January 25, 2017 updated by: Oswaldo A Henriquez, Emory University

The purpose of this study is to compare a new treatment for nosebleeds to the treatment that has been used for many years.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Nosebleeds are a common condition which affect many Americans every day.The standard treatment in this hospital for nosebleeds that do not resolve with squeezing the nose or nasal spray is to place a nasal packing (aka nasal tampon) into the nose. This is an effective treatment in most cases, but patients may find it to be uncomfortable. The investigators will be comparing the standard nasal packing with a new type of powder which may also stop nosebleeds.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: Microporous Polysaccharide Hemospheres (MPH)
Subjects with acute epistaxis will receive microporous polysaccharide hemospheres (Arista) powder. In the event that Arista fails to assist in resolving nosebleed in 15 minutes, subjects will be promptly escalated to the control group and will receive Merocel.
Device: Microporous Polysaccharide Hemospheres
Two grams of Arista powder will be placed into the nose followed by four minutes of pressure and a moustache dressing.
Other Names:
  • Arista
Device: Nasal Tampon
8 cm of Merocel dressing will be placed into one or both sides of your nose for the next three to five days and will then be removed by the physician.
Other Names:
  • Merocel
Active Comparator: Merocel (Control)
Subjects with acute epistaxis will receive standard-of-care treatment, nasal tampon (Merocel). In the event that Merocel fails to assist in resolving nosebleed in 15 minutes, subjects will be promptly escalated to the MPH group and will receive Arista powder.
Device: Microporous Polysaccharide Hemospheres
Two grams of Arista powder will be placed into the nose followed by four minutes of pressure and a moustache dressing.
Other Names:
  • Arista
Device: Nasal Tampon
8 cm of Merocel dressing will be placed into one or both sides of your nose for the next three to five days and will then be removed by the physician.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of subjects with resolution of bleed
Time Frame: 15 minutes (average time to resolve bleeding)
Resolution of bleeding is determined by cessation of blood flow anteriorly from the nares as well as posteriorly in the pharynx. This will be determined by the otolaryngology resident or attending managing the patient during the study.
15 minutes (average time to resolve bleeding)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Time until resolution of bleeding
Time Frame: 15 minutes (average time to resolve bleeding)
Number of minutes it takes to resolve bleeding comparing the Arista powder group versus the Merocel tampon group.
15 minutes (average time to resolve bleeding)

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.

For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
