Options for effective treatment of cancer-related fatigue are limited, consisting only of non-pharmacologic interventions like physical activity, psychosocial, and mind-body interventions. Recent evidence suggests that vitamin D3 supplementation might alleviate cancer-related fatigue. However, confirmation in a randomized controlled trial is needed.In this multicenter, randomized, double-blind, placebo-controlled trial, 456 colorectal cancer (CRC) patients aged 18 years and older are being recruited in three German rehabilitation clinics. Study inclusion requires hospitalization of at least 3 weeks at such a clinic, a diagnosis of non-metastatic CRC (stage I-III), surgical removal of the tumor within the past 9 months, and season-adapted vitamin D insufficiency or deficiency. Eligible patients are randomly assigned to a personalized regimen of vitamin D3 or placebo for 12 weeks. In the intervention group, a loading dose of 20,000 or 40,000 IU vitamin D3 will be administered daily during the first 11 days, followed by a maintenance dose of 2000 IU daily. Patients will complete questionnaires for secondary outcomes (fatigue subdomains, quality of life and subdomains, depression, functional well-being, and infection frequency). Blood and urine samples will be collected for analyses of safety parameters (hypervitaminosis D, hypercalcemia, hypercalciuria, and renal impairment) and efficacy biomarkers (25-hydroxyvitamin D, HbA1c, white blood cell count, leukocyte subtype counts, serum C-reactive protein, uric acid, creatinine, triglycerides, total, low- and high-density lipoprotein cholesterol).This trial tests whether a personalized vitamin D3 dosing regimen reduces or prevents fatigue among non-metastatic CRC patients by treating the underlying vitamin D deficiency/insufficiency. If efficacy can be confirmed, personalized vitamin D3 supplementation could be used as a tertiary prevention measure in addition to non-pharmacological treatments of cancer-related fatigue in CRC patients. We expect to detect an effect of vitamin D3 supplementation on secondary outcomes like quality of life, depression, functional well-being, infections, inflammatory biomarkers, diabetes mellitus, and dyslipidemia.European Clinical Trials Database: EudraCT-No: 2019-000502-30, January 21, 2019; German Clinical Trials Register (DRKS): DRKS00019907 , April 30, 2019. 000157452 536__ $$0G:(DE-HGF)POF3-313$$a313 - Cancer risk factors and prevention (POF3-313)$$cPOF3-313$$fPOF III$$x0 000157452 588__ $$aDataset connected to CrossRef, PubMed, 000157452 7001_ $$0P:(DE-He78)a1d1b323625dcfa155b477a646cbda52$$aKuznia, Sabine$$b1$$udkfz 000157452 7001_ $$0P:(DE-He78)358cd16fe1dd16be6e4eaf0e76e5ad57$$aLaetsch, Dana Clarissa$$b2$$udkfz 000157452 7001_ $$aCzock, David$$b3 000157452 7001_ $$0P:(DE-He78)bb6a7a70f976eb8df1769944bf913596$$aKopp-Schneider, Annette$$b4$$udkfz 000157452 7001_ $$aCaspari, Reiner$$b5 000157452 7001_ $$0P:(DE-He78)90d5535ff896e70eed81f4a4f6f22ae2$$aBrenner, Hermann$$b6$$eLast author$$udkfz 000157452 773__ $$0PERI:(DE-600)2041352-X$$a10.1186/s12885-020-07219-z$$gVol. 20, no. 1, p. 739$$n1$$p739$$tBMC cancer$$v20$$x1471-2407$$y2020 000157452 909CO $$ooai:inrepo02.dkfz.de:157452$$pVDB 000157452 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)c67a12496b8aac150c0eef888d808d46$$aDeutsches Krebsforschungszentrum$$b0$$kDKFZ 000157452 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)a1d1b323625dcfa155b477a646cbda52$$aDeutsches Krebsforschungszentrum$$b1$$kDKFZ 000157452 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)358cd16fe1dd16be6e4eaf0e76e5ad57$$aDeutsches Krebsforschungszentrum$$b2$$kDKFZ 000157452 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)bb6a7a70f976eb8df1769944bf913596$$aDeutsches Krebsforschungszentrum$$b4$$kDKFZ 000157452 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)90d5535ff896e70eed81f4a4f6f22ae2$$aDeutsches Krebsforschungszentrum$$b6$$kDKFZ 000157452 9131_ $$0G:(DE-HGF)POF3-313$$1G:(DE-HGF)POF3-310$$2G:(DE-HGF)POF3-300$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bGesundheit$$lKrebsforschung$$vCancer risk factors and prevention$$x0 000157452 9141_ $$y2020 000157452 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bBMC CANCER : 2018$$d2019-12-20 000157452 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2019-12-20 000157452 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline$$d2019-12-20 000157452 915__ $$0StatID:(DE-HGF)0310$$2StatID$$aDBCoverage$$bNCBI Molecular Biology Database$$d2019-12-20 000157452 915__ $$0StatID:(DE-HGF)0320$$2StatID$$aDBCoverage$$bPubMed Central$$d2019-12-20 000157452 915__ $$0StatID:(DE-HGF)0501$$2StatID$$aDBCoverage$$bDOAJ Seal$$d2019-12-20 000157452 915__ $$0StatID:(DE-HGF)0500$$2StatID$$aDBCoverage$$bDOAJ$$d2019-12-20 000157452 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bDOAJ : Open peer review$$d2019-12-20 000157452 915__ $$0LIC:(DE-HGF)CCBYNV$$2V:(DE-HGF)$$aCreative Commons Attribution CC BY (No Version)$$bDOAJ$$d2019-12-20 000157452 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search$$d2019-12-20 000157452 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC$$d2019-12-20 000157452 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2019-12-20 000157452 915__ $$0StatID:(DE-HGF)1110$$2StatID$$aDBCoverage$$bCurrent Contents - Clinical Medicine$$d2019-12-20 000157452 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded$$d2019-12-20 000157452 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2019-12-20 000157452 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2019-12-20 000157452 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5$$d2019-12-20 000157452 915__ $$0StatID:(DE-HGF)0561$$2StatID$$aArticle Processing Charges$$f2019-12-20 000157452 915__ $$0StatID:(DE-HGF)0700$$2StatID$$aFees$$d2019-12-20 000157452 9202_ $$0I:(DE-He78)C070-20160331$$kC070$$lC070 Klinische Epidemiologie und Alternf.$$x0 000157452 9200_ $$0I:(DE-He78)C070-20160331$$kC070$$lC070 Klinische Epidemiologie und Alternf.$$x0 000157452 9201_ $$0I:(DE-He78)C070-20160331$$kC070$$lC070 Klinische Epidemiologie und Alternf.$$x0 000157452 9201_ $$0I:(DE-He78)C060-20160331$$kC060$$lC060 Biostatistik$$x1 000157452 9201_ $$0I:(DE-He78)C120-20160331$$kC120$$lPräventive Onkologie$$x2 000157452 9201_ $$0I:(DE-He78)HD01-20160331$$kHD01$$lDKTK HD zentral$$x3 000157452 980__ $$ajournal 000157452 980__ $$aVDB 000157452 980__ $$aI:(DE-He78)C070-20160331 000157452 980__ $$aI:(DE-He78)C060-20160331 000157452 980__ $$aI:(DE-He78)C120-20160331 000157452 980__ $$aI:(DE-He78)HD01-20160331 000157452 980__ $$aUNRESTRICTED
