Filter by:This is a randomized, double-blind, and placebo-controlled phase I clinical trial. It is designed to assess the safety, tolerability, and pharmacokinetic (PK) profile of SHEN26 capsules after single and multiple ascending dosing in healthy Chinese adult participants, and the food effect on the PK profile of SHEN26 capsules.
This study evaluates the effect of different complementary foods on the gastrointestinal microbiota of exclusively human milk fed infants.
The greatest challenge in our ageing society are cardiovascular diseases such as stroke, heart attack, peripheral artery disease of the legs with non-healing wounds (ulcers), or diabetes. Specific diets with high polyphenol content are associated with lower incidence of cardiovascular disease and can improve macrovascular function when consumed acutely and chronically. Which role the smallest blood vessels (microcirculation) play in this and if the microcirculation responds to therapies is not well understood. One reason for this is that no generally available medical instrument has the resolution to study the microcirculation. The recently developed optical coherence tomography angiography (OCTA), currently mainly used by eye doctors, is able to visualise the microcirculation. The current randomised controlled cross-over proof-of-concept study will test the acute effect of a cocoa flavanol intervention on cutaneous microvascular structure and function of hands and feet together with macrovascular function of upper and lower extremities in healthy and type 2 diabetes participants. It is the hypothesis that cocoa flavanol intervention as compared to placebo can acutely increase microvascular vasodilation and macrovascular endothelial function in arms and legs together with arterial stiffness in both healthy and type 2 diabetes participants.
The purpose of this study is to evaluate the effects of BMS-986371 on the drug levels of methotrexate, sulfasalazine and their main metabolites in healthy male adult participants.
The main purpose of this study is to measure the level of active ingredient of the study medicine (nirmatrelvir) that is secreted in human breast milk when it is given to healthy breastfeeding women. The study medicine consists of two medicines, nirmatrelvir and ritonavir. We are seeking female participants who are: - Actively breast-feeding (lactating) at least 12 weeks postpartum; - Age between 18 to 55 years and not currently pregnant; - Have a Body Mass Index (BMI): 17.5 kg/m2; and a total body weight >50 kg (110 lb). Participants will take the study medicine by mouth for a total of 3 times over 2 days (2 morning doses and 1 evening dose) at the study clinic. We will periodically collect breast milk from day 2 to 4 to measure the level of nirmatrelvir and ritonavir in it. A safety follow up call will be conducted around 28-35 days from the last dose to monitor any reactions participants may have to the study medicine.
The purpose of this study is to explore the physiological and behavioral impact of the immune response to vaccines after receipt of investigational or approved messenger ribonucleic acid (mRNA) vaccines using wearable medical sensors, with the potential of establishing a digital biomarker of vaccine response due to stimulation of the immune system.
Curcumin, Omega-3 and Vitamin-D (COD) are commonly used dietary supplements, which are licensed natural health products in Canada. The investigators are interested to see what effects (good or bad) these supplements taken in combination, might have on a person and the potential impact of these supplements, in combination, on inflammation and the immune system, in the body. This is because the investigators study Rheumatoid Arthritis (RA), an autoimmune disease that affects the joints of the body, causing joint pain and swelling. The investigators want to first evaluate the tolerability and potential negative effects of these three supplements in combination, also known as "side-effects" in healthy persons. This pilot study will also help us determine the length of time research participants need for their research visits for future clinical trials. The investigators also want to explore the utility and validity of two different 24-hour food recall methods (ASA24-Canada-2018 and Keenoa food diary) and the dietary inflammatory index (DII) using both recall methods. The DII is a score calculated from dietary data, to establish the inflammatory potential of an individual's diet. This research pilot study aims to enroll 50 persons. The investigators want to identify common side effects of the supplements when all three are taken together, as well as any other potential side-effects that might occur that are not common. Based on the scientific research, persons who have taken these supplements individually (e.g., Vitamin D alone or Omega-3 alone), show that serious side effects are unlikely and if they do occur are mild. Pure curcumin, like that being administered in this study, containing no fillers, has not shown to have adverse effects and is well tolerated. However, no scientific studies have been done using all three of these nutritional supplements together, in humans.
This study will assess absorption, metabolism, and excretion of Radioactively Labeled Etrumadenant in healthy volunteers.
The purpose of this study is to assess the drug levels of BMS-986166 in healthy male participants.
This study will assess the effect of multiple doses of AZD5462 on the PK of oral midazolam (CYP3A4 probe), rosuvastatin (OATP1B1/3, BCRP probe), and digoxin (P-gp probe) in healthy participants. This study will consist of 2 treatment arms (Treatment Arms A and B) and within each treatment arm, the participants will first be administered the probe substrates (midazolam, rosuvastatin, and digoxin) alone followed by administration of the probe substrates together with AZD5462. The treatment arms differ in the dose of AZD5462 being administered and will be performed sequentially starting with Treatment Arm A (AZD5462 Dose A, high dose treatment arm) and followed by Treatment Arm B (AZD5462 Dose B, low dose treatment arm). Each treatment arm will include 5 periods. Thirty two participants in total (16 participants per treatment arm) will be enrolled to ensure at least 24 evaluable participants (12 participants per treatment arm) at the end of the last treatment period. A follow-up visit at Day 24 (+-1 Day) will be conducted via a phone call.
