What side effects are associated with this type of intervention?

Genetically modified T-cell therapies for pancreatic cancer, such as mesothelin-specific T-cells (FH-TCR-Tᴍsʟɴ), can cause side effects including cytokine release syndrome, which may result in fever, fatigue, and multiorgan dysfunction, including acute kidney injury. Other potential side effects include electrolyte abnormalities, immune-related adverse events like acute tubulointerstitial nephritis, and general chemotherapy-related toxicities such as nausea, vomiting, and myelosuppression.

What prior FDA approvals exist?

The FDA has approved several treatments for pancreatic cancer, including chemotherapy regimens like FOLFIRINOX (a combination of leucovorin, fluorouracil, irinotecan, and oxaliplatin) and gemcitabine-based therapies. While there are no specific FDA approvals for genetically modified T-cell therapies targeting mesothelin in pancreatic cancer, similar approaches in other cancers include CAR-T cell therapies targeting CD19 in hematologic malignancies. These therapies involve modifying a patient's T-cells to better recognize and attack cancer cells, akin to the investigational mesothelin-specific T-cells (FH-TCR-Tᴍsʟɴ) being studied for metastatic pancreatic ductal adenocarcinoma.

What other types of research exist?

Promising novel alternatives to Mesothelin-specific T-cells (FH-TCR-Tᴍsʟɴ) for pancreatic cancer patients include: 1) Immune checkpoint inhibitors such as pembrolizumab (anti-PD-1) and nivolumab (anti-PD-1), which have shown efficacy in various cancers and are being explored in pancreatic cancer. 2) CAR-T cell therapies targeting other antigens like Claudin 18.2, which is overexpressed in pancreatic cancer cells. 3) Bispecific antibodies that can engage T-cells to target pancreatic cancer cells, such as those targeting CD3 and a tumor-specific antigen. 4) Oncolytic virotherapy, which uses genetically modified viruses to selectively infect and kill cancer cells while stimulating an anti-tumor immune response.

Study Summary

This trial is testing a new treatment for pancreatic cancer that has spread to other parts of the body. The treatment is a type of immunotherapy, which uses the patient's own T cells that have been genetically modified to better recognize and target cancer cells. The trial will test what dose of the treatment is safe and effective, as well as how it works with chemotherapy.

Who is the study for?

Adults with metastatic pancreatic ductal adenocarcinoma who've had at least one systemic therapy can join. They must have a life expectancy over 3 months, be willing to undergo tumor biopsies, and not have received recent treatments that could interfere. Participants need properly functioning major organs, no severe autoimmune diseases or organ transplants, and agree to use contraception.Check my eligibility

What is being tested?

The trial is testing FH-TCR-Tᴍsʟɴ T-cells designed to target mesothelin on cancer cells combined with chemotherapy drugs like cyclophosphamide and fludarabine. The goal is to find the safest dose that helps these modified T-cells better attack the tumor cells in patients with advanced pancreatic cancer.See study design

What are the potential side effects?

Potential side effects include reactions related to immune system activation such as inflammation in different body parts, symptoms from cell infusion like fever or chills, and typical chemotherapy-related issues such as nausea, fatigue, low blood counts increasing infection risk.

Other Research

The most common treatments for pancreatic cancer include chemotherapy, targeted therapy, and immunotherapy. Chemotherapy drugs like cyclophosphamide and fludarabine work by killing rapidly dividing tumor cells or stopping their growth. Targeted therapies, such as those inhibiting specific mutations like KRAS G12C, aim to block pathways essential for cancer cell survival. Immunotherapy, including mesothelin-specific T-cells (FH-TCR-Tᴍsʟɴ), involves genetically modifying a patient's T-cells to recognize and kill tumor cells expressing mesothelin, a protein overexpressed in pancreatic cancer. This approach is significant for pancreatic cancer patients as it offers a personalized treatment option that harnesses the body's immune system to target and eliminate cancer cells, potentially leading to more effective and durable responses.
