia-triggered drug-release applications. Supramolecular hydrogels where the hydrogelator molecule is endowed with intrinsic pharmacological properties can potentially fulfill a dual function in drug delivery systems as (passive) nanocariers for incorporated drugs and as active drugs themselves. In this present study, we investigated the pharmacological activities of a panel of naproxen-dehydrodipeptide conjugates, previously studied for their hydrogelation ability and as nanocarriers for drug-delivery applications. A focused library of dehydrodipeptides, containing N-terminal canonical amino acids (Phe, Tyr, Trp, Ala, Asp, Lys, Met) N-capped with naproxen and linked to a C-terminal dehydroaminoacid (?Phe, ?Abu), were evaluated for their anti-inflammatory and anti-cancer activities, as well as for their cytotoxicity to non-cancer cells, using a variety of enzymatic and cellular assays. All compounds except one were able to significantly inhibit lipoxygenase (LOX) enzyme at a similar level to naproxen. One of the compounds 4 was able to inhibit the cyclooxygenase-2 (COX-2) to a greater extent than naproxen, without inhibiting cyclooxygenase-1 (COX-1), and therefore is a potential lead in the search for selective COX-2 inhibitors. This hydrogelator is a potential candidate for dual COX/LOX inhibition as an optimised strategy for treating inflammatory conditions.

Project description:Non-steroidal anti-inflammatory drugs (NSAIDs) are used for relieving pain and inflammation accompanying numerous disease states. The primary therapeutic mechanism of these widely used drugs is the inhibition of cyclooxygenase 1 and 2 (COX1, 2) enzymes that catalyze the conversion of arachidonic acid into prostaglandins. At higher doses, NSAIDs are used for prevention of certain types of cancer and as experimental treatments for Alzheimer's disease. In the immune system, various NSAIDs have been reported to influence neutrophil function and lymphocyte proliferation, and affect ion channels and cellular calcium homeostasis. Transient receptor potential melastatin 7 (TRPM7) cation channels are highly expressed in T lymphocytes and are inhibited by Mg2+, acidic pH, and polyamines. Here, we report a novel effect of naproxen, ibuprofen, salicylate, and acetylsalicylate on TRPM7. At concentrations of 3-30mM, they reversibly inhibited TRPM7 channel currents. By measuring intracellular pH with the ratiometric indicator BCECF, we found that at 300μM to 30mM, these NSAIDs reversibly acidified the cytoplasm in a concentration-dependent manner, and propose that TRPM7 channel inhibition is a consequence of cytosolic acidification, rather than direct. NSAID inhibition of TRPM7 channels was slow, voltage-independent, and displayed use-dependence, increasing in potency upon repeated drug applications. The extent of channel inhibition by salicylate strongly depended on cellular PI(4,5)P2 levels, as revealed when this phospholipid was depleted with voltage-sensitive lipid phosphatase (VSP). Salicylate inhibited heterologously expressed wildtype TRPM7 channels but not the S1107R variant, which is insensitive to cytosolic pH, Mg2+, and PI(4,5)P2 depletion. NSAID-induced acidification was also observed in Schneider 2 cells from Drosophila, an organism that lacks orthologous COX genes, suggesting that this effect is unrelated to COX enzyme activity. A 24-h exposure to 300μM-10mM naproxen resulted in a concentration-dependent reduction in cell viability. In addition to TRPM7, the described NSAID effect would be expected to apply to other ion channels and transporters sensitive to intracellular pH.

Project description:Juvenile idiopathic arthritis (JIA) is an inflammatory arthritis of unknown etiology, which lasts for greater than 6 weeks with onset before 16 years of age. JIA is the most common chronic rheumatic disease in children. NSAIDs have been the mainstay of initial management with naproxen (NAP) being commonly used, but they may cause serious side effects such as gastric ulcers which can be reduced by concomitant administration of proton pump inhibitors, such as esomeprazole (ESO).Primary objective was to evaluate the safety and tolerability of 3 fixed doses of NAP/ESO in JIA patients aged 12 to 16 years. Forty-six children and adolescents with JIA by International League of Associations for Rheumatology criteria, mean age of 13.6 years, from 18 US sites were prospectively enrolled over 2 years and followed for up to 6 months. Doses of the NAP/ESO fixed combination were based on baseline weight. The exploratory efficacy outcome was assessed with the ACR Pediatric-30, -?50, -?70, -?90 Response and the Childhood Health Assessment Questionnaire (CHAQ) discomfort and functional scores at months 1, 3, and 6 as change from baseline. Occurrence and causality were assessed for treatment emergent AEs (TEAEs) and discontinuations were monitored monthly.Forty-six patients received at least 1 dose of naproxen/esomeprazole and 36 completed the trial. Thirty-seven (80.4%) had at least 1 treatment emergent adverse event (TEAE) and, with the exception of 2 events in one patient, all of the TEAEs were mild or moderate. Frequent TEAEs (?5% of patients) were upper respiratory tract and gastrointestinal related. Eleven (23.9%) had at least 1 TEAE considered to be related to study drug. Four patients (8.7%) discontinued due to a TEAE with one of these being the only serious AE reported, acute hepatitis. Mean number of active joints at baseline was 3.1. Improvement in JIA signs and symptoms occurred at most assessments and by month 6, the percentage of patients with an ACR Pediatric-30, -?50, -?70, and?-?90 Response was 47.1, 38.2, 32.4, and 17.6%, respectively. The percent of patients achieving ACR Pediatric response increased over time. CHAQ discomfort improved at each assessment and functional scores improved at all assessments for 'Arising, Walking, and Activities' with several improved for 'Dressing and Grooming, Eating, Hygiene, and Grip'. There was no indication of a dose-related efficacy effect.NAP/ESO was well tolerated in JIA patients aged 12 to 16 years with high levels of response to ACR criteria. No new safety signals were identified for the well-characterized components of this fixed dosed JIA treatment, which was developed to reduce the risk of gastric ulcers.Clinicaltrials.gov, NCT01544114 .
