Filter by:Clinical evaluation of vaccines against respiratory viruses is currently based on the analysis of systemic immune responses, whereas respiratory immunity is the first line of defense against respiratory pathogens. In addition to secretory immunoglobulin A (IgA) in mucosal fluids which are essential to neutralize the pathogens at mucosal surfaces, tissue-resident memory immune cells have been shown to be crucial in protection. Furthermore, memory immune cells in blood able to migrate to airway tissues also play a crucial role. Airway immune responses have not been studied a lot due to the lack of a standardized methodology to evaluate them in humans.
This study is a single-arm, single-center trial aimed at evaluating the safety, pharmacokinetics, biodistribution and dosimetry of 68Ga-LNC1007 Injection in adult healthy volunteers and solid tumor patients. All participants must provide a signed informed consent form before enrolling in the trial. A total of 8 adult healthy volunteers and solid tumor patients will be involved in the trial. There should be no less than 3 and no more than 5 participants in either group. If any participant drops out during the trial, or an effective scan image becomes unavailable, additional volunteers will be recruited to ensure the sample size. The participant will receive a single intravenous injection with 68Ga-LNC1007 Injection.Each subject will participate in the study for approximately 3 weeks, including 2 weeks of screening, 1 week of scanning and safety follow-up.
The purpose of this general screening protocol is to facilitate recruitment into studies conducted at the Center for Virology and Vaccine Research (CVVR) or Division of Infectious Diseases at Beth Israel Deaconess Medical Center. This general screening protocol will help to determine the eligibility of potential volunteers for any vaccine or therapeutic trials open for recruitment or soon to be opened.
This is a randomized (1:1), double-blind, double-dummy, phase I study to compare the effects of Omadacycline versus Moxifloxacin on gut microbiota and the resistomes in healthy adult volunteers.The study consists of 3 phases: Screening, double-blind treatment, and follow-up. Healthy volunteers aged 18-40 years, who meet entry criteria, are randomly assigned to a treatment group using an Interactive Voice Response System/Interactive Web Response System (IxRS) and receive the first dose of the study drug.
The main objective is to study how astegolimab may behave in the body when injected subcutaneously into the abdomen, thigh, or upper arm in healthy participants.
In this study, researchers will learn more about a study drug called BIIB080. BIIB080 is currently a drug under investigation for treatment of Alzheimer's disease. The main question researchers are trying to answer in this study is how radiolabeled BIIB080 distributes in the brain and spinal cord. To help answer this question, researchers will use positron emission tomography (PET) scanner that can detect radiolabeled BIIB080 after a single injection of a small dose of radiolabeled BIIB080 ([89Zr]Zr-DFO-BIIB080) and a dose of BIIB080 together via an intrathecal (IT) injection in healthy volunteers. Researchers will also learn about the safety of injecting radiolabeled BIIB080 and BIIB080 together.
This study is researching an experimental drug called ALN-ANG3 (called "study drug"). The study is focused on healthy participants. The aim of the study is to see how safe and tolerable the study drug is in healthy adults. The study is looking at several other research questions, including: - What side effects may happen from taking the study drug - How much study drug is in the blood at different times - Whether the body makes antibodies against the study drug (which could make the drug less effective or could lead to side effects)
This is a single-dose study to assess the effect of mild or moderate Hepatic Impairment (HI) on the Pharmacokinetics (PK) of rilzabrutinib as well as to evaluate the safety and tolerability of rilzabrutinib in subjects with HI.
This is a single-dose and multiple doses study to assess the Pharmacokinetics (PK) of rilzabrutinib as well as to evaluate the tolerability of rilzabrutinib in Japanese and Caucasian Healthy Male and Female subjects.
This study is researching experimental drugs called REGN9933 and REGN7508 (called "study drugs") and comparing their effects to approved treatments of rivaroxaban and aspirin (called "standard treatments"). Aspirin will be given alone or in combination with the study drugs or the other standard treatments to look at their effects on blood loss in the intestines. The aim of the study is to see if aspirin alone or the study drugs REGN9933 and REGN7508, when taken with aspirin, cause less minor intestinal bleeding than standard treatments rivaroxaban with aspirin. The study is looking at several other research questions, including: - What side effects may happen from taking the study drug - How much study drug is in the blood at different times - Whether the body makes antibodies against the study drug (which could make the drug less effective or could lead to side effects)
