COAGADEX is a plasma-derived, sterile, purified concentrate of human coagulation Factor X that contains sucrose as a stabilizer. It is formulated as a lyophilized powder for solution for intravenous administration. When reconstituted with Sterile Water for Injection, COAGADEX contains nominally (approximately) 100 IU/mL of coagulation Factor X and the following inactive ingredients: chloride, phosphate, citrate, sucrose and sodium. Each vial of COAGADEX is labeled with the actual Factor X activity/content expressed in IU per vial. Factor X activity in IU is determined using an in vitro chromogenic assay and a Factor X concentrate reference standard calibrated against the WHO 3rd International Standard for Blood Coagulation Factors II and X, Concentrate.
COAGADEX contains no added biological components such as heparin, albumin or anti-thrombin. The content of Factor II and Factor IX are ≤ 1 IU/mL of the reconstituted product. Factor Xa and Factor IIa were not detectable by Non-activated Partial Thromboplastin Time (NaPTT) or Fibrinogen Clotting Time (FCT) tests for potential thrombogenicity, and comprised < 10 parts per million by weight when tested by more sensitive analytical methods. The specific activity of COAGADEX is typically 80-137 IU per mg protein. The product contains no preservatives.
COAGADEX is manufactured from plasma, obtained from healthy US donors, who have passed viral screening tests. All donors are subjected to medical examinations, laboratory tests, and a review of their medical history before being allowed to donate blood or plasma.
All plasma donations are screened for antibody to human immunodeficiency virus (HIV)-½, hepatitis C virus (HCV), and hepatitis B surface antigen (HBsAg). Additional testing of donations is carried out in plasma mini-pools (512 donations per pool) with nucleic acid amplification testing (NAT) for HIV, hepatitis B virus (HBV), hepatitis C virus (HCV), hepatitis A virus (HAV) and human parvovirus B19. Furthermore, each manufacturing pool is tested to be negative for HBsAg and anti-HIV-½ antibodies. Also, manufacturing pools are non-reactive by nucleic acid test for HAV, HBV, HCV, and HIV-1. The limit for human parvovirus B19 in the manufacturing pools is set not to exceed 104 IU/mL.
Three processing steps specifically designed to remove or inactivate viruses are:
The capacity of the manufacturing process to remove and/or inactivate enveloped and non-enveloped viruses has been validated by laboratory spiking studies on a scaled-down process model. Overall virus reduction was calculated only from steps that were mechanistically independent from each other. Table 2 presents the contribution of each process step to virus reduction and the overall process reduction.

COAGADEX, Coagulation Factor X (Human), is a plasma-derived human blood coagulation Factor indicated in adults and children with hereditary Factor X deficiency for:
Perioperative management of bleeding in major surgery in patients with severe hereditary Factor X deficiency has not been studied.
For intravenous use after reconstitution only
Estimated Increment of Factor X (IU/dL or % of normal) = [Total Dose (IU)/Body Weight (kg)] × 2
The dose to achieve a desired in vivo peak increase in Factor X level may be calculated using the following formula:
Dose (IU) = Body Weight (kg) × Desired Factor X Rise (IU/dL or % of normal) × 0.5
Note: The desired Factor X rise is the difference between the patient's plasma Factor X level and the desired level. The dosing formula is based on the observed recovery of approximately 2 IU/dL per IU/kg for adults and adolescents at least 12 years of age.
Estimated Increment of Factor X (IU/dL or % of normal) = [Total Dose (IU)/Body Weight (kg)] × 1.7
The dose to achieve a desired in vivo peak increase in Factor X level may be calculated using the following formula:
Dose (IU) = Body Weight (kg) × Desired Factor X Rise (IU/dL) × 0.6
Prophylaxis of bleeding episodes
| Age | Initial dose | Further management |
| Children: Less than 12 years of age | 40 IU/kg twice weekly | Due to inter-and intra-patient variability, it is recommended that trough blood levels of Factor X should be monitored at intervals, especially in the first weeks of therapy or after dosages changes. Adjust dosage regimen to clinical response and trough levels of Factor X of at least 5 IU/dL. Do not exceed a peak level of 120 IU/dL. |
| Adults and adolescents: 12 years of age or older | 25 IU/kg twice weekly |
On–demand treatment and control of bleeding episodes
| Age | Initial dose | Further management |
| Children: Less than 12 years of age | 30 IU/kg | Infuse COAGADEX when the first sign of bleeding occurs [see Clinical Trial Experience]. Repeat at intervals of 24 hours until the bleed stops. |
| Adults and adolescents: 12 years of age or older | 25 IU/kg |
Perioperative management of bleeding
| Age | Initial dose | Further management |
| Children: Less than 12 years of age | Calculate dose (IU) using 0.6 as shown in the 'Dose' formula (Dose). The increment of Factor X can be estimated using in vivo recovery value of 1.7 (see formula above) | Measure post-infusion plasma Factor X levels for each patient before and after surgery to ensure that hemostatic levels are obtained and maintained. Pre-surgery: calculate the dose of COAGADEX to raise plasma Factor X levels to 70-90 IU/dL Post-surgery: Repeat dose as necessary to maintain plasma Factor X levels at a minimum of 50 IU/dL until the patient is no longer at risk of bleeding due to surgery |
| Adults and adolescents: 12 years of age or older | Calculate dose (IU) using 0.5 as shown in the 'Dose' formula (Dose) The increment of Factor X can be estimated using in vivo recovery value of 2.0 (see formula above) |

The most common adverse drug reactions (frequency ≥ 5% of subjects) observed in clinical trials were infusion site erythema, infusion site pain, fatigue, and back pain.
As clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trial of another drug and may not reflect the rates observed in clinical practice.
During the clinical development of COAGADEX involving three multicenter, open-label, non-randomized clinical studies, 27 individual subjects with hereditary Factor X deficiency received at least one dose of COAGADEX.
Sixteen subjects aged 12 to 58 years with moderate to severe hereditary Factor X deficiency (basal FX:C < 5 IU/dL) received doses of COAGADEX for pharmacokinetic evaluation, on-demand treatment for control of bleeding episodes, and/or perioperative management of minor surgical or dental procedures. A total of 468 infusions were administered, including 242 for on-demand treatment and control of bleeding episodes, 6 for perioperative management and 31 for PK assessments. Spontaneous, traumatic and menorrhagic bleeding episodes were treated with an on-demand dose of 25 IU/kg for up to 2 years.Two subjects aged 55 and 59 years with mild hereditary Factor X deficiency (basal FX:C 6 IU/dL and 8 IU/dL) received COAGADEX for perioperative management of four major surgical procedures. There were 40 exposure days to COAGADEX.
Six adverse reactions were reported in 2 of the 18 subjects. These were infusion site erythema (2 reports in 1 subject [5.6%]), fatigue (2 reports in 1 subject [5.6%]), back pain (1 report [5.6%]) and infusion site pain (1 report [5.6%]).
In a separate study, nine children (aged 2 to 11 years), of whom four were less than 6 years of age, received 537 (mean 59.7) doses of COAGADEX as routine prophylaxis of bleeding episodes during a period of at least 6 months. In addition, 22 infusions were given to treat a bleed, equivalent to 2.1 bleeds per subject per year. There were no adverse drug reactions in this study.
All subjects (adults and children) underwent Factor X inhibitor testing (inhibitor screen and Nijmegen-Bethesda assay) at baseline, end of study and at 3-monthly intervals in between. For subjects who underwent surgery, inhibitor testing was done pre-surgery and on discharge. All inhibitor tests were negative. Additionally, comparison of pharmacokinetic (PK) parameters at the repeat PK assessment with those at first dose did not suggest development of any inhibitors to Factor X.
The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, it may be misleading to compare the incidence of antibodies to COAGADEX in the studies described above with the incidence of antibodies in other studies or to other products.
Drug interaction studies have not been performed. Use with caution in patients who are receiving other plasma products that may contain Factor X (e.g. fresh frozen plasma, prothrombin complex concentrates). Based on the mechanism of action, COAGADEX is likely to be counteracted by direct and indirect Factor Xa inhibitors [see CLINICAL PHARMACOLOGY].
Included as part of the "PRECAUTIONS" Section
Allergic type hypersensitivity reactions, including anaphylaxis, are possible. Early signs of hypersensitivity reactions including angioedema, infusion site inflammation (e.g. burning, stinging, erythema), chills, cough, dizziness, fever, flushing, generalized urticaria, headache, hives, hypotension, lethargy, musculoskeletal pains, nausea, pruritus, rash, restlessness, tachycardia, tightness of the chest, tingling, vomiting, wheezing. If hypersensitivity symptoms occur, discontinue use of the product immediately and administer appropriate emergency treatment.
COAGADEX contains traces of human proteins other than Factor X.
The formation of neutralizing antibodies (inhibitors) to Factor X may occur. Monitor all patients treated with COAGADEX for the development of inhibitors by appropriate clinical observations and laboratory tests. If expected Factor X activity levels are not attained, or if bleeding is not controlled with an expected dose, perform an assay that measures Factor X inhibitor concentration.
As COAGADEX is made from human blood, it may carry a risk of transmitting infectious agents, e.g. viruses, the variant Creutzfeldt-Jakob disease (vCJD) agent and, theoretically, the Creutzfeldt-Jakob disease (CJD) agent. There is also the possibility that unknown infectious agents may be present in the product. The risk that the product will transmit viruses has been reduced by screening plasma donors for prior exposure to certain viruses, by testing for the presence of certain current virus infections, and by inactivating and removing certain viruses during manufacture. Despite these measures, this product may still potentially transmit diseases.
All infections suspected by a physician possibly to have been transmitted by this product should be reported by the physician or other healthcare providers to BPL USA Inc. at 1-844-427-5872 or [email protected].
Monitor plasma Factor X activity by performing a validated test (e.g. one-stage clotting assay), to confirm that adequate Factor X levels have been achieved and maintained [see DOSAGE AND ADMINISTRATION].
Monitor for the development of Factor X inhibitors. Perform a Nijmegen-Bethesda inhibitor assay if expected Factor X plasma levels are not attained, or if bleeding is not controlled with the expected dose of COAGADEX. Use Nijmegen-Bethesda Units (BU) to report inhibitor levels.
Nonclinical studies evaluating the carcinogenic or mutagenic potential of COAGADEX have not been conducted. No animal studies regarding impairment of fertility following COAGADEX dosing were conducted; however, no macroscopic or microscopic pathologies in reproductive organs were observed in rats dosed every other day with 6 times the maximum recommended clinical dose of 60 IU/kg COAGADEX for 28 days.
There is limited data with COAGADEX in pregnant women to inform on drug-associated risk. Animal reproduction studies have not been conducted using COAGADEX. It is not known whether COAGADEX can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.
There is no information regarding the presence of COAGADEX in human milk, the effects on the breast-fed infant, or the effects on milk production. The developmental and health benefits of breast-feeding should be considered along with the mother's clinical need for COAGADEX and any potential adverse effects on the breast-fed infant from COAGADEX or from the underlying maternal condition.
COAGADEX has been studied in 9 young children and 2 adolescents less than 16 years of age (2.1, 6.1, 12.3, 14).
Clinical studies of COAGADEX did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
One case of accidental overdosage was reported in the clinical trials, in which a subject received approximately 80 IU/kg Factor X to treat a bleed. No adverse events were reported relating to this overdose.
COAGADEX is contraindicated in patients who have had life-threatening hypersensitivity reactions to COAGADEX [see DESCRIPTION].
COAGADEX temporarily replaces the missing Factor X needed for effective hemostasis. Factor X is an inactive zymogen, which can be activated by Factor IXa (via the intrinsic pathway) or by Factor VIIa (via the extrinsic pathway). Factor X is converted from its inactive form to the active form (Factor Xa) by the cleavage of a 52-residue peptide from the heavy chain. Factor Xa associates with Factor Va on a phospholipid surface to form the prothrombinase complex, which activates prothrombin to thrombin in the presence of calcium ions. Thrombin then acts upon soluble fibrinogen and Factor XIII to generate a cross-linked fibrin clot.
The administration of COAGADEX increases plasma levels of Factor X and can temporarily correct the coagulation defect in these patients, as reflected by decrease in the aPTT and PT.
In a clinical study of COAGADEX in subjects with severe or moderate Factor X deficiency (basal FX:C < 5 IU/dL), the pharmacokinetics of COAGADEX were assessed after intravenous infusion (mean [range] infusion rate 5.9 [1.3-17.1] mL/min) of 25 IU/kg COAGADEX. Pharmacokinetic (PK) parameters were calculated from plasma Factor X:C activity measurements after subtraction of the pre-dose value. The PK assessment was repeated at least 6 months after the first dose. The PK parameters following a single dose are summarized in Table 3. The pharmacokinetics of COAGADEX were similar following the single and repeat dosing.

Studies were not conducted to evaluate the impact of gender or renal/hepatic function on the pharmacokinetics of COAGADEX.
In a multicenter, open-label, non-randomized clinical trial to evaluate the pharmacokinetics, safety and efficacy of COAGADEX, 16 subjects with moderate to severe hereditary Factor X deficiency (FX:C < 5 IU/dL) received a dose of 25 IU/kg COAGADEX to treat spontaneous, traumatic and menorrhagic bleeding episodes. If hemostasis was not achieved with a single dose of COAGADEX, additional doses could be given until the bleed stopped. Subjects could also continue with treatment after the bleed had stopped to reduce the risk of recurrence of a given bleed. Subjects were aged 12 to 58 years, including 6 pediatric subjects aged 12 to 17 years. Six subjects were male, 10 were female, and 12 were Caucasian.
The efficacy of COAGADEX in treating bleeding episodes was assessed by the subject and/or investigator for each new bleeding episode, using a bleedspecific ordinal rating scale of excellent, good, poor and unassessable for each type of bleed (overt, covert or menorrhagic). Overt bleed: 'excellent' if bleeding stopped within 12 hours with a single dose; 'good' if within 24 hours with ≤2 doses. Covert bleed: 'excellent' if bleeding stopped within 48 hours with 1 or 2 doses; 'good' if within 48 hours with ≤3 doses. Menorrhagic bleed: 'excellent' if ≤2 doses within 48 hours; 'good' if 2 doses over >48 hours. Each bleed was reviewed by a Data Review Committee for its suitability for the efficacy evaluation. Of the 208 bleeding episodes treated with COAGADEX, 187 bleeding episodes in 15 subjects were evaluated for efficacy. Of these 187 bleeding episodes, 79 (42%) occurred spontaneously, 47 (25%) were traumatic and 61 (33%) were menorrhagic. Seventy three (39%) were mucosal in origin, 63 (34%) were joint bleeds, 26 (14%) were muscle bleeds, and 25 (13%) were located elsewhere.
Ninety eight (53%) were major bleeding episodes, and 88 (47%) were minor bleeds (one bleed not assessed). COAGADEX was considered to be good (7%) or excellent (91%) in treating 98% of bleeding episodes. Of the 187 bleeding episodes in the efficacy analysis, a total of 155 bleeds (83%) were treated with one infusion, 28 bleeds (15%) with two infusions, 3 bleeds (2%) with three infusions and 1 bleed (0.5%) with four infusions. The mean dose per infusion and total dose of COAGADEX were 25.4 IU/kg and 30.4 IU/kg, respectively. Four bleeding episodes in two subjects were considered treatment failures.
The recommended dose of 25 IU/kg COAGADEX to treat a bleed was maintained during the study for 14 of the 16 subjects. The other two subjects used doses up to 30 IU/kg and 33 IU/kg.
In a multicenter, open-label, non-randomized clinical trial, the use of COAGADEX in routine prophylaxis of bleeding episodes was evaluated in nine children aged less than 12 years of age. The mean age was 7.3 (range 2.6 to 11.9) years. Eight subjects had severe FX deficiency and the other had moderate deficiency. Four subjects were between 0 and 5 years of age and five were between 6 and 11 years of age inclusive. The majority of subjects were Asian (7; 77.8%) and the remainder were Caucasian/White (2; 22.2%). After the first dose of COAGADEX 50 IU/kg, given at a rate not exceeding 3 mL/minute, all subjects underwent a 30-minute post-dose incremental recovery assessment. Routine prophylaxis was started on Day 2 or 3 with unit doses of 40-50 IU/kg and during the first 6 weeks trough levels of Factor X were measured to adjust the dosage regimen to maintain a trough level of at least 5 IU/dL. At the end of the study (at least 6 months and at least 50 exposure days) a repeat 30-minute incremental recovery was performed. A total of 537 (mean 59.7 per subject) prophylactic infusions were administered. The median prophylactic dose per infusion per subject was 39.60 IU/kg (mean 38.76 IU/kg), and ranged from 18.0 to 47.3 IU/kg. Median and mean doses per infusion in the four children less than 6 years of age were both 40.1 IU/kg (95% CI 30.70, 49.57) and in the five children 6 to 11 years of age inclusive, median dose was 39.6 IU/kg and mean dose was 37.7 IU/kg (95% CI: 23.42, 51.91). The median dosing interval for all of the nine children was 3 days (range 2 to 8 days). Investigators' assessment following 6 months of routine prophylaxis was rated excellent in all 9 subjects; excellent was defined as 'no minor or major bleeds occurred during the study period' or 'lower frequency of bleeds than expected, given subject's medical/treatment history'. In addition, 22 infusions were given to treat a bleed, equivalent to 2.1 bleeds per subject per year. One subject had three episodes of epistaxis and the other bleeds were due to trauma or menorrhagia. All bleeds were treated with a single infusion; the median and mean doses per subject were both 31.7 IU/kg (range 24.6 to 38.8 IU/kg) and all recorded efficacy ratings were categorized as 'excellent' i.e. Overt bleed: bleeding stopped within 12 hours with a single dose; Menorrhagic bleed: no additional doses required; Covert bleeds: there were none in this study.
The safety and efficacy of COAGADEX for perioperative management was evaluated in five subjects aged 14 to 59 years with mild (n=2), moderate (n=1), and severe (n=2) disease, who underwent a total of seven surgical procedures.
For all surgical procedures, COAGADEX was assessed as excellent (no post-operative bleeding, no requirement of blood transfusions, and blood loss was no more than 'as expected') in controlling blood loss during and after surgery. For major surgeries, a median of 13 infusions (range 2 to 15 infusions) and a median cumulative dose of 181 IU/kg (range 45 to 210 IU/kg) were required to maintain hemostasis. For minor surgeries, a median of 2.5 infusions (range 1 to 4 infusions) and a median cumulative dose of 89 IU/kg (range 51 to 127 IU/kg) were required to maintain hemostasis.
One subject had insertion of a central venous access device (Portacath) and was given 6 infusions of COAGADEX during 5 days, a total of 2,750 IU (27 IU/kg); there were no bleeding complications or safety concerns.

This Patient Information leaflet summarizes important information about COAGADEX. Please read it carefully before using COAGADEX and each time you get a refill, as there may be new information. This Patient Information does not take the place of talking with your healthcare provider about your medical condition or treatment, and it does not include all of the important information about COAGADEX. If you have any questions about COAGADEX after reading this information, ask your healthcare provider.
What is the most important information I need to know about COAGADEX?
Do not attempt to do an infusion yourself unless you have been taught how by your healthcare provider or hemophilia center.
You must carefully follow your healthcare provider's instructions regarding the dose and schedule for infusing COAGADEX so that your treatment will work best for you.
What is COAGADEX?
COAGADEX is a medicine given as an injection into the vein to replace the clotting factor that is missing in people with Factor X deficiency. Factor X deficiency is an inherited bleeding disorder that prevents blood from clotting normally.
COAGADEX is used to treat, control or reduce bleeding in patients with hereditary Factor X deficiency.
Your healthcare provider may give you COAGADEX when you have surgery.
Who should not use COAGADEX?
You should not use COAGADEX if you are allergic (hypersensitive) to any of the ingredients in COAGADEX.
Tell your healthcare provider if you are pregnant or breast-feeding because COAGADEX may not be right for you.
What should I tell my healthcare provider before I use COAGADEX?
You should tell your healthcare provider if you:
How should I use COAGADEX?
You get COAGADEX as an infusion into your vein.
You may infuse COAGADEX at a hemophilia treatment center, at your healthcare provider's office or in your home. You should be trained on how to do infusions by your healthcare provider or hemophilia treatment center. Many people with coagulation factor deficiencies learn to infuse their treatment by themselves or with the help of a family member or caregiver.
Your healthcare provider will tell you how much COAGADEX to use based on your weight, the severity of your Factor X deficiency, and where you are bleeding from.
You may need blood tests done after using COAGADEX to be sure that the level of Factor X in your blood is high enough to clot your blood.
Call your healthcare provider right away if your bleeding does not stop after using COAGADEX.
What are the possible side-effects of COAGADEX?
You can have an allergic reaction to COAGADEX.
Stop treatment and call your healthcare provider right away if you have any of the following symptoms: difficulty breathing, chest tightness, swelling of the face, rash or hives.
Common side effects of COAGADEX are infusion site redness, infusion site pain, tiredness, and back pain.
Your body can also make antibodies, called "inhibitors," against COAGADEX, which may stop COAGADEX from working properly. Your healthcare provider may give you blood tests to check for inhibitors.
These are not all of the possible side effects of COAGADEX. Tell your healthcare provider about any side effects that bother you or do not go away.
What are the COAGADEX dosage strengths?
COAGADEX is packaged with a suitable volume (2.5 mL or 5 mL) of Sterile Water for Injection, and one Mix2Vial transfer device.
COAGADEX comes in two different dosage strengths:
Approximately 250 International Units (IU) – to be reconstituted with 2.5 mL of sterile water.
Approximately 500 International Units (IU) - to be reconstituted with 5 mL of sterile water.
The actual strength will be printed on the vial label and on the box. Once dissolved, the concentrations in these two vials will be the same, 100 IU per mL.
Always check the actual dosage printed on the label to make sure you are using the vial size prescribed by your healthcare provider.
Always check the expiration date printed on the box. Do not use the product after the expiration date printed on the box.
How do I store COAGADEX?
Keep COAGADEX in its original package to protect it from light.
Store COAGADEX in a refrigerator (not below 36°F [2°C]) or at room temperature (not to exceed 86°F [30°C]). Do not freeze.
What else should I know about COAGADEX?
Medicines are sometimes prescribed for purposes other than those listed here. Do not use COAGADEX for a condition for which it is not prescribed. Do not share COAGADEX with other people, even if they have the same symptoms or condition that you have.
