- Registration Number
- NCT06190249
- Lead Sponsor
- James Isaacs, MD
- Brief Summary
The purpose of this study is to evaluate the efficacy of adjuvant adoptive cell therapy (ACT) via infusion of LN-144 (autologous TIL) followed by interleukin-2 (IL-2) after a nonmyeloablative lymphodepletion (NMA-LD) preparative regimen, followed by Pembrolizumab.
- Detailed Description
Primary:
• To evaluate the efficacy of LN-144 with adjuvant Pembrolizumab in Stage IIIb-d melanoma patients as assessed by 6 and 12-month relapse-free survival (RFS)
Secondary:
* To further evaluate the efficacy of LN-144 with adjuvant Pembrolizumab in Stage IIIb-d melanoma patients using overall survival (OS) and distant metastasis-free survival

- 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 must have a washout period ≥ 21 days from prior anti-cancer therapy(ies) to the start of the planned NMA-LD pre-conditioning regimen.
- Patients must be ≥ 18 years of age at the time of consent.
- Patients must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 and an estimated life expectancy of ≥ 3 months in the opinion of the Investigator.
- Patients must have the following hematologic parameters:• Absolute neutrophil count (ANC) ≥ 1000/mm3, •Hemoglobin (Hb) ≥ 9.0 g/dL, •Platelet ≥ 100,000/mm3

- 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.

Participant has an LVEF < 45% and is New York Heart Association (NYHA) Class 1. For participants ≥ 60 years of age OR who have a history of clinically relevant cardiac disease, no irreversible wall movement abnormality is demonstrated on a cardiac stress test (or equivalent local standard stress test). Participants with an abnormal cardiac stress test may be considered for study participation if they have adequate ejection fraction and cardiology clearance with approval of the Investigator.
-
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.,
- Patients who are unable to walk a distance of at least 80% predicted for age and sex or demonstrates evidence of hypoxia at any point during the test (SpO2 < 90%) are excluded.
-
Patients who have had another primary malignancy within the previous three (3) years (with the exception of carcinoma in situ of the breast, cervix, or bladder; localized prostate cancer; non-melanoma skin cancer that has been adequately treated; or other cancers that in the opinion of the investigator do not place the subject at a significantly higher risk).
