32 Clinical Trials for Various Conditions
The study employs two-sub-studies that share a common placebo arm. The objective of one sub-study is to assess the impact of metformin on pravastatin and chenodeoxycholic acid pharmacokinetics. We hypothesize that metformin represses the bile salt export pump (BSEP) in the liver, which excretes pravastatin and chenodeoxycholic acid from the liver into the bile. The objective of the other sub-study is to assess the impact of polysorbate 80 on valacyclovir, chenodeoxycholic acid, and enalaprilat pharmacokinetics. We hypothesize that polysorbate 80 inhibits uptake transporters in the intestine, which absorb valacyclovir and chenodeoxycholic acid in the gut via the peptide transporter 1 (PepT1) and apical sodium-bile acid transporter (ASBT), respectively. Enalaprilat is passively absorbed but with low permeability, and thus serves as a passive absorption reference.
The study will evaluate bioavailability, pharmacokinetics, safety, and tolerability of budesonide, glycopyrronium and formoterol (BGF) metered dose inhaler (MDI) formulated with 3 different propellants: Propellant 1 (Treatment A \[test\]), Propellant 2 (Treatment B \[test\]) and Hydrofluoroalkane (HFA) (Treatment C \[reference\]).
The purpose of this study is to determine if sodium lauryl sulfate (SLS), a non-drug ingredient commonly added in drug products, affect absorption of drugs that are given together with the ingredient. Investigators want to find out if drug absorption is different in people taking the drug alone compared to people taking the drug with low and high amounts of sodium lauryl sulfate at the same time.
Background: Artificial sweeteners like sucralose are found in many foods and drinks. Sucralose might affect hormones and cause health changes. Objective: To see if sucralose changes how medicines are absorbed and processed, how hormones are secreted, gut bacteria, and how fat cells are metabolized. Eligibility: People ages 18-60 who: * Are black or Hispanic * Weigh more than 110 pounds * Have a body mass index of 25-40 * Do not have a condition that requires drug treatment Design: Participants will be screened with: * Medical history * Physical exam * Blood, heart, and urine tests Participants must not eat or drink anything with artificial sweeteners throughout the study. Over 7 days, Participants will answer questions, and give daily urine samples and 1 stool sample. Participants will repeat these throughout the study. Overnight Visit 1: participants will fast starting the night before. They will get breakfast at the visit. The visit includes: * An IV will be placed in the arm. Participants will get 2 tablets of medicines. Blood will be drawn several times over 24 hours. * A piece of fat tissue may be taken from the abdomen (biopsy). * Participants will have a sweet drink. Blood samples will be taken over 2 hours. Then participants will be randomly assigned to take either a sucralose capsule or placebo. They will take it twice a day for 2 weeks. They will complete two 24-hour food diaries. Overnight Visit 2 repeats Visit 1 except the biopsy. Then participants will take the capsules for another 2 weeks. Overnight Visit 3 repeats Visit 1. Participants may be contacted by phone within 4 weeks after they finish....
The purpose of this study is to evaluate the potential of DFD-06 to suppress the hypothalamic-pituitary-adrenal (HPA) axis when applied twice daily for 15 days.
The investigators' objective is to describe the variability of rifampicin absorption, markers of inflammation and gut damage, intestinal absorptive capacity, and intestinal permeability among HIV-infected volunteers. Rifampicin is the least well absorbed of the first-line anti-tuberculosis drugs. Rifampicin malabsorption is frequently observed in HIV-infected patients with active tuberculosis, but cannot be predicted by patient factors such as CD4+ T cell count, viral load, or the presence of diarrhea. The mechanisms for rifampicin malabsorption in HIV-infected patients are unknown. An understanding of mechanisms for rifampicin malabsorption could eventually lead to new therapeutic targets, with the ultimate goal of improving HIV/tuberculosis treatment outcomes.
Poorly absorbed medications such as furosemide are common and recent experiments suggest that improvement in absorption can occur if these types of medications are consumed with liquids such as milk. The purpose of this study is to evaluate the absorption of furosemide in normal adults when taken with bottled water, milk (Parmalat™ Whole Milk), baby formula (Similac Pro-Advance™), or Ensure Plus™. These results will be used to make models that predict how these liquids will affect drug absorption in children, potentially providing ways to improve medication absorption in children.
The purpose of the study is to assess mass balance, biotransformation, and excretion of BMS-986369 following study drug administration.
The morbidly obese frequently present with mood and anxiety disorders, which are often treated with serotonin reuptake inhibitors (SRI) antidepressant drugs. The investigators hypothesized that gastric bypass surgery would decrease the absorption of SRI. The investigators also wished to determine whether a reduction in SRI levels would increase the likelihood of worsening depressive symptoms.
The purpose of this study is to evaluate sites of gut absorption of BMS-986165 in males
An evaluation of tablet disintegration and absorption and gastric transit of sumatriptan and naproxen sodium from a TREXIMA tablet and eletriptan from a RELPAX 40mg tablet.
In order to meet FDA standards of safety and efficacy reporting for most new drugs, food-effect bioavailability (the impact that the presence of food in the digestive tract has on the rate and extent at which a drug is absorbed into the bloodstream and delivered to the site of action) must be collected. Cystagon™ is an FDA approved drug for the treatment of the rare disease cystinosis that became available in 1994, but there is inadequate knowledge of the food-effect on this drug's bioavailability. This study aims to investigate how food affects the absorption of Cystagon™ into the bloodstream of normal healthy adults.

In this study, the researchers will compare 2 new tablet forms of BAY2731954 with liquid oral forms of BAY2731954. A maximum of 61 healthy volunteers aged 18 to 55 will be asked to participate. The study will have 2 parts. In part 1 researchers want to gather information how the body absorbs, distributes and excretes the drug BAY2731954 given as two different tablet formulations. Participants will take the study drugs on 3 days separated by breaks of at least 3 days between each intake. The duration of this study part will be in total of up to 6 weeks from first screening visit to follow-up visit. In part 2 of the study researchers want to study how the body absorbs, distributes and excretes the drug BAY2731954 given as two different tablet formulations with or without food or as 2 liquid oral formulations. Participants will take the study drugs on 4 days separated by breaks of at least 3 days between each intake. The duration of the second part of study part will be in total of up to 7 weeks from first screening visit to follow-up visit. During the study, researchers will collect blood and urine samples. In addition, doctors will check the participants' overall health. They will also ask the participants if they have any medical problems.
This drug-drug interaction study will evaluate the impact of two different acid reducing agents (from two different drug classes) co-administered with a single dose of telotristat ethyl.
The purpose of this study is to assess the pharmacokinetics (PK), metabolism, routes and extent of elimination, safety and tolerability of a single oral dose of \[14C\] BMS-955176 in healthy male subjects. There is no formal research hypothesis to be statistically tested for this study.
Oxymetazoline is an α-adrenergic agonist that is commonly used as a topical sympathomimetic agent in over-the-counter decongestant sprays. It is used extensively at Nationwide Children's Hospital for surgical procedures to produce vasoconstriction and reduce bleeding. Although there is generally limited vascular absorption, when administered in larger doses, uptake of oxymetazoline can lead to significant systemic hemodynamic effects. The NCH anesthesia department recently reported a case of oxymetazoline induced postoperative hypertension in a three-year-old child following inferior turbinate reduction and adenoidectomy. Current practice at NCH is to soak pledgets with full strength oxymetazoline and insert a varying number of pledgets during surgical procedures or instill oxymetazoline drops into the nose prior to nasotracheal intubation. There is no pediatric data regarding the method of administration and the absorption of oxymetazoline or the dose-response relationship of oxymetazoline serum levels on blood pressure and heart rate. These studies would be the first to determine safe and appropriate doses of oxymetazoline in the pediatric population.
A single 125 mg oral dose of the investigational compound PD-0332991 will be administered alone and after steady-state dosing of tamoxifen to determine if coadministration of tamoxifen alters the plasma pharmacokinetics of PD-0332991 in healthy male volunteers.
The purpose of this study is to determine which of three delivery systems of vaginal diazepam have the best systemic absorption, measured by serum diazepam levels. The three delivery systems are: moistened tablet, suppository or cream. Additionally the study will compare the side effects and absorption of vaginal diazepam with oral diazepam. Vaginal diazepam is used off-label vaginally to relax pelvic floor muscles and reduce pelvic pain caused from pelvic floor dysfunction.
The investigators are developing a new nuclear medicine imaging technique for measuring liquid absorption in the airways that can be applied to screen new medications being developed to treat cystic fibrosis (CF). The investigators believe that the absorption of the small molecule radiopharmaceutical Indium 111-diethylenetriaminepentaacetic acid (In-DTPA) will indicate changes in liquid absorption in the airways and demonstrate whether new CF medications will be effective. In this study the investigators will further develop this technique through testing involving pediatric CF patients and healthy control subjects.
The purpose of this study is to assess the pharmacokinetic interaction of multiple-dose ketoconazole on single-dose YM178 OCAS and the safety and tolerability of YM178 OCAS alone and in combination with ketoconazole in healthy adult volunteers.
This study will examine the effects of formulation on the relative bioavailability of SB-751689 (400 mg) administered to healthy postmenopausal women. Subjects will receive a single oral dose of each formulation, with five formulations of SB-751689 tested in total. Blood samples will be taken up to 24 hours postdose after each dose administration. This study will provide information for future possible formulation development of SB-751689 for Phase III.
This is a single-center, open-label, concentration-ranging study to evaluate the nicotine PK profile and PD effects in healthy adult experienced users of closed tank/cartridge e-cigarettes using four different variants of P4M3 (nicotine concentration of 1.7%, 1.7% with 1.1% lactic acid \[LA\], 3% with 1.1% LA, and 4% with 2% LA) or their own e-cigarettes.
Amorphous solid dispersion (ASD) formulations are increasingly used by the pharmaceutical industry to develop poorly water-soluble drugs into effective oral dosage forms. Examples include the antifungal drug itraconazole, the HIV protease inhibitor combination, lopinavir/ritonavir and the immunosuppressive, tacrolimus. There is potential for significant variation in bioavailability of ASD and thus heightened concern regarding the therapeutic efficacy as generic versions of these poorly water-soluble compounds become approved. The variation in bioavailability is to be expected because of our limited understanding of the precise physical chemistry of drug polymer amorphous solid dispersion formulations.
The primary objective of the study is to evaluate the pharmacokinetic (PK) profiles (rate and amount of nicotine absorbed) after a single use of the THS 2.2 Menthol (mTHS 2.2) compared to a single use of the menthol conventional cigarette (mCC) and nicotine nasal spray (NNS).
Background: - Pomalidomide is a drug that alters the body's immune response. It may help people who have chronic graft-versus-host disease (GvHD). GvHD may appear after a stem cell transplant, when immune cells in the transplant try to attack tissues in the person who received the transplant. GvHD is not easy to treat, and often does not respond to standard treatments. Researchers want to see if pomalidomide is a safe and effective treatment for GvHD. Objectives: - To test the safety and effectiveness of pomalidomide for GvHD that has not responded to standard treatments. Eligibility: - Individuals at least 18 years of age who have GvHD that has not responded to standard treatments. Design: * Participants will be screened with a physical exam and medical history. Blood and urine samples will also be collected. A lung function test and imaging studies will also be given. * Participants will take pomalidomide capsules once a day for 4-week periods called cycles. * Treatment will be monitored with frequent blood tests and imaging studies. Saliva samples and skin and mouth tissue biopsies will also be collected during treatment. * Treatment will continue for six cycles (6 months), unless the GvHD gets worse or side effects are too severe. If the GvHD has improved at the end of the six cycles, participants may be able to continue to take pomalidomide for up to six more cycles.
