简要总结
Background:
Exome sequencing can identify certain gene mutations in a person's tumor. This can then be used to create cancer treatments. In this study, researchers will make a treatment called a messenger ribonucleic acid (mRNA) vaccine. The vaccine might cause certain tumors to shrink.
Objective:
To see if the mRNA vaccine is safe and can cause metastatic melanoma or epithelial tumors to shrink.
Eligibility:
People 18-70 years old with metastatic melanoma or epithelial cancer
Design:
Participants will be screened under protocol 99-C-0128.
Participants will provide samples under protocol 03-C-0277:
Participants will provide a piece of their tumor from a previous surgery or biopsy.
Participants will have leukapheresis: Blood is removed through a needle in one arm and circulated through a machine that takes out the white blood cells. The blood is then returned through a needle in the other arm.
Participants will have many tests:
Scans and x-rays
Heart and lung function tests
Blood and urine tests
Participants will receive the mRNA vaccine every 2 weeks for up to 8 weeks. They will get the vaccine as an injection into the upper arm or thigh. They may receive a second course of vaccines if the study doctor determines it is needed.
Participants will have follow-up visits approximately 2 weeks after their final vaccine, then 1 month later, then every 1-2 months for the first year, and then once a year for up to 5 years. Each visit may take up to 2 days and include:
Physical exam
Blood tests
Scans
Leukapheresis at the first visit
详细描述
Background:
- Therapeutic vaccination against cancer has proven very challenging with little clinical benefit.
- Vaccines against non-viral tumors have mainly targeted differentiation antigens, cancer testis antigens, and overexpressed antigens. However, negative selection in the thymus against these normal non-mutated antigens severely limits the ability to generate high avidity anti-cancer T-cells. Such depletion can impair their antitumor activity and limit tumor elimination.
- The National Cancer Institute Surgery Branch (NCI-SB) has developed a pipeline for the identification of immunogenic T-cell epitopes derived from neoantigens.
- In recent studies, we identified the neoantigens recognized by tumor-infiltrating lymphocytes (TIL) that mediated regression in patients with metastatic melanoma. Using whole exome sequencing of a resected metastatic nodule followed by high throughput immunologic screening, we were able to demonstrate that tumor regressions were associated with the recognition by the administered TIL of unique somatic mutations that occurred in the cancer.
- We also found that TIL from 29 of 32 patients with a wide variety of metastatic gastrointestinal cancers contained lymphocytes that recognized unique mutations presented in that patient's cancer.
- We, therefore, aim to use this pipeline to identify immunogenic neoantigens and to predict for neoantigens binding the patient human leukocyte antigen (HLA) molecules from melanoma or epithelial cancer patients and to use these epitopes for a personalized therapeutic messenger ribonucleic acid (mRNA) vaccine.

入选标准
- •INCLUSION CRITERIA:
- •Measurable (per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 criteria), metastatic melanoma, gastrointestinal, or genitourinary cancer with at least one lesion that is resectable. Only patients with metastatic gastrointestinal cancer will be eligible for enrollment on the Phase I portion of the study. Patients with metastatic melanoma, gastrointestinal, or genitourinary cancer will be eligible for enrollment on the Phase II portion of the study.
- •Confirmation of diagnosis of metastatic cancer by the National Cancer Institute (NCI) Laboratory of Pathology.
- •Patients with 3 or fewer brain metastases that are less than 1 cm in diameter and asymptomatic are eligible. Lesions that have been treated with stereotactic radiosurgery must be clinically stable for one month after treatment for the patient to be eligible. Patients with surgically resected brain metastases are eligible.
- •Prior therapy with at least one first-line standard of care treatment or second-line treatment of proven effectiveness. Patients must have progressive disease after prior treatment. Prior first-or second-line treatments would include the following:
- •Patients with metastatic melanoma: Receipt of a checkpoint inhibitor as first-line therapy
- •Patients with metastatic melanoma with an activating mutation of KIT: Receipt of Imatinib
- •Patients with a BRAF V600 activating mutation: Receipt of appropriate targeted therapy
- •Patients with metastatic gastrointestinal cancer: Receipt of up to two forms of approved first- and/or second-line chemotherapy regimens
- •Patients with metastatic genitourinary cancers: Receipt of a first- or second-line therapy appropriate for their histologic subtype
- •Age greater than or equal to 18 years and less than or equal to 70 years.
- •Clinical performance status of Eastern Cooperative Oncology Group (ECOG) 0 or
- •Seronegative for human immunodeficiency virus (HIV) antibody. (The experimental treatment being evaluated in this protocol depends on an intact immune system. Patients who are HIV seropositive may have decreased immune-competence and thus may be less responsive to the experimental treatment and more susceptible to its toxicities.)
- •Seronegative for hepatitis B antigen, and seronegative for hepatitis C antibody. If hepatitis C antibody test is positive, then the patient must be tested for the presence of antigen by reverse transcription polymerase chain reaction (RT-PCR) and be hepatitis C virus (HCV) ribonucleic acid (RNA) negative.
- •Hematology
- •Absolute neutrophil count (ANC) > 1000/mm(3) without the support of growth factors.
- •White blood cell (WBC) greater than or equal to 3000/mm(3)
- •Platelet count greater than or equal to 100.000/mm(3)
- •Hemoglobin > 8.0 g/dl. Subjects may be transfused to reach this cut-off.
- •Chemistry
- •Serum Alanine aminotransferase (ALT)/Aspartate aminotransferase (AST) less than or equal to 5.0 times upper limit of normal (ULN)
- •Serum creatinine <1.5 times ULN or measured creatinine clearance (calculated using Cockcroft-Gault formula) > 40 ml/min
- •Total bilirubin less than or equal to 2.0 mg/dl, except in patients with Gilbert's Syndrome, who must have a total bilirubin < 3.0 mg/dl.

结局指标
主要结局
Number of Participants Who Had a Clinical Response (Complete Response + Partial Response) to Treatment (Objective Tumor Regression)
时间窗: up to 12 months
Clinical response was assessed by the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. Complete Response (CR) is disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \< 10 mm. Partial Response (PR) is at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum of diameters. Stable Disease (SD) is neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum of diameters while on study. Progressive Disease (PD) is at least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions is also considered progression.
