the requirements of the study, have provided written informed consent as evidenced by

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 that
included a non-myeloablative or myeloablative chemotherapy regimen.

LN-144 or other study drugs:
- NMA-LD preconditioning regimen (cyclophosphamide, mesna, and fludarabine)
- Proleukin®, aldesleukin, IL-2.

≥ 14 days, there are no symptomatic brain lesions, and that the patient does not
require ongoing corticosteroid treatment.
- - Patients who are on chronic systemic immunosuppressive therapy except for those
requiring steroid therapy for management of adrenal insufficiency; these patients may
receive no more than 10 mg of prednisone or its equivalent daily.
Transient use of
steroids, e.g. in the perioperative period, is not an exclusion.
- - Patients who are pregnant or breastfeeding.

- - Patients with any irreversible wall movement abnormalities are excluded.
- - Patients who have a smoking history or signs or symptoms of 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; and non-melanoma skin cancer that has been adequately treated).
- - Active, uncontrolled systemic infections, including COVID-19, within 30 days of
surgery or NMA-LD.
An uncomplicated bacterial UTI treated successfully with symptom
resolution is not an exclusion.
- - Participation in another clinical study with an investigational product within 21 days
of the initiation of NMA-LD.
Eligibility Designation for Lymphodepletion. Patients meeting eligibility criteria above between Day -21 and Day -8 prior to the planned
initiation of lifileucel will be enrolled to the therapeutic portion of the protocol.
All patients' eligibility criteria, including repeating cardiopulmonary function tests as
necessary, will be reassessed within several days prior to the scheduled lymphodepletion in
all cases.
Prior to beginning the NMA-LD preparative regimen the following requirements must be met:
- - Patients must meet all eligibility criteria at the time of NMA-LD.
- - Full resolution of any active infection should be documented.
- - Critical evaluation of changes in cardiovascular, respiratory, renal, coagulopathy, or
immune problems and other major illnesses that may have developed or worsened must be
documented.
- - Patients with symptomatic, recurrent, pleural effusions that require drainage should
not proceed to lymphodepletion without prior placement of a temporary in-dwelling
pleural drain.
- - All active medical issues must be addressed by Investigator or designee.
Re-evaluation
with additional imaging or testing may be required. Subsequent delays of lymphodepletion up to 14 days due to logistical issues such as
production of lifileucel and/or major weather events will not constitute protocol
violations and out of window assessments will not need to be repeated unless there is a
change in clinical status.
