Fast TILs to Treat Metastatic Pleural Effusions From Epithelial or Mesothelial Primary Tumors

This is a first-in-human Phase 1 trial of short-term expanded pleural T cells to treat cancer metastatic to the pleura. Expanded cells will be delivered intrapleurally in combination with intrapleural IL-2, administered at a dose that ensures high local concentration while minimizing systemic exposure.

Ancillary studies conducted in conjunction with the trial will leverage drained pleural effusions collected before and after intervention to determine why the intervention is succeeding or failing.

Inclusion criteria

• Patients with symptomatic, biopsy-proven malignant to the pleura, or mesothelioma with pleural effusions. Patients must have received and be refractory to available standard of care (SOC) therapy specific to their cancer type and must have exhausted or failed available standard of care with clinical benefit.
• Patients will be ≥ 18 and < 80 years of age.
• Female patients of childbearing potential must have a negative urine or serum pregnancy test and if sexually active must use an acceptable method of contraception, including abstinence, a barrier method (diaphragm or condom), an injectable contraceptive (such as Depo-Provera), or an oral contraceptive. Active contraception should continue for at least 12 months after ACT administration.

Male participants must be willing to practice birth control from the time of enrollment on this study and for 4 months after receiving the preparative regimen.

• Cardiac ejection fraction ≥ 0.45 by MUGA or echocardiography.
• No requirement for supplemental oxygen and no dyspnea immediately after effusion drainage.
• ECOG Performance Status 0 or 1.
• Patients must have an expected survival > 12 weeks.
• Patients must be able to comprehend the risks and methods used in this clinical trial and independently consent to participate.
• Patients must consent to collection of demographic and clinical data.

Exclusion criteria

• Infection with HIV and active viral replication. Patients with an undetectable viral load on Anti-retroviral Therapy (ART) can be considered for participation on this protocol.
• Infection with hepatitis B and active viral replication.
• Infection with hepatitis C and active viral replication.
• Patients currently being treated for bacterial, fungal or viral infection.
• Documented myocardial infarction within 6 months of study participation and/or symptomatic coronary artery or valvular disease or uncontrolled arrhythmia.
• Investigational drug use within 30 days before effusion collection.
• Cytotoxic anti-cancer or radiation therapy administration within 2 weeks of effusion collection. The exclusion does not apply to patients receiving monoclonal antibody therapy targeting immune checkpoint molecules.
• Corticosteroid therapy > 10 mg of prednisone (biological equivalent) daily within 2 weeks before effusion collection.
• Immunosuppressive therapy that cannot be stopped for 4 weeks prior to effusion collection as deemed by the prescribing physician.
• Laboratory abnormalities that indicate clinically significant hematological, hepatobiliary, or renal disease:

AST/SGOT > 2.0 times the upper limit of normal ALT/SGPT > 2.0 times the upper limit of normal Total bilirubin > 2.0 times the upper limit of normal, unless patient has Gilbert Syndrome (>3.0 times the upper limit of normal) Hemoglobin < 8 gm/dL or dependent upon transfusion to maintain ≥ 8 gm/dL White blood cell count < 2,000/mm3 Platelet count < 100,000/mm3 or dependent upon transfusion to maintain ≥ 100,000 mm3 Creatinine > 2.0 times the upper limit of normal or calculated creatinine clearance ≤ 40 mL/min.

• Pregnant or lactating females.
• Prior solid organ transplantation
• Patients who, in the opinion of the Investigator, will be non-compliant with study schedules or procedures.
• Patients who belong to a vulnerable population such as the homeless, the developmentally disabled and prisoners or have any condition that impairs their ability to provide informed consent or comply with study schedules or procedures.
• Patients with documented anaphylaxis as a result of penicillin allergy.
