Multicenter, Post-Market Study to Assess Outcomes of Patients Treated With the AFX System Compared to Other EVAR Devices for Endovascular Abdominal Aortic Aneurysm Repair: LEOPARD
This study is a prospective, randomized, multi-center study, intended to evaluate the
outcomes of contemporary EVAR (Endovascular Aneurysm Repair) in a real world population. The
study is designed to compare the anatomically stabilized AFX Endograft System to a reference
group of proximally fixated EVAR devices. Patients will be randomized between the two
groups.
Randomization will be 1:1. Each investigator will select one comparator device of their
choice before enrolling the first patient. The study will sequentially evaluate
non-inferiority and superiority hypotheses.
Up to 80 sites with experience in EVAR and up to 800 subjects will participate in this
study.
A PHASE IIIb, MULTICENTRE, RANDOMIZED, DOUBLE BLIND, PLACEBO CONTROLLED STUDY EVALUATING THE EFFICACY AND SAFETY OF DYSPORT USING 2 mL DILUTION IN ADULTS WITH CERVICAL DYSTONIA A-TL-52120-169
A multicentre, randomised, double blind, placebo controlled study where at study entry, subjects will be randomised in a ratio of 2:1 to receive either Dysport or placebo. The primary objective of the study is to evaluate the efficacy and safety of Dysport 500 units (U)/vial using 2 mL dilution compared with placebo for the treatment of cervical dystonia (CD). All subjects are planned to have a single treatment in this study. Following study treatment, follow up visits will be performed at Week 2, Week 4 and Week 12 (+28 days/4 weeks) or early withdrawal due to any reason. All subjects who complete the Week 12 visit will be considered to have completed the study and will be offered entry into an open label extension (OLE) study, which consists of up to three treatment cycles of Dysport using the 2 mL dilution scheme. Between Weeks 4 and 8, subjects may be deemed eligible for early entry into the OLE study, i.e. before they reach the planned Week 12 study visit if rescue treatment is needed. Approximately 132 male and female subjects with CD will be enrolled. The primary efficacy endpoint is the change from baseline in TWSTRS total score at Week 4. Clinical Trial Rationale:The current USPI allows for only one dilution of Dysport: 500 U in 1 mL volume. Feedback obtained from scientific experts and Investigators at medical advisory boards and in market research data has pointed to the lack of scientific data supporting a 2 mL dilution as an obstacle to providing appropriate, safe and effective Dysport utilisation in the USA for subjects suffering from CD. Despite the lack of labelled information, the 2 mL dilution with Dysport reflects real world clinical practice in the USA.The addition of data in the USPI supporting the safety and efficacy of a 2 mL dilution with Dysport will provide the clinician more flexibility in injection volume range to better equip them to meet the needs of a broader spectrum of subjects with CD. Therefore, in this clinical study the majority of enrolled subjects will be previously treated with Botox to reflect the real world clinical scenario in the USA.Statistical analyses will be performed by an external CRO. Statistical evaluation will be performed by using SAS. Exploratory analysis will be performed for each of the tertiary secondary efficacy endpoints using appropriate methods.
