Recruitment Status : Recruiting
First Posted : August 21, 2020

Information provided by (Responsible Party):
Instylla, Inc.

Brief Summary:
To determine whether Instylla HES has the ability to effectively embolize targeted arterial segments of hypervascular tumors as well as standard of care (SOC) transarterial embolization/conventional transarterial chemoembolization, while resulting in an acceptable risk of device and procedure-related serious adverse events.

Condition or disease Intervention/treatment Phase
Hypervascular Tumors Device: Instylla HES Other: TAE or cTACE Not Applicable

Layout table for study information
Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 150 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Randomized Multi-Center, Subject and Evaluator Blinded, Parallel-Group Study to Evaluate the Safety and Effectiveness of the Instylla Hydrogel Embolic System (HES) Compared With Standard of Care Transcatheter Arterial Embolization (TAE) / Transcatheter Arterial Chemoembolization (cTACE) for Vascular Occlusion of Hypervascular Tumors; A Pivotal Study
Actual Study Start Date : January 4, 2021
Estimated Primary Completion Date : April 30, 2022
Estimated Study Completion Date : July 31, 2022

Arm Intervention/treatment
Experimental: Instylla HES Device: Instylla HES
Instylla HES is a novel liquid embolic made of primarily water and polyethylene glycol (PEG)

Active Comparator: Control
Other: TAE or cTACE
Bland TAE or cTACE
Other Name: Control

Primary Outcome Measures :
  1. Primary Effectiveness Endpoint: Delivery of the embolic agent to the index tumor feeding vessel with stasis of flow as determined by an independent radiologist via comparison of the pre and final post procedure images [ Time Frame: Immediately post-embolization procedure ]
    Stasis of flow defined as absence of contrast flow within the targeted tumor feeding vessel

  2. Primary Safety Endpoint: Freedom from major adverse events through 30 days post-index procedure [ Time Frame: 30 days post-embolization procedure ]
