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.

本II期研究评估自体肿瘤浸润淋巴细胞LN-145或LN-145-S1治疗复发或难治性卵巢癌、三阴性乳腺癌、未分化甲状腺癌、骨肉瘤及其他骨/软组织肉瘤的疗效。LN-145由患者肿瘤中采集并扩增的T细胞制成;LN-145-S1采用改良工艺,选择特定T细胞亚群。这些T细胞可识别、靶向并杀伤肿瘤细胞。
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.
