Flu Vaccine Study in Neuromuscular Patients 2011

October 14, 2020 updated by: Children's Hospital Medical Center, Cincinnati

Comparison of the Immunogenicity of Intramuscular Versus Subcutaneous Administration of Trivalent Inactivated Influenza Vaccine in Individuals With Neuromuscular Diseases

The purpose of the study is to compare the immune response of two different injection methods (Intramuscular V.S. Subcutaneous) of the 2011-2012 seasonal Influenza (Flu) vaccine among patients with neuromuscular conditions who have significant muscle degeneration. This research study hypothesizes that the subcutaneous route of vaccine administration, as compared to the intramuscular route, may confer at least comparable, or possibly better, immunogenicity. At least 30 individuals followed by the CCHMC Neuromuscular Comprehensive Care Center will be recruited to participate in this study lasting approximately one to two months with two clinic visits and one follow-up telephone call. Immunogenicity will be assessed by comparing hemagglutination inhibition (HI) antibody titers obtained pre- and post-vaccination.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Individuals with neuromuscular diseases are more prone to influenza-related morbidity. Vaccination is the most effective measure to reduce the influenza disease burden. In the United States, the recommended route of administration for the inactivated influenza vaccine is intramuscular. In other countries, the subcutaneous, deep subcutaneous, and intramuscular routes are all considered acceptable for influenza vaccine administration. The United States CDC states that subcutaneous influenza vaccine doses, provided they are age-appropriate, may be counted as valid.

Those with neuromuscular diseases have muscle fibrosis that may potentially make intramuscular vaccines more effective. Those with Duchenne muscular dystrophy receive systemic corticosteroids to reduce inflammation. Corticosteroids may suppress antibody responses to vaccines. The goal of this research study is to evaluate the immunogenicity and safety of intramuscular and subcutaneous administration of inactivated influenza vaccine in individuals with neuromuscular diseases. This is a single site, open-label, randomized study. At the first visit, a blood sample was collected prior to vaccination. Each subject received either an intramuscular or subcutaneous vaccine administered in the anterolateral aspect of the thigh. Within 30 minutes of vaccination, subjects rated pain at the injection site using a numeric pain scale (0-10). Subjects and their caregivers were also asked to record local and systemic adverse events on diary sheets from day 0 to day 4 after vaccination. Subjects were instructed to notify the study staff by telephone should they develop any serious adverse reactions following vaccination. At a second study visit approximately 28 days later, a repeat blood sample was obtained. The blood samples obtained pre-vaccination and also at day 28 were tested for hemagglutination inhibition (HI) titers to the three influenza vaccine strains. rovider's office. The geometric mean titer ratios for each of the three vaccine strains were calculated as the ratios of postvaccination to prevaccination titers at geometric mean scale.

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

3 years to 35 years (ADULT, CHILD)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Non-ambulatory;
  • Quadriceps muscle strength of MRC (Medical Research Council Scale) grade 3 or below
  • Any subject who is between 3 to 8 years of age must have received at least two doses of influenza vaccine last season or at least one dose tow or more years ago.

Exclusion Criteria:

  • Subject must not have a history of severe reactions following previous immunization with influenza vaccine.
  • Subject must not have previously received a 2011-2012 influenza vaccine.
  • Subject must not have a history of Guillain-Barre syndrome.
  • Subject must not have received a live viral vaccine (i.e., MMR, varicella) within 28 days prior to receipt of the study vaccine.
  • Subject must not have any condition that the investigator believes would render vaccination unsafe or interfere with successful completion of the study.
