Filter by:This is a Phase Ib study to evaluate the safety and preliminary anti-tumor activity of pembrolizumab in combination with pemetrexed with or without oxaliplatin in patients with chemo-refractory microsatellite stable (MSS) metastatic colorectal cancer (mCRC) without any further standard treatment options.
The Adventist Health Study-2 is a long-term study, exploring the links between lifestyle, diet, and disease outcomes among Seventh-day Adventists. More than 96,000 church members from the U.S. and Canada are participating in the current study, AHS-2, conducted by researchers at the Loma Linda University School of Public Health.
This phase II trial studies how well autologous tumor infiltrating lymphocytes MDA-TIL works in treating patients with ovarian cancer, colorectal cancer, or pancreatic ductal adenocarcinoma that has come back (recurrent) or does not respond to treatment (refractory). Autologous tumor infiltrating lymphocytes MDA-TIL, made by collecting and growing specialized white blood cells (called T-cells) from a patient's tumor, may help to stimulate the immune system in different ways to stop tumor cells from growing.
This phase II trial studies how well chemotherapy and/or metastasectomy work in treating patients with colorectal adenocarcinoma that has spread to the lungs (metastases). Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Metastasectomy is a surgical procedure that removes tumors formed from cells that have spread from other places in the body. It is not yet known if chemotherapy and metastasectomy together works better in treating patients with metastatic colorectal adenocarcinoma with lung metastases.
Acute colon cancer surgery has a poor 90-day mortality of 21.0% compared with only 3% after elective colorectal cancer surgery in Denmark. The high mortality after acute colon cancer surgery compared with elective surgery emphasizes the importance of identifying factors associated with acute onset and poor short-term survival after acute surgery. Socioeconomic position has previously showed to be a risk factor for acute versus elective onset of colorectal cancer. Furthermore, if patients with low socioeconomic position have higher postoperative mortality this could reflect differences in the treatment of patients according to their socioeconomic position. The aim of the clinical study is: 1. To examine if patients with short education, low income, living alone, or living in rural areas are more likely to undergo acute colorectal cancer surgery than elective surgery compared with patients with longer educations, higher income, living with a partner, or living in urban areas. 2. To examine if there is an association between education, income, cohabitation, or urbanicity and 1-year mortality after acute colorectal cancer surgery.
This is a prospective, open-lable, multicenter, randomized, controlled, phase II clinical study. The aim is to evaluate the efficacy of Irinotecan versus Oxaliplatin in the first-line treatment of refractory metastatic colorectal cancer.
QUILT 3.071 NANT Colorectal Cancer (CRC) Vaccine: Phase 1b/2 NANT CRC Vaccine vs Regorafenib in Subjects with CRC Who have Previously Treated with SOC.
This is a multi-center Phase II randomized study. We plan to enroll 78 patients with biopsy-proven hepatic-limited metastatic colorectal cancer deemed resectable after multi-disciplinary discussion. Eligible patients must have confirmed isolated liver metastases by radiographic imaging of the investigators' choosing. Imaging must include the chest, abdomen, and pelvis regardless of imaging modality chosen. Patients will be randomized to either the control arm or the experimental arm. The control arm will receive mFOLFOX6 every 2 weeks for 4 cycles concurrently with Nivolumab. The experimental arm will first be treated with 2 vaccinations of MVA-BN-CV301 given two weeks apart (Days -28, -14) concurrently with Nivolumab followed by 4 vaccinations of FPV-CV301 given two weeks apart concurrently with mFOLFOX6 and Nivolumab, which will again be administered every 2 weeks for 4 cycles (FPV-CV301, mFOLFOX6 and Nivolumab) After Cycle 4, patients will be re-evaluated for surgical resection by re-staging CT chest, abdomen and pelvis (C/A/P). Patients still considered resectable will undergo surgical resection with the goal of complete resection. Patients who cannot be completely resected will continue to be followed on study, and an additional appropriate candidate will be randomized to the corresponding arm. We will collect peripheral blood and tumor tissue at the time of surgical resection, if applicable, or by re-biopsy if resection is not possible. Post-operative therapy will begin when patients are deemed ready by their surgical oncologist team. Patients in the control arm will then undergo another 8 cycles of mFOLFOX6 with Nivolumab administered concurrently. Nivolumab will then be administered every four weeks. The experimental arm will receive the same post-operative regimen but including FPV-CV301 boosters given concurrently with mFOLFOX6 and Nivolumab. FPV-CV301 will then be administered every 12 weeks, and Nivolumab every 4 weeks. We will collect peripheral blood for evaluation of correlates upon the completion of therapy. The vaccination approach of initial immunization during the neoadjuvant period followed by FPV-CV301 boosters for two years postoperatively was chosen to optimize the induction of a long-lasting tumor-specific host response. Neoadjuvant vaccination will also allow for analysis of the tumor microenvironment in resection specimens. Post-therapy patients will be under surveillance per NCCN guidelines with repeat CEA every 3 months for 2 years followed by every 6 months for 1 year (total 3 years), repeat CT of the C/A/P every 3 months for 2 years followed by every 6 months for up to 1 year (total 3 years), and colonoscopy at one year with repetition based on findings at the time of the procedure.
Interventional, prospective, randomized (1:1), controlled, open label, multicenter phase IIb study in patients with advanced metastatic colorectal cancer. The scope of the trial is to evaluate overall survival of either regimen (TAS102 +/- Ramucirumab) and evaluate safety and tolerability.
In this study, MMRd metastatic colorectal cancer (mCRC) patients who failed standard therapies will undergo treatment with pembrolizumab, while RAS-extended mutated MMR-proficient mCRC patients will be tested for o6-methylguanine-DNA-methyltransferase (MGMT) expression (IHC) and then for MGMT promoter methylation. MGMT IHC-negative, promoter methylation positive patients will be treated with temozolomide (TMZ). Patients progressing under temozolomide will be tested for tumor mutational burden (TMB) and proceed to pembrolizumab if TMB is > 20 mutations/Mb. The primary study hypothesis is that tumors with acquired resistance to temozolomide become hypermutated and are sensitive to pembrolizumab.
