Enhancing Anti--Tetanus Vaccine Response After Autologous Stem Cell Transplantation

March 8, 2024 updated by: University of Nebraska

A Phase II Study of Enhancing Anti-Tetanus Vaccine Response After Autologous Stem Cell Transplantation

This pilot randomized Phase II trial (10 subjects per arm) will compare immune reconstitution following transplantation of an autologous mobilized graft product to reconstitution following transplantation of a mobilized graft product followed by an autologous lymphocyte infusion collected prior to G-CSF mobilization. All subjects will receive tetanus vaccines pre and post-transplant. The primary end point will be tetanus vaccine immune responses post-transplant.

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

PRIMARY OBJECTIVES:

  1. To compare the cellular and humoral vaccine response post-transplant between the two arms by performing Elisa, and T-cell enzyme-linked immunospot (ELISPOT) assays
  2. To determine the feasibility and safety of this approach

SECONDARY OBJECTIVES:

  1. To compare post-transplant recovery of innate and adaptive immune cells (CD8, CD4, CD19, NK, γδ T-cells), in addition to T-cell phenotype markers between the two arms.
  2. To compare post-transplant recovery of T-regs and MDSCs between the two arms.
  3. To compare progression free survival (PFS) at 2 years post-transplant

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.

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

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

  14. A female of child-bearing potential, must have two negative urine pregnancy test results within 10 to 14 days prior to starting the first dose of vaccine pre-transplant as a way of ensuring safe transplant planning.

Exclusion Criteria:

  1. Participation in another clinical study with an investigational product during the last 28 days.
  2. Prior stem cell transplant (either autologous or allogeneic)
  3. Creatinine clearance < 60 ml/min (calculated)
  4. High risk MM defined as those with the following disease, fluorescence in situ hybridization and/or cytogenetic features: del17p, del1p with 1q gain, t(4;14), t(14;16), t(14;20), >1 cytogenetic abnormality on karyotype, hypodiploid, plasma cell leukemia (primary or secondary), or subjects who failed to achieve ≥PR to induction therapy (i.e. VRd) and required salvage induction prior to AHSCT.
  5. Documented central nervous system or extramedullary disease.
  6. Significant organ dysfunction deemed to carry inappropriate risk for AHSCT.
  7. Intention or plans for cyclophosphamide mobilization.
  8. Known allergic reactions after previous tetanus diphtheria vaccination or had a condition of Guillain Barre Syndrome (GBS)
  9. Known active hepatitis B, C or HIV infections on initial assessment.
