Innovative Research and Clinical Trials
Many advances in the diagnosis and treatment of cancer patients have occurred because
of pioneering research studies called “clinical trials.” Participation in innovative
research and clinical trials is an important commitment of Hoag Cancer Center in
its mission to provide the highest quality cancer treatment and management.
Hoag’s cancer research team is composed of physicians, scientists, nurses and other
medical professionals who are committed to providing leading-edge care for cancer
patients by providing access to nationally recognized clinical trials using new
or unique treatments through research protocols.
The following are the disease-specific clinical trials currently being studied at
Hoag Cancer Center. Please click on any of the following for details, or call the
nursing management team at Hoag Clinical Trials at 949/764-5543.

Protocol: Brain LAK vs Gliadel® wafers for patients with Glioblastoma
Title: Randomized Phase II Trial of Intralesional Lymphokine Activated Killer Cells
or Polifeprosan 20 with Carmustine Implant (Gliadel® Wafer) as Consolidation Therapy
after Primary Treatment of Newly Diagnosed Resectable Glioblastoma
Principal Investigator: Robert Dillman, MD
Sponsor: Hoag Hospital
Description:
The purpose of this study is to determine how effective the study drug is in delaying
a recurrence of a patient’s brain tumor and helping patients to live longer. Up
to 80 patients with a diagnosis of glioblastoma (grade 4 anaplastic astrocytoma)
may be enrolled in this trial. Half (about 40) of the patients will be randomized
(selection of treatment by chance, like flipping a coin) to receive one of the following
treatments, which will be placed in the brain at the time of surgery (craniotomy):
1) An experimental treatment, using Lymphokine Activated Killer (LAK) cells OR
2) FDA approved treatment, using implantable Gliadel® wafers
There is an equal chance of being assigned to either treatment group. There is no
placebo (sugar or fake pill) used in this study.
This trial is an option for patients if they are:
- 18 years of age or older with newly diagnosed glioblastoma for which primary treatment
consisting of surgery, radiation therapy, and temozolomide chemotherapy has been
administered;
- Willing to undergo a second brain surgery (craniotomy) at Hoag Hospital to place
the study drug into the brain cavity (the neurosurgeon investigator involved in
the study MUST feel that the second surgical procedure can be performed);
- In good physical health;
- Other eligibility criteria apply
The study agents, described below, will be given as part of the treatment plan that
follows the initial therapy in those patients whose disease is felt to be under
control.
LAK cells: A patient’s white blood cells are collected with a special machine
(like donating blood) and treated outside the body with an immune-stimulating chemical
called interleukin-2 (IL-2), which induces these cells to increase in number and
increase their anticancer killing function. It is hoped that these cells placed
into the area of the brain tumor will kill any residual tumor cells.
Gliadel® wafers: These are small, thin, dime-sized wafers that are absorbed
by the body, and contain the cancer chemotherapeutic drug, carmustine (BCNU). Up
to eight wafers can be implanted in the cavity where the tumor resided. Once implanted,
Gliadel® wafers slowly dissolve, releasing high concentrations of chemotherapy into
the tumor site.
The treatment is administered only at Hoag Hospital in Newport Beach, CA, and is
not a treatment for patients who have recurrent brain cancer.

Name of Study: HCC 06-03: Randomized Phase II Trial of Autologous
Vaccines Consisting of Adjuvant GM-CSF plus Proliferating Tumor Cells versus GM-CSF
plus Dendritic Cells Loaded with Proliferating Tumor Cells in Patients with Metastatic
Melanoma
Disease Type: Metastatic Melanoma, Stage 3 or 4
Abbreviated Name: MAC-VAC
Sponsor: Hoag Hospital
Principal Investigator: Robert Dillman, MD, FACP
Description: In this clinical trial, a patient’s own (‘autologous’) melanoma
tumor tissue cells are grown in a laboratory, treated with radiation (so they cannot
keep growing), and then given back to the patient in a series of 8 vaccinations.
It is a randomized, open label study designed to determine whether 1 of 2 autologous
vaccines have better patient outcomes; the study does not involve a placebo treatment.
Eligible patients will be randomized to 1 of 2 tumor cell vaccines:
- 50% of patients will receive the Tumor Cell Vaccine.
This vaccine consists of a patient’s own tumor cells that have been treated with
radiation, and added to GM-CSF (a commercially available immune stimulating substance)
for injection.
- 50% of patients will receive the Dendritic Cell Vaccine.
This vaccine is the same as the Tumor Cell vaccine above, except that a patient’s
own dendritic cells (specialized immune cells) have been added.
This experimental treatment may be an option for patients at least 16 years of age
who have been diagnosed with Stage 3 or 4 melanoma. Such patients may have tissue
removed and sent to Hoag Cancer Center for development of a tumor cell line by the
Cell Biology Laboratory. A cell line can be established about 65-70% of the time,
and the process of growing the tumor cells typically takes 2 to 11 months; so this
is not a treatment that can be made available quickly. If successfully grown, and
if patients consent to therapy and are otherwise eligible, patients are randomized
to receive either vaccine. Dendritic Cell Vaccine patients undergo a procedure following
randomization called ‘pheresis’, in which immune cells are obtained from the blood
stream and converted into dendritic cells in the laboratory.
Vaccine Therapy: Vaccines are injected into the soft tissue of the skin (subcutaneously)
once a week for 3 weeks, then once a month for up to 5 months (total of 6 months
of treatment). Patients will receive a maximum of 8 vaccination doses. The treatment
must be given at Hoag Hospital Cancer Center. This is not a treatment for patients
who have growing brain metastases, or for patients with wide spread melanoma that
is rapidly progressing despite other therapies. We plan to randomize 200 patients,
with 100 in each autologous vaccine arm.
Patient Eligibility:
- Karnofsky Performance Status (KPS) of 70 to 100%
- No active central nervous system metastases at the time
of randomization
- No diagnosis of any other invasive cancer within the
past five years
- Age ≥ 16 years and in satisfactory medical condition
- No anticancer therapy for 3 weeks prior to randomization
- No active infection or underlying cardiac disease
- No known autoimmune disease
- Serum pregnancy test must be negative for women of childbearing
potential
- Patients may have received any or all of the following:
surgery, radiation therapy, chemotherapy, biotherapy, including GM-CSF, and prior
vaccine therapy.
- Other eligibility criteria apply
