Congenital Plasminogen Deficiency, Hypoplasminogenemia
Conditions
Brief summary
This is a Phase 2/3 pivotal study to evaluate pharmacokinetics (PK), efficacy, and safety of Prometic Plasminogen (Human) Intravenous Lyophilized Solution, the investigational medicinal product (IMP), in pediatric and adult subjects with hypoplasminogenemia.
Detailed description
This is a Phase 2/3, open-label, repeat-dose study of the PK, efficacy, and safety of the IMP, in pediatric and adult subjects with hypoplasminogenemia. The study consists of a screening period and 3 treatment segments (Segment 1,2, and 3). Subjects who have documented individual PK profiles do not need to undergo Segment 1 and can proceed directly to Segment 2. Subjects in Segment 1 will receive a single dose of 6.6 mg/kg IMP infusion. Blood samples for PK analysis will be drawn prior to infusion and subsequently through 96 hours after the infusion to establish individual PK profiles. The sample drawn prior to infusion will be used to measure the subject's baseline anti-plasminogen antibody, plasminogen activity and antigen as well as D-dimer levels. The resulting PK profile will be used to determine each subject's dosing interval in Segment 2. Based on individual PK profiles from Segment 1 subjects will receive 6.6 mg/kg IMP infusion every second, third, or fourth day for 12 weeks in Segment 2. For subjects who directly enter Segment 2, baseline assessments will be conducted before the first dose of IMP, including a blood sample to measure the baseline anti-plasminogen antibody, plasminogen activity and antigen as well as D-dimer levels. Subjects will visit the study sites on Week 1 and subsequently every 4 weeks, and receive the IMP infusion at the study site. Blood samples will be obtained at each study visit at Weeks 4, 8 and 12 and by a home health nurse at Weeks 2, 6 and 10. Subjects will undergo clinical assessments of the disease, including but not limited to: photographic measurements of visible lesions, spirometry for subjects with pulmonary involvement, and imaging study of nonvisible lesions, as applicable. Plasma samples will be drawn before IMP administration every 2 weeks to measure the trough levels of plasminogen activity and antigen, and D-dimer. At the end of Segment 2, subjects will have the option to participate in Segment 3 where they will continue to receive IMP for an additional 36 weeks in Norway, and until product licensing or study termination by the sponsor for subjects in the United States. Subjects will return to the study sites for assessments every 3 months to monitor subjects' clinical status and plasminogen trough levels. Subjects at the Norway site in Segment 3 should return to the study site for a safety follow-up visit 30 days after the final IMP dose. Due to the delay in product approval, subjects at the US site in Segment 3 will be allowed to enroll in treatment protocol 2002C018G and continue ongoing IMP treatment without any break in treatment. If subjects decide to not enter treatment protocol 2002C018G, then they will stop IMP and return to the study site for a safety follow-up visit 30 days after the final IMP dose. The primary objective of this study is to achieve an increase of individual trough plasminogen activity by at least an absolute 10% (i.e., 10 U/dL) from baseline during the 12 weeks of plasminogen replacement therapy in Segment 2; and to evaluate the efficacy of plasminogen replacement therapy on clinically evident or visible symptoms of hypoplasminogenemia during the 48 weeks of dosing in Segments 2 and 3.

Number of Participants With Improved Quality of Life (QOL) Score After 48 Weeks of Study Treatment
Quality of life score (QOL) was measured at baseline and at 12 and 48 weeks after study drug treatment. For the QOL assessment, participants were asked to rate their overall QOL using an 11-point scale (0 = non-functioning, 10 = normal; The QOL scale was adapted from a scale developed by the American Chronic Pain Association.
Time frame: 48 weeks
Population: Efficacy Population Week 48-Segment 3 included all 15 enrolled participants who completed the Week 48 visit at the time of the data cut-off date of 14Dec2017

Overall Clinical Success in Number and Size of Lesions as Measured by Photographic or Other Imaging Modality Depending on the Organ System Affected or Change in Affected Organ Functionality at 12 Weeks
Overall clinical success was defined as 50% of participants with visible or other measurable lesions achieving at least a 50% improvement in lesion number/size or functionality impact from baseline. Visible lesions were defined as lesions that could be imaged and analyzed with digital photography. Non-visible lesions were defined as lesions whose dimensions could have been assessed by medical imaging studies (eg, computed tomography, magnetic resonance imaging, ultrasound, etc) or functional assessments (eg, spirometry, audiogram, oximetry, etc).Visible lesions that had both a length and width as measured by the 1mm scale, were referred to as measurable lesions, and visible lesions that were too small to measure by the 1mm scale (length and/or width could not have been measured) were referred to as non-measurable lesions.
Time frame: 12 Weeks
Population: Efficacy population week 12 included all 15 enrolled participants who completed the week 12 visit. All 15 participants were assessed, however only 11 participants had visible and/or non-visible lesions at baseline.
