Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Withdrawn

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

World knowledge about this virus is accumulating but data about the clinical presentations of infected patients and common treatments, including ribavirin, interferon and methylprednisolone, lack evidence. Although drugs with anti- coronavirus (CoV) activities have been identified, as yet no anti- MERs- CoV drug has been approved and a vaccine has yet to be developed. Previous reports on other viral infections including SARS have suggested that convalescent plasma or serum is effective where no other treatment is available or in an emergency. A recently completed systematic review and meta-analysis by the University of Nottingham - World Health Organization Collaborating Center indicates that convalescent plasma therapy may be the most promising near-term therapy patients with for MERS- CoV infection. In this study, investigators will study the pharmacokinetics of immunoglobulin in response to convalescent plasma administration in order to inform a much larger study which will investigate the efficacy of convalescent plasma. Plasma will be collected from patients who recently recovered from MERS-CoV, Health Care Workers who had potential exposure and are tested for anti MERS-CoV serology and RT-PCR after obtaining their consent. This convalescent plasma will be stored in the blood bank as per their policies and procedures. Patients with MERS-CoV positive after meeting the eligibility criteria will receive 2 units of convalescent plasma . Clinical data as well as the standard laboratory studies will be collected at baseline, 30 mins after first dose, 30 mins after second dose, day 1, 3, 7, 14, 28 of hospital stay after enrollment.

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 (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Age greater than or equal to 14 years of age
  • Inpatients who are MERS-COV positive (by PCR)
  • Willingness to have blood, respiratory and urine samples obtained and stored for subsequent analysis.

Exclusion Criteria:

  • Clinical evidence (in the judgment of the site investigator) that the etiology of illness is primarily not MERS-CoV in origin.
  • History of allergic reaction to blood or plasma products (as judged by the investigator)
  • Known IgA deficiency
