Purpose The aim of this study was to evaluate the safety, tolerability, and pharmacokinetic parameters of up to 15 dose levels of ONO-4232, a selective agonist for the EP4 subtype of the prostaglandin E2 receptor, with a dual left ventricular lusitropic and venodilatory action, in healthy, adult, male and female volunteers. Methods In this randomized, single-center, double-blind, placebo-controlled, single-dose, sequential-group escalation, first in human study, ONO-4232 (0.001, 0.003, 0.01, 0.02, 0.04, 0.08, 0.12, 0.15, 0.18, or 0.27 ng/kg/min) or placebo was administered as a continuous intravenous infusion over 3 hours. Safety, tolerability, and pharmacokinetic data were collected during dosing and over a period of 3 days (Day -1 to Day 2), and at the follow-up visit (Day 7 [±2 days]). Findings Fifty-seven subjects received ONO-4232 and 19 subjects received placebo. Ten of the planned 15 cohorts (dose range, 0.001-0.27 ng/kg/min) were conducted. A total of 34 treatment-emergent adverse events (TEAEs) were reported in 23 subjects. Overall, the majority of TEAEs were mild. No serious TEAEs or deaths were reported and no subjects discontinued due to adverse events. The most frequently reported TEAE was infusion site erythema. A decrease in systolic blood pressure from baseline occurred for ONO-4232 subjects compared with placebo that was statistically significant for the 0.08 ng/kg/min dose, and a dose-dependent increase in heart rate starting at 0.04 ng/kg/min and achieving statistical significance compared with placebo at 0.15 ng/kg/min and above. More orthostatic events occurred in the higher-dose groups and the dose escalation was terminated due to increasing occurrences of orthostatic hypotension/intolerance. Plasma concentrations of ONO-4232 reached steady state approximately 2 hours after the start of infusion and then declined rapidly after the end of infusion, and systemic exposure appeared to increase in a dose-proportional manner. Approximately 30% of the administered dose of ONO-4232 was excreted in the urine. Implications In healthy adults ONO-4232 was generally well tolerated in the dose range of 0.001 to 0.27 ng/kg/min. There were dose-related changes in systolic blood pressure and heart rate. Infusion site erythema, which was likely associated with a venodilatory effect and possible evidence for the pharmacologic effects of ONO-4232, occurred increasingly with increasing dose. Pharmacokinetic parameters appeared to be dose-proportional. The study results support further evaluation of the cardiovascular effects of this first-in-class selective left ventricular lusitropic and venodilatory drug in patients with acutely decompensated heart failure. © 2016 The Authors.

Provided is a levodopa prodrug that overcomes the problems attributed to the blood kinetics of levodopa such as large number of doses and the incidence of side effects due to frequent dosing. (2S)-2-Amino-3-(3,4-bis((2-(benzoyloxy)-2-methylpropanoyl)oxy)phenyl)propanoic acid, a salt thereof, or a solvate thereof is a levodopa prodrug, and provides a flat blood concentration-time profile of levodopa through oral administration, and therefore is useful as a preventive and/or therapeutic agent for Parkinsons disease and/or Parkinsons syndrome that overcomes the problems associated with pharmaceutical preparations of levodopa.

We report the results of a multicenter phase 1 dose-escalation study of the selective Bruton tyrosine kinase (BTK) inhibitor ONO/GS-4059 in 90 patients with relapsed/refractory B-cell malignancies. There were9dose-escalation cohorts ranging from20mg to 600 mg once daily with twice-daily regimens of 240 mg and 300 mg. Twenty-four of 25 evaluable chronic lymphocytic leukemia (CLL) patients (96%) responded to ONO/GS-4059, witha median treatment durationof 80 weeks;21CLL patients remainontreatment. Lymph node responses were rapid and associated with a concurrent lymphocytosis. Eleven of 12 evaluable patients with mantle cell lymphoma (92%) responded (median treatment duration, 40 weeks). Eleven of 31 non-germinal centerB-cell diffuse large B-cell lymphoma patients (35%) responded but median treatment duration was 12 weeks due to development of progressive disease. ONO/GS-4059 was very well tolerated with 75% of adverse events (AEs) being Common Toxicity Criteria for Adverse Events version 4.0 grade 1 or grade 2. Grade 3/4 AEs were mainly hematologic and recovered spontaneously during therapy. One CLL patient experienced a grade 3 treatment-related bleeding event (spontaneous muscle hematoma) but no clinically significant diarrhea, cardiac dysrhythmias, or arthralgia were observed. No maximal tolerated dose (MTD) was reached in the CLL cohort. In the non-Hodgkin lymphoma cohort, 4 patients developed a doselimiting toxicity, yielding an MTD of 480 mg once daily. ONO/GS-4059 has significant activity in relapsed/refractory B-cell malignancies without major drug-related toxicity. The selectivity of ONO/GS-4059 should confer advantages in combination therapies.

Purpose To investigate safety, tolerability, and pharmacokinetic properties of single and multiple doses of novel translocator protein 18 kDa antagonist ONO-2952 in healthy subjects. Methods Double-blind, placebo-controlled single (SAD) and multiple (MAD) dose escalation studies were conducted. Healthy men and women aged 18 to 55 years inclusive and without history of psychiatric disorders were eligible. Forty-eight volunteers received single doses of ONO-2952 (3, 10, 30, 100, 200, or 400 mg) or placebo under fasted conditions (SAD study), and 36 received ONO-2952 (30, 60, or 100 mg/d) or placebo for 21 consecutive days under fed conditions (MAD study). ONO-2952 10 and 200 mg were administered under fasted and fed conditions in the SAD study to investigate the effect of food on the absorption of ONO-2952. Safety assessments included adverse events, vital signs, 12-lead ECGs, and clinical laboratory evaluations. Plasma and urine pharmacokinetic profiles of ONO-2952 were determined. Findings Across both studies, mean age ranged from 29.8 to 39.8 years, most participants were white, and the proportion of female volunteers was 52%. No treatment or dose-related trends in adverse events were observed. The most frequent adverse events were headache and presyncope (n = 2 each [SAD study]) and constipation and headache (n = 3 each [MAD study]). All headache and constipation episodes were possibly related to the study drug. Plasma ONO-2952 concentrations peaked 2.5 to 3.5 hours (SAD study) and 3.0 to 4.0 hours (MAD study) postdose. ONO-2952 systemic exposure increased less than dose proportionally under fasted conditions. Fed conditions significantly increased exposure compared with fasted conditions: geometric mean ratios of Cmax (90% CIs) were 229% (176-299 [10 mg]) and 778% (623-971 [200 mg]), and AUClast were 159% (131-192 [10 mg]) and 382% (288-506 [200 mg]). In the MAD study, the systemic exposure of ONO-2952 increased in a slightly greater than dose-proportional manner. Geometric mean accumulation ratios (95% CI) of AUC24 were 2.50 (2.09-2.98 [30 mg]), 2.23 (1.85-2.68 [60 mg]), and 2.73 (2.10-3.55 [100 mg]); and Cmax were 1.65 (1.43-1.90 [30 mg]), 1.56 (1.31-1.85 [60 mg]), and 1.85 (1.38-2.49 [100 mg]). Implications ONO-2952 was safe and well tolerated in these early clinical studies investigating safety, tolerability, and pharmacokinetic properties of single and multiple doses. ONO-2952 systemic exposure increased in a less than dose-proportional manner under fasted conditions and in a slightly greater than dose-proportional manner under fed conditions. These results support the progression of ONO-2952 to further studies in humans. SAD study: ClinicalTials.gov identifier: NCT01364441.
