E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to determine the efficacy of a predefined vitamin D dosing regimen on the prevalence of vitamin D insufficiency in MM patients. |
Het primaire doel van dit onderzoek is het bepalen van de effectiviteit van een vooraf gedefinieerd vitamine D-doseringsschema op de prevalentie van vitamine D-insufficiëntie bij patiënten met multipel myeloom. |
|
E.2.2 | Secondary objectives of the trial |
Secondary objectives are to detect the influence of several variables (age, gender, cumulative dose, type of treatment, race, the use of alcohol and the presence of diabetes mellitus) on the chance of successfully increasing the vitamin D serum concentration; to determine the efficacy of vitamin D supplementation on the prevalence and severity of PN in MM patients; to determine differences between the effect of vitamin D supplementation on the prevalence and severity of PN for each subgroup: treatment and different drugs used for MM (drugs that can be used are bortezomib, carfilzomib, daratumumab, elotuzumab, ixazomib, lenalidomide, panobinostat, pomalidomide, thalidomide and vincristine). |
Secundaire doelen zijn het detecteren van de invloed van verschillende variabelen (leeftijd, geslacht, cumulatieve dosis, type behandeling, ras, het gebruik van alcohol en de aanwezigheid van diabetes mellitus) op de kans op het succesvol verhogen van de vitamine D-serumconcentratie; het bepalen de effectiviteit van vitamine D-suppletie op de prevalentie en ernst van perifere neuropathie in MM patiënten; het bepalen van verschillen in het effect van vitamine D-suppletie op de prevalentie en ernst van perifere neuropathie voor elke sungroep: behandeling en elk geneesmiddel dat bij multipel myeloom gebruikt wordt (bortezomib, carfilzomib, daratumumab, elotuzumab, ixazomib, lenalidomide, panobinostat, pomalidomide, thalidomide en vincristine). |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Subjects are (newly) diagnosed with smoldering or symptomatic multiple myeloma. Subjects must be over 18 years of age. Subjects must be able to give informed consent. Subjects with a 25-hydroxyvitamin D level ≤75 nmol/l. |
Patiënten die (nieuw) gediagnosticeerd zijn met asymptomatisch of symptomatisch multipel myeloom. Patiënten die 18 jaar of ouder zijn. Patiënten die in staat zijn om informed consent te geven. Patiënten met een 25-hydroxyvitamine D-spiegel ≤75 nmol/l |
|
E.4 | Principal exclusion criteria |
Contraindications for the use of vitamin D: Hypersensitivity to the active substance(s) or to any of the excipients; Hypercalcaemia and/or hypercalciuria; Nephrolithiasis and/or nephrocalcinosis; Serious renal impairment; Hypervitaminosis D; Pseudohypoparathyroidism. The use of vitamin D tablets or multivitamin tablets containing vitamin D |

E.5.2 | Secondary end point(s) |
Secondary endpoints are the influence of several variables (age, gender, cumulative dose, type of treatment, race, the use of alcohol and the presence of diabetes mellitus) on the chance of successfully increasing the vitamin D serum concentration; the efficacy of vitamin D supplementation on the prevalence and severity of PN in vitamin D-deficient MM patients; differences between the effect of vitamin D supplementation on the prevalence and severity of PN for each subgroup: treatment and different drugs used for MM (drugs that can be used are bortezomib, carfilzomib, daratumumab, elotuzumab, ixazomib, lenalidomide, panobinostat, pomalidomide, thalidomide and vincristine) |
