Clinical Study to Assess Efficacy and Safety of LN-145/LN-145-S1 (Autologous Centrally Manufactured Tumor Infiltrating Lymphocytes) Across Multiple Tumor Types
Clinical Study to Assess Efficacy and Safety of LN-145/LN-145-S1 (Autologous Centrally Manufactured Tumor Infiltrating Lymphocytes) Across Multiple Tumor Types
This phase II trial studies how well autologous tumor infiltrating lymphocytes LN-145 (LN-145) or LN-145-S1 works in treating patients with ovarian cancer, triple negative breast cancer (TNBC), anaplastic thyroid cancer, osteosarcoma, or other bone and soft tissue sarcomas that do not respond to treatment (refractory) or that has come back (relapsed).
LN-145 is made by collecting and growing specialized white blood cells (called T-cells) that are collected from the patient's tumor. LN-145-S1 is made using a modified process that chooses a specific portion of the T-cells. The T cells may specifically recognize, target, and kill the tumor cells.
PRIMARY OBJECTIVE:
I. To evaluate efficacy using objective response rate (ORR) using Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1 in each cohort.
SECONDARY OBJECTIVES:
I. Determine the disease control rate (DCR) within and across cohorts. II. Determine the duration of response (DOR). III. Determine progression-free survival (PFS) and overall survival (OS). IV. Further characterize the safety profile of adoptive cell therapy with tumor infiltrating lymphocytes (TIL) across multiple tumor types.
EXPLORATORY OBJECTIVES:
I. Establish duration of tumor-infiltrating lymphocyte (TIL) persistence. II. Compare the molecular and immunological features of tumors before and after TIL therapy.
III. Prospectively evaluate the existing immunotherapy response criteria (immune-related [ir]RECIST) as the best response assessment tool for TIL therapy among a diverse group of solid tumors.
IV. To investigate TIL attributes (CD8 percentage [%], CD27 and CD28 expression) and correlation with response to therapy.
V. Assess tumor marker (CA-125) response in patients who produce this tumor marker.
VI. To assess Health-Related Quality of Life (HRQOL).
OUTLINE: Patients are assigned to 1 of 2 cohorts.
THYROID CANCER COHORT: Patients receive cyclophosphamide intravenously (IV) over 2 hours on days -7 and -6, fludarabine IV over 15-30 minutes daily on days -5 to -1, autologous tumor infiltrating lymphocytes LN-145 IV over 45 minutes on day 0 and aldesleukin IV over 30 minutes on days 1-4 for up to 6 doses.
ICI OVARIAN CANCER, OSTEOSARCOMA, Triple Negative Breast Cancer, or OTHER BONE AND SOFT TISSUE SARCOMAS COHORT: Within 2-4 weeks prior to surgery, patients receive a single dose of nivolumab IV over 30 minutes, followed by a single dose of ipilimumab IV over 30 minutes Patients receive cyclophosphamide IV over 2 hours on days -7 and -6, fludarabine IV over 15-30 minutes daily on days -5 to -1, LN-145-S1 IV over 45 minutes on day 0 and aldesleukin IV over 30 minutes on days 1-4 for up to 6 doses. Within 12 weeks after receiving LN-145-S1, patients receive nivolumab IV over 30 minutes every 4 weeks in the absence of disease progression or unacceptable toxicity.
For cohorts treated without immune checkpoint inhibitors, completion of treatment is defined as having received any volume of LN-145/LN-145-S1 infusion followed by at least 1 dose of adjuvant IL-2. For cohorts treated with TIL + ICI, completion of treatment will correspond to the last dose of nivolumab or IL2 (if the subject is deemed unsuitable to receive adjuvant nivolumab). Patients are followed up at 18 weeks, 6, 9, 12, 18 and 24 months, then every 3 months for at least 3 years.

Exclusion Criteria:
Active or uncontrolled intercurrent illness, including but not limited to ongoing or active infections, coagulation disorders or other major medical illnesses of the cardiovascular, respiratory or immune system. Principal investigator (PI) or his/her designee shall make the final determination regarding appropriateness of enrollment.
Patients with active viral hepatitis.
Patients who have a left ventricular ejection fraction (LVEF) < 45% at screening.
Patients with a history of prior adoptive cell therapies.
Persistent prior therapy-related toxicities greater than grade 2 according to Common Toxicity Criteria for Adverse Events (CTCAE) version (v)4.03, except for peripheral neuropathy, alopecia, or vitiligo prior to enrollment.
Primary immunodeficiency.
History of organ or hematopoietic stem cell transplant.
Chronic steroid therapy, however prednisone or its equivalent is allowed at =< 10 mg/day.
Patients who are pregnant or nursing.
Presence of a significant psychiatric disease, which in the opinion of the principal investigator or his/her designee, would prevent adequate informed consent.
History of clinically significant autoimmune disease including active, known, or suspected autoimmune disease. Subjects with resolved side effects from prior checkpoint inhibitor therapy, vitiligo, psoriasis, type 1 diabetes or resolved childhood asthma/atopy would be an exception to this rule. Subjects that require intermittent use of bronchodilators or local steroid injections would not be excluded. Subjects with hypothyroidism stable on hormone replacement or Sjogren's syndrome will not be excluded.
History of clinically significant chronic obstructive pulmonary disease (COPD), asthma, interstitial lung disease, or other chronic lung disease.
History of a second malignancy (diagnosed in the last 5 years). Exceptions include basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or in situ cervical cancer that has undergone potentially curative therapy. For the thyroid cancer cohort, subjects have a higher likelihood of prior cancers. Therefore, for this cohort, history of prior thyroid cancer or other indolent cancers is not considered exclusionary if in the opinion of the treating physician such cancers are indolent or unlikely to affect the overall prognosis based on the active thyroid cancer.
History of known active central nervous system metastases and/or carcinomatous meningitis. Subjects with previously treated brain metastases may participate provided they are stable (without evidence of progression by imaging for at least four weeks prior to the first dose of trial treatment and any neurologic symptoms have returned to baseline), have no evidence of new or enlarging brain metastases, and are not using steroids for at least 7 days prior to initiation of lymphodepletion.
Has received a live vaccine within 30 days prior to the initiation of lymphodepletion.
Patients who have a contraindication to or history of hypersensitivity reaction to any components or excipients of the TIL therapy or the other study drugs: non-myeloablative-lymphodepletion (NMA-LD) (cyclophosphamide, mesna, and fludarabine); IL-2; antibiotics of the aminoglycoside group (i.e., streptomycin, gentamicin); any component of the TIL infusion product formulation including human serum albumin (HSA), IL-2, and dextran-40, nivolumab or ipilimumab.
Any other condition that in the investigator's judgement would significantly increase the risks of participation.
