Article

Author: Zhang, Xinyue ; Zheng, Yuandong ; Yuan, Yali ; Yang, Ying ; Diao, Xingxing ; Yang, Chen ; Xiu, Jin ; Lu, Ming ; Liu, Donghui ; Hu, Pingsheng

Linaprazan (AZD0865, TX07) is one of potassium-competitive acid blockers. However, linaprazan is rapidly excreted from the body, shortening its acid inhibition property. Linaprazan glurate (X842) is a prodrug of linaprazan with a prolonged inhibitory effect on gastric acid secretion. Linaprazan glurate has entered clinical trials, but few studies have reported its metabolism in non-clinical and clinical settings. In this study, we studied the pharmacokinetics, tissue distribution, mass balance, and metabolism of linaprazan glurate in rats after a single oral dose of 2.4 mg/kg (100 µCi/kg) [¹⁴C]linaprazan glurate. The results demonstrated that linaprazan glurate was mainly excreted via feces in rats with 70.48% of the dose over 168 h. The plasma AUC₀_-_∞ of linaprazan glurate in female rats was 2 times higher than that in male rats. Drug-related substances were mainly concentrated in the stomach, eyes, liver, small intestine, and large intestine after administration. In blood, drug-related substances were mostly distributed into plasma instead of hemocytes. In total, 13 metabolites were detected in rat plasma, urine, feces, and bile. M150 (2,6-dimethylbenzoic acid) was the predominant metabolite in plasma, accounting for 80.65% and 67.65% of AUC_0-24_h in male and female rats, respectively. Based on the structures, linaprazan glurate was mainly hydrolyzed into linaprazan, followed by a series of oxidation, dehydrogenation, and glucuronidation in rats. Besides, CES2 is the main metabolic enzyme involved in the hydrolysis of linaprazan glurate to linaprazan.

Design, Synthesis and Pharmacological Evaluation of Novel Imidazopyridine Analogues as Proton Pump Antagonist

Author: Patil, Kiran D. ; Patil, Avinash V. ; Sonawane, Ravindra S.

A series of novel imidazopyridine derivatives as proton pump inhibitors was designed with compounds of CID data base and explored considering AZD0865 as standard. Many compounds were identified and docked in proton pump ATPase pocket (PDB ID: 4ux2). Molecular docking studies revealed that many compounds showed good proton pump ATPase inhibitory activity. The docking poses revealed the interaction of ligands with amino acid. The standard drug AZD0865 had docking score of -7.112302 and displayed interactions with Asn138 and Asp137. A series of novel imidazopyridine derivatives as proton pump inhibitors were docked, synthesized and characterized by IR, NMR, CHN and MS spectral analysis. The target imidazopyridines were prepared from substituted 2-aminonicotinic acid and 2-bromo-1-substituted ethanone. in vitro Studies explained that few compounds exhibited moderate to good proton pump ATPase inhibitory activity in comparison with the reference drugs i.e. AZD0865. Compounds 11 and 12 shown higher activities with the IC50 4.3. Compounds 1, 4, 6, 7, 8, 10 and 13 showed weak anti-ulcer activity with its IC50 5.2, 5.8, 5.5, 5.1, 4.9, 4.6 and 5.9 and positive control AZD0865 shown IC50 2.0.

The purpose of the present study was to characterize current biopharmaceutics modeling and simulation software regarding the prediction of the fraction of a dose absorbed (Fa) in humans. As commercial software products, GastroPlus™ and Simcyp® were used. In addition, the gastrointestinal unified theoretical framework, a simple and publicly accessible model, was used as a benchmark. The Fa prediction characteristics for a total of 96 clinical Fa data of 27 model drugs were systematically evaluated using the default settings of each software product. The molecular weight, dissociation constant, octanol-water partition coefficient, solubility in biorelevant media, dose, and particle size of model drugs were used as input data. Although the same input parameters were used, GastroPlus™, Simcyp®, and the gastrointestinal unified theoretical framework showed different Fa prediction characteristics depending on the rate-limiting steps of oral drug absorption. The results of the present study would be of great help for the overall progression of physiologically based absorption models.

Cinclus Pharma agrees on pediatric study plan with FDA

Cinclus Pharma, a clinical-stage pharmaceutical company developing molecules for the treatment of acid-related diseases, today announces that it has reached an agreement with the US Food and Drug Administration (FDA) on the company’s initial Pediatric Study Plan (iPSP). The regulatory agreement on a pediatric study plan is a prerequisite for market approval of a new medicine for adult patients, such as linaprazan glurate. It also provides an opportunity for an expanded approval for use in children. "The agreement on our pediatric study plan with the FDA is a prerequisite for market approval in the US, so it’s really a milestone. Now that we have agreed with both the EMA and the FDA, we have taken an important step towards making linaprazan glurate available to patients, thereby fulfilling a large unmet need. Furthermore, an approved pediatric indication would significantly increase the target population for linaprazan glurate,” said Christer Ahlberg, CEO of Cinclus Pharma. The company’s agreed iPSP mainly includes a clinical efficacy and safety trial where approximately 100 pediatric patients will be treated with linaprazan glurate on the same treatment schedule as in the company’s phase III trials in adult eGERD patients. The study plan is essentially the same as Cinclus Pharma recently agreed with the European Medicines Agency (EMAs) Pediatric Committee (PDCO). A regulatory agreement of a pediatric study plan must be obtained before a sponsor may submit a Marketing Authorization Application for approval to commercialize a new medicine for adult patients. Cinclus Pharma submitted its proposed iPSP to FDA in December 2023 and has been going through the regulatory review processes since then. The company’s agreed iPSP includes a deferral under which the pediatric efficacy and safety trial is anticipated to be undertaken after a Marketing Authorization Application has been submitted.

Cinclus Pharma agrees on Pediatric Investigation Plan (PIP) with EMA

Cinclus Pharma, a clinical-stage pharmaceutical company developing molecules for the treatment of acid-related diseases, today announces that it has reached an agreement with the European Medicines Agency’s (EMA) Paediatric Commmittee (PDCO) on the company’s Pediatric Investigation Plan (PIP). The regulatory agreement on a pediatric study plan is a pre-requisite for marketing approval of a new medicine for adult patients, such as linaprazan glurate. It also provides an opportunity for an expanded approval for use in children. "It is incredibly satisfying that our pediatric study plan has been agreed. It is a prerequisite for market approval in the EU, so it’s really a milestone. In addition, an approved pediatric indication would of course also significantly increase our target population,” said Christer Ahlberg, CEO of Cinclus Pharma. The company’s agreed PIP mainly includes a clinical efficacy and safety trial where approximately 100 pediatric patients will be treated with linaprazan glurate on the same treatment schedule as in the company’s phase III trials in adult eGERD patients. When a new medicine is developed for adult patients, that medicine must also be tested for potential application to pediatric patients. The sponsor must develop an overall plan to select the specific form or stage of the disease to be treated, to adapt the dosing and administration of the medicine for pediatric physiology, and to evaluate the safety and efficacy of the medicine in pediatric patients. A regulatory agreement of a pediatric study plan must be obtained before a sponsor may submit a Marketing Authorization Application for approval to commercialize a new medicine for adult patients. Cinclus Pharma submitted its proposed PIP to EMA in December 2023 and has been going through the regulatory review processes since then.
