Project description:What is already known about this subject• Linagliptin is an oral, highly selective dipeptidyl peptidase-4 (DPP-4) inhibitor that was approved in the United States, Europe and elsewhere in 2011 for the treatment of type 2 diabetes mellitus. • The elimination of linagliptin is primarily non-renal. Therefore, a potential effect of hepatic impairment on the elimination of linagliptin may have important implications for dosing recommendations.What this study adds• This study shows that mild, moderate or severe hepatic impairment did not result in an increase in linagliptin exposure after single and multiple dosing as compared with normal hepatic function. • No linagliptin dose adjustment is required in patients with any degree of hepatic impairment.AimTo investigate whether hepatic impairment affects linagliptin pharmacokinetics, pharmacodynamics and tolerability.MethodThis open label, parallel group, single centre study enrolled patients with mild (n= 8), moderate (n= 9) or severe (n= 8) hepatic impairment and healthy subjects (n= 8). Groups were matched with regard to age, weight and gender. Primary endpoints were linagliptin exposure following 5 mg linagliptin once daily for 7 days in patients with mild and moderate hepatic impairment vs. healthy subjects or after a single 5 mg dose for patients with severe hepatic impairment vs. healthy subjects.ResultsIn mild hepatic impairment, steady-state linagliptin exposure was slightly lower than in healthy subjects [AUC(τ,ss) geometric mean ratio (GMR) 75.5%, 90% confidence interval (CI) 61.6%, 92.5%, and C(max,ss) GMR 64.4%, 90% CI 43.2%, 96.0%]. Exposure also tended to be lower in moderate hepatic impairment (AUC(τ,ss) GMR 85.5%, 90% CI 70.2%, 104.2% and C(max,ss) GMR 92.3%, 90% CI 62.8%, 135.6%). After a single dose, AUC(0,24 h) in patients with severe hepatic impairment was similar to that in healthy subjects (GMR 100.4%, 90% CI 75.0%, 134.3%) and C(max) was lower (GMR 77.0%, 90% CI 44.9%, 132.3%). Accumulation based on AUC or C(max) and renal excretion of unchanged linagliptin (≤ 7%) were comparable across groups. Median plasma DPP-4 inhibition was similar in healthy subjects (91%), and patients with mild (90%) and moderate (89%) hepatic impairment at steady-state trough concentrations, and in patients with severe hepatic impairment 24 h after a single dose (84%). Linagliptin was well tolerated.ConclusionMild, moderate or severe hepatic impairment did not result in an increase in linagliptin exposure after single and multiple dosing compared with normal hepatic function. Dose adjustment with linagliptin is not required in patients with hepatic impairment.

Project description:Nintedanib is an intracellular inhibitor of tyrosine kinases used in the treatment of non-small cell lung cancer and idiopathic pulmonary fibrosis (IPF). This phase 1 open-label study investigated the influence of mild and moderate hepatic impairment on the pharmacokinetics (PK), safety, and tolerability of nintedanib following oral administration of a single 100-mg dose. Subjects with hepatic impairment classified as Child-Pugh A (mild hepatic impairment) or Child-Pugh B (moderate hepatic impairment) were eligible. The control group comprised healthy matched subjects. Primary end points were Cmax and AUC0-∞ of nintedanib. Thirty-three subjects received nintedanib (8 in each of the Child-Pugh A and Child-Pugh B groups and 17 controls). The shape of the plasma concentration-time curve for nintedanib was similar between Child-Pugh A or B and healthy subjects. Nintedanib exposure was ∼2-fold higher in Child-Pugh A subjects and ∼8-fold higher in Child-Pugh B subjects than in healthy subjects. Adverse events were reported in 3 Child-Pugh B subjects (37.5%), no Child-Pugh A subjects, and 3 healthy subjects (17.6%). In conclusion, exposure to nintedanib was higher in Child-Pugh A and B subjects than in matched healthy subjects. A single dose of nintedanib 100 mg had an acceptable safety and tolerability profile in subjects with hepatic impairment. Results of this dedicated phase 1 study are in line with exploratory investigations into the PK of nintedanib in patients with advanced solid tumors or IPF and hepatic impairment.

Project description:Ipatasertib is a highly selective small-molecule pan-Akt inhibitor in clinical development. Ipatasertib is predominantly eliminated by the liver, and therefore, the effect of hepatic impairment on ipatasertib pharmacokinetics (PK) was evaluated. In this phase 1 open-label, parallel group study, the PK of ipatasertib were evaluated in subjects with hepatic impairment based on both the Child-Pugh and the National Cancer Institute Organ Dysfunction Working Group classification for hepatic impairment. A single dose of ipatasertib at 100 mg was administered and the PK was characterized in healthy subjects with normal hepatic function or mild, moderate, and severe hepatic impairment. Based on Child-Pugh classification, subjects with moderate and severe hepatic impairment had an ≈2- and 3-fold increase in systemic exposure (area under the plasma concentration-time curve from time 0 to infinity [AUC0-∞ ]) to ipatasertib, respectively, compared to subjects with normal hepatic function. Systemic exposure (AUC0-∞ ) to ipatasertib in subjects with mild hepatic impairment was comparable to that in subjects with normal hepatic function. In accordance with reduced clearance capacity, subjects with mild to severe hepatic impairment showed lower systemic exposure (AUC0-∞ ) of ipatasertib metabolite M1 (G-037720). Overall results were comparable between Child-Pugh and National Cancer Institute Organ Dysfunction Working Group classification criteria. Based on the results from this study, no dosage adjustment is required for ipatasertib when treating patients with mild hepatic impairment, whereas a dose reduction would be recommended for subjects with moderate or severe hepatic impairment. Based on real-world data analysis, ≈2% of the intended patient population is expected to need a modified dose due to moderate or severe hepatic impairment.

Project description:Two open-label, single-dose, parallel-group studies were conducted to characterize the pharmacokinetics of the novel antibacterial tedizolid and the safety of tedizolid phosphate, its prodrug, in renally or hepatically impaired subjects. Tedizolid pharmacokinetics in subjects with severe renal impairment without dialysis support was compared with that of matched control subjects with normal renal function. Effects of hemodialysis on tedizolid pharmacokinetics were determined in a separate cohort of subjects undergoing long-term hemodialysis. Effects of hepatic impairment on tedizolid pharmacokinetics were determined in subjects with moderate or severe hepatic impairment and compared with those of matched control subjects with normal hepatic function. Each participant received a single oral (hepatic impairment) or intravenous (renal impairment) dose of tedizolid phosphate at 200 mg; hemodialysis subjects received two doses (separated by 7 days), before and after dialysis, in a crossover fashion. The pharmacokinetics of tedizolid was similar in subjects with severe renal impairment and controls (∼8% lower area under the concentration-time curve [AUC], with a nearly identical peak concentration) and in subjects undergoing hemodialysis before and after tedizolid phosphate administration (∼9% lower AUC, with a 15% higher peak concentration); <10% of the dose was removed during 4 h of hemodialysis. Tedizolid pharmacokinetics was only minimally altered in subjects with moderate or severe hepatic impairment; the AUC was increased approximately 22% and 34%, respectively, compared with that of subjects in the control group. Tedizolid phosphate was generally well tolerated in all participants. These results suggest that tedizolid phosphate dose adjustments are not necessary in patients with any degree of renal or hepatic impairment. (This study has been registered at ClinicalTrials.gov under registration numbers NCT01452828 [renal study] and NCT01431833 [hepatic study].).

Project description:Solithromycin, a new macrolide and the first fluoroketolide, is in late-stage clinical development and, like older macrolides, is primarily metabolized and excreted through liver-dependent mechanisms. This study evaluated the safety and pharmacokinetics of solithromycin in patients with chronic liver disease. This open-label, multiple-dose study in subjects with hepatic impairment and in healthy control subjects (matched for age, weight, and sex) enrolled 8 Child-Pugh class A (mild), 8 class B (moderate), and 8 class C (severe) patients and 9 healthy controls. Subjects (n = 33) received one 800-mg dose on day 1 followed by once-daily doses of 400 mg on days 2 through 5. The most commonly reported adverse events were mild diarrhea and mild headache, and no significant differences were noted between hepatically impaired subjects and healthy controls. The pharmacokinetics of plasma solithromycin in subjects with mild and moderate impairment was similar to that in control subjects. In subjects with severe impairment, total exposure to solithromycin at steady state (area under the plasma concentration-time curve [AUC0-tau]) was decreased compared to that in control subjects, which may have been related to the higher body mass index of individuals in this group. No greater accumulation was noted in any hepatically impaired cohort on day 5 compared to that in control subjects. No decrease in dosage is therefore needed when administering solithromycin to patients with mild, moderate, or severe hepatic impairment. Solithromycin was well tolerated in this patient population, and no significant differences in safety, compared to healthy controls, were noted.

Project description:Semaglutide is a human glucagon-like peptide-1 analog that has been co-formulated with the absorption enhancer, sodium N-(8-[2-hydroxybenzoyl] amino) caprylate, for oral administration. This trial (NCT02016911) investigated whether hepatic impairment affects the pharmacokinetics, safety, and tolerability of oral semaglutide. Subjects were classified into groups: normal hepatic function (n = 24), and mild (n = 12), moderate (n = 12), or severe (n = 8) hepatic impairment according to Child-Pugh criteria, and received once-daily oral semaglutide (5 mg for 5 days followed by 10 mg for 5 days). Semaglutide plasma concentrations were measured during dosing and for up to 21 days post-last dose. Area under the semaglutide plasma concentration-time curve from 0-24 hours after the 10th dose (primary end point) and maximum semaglutide concentration after the 10th dose appeared similar across hepatic function groups. Similarly, there was no apparent effect of hepatic impairment on time to maximum semaglutide concentration (median range 1.0-1.5 hours) or half-life (geometric mean range 142-156 hours). No safety concerns were identified in subjects with hepatic impairment receiving semaglutide. Reported adverse events were in line with those observed for other glucagon-like peptide-1 receptor agonists. There was no apparent effect of hepatic impairment on the pharmacokinetics, safety, and tolerability of oral semaglutide. The results of this trial suggest that dose adjustment of oral semaglutide is not warranted in subjects with hepatic impairment.

Project description:Peficitinib (ASP015K) is a novel Janus kinase inhibitor developed for the treatment of rheumatoid arthritis (RA). The impact of hepatic impairment on the peficitinib pharmacokinetic (PK) and safety profile was investigated in non-RA subjects (n = 24) in an open-label, parallel-group, multicenter comparative study in Japan. Subjects received a single, clinically relevant, oral dose of a peficitinib 150 mg tablet under fasting conditions. Plasma PK parameters were measured for peficitinib and its metabolites H1 (sulfate and methylated metabolite), H2 (sulfate metabolite), and H4 (methylated metabolite) in subjects with normal hepatic function, mild hepatic impairment, or moderate hepatic impairment. The peficitinib area under the plasma-concentration-time curve from time 0 to infinity (AUCinf ) and maximum observed concentration (Cmax ) were not markedly different in subjects with mild hepatic impairment versus normal hepatic function. In subjects with moderate hepatic impairment versus normal hepatic function, the geometric mean ratios for peficitinib AUCinf and Cmax , were 1.92 (90% CI: 1.39, 2.66) and 1.82 (90% CI: 1.24, 2.69), respectively. Five treatment-emergent adverse events (TEAEs) were experienced by 3 subjects, 1 in each group. There were no deaths, no serious TEAEs, and no TEAEs leading to withdrawal. In summary, the PK profile was unaltered in subjects with mild hepatic impairment after a single clinically relevant dose of peficitinib, but exposure almost doubled in subjects with moderate hepatic impairment. Peficitinib dose reduction may be considered in RA patients with moderate hepatic impairment.

Project description:PURPOSE:This single-dose, randomized, open-label, parallel-group, and crossover study assessed pharmacokinetics (PK), pharmacodynamics (PD), and safety of ticagrelor in subjects on hemodialysis versus healthy subjects. METHODS:Hemodialysis subjects were randomized, receiving a single ticagrelor 90-mg dose 1 day post-hemodialysis or just before hemodialysis, with an intervening washout of ??7 days. Healthy subjects (creatinine clearance ??90 mL/min) received a single ticagrelor 90-mg dose. PK, PD (P2Y12 reaction units [PRU], inhibition of platelet aggregation [IPA]), and safety were evaluated. RESULTS:Twenty-seven subjects (14 hemodialysis, 13 healthy) received ticagrelor. The mean maximum plasma concentration (Cmax) and area under the plasma concentration curve from time zero to infinity (AUC0-?) of ticagrelor were 598.4 ng/mL and 3256.1 ng·h/mL, respectively, in pre-hemodialysis subjects; 560.3 ng/mL and 3015.1 ng·h/mL, respectively, in post-hemodialysis subjects; and 370.8 ng/mL and 2188.8 ng·h/mL, respectively, in healthy subjects. Cmax and AUC0-? of AR-C124910XX, the active metabolite, were 152.3 ng/mL and 1144.2 ng·h/mL, respectively, in pre-hemodialysis subjects; 130.8 ng/mL and 1127.8 ng·h/mL, respectively, in post-hemodialysis subjects; and 111.7 ng/mL and 1000.4 ng·h/mL, respectively, in healthy subjects. Mean IPA time curves over 24 h post-dose were almost indistinguishable for all three treatments. The greatest reduction in mean PRU occurred approximately 2 h post-dose for all three treatments. No safety or tolerability issues were identified. CONCLUSION:Hemodialysis resulted in modestly higher exposure to ticagrelor and AR-C124910XX, with no clinically significant effect on PD or tolerability. Accordingly, no dose adjustment is required for hemodialysis patients. Timing of hemodialysis has little impact on ticagrelor PK, or the effect of ticagrelor on IPA.

Project description:Tasimelteon is a circadian regulator that resets the master clock in the suprachiasmatic nuclei of the hypothalamus by binding to both melatonin MT1 and MT2 receptors making it a dual melatonin receptor agonist. Tasimelteon has been approved by the United States Food and Drug Administration for the treatment of Non-24-Hour Sleep-Wake Disorder (Non-24). Two prospective, single-center, open-label studies evaluated the pharmacokinetics of tasimelteon and its main metabolites after a single 20?mg dose administered to subjects with mild or moderate hepatic impairment or severe renal impairment, including subjects on dialysis compared to healthy controls. In subjects with mild or moderate hepatic impairment, exposure to tasimelteon after a single 20?mg dose, as measured by area under the plasma concentration-time curve to infinity, was increased by approximately 2-fold. There was no apparent relationship between tasimelteon clearance and renal function. No safety concerns were apparent in either study. Based on these results, the changes in the pharmacokinetics of tasimelteon due to mild or moderate hepatic or severe renal impairment are not considered clinically relevant, and no dose adjustment is necessary in these patients.

Project description:AIMS:Human cytomegalovirus constitutes a prevalent and serious threat to immunocompromised individuals and requires new treatments. Letermovir is a novel viral-terminase inhibitor that has demonstrated prophylactic/pre-emptive activity against human cytomegalovirus in Phase 2 and 3 transplant trials. As unchanged letermovir is primarily excreted via the liver by bile, this trial aimed to assess the effect of hepatic impairment on letermovir pharmacokinetics. METHODS:Phase 1, open-label, parallel-group pharmacokinetic and safety comparison of multiple once-daily oral letermovir in female subjects with hepatic impairment and healthy matched controls. For 8 days, subjects with moderate hepatic impairment (n = 8) and their matched healthy controls (n = 9) received 60 mg letermovir/day and those with severe hepatic impairment (n = 8) and their matched healthy controls (n = 8) received 30 mg letermovir/day. Pharmacokinetic parameters were determined from blood samples. RESULTS:For subjects with moderate hepatic impairment, maximal observed concentration at steady state (Css,max ) and the area under the concentration vs. time curve over a dosing interval at steady state (AUC?,ss ) for total letermovir were 1.37-fold (90% confidence interval: 0.87, 2.17) and 1.59-fold (0.98, 2.57) higher, respectively, than in healthy subjects. For subjects with severe hepatic impairment, Css,max and AUC?,ss values of total letermovir were 2.34-fold (1.91, 2.88) and 3.82-fold (2.94, 4.97) higher, respectively, compared with healthy subjects. CONCLUSIONS:Moderate hepatic impairment increased exposure to letermovir <2-fold, while severe hepatic impairment increased letermovir exposure approximately 4-fold as compared with healthy subjects. Letermovir 60/30 mg/day was generally well-tolerated in subjects with hepatic impairment.
