Filter by:Medicines that may have different names or be made in different ways but have the same effect on the body are called bioequivalent. The purpose of this study is to learn about the bioequivalence of nirmatrelvir plus ritonavir after taking 2 different combination tablet forms by mouth. These combination tablets are compared to the tablet formulation that is already in the market. This study will be done under fasted conditions in healthy adult participants. This study is seeking participants who are: - Male and non-pregnant female participants aged 18 years and above. - with a body weight of more than 50 kilograms and Body Mass Index (BMI) between 16 to 32 kilograms per meter squared. - are healthy as confirmed by medical history, physical examination, laboratory tests. The study will also look at the safety and tolerability of nirmatrelvir plus ritonavir combination tablet and marketed tablet formulations in healthy adult participants. The study will consist of 4 treatments: Treatment A: Single oral dose of nirmatrelvir plus ritonavir 150 (1 × 150)/100 milligrams marketed tablets under fasted conditions (Reference 1) Treatment B (low dose strength): Single oral dose of nirmatrelvir plus ritonavir 150/100 milligrams (2 × [75/50 milligrams]) combination tablets under fasted conditions (Test 1) Treatment C: Single oral dose of nirmatrelvir/ritonavir 300 (2 × 150)/100 milligrams marketed tablets under fasted conditions (Reference 2) Treatment D (high dose strength): Single oral dose of nirmatrelvir/ritonavir 300/100 milligrams (2 × [150/50 milligrams]) combination tablets under fasted conditions (Test 2) All treatments will be given under fasted conditions. Fasted condition means the participants would not have had anything to eat before taking the medicines. Around 28 participants will be enrolled in the study. Healthy participants will be tested to see if they can be in the study within 28 days before receiving the study medicine. Selected participants will be admitted to the clinical research unit (CRU) one day before receiving the study medicine and will remain in the CRU until discharge after completing all the treatment periods. On Day 1 of each period, participants will be given a single dose of study medicine nirmatrelvir/ritonavir 300/100 mg or 150/100 mg by mouth by chance. Study medicine will be given with approximately 240 milliliters of room temperature water under fasted conditions (overnight fast of at least 10 hours and no food until 4 hours after receiving the study medicine). Blood samples will be collected at different times of the day up to 48 hours after taking the study medicine. Participants will be discharged from the CRU on Day 3 of Period 4, after all the study related procedures have been completed. A follow-up call will be made to participants around 28 to 35 days from receiving the final dose of the study medicine. The study will look at the experiences of participants receiving the study medicine. This will help to understand if the study medicine is safe and effective.
The purpose of this study is to compare three finished products of PF-06954522 in terms of the uptake into the blood stream. This study is seeking participants who are: - Healthy male or female participants aged 18 years or older. All participants in this study will receive PF-06954522 once by mouth. The participants may receive different tablets by mouth for PF-06954522. The study will compare experiences of people receiving three different products of PF-06954522. This will help understand how much PF-06954522 is taken up into the blood for each product given. Participants will take part into the study for about 77 days. During this time participants will have to stay onsite for 21 days. There will be one follow up (by telephone) study visit.
The purpose of this study is to learn how a certain amount of [14C] PF-06821497 is taken up into the bloodstream and removed from the body. The study is seeking participants who are: - Males aged 18 years or older. - Are confirmed to be healthy after performing some medical and physical tests. - Weigh more than 50 kilograms and have a body mass index of 16 to 32 kg per meter squared. The study consists of two parts. In part one, all participants will receive one full dose of [14C]PF-06821497 by mouth. Part two will begin at least 14 days after the dose in part one. In part two participants will receive one full dose of PF-06821497 by mouth and one small dose of [14C]PF-06821497 by intravenous (IV) infusion. IV infusion will be directly injected into the veins. To understand how the medicine is processed in the body, samples of blood, urine, and feces will be collected after each dose is given. This will help understand: - How much PF-06821497 is taken up into the bloodstream when taken by mouth compared to the dose given by IV - How the body removes it from the bloodstream. Participants will take part in the study for about 11 weeks, including the initial evaluation and follow-up periods.
The purpose of this study is to evaluate the drug interaction between povorcitinib and the oral contraceptive levonorgestrel/ethinyl estradiol in healthy adult females.
The goal of this clinical trial is to investigate the effects of resistance training with hydrolyzed collagen ingestion on changes in muscle and tendon adaptation in healthy young men and women. The main questions it aims to answer are: - Does resistance training with hydrolyzed collagen ingestion lead to greater changes in tendon properties than resistance training alone? - Does resistance training with hydrolyzed collagen ingestion lead to greater changes in muscle size than resistance training alone? Participants will be randomly assigned to collagen or placebo groups. Participants will perform resistance training three times per week for 10 weeks and hydrolyzed collagen or maltodextrin will be given to collagen or placebo group respectively immediately before each resistance training session. Also, vitamin C will be given to both groups. Researchers will compare collagen and placebo groups to see if hydrolyzed collagen ingestion with resistance exercise would have beneficial effects on changes in muscle and tendon more than resistance training alone. Therefore, using isokinetic dynamometer and ultrasonography, maximal leg strength, morphological, mechanical, and material properties of the patellar tendon and vastus lateralis muscle size and architecture will be assessed.
The main purpose of this study is to assess the safety, tolerability and pharmacokinetics (PK) of oral AZD6793 in healthy Japanese and Chinese participants.
The primary purpose of this study is to evaluate the potential of gastric pH-dependent drug-drug interaction effect of esomeprazole, a proton pump inhibitor (PPI), on the pharmacokinetics (PK) of emraclidine in healthy adult participants.
This Study is a Randomized, Open-Label, 2-formulation, Single-Dose, 2-Period Crossover Bioequivalence Study with a washout period of 7 days. During each session, the subjects were administered a single dose of 100 mg Olaparib Tablets (Test formulation or reference formulation ) under Fasting conditions or 150mg Olaparib Tablets (Test formulation or reference formulation ) under Fasting and Fed conditions. Venous blood samples were collected at pre-dose (0 h), and up to 72 h post dose. This study was to evaluate the bioequivalence and safety of the test formulation and the reference formulation of Olaparib Tablets in healthy subjects.
The main purpose of this study is to assess the effect of itraconazole on the pharmacokinetic (PK) of baxdrostat.
Tranexamic acid is a well-established treatment for post-partum hemorrhage. This study aims to examine the effect of tranexamic acid administration rates on blood pressure changes over 1 minute compared to 10 minutes in healthy pregnant patients scheduled for cesarean delivery.
