Status Conditions Phase Study ID
Recruiting Pancreatic Cancer Phase III 8028
NCT01836432
Summary

Unfortunately, despite the best clinical efforts and breakthroughs in biotechnology, most patients diagnosed with pancreatic cancer continue to die from the rapid progression of their disease. One primary reason for this is that the disease is typically without symptoms until significant local and/or distant spread has occurred and is often beyond the chance for cure at the time of the diagnosis. The lack of any treatment to substantially increase long term survival rates is reflected by the poor outcomes associated with this disease, specifically time to disease progression and overall survival.

However, another important part of the body is now being looked at as a target for therapy against this disease - the immune system. Scientists have clearly shown that pancreatic tumor cells produce a number of defective proteins, or express normal proteins in highly uncharacteristic ways, as part of this cancer. In some cancers, these abnormalities can cause an immune response to the cancer cells much in the way one responds to infected tissue. In progressive cancers however, the immune system fails to effectively identify or respond to these abnormalities and the cancer cells are not attacked or destroyed for reasons not yet fully understood. This clinical trial proposes a new way to stimulate the immune system to recognize pancreatic cancer cells and to stimulate an immune response that destroys or blocks the growth of the cancer.

This new method of treatment helps the immune system of pancreatic cancer patients to "identify" the cancerous tissue so that it can be eliminated from the body. As an example, most people are aware that patients with certain diseases may require an organ transplant to replace a damaged kidney or heart. After receiving their transplant, these patients receive special drugs because they are at great danger of having an immune response that destroys or "rejects" the transplanted organ. This "rejection" occurs when their immune system responds to differences between the cells of the transplanted organ and their own immune system by attacking the foreign tissue in the same way as it would attack infected tissue. When the differences between foreign tissues and the patient's body are even larger, as with the differences between organs from different species, the rejection is very rapid, highly destructive, and the immunity it generates is longlasting. This is called hyperacute rejection and the medicine used to immunize patients in this protocol tries to harness this response to teach a patient's immune system to fight their pancreatic cancer just as the body would learn to reject a transplanted organ from an animal.

To do this, HyperAcute-Pancreas immunotherapy contains human pancreatic cancer cells that contain a mouse gene that marks the cancer cells as foreign to patient's immune systems. The immune system therefore attacks these cancer cells just as they would attack any truly foreign tissue, destroying as much as it can. Additionally, the immune system is stimulated to identify differences (aside from the mouse gene) between these cancer cells and normal human tissue as foreign. This "education" of the immune system helps treat the patient because pancreatic cancer cells already present in a treated patient are believed to show some of the same differences from normal tissue as the modified pancreatic cancer cells in the product. Due to these similarities, the immune system, once "educated" by the HyperAcute-Pancreas immunotherapy, identifies the patient's cancer as foreign and attacks.

The chemotherapy combination to be used in this study has been shown to improve survival in advanced pancreatic cancer and is being combined with an experimental pancreatic cancer immunotherapy that stimulates the immune system to recognize and attack the cancer. One goal of this study is to determine whether chemotherapy and immunotherapies can work cooperatively to increase anti-tumor effects to levels beyond what would be seen with either treatment alone.

In this experimental study, all patients are given a strong combination of anti-tumor chemotherapies while some patients are also given injections of an immunotherapy drug consisting of two types of pancreatic cancer cells that we have modified to make them more easily recognized and attacked by the immune system. We propose to test this new treatment protocol in patients with locally advanced pancreatic cancer to demonstrate that treatment with the immunotherapy increases the time until the tumor progresses or increases overall survival when given in combination with the current standard of care therapy for this disease.

Eligibility Criteria (must meet the following to participate in this study)
  • A histological diagnosis of adenocarcinoma of the pancreas confirmed by pathology.
  • Patients must have borderline resectable or locally advanced unresectable pancreatic cancer with no metastatic spread as determined by a baseline diagnostic CT scan with intravenous contrast (or MRI). CT should be performed according to a defined pancreas protocol such as triphasic cross-sectional imaging with thin slices. Optimal multi-phase technique including a non-contrast phase plus arterial, pancreatic parenchymal and portal venous phase of contrast enhancement with thin cuts (3mm) throughout the abdomen is preferred. Studies must be evaluated by a radiologist and/or surgeon and deemed borderline resectable or locally advanced unresectable as defined per the NCCN Practice Guidelines in Oncology V2.2012, as:
  • Borderline resectable- Tumors considered borderline resectable are defined as follows:
    1. No distant metastases
    2. Venous involvement of the SMV/portal vein demonstrating tumor abutment with impingement and narrowing of the lumen, encasement of the SMV/portal vein but without encasement of the nearby arteries, or short-segment venous occlusion resulting from either tumor thrombus or encasement but with suitable vessel proximal and distal to the area of vessel involvement, allowing for safe resection and reconstruction
    3. Gastroduodenal artery encasement up to the hepatic artery with either short segment encasement or direct abutment of the hepatic artery without extension to the celiac axis.
    4. Tumor abutment of the SMA not to exceed greater than 180 degrees of the circumference of the vessel wall.
  • Tumors considered to be unresectable due to local advancement include an absence of distant metastases as well as:
    1. Head: Greater than 180 degrees SMA encasement or any celiac abutment or unreconstructible SMV/portal occlusion or aortic invasion or encasement.
    2. Body: Greater than 180 degrees SMA or celiac encasement or unreconstructible SMV/portal occlusion or aortic invasion.
    3. Tail: SMA or celiac encasement greater than 180 degrees.
    4. Nodal status: Involvement of lymph nodes beyond the field of resection should be considered unresectable due to distant spread and therefore not eligible for this protocol.
  • Eastern Cooperative Oncology Group (ECOG) Performance Status ≤ 1.
  • Serum albumin ≥ 2.0 gm/dL.
  • Expected survival ≥ 6 months.
  • Adequate organ function including:
    1. Marrow: WBC ≥3000/mm^3 and platelets ≥100,000/mm^3.
    2. Hepatic: serum total bilirubin ≤ 2 mg/dL, ALT (SGPT) and AST (SGOT) ≤3 x upper limit of normal (ULN) at time of enrollment. If a patient has elevated liver function tests at the time of initial presentation or develops them during work-up and they are the result of a mechanical obstruction of biliary drainage by tumor compression or invasion, a biliary drain may be placed as described in NCCN Practice Guidelines in Oncology V2.2012. If drainage allows for the liver function tests to come within inclusion criteria, the patient may be enrolled.
    3. Renal: serum creatinine (sCr) ≤2.0 x ULN, or creatinine clearance (Ccr) ≥30 mL/min.
  • Patients must have the ability to understand the study, its inherent risks, side effects and potential benefits and be able to give written informed consent to participate. Patients may not be consented by a durable power of attorney (DPA).
  • All subjects of child producing potential must agree to use contraception or avoidance of pregnancy measures while enrolled on study and receiving the experimental product, and for one month after the last immunization.
