Background:Many patients experience inadequate pain control due to limited options that are both efficacious and safe for treating moderate-to-severe acute pain; therefore, opioids are still frequently prescribed for their effectiveness despite known tolerability issues and safety concerns. Suzetrigine, an oral, non-opioid, offers a promising alternative by selectively inhibiting the voltage-gated sodium channel 1.8 (NaV1.8), a novel therapeutic target for pain management. Given the high selectivity of suzetrigine for NaV1.8 (does not bind to other sodium channels/receptors with CNS activity), suzetrigine does not have CNS side effects or addictive potential associated with opioids. In the largest randomized, controlled phase 3 trials in established acute pain models, suzetrigine monotherapy demonstrated statistically significant and clinically meaningful reduction in moderate-to-severe acute pain compared to placebo. Methods:To evaluate the safety and effectiveness of suzetrigine for the treatment of moderate-to-severe-acute surgical and non-surgical pain conditions, we conducted a phase 3, single-arm study in adults with moderate or severe acute pain on the verbal categorical rating scale and ≥4 on the numeric pain rating scale following surgical procedures or after presenting to a medical facility with moderate or severe acute pain of new origin. Participants received suzetrigine (100mg then 50mg every 12hrs) for 14 days or pain resolution, whichever came first. The primary endpoint was safety. The secondary endpoint was participant perception of suzetrigine's effectiveness in treating acute pain at the end of treatment using a patient global assessment. Results:Suzetrigine was generally safe and well-tolerated in participants (N=256) with a range of surgical and non-surgical acute pain conditions; the maximum severity for most participants who had adverse events was mild (71 participants; 27.7%) or moderate (21 participants; 8.2%). Most participants (213 participants; 83.2%) rated suzetrigine's effectiveness for treating pain on a patient global assessment as good, very good, or excellent. Conclusion:Suzetrigine provides a safe and effective non-opioid, non-addictive treatment with broad applicability for moderate-to-severe acute pain. Clinicaltrialsgov Registration:NCT05661734.

Introduction: This study describes a Phase 2 evaluation of a novel flavored PEG and sulfate solution (FPSS, also known as BLI4900) developed as a preparation for colonoscopy. FPSS was formulated to provide effective and safe cleansing but optimized for electrolyte balance and taste. FPSS features a sports drink-like taste similar to an unapproved OTC PEG and sports-drink combination (PEG-SD). Methods: This multi-center, non-randomized study evaluated sequential cohorts of developmental formulations of FPSS in colonoscopy patients. FPSS and a PEG-SD control were given in split-dose (PM/AM) regimens starting the day before colonoscopy. Each FPSS dose consisted of 1 L of prep solution with 16 oz of additional water. PEG-SD was given to 19 patients (mean age 49) as 2 doses of PEG3350 (119 g) mixed with 32 oz of sports drink. The first PEG-SD dose was preceded by 10mg of bisacodyl at 3:00PM. 40 adults (mean age 58) were enrolled and prepped with the to-be-marketed FPSS formulation. Since the performing endoscopists were unblinded, blinded central reading was also performed using video recordings. Cleansing was rated with an FDA-accepted 4-point global scale (Excellent, Good, Fair, Poor), with Good or Excellent considered a Success. Colon segments were also graded on withdrawal. Lab testing and adverse events (AEs) were collected for safety. Patient prep experience was assessed via questionnaire. Results: A high rate of cleansing success was seen with FPSS, with 93% of preps rated as successful by performing endoscopists. Segmental success was also high (> 95%), including the right colon. PEG-SD had an overall success rate of 84%, with 89% success in the distal and transverse colon but only 69% success in the right colon. Blinded central reviewers evaluated both preps and rated the cleansing success of FPSS significantly higher than PEG-SD (Rater 1: FPSS = 97%, PEG-SD = 74%; Rater 2: FPSS = 97%, PEG-SD = 68%). FPSS resulted in low rates of expected bowel prep symptoms. Patient acceptance scores (Table 1) were high, with 97% of FPSS patients rating their experience excellent or good versus 73.7% for PEG-SD (P< 0.05). 68% of patients agreed that FPSS tasted like a sports drink. Conclusion: This Phase 2 study confirms that FPSS is an effective prep for colonoscopy with low rates of expected AEs. It appears to provide better cleansing than PEG-SD, without the need for a stimulant laxative, while also reaching the high level of patient acceptance of PEG-SD.

Background Coeliac disease management is limited to strict adherence to a gluten-free diet with no approved therapies. This first-in-human phase 1 study evaluated the safety and tolerability of KAN-101, a liver-targeting glycosylation signature conjugated to a deaminated gliadin peptide designed to induce immune tolerance to gliadin.Methods Adults (aged 18-70 years) with biopsy-confirmed, HLA-DQ2.5 genotype coeliac disease were enrolled from clinical research units and hospitals in the USA. Part A of the trial was an open-label, single ascending dose study of intravenous KAN-101 using sentinel dosing in evaluation of the following cohorts: 0 center dot 15 mg/kg, 0 center dot 3 mg/kg, 0 center dot 6 mg/kg, 1 center dot 2 mg/kg, and 1 center dot 5 mg/kg. Following safety monitoring committee review of the 0 center dot 3 mg/kg dose level in part A, part B was initiated as a randomised, placebo-controlled, multiple ascending dose study. In part B, interactive response technology was used to randomly assign (5:1) patients to receive intravenous KAN-101 (0 center dot 15 mg/kg, 0 center dot 3 mg/kg, or 0 center dot 6 mg/kg) or placebo following a 1:1 assignment of the first two eligible patients in each cohort for sentinel dosing. Patients in part B received three administrations of KAN-101 or placebo followed by a 3-day oral gluten challenge (9 g per day) 1 week after completing dosing. Study personnel and patients were masked to treatment assignments in part B, and not in part A. The primary endpoint was the incidence and severity of adverse events with escalating doses of KAN-101, assessed in all patients who received any amount of study drug based on dose level received. The secondary endpoint was assessment of plasma concentrations and pharmacokinetic parameters of KAN-101 following single and multiple doses, assessed in all patients who received at least one dose and had one or more values for drug concentration. This study is registered with ClinicalTrials. gov, NCT04248855, and is completed.Findings Between Feb 7, 2020, and Oct 8, 2021, 41 patients were enrolled at ten US sites. 14 patients were assigned to part A (four 0 center dot 15 mg/kg, three 0 center dot 3 mg/kg, three 0 center dot 6 mg/kg, three 1 center dot 2 mg/kg, one 1 center dot 5 mg/kg) and 27 patients to part B (six 0 center dot 15 mg/kg with two placebo, seven 0 center dot 3 mg/kg with two placebo, and eight 0 center dot 6 mg/kg with two placebo). Treatment-related adverse events were reported in 11 (79%) of 14 patients in part A and 18 (67%) of 27 in part B (placebo two [33%] of six patients; KAN-101 16 [76%] of 21 patients), were grade 2 or lower, and were mild to moderate in severity. The most commonly observed adverse events were nausea, diarrhoea, abdominal pain, and vomiting, consistent with symptoms had by patients with coeliac disease on gluten ingestion. No grade 3-4 adverse events, serious adverse events, dose-limiting toxicities, or deaths occurred. Pharmacokinetic analyses showed KAN-101 was cleared from systemic circulation within roughly 6 h with a geometric mean half-life of 3.72 min (CV% 6 center dot 5%) to 31.72 min (83.7%), and no accumulation with repeated dosing.Interpretation KAN-101 has an acceptable safety profile in patients with coeliac disease with no dose-limiting toxicities and no maximum tolerated dose was observed. Rapid systemic clearance of KAN-101 was observed and no accumulation on repeated dosing. A future study will evaluate the safety and efficacy, including biomarker responses with a gluten challenge, of KAN-101 at doses 0 center dot 6 mg/kg and greater in patients with coeliac disease.Funding Kanyos Bio.Copyright (c) 2023 Elsevier Ltd.

Immunobridging is an important methodology that can be used to extrapolate vaccine efficacy estimates to populations not evaluated in clinical studies, and that has been successfully used in developing many vaccines. Dengue, caused by a mosquito-transmitted flavivirus endemic to many tropical and subtropical regions, is traditionally thought of as a pediatric disease but is now a global threat to both children and adults. We bridged immunogenicity data from a phase 3 efficacy study of a tetravalent dengue vaccine (TAK-003), performed in children and adolescents living in endemic areas, with an immunogenicity study in adults in non-endemic areas. Neutralizing antibody responses were comparable in both studies following receipt of a two-dose TAK-003 schedule (months 0 and 3). Similar immune responses were observed across exploratory assessments of additional humoral responses. These data support the potential for clinical efficacy of TAK-003 in adults.

Background Acceptability and tolerance of bowel preparation is critical to overcome patient hesitancy in undergoing colon cancer screening and surveillance colonoscopy. To improve patient experience, a new sports drink-flavored bowel preparation containing polyethylene glycol (PEG) and sulfate salts (FPSS) was developed to provide a similar experience to a commonly used but not United States Food and Drug Administration (FDA) approved PEG and sports drink bowel preparation (PEG-SD), while also achieving improved cleansing efficacy. Methods This FPSS preparation, approved by the FDA in June 2023, was evaluated in a non-randomized Phase 2 study in which 40 patients requiring colonoscopy were prepared with FPSS and 20 with PEG-SD. Results Overall cleansing success was high with FPSS based on unblinded local endoscopist assessment (93%) and blinded central reading (97%), exceeding PEG-SD which achieved success rates of 84% (local read), 74% and 68% (blinded central reads). Similar differences favoring FPSS were seen for excellent preparations and cleansing success by colon segment as rated by local endoscopists. Both preparations were well-tolerated, with 93% of FPSS patients rating their preparation as Tolerable to Very Easy to consume, compared to 100% of PEG-SD. Patients who had previously taken a preparation for colonoscopy found FPSS and PEG-SD better than their prior preparation (73% and 70%, respectively) and nearly all would request their assigned study preparation again in the future. About two thirds of FPSS patients agreed that the preparation tasted similar to a sports drink. Conclusion The new sports drink-like flavored preparation compares favorably to PEG-SD for bowel cleansing efficacy while achieving similar patient satisfaction. The study was registered at www.clinicaltrials.gov (NCT03328507) on 01/11/2017.

ImportanceCurrent data identifying COVID-19 risk factors lack standardized outcomes and insufficiently control for confounders.ObjectiveTo identify risk factors associated with COVID-19, severe COVID-19, and SARS-CoV-2 infection.Design, Setting, and ParticipantsThis secondary cross-protocol analysis included 4 multicenter, international, randomized, blinded, placebo-controlled, COVID-19 vaccine efficacy trials with harmonized protocols established by the COVID-19 Prevention Network. Individual-level data from participants randomized to receive placebo within each trial were combined and analyzed. Enrollment began July 2020 and the last data cutoff was in July 2021. Participants included adults in stable health, at risk for SARS-CoV-2, and assigned to the placebo group within each vaccine trial. Data were analyzed from April 2022 to February 2023.ExposuresComorbid conditions, demographic factors, and SARS-CoV-2 exposure risk at the time of enrollment.Main Outcomes and MeasuresCoprimary outcomes were COVID-19 and severe COVID-19. Multivariate Cox proportional regression models estimated adjusted hazard ratios (aHRs) and 95% CIs for baseline covariates, accounting for trial, region, and calendar time. Secondary outcomes included severe COVID-19 among people with COVID-19, subclinical SARS-CoV-2 infection, and SARS-CoV-2 infection.ResultsA total of 57 692 participants (median [range] age, 51 [18-95] years; 11 720 participants [20.3%] aged ≥65 years; 31 058 participants [53.8%] assigned male at birth) were included. The analysis population included 3270 American Indian or Alaska Native participants (5.7%), 7849 Black or African American participants (13.6%), 17 678 Hispanic or Latino participants (30.6%), and 40 745 White participants (70.6%). Annualized incidence was 13.9% (95% CI, 13.3%-14.4%) for COVID-19 and 2.0% (95% CI, 1.8%-2.2%) for severe COVID-19. Factors associated with increased rates of COVID-19 included workplace exposure (high vs low: aHR, 1.35 [95% CI, 1.16-1.58]; medium vs low: aHR, 1.41 [95% CI, 1.21-1.65]; P < .001) and living condition risk (very high vs low risk: aHR, 1.41 [95% CI, 1.21-1.66]; medium vs low risk: aHR, 1.19 [95% CI, 1.08-1.32]; P < .001). Factors associated with decreased rates of COVID-19 included previous SARS-CoV-2 infection (aHR, 0.13 [95% CI, 0.09-0.19]; P < .001), age 65 years or older (aHR vs age <65 years, 0.57 [95% CI, 0.50-0.64]; P < .001) and Black or African American race (aHR vs White race, 0.78 [95% CI, 0.67-0.91]; P = .002). Factors associated with increased rates of severe COVID-19 included race (American Indian or Alaska Native vs White: aHR, 2.61 [95% CI, 1.85-3.69]; multiracial vs White: aHR, 2.19 [95% CI, 1.50-3.20]; P < .001), diabetes (aHR, 1.54 [95% CI, 1.14-2.08]; P = .005) and at least 2 comorbidities (aHR vs none, 1.39 [95% CI, 1.09-1.76]; P = .008). In analyses restricted to participants who contracted COVID-19, increased severe COVID-19 rates were associated with age 65 years or older (aHR vs <65 years, 1.75 [95% CI, 1.32-2.31]; P < .001), race (American Indian or Alaska Native vs White: aHR, 1.98 [95% CI, 1.38-2.83]; Black or African American vs White: aHR, 1.49 [95% CI, 1.03-2.14]; multiracial: aHR, 1.81 [95% CI, 1.21-2.69]; overall P = .001), body mass index (aHR per 1-unit increase, 1.03 [95% CI, 1.01-1.04]; P = .001), and diabetes (aHR, 1.85 [95% CI, 1.37-2.49]; P < .001). Previous SARS-CoV-2 infection was associated with decreased severe COVID-19 rates (aHR, 0.04 [95% CI, 0.01-0.14]; P < .001).Conclusions and RelevanceIn this secondary cross-protocol analysis of 4 randomized clinical trials, exposure and demographic factors had the strongest associations with outcomes; results could inform mitigation strategies for SARS-CoV-2 and viruses with comparable epidemiological characteristics.

BACKGROUND:We conducted a trial to demonstrate immunogenic equivalence of three consecutive manufacturing lots of Takeda's tetravalent dengue vaccine candidate, TAK-003, and further assessed its safety and reactogenicity. METHODS:Healthy US adults (n = 923) randomized 2:2:2:1 to four groups received two doses of one of three TAK-003 lots or placebo on Days 0 and 90, with follow-up to Day 270. Primary endpoint evaluated lot-to-lot equivalence of geometric mean neutralizing titers at Day 120 against each of 4 dengue serotypes in baseline seronegative participants. Solicited local and systemic, and unsolicited adverse events (AEs) were assessed for 7, 14 and 28 days after each dose, respectively. Serious AEs (SAE) were monitored throughout the study. RESULTS:Eight of 12 prespecified equivalence comparisons were met in the per-protocol set but failed marginally in the other 4 mainly due to loss of statistical power following higher than anticipated baseline seropositivity and drop-out rates. All three TAK-003 lots elicited high rates of tetravalent dengue seropositivity (96.7 %, 93.0 % and 97.5 % at Day 120; 91.0 %, 80.5 % and 85.7 % at Day 270) and had similar reactogenicity profiles with no vaccine-related SAEs. CONCLUSIONS:The three lots of TAK-003 were immunogenic for all four dengue serotypes and well tolerated in healthy adults. Despite not meeting all equivalence comparisons, no major differences were observed between lots and the data support acceptable consistency of the manufacturing process.

Dengue is caused by a mosquito-transmitted flavivirus. The disease is now endemic to many tropical and subtropical regions, manifesting as approximately 96 million symptomatic cases of dengue each year. Clinical trials have shown TAK-003 (Qdenga®), a live attenuated dengue tetravalent vaccine, to be well-tolerated, immunogenic, and efficacious in adults with no prior exposure to dengue virus infection living in non-endemic regions, as well as in adults and children living in dengue-endemic areas. This open-label, single-arm phase 3 trial (NCT03771963) was conducted in two dengue non-endemic areas of the USA, and it evaluated the immunogenicity and safety of naturally-aged TAK-003 administered to adult participants. Overall, the immunogenicity data from this trial are consistent with those reported from other TAK-003 phase 2 and 3 trials, and the safety data are consistent with the broader integrated safety data analysis. The data show that naturally-aged TAK-003 had a well-tolerated reactogenicity and adverse events profile when administered in the second half of its clinical 24-month shelf-life and that it still elicited an immune response that persisted up to 6 months after the second dose against all four dengue serotypes, with no important safety risks identified during the trial.

Background Celecoxib-tramadol co-crystal (CTC) is a first-in-class analgesic co-crystal of celecoxib and racemic tramadol with an improved pharmacologic profile, conferred by the co-crystal structure, compared with its active constituents administered alone/concomitantly. Aim We evaluated CTC in moderate-to-severe acute postoperative pain. Materials and Methods This randomized, double-blind, factorial, active- and placebo-controlled phase 3 trial (NCT03108482) was conducted at 6 US clinical research centers. Adults with moderate-to-severe acute pain following bunionectomy with osteotomy were randomized to oral CTC (200 mg [112 mg celecoxib/88 mg rac-tramadol hydrochloride] every 12 h), tramadol (50 mg every 6 h), celecoxib (100 mg every 12 h), or placebo for 48 h. Patients, investigators, and personnel were blinded to assignment. The primary endpoint was the 0-48 h sum of pain intensity differences (SPID0-48) in all randomized patients. Pain intensity was assessed on a 0-10 numerical rating scale (NRS). Safety was analyzed in patients who received study medication. Funded by ESTEVE Pharmaceuticals. Results In 2017 (March to November), 1323 patients were screened and 637 randomized to CTC (n = 184), tramadol (n = 183), celecoxib (n = 181), or placebo (n = 89). Mean baseline NRS was 6.7 in all active groups. CTC had a significantly greater effect on SPID0-48 (least-squares mean: -139.1 [95% confidence interval: -151.8, -126.5]) than tramadol (-109.1 [-121.7, -96.4]; p < 0.001), celecoxib (-103.7 [-116.4, -91.0]; p < 0.001), or placebo (-74.6 [-92.5, -56.6]; p < 0.001). Total treatment-emergent adverse events (TEAEs) were 358 for CTC and 394 for tramadol. Drug-related TEAEs occurred in 37.7% patients in the CTC group, compared with 48.6% in the tramadol group. There were no serious TEAEs/deaths. Conclusion CTC provided greater analgesia than comparable daily doses of tramadol and celecoxib, with similar tolerability to tramadol. CTC is approved in the United States.

Lorlatinib is approved (100 mg once daily [QD]) for the treatment of patients with anaplastic lymphoma kinase- (ALK) positive metastatic non-small cell lung cancer. This study evaluated the impact of varying degrees of renal impairment on the safety and pharmacokinetics of lorlatinib. Participants were assigned to mild, moderate, and severe renal impairment groups and to a matching normal renal function group based on absolute estimated glomerular filtration rate (eGFR, based on the Modification of Diet in Renal Disease equation and adjusted for body surface area [BSA]) and were evaluated for pharmacokinetics and safety. A total of 29 participants (5 with severe renal impairment; 8 each with moderate and mild impairment and normal renal function) were enrolled and received a single dose of lorlatinib 100 mg. One of the participants with severe renal impairment had end-stage renal disease with a baseline absolute eGFR of 10.3 mL/min. No serious adverse events (AEs) were reported. Eighteen AEs, all mild or moderate in severity, were reported by 12 participants (5, 2, 4, and 1 in the normal, mild, moderate, and severe groups, respectively). Area under the plasma concentration–time profile from time zero extrapolated to infinity (AUCinf) for lorlatinib was increased by 4%, 19%, and 41% in the mild, moderate, and severe renal impairment groups, respectively, compared with the normal renal function cohort. Lorlatinib 100 mg was well tolerated. As participants with mild and moderate renal impairment did not experience clinically meaningful increases in lorlatinib exposure, no lorlatinib dose adjustment is recommended in these populations. Patients with severe renal impairment are recommended to reduce the starting dose of lorlatinib from 100 mg QD to 75 mg QD. NCT03542305 (available May 31, 2018 on clinicaltrials.gov)

Purpose: Olpasiran, an N-acetyl galactosamine- conjugated, hepatocyte-targeted, small interfering RNA, is being developed to reduce plasma lipoprotein (Lp)-(a) concentration by directly targeting the LPA gene. This study evaluated the pharmacokinetics, pharmacodynamics, and tolerability of a single SC injection of olpasiran in healthy, Japanese and non -Japanese participants. Methods: In this Phase I, open-label, parallel-design study, Japanese participants were randomized in a 1:1:1:1 ratio to receive a single 3, 9, 75, or 225 mg dose of olpasiran. Non-Japanese participants received a single 75 mg dose of olpasiran. The primary end points were pharmacokinetic parameters, including Cmax, AUC inf, tmax, and t 1/2 . Tolerability and change in Lp(a) concentration were also assessed.Findings: A total of 27 enrolled participants had a mean (SD) age of 48.0 (12.5) years. Olpasiran Cmax and AUCinf were increased in an approximately dose -proportional manner in the Japanese groups. Mean (SD) Cmax values were 242 (121.0) and 144 (71.3) ng/mL, and mean (SD) AUCinf values were 3550 (592.0) and 2620 (917.0) h middotng/mL, in the Japanese and non-Japanese groups, respectively, given 75 mg of olpasiran. Median tmax ranged from 3.0 to 9.0 hours and mean (SD) t 1/2 ranged from 4.0 (0.3) to 6.9 (1.6) hours across all groups. The maximal Lp(a) reduction occurred at day 57, with mean (SD) Lp(a) percentage reductions from baseline ranging from 56.0% (21.0%) to 99.0% (0.2%). A reductions in Lp(a) was observed as early as day 4. All adverse events were mild in severity, with no serious or fatal adverse events. No clinically important changes in tolerability-related laboratory analytes or vital signs were observed. Implications: In this population of healthy Japanese participants, dose-proportional increases in exposure and reduced Lp(a) in a dose-dependent manner were found with single 3, 9, 75, and 225 mg doses of olpasiran. The magnitude and durability of Lp(a) reductions were similar between the Japanese and non -Japanese groups. Olpasiran was well tolerated, with no clinically important adverse events or laboratory or vital sign abnormalities. (Clin Ther. 2022;44:1237- 1247.) (c) 2022 Amgen Inc. Published by Elsevier Inc.

AMG 986 is a novel apelin receptor (APJ) agonist that improves cardiac contractility in animal models without adversely impacting hemodynamics. This phase 1b study evaluated the safety/tolerability, pharmacokinetics, and pharmacodynamics of AMG 986 in healthy subjects and patients with heart failure (HF). Healthy adults (Parts A/B) and HF patients (Part C) aged 18–85 years were randomized 3:1 to single-dose oral/IV AMG 986 or placebo (Part A); multiple-dose oral/IV AMG 986 or placebo (Part B); or escalating-dose oral AMG 986 or placebo (Part C). Primary endpoint: treatment-emergent adverse events, laboratory values/vital signs/ECGs; others included AMG 986 pharmacokinetics, left ventricular (LV) function. Overall, 182 subjects were randomized (AMG 986/healthy: n = 116, placebo, n = 38; AMG 986/HF: n = 20, placebo, n = 8). AMG 986 had acceptable safety profile; no clinically significant dose-related impact on safety parameters up to 650 mg/day was observed. AMG 986 exposures increased nonlinearly with increasing doses; minimal accumulation was observed. In HF with reduced ejection fraction patients, there were numerical increases in percent changes from baseline in LV ejection fraction and stroke volume by volumetric assessment with AMG 986 vs placebo (stroke volume increase not recapitulated by Doppler). In healthy subjects and HF patients, short-term AMG 986 treatment was well tolerated. Consistent with this observation, clinically meaningful pharmacodynamic effects in HF patients were not observed. Changes in ejection fraction and stroke volume in HF patients suggest additional studies may be needed to better define the clinical utility and optimal dosing for this molecule.

Background: Remimazolam is a new benzodiazepine for procedural sedation and general anaesthesia. The aim of this study was to characterise its pharmacokinetic properties and safety in renally and hepatically impaired subjects. Methods: Two separate trials were conducted in patients with hepatic (n=11) or renal impairment (n=11) compared with matched healthy subjects (n=9 and n=12, respectively). The hepatic impairment trial was an open-label adaptive 'Reduced Design' trial, using a single bolus of remimazolam 0.1 mg kg(-1) i.v., whereas the renal impairment trial was an open-label trial of a single bolus dose of remimazolam 1.5 mg i.v. Remimazolam plasma concentrations over time were analysed by population pharmacokinetic modelling. Results: Remimazolam pharmacokinetic properties were adequately described by a three-compartment, recirculatory model. Exposure in subjects with severe hepatic impairment was 38.1% higher (i.e. clearance was 38.1% lower) compared with healthy volunteers. This increase caused a slightly delayed recovery (8.0 min for healthy, 12.1 min for moderate, and 16.7 min for severe hepatic impairment). With renal impairment, plasma clearance was comparable with that measured in healthy subjects. Simulations of C-max after a bolus dose of 10 mg showed no relevant impact of hepatic or renal impairment. The overall incidence of adverse events was low, and all adverse events were mild. Conclusions: As C-max after a remimazolam bolus i.v. was not affected by hepatic or renal impairment, no dose adjustments are required. No unexpected adverse events related to remimazolam were seen in subjects with renal or hepatic impairment.

BACKGROUND AND AIMS: Celiac disease (CeD) is an immune-mediated disorder triggered by the ingestion of gluten. Despite adhering to a gluten-free diet (the only management option available to patients with CeD), many patients continue to experience symptoms and intestinal injury. Degradation of immunogenic fractions of gluten peptides in the stomach has been proposed as an approach to reduce toxicity of ingested gluten; however, no enzymes evaluated to date have demonstrated sufficient gluten degradation in complex meals. TAK-062 is a novel, computationally designed endopeptidase under development for the treatment of patients with CeD. METHODS: Pharmacokinetics, safety, and tolerability of TAK-062 100-900 mg were evaluated in a phase I dose escalation study in healthy participants and patients with CeD. Gluten degradation by TAK-062 was evaluated under simulated gastric conditions in vitro and in healthy participants in the phase I study, with and without pretreatment with a proton pump inhibitor. Residual gluten (collected through gastric aspiration in the phase I study) was quantified using R5 and G12 monoclonal antibody enzyme-linked immunosorbent assays. RESULTS: In vitro, TAK-062 degraded more than 99% of gluten (3 g and 9 g) within 10 minutes. In the phase I study, administration of TAK-062 was well tolerated and resulted in a median gluten degradation ranging from 97% to more than 99% in complex meals containing 1-6 g gluten at 20-65 minutes postdose. CONCLUSIONS: TAK-062 is well tolerated and rapidly and effectively degrades large amounts of gluten, supporting the development of this novel enzyme as an oral therapeutic for patients with CeD.

Cenerimod is a sphingosine‐1‐phosphate 1 receptor (S1P1R) modulator in phase II development for treatment of systemic lupus erythematosus. Its pharmacokinetics (PKs), pharmacodynamics (PDs), as well as safety and tolerability were investigated in white and Asian subjects to allow for recruitment of Asian patients in future studies. A randomized, double‐blind, placebo‐controlled parallel‐group study was performed in 20 healthy male subjects (n = 10 per ethnicity). A single, oral dose of 4 mg cenerimod or placebo (ratio 8:2) was administered under fasted conditions. The PKs of cenerimod were similar in white and Asian subjects indicated by geometric mean ratios (90% confidence interval) of 0.99 (0.80–1.21) for maximum plasma concentration, 0.96 (0.75–1.24) for area under the plasma concentration‐time curve from 0 to infinity, and 1.04 (0.86–1.25) for terminal half‐life. Accordingly, the extent and time course of reduction in lymphocyte count (as PD biomarker) were also similar in white and Asian subjects as compared with placebo. As observed for other S1PR modulators, a transient mean (SD) heart rate reduction in white (15.1 (14.8) bpm) and Asian (11.8 (6.16) bpm) subjects was observed following administration of cenerimod. The drug was safe and well‐tolerated indicated by occurrence of a single adverse event of chemical conjunctivitis in a white subject that was not suspected as study drug related. In conclusion, the determined absence of any relevant PK or PD differences supports using the same doses of cenerimod in white and Asian patients in upcoming late‐phase studies.

ResultsWe identified 49,811 individuals with celiac disease and 246,419 controls with no prior SBA or small intestinal carcinoid.During a median follow-up time of 12.5 years, 46 (0.09%) of celiac individuals were diagnosed with later SBA compared to 43 (0.02%) of controls.Corresponding number for carcinoids were seven (0.014%) for celiac and 38 (0.015%) for controls.The median time between celiac and SBA diagnoses was 2.7 years (7 cases identified same date, an additional 10 cases during the first year, 19 in-between 1-5 years and 18 cases >5 years after celiac diagnosis).The HR for SBA was 5.32 (95%CI= 3.51-8.06)and for carcinoids HR=0.92 (95%CI=0.41-2.05);this corresponds to one extra case of SBA for every 1,346 celiac patients followed for 10 years or equally 7.5 extra cases (9.2 vs expected 1.7) per 10,000 patients followed for 10 years.The HR for SBA excluding the first year of follow-up was 3.36 (2.10-5.38).Conclusion Though the absolute risk of SBA in people with celiac disease in Sweden was low at 0.09%, this represents a >5 fold increased risk compared to the general population.The risk of carcinoids was not increased.
