BACKGROUND
Phosphodiesterase4(PDE4)inhibitionisassociatedwithantiinflammatoryandantifibroticeffectsthatmaybebeneficialinpatientswithidiopathicpulmonaryfibrosis.
METHODS
Inthisphase2,double-blind,placebo-controlledtrial,weinvestigatedtheefficacyandsafetyofBI1015550,anoralpreferentialinhibitorofthePDE4Bsubtype,inpatientswithidiopathicpulmonaryfibrosis.Patientswererandomlyassignedina2:1ratiotoreceiveBI1015550atadoseof18mgtwicedailyorplacebo.Theprimaryendpointwasthechangefrombaselineintheforcedvitalcapacity(FVC)at12weeks,whichweanalyzedwithaBayesianapproachseparatelyaccordingtobackgroundnonuseoruseofanantifibroticagent.
RESULTS
Atotalof147patientswererandomlyassignedtoreceiveBI1015550orplacebo.Amongpatientswithoutbackgroundantifibroticuse,themedianchangeintheFVCwas5.7ml(95%credibleinterval,–39.1to50.5)intheBI1015550groupand–81.7ml(95%credibleinterval,–133.5to–44.8)intheplacebogroup(mediandifference,88.4ml;95%credibleinterval,29.5to154.2;probabilitythatBI1015550wassuperiortoplacebo,0.998).Amongpatientswithbackgroundantifibroticuse,themedianchangeintheFVCwas2.7ml(95%credibleinterval,–32.8to38.2)intheBI1015550groupand–59.2ml(95%credibleinterval,–111.8to–17.9)intheplacebogroup(mediandifference,62.4ml;95%credibleinterval,6.3to125.5;probabilitythatBI1015550wassuperiortoplacebo,0.986).AmixedmodelwithrepeatedmeasuresanalysisprovidedresultsthatwereconsistentwiththoseoftheBayesiananalysis.Themostfrequentadverseeventwasdiarrhea.Atotalof13patientsdiscontinuedBI1015550treatmentowingtoadverseevents.Thepercentagesofpatientswithseriousadverseeventsorsevereadverseeventsweresimilarinthetwotrialgroups.
