ABSTRACT: Purpose
GSK2982772 is a selective inhibitor of receptor-interacting protein kinase-1, with a 2-3 h half-life. This study evaluated if a once-daily modified-release formulation of GSK2982772 could be developed with no significant food effect.Methods
Part A evaluated the pharmacokinetics of GSK2982772 following fasted single-dose (120 mg) administration of two matrix minitab formulations (MT-8 h and MT-12 h) vs 120 mg immediate release (IR) and MT-12 h with a high-fat meal. Part B evaluated once-daily MT-12 h for 3 days at three dose levels. Part C evaluated a matrix monolithic (MM-12 h) formulation at two dose levels in different prandial states.Results
All modified-release formulations dosed in the fasted state reduced maximum plasma concentration (Cmax), delayed time to Cmax, and decreased area under the curve (AUC) vs IR. When MT-12 h or MM-12 h were co-administered with a meal (standard or high-fat) Cmax and AUC increased. Dosing MM-12 h 1 h before a standard or high-fat meal had minimal impact on exposure vs fasted.Conclusions
MT-12 h and MM-12 h provided a QD pharmacokinetic profile in the fasted state, however when MT-12 h was dosed with a high-fat meal a QD profile was not maintained. ( ClinicalTrials.gov Identifier: NCT03266172).

Project description:PurposeGSK2982772 is a selective inhibitor of receptor-interacting protein kinase-1 (RIPK1) with a short 2- to 3-h half-life. In a previous modified-release (MR) study, a matrix monolithic formulation (80% GSK2982772 released over 12 h) provided a once-daily (QD) pharmacokinetic (PK) profile in the fasted state; however, it was susceptible to food effects. The current study evaluated the safety and PK of MR formulations using GSK proprietary DiffCORE™ technology.MethodsPart A evaluated PK following single-dose (240 mg) fasted and fed (high-fat meal) administration of three DiffCORE MR formulations within pre-defined in vitro extremes of 80% GSK2982772 released over 12 h (MR-12 h) to 80% GSK2982772 released over 18 h (MR-18 h) versus an immediate-release formulation. Part B evaluated MR-16 h (120-960 mg) in different prandial states.ResultsPharmacokinetic profiles for all MR formulations and doses tested in the fasted and fed states were consistent with QD dosing.ConclusionsThe DiffCORE technology overcame the food effect vulnerability observed with the matrix monolithic formulation. The MR-16 h formulation was selected for further clinical development as a QD dosing regimen (NCT03649412 September 26, 2018).

Project description:IntroductionTrimetazidine (TMZ) is an anti-ischemic metabolic agent that has been shown to be efficacious in angina treatment, both in monotherapy and in combination. A new formulation of TMZ modified-release (MR) 80 mg was developed, which is to be taken once daily (od), instead of twice daily (bid) for the currently available TMZ MR 35 mg, with the aim of simplifying the medication regimen.MethodsThe present study was an international, multicenter, randomized, double-blind, parallel-group phase III study with a 12-week treatment period. The safety of TMZ MR 80 mg once daily was assessed compared to TMZ MR 35 mg twice daily, in patients previously treated successfully by the latter. Emergent adverse events (EAEs), biological parameters, vital signs, 12-lead resting ECG (electrocardiogram) and Canadian Cardiovascular Society (CCS) classification were recorded.ResultsOne-hundred and sixty-five patients previously diagnosed with stable angina pectoris on treatment were randomized to receive either TMZ MR 80 mg od or TMZ MR 35 mg bid. In the TMZ MR 80 mg group, fewer patients had ≥ 1 EAE (17.1 vs. 22.9% in the TMZ MR 35 mg group). Serious EAEs were reported by three patients in each group. No EAE required dose modification, withdrawal, or temporary interruption of study treatments. Vital signs, 12-lead ECG, and laboratory parameters did not change. No worsening in CCS classes was observed with either treatment.ConclusionsTMZ MR 80 mg od and TMZ MR 35 mg bid have similar safety profiles. This new once-daily formulation could improve patient compliance with therapy, thereby enhancing clinical benefit.Trial registrationISRCTN registry, ISRCTN 84362208.FundingInstitut de Recherches Internationales Servier and Servier, Moscow, Russian Federation.

Project description:BackgroundTacrolimus is metabolized by cytochrome P450 (CYP) 3A4 and 3A5. We investigated the influence of CYP3A5 polymorphism and concurrent use of azole antifungal agents (AZ) on the pharmacokinetics of a once-daily modified-release tacrolimus formulation (Tac-QD) in patients after hematopoietic stem cell transplantation (HSCT).Design and methodsTwenty-four patients receiving allogeneic HSCT were enrolled. Genotyping for CYP3A5*3 was done by a PCR-restriction fragment length polymorphism method. Trough blood concentrations (C0) of tacrolimus were measured by chemiluminescence magnetic microparticle immunoassay. Continuous infusion of tacrolimus was administered from the day before transplantation and was switched to Tac-QD after adequate oral intake.ResultsThirteen patients had a CYP3A5*3/*3 genotype, and 11 patients had a CYP3A5*1/*1 or *1/*3 genotype. No significant difference was observed in daily dosages and the C0 of tacrolimus between the two genotype groups without AZ. However, in patients who were co-administered AZ, the C0 values of tacrolimus were higher in patients with the CYP3A5*3/*3 allele than with the CYP3A5*1 allele (P = 0.034), although daily doses of Tac-QD in patients with CYP3A5*3/*3 were significantly lower than those with the CYP3A5*1 allele (P = 0.041). The cumulative incidence of acute kidney injury was higher in patients with the CYP3A5*3/*3 than with the CYP3A5*1 allele when AZ was co-administered. The decrement for daily dosage of Tac-QD was significantly greater in patients expressing the CYP3A5*3/*3 than the CYP3A5*1 allele.ConclusionsCYP3A5 genotyping may be useful for safe and effective immunosuppressive therapy with Tac-QD in HSCT patients in whom the use of AZ is anticipated.

Project description:IntroductionTofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). To provide additional clinical evidence in regulatory submissions for a modified-release (MR) once-daily (QD) tofacitinib formulation, we compared real-world adherence and effectiveness between patients initiating the MR QD formulation and patients initiating an immediate-release (IR) twice-daily (BID) formulation.MethodsTwo noninterventional cohort studies were conducted. First, adherence and two effectiveness proxies were compared between patients with RA who newly initiated tofacitinib MR 11 mg QD or IR 5 mg BID in the IBM® MarketScan® Commercial and Medicare Supplemental US insurance claims databases (March 2016-October 2018). Second, using data collected in the Corrona US RA Registry (February 2016-August 2019), two Clinical Disease Activity Index (CDAI)-based measures of effectiveness were compared between tofacitinib MR 11 mg QD and IR 5 mg BID, and against noninferiority criteria derived from placebo-controlled clinical trials of the tofacitinib IR formulation. Multiple sensitivity analyses of the registry data were conducted to reassure regulators of consistent results across different assumptions.ResultsIn each study, approximately two-thirds of patients initiated the MR formulation. In the claims database study, improved adherence and at least comparable effectiveness were observed with tofacitinib MR vs IR over 12 months, particularly in patients without prior advanced therapy. In the registry study, the noninferiority of tofacitinib MR vs IR was demonstrated for both CDAI outcomes at ~6 months; this finding was robust across multiple sensitivity analyses.ConclusionThese results demonstrate the value of real-world evidence from complementary data sources in understanding the impact of medication adherence with a QD formulation in clinical practice. These analyses were suitable for regulatory consideration as an important component of evidence for the comparability of tofacitinib MR 11 mg QD vs IR 5 mg BID in patients with RA.Trial registrationClaims database study: ClinicalTrials.gov identifier NCT04018001, retrospectively registered July 12, 2019.

Project description:An important goal of effective rosacea treatment is to maximize the duration of remission. This was a two-part study. Part 1 was a multicenter, open-label, 12-week study in which adults with moderate or severe inflammatory lesions (papules and pustules) of rosacea received subantibiotic dose oral doxycycline 40 mg modified release (SDD40 ) and topical metronidazole gel 1%. Part 2 was a multicenter, randomized, double-blind, placebo-controlled, 40-week study in which successfully treated subjects received once-daily SDD40 or placebo capsules. The primary objective was to assess relapse and efficacy during long-term use of SDD40 versus placebo. Relapse was defined as a return to baseline investigator global assessment (IGA) or lesion count, or any other necessary change in treatment. Part 1 enrolled 235 subjects. Sixty-five subjects in the SDD40 treatment group and 65 subjects in the placebo group met the definition of treatment success at week 12, and were included in the Part 2 analysis. At the end of Part 2, half as many subjects in the SDD40 group had relapsed compared to the placebo group (13.8% [n = 9] vs. 27.7% [n = 18], p < 0.05). Significant differences in the median change in inflammatory lesion counts were also observed (p < 0.05). Adverse events (AEs) were generally mild-moderate in severity, and most were not treatment-related. Stinging/burning responded with more improvement in subjects treated with SDD40 . After 52 weeks of once-daily treatment, subantibiotic dose doxycycline significantly reduced the relapse rate and inflammatory lesion counts in subjects with moderate-to-severe inflammatory rosacea.

Project description:To evaluate and to compare the bioavailability, the influence of food intake on the bioavailability, and the safety and tolerability of a newly-developed oxycodone once-daily (OOD) prolonged-release tablet with an established oxycodone twice-daily (OTD) prolonged-release tablet after single-dose administration under fasting or fed conditions as well as after multiple-dose administration.Three single-center, open-label, randomized, balanced, two-treatment, two-period, two-sequence crossover studies were conducted. In each study, 36 healthy volunteers were randomized to receive 10 mg oxycodone daily as OOD (oxycodone HCL 10-mg PR tablets XL (Develco Pharma Schweiz AG, Pratteln, Switzerland); administration of 1 tablet in the morning) or as OTD (reference formulation: oxygesic 5-mg tablets (Mundipharma GmbH, Limburg an der Lahn, Germany); administration of 1 tablet in the morning and 1 tablet in the evening). Tablets were administered once daily or twice daily under fasting conditions (study 1) or under fed conditions (study 2) as well as after multiple-dose administration (study 3). A sufficient number of blood samples were taken for describing plasma profiles and for calculation of pharmacokinetic parameters. Plasma concentrations of oxycodone were determined by LC-MS/MS. Safety and tolerability were monitored and assessed in all three studies.Plasma profiles of OOD reveal sustained concentrations of oxycodone over the complete dosing interval of 24 hours. In comparison to the OTD reference formulation, the OOD test formulation showed a slightly slower increase of concentrations within the absorption phase and similar plasma concentrations at the maximum and at the end of the dosing interval (24 hours). Extent of bioavailability (AUC), maximum plasma concentrations (Cmax), and plasma concentrations at the end of the dosing interval (C?,ss,24h) of OOD could be classified as comparable to OTD considering 90% confidence intervals (CIs) and acceptance limits of 80.00 - 125.00%. Bioavailability of OOD was not influenced by concomitant food intake. OOD and OTD were generally well tolerated, a difference between the two products could not be observed.The new 10-mg OOD formulation provides sustained oxycodone plasma concentrations over the dosing interval of 24 hours and is suitable for once-daily administration. Bioavailability of OOD could be classified as comparable to the twice-daily administration of the OTD reference formulation. The new formulation widens and optimizes the range of strong opioid drug products in patient-centered therapy of chronic pain with simplified dosing and better compliance.?.

Project description:IntroductionBilastine is a second-generation H1 antihistamine indicated for the symptomatic treatment of allergic rhinoconjunctivitis and urticaria. On the basis of the demonstrated efficacy and safety of the oral formulation, a new ophthalmic formulation of bilastine was recently developed. Previous preclinical studies had indicated that bilastine is mainly absorbed by the conjunctiva and shows low plasma concentration. The objective of this study was to evaluate the pharmacokinetics and safety of ophthalmic bilastine (6 mg/mL) after single and multiple dose administration at steady state in healthy adults.MethodsThis was an open-label, single-centre, phase I, bioavailability clinical trial. One drop of the bilastine ophthalmic formulation was administered once daily in each eye of the subjects for 5 days. Bilastine plasma concentrations were measured by HPLC-MS/MS. Adverse drug reactions were recorded for each subject during drug administration and follow-up visits.ResultsTwelve healthy subjects (age 18-55 years) were included in the study. After multiple dose administration, bilastine reached a mean (± SD) maximum blood concentrations of 2682.26 ± 1615.88 pg/mL at a median time of 2.50 h (range 1.25-4.00 h). The half-life of bilastine in plasma was 7.88 ± 6.72 h. Steady state AUC was 19,512.51 ± 9248.76 h·pg/mL. Adverse events were mild and transient, consisting mainly of dysgeusia.ConclusionsBilastine once-daily ophthalmic formulation 6 mg/mL is absorbed into the bloodstream in low amounts by the ophthalmic route. The bilastine ophthalmic formulation showed a good safety profile after multiple dose administration.

Project description:This open-label study aimed to compare once-daily and twice-daily pramipexole extended release (PER) treatment in Parkinson's disease (PD). PD patients on dopamine agonist therapy, but with unsatisfactory control, were enrolled. Existing agonist doses were switched into equivalent PER doses. Subjects were consecutively enrolled into either once-daily-first or twice-daily-first groups and received the prescribed amount in one or two, respectively, daily doses for 8 weeks. For the second period, subjects switched regimens in a crossover manner. The forty-four patients completed a questionnaire requesting preference during their last visit. We measured the UPDRS-III, Hoehn and Yahr stages (H&Y) in medication-on state, Parkinson's disease sleep scale (PDSS), and Epworth Sleepiness Scale. Eighteen patients preferred a twice-daily regimen, 12 preferred a once-daily regimen, and 14 had no preference. After the trial, 14 subjects wanted to be on a once-daily regimen, 25 chose a twice-daily regimen, and 5 wanted to maintain the prestudy regimen. Main reasons for choosing the twice-daily regimen were decreased off-duration, more tolerable off-symptoms, and psychological stability. The mean UPDRS-III, H&Y, and PDSS were not different. Daytime sleepiness was significantly high in the once-daily regimen, whereas nocturnal hallucinations were more common in the twice-daily. Multiple dosing should be considered if once-daily dosing is unsatisfactory. This study is registered as NCT01515774 at ClinicalTrials.gov.

Project description:Hydrocodone bitartrate extended release (Hysingla® ER, HYD) was previously studied in a 12-week randomized, double-blind, placebo-controlled trial and a 52-week open-label safety study. Both of these preapproval studies allowed dose titration to efficacy. The purpose of the present analysis was to compare dosing and utilization patterns in these previous clinical trials with real-world data (RWD) usage in a retrospective claim analysis performed 12-14 months post approval in the US.In the claim analysis (Truven Health Analytics MarketScan® Research Database), patients prescribed HYD between January 1, 2015, and April 30, 2016, were followed for up to 6 months of continuous HYD use. Daily average consumption (DACON), initial dose, rescue opioid use and total milligram dose over time were also evaluated.HYD daily dose stabilized at ~60 mg dose once daily across all three studies. There was also a reduced need for rescue medication with HYD, resulting in a lower total opioid milligram dose over time. In the claim analysis, the mean monthly HYD dose increased from 49 to 55 mg in month 2 and then remained stable through month 6. The mean (standard deviation [SD]) time on drug was 79.5 days (61.42 days), and DACON was 1.04 pills/day, corresponding to the approved full prescribing information (FPI) and once-daily dosing.In 12-14 months post approval, real-world dosing and utilization of HYD mirrored registration and open-label study findings, with stable once-daily dosing of ~60 mg and no increase in rescue medicine utilization.

Project description:Background: Tacrolimus is the calcineurin inhibitor of choice for preventing acute rejection episodes in kidney transplant patients. However, tacrolimus has a narrow therapeutic range that requires regular monitoring of blood concentrations to minimize toxicity. A new once-daily tacrolimus formulation, LCP-tacrolimus (LCPT), has been developed, which uses MeltDose™ drug-delivery technology to control drug release and enhance overall bioavailability. Our study compared dosing of LCPT with current standard-of-care tacrolimus [immediate-release tacrolimus (IR-Tac) or prolonged-release tacrolimus (PR-Tac)] during the 6 months following de novo kidney transplantation. Comparisons of graft function, clinical outcomes, safety, and tolerability for LCPT versus IR-Tac/PR-Tac were also performed. Methods: Standard immunological risk patients with end-stage renal disease who had received a de novo kidney transplant were randomized (1:1) to LCPT (N = 200) or IR-Tac/PR-Tac (N = 201). Results: Least squares (LS) mean tacrolimus total daily dose from Week 3 to Month 6 was significantly lower for LCPT than for IR-Tac/PR-Tac. Although LS mean tacrolimus trough levels were significantly higher for LCPT than IR-Tac/PR-Tac, tacrolimus trough levels remained within the standard reference range for most patients. There were no differences between the groups in treatment failure measures or safety profile. Conclusion: LCPT can achieve similar clinical outcomes to other tacrolimus formulations, with a lower daily dose. Clinical Trial Registration: https://clinicaltrials.gov/, identifier NCT02432833.
