Active clinical trials for "Telangiectasis"

This research study is studying to see whether bevacizumab may treat chronic bleeding and iron deficiency anemia in Hereditary Hemorrhagic Telangiectasia (HHT). Hereditary Hemorrhagic Telangiectasia (HHT) is a disorder that causes abnormal blood vessel formation. In HHT, there is a mutation in the TGF-β pathway, which results in an increase of vascular endothelial growth factor (VEGF) levels. An increase in VEGF levels can result in poorly formed blood vessels that have a higher rate of bleeding than normal blood vessels. Bevacizumab is designed to block VEGF activity. It is believed that targeting increased VEGF levels may be able to treat HHT. This research study involves the following study drug: - Bevacizumab

Ataxia telangiectasia is a rare, genetic and progressive condition with no known cure. Therapies present a mainstream management option and have the potential to offer optimisation of fitness and general health. This pilot RCT aims to explore the effectiveness, feasibility, and acceptability of a co-produced home-based complex exercise intervention for children with ataxia telangiectasia. The study was designed through broad consultation with a collaborative of children and young people with A-T including family members, therapists, clinicians and researchers, called the A-Team collaborative (https://osf.io/edzn3/)

During the Efficacy Study (Part B), the investigators will study whether Pazopanib, taken daily for 24 weeks, will reduce the severity of nose bleeds in patients with hereditary hemorrhagic telangiectasia (HHT). Patients will either be provided active drug or a placebo [sugar - inactive pill], and be tested for nose bleed severity throughout the trial, including particularly nose bleed duration. Investigators will also test for blood loss, as well as for safety. This study is funded by the US Department of Defense USAMRAA and FDA/OOPD.

Patients affected by hereditary hemorrhagic telangiectasia (HHT) very often suffer from recurrent nosebleeds called epistaxis. There is no treatment currently available to reduce the frequency or severity of epistaxis. This research project will examine the effect of nintedanib, a capsule to be taken twice a day, on the frequency and severity of epistaxis in HHT. The study will take place at the Respiratory medicine department of the Lausanne University Hospital (Centre hospitalier universitaire vaudois, CHUV). The investigators will recruit about 48 participants with HHT, who will be divided in 2 groups. Each group will perform the same examinations and follow-up visits. The study will begin with 2 months of observation during which subjects will be asked to fill a diary to record the number and duration of epistaxis episodes. The diary will be filled daily for the entire duration of the study, i.e. 8 months. After 2 months of observation, the treatment phase will begin. Participants will take a capsule (nintedanib 150 mg or placebo) once a day for 2 weeks, then twice a day for 14 weeks. In case of intolerance at the dose of 2 capsules per day, the treatment may be reduced to 1 capsule per day. Subjects will also have to mention on the diary any blood transfusion, iron perfusion, and any symptoms they may be experiencing. Following the 16 weeks of treatment, an 8-week follow-up period will allow to observe the effects of nintedanib after the end of the treatment period, and to monitor any unexpected adverse events.

This is a multinational, multicenter, open-label, rater-blinded prospective Phase II study which will assess the safety and efficacy of N-Acetyl-L-Leucine (IB1001) for the treatment of Ataxia-Telangiectasia (A-T). There are two phases to this study: the Parent Study, and the Extension Phase. The Parent Study evaluates the safety and efficacy of N-Acetyl-L-Leucine (IB1001) for the symptomatic treatment of A-T. The Extension Phase evaluates the long-term safety and efficacy of IB1001 for the neuroprotective, disease-modifying treatment of A-T.

All early breast cancer patients are offered adjuvant breast radiation therapy (RT) after breast conserving surgery for an early breast cancer. Breast cancer is heterogeneous, and selected patients have a very low gain from RT, whilst they still have risk of acute and late side effects from RT. This trial will try identify selection criteria for low risk breast cancer patients who can safely omit adjuvant RT without unacceptable high risk of local failure.

Idiopathic juxtafoveal telangiectasia type 1 is a rare unilateral disease that mostly affects men before 50 years of age. Mac Tel 1 are characterized by microvascular telangiectasia and increased tortuosity of the macular capillary network on the temporal part of the fovea that can be identified on fundus examination. It can be associated with peripheral vascular changes, similar to manifestations of Coats' disease. It can be complicated by macular edema due to leakage from microvascular ectasia. When associated with visual loss, macular edema can be treated with different strategies although there is no consensus about the best approach. Laser can be performed on leaky aneurysms with questionable long term efficacy and potential irreversible adverse effects. Recently, anti-VEGF agents have been put forward as particularly good candidates to treat this macular edema, as observed in vein occlusion or diabetic macular edema. Indeed, in limited case series, the first anti-VEGF agents (ranibizumab and bevacizumab) showed mitigated results. More recently, authors have reported some favorable results with aflibercept in patients refractory to other anti-VEGF agents. Indeed a recent study reported both good anatomical and functional results in macular edema due to Mac Tel 1 in a non-comparative study that included 8 patients and carried out a concomitant quantification of growth factors. As an explanation, the authors found that levels of placental growth factor (PlGF), which is targeted by aflibercept but not by other anti-VEGF agents, were decreased after treatment. Moreover, PlGF correlated with capillary plexus densities assessed by OCTA. The aim of this study is thus to assess the efficacy of a 6 months treatment by aflibercept compared to placebo in macular edema linked to Mac Tel 1 with a multicenter double-blind randomized clinical trial.

Coats disease is a predominantly unilateral progressive retinal vascular disease, characterized by retinal telangiectasias with intra- or subretinal exudate deposits, which can lead to retinal detachment and one-sided blindness. Several treatment modalities are available and the choice of one of them depends on the stage of the disease and the habits of each center (laser photocoagulation, cryotherapy ...). VEGF (Vascular Endothelial Growth Factor) was found to be significantly elevated in the aqueous humor and subretinal fluid of patients with Coats disease. Several studies have shown the potential efficacy of intra-vitreous injections of anti-VEGF. But the results on their effectiveness have been evaluated only on small series of patients. Most published studies have analyzed their efficacy combined with another treatment, mainly laser photocoagulation. The true efficacy of anti-VEGF therapy as initial therapy, and then combined in Coats disease remains unknown. Currently, several centers are initiating first-line anti-VEGF injections, although no rigorous evaluation of this therapeutic strategy has been conducted. The identification of the best treatment regimen will allow in the future the reduction of laser reprocessing and will ensure a better functional benefit in the affected patients.

The purpose of this Phase 1b proof of concept study, randomised, placebo controlled, double blind, multicentre study is to asssess safety and efficacy of 2 doses of VAD044 in adult HHT patients

This pilot study is to determine the safety and efficacy of oral sirolimus (blood trough level 6-10ng/ml) in patients with HHT that are experiencing moderate or severe epistaxis. The effect of oral sirolimus on epistaxis will be compared to baseline using the Patient-Reported Outcome of cumulative weekly nose Bleeding Duration (PRO-CB). The PRO-CB association with biomarker variability over the duration of the study will be investigated. In the pilot study subjects will be treated with 2mg of sirolimus once daily to obtain a trough level of 6-10ng/ml for 3 months.
