- 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 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, •Estimated creatinine clearance (eCrCl) = 40
mL/min using the Cockcroft-Gault formula at Screening, •Total bilirubin = 2 mg/dL,
•Patients with Gilbert's syndrome must have a total bilirubin = 3 mg/dL
- 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 melanoma of uveal/ocular origin.
- Patients who have a history of hypersensitivity to any component or excipient of
LN-144 or other study drugs:
- NMA-LD preparative regimen (cyclophosphamide, mesna, and fludarabine),
- Proleukin®, aldesleukin, IL-2,
- Pembrolizumab,
- Antibiotics (ABX) of the aminoglycoside group (i.e., streptomycin, gentamicin);
except those who are skin-test negative for gentamicin hypersensitivity,
- Any component of the LN-144 infusion product formulation including dimethyl
sulfoxide (DMSO), human serum albumin (HSA), IL-2, and dextran-40.
- Patients with symptomatic and/or untreated brain metastases (of any size and any
number).
- Patients who are on chronic systemic steroid 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.
- Patients who are pregnant or breastfeeding.
- Patients who have active medical illness(es) that would pose increased risk for study
participation, including: active systemic infections requiring systemic ABX,
coagulation disorders, or other active major medical illnesses of the cardiovascular,
respiratory, or immune systems.
- Patients must have a negative syphilis assay (per local standard, e.g., rapid plasma
reagin [RPR], venereal disease research laboratory [VDRL]) and be seronegative for the
human immunodeficiency virus (HIV1 and HIV2 antibody titers). Patients with positive
serology for hepatitis B virus surface antigen (HBsAg), hepatitis B core antibody
(anti-HBc) or hepatitis C virus (anti-HCV) indicating acute or chronic infection must
have the corresponding polymerase chain reaction (PCR) assay; patients may be enrolled
if the viral load by PCR is undetectable with/without active treatment. Additional
serology testing may be required depending on local prevalence of certain viral
exposures
- Patients who have any form of primary immunodeficiency (e.g., severe combined
immunodeficiency disease [SCID] and acquired immunodeficiency syndrome [AIDS])
- Patients who have received a live or attenuated vaccination within 28 days prior to
the start of NMA-LD pre-conditioning regimen.
- 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).
- Active infections, including COVID-19, within 30 days
- Participated in another clinical study with an investigational product within 21 days
of the initiation of treatment.
