Generic Name: Protein C Concentrate (Human)
Date of Approval: March 30, 2007
Company: Baxter Healthcare Corporation
Treatment for: Severe Congenital Protein C Deficiency
Ceprotin approved by FDAThe U.S. Food and Drug Administration (FDA) has approved Ceprotin [Protein C Concentrate (Human)], a plasma-derived Protein C concentrate for use as replacement therapy in patients with life-threatening blood-clotting complications related to severe congenital Protein C deficiency.
Severe congenital Protein C deficiency results in a hypercoagulable state, meaning there is an abnormal tendency for blood clotting. This can cause severe, often life-threatening blood clots in small blood vessels, which if left untreated could result in blindness, severe brain damage, multi-organ failure and death. The disease manifests in children very early in life, often in utero or in the first few days of life. Incidence of severe congenital Protein C deficiency has been estimated to be one to two for every million births. Currently, there are fewer than 20 known cases of severe congenital Protein C deficiency in the United States. FDA has granted Ceprotin orphan drug status.
Ceprotin is the first FDA approved therapy for patients with severe congenital Protein C deficiency. It is indicated for patients with severe congenital Protein C deficiency for the prevention and treatment of venous thrombosis and purpura fulminans (PF) (a severe skin and systematic blood clotting disorder). Ceprotin is indicated as a replacement therapy for pediatric and adult patients.
Ceprotin Clinical Data
Ceprotin's approval is based on data from a pivotal multi-center, open- label, non-randomized, Phase II/III study, which evaluated the safety and efficacy of Ceprotin in subjects with severe congenital Protein C deficiency for the (on-demand) treatment of acute thrombotic episodes, such as PF, warfarin-induced skin necrosis (WISN), and other thromboembolic events, and for short-term or long-term prophylaxis. The study included 18 patients (nine male and nine female) ranging in age from newborn to 25.7 years. Ceprotin was demonstrated to be effective in 94 percent of the episodes of PF. In the remaining six percent of patients, the treatment was found "effective with complications" because they required a dosage adjustment. Inadequate data were available for the treatment of WISN.
When compared with the efficacy ratings for 21 episodes of PF (historical control group), subjects with severe congenital Protein C deficiency were more effectively treated with Ceprotin than those treated with modalities such as fresh frozen plasma or conventional anticoagulants. Ceprotin also demonstrated effectiveness in reducing the size and number of skin lesions in patients. Treatment with Ceprotin healed non-necrotic skin lesions after a median of four days, and necrotic skin lesions were healed after a median of 11 days.
Seven patients took Ceprotin as a preventive measure before surgery or anticoagulation therapy and had no associated blood clotting complications. Eight patients who were given Ceprotin as a long term preventive measure, again did not experience any blood clotting complications.
In the clinical development period, no serious adverse reactions related to Ceprotin were reported. The most common adverse reactions observed in clinical trials were rash, itching, and lightheadedness.
Ceprotin [Protein C Concentrate (Human)] is indicated for patients with severe congenital Protein C deficiency for the prevention and treatment of venous thrombosis and purpura fulminans. Ceprotin is indicated as a replacement therapy for pediatric and adult patients.
Important Safety Information
The most serious and common adverse reactions observed in clinical trials were rash, itching and lightheadedness.
The following adverse reactions have been identified during postapproval use of Ceprotin: hemothorax, hypotension, hyperhydrosis, fever and restlessness.
Patients on low sodium/renal impairment diet should be informed that the quantity of sodium in the maximum daily dose of Ceprotin exceeds 200mg.
Ceprotin contains trace amounts of heparin, which may lead to Heparin- induced Thrombocytopenia.
As with all plasma-derived therapeutics, the potential to transmit infectious agents (e.g. viruses) cannot be totally eliminated.

Ceprotin Patient Information
Protein C Concentrate (Human)
Please read this leaflet carefully before using Ceprotin [Protein C Concentrate (Human)]. This leaflet is based on the information provided to your doctor, and is a summary of the important information you need to know about your medicine for your severe congenital Protein C deficiency. This leaflet does not take the place of talking with your doctor and does not contain all of the information available about Ceprotin.
This leaflet should be used only after you have received instructions from your doctor. If you have any questions after reading this leaflet, ask your doctor or pharmacist.
What is Ceprotin?
The name of your medicine is Ceprotin, pronounced "see PRO ten".
Ceprotin contains Protein C, a natural protein that is made in the liver and is present in your blood. Protein C is a part of human plasma that regulates the blood clotting (coagulation) system and prevents abnormal clot formation (thrombosis). Plasma is the liquid part of human blood.
Ceprotin is used to treat patients with Severe Congenital Protein C Deficiency for the prevention and treatment of:
- venous thrombosis (blood clot in the vein), and
- purpura fulminans (blood spots, bruising and discoloring to skin as a result of clotting of small blood vessels in the skin).
How does Ceprotin work?
Ceprotin temporarily raises the levels of Protein C in the body. Protein C plays a major role in preventing your body from forming too many blood clots. Ceprotin is for those patients who either don't produce enough Protein C or whose Protein C doesn't work correctly. Ceprotin allows your body's blood clotting process to function properly.
Who should not use Ceprotin?
You should not use Ceprotin unless your doctor confirms that you have severe congenital Protein C deficiency.
You should tell your doctor about all your medical conditions.
Allergic to Mouse Protein or Heparin:
If you are known to have allergic-type reactions (rash, hives, itching, tightness of the chest, difficulty breathing, throat tightness, and low blood pressure) to mouse protein or to heparin, you should talk to your doctor before using this product. Ceprotin contains small amounts of heparin and/or mouse protein as a result of the manufacturing process. If such a reaction occurs, you should discuss this with your doctor and your doctor will decide the right treatment.
Low Sodium Diet/Kidney Impairment:
You should talk with your doctor before using Ceprotin if you are on a low sodium diet or have problems with your kidney, as the amount of sodium in the maximum daily dose of Ceprotin exceeds 200 mg.
Pregnancy or Breast-feeding:
You should inform your doctor if you are pregnant or breast-feeding. Your doctor will decide if Ceprotin may be used during pregnancy and/or breast-feeding.
Tell your doctor about all the medicines you are taking including prescription and nonprescription medicines, vitamins, and herbal supplements. You should also tell your doctor if you are on a special diet.
You could have an allergic reaction to Ceprotin. You should be aware of the early signs of allergic reactions. These include: rash, hives, itching, tightness of the chest, difficulty breathing, throat tightness, and low blood pressure. The signs and symptoms of low blood pressure can include a weak pulse, feeling lightheaded or dizzy when you stand, and possibly shortness of breath. If you experience any of these symptoms while being treated with Ceprotin, quickly stop the treatment and contact your doctor. If you experience a severe allergic reaction, including difficulty breathing and (near) fainting, you should quickly seek emergency treatment.
You could get an infectious disease since this drug product is made from human plasma. However, there are steps in the collection of the plasma and in the making of Ceprotin to lessen this possibility. For example, blood and plasma donors are screened for certain viral infections. There are also steps in the processing of the plasma that can inactivate or remove viruses.
You could get an infection with a virus called Human Parvovirus B19 (B19 Virus). Fetuses are at risk to the B19 Virus. Symptoms of B19 Virus infection include fever, drowsiness, chills and runny nose followed about two weeks later by a rash and joint pain. Pregnant women should discuss this risk with their doctor.
Although, there are steps during the making of Ceprotin to reduce the risk of getting Hepatitis A and B, your doctor may recommend that you be vaccinated against these viruses.
Ceprotin side effects
Like all medicines, Ceprotin can cause side effects, although not everyone gets them.
The most serious and common side effects to Ceprotin observed in clinical trials were allergic reactions (rash and itching) and lightheadedness.
There have also been individual reports, after the drug was marketed, of thoracic hematoma (bleeding into the chest), hypotension (very low blood pressure), fever, restlessness and increased sweating.
You could develop antibodies that can prevent Ceprotin from working properly and therefore reduce its effect. This has not been seen in clinical studies.
If you develop any side effects, including any not listed in this leaflet, please contact your doctor.
