The combination of anti-cancer drugs trifluridine and tipiracil is called TAS-102. It prevents cancer cells from growing and multiplying.\n\nBoth regorafenib and TAS-102 are approved treatments for metastatic colorectal cancer and are available for doctors to prescribe to people with mCRC after previous lines of treatment have been unsuccessful.\n\nRegorafenib and TAS-102 work in different ways and impact people differently. People might receive one of these drugs first and followed by the other. The best sequence for taking these drugs is still unclear.\n\nResearchers have also found that TAS-102, when taken with another anti-cancer drug called bevacizumab, helps people live longer than when taken alone.\n\nTo better understand the impact of the sequence of taking regorafenib and TAS-102 (with or without bevacizumab), more knowledge is needed about how these work together in people with mCRC in real world settings.\n\nThe main purpose of this study is to learn more about the characteristics and impact of treatment in people with mCRC who received regorafenib and TAS-102 (with or without bevacizumab) one after the other. This information will be grouped based on their treatment sequence and age group (less or more than 65 years old).\n\nIn addition, the researchers want to learn about :\n\n* how long participants were treated with regorafenib and TAS-102 taken one after the other in a sequential order,\n* any treatment for mCRC that the participants received after the sequential treatment,\n* any treatment received for a condition in which the bone marrow cannot make up enough blood cells (a common side effect of cancer treatment), during the sequential treatment,\n* if and how often white blood cells that fight infection decreased during the sequential treatment,\n* the number of hospital or testing facility visits that participants had during the sequential treatment, and\n* how long did participants live (also called overall survival).\n\nThe participants in this study had already received regorafenib and TS-102 (with or without bevacizumab) as part of their regular care from their doctors.\n\nThe data will come from the participants' information stored in an electronic health records database called Flatiron mCRC EDM. Data collected will be from January 2015 to December 2022.\n\nResearchers will only look at the health information from adults in the United States of America.\n\nIn this study, only available data from routine care is collected. No visits or tests will be required as part of this study."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Patients with mCRC who received sequential treatment of Regorafenib and TAS-102 (with or without Bev), and patients with mCRC who received combo use of TAS+BEV from Jan 2015 to Sep 2022 (or 3 months prior to the latest data cut) from Flatiron CRC EDM data (v Dec 2022 or the latest version)', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Adult patients who had diagnosis of mCRC (≥18 years old at diagnosis of mCRC)\n* Received sequential treatment of regorafenib and TAS-102 (either mono or with bevacizumab) after mCRC diagnosis, with at least one documented clinical visit on or after treatment; OR\n* Patients with mCRC who received combo use of TAS+BEV, with at least one documented clinical visit on or after treatment\n\nExclusion Criteria:\n\n* Patients who had a diagnosis of gastrointestinal stromal tumors (GIST) or hepatocellular carcinoma (HCC) or other primary cancers in the baseline period (i.e., 6 months prior to index date) except non-melanoma skin cancers\n* Patients involved in clinical trials during the study period (as indicated by the masked therapies)'}, 'identificationModule': {'nctId': 'NCT05839951', 'acronym': 'STAR-T', 'briefTitle': 'An Observational Study Called STAR-T to Learn More About the Sequential Treatment With Regorafenib and TAS-102 in Adults With Metastatic Colorectal Cancer Under Real World Conditions', 'organization': {'class': 'INDUSTRY', 'fullName': 'Bayer'}, 'officialTitle': '(STAR-T) Sequential TreAtment With Regorafenib and Trifluridine/Tipiracil (TAS-102, With or Without Bevacizumab) in Refractory Metastatic Colorectal Cancer: Real-world Outcomes in Community Clinical Practice in the USA', 'orgStudyIdInfo': {'id': '22386'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'Cohort R-T', 'description': 'Patients with mCRC who started with regorafenib first, followed by TAS+/-Bev (Bevacizumab) without other therapies in between.', 'interventionNames': ['Drug: Regorafenib (BAY73-4506, Stivarga®)', 'Drug: Bevacizumab']}, {'label': 'Cohort T-R', 'description': 'Patients with mCRC who started with TAS+/-Bev first, followed by regorafenib, without other therapies in between.', 'interventionNames': ['Drug: TAS-102 (trifluridine and tipiracil, Lonsurf®)', 'Drug: Bevacizumab']}, {'label': 'Cohort TAS+BEV', 'description': 'Patients with mCRC who received combo use of TAS+BEV.', 'interventionNames': ['Drug: Bevacizumab']}], 'interventions': [{'name': 'Regorafenib (BAY73-4506, Stivarga®)', 'type': 'DRUG', 'description': 'Oral multitargeted kinase inhibitor', 'armGroupLabels': ['Cohort R-T']}, {'name': 'TAS-102 (trifluridine and tipiracil, Lonsurf®)', 'type': 'DRUG', 'description': 'Oral cytotoxic chemotherapy', 'armGroupLabels': ['Cohort T-R']}, {'name': 'Bevacizumab', 'type': 'DRUG', 'description': 'VEGFR inhibitor', 'armGroupLabels': ['Cohort R-T', 'Cohort T-R', 'Cohort TAS+BEV']}]}, 'contactsLocationsModule': {'locations': [{'zip': '07981', 'city': 'Whippany', 'state': 'New Jersey', 'country': 'United States', 'facility': 'Many locations', 'geoPoint': {'lat': 40.82454, 'lon': -74.4171}}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO', 'description': 'Availability of this study\'s data will later be determined according to Bayer\'s commitment to the EFPIA/PhRMA "Principles for responsible clinical trial data sharing".
