From: A roadmap to using historical controls in clinical trials – by Drug Information Association Adaptive Design Scientific Working Group (DIA-ADSWG)

Drug CandidateCarglumic Acid or CARBAGLUProtein C Concentrate (Human) or CEPROTINLepirudin or REFLUDANAntithrombin [Recombinant] or ATRYN
IndicationHyper-ammonaemiaProtein C deficiencyImmunologic type of Heparin-associated thrombocytopeniaHereditary anti-thrombin deficient patients

Other treatmentsNoNoNoNo
Study DesignRetrospective Case SeriesN/AUncontrolled studyTwo prospective, single-arm, open-label studies
Number of subjects23 subjects18 subjectsTwo studies with 39 and 33 Subjects31 subjects
EndpointAmmonia levelsResponse for thromboembolic eventsPlatelet count recoveryIncidence of thromboembolic events
Type of HCNatural history dataN/ARegistry data which PI establishedProspectively designed retrospective chart review
Source of the HCSubject at baselineN/ASubjects not treated with recombinant hirudin 
Size of HC23 subjects21 subjects91 subjects35 Subjects
Method of applicationDescriptive statisticsDescriptive StatisticsDirect comparisonMatching
Note  HC was used only for secondary endpoint due to the less availability of platelet data 
Drug CandidateAnagrelide or AGRYLINAlglucosidase Alfa or MYOZYME/LUMIZYMEMiglustat or ZAVESCABlinatumomab or BLINCYTO
IndicationReduction of the elevated platelet count, thrombosis and ameliorate-associated symptoms.Pompe diseaseType I Gaucher diseaseAdults relapsed/refractory Acute Lymphoblastic Leukaemia
Prevalence of the diseaseN/A1/40,000 live births1/100,0001–2/100,000 adults
Other treatmentsNoNoAvailableNo
Study DesignSelf-controlled studyRCT with two dose groupsSelf-controlled studySingle arm trial

EndpointN/AInvasive ventilator-free survival and survival ratePercentage change from baseline in liver organ volumeComplete remission
Type of HCNatural history data at baselineNatural history data (Cross-sectional NH)Natural history data at baselineSeveral kinds of data
Source of the HCSubject at baselineNatural history dataSubject at baselineInvestigator database
Size of HCAbout 300 subjects62 subjects82 subjects1112 subjects
Method of applicationN/ADirect comparison for non-inferiority inference.Descriptive StatisticsHC was used to show the validity of efficacy threshold by meta analytic approach.
Note Historical data collected over a 20-year span and time trend observed. For EMA, analysis with propensity score was also performed.
Drug CandidateArsenic trioxide or TRISENOXEteplirsen or EXONDYS 51Elbasvir and Grazoprevir or ZEPATIERNitisinone or ORFADIN

Size of HC27 subjects13 subjectsDepending on the trials108 subjects
Method of applicationJust showed as referenceDirect comparisonOne sample testing.
HC was used for efficacy threshold.
