TILs & Low-Dose IL-2 Therapy Following Cyclophosphamide and Fludarabine in Pleural Mesothelioma Patients

January 8, 2023 updated by: University Health Network, Toronto

Phase I/II Study Evaluating the Infusion of Tumor-Infiltrating Lymphocytes (TILs) & Low-Dose Interleukin-2 (IL-2) Therapy Following a Preparative Regimen of Non-myeloablative Lymphodepletion Using Cyclophosphamide & Fludarabine in Patients With Malignant Pleural Mesothelioma

This is a phase I and II clinical study for patients with malignant pleural mesothelioma (a type of cancer affecting the lining of the lung). Patients will receive an infusion (given by vein) of autologous tumor infiltrating lymphocytes (TILs). TILs are a type of white blood cells that recognizes tumor cells and enter them which causes the tumor cells to break down.

Prior to the cell infusion, patients will receive a two drugs cyclophosphamide and fludarabine to prepare the body to receive the TILs. After cell infusion, patients will receive low-dose interleukin-2 therapy. This study will see how safe and useful this regimen is in treating malignant pleural mesothelioma.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The investigational infusion product consists of autologous, in vitro-expanded tumor-infiltrating lymphocytes (TILs). The target number of cells for infusion is between 1 x 1010 and 1.6 x 1011. The cells are given intravenously over a 20-30 minute infusion.

Prior to infusion of TILs, patients will receive a preparative regimen of cyclophosphamide (60 mg/kg/day x 2 days intravenously) and fludarabine (25 mg/m2/day x 5 days intravenously).

After the cell infusion, patients will receive low-dose interleukin-2 (IL-2) therapy (125,000 IU/kg/day subcutaneously for 2 weeks with a 2 day break between each week. The goal for the total number of doses is 9-10).

Because confusion is a possible side effect of IL-2 administration, a Durable Power of Attorney will be signed by the patient to identify a surrogate to make decisions if a patient becomes unable to make decisions.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Description

Inclusion Criteria:

  • Able to sign and date the informed consent form.
  • Must have measurable stage I-IV malignant pleural mesothelioma at the time of investigational treatment.
  • May have 3 or fewer asymptomatic brain metastases.
  • Patient age: ≥ 18 years.
  • Clinical performance status of ECOG 0 or 1.
  • Life expectancy > 3 months from the date of consent.
  • Laboratory analyses of tumor-infiltrating lymphocytes (TILs) from the patient must demonstrate that the TILs are suitable for use in protocol treatment
  • More than 30 days has elapsed since any prior systemic therapy at the time of the cell infusion, or more than six weeks since prior nitrosurea therapy. All toxicities must have recovered to a grade 1 or less. Patients may have undergone minor surgical procedures with the past 3 weeks, as long as all toxicities have recovered to grade 1 or less

  • Women of child-bearing potential must have a negative pregnancy test. Patients of both genders must be willing to practice birth control during treatment and for 6 months post completion of IL-2 treatment.
  • Patients must have adequate respiratory function in the opinion of the treating thoracic physician

Exclusion Criteria:

  • Ongoing or prior use systemic steroid therapy within 4 weeks before the TILs infusion will be excluded.
  • Known HIV positive patients will be excluded.
  • Active hepatitis B or hepatitis C, syphilis, or HTLV will be excluded.
  • Must not have any active systemic infections, coagulation disorders or other active major medical illnesses of the cardiovascular, respiratory or immune system, uncontrolled psychiatric disorders, or other conditions that may affect compliance with the trial.
  • Must have no active underlying cardiac illnesses defined by positive stress test, LVEF <40% or ongoing life threatening arrhythmias.
