Osteoarthritis (OA) is a progressive and degenerative disease, which may result in significant pain and decreased quality of life. Recent updates in our understanding of OA have demonstrated that it is a whole joint disease that has many similarities to an unhealed wound containing inflammatory cytokines. The nSTRIDE Autologous Protein Solution (APS) Kit is a medical device under development for the treatment of OA. The APS Kit processes a patient's own blood at the point of care to contain high concentrations of anti-inflammatory cytokines and anabolic growth factors. This study assessed the safety and treatment effects of a single intra-articular injection of APS. Eleven patients were enrolled in this study. Sufficient blood could not be drawn from one patient who was subsequently withdrawn, leaving 10 patients treated. Minor adverse events (AEs) were experienced by seven subjects (63.6%). There was one serious AE (diverticulitis) unrelated to the device or procedure. One subject experienced AEs that were judged “likely” to be procedure related (arthralgia/musculoskeletal discomfort) and all resolved within 6 days of injection. All other AEs were unrelated to the device or procedure. Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain scores improved significantly over time (ANOVA, p < 0.0001, 12.0 ± 1.2 preinjection, 3.3 ± 2.9 one year postinjection, and 72.5% WOMAC pain improvement). There was significant positive correlation between white blood cell concentration in APS and improvement in WOMAC pain scores.

ObjectivesTo compare gastrointestinal (GI) tolerability and patient preference for the new 625 mg formulation of nelfinavir (NFV) and the marketed 250 mg tablets (Viracept s ) in HIV-1-infected patients. MethodsVirologically controlled patients (n 5 126) treated with a nelfinavir (NFV) 250 mg-containing regimen for ! 8 weeks completed a stool diary for 14 days to assess baseline bowel function. After switching to the NFV 625 mg formulation [1250 mg twice a day (bid)] for 28 days, patients continued their stool diaries and at study completion answered a questionnaire regarding formulation preferences. ResultsThe incidence and mean weekly duration of GI upset over a 2-week period were lower with NFV 625 mg than with NFV 250 mg (79.8% vs. 84.9% of patients and 2.1 vs. 3.0 days, respectively). Fewer patients experienced moderate or severe diarrhoea with NFV 625 mg (6.5% vs. 11.1%), and the incidence of investigator-assessed diarrhoea also decreased with NFV 625 mg. Importantly, there was a significant improvement overall in the incidence of diarrhoea (any grade) when patients switched to NFV 625 mg [38 of 124 (31%) improving, 69 of 124 (56%) stable and 17 of 124 (14%) worsening on NFV 625 mg; Po0.01]. At study completion, most patients expressed a preference to continue treatment with NFV 625 mg [112 of 122 (91.8%); Po0.0001], with only one patient (0.8%) preferring to resume treatment with NFV 250 mg. The new formulation was well tolerated with no new safety concerns. ConclusionsThe new NFV 625 mg formulation is better tolerated and preferred by patients switching from NFV 250 mg tablets. By reducing the daily pill count and improving GI tolerability, the NFV 625 mg formulation may enhance patient adherence to NFV-containing antiretroviral regimens and thus potentially improve virological outcomes.
