What is the purpose of this trial?

This trial tests a new treatment for individuals with pancreatic cancer that has returned or isn't responding to other treatments. The research uses a special immune cell therapy called EGFR FPBMC (EGFRBi-armed fresh PBMC), which involves infusing lab-activated cells to combat the cancer. Participants will initially receive these infusions weekly, then every two weeks. Ideal candidates have tried at least one chemotherapy treatment and have pancreatic cancer that cannot be surgically removed or cured but remains stable for at least three months. As a Phase 1 trial, this research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this new therapy.

Do I have to stop taking my current medications for this trial?

The trial protocol does not specify if you need to stop taking your current medications. However, you should discuss your current medications with the trial team to ensure they don't interfere with the study.

Is there any evidence suggesting that this treatment is likely to be safe for humans?

Research has shown that the EGFR FPBMC treatment for pancreatic cancer appears promising in terms of safety. In a study involving 16 patients with advanced pancreatic cancer, this treatment proved safe, with manageable side effects. EGFR FPBMC is a type of immunotherapy, which uses the body's immune system to fight cancer, potentially enhancing its safety profile.

However, detailed safety information remains limited. As this trial is still in the early stages, further research is necessary to confirm these findings. The treatment's current safety profile supports the continuation of more trials, but prospective participants should consult their doctor about potential risks and benefits. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Unlike the standard treatments for pancreatic cancer, like chemotherapy and radiation, EGFR FPBMC uses a completely different approach by harnessing the body's own immune cells. Researchers are excited about EGFR FPBMC because it involves collecting and activating fresh peripheral blood mononuclear cells to specifically target and fight pancreatic cancer cells. This method is unique because it directly uses patients' immune cells, potentially offering a more personalized and targeted attack against the cancer. This innovative approach has the potential to not only slow disease progression but also enhance the body's natural immune response to cancer.

What evidence suggests that EGFR FPBMC might be an effective treatment for pancreatic cancer?

Research has shown that EGFR FPBMC treatment, which participants in this trial will receive, might help with pancreatic cancer. In earlier studies, this treatment extended patients' lives by an average of 4.9 months. Patients who responded well had lower levels of EGFR on their cancer cells, suggesting the treatment might slow cancer growth. Studies also indicate that the treatment is safe and manageable for people with advanced pancreatic cancer. Overall, EGFR FPBMC appears to be a promising option for treating this challenging cancer. ^{1 2 3 4 5}

What Are the Treatments Tested in This Trial?

Interventions

• EGFR FPBMC

Trial Overview The study tests EGFR FPBMC, a treatment involving immune cells armed with a bispecific antibody targeting cancer cells. Participants will receive this through an IV once weekly for 8 weeks, then every two weeks for another 8 doses to assess safety and potential effectiveness.

How Is the Trial Designed?

Group I: EGFR Fresh Peripheral Blood Mononuclear Cells Experimental Treatment 1 Intervention

Participants will undergo apheresis to collect cells to make EGFR fresh peripheral blood mononuclear cells (FPBMC). These cells will be activated in the lab to fight against pancreas cancer. About 3-4 days after apheresis, participants will start receiving infusions of EGFR FPBMC. Throughout treatment, participants will have blood taken for labs, to check disease status and also to look at immune response. Study treatment will stop if the participant has disease progression. Participants that have disease progression after the first 8 infusions may receive chemotherapy and then continue study treatment with the other 8 infusions.

The phase I/II trial involving 7 patients with advanced pancreatic cancer demonstrated that infusions of bispecific antibody armed activated T cells (BATs) were safe, with no dose-limiting toxicities observed, and the maximum tolerated dose was successfully reached.

Patients experienced a median time to progression of 7 months and a median overall survival of 31 months, with some showing complete responses after treatment, indicating that BAT infusions can effectively stimulate the immune system against pancreatic cancer.

The phase I clinical trial involving 16 patients with metastatic pancreatic carcinoma demonstrated that CAR T-EGFR cell therapy is safe, with manageable side effects such as fever and nausea, and resulted in partial responses in 4 patients and stable disease in 8 patients for 2-4 months.

The treatment led to a median overall survival of 4.9 months and showed a decrease in EGFR expression on tumor cells in patients who responded positively, indicating that CAR T-EGFR cells can effectively target and shrink metastatic lesions.

In pancreatic ductal adenocarcinoma (PDAC), a significant portion of tumor-infiltrating T cells exhibit an exhausted phenotype characterized by high levels of PD-1 and TIGIT, indicating a challenging immune environment for effective therapy.

Combining anti-PD-1 and TIGIT blockade has been shown to enhance T cell activity, suggesting that this dual approach could improve immunotherapy outcomes in PDAC patients.

Pancreatic ductal adenocarcinoma (PDAC) shows resistance to traditional immune checkpoint therapies (ICTs), but combining agonist 41BB and antagonist LAG3 ICTs can enhance survival and boost antitumor immunity by improving T cell activity and reducing immunosuppressive cells.

The most effective treatment strategy involved a triple therapy combining T cell-activating ICTs with a CXCR1/2 inhibitor, which led to durable complete responses in PDAC, suggesting a promising new approach for this challenging cancer.

Adoptive cell therapy using tumor-infiltrating lymphocytes (TIL) or TCR gene-modified T cells targeting mutant KRAS neo-antigens shows promise for treating advanced pancreatic ductal adenocarcinoma (PDAC), a cancer that has seen little progress in treatment for over 40 years.

To enhance the production of TILs specific to mutant KRAS, researchers developed a novel approach using tandem mini gene-modified autologous T cells (TMG-T) as artificial antigen-presenting cells, successfully generating TIL cultures that are specifically reactive to the mKRAS (G12V) mutation.

Adoptive cell therapy using CAR-engineered T cells shows promise as a safe treatment option for patients with pancreatic ductal adenocarcinoma, indicating it may help restore effective immune surveillance against tumors.

Early results suggest that CAR T cells not only have the ability to attack tumors directly but also stimulate the body's own immune system to fight cancer, enhancing overall anti-tumor responses.

Immunotherapy Shows Promise in Pancreatic Cancer. [2020]

Bispecific antibody armed activated T cells (EGFR BATs) can effectively target and kill drug-resistant pancreatic cancer cells, enhancing their sensitivity to chemotherapy drugs like gemcitabine and cisplatin.

The study suggests that priming resistant cancer cells with EGFR BATs may modulate the expression of ABC transporters, which are linked to drug resistance, thereby improving the effectiveness of subsequent chemotherapy treatments.
