Filter by:The purpose of this study is to assess the anti-tumor activity of amivantamab as a monotherapy (Cohorts A, B, and C), to characterize the safety of amivantamab when added to standard-of care (SoC) chemotherapy in participants with metastatic colorectal cancer (mCRC) (Ph2 cohorts), and to assess the recommended phase 2 combination dose (RP2CD) of amivantamab when added to SoC chemotherapy (Ph1b cohorts).
This is a single-center, open-label, cohort clinical study to investigate the efficacy and safety of surufatinib with or without immunotherapy in patients with advanced colorectal cancer who failed front-line anti-angiogenic TKI therapy. Patients have to received at least a second-line standard therapy or cannot tolerate other treatments, and have previously failed anti-angiogenic TKIs therapy(including but not limited to: fruquintinib/regorafenib/anlotinib) / apatinib, and are resistant to treatment, disease progression, intolerable toxicity or no continued benefit as assessed by investigator after therapy). Patients who met the eligibility criteria are randomized 1:2 into two cohorts (cohort 1: surufatinib, cohort 2: surufatinib plus immunotherapy) to receive treatment until disease progression, death, unacceptable toxicity, withdrawal of consent by the patient, or decision by the treating physician that discontinuation would be in the patient's best interest. The primary study endpoint was PFS(progression free survival).
Colorectal cancer (CRC) is one of the most common malignant tumours of human beings. Mismatch Repair-deficient (dMMR)/ Microsatellite Instability-high (MSI-H) CRC is a specific subtype of CRC, which accounts for approximately 15% of all CRC patients, and can not benefit from 5-fluorouracil (5-FU) adjuvant chemotherapy. Once patients have distant metastases, they are not sensitive to traditional palliative chemotherapy, and thus lead to much worse prognosis than that of mismatch repair-proficient (pMMR)/ microsatellite stability (MSS). A phase II clinical study of anti-PD-1 immunotherapy based on mismatch repair (MMR) status published in "N Engl J Med" showed that the objective response rate (ORR) of advanced colorectal cancer patients with dMMR received anti-PD-1 is 40%, and a longer response time can be obtained compared to conventional chemotherapy. Another study (ClinicalTrials.gov, NCT03926338) which investigating the effect of neoadjuvant PD-1 blockade with toripalimab, with or without celecoxib, on mismatch repair-deficient or microsatellite instability-high, locally advanced, colorectal cancer. The result revealed that all 34 patients had an R0 resection. 15 of 17 patients (88%) in the toripalimab plus celecoxib group and 11 of 17 patients (65%) in the toripalimab monotherapy group had a pathological complete response. In theory, anti-PD-L1 drugs should have fewer immune side-effects than anti-PD-1 drugs. However, there are no reports of anti-PD-L1 neoadjuvant therapy for the dMMR/MSI-H colorectal cancer. Therefore, the aim of this study was to investigate the efficacy and safety of anti-PD-L1 monoclonal antibody (Envafolimab) as neoadjuvant immuntherapy for resectable local advanced colorectal cancer patient with the dMMR/MSI-H.
The purpose of this clinical research is to establish a multi-omics model based on genomics，transcriptomics，gut microbiota in predicting pathologic response after neoadjuvant chemoradiotherapy combined PD-1 antibody given to patients with locally advanced rectal cancer.
With increasing age and the additional impact from the bowel cancer and the chemotherapy and/ or radiotherapy it has been described that testosterone (a male hormone produced naturally in the body) levels are reduced. Testosterone has an impact on numerous body functions including the muscle mass and quality. Previous studies have identified that muscle mass is reduced as a result of ageing but also because of the deleterious effect of cancer and chemotherapy and/or radiotherapy. There is growing evidence from published studies that patients with better muscle mass and quality, do better after surgery. Mr Jenkins and his team are therefore looking at ways, the investigators can try and prevent or reduce this muscle loss and therefore improve patient outcomes. The aim of this study is to assess whether using testosterone replacement therapy in the form of a topically applied gel daily for a total of 12 weeks, is feasible and acceptable by the patients who are diagnosed with colorectal cancer and are waiting to undergo surgery. The investigators will also collect information related to the testosterone replacement therapy such as questionnaires on the quality of life, fatigue and muscle mass, and blood biomarker changes in the blood.
The increase in the survival of cancer patients and the incidence of cancers leads to a rapid increase in the number of people living after a diagnosis of cancer. Occupation during chemotherapy treatment time has been identified as an excellent way to support cancer patients. Studies show that distraction interventions increase tolerance to treatment, by decreasing the importance given to negative stimuli associated with chemotherapy and increasing pleasurable emotions. In this context, virtual reality (VR) is a promising intervention for patients receiving chemotherapy. VR is considered a powerful painkiller, even more effective than other distractors, such as movies or video games for example. Several studies have shown short-term beneficial effects of integrating VR in patients undergoing chemotherapy. This intervention would help patients better adhere to and tolerate treatment. Considering that positive emotions could be one of the underlying processes necessary for the effectiveness of VR, it would be possible to support the cancer patient towards better overall well-being thanks to these new technologies. Investigators can therefore ask themselves the question of the impact that VR used during chemotherapy can have on the adaptation of patients to the disease and its treatments as well as on their psychological distress in the medium and long term.
A multicenter,open,prospective randomized controlled trial;11 study center in China; Plan to enroll 328 patients（ Power Analysis and Sample Size ）.Comparing FOLFIRI with mFOLFOX6,Superiority design.Investigate difference PFS,ORR,R0 resection rate,OS ,QoL and Safety from two regimens Stratification factors : Analyzing patients recurrence within 6-12months,and 12-18months .Obtain definite chemotherapy regimen shift opportunity for patients recurrence/metastasis after adjuvant chemotherapy.
This multi-center study will compare multi-target DNA and quantitative FIT stool-based testing to colonoscopy in individuals with Cystic Fibrosis (CF) undergoing colon cancer screening with colonoscopy. The primary endpoint is detection of any adenomas, including advanced adenomas and colorectal cancer (CRC).
Surgery with integrated treatment for metastatic colorectal cancer (mCRC) has created a new clinical setting known as mCRC with no evidence of disease (NED). However, these patients have a high risk of developing persistent cancer. This study aimed to investigate the efficacy and safety of Tislelizumab combined with capecitabine as a maintenance treatment for patients with mCRC-NED.
This is Phase Ib/II, multicenter, open-label adaptive platform study of JDQ443 with select therapies in patients with advanced solid tumors harboring the KRAS G12C mutation.
