Durvalumab and Tremelimumab in Treating Patients With Microsatellite Stable Metastatic Colorectal Cancer to the Liver

ABSTRACT: This pilot clinical trial studies the side effects and how well durvalumab and tremelimumab work in treating patients with microsatellite stable colorectal cancer that has spread to the liver. Monoclonal antibodies, such as durvalumab and tremelimumab, may interfere with the ability of tumor cells to grow and spread.

Study of Durvalumab and Tremelimumab After Radiation for Microsatellite Stable Metastatic Colorectal Cancer Progressing on Chemotherapy

Project description:This study is being done to look at the safety and response to the combination of two investigational drugs, tremelimumab and durvalumab, when given after radiation therapy for patients with microsatellite stable (MSS) metastatic colorectal cancer. Tremelimumab and durvalumab recognize specific proteins on the surface of cancer cells and trigger the immune system to destroy the cancer cells. In order to learn more about certain characteristics of colorectal cancer tumors, this study includes special research tests using samples from diagnostic tumors, fresh tumor samples from an area where the cancer has spread, and blood samples.

First-line durvalumab and tremelimumab with chemotherapy in RAS-mutated metastatic colorectal cancer: a phase 1b/2 trial [RNA-Seq]

Project description:While patients with microsatellite instable, metastatic colorectal cancer (CRC) benefit from immune checkpoint blockade, chemotherapy with targeted therapies remains the only therapeutic option for microsatellite stable (MSS) tumors. The single arm, phase IB/II MEDITREME trial evaluates safety and efficacy of durvalumab plus tremelimumab in combination with mFOLFOX6 chemotherapy in first line, in 57 patients with RAS-mutant unresectable mCRC. Safety was primary objective of phase IB and no safety issue was observed. The primary objective of phase II was efficacy in terms of 3-month PFS in MSS patients, which was met with a 3 month PFS of 90.7% [95% CI: 79.2-96%]. For secondary objective, response rate was 64.5%, median PFS was 8.2 months [95% CI: 5.9–8.6] and overall survival was not reached in MSS patients. Higher tumor mutational burden and a lower degree of genomic instability in responder patients. Integrated transcriptomic analysis underlined that high immune signature, and low epithelio-mesenchymal transition were associated with better outcome. Immunomonitoring showed induction of neoantigen and NY-ESO1 and TERT blood tumor specific T cell response associated with better PFS. The combination of durvalumab-tremelimumab with mFOLFOX6 was tolerable with promising clinical activity in MSS mCRC.

Durvalumab (MEDI4736) with or without tremelimumab in MSS and MSI colorectal and endometrial tumors

Project description:Primary objectives: To assess the antitumor activity of Durvalumab or Tremelimumab 300 mg single dose followed by Durvalumab in patients with microsatellite instable (MSI) colorectal cancer (CRC) or endometrial cancer (EC) and Tremelimumab 300 mg single dose followed by Durvalumab in refractory microsatellite stable (MSS) CRC and EC as defined by objective response rate (ORR) according to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 Primary endpoints: Objective response rate (ORR) according to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1, and iRECIST if applicable, in patients with advanced, immune naïve MSS CRC, MSS EC, MSI CRC and MSI EC.

Tremelimumab and Durvalumab in Treating Patients With Colorectal Cancer With Liver Metastases That Can Be Removed by Surgery

Project description:This phase I trial studies the side effects and how well tremelimumab and durvalumab work in treating patients with colorectal cancer that has spread to the liver and can be removed by surgery. Immunotherapy with monoclonal antibodies, such as tremelimumab and durvalumab, may help the body’s immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

Durvalumab and Tremelimumab With or Without High or Low-Dose Radiation Therapy in Treating Patients With Metastatic Colorectal or Non-small Cell Lung Cancer

Project description:This randomized phase II trial studies the side effects of durvalumab and tremelimumab and to see how well they work with or without high or low-dose radiation therapy in treating patients with colorectal or non-small cell lung cancer that has spread to other parts of the body (metastatic). Immunotherapy with durvalumab and tremelimumab, may induce changes in body’s immune system and may interfere with the ability of tumor cells to grow and spread. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving durvalumab and tremelimumab with radiation therapy may work better in treating patients with colorectal or non-small cell lung cancer.

Effects of durvalumab alone or combined with tremelimumab on preexisting cells in the tumor microenvironment

Project description:Immune checkpoint blockade with anti–PD-1/L1 or anti–CTLA-4 therapies has shown promising results across multiple cancer types, but the mechanisms within the tumor microenvironment (TME) have not been fully characterized. We used single-cell RNA sequencing to investigate the effects of anti–PD-L1 monoclonal antibody (mAb) durvalumab (D) alone and combined with an anti–CTLA-4 mAb, tremelimumab (T), on distinct subsets of immune cells. Upon treatment with D or D+T, two NSCLC tumors showed elevated IFNγ responses, although they differed in magnitude of response but differed in other areas. Our results highlight that D and D+T in the TME have some consistent effects across tumors but also exhibit tumor-specific effects depending on composition and functional state of immune cells in the TME at time of treatment. This complex tumor-specific interplay of diverse immune subtypes in the TME is critical to better understand patient response to immunotherapy.

Microsatellite stable (n=38) and instable-high (n=13) human colorectal tumors assayed with Affymetrix HuGeneFL arrays.

Project description:mRNA assays were performed on 51 samples of human colorectal tumors using Affymetrix HuGeneFL arrays containing 7129 probe-sets. We compared 38 microsatelite stable (MSS) tumors with 13 microsatellite instable-high (MSI) tumors to form a list of genes differing between the two types. In order to identify molecular signatures characterizing MSI tumors, we examined only MSI-high cancers and not MSI-low ones. Keywords: disease state analysis Human samples of 38 microsatellie stable and 13 microsatellite instable-high colorectal tumors, each from a separate patient, had mRNA assays performed using Affymetrix HuGeneFL arrays, with 7129 probe-sets. A supplementary Excel file (Colon_HuFL_logs.xls) is attached below that gives the log-transformed probe-set values. It also gives the p-values from T-tests comparing these values between MSS and MSI samples, as well as an estimated average fold-difference, for which the mathematical functions are explicitly given.
