Combination treatment with baclofen and chlorzoxazone (CHZ) is under investigation for the treatment of spinocerebellar ataxia types 1 and 2. Achievement of therapeutic benefit with this combination approach requires that effective concentrations of both agents reach the systemic circulation, and ultimately reach the intended pharmacologic target. This in turn requires understanding of the clinical pharmacokinetic properties of both drugs when administered individually, as well as knowledge of the extent to which the agents might interact when given concurrently. Study Objectives: 1. To evaluate the pharmacokinetic properties of baclofen and CHZ when administered as individual entities at separate times, using customary clinical doses. 2. To compare the pharmacokinetic properties, and assess the bioequivalence, of each drug administered separately compared to administration of the two drugs concurrently. 3. To assess adverse events attributed to the two drugs when administered separately or together.
This is an open-label, randomized, single-dose, three treatment, three-period crossover study comparing the test and reference products under fasted or fed conditions (as applicable). In one period of the study, PrimeC-ER tablets will be administered to subjects following an overnight fast of at least 10 hours. In a second period of the study, PrimeC-ER tablets will be administered to subjects at 30 minutes following the start of a standardized high-fat, high-calorie breakfast that was preceded by an overnight fast of at least 10 hours. In a third period of the study, a single 750 mg dose of ciprofloxacin and a single 200 mg dose of celecoxib will be co-administered to subjects following an overnight fast of at least 10 hours. The order of administration will follow a six-sequence randomization schedule. Blood samples will be collected at pre-dose and at intervals over 48 hours after dosing in each study period. Subjects will be confined at the clinical facility from at least 10.5 hours before dosing until 48 hours after dosing in each study period. The interval between doses will be at least 7 days. Subjects will return to the clinical facility 7 days (± 1 day) after the last study drug administration for an end-of study follow-up visit.
This is a phase 1 single-center study to assess the pharmacokinetics (PK), safety and tolerability of KT07 capsules in healthy adult subjects. This study consists of 2 parts: Part 1 and Part 2. The primary objectives of Part 1 include selection of suitable PK markers for bioanalysis, development and validation of GLP bioanalytical methods for follow-up PK studies, assessment of PK of potential markers following an oral administration of KT07, and provision of PK sampling strategy for Part 2. The primary objective of Part 2 is to evaluate the PK profile following a single dose and multiple doses in healthy adult subjects.
Randomized, double-blind and placebo-controled study to assess the safety, tolerability and pharmacokinetics of single ascending doses of ZX-7101A and its food effect in China healthy adult volunteers. The study is composed of 2 parts. Part 1 is to assess the safety, tolerability and pharmacokinetics of a single ascending doses of ZX-7101A tablet. Part 2 is to assess the food effect on ZX-7101A at a selected dose in a cross-over design.
This is a phase I randomized, placebo-controlled, single site to assess the local and systemic safety of intranasal Q-Griffithsin (Q-GRFT) after 14 doses in approximately 45 adult participants. Participants will be randomized 2:1 (Q-GRFT nasal spray: placebo nasal spray) resulting in 30 participants enrolled into the Q-GRFT arm and 15 participants enrolled into the placebo arm. A clinician will apply two metered doses of Q-GRFT in each nostril (400μl total) of the participant on the day of enrollment. Participants will be monitored in the clinic for 1 hour after administration and return for a 24-hour post dose visit. If safe and acceptable, a second period of daily administration by the participant for 13 days will commence. Safety assessments will be performed at day 7, day 14, and day 28 visits after the initiation of the second period. The expected duration of study participation for each participant will be approximately 6-8 weeks. The primary endpoint is the proportion of participants who experience a related Grade 2 or higher adverse event. Secondary and exploratory endpoints include persistence and systemic absorption of Q-GRFT, acceptability and the impact of Q-GRFT nasal spray on smell.
Identification of renal dysfunction in critically ill children is often delayed due to lack of accurate methods for evaluation of glomerular filtration rate (GFR). The investigators compared GFR measurement by the gold standard technique iohexol plasma clearance with estimated GFR (eGFR) based on selected established formulas incorporating the renal biomarkers creatinine, cystatin C and betatrace protein.
This is a randomized, open label, single-center, single-dose, four-period crossover clinical study to assess the pharmacokinetic profile and safety of a budesonide inhalation solution (AQ001S) compared to a budesonide inhalation suspension (comparator) in healthy volunteers.
This protocol is a Phase 1 open-label study with a primary purpose of evaluating the food effect of a high calorie meal as compared to fasting conditions on the relative bioavailability of oral MDMA capsules in healthy volunteers. In addition, increases in heart rate are anticipated following MDMA administration. Therefore, the secondary purpose of this study is to evaluate the effect of food on the safety and tolerability of oral MDMA, as well as MDMA effects on electrocardiogram (ECG). Directly comparing the pharmacokinetics of MDMA and its active metabolite MDA, in a within-subject crossover study will allow for assessment of any impacts of food and inform product labeling.
This study will evaluate safety, tolerability and pharmacokinetics (PK) of AZD7503, following subcutaneous (SC) administration of single ascending doses of AZD7503 in healthy participants.
