Filter by:The primary goal of this study is to estimate the effectiveness of a medical decision support system based on artificial intelligence in the endoscopic diagnosis of benign tumors. Researchers will compare Adenoma detection rate between "artificial intelligence - assisted colonoscopy" and "conventional colonoscopy" groups to evaluate the clinical effectiveness of artificial intelligence model.
This clinical trial is studying advanced solid tumors. Solid tumors are cancers that start in a part of your body like your lungs or liver instead of your blood. Once tumors have grown bigger in one place but haven't spread, they're called locally advanced. If your cancer has spread to other parts of your body, it's called metastatic. When a cancer has gotten so big it can't easily be removed or has spread to other parts of the body, it is called unresectable. These types of cancer are harder to treat. Patients in this study must have cancer that has come back or did not get better with treatment. Patients must have a solid tumor cancer that can't be treated with standard of care drugs. This clinical trial uses an experimental drug called SGN-MesoC2. SGN-MesoC2 is a type of antibody-drug conjugate (ADC). ADCs are designed to stick to cancer cells and kill them. They may also stick to some normal cells. This study will have 3 parts. Part A and Part B of the study will find out how much SGN-MesoC2 should be given to participants. Part C will use the information from Parts A and B to see if SGN-MesoC2 is safe and if it works to treat solid tumor cancers.
Colorectal cancer (CRC) is the third most common type of cancer diagnosed worldwide and in China. The purpose of this study is to assess adverse events and how ABBV-400 moves through the body of adult participants with unresectable locally advanced/metastatic CRC. ABBV-400 is an investigational drug being developed for the treatment of CRC. Study doctors put the participants in cohorts called treatment arms. Each treatment arm receives a different dose of ABBV-400. This study will include a dose escalation phase to determine the best dose of ABBV-400, followed by a dose expansion phase to confirm the dose. Up to approximately 27 adult participants with unresectable locally advanced/metastatic CRC, will be enrolled in the study in approximately 10 sites in China. In the dose escalation arms, participants will receive escalating doses of intravenously (IV) infused ABBV-400 dose A or B. In dose expansion arm part 1, participants will receive the optimal dose of IV infused ABBV-400. In dose expansion arm part 2, participants will receive the dose B of IV infused ABBV-400. The total study duration will be approximately 2.5 years. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at an approved institution (hospital or clinic). The effect of the treatment will be frequently checked by medical assessments, blood tests, questionnaires and side effects.
The goal of this clinical trial is to evaluate single-fraction metastases-directed SBRT in the broader radiation oncology community and to compare its safety and efficacy profile with the current Standard of Care (SoC) of multiple-fraction SBRT in patients with oligometastatic disease of primary breast, prostate, NSCLC and colorectal cancer having all lesions that will be treated with radical radiotherapy amenable to single-fraction SBRT. The main question/hypothesis this clinical trial aims to answer is: - Single-fraction SBRT has comparable outcomes as those obtained with multiple fraction SBRT, both in terms of safety and efficacy. Patients from the OligoCare cohort will be randomized to receive either single-fraction SBRT or the current SoC of multiple-fraction SBRT.
Phase 1 study to evaluate safety, tolerability and anti-tumor activity of RGT-61159 in patients with ACC or CRCT
The aim of this clinical trial is to find out whether Regorafenib and Sintilimab in combination with electroacupuncture works in treating participants with microsatellite stable (MSS) advanced colorectal cancer who have failed one or more second-line standard chemotherapy regimens. It will also learn about the efficacy and safety of the combination therapy. The main questions the trial aims to answer are: Does combination therapy reduce the overall survival time ? What medical problems do people have when they take combination therapy? Participants will Regorafenib, take for 2 weeks and stop for 1 week; Sintilimab, intravenous, every 3 weeks; Electroacupuncture was performed 1 day before, on the day of, and on the 2nd day after each cycle of Sintilimab administration, and patients completed 3 treatments in week 1, followed by 1 treatment per week for 2 weeks, with 5 treatments per dosing
The purpose of this study is to learn about the safety and effects of the study medicine alone or when given together with other anti-cancer therapies. This study also aims to find the best dose. This study is seeking participants who have solid tumors (a mass of abnormal cells that forms a lump or growth in the body) that: - are advanced (cancer that doesn't disappear or stay away with treatment) and - have a KRAS gene mutation (a change in the DNA of the KRAS gene that can cause cells to grow in very high numbers). This includes (but limited to) the following cancer types: Non-Small Cell Lung Cancer (NSCLC): It's a type of lung cancer where the cells grow slowly but often spread to other parts of the body. Colorectal Cancer (CRC): This is a disease where cells in the colon (a part of large intestine) or rectum grow out of control. Pancreatic ductal adenocarcinoma (PDAC): This is a cancer that starts in the ducts of the pancreas but can spread quickly to other parts of the body. Pancreas is a long, flat gland that lies in the abdomen behind the stomach. Pancreas creates enzymes that help with digestion. It also makes hormones that can help control your blood sugar levels. All participants in this study will take the study medication (PF-07934040) as pill by mouth twice a day repeating for 21-day or 28-day cycles. Depending on which part of the study participants are enrolled into they will receive the study medication (PF-07934040 alone or in combination with other anti-cancer medications). These anti-cancer medications will be given in the study clinic by intravenous (IV) that is directly injected into the veins at various times (depending on the treatment) during the 21-day or 28-day cycle. Participants can continue to take the study medication (PF-07329640) and the combination anti-cancer therapy until their cancer is no longer responding. The study will look at the experiences of people receiving the study medicines. This will help see if the study medicines are safe and effective. Participants will be involved in this study for up to 4 years. During this time, they will come into the clinic between 1 to 4 times in each 21-day or 28-day cycle. After they have stopped taking the study medication (at about at 2 years) they will be followed for another two years to see how they are doing.
Background : In unresectable mCRC, a de-escalation strategy using maintenance or chemotherapy (CT) discontinuation in selected cases is considered as a valid option in non-progressive patients after a first-line induction of doublet CT + targeted agent (TA) (1-7). In this context, circulating tumor DNA (ctDNA) is considered very promising to optimize decision making. Indeed, ctDNA harbour the same main alterations of the tumor and has been recognized as biologically relevant to reflect tumor dynamics and therapeutic efficacy (8). As we and other groups reported in mCRC, that early variation of ctDNA during CT may be relevant to predict outcome (9-11). Indeed, patients with a ctDNA decrease from the first (C1) to the third (C3) cycles of CT (∆≥80% or ctDNA<0.1 ng/ml at C3) or without ctDNA detectable at C1 and C3 have significant better survival as compared to patients with less decrease or with ctDNA increase (10). ctDNA monitoring had never been prospectively evaluated to guide early adaptation in the treatment strategy in mCRC. Aim: A randomized phase III, open label, strategy trial of the superiority in overall survival (OS) adjusted on quality of life of an early treatment adaptation guided by ctDNA variation versus a standard management in unresectable left-side, MSS-BRAFV600E non-mutated mCRC treated by first-line doublet CT + TA. Patients and methods : -Main inclusion criteria will be (i) unresectable left-side and non-pre-treated mCRC (ii) MSS and non-mutated BRAFV600E tumor (iii) at least one measurable lesion (iv) ECOG 0-1 and adequate biological functions for first-line doublet CT + TA (antiEGFR if RAS WT, bevacizumab (BV) if RAS MUT). Randomization (1:1) between an experimental strategy guided by ctDNA variation with de-escalation (Arm A1 or A2) or switch of treatment (Arm A3) versus standard strategy (Arm B). The analysis of variation of ctDNA from C1-C3 will be centralized and detected using Digital PCR targeting hypermethylation of WIF1/NPY genes (10) in real-time in arm A and in second step in arm B. Randomization in Arm A: after 4 cycles of doublet + TA, non-progressive patients will be allocated to a strategy according to ctDNA value and variation from C1-C3: Arm A1: CT discontinuation (ctDNA normalization < 0.1 ng/ml or ctDNA not detectable) Arm A2 : maintenance with fluoropyrimidine + TA (ctDNA ≥ 0.1 ng/ml and ∆ctDNA≥ 80%). Arm A3 : ctDNA non-responders (∆ctDNA < 80% or increase) : switch of CT +/- TA. Randomisation in Arm B: at least 8 cycles of doublet CT + TA before adaptation of sequence at physician choice. Statistical considerations : with an expected median OS at 32 months (mean 37.6 months), a mean QoL at 70.0% in first-line mCRC, corresponding to 0.700 x 37.6 = 26.3 QALM or 2.19 QALY (SD 1.18 QALY), 408 patients are required (randomization 1:1) to show a gain of 4 months of quality-adjusted OS (4 QALM or 0.33 QALY) in experimental ctDNA strategy versus standard strategy (5% two-sided type I error rate, 81% power and 1.18 QALY SD). The secondary objectives will be: - To compare strategies (standard vs ctDNA guided) overall and in the subgroups of ctDNA response on 18, 24 and 36-months restricted mean of QoL-adjusted OS, OS, PFS, response rate, toxicity, Quality of Life and cost utility. - Bio-collection for further ctDNA analysis. Only cost of samples collection and their transportation to the resource center is requested. Further ancillary analysis will be subject to independent funding requests to evaluate : - ctDNA kinetics during the induction and its impact on outcome in overall population and in each arm - ctDNA changes between time points during de-escalation arms to determine thresholds of variations predictive of clinical and/or radiological progression. Conclusion: DIAMOND is a randomized phase III strategy trial to show the superiority in OS adjusted on quality of life of an early treatment adaptation guided by ctDNA versus a standard management in unresectable left-side, MSS-BRAFV600E non-mutated mCRC treated by first-line doublet CT + TA.
There are significant barriers to colorectal cancer screening within underserved populations due to the cost, accessibility, and acceptability of screening methods. Patient-friendly approaches that minimize stress and discomfort for the patient are needed to enhance screening compliance and achieve an early diagnosis. The primary aim of this study is to examine whether the availability of a blood-based screening option, which can be done at the point of service and is familiar to patients, will improve patient compliance to recommended CRC screening
This study assesses the effectiveness of colorectal cancer (CRC) screening intervention, mobile Patient Technology for Health (mPATH™-Cloud), compared to usual care among subjects who are overdue for CRC screening according to recommendations of the United States Preventive Services Taskforce (USPSTF). The trial randomly selects and enrolls 1,000 eligible subjects served by one federally qualified health center (FQHC) in North Carolina. Subjects are randomized to two study arms, Usual Care (Arm 1) or Mobile Health Decision Support (Arm 2). Usual care consists of a visit-based screening recommendation to complete a stool test (e.g., FOBT, FIT, Cologuard) or referral to a screening colonoscopy. Subjects randomized to the Mobile Health Decision Support (Arm 2) are sent a message by text or US mail, depending on their preferred communication mode as indicated in the electronic health record (EHR), to visit the mPATH™-Cloud website. Subjects who engage with mPATH™-Cloud are invited to answer brief questions to confirm their eligibility and then view a short decision aid video designed to help people choose the CRC screening test (FIT or colonoscopy) that they would like to receive. After watching the video, subjects can choose a CRC screening test. Their primary care provider at the FQHC orders the appropriate test and, where indicated, refers the subjects to a colonoscopy. Subjects who request FIT screening and subjects who do not select any test receive a FIT mailed to their home address. The primary outcome of interest is CRC screening completion within 6 months after randomization as assessed by EHR chart review. A completed screening is any of the following: colonoscopy completion (regardless of indication); 2) at least one FIT test with a normal result; or diagnostic colonoscopy following an abnormal FIT result. We hypothesize that we will observe a higher CRC screening completion rate in the Mobile Health Decision Support intervention arm (Arm 2). This study includes up to three annual rounds of screening eligibility assessment and outreach. Repeated intervention rounds allow us to evaluate whether the intervention can improve adherence to USPSTF recommendations over time. During the 3-year intervention phase, Arm 1 receives usual care only.
