About this study
Official title: Leuprolide Acetate to Enhance Immune Function Post-Autologous Stem Cell Transplantation
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.
Read the detailed 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.
- Being tested
- Leuprolide acetate depot (LAD) 11.25 mg 3 Month, Matched placebo
- Keywords
- Bone marrow transplantation, Hematopoietic stem cell transplantation, Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma
- Medical subject headings
- Hodgkin Disease, Lymphoma, Non-Hodgkin, Multiple Myeloma, Lymphoma, Mantle-Cell
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Leuprolide acetate depot (LAD) 11.25 mg 3 MonthDrug
Also called Lupron
LAD intramuscular injection 11.25 mg, 3 month duration. To stimulate immune response, a subcutaneous key limpet hemocyanin (KLH) vaccination injection (1 mg) was administered at Month 6.
Matched placeboDrug
Matched placebo intramuscular injection, 3 month duration. To stimulate immune response, a subcutaneous key limpet hemocyanin (KLH) vaccination injection (1 mg) was administered at Month 6.
| Study group | Role | What they receive |
|---|---|---|
| LAD 11.25 mg 3 Month Depot | Experimental | Three intramuscular injections LAD 11.25 mg 3 Month treatment administered approximately 3 months apart. Receives: Drug: Leuprolide acetate depot (LAD) 11.25 mg 3 Month |
| Placebo Comparator | Placebo comparator | Three intramuscular injections of matched placebo administered approximately 3 months apart. Receives: Drug: Matched placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: Month 6 prevaccination (baseline) and Month 7 postvaccination
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.
Measured: Month 6 prevaccination (baseline) and Month 7 postvaccination
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.
Measured: Month 6 prevaccination (baseline) and Month 7 postvaccination
Secondary outcomes (2)
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. Mayo Medical Clinic. http://www.mayomedicallaboratories.com/test-catalog/Clinical+and+Interpretive/87959. Accessed 17 MARCH 2010
The change from baseline is defined as posttransplant TREC/100,000 CD4+ cells minus pretransplant TREC /100,000 CD4+ cells.
Measured: Pretransplant and posttransplant (Month 12)
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. 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 CD8+ cells, an assessment of T cell recovery and immune response is obtained. Mayo Medical Clinic. http://www.mayomedicallaboratories.com/test-catalog/Clinical+and+Interpretive/87959. Accessed 17 MARCH 2010
The change from baseline is defined as posttransplant TREC/100,000 CD8+ cells minus pretransplant TREC /100,000 CD8+ cells.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Leuprolide acetate depot (LAD) 11.25 mg 3 Month in people with Hodgkin Disease and Lymphoma, Non-Hodgkin, run by Abbott at 4 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 13 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 6 May 2010. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 6 May 2010). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
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 (time frame: Month 6 prevaccination (baseline) and Month 7 postvaccination). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 May 2010.
