Outcome Measures

Primary Outcomes (1)

  • Number of Participants Who Developed a Positive Antibody Response (IgG) to Keyhole Limpet Hemocyanin (KLH) Immunization

    Positive antibody response was defined as at least a 2-fold increase in antibody concentration on either Day 43 or Day 57 compared with baseline where baseline was assigned a value of 1 if it was below the limit of quantification. All humoral responses were assessed by enzyme-linked immunosorbent assay (ELISA).

    Baseline and Day 43 or Day 57

Secondary Outcomes (15)

  • Number of Participants Who Developed a Positive Cellular Response to KLH Immunization

    Baseline, Day 22, Day 29, Day 43, and Day 57

  • Number of Participants Who Developed Both a Positive Antibody Response and a Positive Cellular Response to KLH Immunization

    Baseline, Day 22, Day 29, Day 43 and Day 57

  • Number of Participants Who Developed a Positive Humoral Response to Tetanus Toxoid (TT)

    Baseline, Day 22, Day 29, Day 43 and Day 57

  • Number of Participants Who Developed a Positive Cellular Response to Tetanus Toxoid (TT)

    Baseline, Day 22, Day 29, Day 43 and Day 57

  • Number of Participants Who Developed a Positive Antibody Response to KLH and Positive Cellular Responses to Both KLH and TT Immunizations

    Baseline, Day 22, Day 29, Day 43 and Day 57

  • +10 more secondary outcomes

Study Arms (2)

Group A (With Daclizumab Therapy)

EXPERIMENTAL

Participants who were receiving a full course of 5 doses of daclizumab (1 milligram per kilogram \[mg/kg\]) with Day 1 vaccine administered immediately prior to the fifth dose.

Biological: DTDrug: DaclizumabBiological: KLH

Group B (Post Daclizumab Therapy)

ACTIVE COMPARATOR

Participants who completed a full course of daclizumab therapy in the previous 4 to 18 months.

Biological: DTBiological: KLH

Interventions

DTBIOLOGICAL

Diphtheria and Tetanus Toxoid (DT) will be administered intramuscularly as a 1/3 dilution (0.33 flocculation units). The participants will be rechallenged with DT 6 months after Day 29 if failed to show \>=1.5 fold increase in lymphocyte proliferative response but have a humoral response.

Group A (With Daclizumab Therapy)Group B (Post Daclizumab Therapy)

The fifth dose (1 milligram per kilogram \[mg/kg\]) of daclizumab will be administered in this study to participants who already received four doses (one dose at 1 mg/kg within 24 hours post-transplant and then every other week for 3 doses).

Also known as: Zenapax
Group A (With Daclizumab Therapy)
KLHBIOLOGICAL

KLH will be administered intradermally with a dose of 250 mcg for participants aged 2 to less than 12 years, and 500 mcg for participants aged 12 to 19 years. The participants will be rechallenged with KLH 6 months after Day 29 if failed to show specified increase in lymphocyte proliferative response or humoral response.

Eligibility Criteria

Age2 Years - 19 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Primary renal transplant recipients between 2 and 19 years of age
  • Receiving or have received daclizumab in the previous 4-18 months
  • Receiving or have received daclizumab less than (\<) 24 hours pretransplant and additional courses every other week
  • Single organ recipients (kidney only)
  • Previous vaccination with tetanus toxoid (TT) prior to transplant
  • Receiving a maintenance immunosuppression regimen of a calcineurin inhibitor, mycophenolate mofetil, and prednisone (or equivalent corticosteroid)

You may not qualify if:

  • Experienced rejection within 3 months of receiving study vaccinations and/or treated with lymphocyte preparation or methylprednisolone to reverse suspected acute rejection within 3 months of receiving study vaccinations
  • Received any vaccine within 30 days of receiving study vaccinations
  • Received plasmapheresis treatment or growth hormone treatment since transplant
