programmed cell death 1 + selected cell therapy with durvalumab (medi4736) and tremelimumab in metastatic melanoma

Conditions: Malignant Melanoma

Summary: the primary objective of this pilot study is to assess the feasibility of mobilizing pd-1+ t cells to the peripheral blood after a single treatment with tremelimumab/durvalumab in patients with treatment naïve metastatic melanoma.

the primary objective of this pilot study is to assess the feasibility of mobilizing programmed cell death (pd-1)+ t cells to the peripheral blood after a single treatment with tremelimumab/durvalumab in patients with treatment naïve metastatic melanoma. secondary objectives are to evaluate the safety and clinical activity of administering a regimen of pd-1+ selected tumor infiltrating lymphocytes (til)/(interleukin) il-2, using a cell product manufactured in the yale advanced cell therapy laboratories and assess for clinical activities in subjects with metastatic melanoma who are not responding or have progressed after receiving first-line therapy with 1 cycle of tremelimumab/durvalumab followed by 3 cycles of ipilimumab/nivolumab followed by nivolumab monotherapy as maintenance treatment. exploratory objective are to: 1. assess the number of pd-1+ t cells in the tumor microenvironment before and after a single treatment with tremelimumab/durvalumab. 2. conduct a preliminary assessment of the tcr clonotypes present in pd1+ cluster of differentiation 8 (cd8)+ cells (4-1bb, lag-3, tim-3, pd-1) versus pd1-cd8+ t-cells early in the expansion cultures and compare to clonotypes late in the final product and in peripheral blood lymphocytes (pbl) 1 and 2 months post infusion. 3. assess neoantigens present in resected tumor and correlate t cell specificity for neoantigens from til and peripheral blood mononuclear cell (pbmc) populations stratified by pd-1 expression in these cell populations.

patients. women will be considered post-menopausal if they have been amenorrheic for 12 months without an alternative medical cause. the following age-specific requirements apply: * women \<50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatments and if they have luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution or underwent surgical sterilization (bilateral oophorectomy or hysterectomy). * women ≥50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatments, had radiation-induced menopause with last menses \>1 year ago, had chemotherapy-induced menopause with last menses \>1 year ago, or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy or hysterectomy). * patient is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow up. * must have a life expectancy of at least 12 weeks. exclusion criteria: received prior treatment for metastatic melanoma * received prior cell transfer therapy that included non-myeloablative or ablative chemotherapy * received anti pd-1 immune therapy within prior 6 months * any contraindication to neutropenia or thrombocytopenia for up to 2 weeks (no active major infection, no site of active, clinically significant bleeding) * concurrent major medical illnesses * any form of immunodeficiency * severe hypersensitivity to any of the agents used in this study * contraindications for il-2 administration * involvement in the planning and/or conduct of the study (applies to both astrazeneca staff and/or staff at the study site) * participation in another clinical study with an investigational product during the last 4 weeks * concurrent enrolment in another clinical study, unless it is an observational (non-interventional) clinical study or during the follow-up period of an interventional study * any unresolved toxicity nci ctcae grade ≥2 from previous anticancer therapy with the exception of alopecia, vitiligo, and the laboratory values defined in the inclusion criteria * patients with grade ≥2 neuropathy will be evaluated on a case-by-case basis after consultation with the study physician. * patients with irreversible toxicity not reasonably expected to be exacerbated by treatment with durvalumab, tremelimumab, ipilimumab or nivolumab may be included only after consultation with the study physician. * any concurrent chemotherapy, investigational product (ip), biologic, or hormonal therapy for cancer treatment. concurrent use of hormonal therapy for non-cancer-related conditions (e.g., hormone replacement therapy) is acceptable. * major surgical procedure (as defined by the investigator) within 28 days prior to the first dose of ip. note: local surgery of isolated lesions for palliative intent is acceptable. * history of allogenic organ transplantation. * active or prior documented autoimmune or inflammatory disorders (including inflammatory bowel disease \[e.g., colitis or crohn's disease\], diverticulitis \[with the exception of diverticulosis\], systemic lupus erythematosus, sarcoidosis

vitiligo or alopecia * patients with hypothyroidism (e.g., following hashimoto syndrome) stable on hormone replacement * any chronic skin condition that does not require systemic therapy * patients
