Filter by:This is a single arm, open phase II study to evaluate the efficacy and safety of tislelizumab combined with cetuximab + irinotecan in the treatment of Ras wild-type recurrent and refractory colorectal cancer. This study will include Ras wild-type colorectal cancer that failed at least second-line treatment in the past, including chemotherapy (oxaliplatin, irinotecan, fluorouracil) with or without targeted drugs (cetuximab, bevacizumab). 33 patients were planned to be treated with tislelizumab combined with cetuximab + irinotecan every 2 weeks. The enrollment time is expected to be 12 months and the follow-up is 24 months.
The primary objective of the Phase 2 portion of the study is to characterize the clinical activity of maintenance therapy with GRT-C901/GRT-R902 (patient-specific vaccines) in combination with checkpoint inhibitors in addition to fluoropyrimidine/bevacizumab versus a fluoropyrimidine/bevacizumab alone as assessed by molecular response which is based on changes in circulating tumor (ct)DNA. The primary objective of the Phase 3 portion is to demonstrate clinical efficacy of the regimen as assessed by progression-free survival.
In this study, the efficacy of pembrolizumab in patients with locally advanced, irresectable dMMR colorectal cancer will be assessed.
The purpose of this study was to assess efficacy, safety and PK in metastatic colorectal cancer (mCRC) given HLX208 (BRAF V600E inhibitor).
This study will evaluate the safety, and tolerability of neo-adjuvant treatment with tislelizumab in participants with early-stage (Stage II-III) Microsatellite Instability-High (MSI-H) or Mismatch Repair Deficient (dMMR) colorectal cancer.
The Phase 1b part of this study is conducted to assess the safety and tolerability of E7386 in combination with pembrolizumab in participants with previously treated selected solid tumors, and to determine the recommended Phase 2 dose (RP2D) of E7386 in combination with pembrolizumab. The Phase 2 part of this study is conducted to assess the objective response rate (ORR) of E7386 in combination with pembrolizumab (melanoma, colorectal cancer [CRC], hepatocellular carcinoma [HCC]) or of E7386 in combination with pembrolizumab plus lenvatinib (HCC) according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1.
This study is an open-label, multi-center, dose-escalation, dose expansion study in adult subjects with advanced solid tumors. The study will evaluate the safety, tolerability, PK, and preliminary anti-tumor efficacy of SM08502 administered orally (PO), once daily (QD), following a 5 days on 2 days off treatment schedule in combination with chemotherapy or hormonal therapy. Alternative dosing schedules may be explored in Part 1 if necessary. The recommended Part 2 dose and schedule for each combination will then be further evaluated in the Part 2 expansion. Dosing will occur in 21- or 28-day cycles (depending on the combination partner) and treatment with SM08502 will continue within each subject unless treatment is discontinued due to toxicity, disease progression, initiation of a new anti-neoplastic therapy, withdrawal of consent, the Sponsor terminates the study, or the subject no longer meets retreatment criteria.
As a good niche for bacterial growth, appendix plays a very important role in maintaining and protecting intestinal symbiotic flora. Appendectomy will lead to intestinal microecological disorders. Therefore, we put forward the hypothesis that "appendectomy leads to intestinal microecological disorders and then increases the risk of colorectal cancer". In this study, the feces of normal controls, appendectomy and patients with colorectal cancer were collected, and the specific changes of intestinal flora after appendectomy were explored in detail from the level of family, genus and species by macrogenomic sequencing. Then through functional gene analysis, metabolic pathway analysis and other methods to explore the molecular mechanism of colorectal cancer risk changes and the changes of microflora involved, and verified by mouse fecal bacteria transplantation animal experiment.
The purpose of this study is to provide educational materials and information regarding colorectal cancer (CRC), CRC screenings, and United States Preventive Services Task Force's (USPSTF) screening recommendations. USPSTF recommends screening for colorectal cancer starting at age 45 years and continuing until age 75 years.
The purpose of this study is to assess the safety and efficacy of coformulated favezelimab/pembrolizumab (MK-4280A) in participants with metastatic colorectal cancer. The study will also compare MK-4280A with the standard of care treatment of regorafenib and TAS-102 (trifluridine and tipiracil). The primary study hypothesis is that coformulated favezelimab/pembrolizumab (MK-4280A) is superior to standard of care with respect to overall survival.
