    Abstract Relapsed/refractory (r/r) acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) outcomes remain poor. A targeted cluster of differentiation (CD)33 × CD3 bispecific antibody, JNJ-67571244, was assessed to identify the maximum tolerated dose (MTD), recommended phase II dose (RP2D), safety and tolerability, and preliminary clinical activity in patients with r/rAML or r/rMDS. This first-in-human, open-label, phase I, dose-escalation/dose-expansion study included patients with r/rAML or r/rMDS who were ineligible for or had exhausted standard therapeutic options. JNJ-67571244 was administered intravenously or subcutaneously using step-up dosing until ≥1 discontinuation condition was met. Outcomes included safety/tolerability, preliminary clinical activity, and systemic pharmacokinetics and pharmacodynamics. The study was terminated after evaluating 10 dose-escalation cohorts (n = 68) and before starting dose-expansion. Overall, 11 (16.2%) patients experienced ≥1 dose-limiting toxicity; all experienced ≥1 treatment-emergent adverse event (TEAE; treatment related: 60 [88.2%]); and 64 (94.1%) experienced ≥1 TEAE of Grade ≥3 toxicity (treatment related: 28 [41.2%]). Although some patients had temporary disease burden reductions, no responses were seen. JNJ-67571244 administration increased multiple cytokines, which coincided with incidence of cytokine release syndrome, infusion-related reactions, and elevated liver function tests. A prolonged step-up strategy was tested to improve tolerability, though this approach did not prevent hepatotoxicity. T-cell activation following treatment suggested target engagement but did not correlate with clinical activity. Safely reaching the projected exposure level for JNJ-67571244 efficacy was not achieved, thus MTD and RP2D were not determined.

    Abstract This study aimed to identify a recommended phase II dose and evaluate the safety, tolerability, pharmacokinetics/pharmacodynamics, and preliminary clinical activity of JNJ-63709178, a CD123/CD3 dual-targeting antibody, in patients with relapsed or refractory acute myeloid leukemia. Intravenous (i.v.) and subcutaneous (s.c.) administration of JNJ-63709178 were evaluated. The i.v. infusions were administered once every 2 weeks (cohorts 1-5 [n = 17]) or twice weekly (cohorts 6-11 [n = 36]). A twice-weekly s.c. dosing regimen with step-up dosing was also studied (s.c. cohorts 1-2 [n = 9]). Treatment-emergent adverse events (TEAEs) greater than or equal to grade 3 were observed in 11 (65%) patients in cohorts 1-5 and 33 (92%) patients in cohorts 6-11. At the highest i.v. dose (4.8 μg/kg), 5 (71%) patients discontinued treatment due to TEAEs. For s.c. administration (n = 9), eight (89%) patients experienced TEAEs greater than or equal to grade 3 and injection site reactions (≤ grade 3) emerged in all patients. At 4.8 μg/kg (i.v. and s.c.), the mean maximum serum concentrations were 30.3 and 3.59 ng/ml, respectively. Increases in multiple cytokines were observed following i.v. and s.c. administrations, and step-up dosing strategies did not mitigate cytokine production or improve the safety profile and led to limited duration of treatment. Minimal clinical activity was observed across all cohorts. The i.v. and s.c. dosing of JNJ-63709178 was associated with suboptimal drug exposure, unfavorable safety profiles, limited clinical activity, and inability to identify a recommended phase II dose.

    Abstract Focal and segmental glomerulosclerosis (FSGS) is a pathologic entity that is a common and increasing cause of end-stage renal disease. Typical manifestations include proteinuria, hypertension, worsening renal insufficiency, and, frequently, renal failure. The etiology, however, remains unknown in a majority of patients. There is an estimated recurrence rate of 30% to 40% in renal transplant patients, suggesting that the pathogenesis is not solely a result of intrinsic kidney disease. Although some of its characteristics have been reported, the precise identification of a circulating factor associated with FSGS has not been made. Remarkable progress has been made in recent years regarding biologic mechanisms surrounding FSGS and proteinuria. Insight into the pathogenesis of FSGS has been gained through the study of hereditary forms of FSGS and nephrotic syndromes. Mutations in cytoskeletal proteins that affect podocyte structure have been the target until recently. Here we review the current understanding of this glomerular disease and areas for future concentration.

    Abstract Introduction: Elevated interleukin (IL)-6 occurs in patients with active rheumatoid arthritis (RA), which has been shown to lead to a decrease in cytochrome P450 (CYP) enzyme activity and alterations in drug concentrations metabolized by CYP. IL-6 signaling blockade by IL-6 receptor (IL-6R) antagonists may reverse this effect of IL-6 and restore CYP activity. This study evaluated the pharmacokinetic profile of simvastatin (a CYP3A4 substrate) before and 1 week after a single dose of sarilumab (a human monoclonal antibody [mAb] blocking the IL-6Rα) in patients with RA, to assess potential interaction.
    Methods: Nineteen patients with active RA received oral simvastatin 40 mg 1 day before and 7 days after subcutaneous injection of sarilumab 200 mg. The pharmacokinetic parameters of simvastatin and its primary metabolite, β-hydroxy-simvastatin acid, were calculated using noncompartmental analysis.
    Results: Compared with simvastatin alone, single-dose simvastatin administration 7 days after single-dose sarilumab administration in patients with RA resulted in reduced simvastatin and β-hydroxy-simvastatin acid exposure in plasma. Mean effect ratios (90 % confidence interval) for simvastatin peak plasma concentration (C
    Conclusions: Sarilumab treatment resulted in a reduction in exposure of simvastatin, consistent with reversal of IL-6-mediated CYP3A4 suppression in patients with active RA, as was reported for tocilizumab with simvastatin and for sirukumab with midazolam.

    Abstract Clopidogrel requires CYP450-mediated hepatic metabolism to form its active metabolite (clopi-H4). This randomized, placebo-controlled, crossover study was designed to characterize the effect of a high-fat or standard breakfast on adenosine diphosphate (ADP)-induced platelet aggregation and exposure to unchanged clopidogrel and clopi-H4 following clopidogrel (300-mg loading dose, 75 mg/d for 4 days) in 72 healthy men. At day 5 and as assessed by liquid chromatography-tandem mass spectrometry, unchanged clopidogrel area under the concentration- time curve from 0 to 24 hours (AUC(0-24)) increased 3.32-fold (90% confidence interval [CI], 2.88-3.84), and clopi-H4 AUC(0-24) decreased nonsignificantly by 12% (90% CI, 0.82-0.94) upon administration of clopidogrel with a standard breakfast. The estimated treatment difference in maximum platelet aggregation (MPA) induced by ADP 5 µM and assessed by light transmission aggregometry was 4.7%, with the 90% CI (0.9%-8.5%) contained within the prespecified equipotency range of ±15%. The mean ± standard deviation of day 5 inhibition of platelet aggregation was 49.7% ± 17.2% and 54.0% ± 13.3% in the fed and fasted states, respectively. Despite increased unchanged clopidogrel and slightly decreased clopi-H4 exposure following clopidogrel administration, the numerical increase in MPA in the fed versus fasted state was small and within the prespecified limit of equipotency. These findings confirm that clopidogrel can be taken with or without food.

    Abstract Focal and segmental glomerulosclerosis (FSGS) is a kidney disorder of unknown etiology, and up to 20% of patients on dialysis have been diagnosed with it. Here we show that a large family with hereditary FSGS carries a missense mutation in the TRPC6 gene on chromosome 11q, encoding the ion-channel protein transient receptor potential cation channel 6 (TRPC6). The proline-to-glutamine substitution at position 112, which occurs in a highly conserved region of the protein, enhances TRPC6-mediated calcium signals in response to agonists such as angiotensin II and appears to alter the intracellular distribution of TRPC6 protein. Previous work has emphasized the importance of cytoskeletal and structural proteins in proteinuric kidney diseases. Our findings suggest an alternative mechanism for the pathogenesis of glomerular disease.
