This is a multi-center, prospective, single-arm, non-randomized, staged, pivotal clinical study to evaluate the safety and performance of the aXess graft in subjects aged 18 and above, diagnosed with end-stage kidney disease, and possessing an estimated glomerular filtration rate (eGFR) less than 20 ml/min, who intend to undergo hemodialysis but are considered unsuitable candidates for fistula creation by the investigating surgeon. The alternative option is called an arterio-venous graft (AVG), where the doctor implants a synthetic/artificial tube under the patient's skin, where one end of the tube connects to a vein and the other to an artery. This tube is then used as the ‘access site' during hemodialysis. Participants with ESRD in need of vascular access, and who agree to be in this study, and also meet all the eligibility criteria for participation, will receive the Xeltis aXess graft, a type of AVG as previously described.
The GRIT-PKP2 study will evaluate the long-term safety and tolerability of LX2020 gene therapy for subjects with PKP2-ACM who have previously received an investigational study medication called LX2020. PKP2-ACM is an inherited heart condition which can cause heart muscle and electrical damage. Investigational means it is not approved for use by the Food and Drug Administration (FDA). There is no investigational treatment being administered in this study. The overall study duration is 4 years. The study consists of 7 visits: a rollover visit, an outpatient monitoring period, (5 visits, 18 months to 48 months after LX2020 administration in Study LX2020-01), and an end-of-study visit. Procedures and activities that subjects will undergo are: quality of life questionnaires, ECG, MRI, ultrasound, ECHO, collection of samples, remote cardiac monitoring, and collection of vital signs.
This cross-sectional study aims to examine the impact of visual cues on listeners' perception of speaker age. Eligible speaking participants include adult males and females between the ages of 18–90 years old without voice or hearing disorders. Eligibility will be determined by research coordinators via patient demographic forms and validated voice and hearing assessments. Speaking participants will have two audio recordings taken: (1) sustained vowel sound and (2) reading of the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V), a standardized tool employed to evaluate the perceptual characteristics of voice quality across a wide age range. To develop the materials for the listening participants, CAPE-V audio recordings obtained from the speaking participants will be systematically paired with race and age-matched photographs obtained from a publicly available database. The finalized materials will encompass three experimental conditions: (1) audio only, (2) audio presented with a standardized photograph of an individual matched to the speaker's gender and age, and (3) audio presented with a standardized photograph of an individual matched for gender but differing in age. Naïve listening participants, blinded to the experimental conditions, will then be presented with these materials in a randomized order and asked to estimate the perceived ages of the speakers. Additionally, basic acoustic analyses of each sustained vowel sound recording (e.g., jitter, shimmer) will be conducted by a trained professional using the speech analysis software PRAAT.
This study is enrolling two different groups of individuals. The first group are those individuals referred for right heart catheterization (RHC), which is a procedure performed to check heart pressure taken inside the heart. The second group of individuals are those who have tricuspid regurgitation (TR) (blood that leaks due to improper valve closure) and are undergoing tricuspid valve intervention to correct the regurgitation. The RHC group will be referred to as the control group and the tricuspid intervention group will be the treatment group in this study. This study involves collecting existing medical records on both groups, as well as an arterial (from an artery) blood sample and venous (from a vein) blood sample from the vein that carries blood away from the liver. The control group will not involve any additional procedures or follow up. The TR population will perform a 6 minute hall walk test before their tricuspid valve intervention and again during the six month post procedure follow up. The TR group will also have repeat arterial and venous blood collection at the six month follow up. The TR group will have data collected for up to two years post tricuspid valve intervention.
The purpose of this rollover study is to investigate the long-term safety of etavopivat in participants11 months of age and older with SCD or thalassaemia who have completed a treatment period in previous etavopivat studies (parent studies, see Section 4.1). Long-term clinical efficacy measures of etavopivat treatment will also be assessed. This study will also ensure that participants who are benefiting from etavopivat treatment have prolonged access to the drug in the time before it is commercially available in their country.
The goal of the current project is to gather preliminary data from adults across the United States using an online survey study regarding alternative cannabinoid use, motivations, and experiences. We will also conduct interviews with some participants to gather more open-ended responses regarding the targets of interest in order to inform future work about alternative cannabinoids.
This study is for adults aged 18 to 39 who have a history of cancer and have not had inherited cancer genetic testing. The purpose of this study is to find out if a digital tool can be used as an alternative to meeting with a genetic counselor before inherited cancer genetic testing, and whether this approach can help support patients through the testing process. The study will compare the digital tool to the usual approach for genetic testing, which involves meeting with a genetic counselor before and after testing.
Participants will be randomly assigned (like flipping a coin) to one of two groups. One group will receive pre-test education through a digital tool, and the other group will meet with a genetic counselor through a telehealth visit. All participants will receive their genetic test results through a telehealth visit with a genetic counselor. Participants in the digital tool group will also have access to a chatbot called the Genetics Journey Chatbot that provides educational support, reminders, and answers to questions during the study.
The study involves completing surveys at several time points: before genetic testing, after the testing decision, after receiving results, and again about 6 and 12 months later. The total duration of participation is about 18 months.
This study does not involve an investigational drug. Participants may benefit from learning whether they have a genetic change that could increase their risk of cancer, which could inform their future screening or prevention options. The information learned from this study may also help improve genetic testing delivery for future patients.
There will be a total of 10 patients enrolled locally over the course of 24 months.
This study is enrolling participants with risk factors for heart or blood vessel events (e.g. heart attack, stroke, etc) who also have an elevated lipoprotein a (Lp(a)), which is a sticky particle in the blood that carries cholesterol. The first part of the study involves testing the Lp(a) level and if elevated then participants will be invited to be a part of a study testing the investigational medication olpasiran. Investigational means it has not been approved for commercial use by the Food and Drug Administration. The study medication is given as a shot just under the skin every 3 months. This study is a randomized study meaning participants are assigned by chance to either receive olpasiran or placebo. Placebo looks like the real medication but has no active ingredients. Participants have a 50:50 chance of being assigned to either group but will not know which group they are in. Study related procedures include physical exams, blood work, vital signs, electrocardiogram (ECG - a tracing of the heart's electrical activity) and study medication administration. This study is expected to last about three and a half to five and a half years and involve between 16 to 28 visits.
This study is an open label extension of the ACT-EARLY study. which included those with no evidence of ATTR but are known carriers of disease causing TTR gene. ATTR stands for transthyretin amyloidosis. It is a condition in which a protein called transthyretin (TTR) accumulates in various organs, including the heart (known as ATTR-CM), kidneys, and nerves (known as ATTR-PN). This accumulation can lead to damage and dysfunction in these organs.
This study will continue using the study drug acoramidis (AG-10) to determine if it can help people with the genetic TTR variant slow the progression of ATTR. AG-10 is an investigational drug. Investigational means that AG-10 is not yet approved for use in any settings outside of clinical research studies like this one. Reducing the amount of TTR in your blood may reduce the amount of amyloid deposits in your body and may keep your cardiomyopathy from getting worse over time.
Participation in this study will last up to 60 month and will consist of about 13 clinic visits and about 11 telephone follow up visits. Some tests required include physical exams, medical and surgical history, bloodwork, questionnaire, electrocardiogram (test that records your heart's electrical activity), echocardiogram (ultrasound test of your heart) and study drug administration.
This study will see if the experimental medicine MTX-463 can slow or stop idiopathic pulmonary fibrosis (IPF) from worsening in people at least 40 years of age or older. Participants will receive either MTX-463 or a placebo (which contains no active drug) through an intravenous infusion once every 4 weeks, for a total of 6 infusions. Overall, participants will attend a total of 9 visits over the course of approximately 32 weeks, or roughly 8 months.
