転移性がん患者におけるKRAS変異に対して反応性の受容体を発現するように遺伝子操作された自家T細胞と、これらの抗原に対するワクチンを併用
転移性がんの参加者におけるKRAS変異に対して反応性の受容体を発現するように遺伝子操作された自己T細胞と、これらの抗原に対するワクチンの併用投与を評価する第Ib相臨床試験
Background:
Many cancer cells produce substances called antigens that are unique to each cancer. These antigens stimulate the body s immune responses. One approach to treating these cancers is to take disease-fighting white blood cells from a person, change those cells so they will target the specific proteins (called antigens) from the cancer cells, and return them to that person s blood. The use of the white blood cells in this manner is one form of gene therapy. A vaccine may help these modified white cells work better.
Objective:
To test a cancer treatment that uses a person s own modified white blood cells along with a vaccine that targets a specific protein.
Eligibility:
Adults aged 18 to 72 years with certain solid tumors that have spread after treatment.
Design:
Participants will undergo leukapheresis: Blood is removed from the body through a tube attached to a needle inserted into a vein. The blood passes through a machine that separates out the white blood cells. The remaining blood is returned to the body through a second needle.
Participants will stay in the hospital for 3 or 4 weeks. They will take chemotherapy drugs for 1 week to prepare for the treatment. Then their modified white cells will be infused through a needle in the arm. They will take other drugs to prevent infections after the infusion.
The vaccine is injected into a muscle; participants will receive their first dose of the vaccine on the same day as their cell infusion.
Participants will have follow-up visits 4, 8, and 12 weeks after the cell infusions. They will receive 2 or 3 additional doses of the boost vaccine during these visits.
Follow-up will continue for 5 years, but participants will need to stay in touch with the gene therapy team for 15 years.

調査の概要
状態
詳細な説明
Background:
- The majority of cancer deposits from patients with melanoma or solid epithelial cancers contain tumor infiltrating lymphocytes (TIL) that can recognize unique mutated neoantigens expressed by the cancer.
- Administration of autologous TIL to patients with metastatic melanoma can mediate complete durable regression in up to 24% of patients with metastatic melanoma. The administration of TIL from patients with solid epithelial cancers mediate far fewer clinical responses probably because the frequency of these anti-tumor T cells in solid epithelial cancers is very low (often less than 0.1%).
- We have developed approaches to adoptive cell transfer (ACT) therapy that involves isolating T-cell receptors (TCR) that recognize mutated cancer neoantigen. These TCRs are transduced into autologous peripheral lymphocytes to express these TCRs with high efficiency. These neoantigen TCR gene-modified cells can recognize and destroy the autologous cancer in vitro.
- In a single patient with chemo-refractory metastatic colon cancer, we identified a rare population of neoantigen reactive TIL targeting the KRAS G12D hotspot mutation and administration of these TIL mediated a near-complete regression of all metastatic disease now lasting over 5 years. The administration of cells genetically modified to express anti KRAS G12D receptors obtained from this patient have now been used to mediate regression of metastatic pancreatic cancer in a patient containing a G12D mutation. Using targeted screening and in vitro sensitization of PBL and TIL, we have now identified a library of TCRs capable of recognizing the KRAS G12D or KRAS G12V shared mutations restricted by a variety of Class I or Class II MHC restriction elements.
- In murine experiments utilizing T-cell receptors against mutated antigens, we have shown that cells bearing these receptors are far more effective in mediating anti-tumor responses against established tumors when cell administration is combined with a vaccine targeting the same antigen targeted by the T cells.
- Gritstone bio has developed a prime boost adenoviral/mRNA vaccine targeting KRAS G12D and G12V shared mutations.
- The clinical protocol described here will treat participants with chemorefractory solid cancers that express G12D or G12V KRAS mutations using the adoptive transfer of autologous lymphocytes transduced with genes encoding TCRs that recognize these mutations in conjunction with the administration of an anti-KRAS vaccine.
Objectives:
-Primary objective:
--Determine the safety and efficacy of administering autologous T cells transduced to express receptors targeting KRAS G12D or G12V mutations in conjunction with an anti-KRAS vaccine to participants with metastatic solid cancers that contain KRAS G12D or G12V mutations.
Eligibility:
-Participants must be/have:
- Age >= 18 years and <= 72 years
- Metastatic cancer that expresses either the KRAS G12D or KRAS G12V hotspot mutation for which the Surgery Branch has identified TCRs capable of recognizing these antigens with appropriate MHC restriction.
- Evaluable solid cancer that has recurred following standard systemic therapy.
- Adequate basic laboratory values.
- No concurrent major medical illnesses or any form of immunodeficiency.
Design:
- Participants who have cancers demonstrated to contain KRAS G12D or G12V genetic mutations in the autologous cancer will be included.
- T-cell receptors that recognize KRAS G12D or G12V mutations will be inserted into participant PBL and used for cell transfer immunotherapy. Participants will also receive a KRAS prime-boost vaccine that expresses G12D and G12V hotspot mutation epitopes.
- Participants will be enrolled into one of four cohorts: (1) G12D KRAS mutations treated with TCRs recognizing these mutations restricted by Class I MHC molecules, (2) G12D KRAS mutations treated with TCRs recognizing these mutations restricted by Class II MHC molecules, (3) G12V KRAS mutations treated with TCRs recognizing these mutations restricted by Class I MHC molecules, (4) G12V KRAS mutations treated with TCRs recognizing these mutations restricted by Class II MHC molecules.
- Clinical and immunologic responses will be evaluated about 4-6 weeks after cell infusion and periodically thereafter.
- It is anticipated that approximately 3 participants may enroll on the trial each month. There will be an initial limit of 21 evaluable participants per cohort for a total of 84 evaluable participants. Thus, the initial accrual may be completed in approximately 3 years. Any group moving to a second-stage evaluation would accrue an additional 29 evaluable participants over approximately two years for a potential total of 200 evaluable participants.
