Cardiorenal outcomes, kidney function, and other safety outcomes with ertugliflozin in older adults with type 2 diabetes (VERTIS CV): secondary analyses from a randomised, double-blind trial.

BACKGROUND: VERTIS CV was a randomised, double-blind, placebo-controlled, parallel-group, multicentre cardiovascular outcomes trial that evaluated the cardiovascular efficacy and safety of ertugliflozin in adults with type 2 diabetes and atherosclerotic cardiovascular disease. The primary objective of VERTIS CV was to show non-inferiority of ertugliflozin to placebo with respect to the primary outcome, major adverse cardiovascular events (a composite of death from cardiovascular causes, non-fatal myocardial infarction, or non-fatal stroke). The analyses reported here aimed to assess cardiorenal outcomes, kidney function, and other safety outcomes with ertugliflozin in older adults with type 2 diabetes and atherosclerotic cardiovascular disease compared with younger participants. METHODS: VERTIS CV was done at 567 centres in 34 countries. Participants (aged ≥40 years) with type 2 diabetes and atherosclerotic cardiovascular disease were randomly assigned (1:1:1) to once-daily ertugliflozin 5 mg, ertugliflozin 15 mg, or placebo in addition to background standard-of-care treatment. Random assignment was done with the use of an interactive voice-response system. The study outcomes were major adverse cardiovascular events, hospitalisation for heart failure or cardiovascular death, cardiovascular death, hospitalisation for heart failure, prespecified kidney composite outcomes, kidney function, and other assessments of safety. Cardiorenal outcomes, kidney function, and safety outcomes were evaluated by baseline age (≥65 years and <65 years [prespecified] and ≥75 years and <75 years [post hoc]). The study is registered with ClinicalTrials.gov, NCT01986881. FINDINGS: Between Dec 13, 2013, and July 31, 2015, and between June 1, 2016, and April 14, 2017, 8246 adults with type 2 diabetes and atherosclerotic cardiovascular disease were recruited to the study and randomly assigned. 2752 patients were assigned to ertugliflozin 5 mg, 2747 patients to ertugliflozin 15 mg, and 2747 patients to placebo. 8238 participants received at least one dose of ertugliflozin 5 mg, ertugliflozin 15 mg, or placebo. 4145 (50·3%) of 8238 participants were aged 65 years and older, including 903 (11·0%) participants aged 75 years and older. 5764 (70·0%) of 8238 participants were male and 2474 (30·0%) were female, and 7233 (87·8%) of 8238 participants were White, 497 (6·0%) were Asian, 235 (2·9%) were Black, and 273 (3·3%) were classified as other. The mean estimated glomerular filtration rate (eGFR) was lower and the type 2 diabetes duration longer for those aged 65 years and older versus those younger than 65 years, and for those aged 75 years and older versus those younger than 75 years. Cardiovascular outcomes were more common in the older age subgroups than in the younger age subgroups. Similar to the overall VERTIS CV cohort, ertugliflozin did not increase the risk of major adverse cardiovascular events, cardiovascular death or hospitalisation for heart failure, cardiovascular death alone, or the kidney composite outcome (using doubling of serum creatinine, dialysis or transplantation, or kidney death), and reduced the risk of hospitalisation for heart failure and the exploratory kidney composite outcome (using a 40% sustained eGFR decrease, dialysis or transplantation, or kidney death) in the older age subgroups (pinteraction>0·05 for outcomes assessed). A slower decline in eGFR and a smaller increase in the urine albumin-to-creatinine ratio were observed over time in all age subgroups taking ertugliflozin compared with placebo. Across age subgroups, safety outcomes were consistent with the known profile of ertugliflozin. INTERPRETATION: The effects of ertugliflozin on cardiorenal outcomes, kidney function, and safety outcomes were generally similar across age subgroups. These results have the potential to help clinical decision making by providing a longer-term evaluation of the cardiorenal safety and overall tolerability of ertugliflozin in a large population of older adults.

Multi-Criteria Decision Analysis to Develop an Efficacy-Safety Profile of Parenteral Analgesics Used in the Treatment of Postoperative Pain.

BACKGROUND: Identifying the optimal treatment in an acute postoperative setting remains a challenge. Multiple analgesic options are available, but comparing outcomes is limited by a lack of head-to-head trials. In addition, decisions based on efficacy only do not take drug safety into account. In such cases, multi-criteria decision analysis (MCDA) can be utilized to quantify and compare the efficacy and safety data of various drugs. METHODOLOGY: The efficacy-safety profiles of eight parenteral, postoperative analgesics (acetaminophen, diclofenac, ketorolac, metamizole, morphine, nefopam, parecoxib, tramadol) widely used in Europe were evaluated using an MCDA model that included 17 criteria: three for efficacy and 14 for safety. Each drug was scored on each criterion on a scale from 0 (worst) to 100 (best), according to published data and the judgment of an expert panel. A weighting process was then applied to standardize the impact of each criterion and adjust drugs' preference scores accordingly, normalizing them on the 0-100 scale. Sensitivity analyses were also performed, including a model in which analgesic profiles were compared when opioid sparing effect was set at a zero value for all drugs. RESULTS: In the primary model, efficacy and safety had relative weightings of 64% and 36%, respectively. Efficacy and safety criteria with the highest values were pain relief (relative weight, 29%) and gastrointestinal effects (12%). Parecoxib received the highest overall score (93), followed by diclofenac (80), and ketorolac (75). Morphine scored the lowest (57), due to the lack of an opioid sparing effect. When opioid sparing was given a zero rating, parecoxib remained the highest scoring analgesic (93), followed by diclofenac (80), metamizole (76), and morphine (76). Parecoxib remained the most preferred analgesic in several other sensitivity analyses. CONCLUSION: This MCDA-based assessment suggests that parecoxib has the most favorable efficacy-safety profile among the assessed postoperative analgesics.

The relationship between postoperative opioid consumption and the incidence of hypoxemic events following total hip arthroplasty: a post hoc analysis.

Background: Postoperative opioid analgesia may cause respiratory depression. We assessed whether following total hip arthroplasty, placebo-adjusted reductions in morphine consumption at 48 hours with parecoxib (47.0%), propacetamol (35.1%) or parecoxib plus propacetamol (67.9%) translated into a reduction in hypoxemic events. Methods: This was a post hoc analysis of a randomized, placebo-controlled, noninferiority study. Patients were randomly assigned to receive intravenous parecoxib (40 mg twice daily), propacetamol (2 g 4 times daily), parecoxib plus propacetamol (40 mg twice daily + 2 g 4 times daily) or placebo. Dose, date and time of morphine administration via patient-controlled analgesia were monitored throughout the study. In patients not receiving supplemental oxygen, peripheral blood oxygenation was assessed continuously for 48 hours after surgery. Hypoxemia was defined as peripheral oxygen saturation less than 90%. The times and oximeter readings of hypoxemic events were recorded. Pearson correlation coefficient was used to assess for correlations between cumulative morphine consumption at 48 hours and mean number of hypoxemic events. Results: A significantly smaller proportion of patients who received the combined treatment with parecoxib and propacetamol had hypoxemia versus placebo (2.8% v. 13.2%, p < 0.05), and the mean number of hypoxemic events was significantly smaller for parecoxib (0.12), propacetamol (0.06) and parecoxib plus propacetamol (0.03) versus placebo (0.36; all p < 0.05). There was no correlation between the reduction in cumulative morphine consumption at 48 hours and the mean number of hypoxemic events in any treatment group (all p > 0.1). Conclusion: Following total hip arthroplasty, a greater than 70% reduction in morphine consumption may be necessary to translate into a corresponding reduction in hypoxemic events.

Contexte: L'utilisation d'analgésiques opioïdes en période postopératoire peut provoquer une dépression respiratoire. Nous avons voulu déterminer si, après une arthroplastie totale de la hanche, une réduction de la consommation de morphine à 48 heures par l'administration de parécoxib (47,0 %), de propacétamol (35,1 %) ou d'une combinaison des deux (67,9 %) ­ avec ajustement selon un groupe placebo ­ se traduirait par une réduction du nombre d'épisodes d'hypoxémie. Méthodes: Nous avons effectué une analyse post hoc d'une étude randomisée de non-infériorité avec témoins sous placebo. Après une répartition aléatoire, chaque patient a reçu par intraveineuse du parécoxib (40 mg 2 fois par jour), du propacétamol (2 g 4 fois par jour), une combinaison de parécoxib et de propacétamol (40 mg 2 fois par jour + 2 g 4 fois par jour) ou un placebo. Tout au long de l'étude, la dose, la date et le moment de l'administration de morphine contrôlée par le patient ont été notés. Chez les patients qui ne recevaient pas d'oxygène d'appoint, la saturation périphérique en oxygène a été surveillée de manière continue pendant les 48 heures suivant l'opération. L'hypoxémie a été définie comme une saturation inférieure à 90 %. Le moment et les données d'oxymétrie ont été notés pour chaque épisode d'hypoxémie. Le coefficient de corrélation de Pearson a été utilisé pour évaluer la présence de corrélations entre la consommation cumulative de morphine durant les premières 48 heures et le nombre moyen d'épisodes d'hypoxémie. Résultats: Une proportion significativement plus faible de patients ayant reçu le traitement combiné de parécoxib et de propacétamol ont connu des épisodes d'hypoxémie, comparativement aux patients qui avaient reçu le placebo (2,8 % c. 13,2 %, p < 0,05), et le nombre moyen d'épisodes d'hypoxémie était significativement plus faible dans le groupe ayant reçu du parécoxib (0,12), du propacétamol (0,06) ou une combinaison de parécoxib et de propacétamol (0,03), par rapport au groupe placebo (0,36, p < 0,05 pour tous). Aucune corrélation n'a été observée entre la réduction de la quantité totale de morphine consommée à 48 heures et le nombre moyen d'épisodes d'hypoxémie pour tous les groupes (p > 0,1 pour tous). Conclusion: Après une arthroplastie totale de la hanche, une réduction de la consommation de morphine de plus de 70 % pourrait être nécessaire pour obtenir une réduction correspondante du nombre d'épisodes d'hypoxémie.

Reframing chronic pain as a disease, not a symptom: rationale and implications for pain management.

Chronic pain is a common public health problem that has a detrimental impact on patient health, quality of life (QoL), and function, and poses a substantial socioeconomic burden. Evidence supports the redefinition of chronic pain as a distinct disease entity, not simply a symptom of injury or illness. Chronic pain conditions are characterized by three types of pain pathophysiology (i.e. nociceptive, neuropathic, and centralized pain/central sensitization) influenced by a cluster of coexisting psychosocial factors. Negative risk/vulnerability factors (e.g. mood or sleep disturbances) and positive resilience/protective factors (e.g. social/interpersonal relationships and active coping) interact with pain neurobiology to determine patients' unique pain experience. Viewing chronic pain through a biopsychosocial lens, instead of a purely biomedical one, clinicians need to adopt a practical integrated management approach. Thorough assessment focuses on the whole patient (not just the pain), including comorbidities, cognitive/emotional/behavioral characteristics, social environment, and QoL/functional impairment. As for other complex chronic illnesses, the treatment plan for chronic pain can be developed based on pain subtype and psychosocial profile, incorporating pharmacotherapy and self-management modalities. Preferred pharmacologic treatment of conditions primarily associated with nociception (e.g. osteoarthritis) includes acetaminophen and non-steroidal anti-inflammatory drugs, whereas preferred pharmacologic treatment of conditions primarily associated with neuropathy or central sensitization (e.g. fibromyalgia) includes tricyclic compounds, serotonin-norepinephrine reuptake inhibitors, and α2δ ligands. Education, exercise, cognitive behavioral therapy, and many other non-pharmacological approaches, alone or combined with pharmacotherapy, have been shown to be effective for any type of pain, although they remain underutilized due to lack of awareness of their benefits and reimbursement obstacles.

Factors Related to the Use of Topical vs. Oral NSAIDs for Sprains, Strains, and Contusions in a Senior Population: A Retrospective Analysis of Administrative Claims Data.

BACKGROUND: Research to date on sprains, strains, and contusions has focused mainly on the analysis of sports-related injuries, occupational injuries, injuries resulting from automobile accidents, and severe injuries that result in inpatient hospital stays. Little is known about real-world acute sprains, strains, and contusions in an aging population. Patients may be treated with over-the-counter, oral, non-steroidal anti-inflammatory drugs (NSAIDs) for acute sprains, strains, and contusions or may require the use of prescription NSAIDs. For sprains, strains, and contusions treated with prescription NSAIDs, the choice of topical administration or oral administration likely depends on a number of factors such as age and comorbid conditions. OBJECTIVES: The objective of the study was to identify factors associated with the use of a prescription topical NSAID or a prescription oral NSAID for the treatment of sprains, strains, and contusions among patients aged 65-89 years enrolled in the Medicare Advantage with Prescription Drug plan. METHODS: The study sample was selected from the Humana Research Database (Louisville, KY, USA). Study subjects were identified as patients enrolled in Medicare Advantage with Prescription Drug plans, aged 65-89 years, having a medical claim with an International Classification of Diseases, Ninth Revision, Clinical Modification indicative of an acute sprain, strain, and contusion between 1 January, 2010 and 31 March, 2014 (identification period). The date of the first claim was considered the index date, and subjects were required to have 12 months of continuous enrollment before the index date and a minimum of 3 months continuous enrollment after the index date. Prescription NSAID use during the 3 months after the index sprain, strain, and contusion diagnosis was required for study inclusion and was identified based on a pharmacy claim for a topical or an oral NSAID. Patients with prescription NSAID use leading up to the sprains, strains, and contusions were excluded. Potential factors related to the use of a topical vs. oral NSAID were identified using stepwise logistic regression with backward elimination. RESULTS: After applying the inclusion and exclusion criteria, 42,283 patients were prescribed an oral or topical NSAID (39,294 oral; 2989 topical) within 3 months of the index sprain, strain, and contusion diagnosis. After applying stepwise logistic regression, and retaining variables with statistically significant parameter estimates (p < 0.05), use of topical NSAIDs was higher among female individuals [odds ratio and 95% confidence interval = 1.34 (1.24-1.45)], and appeared to increase with age [odds ratio = 1.04 (1.04-1.05)]. Topical NSAID use was lower in the Midwest region [odds ratio = 0.85 (0.77-0.94)] in comparison to the Southern region. Clinical factors associated with topical NSAID use included Elixhauser Comorbidity Index score [odds ratio = 1.06 (1.04-1.09)], medication burden [odds ratio = 1.06 (1.04-1.08), pill burden [odds ratio = 1.02 (1.01-1.03), specific comorbid conditions, including site-specific osteoarthritis of the upper arm [odds ratio = 2.34 (1.19-4.60)], ankle/foot [odds ratio = 1.46 (1.14-1.87)], or lower leg [odds ratio = 1.21 (1.07-1.36)], myofascial pain [odds ratio = 1.31 (1.21-1.42)], gastrointestinal/hepatic disorders [odds ratio = 1.15 (1.05-1.25)], systemic/central pain [odds ratio = 1.12 (1.01-1.23)], and cataracts [odds ratio = 1.10 (1.02-1.20)]. Conversely, a diagnosis of diabetes mellitus was related to use of an oral NSAID rather than a topical NSAID [odds ratio = 0.86 (0.78-0.94)]. Diagnosis of the index sprain, strain, and contusion in an emergency department instead of a physician's office was also associated with oral NSAID use [odds ratio = 0.42 (0.37-0.47)]. CONCLUSIONS: Topical NSAIDs were used less often than oral NSAIDs following a sprain, strain, or contusion. Age, medication burden, pill burden, evidence of gastrointestinal disorder, and evidence of certain pain-related conditions were significant factors associated with topical NSAID as opposed to oral NSAID use. In comparison to oral NSAIDs, topical NSAIDs were more likely to be prescribed in a physician's office than an emergency department, possibly because a patient's physician has a better understanding of the patient's concomitant medications and comorbidities. Although topical NSAIDs were more likely to be used than oral NSAIDs in patients with gastrointestinal disorders, the use of oral NSAIDs among patients with gastrointestinal bleeding was substantial.

A randomized study of the efficacy and safety of parecoxib for the treatment of pain following total knee arthroplasty in Korean patients.

PURPOSE: Parecoxib is an injectable cyclooxygenase-2 inhibitor with proven postoperative analgesic efficacy in a variety of settings, including total knee arthroplasty (TKA). The effect of ethnicity on the efficacy of parecoxib for post-TKA pain has not been studied. PATIENTS AND METHODS: This was a parallel-group, double-blind, randomized, placebo- controlled study of ethnically Korean patients aged ≥18 years who had unilateral TKA. Patients who reported moderate or severe pain 6 hours after the end of postoperative opioid analgesia were randomized to receive a single intravenous dose of parecoxib sodium 40 mg or placebo. Patients were evaluated for 24 hours postdose. The primary efficacy endpoints included time-specific pain intensity difference (PID), time-specific pain relief (PR), and time to rescue medication. The incidence and nature of adverse events (AEs) assessed safety. RESULTS: Of the 116 patients randomized, 58 received parecoxib and 58 placebo. Mean (SD) PID was significantly greater for parecoxib vs placebo 1 hour postdose (0.69 [0.67] vs 0.40 [0.59], respectively; p<0.05), and for each time point up to 24 hours. Similarly, mean (SD) PR was significantly greater for parecoxib vs placebo 1.5 hours postdose (1.63 [0.85] vs 1.07 [0.90], respectively; p=0.001), and for each time point up to 24 hours. The median time (hours:minutes) to rescue medication was significantly longer for parecoxib vs placebo (21:30 vs 4:08, respectively; p<0.001). Generally, fewer AEs were reported with parecoxib than placebo, and the AE profile was consistent with previous studies. These results are comparable to the findings from a similarly designed study in a Caucasian patient population. CONCLUSION: Parecoxib 40 mg significantly improved postoperative pain vs placebo in Korean patients after TKA. The efficacy and safety of parecoxib in Korean patients is similar to that seen in Caucasian patients.

Parecoxib relieves pain and has an opioid-sparing effect following major gastrointestinal surgery.

PURPOSE: Parecoxib provides analgesia following a variety of surgeries, including minor gastrointestinal procedures. To our knowledge, there is no data on parecoxib following major gastrointestinal surgery. This study assessed the efficacy and opioid-sparing effects of parecoxib following major gastrointestinal surgeries. PATIENTS AND METHODS: Patients in this analysis were a subset from a large, randomized, double-blind, placebo-controlled trial of parecoxib following noncardiac surgeries and consisted of those undergoing a variety of major gastrointestinal surgeries via laparotomy. Pain, pain interference with function, supplemental opioid utilization, opioid-related symptoms, and Patient/Physician Global Evaluation of Study Medication were compared between placebo and parecoxib groups in the 2-3 days following surgery. RESULTS: Significantly (p<0.001) lower pain scores were observed in the parecoxib group (n=111), relative to placebo (n=126), on Day 2 (-33%) and Day 3 (-35%). Pain interference with function scores was also significantly (p<0.001) lower among patients receiving parecoxib compared with placebo on Day 2 (-29%) and Day 3 (-36%). At 24, 48, and 72 hours, the cumulative amount of supplemental morphine consumed was 45%, 41%, and 40% less in patients receiving parecoxib compared with placebo (all p<0.001). The risk of experiencing ≥1 opioid-related symptoms was also significantly lower with parecoxib than with placebo on Day 2 (relative risk=0.75; p<0.001). Specifically, the risks of fatigue and drowsiness were significantly (both p<0.05) lower in patients receiving parecoxib compared to those receiving placebo. Patient and Physician Global Evaluation of Study Medication scores were significantly better in the parecoxib group than in the placebo group (p<0.001). CONCLUSION: This study is the first to demonstrate that multiple-dose parecoxib, initiated upon recovery from anesthesia, provides analgesia and opioid-sparing effects following a variety of major gastrointestinal surgeries employing laparotomy.

Children's International Polyposis (CHIP) study: a randomized, double-blind, placebo-controlled study of celecoxib in children with familial adenomatous polyposis.

OBJECTIVE: To evaluate the efficacy and safety of celecoxib versus placebo in the prevention and treatment of colorectal polyposis in children with familial adenomatous polyposis (FAP). METHODS: In this Phase III, double-blind, randomized, placebo-controlled, multicenter trial patients aged 10-17 years with FAP were randomized to celecoxib (16 mg/kg/day) or placebo for up to 5 years. Patients underwent annual assessments, including colonoscopies, to detect the time from randomization to the earliest occurrence of ≥20 polyps (>2 mm in size) or colorectal malignancy. The study was terminated early due to low rate of observed endpoints combined with a lower than expected enrollment rate. Descriptive results are provided. RESULTS: Of 106 randomized patients, 55 were treated with celecoxib (mean age 12.6 years; 52.7% female) and 51 were given placebo (mean age 12.2 years; 54.9% female). Disease progression (≥20 polyps, >2 mm in size) was observed in seven (12.7%) and 13 (25.5%) patients, respectively. The median time to disease progression was 2.1 years in the celecoxib group and 1.1 years for placebo. No patient developed colorectal cancer. The rate of adverse events (AEs) was similar in both groups (75.5% and 72.9%, respectively). Three patients in the celecoxib group (none in the placebo group) experienced serious AEs. CONCLUSION: In children with FAP, celecoxib was a well-tolerated treatment that was associated with a lower rate of colorectal polyposis and a longer time to disease progression compared with placebo. Due to the low rate of observed endpoints, the long-term impact of these results could not be ascertained.

Safety of parecoxib when used for more than 3 days for the management of postoperative pain.

AIM: To assess parecoxib safety when used for >3 days for postoperative pain management. METHODS: Treatment-emergent adverse event (TEAE) occurrence after day 3 was examined in a pooled analysis of three placebo-controlled trials of parecoxib following general or gynecologic surgery, or total hip arthroplasty. A total of 358 patients received parecoxib, and 318 placebo. RESULTS: Mean treatment duration was similar between treatment groups. The overall frequency of all TEAEs after day 3 was also similar between treatment groups. Most TEAEs occurred in <1% of patients after day 3; frequencies were similar between treatment groups. Most TEAEs were considered mild or moderate in severity. CONCLUSION: TEAE occurrence in patients receiving parecoxib for >3 days was low and similar to placebo after treatment day 3.

Evaluation of the Relationship Between Serum Uric Acid Levels and Cardiovascular Events in Patients With Gout: A Retrospective Analysis Using Electronic Medical Record Data.

OBJECTIVES: The aim of this study was to evaluate relationships between serum uric acid (SUA) and newly emergent acute myocardial infarction (AMI), congestive heart failure (CHF), coronary artery disease (CAD), composite cardiovascular (CV) events (AMI, CHF, CAD), hypertension, hyperlipidemia, and renal disease in gout patients. METHODS: Retrospective analysis of electronic medical records from Humedica identified adults (≥18 years) with 2 or more International Classification of Diseases, Ninth Revision, Clinical Modification codes for gout 30 days or more apart (first diagnosis = index event) having 1 or more SUA assessment on or after the index date, and at least 6 months preindex and at least 12 months postindex enrollment. Outcomes were measured during 12 months postindex; patients with preindex events were excluded from analysis of those events. The SUA level (0.01-4.00 mg/dL, 4.01-6.00 mg/dL, 6.01-8.00 mg/dL, and ≥8.01 mg/dL) was determined using the closest laboratory assessment before or on the date of the CV event. Tukey-Kramer comparisons were performed for pairs of SUA strata and Cox proportional model estimated hazard ratios. RESULTS: A significantly higher incidence of AMI, CHF, and renal disease was observed for patients with 8.01 mg/dL or greater relative to other SUA levels (P < 0.0001), and a significantly higher incidence of composite CV events (AMI, CHF, and CAD) was observed for hypouricemia (SUA, 0.01-4.00 mg/dL) compared with other SUA levels (P < 0.0001). Cox models confirmed the increased risk associated with SUA 8.01 mg/dL or greater; hazard ratios ranged from 1.16 for hypertension to 2.04 for renal disease. Hyperlipidemia and hypertension were diagnosed concurrently with gout in 24% and 28% of patients, respectively. CONCLUSIONS: Hyperuricemia and hypouricemia were associated with an increased risk of CV events.

Parecoxib Provides Analgesic and Opioid-Sparing Effects Following Major Orthopedic Surgery: A Subset Analysis of a Randomized, Placebo-Controlled Clinical Trial.

INTRODUCTION: Orthopedic surgeries are among the most common and most painful surgeries performed. A multimodal analgesic approach is recommended to reduce opioid consumption, provide effective pain relief, and improve outcomes following surgery. This study examined the efficacy and opioid-sparing effects of parecoxib following major orthopedic surgery. METHODS: This subset analysis of a large, multicenter, randomized, double-blind, placebo-controlled study of parecoxib examined treatment effects on postoperative pain severity, pain interference with function, opioid consumption, occurrence of opioid-related symptoms, safety, and patient satisfaction following major orthopedic surgery. RESULTS: Pain scores were significantly lower in the parecoxib group (n = 142) compared with placebo (n = 139) on day 2 (-22%; p < 0.001) and day 3 (-17%; p = 0.004). Pain interference with function scores were also significantly lower in the parecoxib group on day 2 (-32%; p < 0.001) and day 3 (-27%; p = 0.003) relative to placebo. Additionally, significantly less supplemental morphine was required in the parecoxib group relative to placebo through 24 h (-28%; p = 0.008) and 48 h (-33%; p < 0.001). Patients in the parecoxib group had a reduced risk of experiencing opioid-related symptoms including fatigue, drowsiness, inability to concentrate, confusion, nausea, constipation, and confusion on day 2 and/or day 3. Finally, more patients receiving parecoxib (42%) rated treatment as "excellent" compared to those receiving placebo (21%). CONCLUSIONS: These findings support the use of parecoxib for the management of pain following major orthopedic surgery.

Efficacy and tolerability of celecoxib and naproxen versus placebo in Hispanic patients with knee osteoarthritis.

BACKGROUND: Celecoxib is an effective treatment for osteoarthritis (OA). However, information on its efficacy and safety profile in different racial/ethnic groups is limited. Noticeable differences among racial groups are found in other disease states, but a thorough investigation of OA is lacking. The objective of this study was to determine if celecoxib 200 mg once daily is as effective as naproxen 500 mg twice daily in the treatment of OA of the knee in Hispanic patients. METHODS: Hispanic patients aged ≥45 years with knee OA were randomized to receive celecoxib 200 mg once daily, naproxen 500 mg twice daily, or placebo for 6 weeks. The primary efficacy variable was the change in Patient's Assessment of Arthritis Pain at 6 weeks compared with baseline. Secondary variables were change in Patient's and Physician's Global Assessments of Arthritis from baseline to week 6/early termination, change in Western Ontario and McMaster Universities OA Index (WOMAC) from baseline to week 6/early termination, change in American Pain Society pain score, Pain Satisfaction Scale, Patient Health Questionnaire (PHQ-9), and measurements of upper gastrointestinal tolerability. RESULTS: In total, 239 patients completed the trial (96 celecoxib, 96 naproxen, 47 placebo). Celecoxib was as effective as naproxen in reducing OA pain (least squares mean change from baseline [standard error] -39.7 [2.7] for celecoxib and -36.9 [2.6] for naproxen). Patient's and Physician's Global Assessments of Arthritis, WOMAC scores, upper gastrointestinal tolerability, Pain Satisfaction Scale, and PHQ-9 showed no statistically significant differences between the celecoxib and naproxen groups. The incidence of adverse events and treatment-related adverse events were similar among the treatment groups. CONCLUSION: Celecoxib 200 mg once daily was as effective as naproxen 500 mg twice daily in the treatment of signs and symptoms of knee OA in Hispanic patients. Celecoxib was shown to be safe and well tolerated in this patient population.

The Efficacy of Continuous Versus Intermittent Celecoxib Treatment in Osteoarthritis Patients with Body Mass Index ≥30 and <30 kg/m(2.).

OBJECTIVE: Characterize the effect of body mass index (BMI) on the efficacy of continuous daily celecoxib treatment compared with intermittent celecoxib treatment. METHODS: Prespecified exploratory analysis of a 24-week, double-blind, parallel-group, randomized, multicenter international study. 858 patients with knee or hip osteoarthritis (OA) were randomized to receive celecoxib 200 mg daily either as continuous or intermittent treatment. Efficacy was measured by Western Ontario and McMaster Universities Arthritis Index (WOMAC) total and subscale scores and the number of flare events. RESULTS: Least squares mean increases (worsening) in WOMAC total scores were significantly less in the continuous treatment group than in the intermittent treatment group in patients with a BMI <30 kg/m(2) (1.33 vs 4.85; p=0.016) and in patients with a BMI ≥30 kg/m(2) (1.84 vs 5.12; p=0.019). There was a greater worsening in patients with a BMI ≥30 kg/m(2) than in those with a BMI <30 kg/m(2) in both the continuous and intermittent groups. Fewer flares were reported in the continuous treatment group than in the intermittent group in patients with a BMI <30 kg/m(2) (0.55 vs 0.88; p<0.0001) and ≥30 kg/m(2) (0.54 vs 0.97; p<0.0001). There were no differences in adverse events in the two BMI groups. CONCLUSIONS: Continuous celecoxib treatment was significantly more efficacious than intermittent use in patients with a BMI <30 kg/m(2) compared with obese patients (≥30 kg/m(2)) as assessed by WOMAC total scores and the number of flares. These data suggest that including weight loss as part of a treatment regimen for obese OA patients could be important.

Prevalence of gastroprotective agent (GPA) use in adults with arthritis in the United States.

OBJECTIVE: The prevalence of non-steroidal anti-inflammatory drug (NSAID) and concurrent gastroprotective agent (GPA) use in the US is not known. As such, the prevalence of GPA use among arthritis patients taking NSAIDs was examined. METHODS: Men and women aged ≥ 40 with self-reported arthritis and members of a web-based community panel were invited via e-mail to participate in a web survey. Interested panelists consented and completed the survey. Participants using NSAIDs in the last 30 days were eligible. Questions regarding NSAID and GPA use were asked, likewise adherence to GPA (Morisky scale), comorbid conditions, gastrointestinal (GI) history, and other risk factors. Descriptive analyses and logistic regressions were performed to assess associations with GPA use and adherence. RESULTS: Invitations were sent to 7605 adults; 4108 (54%) responded; 2208 completed. Final sample was 1525 (76%) with osteoarthritis (OA), 354 (18%) with rheumatoid arthritis (RA), and 121 (6%) with both OA and RA. Mean age was 62.0; 64% were female; 83% white; 25% worked full-time, and 39% were retired. Mean duration with arthritis was 13.0 years; 47% and 19% experienced arthritis symptoms 'daily' and 'almost always', respectively. Nearly 43% reported using a GPA and 39% of daily NSAID users reported taking a GPA. Fifty-eight participants (2.9%) were classified as low GI risk, 342 (17.1%) were moderate risk, and 1600 (80.0%) were high risk. Variables significantly associated with GPA use included older age; male gender; being white (vs. Hispanic); taking an NSAID at least daily; taking fewer NSAIDs; taking a Cox-2 inhibitor or prescription NSAID; history of GI conditions; prescription antiplatelet use; and having GI symptoms. Similar variables were associated with GPA adherence. CONCLUSION: Less than half of adult men and women in the US taking a daily NSAID used GPAs and only 37% of high-risk participants were taking GPAs.

Safety of celecoxib compared with placebo and non-selective NSAIDs: cumulative meta-analysis of 89 randomized controlled trials.

OBJECTIVE: Further understand the safety profile of celecoxib and provide safety information for important adverse events (AEs). METHODS: Analysis of randomized controlled trials from the Pfizer clinical trial repository (final study reports completed by 31 July 2011) in which celecoxib was compared with placebo or non-selective non-steroidal anti-inflammatory drugs (nsNSAIDs) for treatment of pain or inflammation in adults. Safety end points comprised 18 terms that had been identified as important AEs among all NSAIDs. RESULTS: There was a greater risk of edema (risk difference (95% confidence interval) 0.77% (0.45, 1.09)); hypertension (0.28% (-0.01, 0.57)); angioedema (0.16% (-0.06, 0.39) and allergic reactions (0.15% (-0.10, 0.40)) with celecoxib than with placebo, while a greater risk of gastrointestinal (GI) hemorrhage (-0.15% (-0.47, 0.16)) was seen with placebo. There was a greater risk of GI hemorrhage (-0.53% (-0.72, -0.33)), GI ulceration (-0.46% (-0.60, -0.33)), edema (-0.62% (-0.89, -0.35)) and hypertension (-0.57% (-0.82, -0.33)) with nsNSAIDs than with celecoxib. CONCLUSIONS: The magnitude of risks associated with NSAIDs is small and similar in celecoxib-, nsNSAID- and placebo-treated patients. This analysis provides safety information that will allow physicians to make informed treatment decisions for patients who are appropriate candidates for celecoxib use.
