1.Male subjects =12 and =65 years of age at the time of informed consent. Enrollment of adolescents (aged =12 to <18 years) will be deferred until at least 12 adult subjects from each SerpinPC treatment regimen have completed at least 12 weeks of dosing in Part 1 and the safety profile of SerpinPC has been assessed
2.Capable of providing written informed consent (adolescent assent and parental/guardian/legal representative consent when appropriate) for participation and having the opportunity to discuss the study with the investigator or delegate
3.Historically documented severe HemA (defined as fVIII <0.01 IU/mL [ <1%]), with or without inhibitors, or moderately severe to severe HemB (defined as fIX =0.02 IU/mL [=2%]), without high titer inhibitor (high titer inhibitor defined as =5 BU/mL) and not requiring current treatment with bypass agents
4.Subject is currently included in a prophylaxis program. Fulfillment of this criterion will be based on investigator’s judgment of adequate prophylaxis regimen Subject is undergoing an on-demand treatment regimen and must have had =6 documented acute bleeding episodes (spontaneous or traumatic) that required treatment during the 6 months before Screening Irrespective of the treatment program that the subject is currently undergoing, they must be willing to remain in the same program for the duration of the prospective observational period
5.Subjects who are currently in a prophylaxis program must be willing to stop prophylaxis (including episodic prophylaxis for sporting events) before the first dose of SerpinPC
6.For Part 1: At least 12 weeks of prospective documentation of bleeding episodes in the AP-105 non-interventional study before SerpinPC dosing or willing to complete a 12-week observational period (at minimum) in AP-0102
7.For Part 2: At least 24 weeks of prospective documentation of bleeding episodes in the AP-0105 non-interventional study before SerpinPC dosing or willing to complete a 24-week observational period (at minimum) in AP-0102
8.No bleeding in the 7 days before Baseline (the prospective observation period can be extended by 10 days if there is an ongoing active bleed)
9.D-dimer of =750 µg/L; in cases where there is a resolving bleed, the exclusion threshold is =1750 mg/L at Screening and Pre-dosing visits
10.Adequate hematologic function, defined as a platelet count of =100,000/µL (=100 × 109/L) and hemoglobin level of =10 g/dL (=100 g/L or =6.206 mmol/L) at Screening and Pre-dosing visits
11.Adequate hepatic function, defined as a total bilirubin level of =1.5 × ULN (excluding Gilbert syndrome) and aspartate aminotransferase and/or alanine aminotransferase of =3 × ULN at Screening and Pre-dosing visits; no clinical signs or known laboratory or radiographic evidence consistent with cirrhosis of the liver
12.Adequate renal function, defined as a serum creatinine level of =2.0 × ULN at Screening and Pre-dosing visits
13. Able to use a diary to document bleeding events and medication usage
14.Sexually active subjects with a partner who could become pregnant should agree to use effective contraception for the duration of the study
1.Known severe thrombophilia (defined as antithrombin deficiency and/or protein S deficiency and/or protein C deficiency)
2.Subject with previous factor VIII or factor IX inhibitor who responded to immune tolerance induction and remains on prophylactic factor concentrate
3.Previous deep vein thrombosis, pulmonary embolism, myocardial infarction, or stroke
4.History of intolerance to SC injections
5.Uncontrolled hypertension (systolic blood pressure >160 mm Hg; diastolic blood pressure >100 mm Hg)
6.Weight >150 kg OR body mass index >40 kg/m2
7.Has active cancer and/or requires therapy for cancer, except for basal cell carcinoma
8.Participation in another clinical trial (except for AP-0105) during the 30 days before Screening
9.Use of emicizumab in the 24 weeks before Baseline (Day 0)
10.Prior, ongoing, or planned treatment with gene therapy for hemophilia
11.Any major medical, psychological, or psychiatric condition that could cause the subject to be unsuitable for the study or could interfere with the interpretation of the study results
12.History of or other evidence of recent alcohol or drug abuse as determined by the investigator (in the 12 months before Screening)
13.Known HIV infection with CD4 count (or T-cell count) of <200 cells/µL within 24 weeks before Screening and Pre-dosing visits. Patients with HIV infection who have CD4 >200 and meet all other criteria are eligible
14.Current or planned treatment with anticoagulant or antiplatelet drugs
15.Is planning to donate/bank sperm during SerpinPC treatment AND within 30 days of last dose of SerpinPC
16.16. Any other significant conditions or comorbidities that, in the opinion of the investigator, would make the subject unsuitable for enrollment or could interfere with participation in or completion of the study
