Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Instylla Hydrogel Embolic System (HES) including Instylla Delivery Kit and Instylla Microcatheter.
This involvement for the patient is the same procedures, activities and processes used for standard vascular embolization procedures.
Subjects will be treated within this protocol by an interventionalist with substantial prior experience with vascular embolization procedure.
The mode of delivery will be performed face to face and the location will be at the hospital.
The number of interventions that will be delivered will be one time and possible more over the 30 day follow-up period. The procedure will take about the same time as a standard embolic procedure (about 30 minutes to an hour).
The interventionalist will decide if more procedures are administered.

Outcomes
Primary outcome [1] 323158 0
Incidence of serious device and serious procedure-related adverse events and non target embolization. Events will be reviewed by an Independent Medical Monitor. (composite endpoint) There are no known unique risks associated with the Instylla HES. Throughout the duration of the study, subjects will be clinically evaluated (imaging and blood lab tests) and assessed for adverse events using the grading of the NCI Common Terminology Criteria for Adverse Events (CTCAE Version 5.0). Severity of complications will be further classified in accordance with Society of Interventional Radiology (SIR) guidelines.
Timepoint [1] 323158 0
30 days post-embolization
Secondary outcome [1] 380972 0
Technical success of achieving embolization demonstrated by post procedure angiography.
Timepoint [1] 380972 0
Immediately after embolisation procedure

Eligibility

3. Positive angiographic findings of bleeding
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. Ongoing adverse effect that may confound the evaluation of the Instylla HES
2. Pregnant females
3. The patient has other concurrent conditions or known history that in the opinion of the Investigator would be unlikely to receive clinical benefit from the study procedure or participation in the study may compromise patient safety or study objectives (including but not limited to ongoing infection, morbid obesity).

Other reasons
The study was prematurely terminated because of the situation that arose after the COVID-19 pandemic hit. Site locations were closed, and clinical studies put on hold worldwide. Once sites were opened and studies allowed, Instylla Inc. decided to investigate Instylla HES in a large-scale clinical investigation in other geographical locations.

Summary
Brief summary
This study will evaluate the safety and performance of the Instylla Hydrogel Embolic System for patients requiring vascular embolisation for treatment of bleeds.

Who is it for?
You may be eligible to join this study if you are aged 18 and above and are requiring vascular embolisation for treatment of bleeds.

Study details
All participants will receive vascular embolisation using the Instylla Hydrogel Embolic System (HES) including Instylla Delivery Kit and Instylla Microcatheter. Safety and performance of the HES will be assessed using using the grading of the NCI Common Terminology Criteria for Adverse Events (CTCAE Version 5.0). Severity of complications will be further classified in accordance with Society of Interventional Radiology (SIR) guidelines. for up to 30 days post-embolisation.

This study will also allow a greater understanding of whether HES can be used to embolise vascular bleeds.
