AMP-224, a PD-1 Inhibitor, With Stereotactic Body Radiation Therapy in Metastatic Colorectal Cancer

ABSTRACT: Background: - T-cells are white blood cells that can find and kill germs and tumors. Cancer can keep T-cells from working. Researchers think a new drug called AMP-224 might help the T-cells in people with cancer. They think the drug might work even better when combined with a certain type of radiation therapy. Objective: - To study the safety and effectiveness of AMP-224 together with 1 or 3 days of stereotactic body radiation therapy (SBRT) directed to the liver. Eligibility: - People age 18 and older with metastatic colorectal cancer. Their cancer must have spread to the liver and not be responding to treatment. Design: * Participants will be screened with a medical history, physical exam, and blood and urine tests. Their tumors will be measured with computerized tomography (CT) scans or magnetic resonance imaging (MRI) of the chest, stomach, and pelvis. They will have an electrocardiogram (ECG) heart test. * Participants will have a small part of their tumor removed by needle (biopsy). * Participants will have 8 study visits over about 10 weeks. * At 1 visit, they will have another tumor biopsy. * At 1 visit, they will get a chemotherapy drug through a vein (intravenous (IV)). * At 6 visits, they will receive AMP-224 through an IV. * At 1 or 3 visits, they will have SBRT. Computed tomography (CT) scans will map the position of their tumor. Radiation beams of different intensities at different angles will be directed to the tumor. * At all visits, some screening procedures may be repeated. * After treatment ends, participants will have 7 follow-up visits over about 5 months. Blood will be drawn. Some screening procedures may be repeated.

Cellular Damage in the Target and Out-of-Field Peripheral Organs during VMAT SBRT Prostate Radiotherapy: An In Vitro Phantom-Based Study

Project description:New developments show that patients with prostate cancer can benefit from radiotherapy deliv-ered with a hypo-fractionated regimen. The aim of our study was to investigate the effect of hy-po-fractionated stereotactic body radiation therapy (SBRT) of prostate cancer on out-of-field organs. We used a humanoid phantom to irradiate prostate cells in conditions similar to patient therapy, using SBRT planning. Our results show that radiation doses in the location of the intes-tine and lung resulted in significantly higher radiation doses than the further locations. We observed a high radiotoxic effect in the cells irradiated in the prostate, and a small increase in DNA damage and cell killing in the intestine location. Gene expression analysis revealed significant enrichment of the biological processes related to the radiation response in the prostate. In the lung and thyroid, the enrichment of several gene groups was revealed, however the processes were not clearly related to the response to radiation. Our study provides extensive data on out-of-field safety of prostate SBRT.

M9241 in Combination With Hepatic Artery Infusion Pump (HAIP) and Systemic Therapy for Subjects With Metastatic Colorectal Cancer or Intrahepatic Cholangiocarcinoma

Project description:Background: One way to treat liver cancer is to deliver chemotherapy drugs only to the liver (and not to the whole body). Researchers want to see if adding the drug M9241 can improve the treatment. The drug triggers the immune system to fight cancer.<TAB> Objective: To see if treatment with HAIPs to deliver liver-directed chemotherapy in combination with M9241 is effective for certain cancers. Eligibility: People aged 18 and older who have cancer of the bile ducts that is only in the liver, or colorectal cancer that has spread to the liver. Design: Participants will be screened with: Medical history Physical exam Blood tests Pregnancy test (if needed) Tumor biopsy (if needed) Electrocardiogram Computed tomography (CT) scans Participants will have an abdominal operation. A catheter will be placed into an artery that feeds blood to the liver. The catheter will then be attached to the HAIP. The HAIP will lay under the skin on the left side of the abdomen. Participants will have chemotherapy drugs or heparin with saline infused into the HAIP every 2 weeks. M9241 will be injected under the skin every 4 weeks. They will get systemic chemotherapy through an IV or mediport every 2 weeks. They will receive this treatment until their cancer gets worse or they have bad side effects. Participants will have 2 study visits each month. They will have CT scans every 8 weeks. At visits, they will repeat some screening tests. Participants will have a follow-up visit 1 month after treatment ends. Then they will be contacted every 6 months for 5 years.

Platelet mRNA in response to antiplatelet therapy exposure

Project description:The purpose of this study was to identify changes in platelet mRNA that result from exposure to antiplatelet therapy. A total of 84 healthy volunteers were recruited into a longitudinal study of various antiplatelet exposures with 58 completing all study visits. This was a 5 visit study where each visit was separated by ~ 4 weeks. At each Visit purified platelets using a CD45 negative selection protocol was performed in addition to platelet function testing using light transmittance aggregometry (ADP, EPI, and Collagen) and PFA100 (Col/EPI). After the baseline visit (V1), participants were randomized to receive 81mg/day or 325mg/day aspirin x 4 weeks followed by Visit 2. Participants then crossed over to the alternative dose of aspirin for 4 weeks followed by Visit 3. Between Visits 3 and 4 participants washed out their aspirin for 4 weeks. The final exposure was ticagrelor 90mg twice daily x 4 weeks until Visit 5.

Peripheral blood transcriptome profiles in adult male Japanese IT workers.

Project description:Analysis of transcript abundance estimates as a function generalized purpose in life and work-related dimensions of meaning. Gene expression profiling was conducted on peripheral blood samples collected from adult male employees of a Japanese technology firm. In addition to health-relevant background characteristics (age, indcome, body mass index/BMI, smoking history, heavy alcohol consumption history), participants were also assessed for hedonic and eudaimonic dimensions of generalized well-being (assesed by the Short Flourishing Scale, Keyes, C (2006). The Mental Health Continuum-Short Form (MHC-SF) for adults) and work-specific variables including job evaluation (assessed by a12-item scale tapping both perceived significance of the firmâs work, through items such as âI am proud of my companyâ and âI think my company is really good,â as well as perceived significance of oneâs own contribution to the firm's work, through items such as, âI think other employees within my company respect my workâ), and workplace interdependence and independence of the self and coworkers (using the Singelis Self-Construal Scale, Singelis, T. M. (1994). The Measurement of Independent and Interdependent Self-Construals. Personality and Social Psychology Bulletin, 20(5), 580â591). Higher values of each scale score indicate greater levels of well-being, job satisfaction, etc. Dichotomous variables were coded 0=no/absent and 1=yes/present. Valid gene expression data are available for 106 participants.

Modulation of the human pancreatic ductal adenocarcinoma immune microenvironment by stereotactic body radiotherapy

Project description:Purpose: Stereotactic body radiotherapy (SBRT) is an emerging treatment modality for pancreatic ductal adenocarcinoma (PDAC) that can effectively prime cytotoxic T cells by inducing immunogenic tumor cell death in preclinical models. SBRT effects on human PDAC have yet to be thoroughly investigated, therefore, this study aimed to characterize immunomodulation in the human PDAC tumor microenvironment following therapy. Experimental Design: Tumor samples were obtained from patients with resectable PDAC. Radiotherapy was delivered a median of seven days prior to surgical resection, and sections were analyzed by multiplex IHC (mIHC), RNA-Seq, and T cell receptor sequencing (TCR-Seq). Results: Analysis of SBRT-treated tumor tissue indicated reduced tumor cell density and increased immunogenic cell death relative to untreated controls. Radiotherapy promoted collagen deposition, however, vasculature was unaffected and spatial analyses lacked evidence of T cell sequestration. Conversely, SBRT resulted in fewer tertiary lymphoid structures and failed to lessen or reprogram abundant immune suppressor populations. Higher percentages of PD-1+ T cells were observed following SBRT, and a subset of tumors displayed more clonal T cell repertoires. Conclusions: These findings suggest that SBRT augmentation of antitumor immunogenicity may be dampened by an overabundance of refractory immunosuppressive populations, and support the continued development of SBRT/immunotherapy combination for human PDAC.

Towards a mechanistic understanding of response to SBRT by patients with borderline resectable pancreatic cancer

Project description:Five year survival rates for pancreatic cancer remain low, around 11%. We assessed differential gene expression between SBRT responders and non-responders as well as expression pre and post SBRT. Samples were obtained from the University of Colorado biorepository. All patients had borderline resectable pancreatic cancer, treated with neoadjuvant chemotherapy followed by restaging, and treatment with 30–33.6 Gy SBRT to pancreatic tumors, followed by pancreaticoduodenectomy and adjuvant chemotherapy. We observed increases in PDL1, PD1, CD25, and a decrease in CD122 expression following RT. Furthermore, we found that responders to SBRT exhibit decrased CD25 expression with increased CD122 and CD132 expression compared to non-responders. Using GSEA of responders vs. non-responders, we found responders to SBRT exhibit enrichment of inflammatory response, IFN signaling, and IL2/STAT5 signaling.

Study Using Fluorine-18-Labeled Fluoro-Misonidazole Positron Emission Tomography to Detect Hypoxia in Locally Advanced (T3-T4 and./or N1)Primary Rectal Cancer Patients

Project description:When used with a different radioactive tracer called FMISO, a PET scan can find areas of low oxygen in the tumor. We think that having areas of low oxygen is a reason why some tumors are hard to treat with radiation. In a past study, FMISO PET scans were performed in 6 patients with rectal cancer that could not be operated on and that had spread to other areas. In this group of patients, FMISO PET scans were able to find the low oxygen areas in their tumors. But this study included only a few patients. In the present study, we want to use FMISO PET scans in patients who have tumors that can be operated on. This group of patients will have radiation, chemotherapy or both before they have their surgery. We want to see if FMISO PET can find low oxygen areas in this distinct group of patients.
