ABSTRACT

BACKGROUND: Osteoarthritis (OA) is a leading cause of disability in the United States. Although no disease-modifying therapies exist, patients with knee OA who increase walking may reduce risk of functional limitations. OBJECTIVE: The objective of the study is to evaluate the impact of a mobile app (OA GO) plus wearable activity monitor/pedometer (Jawbone UP 24) used for 90 days on the mobility of patients with knee OA treated with hylan G-F 20. METHODS: Patients with knee OA aged 30 to 80 years who were eligible to receive hylan G-F 20 and were familiar with smartphone technology were enrolled in this randomized, multicenter, open-label study. Patients who had a body mass index above 35 kg/m2 were excluded. All patients received a single 6-mL injection of hylan G-F 20 and wore the Jawbone monitor. The patients were then randomized 1:1 to Jawbone and OA GO (Group A; n=107) with visible feedback (unblinded) or Jawbone only (Group B; n=104) with no visible feedback (blinded). The primary endpoint was mean change from baseline in steps per day at day 90 between Groups A and B. RESULTS: Baseline characteristics were similar between groups. There were significant differences between the increases in least squares (LS) mean number of steps per day (1199 vs 467, P=.03) and the mean percentage change (35.8% vs 11.5%, P=.02) from baseline in favor of Group A over Group B. There was a greater reduction in pain from baseline during the 6-minute walk test in Group A versus Group B. (LS mean change: -55.3 vs -33.8, P=.007). Most patients (65.4%) and surveys of physicians (67.3%) reported they would be likely or very likely to use/recommend the devices. Patient Activity Measure-13 scores improved from baseline (LS mean change for Groups A and B: 5.0 vs 6.9), with no significant differences between groups. The occurrence of adverse events was similar in the 2 groups. CONCLUSIONS: Use of a novel smartphone app in conjunction with a wearable activity monitor provided additional improvement on mobility parameters such as steps per day and pain with walking in the 6-minute walk test in patients with knee OA who were treated with hylan G-F 20. Results also highlight the amenability of patients and physicians to using mobile health technology in the treatment of OA and suggest further study is warranted.

ABSTRACT

BACKGROUND: Pneumococcal disease remains an important health priority despite successful implementation of pneumococcal conjugate vaccines (PCVs) in infant immunization programs, mainly due to the emergence of diseases caused by serotypes not included in licensed PCVs. A 15-valent pneumococcal conjugate vaccine (PCV-15) containing the 7 serotypes (4, 6B, 9V, 14, 18C, 19F, and 23F) included in licensed PCV-7 available at study initiation plus 8 additional serotypes (1, 3, 5, 6A, 7F, 19A, 22F, 33F) was developed and evaluated in healthy adults 18-45 years of age. METHODS: Sixty subjects received one dose of PCV-15 or PCV-7. Injection-site and systemic adverse events (AEs) were collected for 14-days postvaccination and serious AEs were collected for 30-days postvaccination. Safety laboratory tests (hematology, chemistry, and urinalysis) were evaluated prior to vaccination and 14-days postvaccination. Serotype-specific IgG and opsonophagocytic killing activity (OPA) responses to 15 serotypes included in PCV-15 were measured immediately prior to vaccination and 30-days postvaccination. RESULTS: AE incidences were comparable between vaccine groups although numerically higher frequencies of erythema (33.3% versus 13.3%), swelling (50.0% versus 23.3%), and myalgia (63.3% versus 36.7%) were reported among PCV-15 versus PCV-7 recipients. Majority of AEs, irrespective of vaccine received, were transient and of mild-to-moderate intensity. No clinically significant differences were observed when comparing AE duration and severity. No laboratory abnormalities, vaccine-related SAEs or discontinuations from the study due to AEs were reported. IgG concentrations for the shared serotypes substantially increased postvaccination at comparable levels between recipients of PCV-15 and PCV-7. Substantial increases in antibody (IgG and OPA) responses to 8 serotypes unique to PCV-15 were observed in PCV-15 recipients. Slight increases to 2 serotypes unique to PCV-15, serotypes 6A and 19A, were also noted in PCV-7 recipients. CONCLUSION: PCV-15 displays an acceptable safety profile and induces IgG and OPA responses to all serotypes included in the vaccine.

ABSTRACT

OBJECTIVE: To evaluate the efficacy and safety of taspoglutide monotherapy in drug-naive patients with type 2 diabetes inadequately controlled. RESEARCH DESIGN AND METHODS: In this 24-week double-blind, placebo-controlled, multicenter trial, 373 patients with type 2 diabetes naive to antihyperglycemic medication were randomized to weekly subcutaneous taspoglutide 10 or 20 mg or placebo. RESULTS: HbA(1c) reductions from baseline were greater with taspoglutide 10 and 20 mg than placebo (least squares mean [SE] changes: -1.01% [0.07], -1.18% [0.06], and -0.09% [0.07], respectively; both P < 0.0001 vs. placebo). Decreases in bodyweight were greater with taspoglutide 10 mg (-1.45 kg [0.32]) and with 20 mg (-2.25 kg [0.30]) than placebo (-1.23 kg [0.31]; P = 0.61 and P = 0.02 for taspoglutide 10 and 20 mg vs. placebo, respectively). Gastrointestinal adverse events and injection site reactions were more common with taspoglutide than placebo. CONCLUSIONS: In drug-naive patients, once-weekly taspoglutide improved glycemic control, reduced body weight, and was generally well tolerated.

ABSTRACT

Scientists are seeking ways to increase high-density lipoprotein (HDL) cholesterol to lower coronary heart disease (CHD). Emerging from this search is torcetrapib, a partial inhibitor of cholesteryl ester transfer protein. Via this mechanism, cholesteryl ester is prevented from being transferred to apolipoprotein B-containing lipoproteins and is retained in HDL particles, where ostensibly it may be delivered directly to the liver for elimination. Proof that this may reduce atherosclerotic vascular disease is provided by population studies of cholesteryl ester transfer protein (CETP) deficiencies and single nucleotide polymorphisms of CETP, and experiments in animal models treated with torcetrapib. Torcetrapib effectively raises HDL cholesterol when used alone and when added to background therapy with atorvastatin. The drug appears to be well tolerated. Large surrogate and survival outcome trials are underway to document its impact on CHD.
