Eligibility Criteria

Sex: All

Age: 18 - 70

Healthy Volunteers: Not accepted

Inclusion Criteria:

1. Male or female participants ages 18-70 years old.
2. Diagnosis of aFXD associated with AL amyloidosis with FX:C ≤ 50 IU/dL.
3. Woman of Childbearing Potential (defined in Appendix 2) and men of reproductive potential who agree to use an effective contraception measure during the study.

Exclusion Criteria:

1. Female participants that are pregnant or lactating.
2. Presence of FX inhibitors.
3. Uncontrolled arterial hypertension.
4. On anticoagulant therapy (not antiplatelets), unstable heart disease, clinically significant thrombotic event in the past 180 days or any other condition that the Investigator believes is likely to interfere with evaluation of the study drug or with satisfactory conduct of the trial.
5. Any factor X containing product taken within 2 weeks of first Coagadex® administration.
6. Participation in another interventional clinical study with an investigational drug, biologic, or device within 30 days prior to screening.
7. Hemodynamically unstable due to any cause or even after blood transfusion, fluid resuscitation and pharmacologic or volume replacement pressor therapy.

Interventions and Outcome Measures

Arms

experimental: On-Demand Treatment Cohort

Participants without an active bleeding event will enter the Run-In Period, which lasts up to 180 days. Upon a bleeding event participants will receive a first dose of 40 IU/kg of Coagadex®. Additional dose(s) will be based on the incremental recovery (IR). (If an allowed Emergent Surgery becomes necessary in the Run-In Period, the participant will cross over into the Surgery/Invasive Procedures Cohort.)

experimental: Surgery/Invasive Procedures Cohort

Participants enrolled at least 3 weeks prior to a scheduled surgical intervention will undergo pharmacokinetic sampling. The dose of Coagadex® will be determined based on the patient's PK profile. (During this 3-week period, if the participant develops an acute bleed, they will cross over into the On-Demand Treatment Cohort for treatment.)

Interventions

Coagadex(R)

Coagulation Factor X (Human)

Primary outcome measure

  • Proportion of bleeding events responsive to Coagdex® therapy at 72 hours after initiation of treatment in the On-Demand Treatment Cohort [ Time Frame: at 72 hours ]
  • Proportion of bleeding events responsive to Coagdex® therapy at 72 hours after initiation of treatment in the Surgery/Invasive Procedures Cohort [ Time Frame: at 72 hours ]
