Filter by:This is a Phase I single center, open-label, non-randomized study in healthy male subjects, designed to evaluate the mass balance recovery, PK, metabolism and absolute bioavailability of single oral doses of PCO371. It is planned to enroll 12 subjects, with 6 subjects in each of 2 study parts. Subjects in Part 1 will receive a single oral dose of [14C]PCO371 Oral Solution. Subjects in Part 2 will receive a single oral dose of PCO371 capsules, followed by a single intravenous infusion of [14C]PCO371 Solution for Infusion over 10 min, starting 2 h post-oral dose. The study parts may be dosed in any order for logistical reasons (e.g. Part 2 may be dosed before Part 1). No subject will be permitted to take part in both study parts.
Niclosamide is a well-established substance that is a promising candidate for a repurposing approach to treat COVID-19. Niclosamide is currently marketed as a chewing tablet for the treatment of intestinal worm infections. The marketed formulation is optimized for minimal drug substance absorption. A niclosamide solution has been developed that is expected to release the drug substance more readily and more reproducibly. Camostat is approved for oral treatment of chronic pancreatitis and reflux oesophagitis in Japan. Camostat has been shown to effectively block viral replication in a SARS-CoV-2 animal model. Since the mechanisms of actions are different, it was hypothesized that a combination of both substances might have an additive or even synergistic effect in the treatment of COVID-19 patients. This 3-part study is designed to investigate (1) safety and pharmacokinetics of single ascending doses of the new niclosamide solution after fasted and fed conditions, (2) the relative bioavailability of the niclosamide solution compared to the chewing tablet, and (3) safety and pharmacokinetics of the combination of niclosamide solution and camostat after multiple doses in healthy volunteers.
The aim of the study is to investigate the safety of GH001 (containing 5-methoxy-dimethyltryptamine; 5-MeO-DMT), and its dose-related psychoactive effects in healthy volunteers. The study will evaluate single, ascending doses of GH001 in Part A and an individualized dosing regimen of GH001 in Part B.
The goal of the present study is to confirm in humans the in-vivo bioconversion of a Prodrug (PRX-P4-003) to (-)-fencamfamine (FCF) the active moiety when orally administered as a single microdose. A second component of the study will evaluate effect of food on pharmacokinetics of PRX-P4-003.
The primary objective of this study is to assess the total lung deposition of radiolabelled S-770108 inhalation powder formulation after each of two separate single inhaled doses in healthy adult participants at two different target peak inspiratory flow rates (PIFRs)
The purpose of this study is to determine the absorption, metabolism, and excretion of [14C]-TBPM-PI-HBr and to characterize and determine the metabolites present in plasma, urine, and where possible, feces in healthy male subjects following a single oral administration.
Ultrasonic scalers have been shown effective in removing subgingival calculus. However, it may cause alteration to the tooth surface as well as discomfort to patients. Advances in scaler tip designs may reduce these effects. Limited studies have investigated the influence of scaler tip designs on tooth surface and patients' comfort. This study aimed to evaluate the influence of scaler tip designs on patients' pain perception.
The planned study is to determine the safety and pharmacokinetic properties of CPL207280 compound after single and multiple (two weeks) administration in healthy volunteers.
This Phase 1 study is designed to determine the safety, tolerability and pharmacokinetics of PN-235 in healthy volunteers. The study will be conducted in three parts: Part 1 is a single ascending dose study, Part 2 is multiple ascending dose study, and Part 3 is a randomized, crossover solid dose comparison and effect of food study.
A Phase 1 Open-label, Non-randomized, Single Ascending Dose Escalation Study To Evaluate The Pharmacokinetics, Safety, And Tolerability Of A Ralinepag Extended Release (XR) Tablet Formulation In Healthy Chinese Subjects.
