By the first year after transplantation, biopsy-confirmed acute rejection was less frequent with alemtuzumab than with conventional therapy. The apparent superiority of alemtuzumab with respect to early biopsy-confirmed acute rejection was restricted to patients at low risk for transplant rejection; among high-risk patients, alemtuzumab and rabbit antithymocyte globulin had similar efficacy.

Research on the association between health locus of control and depression in chronic illness has produced contradictory findings, perhaps because of a failure to consider contextual variables. In this study of 96 hemodialysis patients, the belief that one's health is controllable was associated with less depression among Ss who had not previously experienced a failed renal transplant. This belief was associated with greater depression for Ss who had returned to dialysis following an unsuccessful transplant. This interactive effect occurred among severely ill Ss, but health locus of control was unrelated to depression among Ss with less severe disease. This pattern occurred both when control perceptions reflected a belief in the Ss' own or powerful others' (i.e., health care providers) ability to influence health outcomes. Results underscore the adaptive value of congruence between control beliefs and objective circumstances in chronic illness.

Two randomized, double-blind, placebo-controlled studies are reported that had the objective to evaluate the pharmacokinetics, pharmacodynamics, and safety of ASP015K (peficitinib), a Janus kinase (JAK) inhibitor, in healthy subjects. The single-dose study included 7 male groups (3-300 mg) and 2 female groups (30 or 200 mg), n = 8/group (6 on ASP015K and 2 on placebo in each group). The multiple-dose study included 1 female and 3 male groups, n = 12/group (9 on ASP015K and 3 on placebo in each group), who received ASP015K (30 mg) or placebo every 12 hours (twice a day) for 14 days. In the single-dose study, plasma ASP015K concentration increased dose-proportionally. Food increased ASP015K exposure (AUC ) by 27%. Mean peak JAK inhibition increased with dose, from 6% at 4 hours (median) following ASP015K 3 mg to 93% (range, 89%-98%) at 2 hours (median) after ASP015K 300 mg. In the multiple-dose study, ASP015K plasma exposure reached steady state by day 3. On day 14, mean ASP015K peak concentration was 38%-65% higher than after the first dose; peak JAK inhibition following 100 or 200 mg twice daily was >85%. The most common adverse events (AEs) were neutropenia, headache, and abdominal pain; no serious AEs occurred. The safety findings at pharmacologically effective doses of ASP015K support further clinical development.

These results suggest that the local delivery of antiproliferative agents using a thermosensitive, injectable biodegradable copolymer (ReGel) for sustained delivery is a promising strategy to inhibit neointimal hyperplasia of arteriovenous hemodialysis grafts.
