CraniSeal Post Approval Study

February 19, 2026 updated by: Pramand LLC

A Multicenter, Single-Blind, Prospective Randomized Post-Approval Study Comparing the Safety and Effectiveness of CraniSeal Dural Sealant to DuraSeal Dural Sealant for Dural Sealing in Elective Cranial Surgery

To collect post-approval data comparing the safety and effectiveness of CraniSeal Dural Sealant to DuraSeal Dural Sealant. The study has been powered specifically to determine whether the CraniSeal device when used as an adjunct to sutured dural closure following elective cranial surgery is no worse than (i.e., non-inferior) to the DuraSeal device with respect to proportion of subjects free from post-operative cerebrospinal fluid (CSF) leaks. Additional safety outcomes (i.e., surgical site infections and adverse events/device-related adverse events) will also be captured and compared.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No
