Clinical Trial Summary

Phase 2 study, conducted in patients with Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, or mantle cell lymphoma undergoing high-dose chemotherapy and autologous stem cell transplantation.

Description:

This Phase 2 study will be conducted in patients with Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, or mantle cell lymphoma undergoing high-dose chemotherapy and autologous stem cell transplantation. Patients will be randomized to receive either LAD 11.25 mg 3 Month treatment or placebo and all patients will be vaccinated with KLH 6 months posttransplant. Patients will be evaluated to determine if the rate of immunologic recovery in the LAD group is enhanced compared with the placebo group.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Mean Change From Baseline in IgM Response (Mcg/mL) Before Keyhole Limpet Hemocyanin (KLH) Vaccination at Month 6 and After KLH Vaccination at Month 7 in Patients Who Received LAD or Placebo	Patients received a subcutaneous injection of KLH vaccine 1 month after subjects received the third injection of LAD or placebo. Serum immunoglobulin IgM antibodies were determined by enzyme-linked immunosorbent assay (ELISA). Baseline is defined as the IgM concentration before the KLH vaccination. Change from baseline was calculated as the IgM value postvaccination minus the IgM value at prevaccination.	Month 6 prevaccination (baseline) and Month 7 postvaccination	No
Primary	Mean Change From Baseline in IgG1 Response (Mcg/mL) Before KLH Vaccination at Month 6 and After KLH Vaccination at Month 7 in Patients Who Received LAD or Placebo	Patients received a subcutaneous injection of KLH vaccine 1 month after subjects received the third injection of LAD or placebo. Serum immunoglobulin IgG1 antibodies were determined by enzyme-linked immunosorbent assay (ELISA). Baseline is defined as the IgG1 concentration before the KLH vaccination. Change from baseline was calculated as the IgG1 value postvaccination minus the IgG1 value at baseline.	Month 6 prevaccination (baseline) and Month 7 postvaccination	No
Primary	Mean Change From Baseline in Interferon Gamma Response (Spots/1 Million Cells) Before KLH Vaccination at Month 6 and After KLH Vaccination at Month 7 in Patients Who Received LAD or Placebo	Patients received a subcutaneous injection of KLH vaccine 1 month after subjects received the third injection of LAD or placebo. Interferon gamma was determined by enzyme-linked immunosorbent spot-forming cell (ELISpot). Baseline is defined as the interferon gamma concentration obtained before the KLH vaccination. Change from baseline was calculated as the interferon gamma value postvaccination minus the interferon gamma value at baseline.	Month 6 prevaccination (baseline) and Month 7 postvaccination	No
Secondary	Mean Change From Baseline in T Cell Excision Circles (TREC) Per 100,000 CD4+ Cells to Final Visit in Patients Treated With LAD (11.25 mg) or Placebo After Transplant	CD4+ cells are a type of T cell. T cells are produced in the thymus and thymic function can be determined by TREC. By counting the number of TRECs present (only 1 copy per cell) within a population of CD4 cells, an assessment of T cell recovery and immune response is obtained.

Secondary	Mean Change From Baseline in TREC Per 100,000 CD8+ Cells to Final Visit in Patients Treated With LAD (11.25 mg) or Placebo After Transplant	CD8+ cells are a type of T cell.
