Vaccination of Patients With Stage IV Melanoma With Dendritic Cells Generated Ex Vivo From Monocytes and Loaded With Heat Treated Killed Allogeneic Melanoma Cells
A novel dendritic cell vaccine has been developed at the Baylor Institute for Immunology
Research (BIIR). Pre-clinical studies have found that this dendritic cell vaccine is more
efficient in inducing a tumor specific immunity than other dendritic cell vaccines. Further
studies in the BIIR have been done with dendritic cells that were loaded with killed
melanoma cells from a melanoma cell line treated with heat before loading. Both studies have
shown that DCs manufactured in this novel way were more efficient in priming the melanoma
specific CD8+ cells. Thus, the strategy for this clinical trial will be to test recent
laboratory findings in the clinical setting. An additional objective of the study will be to
determine the effectiveness of a frozen vaccine product which differs from previous vaccines
that were manufactured "fresh".
This clinical trial will evaluate the novel dendritic cell vaccine in patients with Stage IV
melanoma. The trial will accrue a total of 30 subjects. The primary goal of this trial will
be to test the safety/tolerability/feasibility of the vaccine preparation and the rate of
objective clinical response. A 15% objective response rate will be accepted in patients who
have failed previous therapy with IL-2 and/or dacarbazine (DTIC) and/or temozolomide which
are standard treatments for patients with malignant melanoma.
Each subject will be given 7 initial injections in a fixed dose amount. The first 4 doses
will be given at 2-week intervals (Weeks 0, 2, 4 and 6); the last 3 doses will be given at
4-week intervals (Weeks 10, 14, and 18). Those patients who exhibit stable disease, partial
response or complete response after 7 injections will be given 4 more vaccinations. Each of
these additional 4 vaccinations will be given 3 months apart (Weeks 36, 48, 72 and 96).
Scans and re-staging tests will be performed at scheduled intervals throughout the study.
Inclusion Criteria:
- Stage M1a, M1b, M1c biopsy proven metastatic melanoma
- Failure of at least one prior chemotherapy regimen of DTIC and/or temozolomide
with/without interleukin-2 (IL-2).
- Karnofsky performance status greater than/equal to 80%.
- Measurable metastatic lesions by physical exam or scans.
- Acceptable CBC and blood chemistry results
- Adequate renal function.
- Written informed consent.
Exclusion Criteria:
- Patients who have received more than 8 cycles of chemotherapy for metastatic
melanoma.
- Patients who have received chemotherapy less than 4 weeks before beginning the trial.
- Patients who have received interferon (IFN) alpha-2b or granulocyte-monocyte
colony-stimulating factor (GM-CSF) less than 4 weeks before beginning the trial.
- Patients who have received high-dose IL-2 less than 4 weeks before beginning the
trial.
- Patients with a history of central nervous system (CNS) metastatic melanoma.
- More than 5 hepatic lesions or any hepatic lesion larger than 5 cm.
- Baseline serum LDH greater than 4 times the upper limit of normal.
- Patients who are HIV positive.
- Patients who are pregnant.
- Patients who have received corticosteroids or other agents less than 4 weeks before
beginning the trial.
- Patients with asthma, angina pectoris or congestive heart failure.
- Patients with autoimmune diseases such as lupus erythematosus, rheumatoid arthritis
or thyroiditis.
- Patients with active infections including viral hepatitis.
- Patients with a history of any other neoplastic disease less than 5 years ago
(carcinomas in situ of the cervix and basal/squamous cell carcinomas of the skin,
however, can be admitted to the study).
