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.

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Study Group: Prospective Evaluation of Flexagon SFM Device with OTOLoc
This is a multicenter, single-arm study in which clinical outcomes are prospectively evaluated for subjects undergoing gastric-jejunal anastomosis using the Flexagon SFM Device with OTOLoc.
Device: Gastric-Jejunal Anastomosis with Flexagon SFM Device with OTOLoc
This study will investigate one type of intervention: gastric-jejunal anastomosis creation in subjects undergoing surgical procedures. Flexagon SFMs and OTOLoc devices will be delivered laparoscopically and/or endoscopically into portions of the stomach and the jejunum that are intended to be anastomosed. An OTOLoc device will be deployed into the gastric wall of the stomach to provide access for the deployment of a Flexagon SFM into the stomach. The process is repeated at an intended section of jejunum. Once deployed, the Flexagon SFMs are approximated and positioned, after which the SFMs are couple together to form the anastomosis, with the OTOLoc devices allowing fluidic communication between the two lumens until the anastomosis is fully formed.
