HEPATIC IMMUNOTHERAPY FOR METASTASES (HITM)
PHASE I TRIAL FOR PATIENTS WITH ADENOCARCINOMA
LIVER METASTASES (NCT01373047)
Click here to enroll in this trial.
The purpose of this study is to collect data on the safety and potential effectiveness
of 2nd generation designer T cells delivered into the hepatic arterial circulation
in patients with liver metastases expressing the CEA tumor marker. Designer T cells
are prepared by collecting white blood cells from the participant, and then modifying
these cells in the laboratory so that they recognize the tumor antigen, CEA. These
modified cells are then given back into the participant so that they can attack
and kill tumor cells. We hypothesize that regional delivery of the designer T cells
directly into the hepatic artery will minimize systemic toxicity and optimize the
changes for therapeutic effect.
T cells have the power to destroy malignant cells under certain conditions, as demonstrated
by the rare spontaneous remissions of cancer. However, the endogenous T cell response
to cancer fails in the vast majority of patients and the tolerogenic conditions
within the liver may pose additional immunologic barriers for those with intrahepatic
metastases. We modify patient T cells to kill malignant cells based on their expression
of tumor antigens using antibody-defined recognition. We will achieve this by preparing
chimeric IgCD28TCR genes in mammalian expression vectors to yield "designer T cells"
from normal patient cells. Prior studies in model systems demonstrated that recombinant
IgCD28TCR (see figure above) could direct modified T cells to respond to antigen
targets with IL2 secretion, cellular proliferation, and cytotoxicity - the hallmarks
of an effective, self-sustaining immune response.
The present trial will test the regional infusion of anti-CEA designer T cells,
given via the hepatic artery using a percutaneous approach (see adjacent figure).
This is an intra-patient dose escalation trial, where patients will receive three
doses over the course of six weeks. Doses are 10^8, 10^9 and 10^10 modified T cells.
Patients are monitored for safety and response. Patients are on-study for one month
after dosing. Patients undergo phlebotomy or leukapheresis from which peripheral
blood mononuclear cells are purified. T cells are activated in culture, and then
transduced with retrovirus expressing the anti-CEA IgCD28TCR. Cells are expanded
in culture and returned to the patient by percutaneous hepatic artery infusion at
specific cell doses. Prior to the first dose, each patient will undergo diagnostic
angiography to verify suitable arterial anatomy. Three doses per patient are planned
at 2 week intervals.

GASTROINTESTINAL STROMAL TUMOR (GIST) OPEN GIST TRIAL (NCT00867113)
We are pleased to announce our participation in an important trial addressing the
duration of imatinib mesylate (Gleevec®) therapy for patients with gastrointestinal
stromal tumors (GIST). As you know, the ability of imatinib to lower the risk of
recurrence following surgical removal of GIST is profound. Yet, the appropriate
duration of imatinib therapy following resection is not yet determined. The Roger
Williams Cancer Center is pleased to offer access to this national trial, which
addresses this important clinical question. This is a Phase II, non-randomized,
open-label, multi-center study conducted in the USA. The primary endpoint is to
evaluate the use of long term adjuvant imatinib mesylate in patients at significant
risk for recurrence following complete resection of primary GIST. A total of 133
adult patients will be enrolled. Participants will take 400 mg of imatinib mesylate
daily by mouth for a total of 5 years. At the conclusion of the treatment period,
patients will be followed for 5 years for survival, recurrence, and quality of life.
The drug is available to enrolled patients for 5 years at no cost. Enrollment is
competitive and the trial will be closed after the target is reached.
& Exclusion Criteria Highlights:
Age ≥ 18; Histological GIST diagnosis and CD117 (KIT)
positive tumor; Primary GIST (any site) ≥ 2cm & ≥5 mitoses/50 HPF OR non-gastric
primary GIST ≥ 5cm Complete gross resection of primary GIST within 12 weeks of enrollment;
No evidence of metastatic GIST on CT or MRI ECOG performance status of 0 or 1; All
prior malignancies treated with potentially curative therapy and free of recurrence
for ≥ 3 years; Patients with grade III/IV cardiac problems are excluded; Patients
being treated with warfarin are excluded.
PANCREAS CANCER OPEN PANCREATIC CANCER TRIAL (NCT00569387)
We are pleased to announce our participation in an important trial for patients
with pancreas adenocarcinoma. As you know, even for those patients with pancreatic
adenocarcinoma who are able to undergo potentially curative resection, the majority
with recur and die of disease. Our presently available systemic treatments are inadequate.
We and others believe that immunotherapy holds great promise for the treatment of
pancreatic cancer. The present trial offers an innovative approach to a daunting
disease - the HyperAcute®-Pancreatic Cancer Vaccine in combination with chemotherapy
and chemoradiotherapy. A vaccine consisting of an inactivated pancreatic cancer
cell line expressing murine glycoproteins will be given in conjunction with gemcitabine
and chemoradiotherapy following resection. This is a Phase II, non-randomized, multi-center
study. The primary endpoint is time to recurrence. Secondary endpoints are the extent
of the immune response induced by the vaccine and overall survival. A total of 71
adult patients will be enrolled. Participants will undergo five cycles of treatment
following surgery, including vaccination X 5, chemotherapy X 5, and chemoradiotherapy.
Inclusion & Exclusion Criteria Highlights:
A histological diagnosis of adenocarcinoma
of the pancreas. AJCC Stage I or II Pancreatic carcinoma; Patients must have undergone
surgical resection for the tumor and extent of resection must be either R0 (complete
resection) or R1 (grossly negative but positive microscopically margins of resection);
Eastern Cooperative Oncology Group (ECOG) Performance Status ≤ 2; Expected survival
≥ 6 months. Serum albumin ≥ 2.0 gm/dL; Patients with
other malignancies within five years, unless the probability of recurrence of the
prior malignancy is <5%,are excluded; Patients with active metastases are excluded.
