114 Clinical Trials for Various Conditions
The proposed study is a quality improvement initiative designed to rigorously evaluate new variations of UCLA Health's proton pump inhibitor (PPI) order panels, building on internal quality improvement efforts to optimize prescribing workflows within the Electronic Health Record (EHR). PPIs are notoriously overprescribed, and the study team has identified that the CareConnect default prescription setting of 90 days with three refills (360 pill days) exceed standard guidelines (in most cases, 60 pill days). It is unclear whether this is the most appropriate workflow. Given that deprescribing PPIs carries minimal risk for most patients, this initiative will assess whether modifying defaulted prescription lengths influences prescribing behavior while ensuring physicians retain full decision-making authority. This evaluation of PPI order panel variations is embedded within UCLA's existing EHR system, ensuring that changes are tested pragmatically within routine workflows. The study aims to determine whether small adjustments to the order panel can better align prescribing patterns with clinical best practices while maintaining physician autonomy.
The central hypothesis of this research study is that perioperative administration of the proton pump inhibitor (PPI) pantoprazole could reduce the development of acute kidney injury (AKI) following cardiac surgery by activation molecular pathways for kidney protection. The investigators propose a single-center, randomized, controlled, single-blinded trial to determine whether perioperative intravenous administration of pantoprazole will reduce the incidence of AKI, some molecules that can be detected the urine, and major adverse kidney events (MAKE) at day 30 postoperatively, compared to famotidine after cardiac surgery. The specific aims of the study will be achieved by randomizing a group of 400 patients to receive pantoprazole (study) or famotidine (control) for 3 days perioperatively. Our study population will include any adult patients (aged over 18 years) scheduled for cardiac surgery requiring a cardiopulmonary bypass machine.
The purpose of this study is to evaluate the effect of food, formulation, and a PPI on the levels of MK-1084 in a person's body over time.
The investigators propose a single-center, randomized, controlled trial to determine whether early initiation of proton pump inhibitor (PPI), pantoprazole, will decrease acute kidney injury (AKI) for trauma patients presenting with hemorrhagic shock compared to routine timing of initiation of PPI. Kidney injury will be assessed by the urinary kidney injury biomarkers, and the incidence, severity and AKI-free days within first week and major adverse kidney events (MAKE) at day 30. The specific aims of the study will be achieved by a cohort of 100 patients to receive either early(study) or routine (control) administration of pantoprazole for 2 days after the initial injury insult.
The primary objective of the study is to evaluate the effects of a proton pump inhibitor (PPI) \[rabeprazole\] on BIIB122 pharmacokinetics (PK) after a single dose in healthy participants. The secondary objective of the study is to evaluate the safety and tolerability of BIIB122, with and without a PPI (rabeprazole), after a single dose in healthy participants.
The purpose of this study is to determine whether perioperative intravenous administration of pantoprazole will improve kidney function parameters following cardiac surgery with cardiopulmonary bypass compared to famotidine and to determine whether perioperative intravenous administration of pantoprazole will decrease the incidence of postoperative Acte Kidney Injury (AKI) and major adverse kidney events (MAKE).
The goal of this clinical trial is to identify the most effective way to take acid-blocking medications to treat stomach ulcers in patients who have undergone gastric bypass surgery. The main questions it aims to answer are: * is taking an acid-blocking medication by opening the capsule and only taking the contents of the capsule (open-capsule) more or less effective than taking the capsule as a whole (intact-capsule) for treating ulcers in patients who have a history of gastric bypass surgery? * does taking the open versus intact medication decrease the number of procedures and complications from untreated ulcers? Participants with ulcers will be instructed to take acid-blocking medications (called proton-pump inhibitors) either by opening the capsule and taking only the contents or by taking the capsule whole. These medications are the gold standard for treatment of stomach ulcers. Participants will be asked to undergo an upper endoscopy (EGD) every 3 months to monitor the healing of the ulcers. Researchers will compare how quickly the ulcers heal depending on which way the medications are taken (opened up or as a whole).
A Phase 1, Open-label, 4-Period, Randomized 6-Sequence Study to Evaluate the Effect of Food and Rabeprazole, a Proton Pump Inhibitor, on the Pharmacokinetics of HMPL-523 in Healthy Volunteers
The purpose of this study is to investigate the impact of the probiotic Lactobacillus rhamnosus (LGG) on proton pump inhibitor (PPI)-induced changes to the microbes that live in the gastrointestinal tract and are passed out in the stool. PPI medicines reduce stomach acid and are commonly used to treat acid reflux disease.
The main purpose of this study is to assess the effect of food on how fast selpercatinib gets into the bloodstream and how long it takes the body to remove it after a high-fat meal, and the effect of a change in gastric pH after multiple doses of omeprazole on how fast selpercatinib gets into the bloodstream and how long it takes the body to remove it when administered under fasted and fed conditions in healthy participants. The study will also evaluate the safety and tolerability of selpercatinib in healthy participants. The study will last up to 33 days excluding the screening period.
The main purpose of this study is to learn about how H2 antagonist (ranitidine) and proton pump inhibitor (PPI) (omeprazole) affect Selpercatinib in healthy participants. Information about safety and tolerability will be collected. The study will last up to about 9 weeks, inclusive of screening period.
The purpose of this study is to prospectively determine the effects of administering proton pump inhibitors (PPIs) following pancreaticoduodenectomy on postoperative outcomes. The findings of this study will help in avoiding the widespread use of PPIs during the immediate postoperative period following pancreatic surgery.
The main purpose of this study is to learn about how food and a PPI (omeprazole) affect LOXO-305 in healthy participants. Participation could last about nine weeks.
A total of 40 patients taking proton pump inhibitors (PPIs) who undergo transjugular intrahepatic portosystemic shunt (TIPS) creation as part of routine clinical care will be randomized in 1:1 fashion to either continue or discontinue their PPIs to determine whether these commonly used gastric acid suppressing agents increase risk of post-TIPS hepatic encephalopathy (HE). Patients will be assessed for symptoms of minimal HE (MHE), using the established psychometric hepatic encephalopathy score (PHES) battery of tests. MHE assessment will be conducted at two timepoints: at baseline prior to randomization and TIPS creation and approximately 4 weeks after randomization and TIPS creation. Stool samples will also be collected at both timepoints to allow characterization of the gastrointestinal (GI) tract microbiome using 16S rRNA sequencing. The pre to post-TIPS change in PHES scores will be compared between patients randomized to continue versus discontinue their PPIs. Quality of life (QOL) will also be assessed. Changes in the GI tract microbiome will be analyzed to determine whether this represents a potential biological mechanism linking PPI use with post-TIPS HE.
The purpose of this is to evaluate the effect of food and the effect of a proton pump inhibitor (rabeprazole) on the pharmacokinetics of fruquintinib.
This study is being conducted to support the clinical development of acalabrutinib in participants who need treatment with proton pump inhibitors while taking acalabrutinib.
This study will be a 2-part, open-label, single-center relative bioavailability, PPI effect, food-effect and particle size effect randomized crossover study of acalabrutinib tablets in healthy subjects (males or females). The study will be divided in 2 study parts; following a review of the safety and Pharmacokinetics (PK) data from Part 1, the study is planned to be continued with Part 2.
This study is being conducted to support the clinical development of acalabrutinib in patients who are unable to swallow capsule and require nasogastric (NG) tube placement.
This longitudinal study tests the hypothesis that obesity affects drug pharmacology of acid suppression medications in children.
This study will enroll participants who have been diagnosed with Eosinophilic Esophagitis (EoE). Upon study enrollment, the participant will begin a proton pump inhibitor (PPI), Omeprazole 20mg twice daily. After taking Omeprazole for four weeks, the participant will have a Transnasal Endoscopy, and biopsies will be taken to determine the histological change. If the biopsies are abnormal, the participant continues Omeprazole and will undergo another endoscopy at eight weeks. The study aims to determine the percentage of children with Eosinophilic Esophagitis who improve with PPI use and to determine the length of time and effectiveness of PPI therapy in the management of EoE. The investigators hypothesize that following the initiation of PPI for treatment of Eosinophilic Esophagitis, biopsies obtained will show decreasing eosinophil counts at four weeks, which is sooner than the previously reported eight-week period.
The purpose of this study is to evaluate the effect of the proton pump inhibitor (PPI) esomeprazole on the single-dose PK of orally administered TAK-906.
Proton pump inhibitors (PPIs) are widely used for the control of gastric ulcer-gastritis, erosive esophagitis (gastroesophageal reflux disease), peptic ulcer disease (duodenal ulcer), and heartburn. Despite their efficacy, their use has been implicated in possibly causing fragility fractures (osteoporosis), hypomagnesemia (magnesium deficiency) and increased risk of chronic kidney disease (CKD). The current trial represents the investigators' ongoing effort to discern whether these complications could be averted by effervescent calcium magnesium citrate (EffCaMgCit).
Proton pump inhibitors (PPIs) are medications used to treat acid-related stomach disorders, such as chronic heartburn. These medications are widely used by Veterans, with over 11 million 30-day prescriptions being filled each year. Though they are highly effective, long-term use of PPIs may be harmful. For this reason, experts recommend that PPIs be stopped in patients who do not have a clear need for these medications. Unfortunately, PPIs continue to be overused. To address this issue, the VA is implementing a national program to de-prescribe (i.e., reduce the dose of, or stop) PPIs. In this study, the investigators will be evaluating this national program by assessing: (a) how successfully the program was implemented; (b) understanding how effective the program was in improving appropriate use of PPIs; and, (c) ensuring no unintended consequences (such as peptic ulcer bleeding) occurred with PPI de-prescribing. This study addresses a potential safety concern for Veterans and aligns with VA's broader goal of de-implementing low-value care.
The objective of this study is to evaluate the safety and efficacy of IW-3718 administered to patients with GERD who continue to have persistent symptoms, such as heartburn and regurgitation, while receiving once-daily (QD), standard dose PPIs.

This is a clinical trial with a cross over design investigating the effect of the proton pump inhibitor omeprazole on fat malabsorption in subjects with cystic fibrosis and pancreatic insufficiency. Participants will be randomized to receive either omeprazole or placebo for 28 days, then cross over and receive omeprazole or placebo for another 28 days. Markers of fat absorption will be measured after each treatment course.
The researchers wish to investigate whether proton pump inhibitors, administered prior to or after surgery, can reduce the incidence and/or severity of difficulty swallowing foods and/or liquids,following anterior cervical surgery.
This pilot study will explore whether treatment of eosinophilic inflammation in the esophagus is associated with an improved distensibility of the esophagus. Furthermore, previous studies of the esophagus using EndoFlip only measured distensibility of the distal esophagus, specifically the distal esophagus and esophagogastric junction. Eosinophilia in EoE has been demonstrated to affect both upper, middle and lower esophagus. The aim is to measure distensibility both proximal and distal, before and after treatment.
to evaluate the effect of the PPI (rabeprazole) on the PK of a potential commercial tablet formulation of palbociclib
The purpose of this study is to measure the amount of study drug present in blood after being administered a generic version of nifedipine extended-release tablets, 60 mg (Valeant Pharmaceuticals, LLC) and brand-name version PROCARDIA XL extended-release tablets, 60 mg (Pfizer Inc.) individually and in presence of stomach acid reducing drug (antacid), omeprazole/sodium bicarbonate capsules, 40 mg/1100 mg (generic) on separate occasions, on an empty stomach. This study also involves administrations of an FDA-cleared capsule, SmartPill™, which will measure stomach acid, prior to each study arm.
