Trial Outcomes & Findings for Study of Modified Recombinant Factor VIII (OBI-1) in Subjects With Acquired Hemophilia A (NCT NCT01178294)

NCT ID: NCT01178294

Last Updated: 2021-05-13

Results Overview

The initial serious ("qualifying") bleeding episode for each subject was analyzed for the primary efficacy outcome measure. A 'positive response' is defined as 'effective' (bleeding stopped with clinical control and FVIII levels of 50% or higher ) or 'partially effective' (bleeding reduced with clinical stabilization and FVIII levels of 20% or higher) control of bleeding, as determined by the investigator using a 4-point rating scale (effective - partially effective - poorly effective - not effective). 'Poorly effective' is defined as 'bleeding slightly reduced or unchanged and FVIII levels of less than 50%'. 'Not effective' is defined as 'bleeding worsening and FVIII levels of less than 50%'.

Participant Flow

Enrollment was conducted at 12 clinical sites in 4 countries (USA, Canada, UK, India). Eight sites enrolled subjects under Protocol OBI-1-301 only. Two US sites enrolled subjects under the expanded access protocol OBI-1-301a and subsequently under protocol OBI-1-301. Another 2 US sites enrolled subjects under OBI-1-301a only.

29 subjects were enrolled and all were treated with OBI-1. Data from the expanded access subjects (Protocol 301a, n= 4) are included with the data from subjects enrolled under Protocol OBI-1-301 (n=25). 10 subjects discontinued prematurely and 18 completed the study. For one subject, the completion status could not be verified.

PRIMARY outcome

Timeframe: 24 hours after initiation of treatment

Population: Intent to Treat (ITT) population = 29 subjects with initial serious bleeding episodes

The initial serious ("qualifying") bleeding episode for each subject was analyzed for the primary efficacy outcome measure. A 'positive response' is defined as 'effective' (bleeding stopped with clinical control and FVIII levels of 50% or higher ) or 'partially effective' (bleeding reduced with clinical stabilization and FVIII levels of 20% or higher) control of bleeding, as determined by the investigator using a 4-point rating scale (effective - partially effective - poorly effective - not effective). 'Poorly effective' is defined as 'bleeding slightly reduced or unchanged and FVIII levels of less than 50%'. 'Not effective' is defined as 'bleeding worsening and FVIII levels of less than 50%'.

SECONDARY outcome

Timeframe: At the time of final treatment dosing (varied from participant to participant depending on bleeding episodes)

Population: ITT population = 29 subjects with initial serious bleeding episodes (BEs)

Treatment success was defined as control of qualifying bleeding episode at the time of final treatment dosing. A serious bleeding episode was considered 'successfully controlled' if the investigator had checked 'completed OBI-1 therapy as treatment success' on the eCRF.
