Melanoma Clinical Trial

A Study of LN-144 in People With Metastatic Melanoma to the Brain

Summary

The researchers are doing this study to find out whether it is practical to treat study participants' metastatic melanoma tumors with LN-144. Some practical steps the study doctors will study are whether LN-144 can be made quickly for each participant, if enough tumor samples are collected for the study therapy or whether there are complications during the surgical procedure. We will also look at whether LN-144 is a safe and effective treatment for melanoma tumors in the brain.

Eligibility Criteria

Inclusion Criteria:

Must have a confirmed diagnosis of metastatic non-uveal melanoma.
At least one (1) intracranial lesion measuring 5-30mm visible on gadaliniumenhanced MRI to be used as target lesion defined in mRECIST. Multiple intracranial lesions are allowed as long as all lesions are 30mm in size or less.
Subjects must be free of neurologic signs and symptoms related to metastatic brain lesions and must not have required or received systemic corticosteroid therapy in the 10 days prior to beginning protocol therapy.
Must have received prior anti-PD-1 (with or without anti-CTLA-4) for metastatic melanoma with radiographic and/or pathologic progression of disease. If there is a BRAF V600E/K mutation, the patient must have received prior BRAF+MEK targeted therapy with demonstrated progression of disease.
One (1) lesion at least 1.5cm in size (solitary or aggregate) available for TIL harvesting that has not undergone prior embolization or RT in prior 3 months unless subsequent growth is demonstrated (at least 0.5cm).
Patients must be ≥ 18 years of age at the time of consent.

Platelet ≥ 100,000/mm^3

Patients must have adequate organ function:

Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 3 times the upper limit of normal (≤ 3 × ULN); patients with liver metastasis ≤ 5 × ULN

Total bilirubin ≤ 2 mg/dL
Patients with Gilbert's syndrome must have a total bilirubin ≤ 3 mg/dL

Patients must be seronegative for the following:

Human immunodeficiency virus (HIV)-1 or HIV-2 antibodies
Hepatitis B antigen (HBsAg), hepatitis B core antibody (anti- HBc), or hepatitis C antibody (HCV Ab). Patients with acute or chronic hepatitis infections may be enrolled if the viral load by polymerase chain reaction (PCR) is undetectable with/without active treatment.
Syphilis (EIA Ig screen followed by Rapid Plasma Reagin [RPR] test or venereal disease research laboratory [VDRL] test if screen is positive)
Cytomegalovirus (CMV) PCR assay (IgM antibody titer if indicated); and Epstein-Barr virus (EBV) IgM or PCR assay indicating active infection
Herpes simplex virus (HSV)-1 and HSV-2 PCR assay
Patients who are HSV PCR assay positive will need to receive appropriate treatment and become PCR assay negative prior to starting the NMA-LD pre-conditioning regimen
Patients must have a negative COVID-19 PCR test within 72 hours of surgical excision as well as prior to receipt of pre-conditioning cytotoxic therapy. Anyone with prior COVID-19 infection must be asymptomatic for >30 days.
Patients must have a washout period ≥ 28 days (or 5 half-lives for oral medications) from prior anti-cancer therapy(ies) to the start of the planned NMALD pre-conditioning regimen.
Palliative radiation therapy is permitted so long as it does not involve lesions being selected for TIL harvest or the lesion is the single site of intracranial metastasis such that response to LN-144 could not be assessed. Washout is not required if all related toxicities have resolved to ≤ Grade 1 as per CTCAE v 5.0.

Patients must have recovered from all prior anti-cancer therapy-related adverse events (AEs) to ≤ Grade 1 (per Common Terminology Criteria for Adverse Events [CTCAE] v 5.0), except for alopecia or vitiligo, prior to enrollment.

Patients with documented ≥ Grade 2 diarrhea or colitis as a result of previous treatment with immune checkpoint inhibitor(s) must have been asymptomatic for at least 6 months and/or had a normal colonoscopy post-immune checkpoint inhibitortreatment, by visual assessment, prior to tumor resection.
Patients with immunotherapy-related endocrinopathies (e.g. hypothyroidism, hypopituitarism) stable for at least 6 weeks and controlled with hormonal replacement (including prednisone < 10 mg/day or equivalent) are allowed.
Previous surgical procedure(s) is/are permitted provided that wound healing has occurred, all complications have resolved, and at least 14 days have elapsed (for major operative procedures) prior to the tumor resection.

Patients of childbearing potential (or female partners of male participants) must be willing to take the appropriate precaution to avoid pregnancy or fathering a child for the duration of the study and practice an approved, highly effective method of birth control during treatment and for 12 months after their last dose of IL-2. Approved methods of birth control are as follows:

Combined (estrogen and progesterone containing) hormonal birth control associated with inhibition of ovulation: oral, intravaginal, transdermal
Progesterone-only hormonal birth control associated with inhibition of ovulation: oral, injectable, implantable
Intrauterine device (IUD)
Intrauterine hormone-releasing system (IUS)
Bilateral tubal occlusion
Vasectomized partner
True sexual abstinence when this is in line with the preferred and usual lifestyle of the patient. Periodic abstinence (eg, calendar ovulation, symptothermal, post-ovulation methods) is not acceptable
Patients (or legally authorized representative) must have the ability to understand the requirements of the study, have provided written informed consent as evidenced by signature on an ICF approved by an Institutional Review Board/Independent Ethics Committee (IRB/IEC), and agree to abide by the study restrictions and return to the site for the required assessments, including the OS Follow-up Period.

Exclusion Criteria:

Patients who have received an organ allograft or prior cell transfer therapy within the past 20 years that included a non-myeloablative or myeloablative chemotherapy regimen.

Patients with any irreversible wall movement abnormalities are excluded.

Patients who have obstructive or restrictive pulmonary disease and have a documented forced expiratory volume in 1 second (FEV1) of ≤ 60% of predicted normal:

If a patient is not able to perform reliable spirometry due to abnormal upper airway anatomy (i.e., tracheostomy), a 6-minute walk test may be used to assess pulmonary function.
