1. What is Cluvot and what is it used for
What is Cluvot
Cluvot is a medicine that comes as a white powder and solvent. The reconstituted solution should be administered by intravenous injection.
Cluvot is human blood coagulation factor XIII (F XIII) produced from human plasma (the liquid part of the blood) and plays an important role in the process of haemostasis (stopping bleeding).
What is Cluvot used for
Cluvot is indicated for use in adults, children, and adolescents.
- for prophylactic treatment of congenital factor XIII deficiency and
- in perioperative management to treat bleeding during surgical procedures in patients with congenital factor XIII deficiency.
2. Important information before using Cluvot
This section of the package leaflet contains information that you should consider before starting treatment with Cluvot.
When not to use Cluvot:
Tell your doctor if you have an allergy to any medicine or food.
Warnings and precautions:
- the formation of inhibitors (antibodies that neutralize) is known as a complication of treatment and means that the treatment stops working. If bleeding is not controlled with Cluvot, you should inform your doctor immediately. You should be closely monitored for the development of inhibitors.
Your doctor should always weigh the benefits of treatment against the risk of complications.
Viral safety
When medicines are made from human blood or plasma, various measures are taken to prevent the transmission of infectious agents. These measures include:
- careful selection of blood and plasma donors to exclude the risk of transmitting infectious agents
- testing each donation and plasma pool for the presence of virus markers/infections.
- introducing steps in the manufacturing process that can inactivate or remove viruses.
Despite these measures, it cannot be completely excluded that the transmission of infectious agents cannot be completely excluded when administering a medicinal product derived from human blood or plasma. This risk also applies to unknown or newly discovered viruses and other infectious agents.
The measures taken are effective against enveloped viruses such as human immunodeficiency virus (HIV, the virus that causes AIDS), hepatitis B virus (HBV, which causes hepatitis B), and hepatitis C virus (HCV, which causes hepatitis C), as well as non-enveloped viruses such as hepatitis A virus (HAV, which causes hepatitis A) and parvovirus B19.
For patients receiving repeated doses of products derived from human plasma, consideration should be given to vaccination against hepatitis A and B.
It is recommended that the date of administration, batch number, and administered volume be recorded in the patient's medical record each time Cluvot is administered.
Cluvot and other medicines
- Tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including those obtained without a prescription.
- No interactions between factor XIII concentrate and other medicinal products are known.
- Cluvot must not be mixed with other medicinal products, solvents, or diluents, except for those mentioned in section 6, and should be administered using separate infusion sets.
Pregnancy and breastfeeding
- If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
- Limited data on the clinical use of Cluvot in pregnancy do not indicate any negative effects on pregnancy and embryonic/foetal development. Cluvot may be used during pregnancy if necessary.
- The extent of transfer of Cluvot into human milk is unknown, but considering its high molecular mass, the likelihood of excretion into breast milk is very low, and due to its protein nature, absorption of intact molecules by the newborn is also unlikely. Therefore, Cluvot can be used during breastfeeding.
- No data are available on the effects of Cluvot on fertility.
Driving and using machines
No studies have been conducted on the effects on the ability to drive and use machines.
Important information about some of the ingredients of Cluvot

Information intended for healthcare professionals only: Dosage
1 ml is approximately equal to 62.5 IU, and 100 IU is equivalent to 1.6 ml.
Important:
The amount to be administered and the frequency of administration should always be adjusted according to the individual patient's clinical efficacy.
Dosage
Dosage should be individually tailored based on body weight, laboratory results, and the patient's clinical condition.
Routine dosing schedule for prophylaxis
Initial dose
- 40 international units (IU) per kilogram of body weight.
- The infusion rate should not exceed 4 ml per minute
Subsequent doses
- Dosage should be determined based on the current level of FXIII activity, and doses should be administered at 28-day intervals (4 weeks) to maintain a minimum FXIII activity level of approximately 5 to 20%.
- Recommended dose adjustment of +/- 5 IU/kg body weight should be calculated based on the minimum FXIII activity level as shown in Table 1 and the patient's clinical condition.
- Dose adjustment should be based on a specific, sensitive test used to determine FXIII levels. Examples of dose adjustment using the standard Berichrom activity test are presented in the following Table 1.
Table 1: Dose adjustment using the Berichrom activity test
Activity is expressed in units using the Berichrom activity test, referring to the current International Standard for Plasma Factor XIII. Therefore, one unit is equivalent to one International Unit.
Perioperative prophylaxis.
| Minimum FXIII activity level (%) | Dose adjustment |
| One minimum level <5% | Increase by 5 units/kg. |
| Minimum level 5% to 20% | No change |
| Two minimum levels > 20% | Decrease by 5 units/kg. |
| One minimum level > 25% | Decrease by 5 units/kg. |
After the last dose administered in routine prophylaxis, in case of a planned surgical procedure:
- Between 21 and 28 days after the last dose - a full dose should be administered to the patient immediately before surgery, and the next prophylactic dose should be administered 28 days later.
- Between 8 and 21 days after the last dose - an additional dose (full or partial) may be administered before surgery. The dose should be based on the patient's FXIII activity level, clinical condition, and should be adjusted according to the half-life of the medicinal product Cluvot.
- Within 7 days of the last dose - additional administration may not be necessary.
Dose adjustment may differ from the recommended dose and should be individually tailored based on FXIII activity level and the patient's clinical condition. All patients should be closely monitored during and after surgery.
In this regard, it is recommended to monitor the increase in FXIII activity level based on the FXIII test. In case of major surgical procedures and significant bleeding, the goal should be to achieve near-normal values (healthy individuals: 70%-140%).
Children and adolescents
Dosage and administration in children and adolescents are based on body weight and generally do not differ from the guidelines for adults. Dosage and/or administration frequency for each patient should always be adjusted based on clinical efficacy and FXIII activity level.
Elderly patients
Dosage and administration in elderly patients (> 65 years) have not been documented in clinical trials.
Method of administration
General instructions
The solution should be clear or slightly opalescent. After filtration/removal of the vial contents (see below), the reconstituted product before administration should be visually inspected; check for any contamination or change in color.
Do not use cloudy solutions or those that contain flakes or particles.
