About
This phase I trial studies the safety and best dose of ex-vivo activated lymph node lymphocytes (X-ACT) as well as how well the immune system responds to X-ACT treatment in participants with stage IIIC-IV melanoma. X-ACT treatment involves removing a participant's lymph node(s) close to a melanoma tumor. These lymph nodes contain special kind of cells (called T cells) which can be activated (getting the cells to start up certain responses in the immune system) outside of the body in an approved laboratory. The activated T cells are then injected back into the same participant using an i.v. to help the participant's immune system to target melanoma. The participant will undergo regular blood testing to determine whether the X-ACT treatment has resulted in changes to the immune system and also whether the T cells which were given back to the patient persist in the blood stream over time. In addition, the effect of the X-ACT treatment on the growth or shrinkage of the participant's melanoma will be measured.
Full description
PRIMARY OBJECTIVES:
I. Assess the safety and toxicity profile of repeated infusions of ex-vivo activated tumor-draining lymphocytes (X-ACT) in participants with advanced melanoma.
SECONDARY OBJECTIVES:
I. Assess the feasibility of multiple infusions of X-ACT. II. Assess the effect of dose and schedule on immunologic parameters using two novel biomarkers.
III. Observe the clinical outcomes of participants receiving X-ACT therapy.
OUTLINE: This is a dose-escalation study.
STEP 1: Participants undergo lymph node biopsy for collection of at least one melanoma-draining lymph node (MDLN). MDLN cells will then be cryopreserved into aliquots until they are needed to generate an activated T cell culture.
STEP 2: Cryopreserved lymph node cells are thawed and then undergo activation with anti-cluster of differentiation (CD)3/anti-CD28 microbeads. The cultures then undergo expansion over 14-18 days in the presence of recombinant human interleukin-2 and anti-vascular endothelial growth factor antibody. The activated X-ACT cells are then transferred i.v. into the same participant from which they were derived with no additional therapy.

Inclusion criteria
STEP 1
Participants must have a histologic diagnosis of melanoma either from a primary or metastatic site; Participants with brain metastases must have completed radiation therapy >30 days prior to enrollment
Participants must have American Joint Committee on Cancer (AJCC) stage IIIC unresected or IV disease
Patients with non-measureable or measurable disease are eligible. Measurable lesions are defined as those that can be accurately measured in at least one dimension (longest diameter for non-nodal lesions and short axis for nodal lesions to be recorded) as ≥ 20 mm by chest x-ray, as ≥ 10 mm with CT scan, or ≥ 10 mm with calipers by clinical exam. Malignant lymph nodes, to be considered pathologically enlarged and measurable, must be ≥ 15 mm in short axis when assessed by CT scan (CT scan slice thickness recommended to be no greater than 5 mm). At baseline and in follow-up, only the short axis will be measured and followed.

In the opinion of the investigator, participant must be medically fit to undergo surgical procedure
Participants treated with prior chemotherapy, cytotoxic chemotherapy, radiation, biotherapy, or any investigational agent > 30 days prior to lymph node removal are eligible
Women of child-bearing potential must agree to use adequate contraception (double barrier method of birth control or abstinence) during participation in the study; should a woman become pregnant or suspect that she is pregnant while she or her partner is participating in this study, she should inform the treating physician immediately
Participants must be disease free of prior invasive malignancies for > 5 years, with the exception of curatively treated basal cell or squamous cell carcinoma of the skin or cancer in-situ of the cervix
Participants must be able to understand and willing to sign a written informed consent document
