What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing a new treatment that uses a patient's own immune cells, grown in a lab, to fight advanced melanoma that cannot be removed by surgery or has spread. The goal is to see if this approach is safe and effective. Using a patient's own immune cells to fight cancer has shown promise in treating advanced melanoma.

Will I have to stop taking my current medications?

The trial requires that any systemic therapy, including anti-cancer monoclonal antibodies, must be stopped at least 4 weeks before starting the lymphodepleting therapy. Additionally, participants taking systemic steroid therapy or immunosuppressive medications are excluded from the trial.

What safety information is available for the combination of TBio-4101, chemotherapy, and IL-2 in treating skin cancer?

Interleukin-2 (IL-2) has been studied extensively and is known to cause reversible but often severe side effects, such as low blood pressure, swelling, and kidney issues, especially at higher doses. These side effects require careful monitoring and supportive care in a critical-care setting. Other common side effects include fever, fatigue, nausea, and muscle pain, but these are generally manageable and reversible.12345

How is the TBio-4101 + Chemo + IL-2 treatment for skin cancer different from other treatments?

This treatment is unique because it combines TBio-4101, a form of interleukin-2 (a protein that boosts the immune system), with chemotherapy and tumor-infiltrating lymphocytes (TILs), which are immune cells that target cancer cells. This combination aims to enhance the body's immune response against skin cancer, potentially offering greater effectiveness than using these components separately.36789

What evidence supports the effectiveness of the treatment TBio-4101 + Chemo + IL-2 for skin cancer?

Research shows that tumor-infiltrating lymphocytes (TILs) combined with interleukin-2 (IL-2) can lead to tumor regression in melanoma, a type of skin cancer. This suggests that the combination of TILs and IL-2, as part of the treatment, may be effective in treating skin cancer.3791011

Are You a Good Fit for This Trial?

This trial is for adults aged 18-75 with unresectable or metastatic melanoma, including various types like cutaneous and ocular melanoma. Participants must have adequate organ function, an ECOG status of 0 or 1, and be willing to practice birth control. Those with treated brain metastases, a negative pregnancy test (if applicable), and the ability to sign consent can join. Excluded are pregnant women, those with severe heart issues or immunodeficiency disorders, active infections requiring IV antibiotics, history of severe allergies to study drugs, certain lung function impairments, autoimmune diseases needing steroids in the past 6 months.

What Are the Treatments Tested in This Trial?

Interventions

  • Cyclophosphamide
  • Fludarabine
  • Interleukin-2
  • TBio-4101
Trial Overview The trial tests TBio-4101 therapy using tumor infiltrating lymphocytes after lymphodepleting chemotherapy followed by interleukin-2 (IL-2) in participants with advanced melanoma. It aims to assess if this approach is feasible and safe while also evaluating its effectiveness against the cancer.
How Is the Trial Designed?
1Treatment groups
Experimental Treatment
Group I: Infusion of TBio-4101 TILExperimental Treatment4 Interventions
TBio-4101 is a tumor-infiltrating lymphocyte (TIL) product: participants tumor tissue is surgically removed and immune T-cells are taken out of the tumor and multiplied, or grown, in the laboratory. TIL product infused intravenously over 20 to 30 minutes within 2 to 4 days after the last dose of fludarabine Participants will also receive: * Cyclophosphamide dose 60 mg/kg/day for 2 days administered IV in 250 mL dextrose 5% in water infused simultaneously with Mesna 15 mg/kg/day delivered over 1 hour per day for 2 days. Fludarabine 25 mg/m2/day is delivered by intravenous piggyback daily over 15-30 minutes for 5 days. * Interleukin-2 (IL-2)- will be given to participants through IV after they receive the infusion of the TIL. IL-2 is administered at a dose of 600,000 IU/kg (based on actual body weight) IV every 8-12 hours beginning within 24 hours of TIL infusion for a maximum of 6 doses.

Published Research Related to This Trial

Transducing tumor-infiltrating lymphocytes (TILs) with a truncated IL-2 gene allows these cells to produce high levels of IL-2 and proliferate independently, suggesting a promising approach for enhancing adoptive immunotherapy in melanoma treatment.
Although the TILs can initially proliferate autonomously due to the autocrine loop created by IL-2 production, the expression of the IL-2 gene decreases after 2 to 3 weeks, indicating a need for strategies to maintain IL-2 expression over time.
Enhanced interleukin-2 production in human tumor-infiltrating lymphocytes engineered by 3'-truncated interleukin-2 gene.Yamaue, H., Kashmiri, SV., De Filippi, R., et al.[2019]
In a study involving 69 patients with metastatic melanoma, unselected young tumor-infiltrating lymphocytes (TILs) showed a higher response rate (35%) compared to CD8(+)-enriched TILs (20%), although the difference was not statistically significant.
The research suggests that unselected young TILs may be more effective and easier to prepare than CD8(+)-enriched TILs, as the latter did not demonstrate superior therapeutic potency despite being more complex to produce.

In a five-year trial involving 49 patients with relapsing metastatic stage III melanoma, the combination of tumor-infiltrating lymphocytes (TIL) and interleukin-2 (IL-2) did not show a statistically significant improvement in disease-free survival compared to a control group that received no treatment.
The safety profile of TIL + IL-2 was good, with no significant differences in relapse rates or mortality between the treatment and control groups, suggesting that while the treatment was safe, it did not provide the expected benefits over abstention.
