2 DOSAGE AND ADMINISTRATION
For intravenous administration only.
2.1 Dose
- Initiate treatment with CEPROTIN under the supervision of a physician experienced in replacement therapy with coagulation factors/inhibitors where monitoring of protein C activity is feasible.
- The dose, administration frequency, and duration of treatment with CEPROTIN depends on the severity of the protein C deficiency, the patient's age, the clinical condition of the patient, and the patient's plasma level of protein C.
- Adjust the dose regimen according to the pharmacokinetic profile for each individual patient. [See DOSAGE AND ADMINISTRATION: Protein C Activity Monitoring].
Table 1 provides the CEPROTIN dosing schedule for acute episodes, short-term prophylaxis and long-term prophylaxis.
Table 1: CEPROTIN Dosing Schedule for Acute Episodes, Short-term Prophylaxis and Long-term Prophylaxis* Initial Dose† Subsequent 3 Doses† Maintenance Dose† NA = Not applicable; Q = every. Acute Episode / Short-term Prophylaxis‡ 100-120 IU/kg 60 - 80 IU/kg
Q 6 hours45 - 60 IU/kg
Q 6 or 12 hoursLong-term Prophylaxis NA NA 45 - 60 IU/kg
Q 12 hours- Determine protein C recovery and half-life with an initial dose of 100-120 IU/kg in patients receiving treatment for acute episodes and short-term prophylaxis.
- Adjust the dose to maintain a target peak protein C activity of 100 %.
- Continue the patient on the same dose after resolution of the acute episode to maintain trough protein C activity level above 25% for the duration of treatment.
- Patients receiving prophylactic administration of CEPROTIN may warrant higher peak protein C activity levels in situations of an increased risk of thrombosis (such as infection, trauma, or surgical intervention). Therefore it is recommended to maintain trough protein C activity levels above 25%.
- These dosing guidelines are also recommended for neonatal and pediatric patients [See USE IN SPECIFIC POPULATIONS: Pediatric Use (8.4) and CLINICAL PHARMACOLOGY: Pharmacokinetics (12.3)].
Protein C Activity Monitoring
- Determine the patient's protein C plasma level before and during treatment with CEPROTIN by measuring protein C activity using a chromogenic assay.Certain clinical conditions, such as acute thrombosis, purpura fulminans, and skin necrosis, may shorten the half-life of CEPROTIN. See CLINICAL PHARMACOLOGY: Pharmacokinetics (12.3). In case of an acute thrombotic event, immediately measure protein C activity before the next injection until the patient is stable and monitor the protein C levels to maintain the trough protein C level above 25%.
- Patients treated during the acute phase of their disease may display much lower increases in protein C activity. In addition to protein C activity measurement, check the coagulation parameters also;however, data were insufficient to establish correlation between protein C activity levels and coagulation parameters in clinical trials.
Initiation of Vitamin K Antagonists
- In patients starting treatment with oral anticoagulants belonging to the class of vitamin K antagonists, a transient hypercoagulable state may arise before the desired anticoagulant effect becomes apparent. This transient effect may be because protein C, a vitamin K-dependent plasma protein, has a shorter half-life than most of the vitamin K-dependent proteins (i.e., Factor II, IX, and X).
- In the initial phase of treatment, the protein C activity is more rapidly suppressed than that of the procoagulant factors. For this reason, if the patient switched to oral anticoagulants, they must continue protein C replacement until stable anticoagulation is obtained. Although warfarin-induced skin necrosis can occur in any patient during the initiation of treatment with oral anticoagulant therapy, individuals with severe congenital protein C deficiency are particularly at risk.
- During the initiation of oral anticoagulant therapy, it is advisable to start with a low dose of the anticoagulant and adjust this incrementally, rather than use a standard loading dose of the anticoagulant.
2.2 Preparation
Reconstitution: Use Aseptic Technique
- Bring the CEPROTIN (powder) and Sterile Water for Injection, USP (diluent) to room temperature.
- Remove caps from the CEPROTIN and diluent vials.
- Cleanse stoppers with germicidal solution, and allow them to dry before use.
- Remove protective covering from one end of the double-ended transfer needle and insert the exposed needle through the center of the diluent vial stopper.
- Remove protective covering from the other end of the double-ended transfer needle. Invert diluent vial over the upright CEPROTIN vial; then rapidly insert the free end of the needle through the CEPROTIN vial stopper at its center. The vacuum in the vial will draw in the diluent. If there is no vacuum in the vial, do not use the product, and contact Takeda Pharmaceuticals Customer Service at 1-877-TAKEDA-7 (1-877-825-3327).
- Disconnect the two vials by removing the needle from the diluent vial stopper. Then, remove the transfer needle from the CEPROTIN vial. Gently swirl the vial until all powder is dissolved. Be sure that CEPROTIN is completely dissolved; otherwise, active materials will be removed by the filter needle.
2.3 Administration
Administration: Use Aseptic Technique
Visually inspect CEPROTIN for particulate matter and discoloration before administration.
After reconstitution, the solution should be colorless to slightly yellowish and clear to slightly opalescent, and free of visible particles. Do not use the solution if it does not meet these criteria. Administer CEPROTIN at room temperature not more than 3 hours after reconstitution.
- Attach the filter needle to a sterile, disposable syringe and draw back the plunger to admit air into the syringe.
- Insert the filter needle into the vial of reconstituted CEPROTIN.
- Inject air into the vial and then withdraw the reconstituted CEPROTIN into the syringe.
- Remove and discard the filter needle in a hard-walled Sharps container for proper disposal. Use filter needles to filter the contents of a single vial of CEPROTIN only.
- Attach a suitable needle or infusion set with winged adapter, and inject intravenously as instructed below under Administration by infusion.
Record the name and batch number of the product every time CEPROTIN is administered to a patient.

5 WARNINGS AND PRECAUTIONS
5.1 Hypersensitivity
CEPROTIN may contain traces of mouse protein and/or heparin as a result of the manufacturing process. Allergic reactions to mouse protein and/or heparin cannot be ruled out. If symptoms of hypersensitivity/allergic reaction occur, discontinue the injection/infusion. In case of anaphylactic shock, the current medical standards for treatment are to be observed.
5.2 Transmissible Infectious Agents
Because CEPROTIN is made from human plasma, 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 agent.
All infections suspected by a physician to have been possibly transmitted by this product should be reported by the physician or other healthcare provider to Takeda Pharmaceuticals at 1-877-TAKEDA-7 (1-877-825-3327). Discuss the risks and benefits of this product with your patient.
5.3 Bleeding Episodes
Several bleeding episodes have been observed in clinical studies. Concurrent anticoagulant medication may have been responsible for these bleeding episodes. However, it cannot be completely ruled out that the administration of CEPROTIN further contributed to these bleeding events.
Simultaneous administration of CEPROTIN and tissue plasminogen activator (tPA) may further increase the risk of bleeding from tPA.
5.4 Heparin-induced Thrombocytopenia (HIT)
CEPROTIN contains trace amounts of heparin which may lead to Heparin-induced Thrombocytopenia, which can be associated with a rapid decrease of the number of thrombocytes. Identifying HIT is complicated because these symptoms may already be present in acute phase patients with severe congenital protein C deficiency. Determine the platelet count immediately and consider discontinuation of CEPROTIN.
-
6 ADVERSE REACTIONS
The common adverse reactions related to CEPROTIN treatment observed were the following hypersensitivity or allergic reactions: lightheadedness and itching and rash.
6.1 Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in one clinical trial of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
The safety profile of CEPROTIN was based on 121 patients from clinical studies and compassionate use in severe congenital Protein C deficiency. Duration of exposure ranged from 1 day to 8 years. One patient experienced hypersensitivity/allergic reactions (itching and rash) and lightheadedness which were determined by the investigator to be related to CEPROTIN.
No inhibiting antibodies to CEPROTIN have been observed in clinical studies. However, the potential for developing antibodies cannot be ruled out.
6.2 Postmarketing Experience
The following adverse reactions have been identified during postapproval use of CEPROTIN. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Psychiatric Disorders: Restlessness
Skin and Subcutaneous Tissue Disorders: Hyperhydrosis
General Disorders and Administration Site Conditions: Injection Site Reaction

8 USE IN SPECIFIC POPULATIONS
8.1 Pregnancy
Risk Summary
There are no data with CEPROTIN use in pregnant women to inform a drug-associated risk. Animal reproduction studies have not been conducted with CEPROTIN. It is also not known whether CEPROTIN can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity.
CEPROTIN has not been studied for use during labor and delivery.
In the U.S. general population, the estimated background risk of major birth defects and miscarriages in clinically recognized pregnancies is 2-4% and 15-20%, respectively, regardless of drug exposure.
8.2 Lactation
Risk Summary
There is no information regarding the presence of CEPROTIN in human milk, the effect on the breastfed infant, or the effects on milk production. CEPROTIN has not been studied for use in nursing mothers.
The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for CEPROTIN and any potential adverse effects on the breastfed child from CEPROTIN or from the underlying maternal condition.
8.4 Pediatric Use
Neonatal and pediatric subjects were enrolled during the prospective and retrospective studies described in CLINICAL STUDIES (14). Of the 18 subjects enrolled during the prospective study, 1 was newborn, 3 were between 28 days and 23 months, 9 were between 2 and 11 years, 1 was between 12 and 16 years, and 4 were older than 16 years. Of the 11 subjects enrolled and treated during the retrospective study, 9 were between 2 and 11 years, and 2 were older than 16 years [see CLINICAL STUDIES (14)].

11 DESCRIPTION
CEPROTIN [Protein C Concentrate (Human)] is manufactured from human plasma purified by a combination of filtration and chromatographic procedures, including a column of immobilized mouse monoclonal antibodies on gel beads [See WARNINGS AND PRECAUTIONS: Transmissible Infectious Agents (5.2)].
The manufacturing process for CEPROTIN includes processing steps designed to reduce the risk of viral transmission. 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, using the following enveloped and non-enveloped viruses: Human Immunodeficiency Virus Type 1 (HIV-1), Bovine Viral Diarrhea Virus (BVDV ), Tick-Borne Encephalitis Virus (TBEV), Pseudorabies Virus (PRV), Hepatitis A Virus (HAV) and Mice Minute Virus (MMV). Virus reduction steps consist of detergent treatment (Polysorbate 80, P80), heat inactivation (Vapor Heating) and immunoaffinity chromatography (IAX).
Virus clearance studies for CEPROTIN have demonstrated that the process provides for a robust overall virus clearance capacity. A summary of log10 virus reduction factors per virus and manufacturing step is presented in Table 2.

12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
Protein C is the precursor of a vitamin K-dependent anticoagulant glycoprotein (serine protease) that is synthesized in the liver [See DOSAGE AND ADMINISTRATION: Dose (2.1) Initiation of Vitamin K Antagonists]. It is converted by the thrombin/thrombomodulin-complex on the endothelial cell surface to activated Protein C (APC). APC is a serine protease with potent anticoagulant effects, especially in the presence of its cofactor protein S. APC exerts its effect by the inactivation of the activated forms of factors V and VIII, which leads to a decrease in thrombin formation. APC has also been shown to have profibrinolytic effects.
The Protein C pathway provides a natural mechanism for control of the coagulation system and prevention of excessive procoagulant responses to activating stimuli. A complete absence of protein C is not compatible with life. A severe deficiency of this anticoagulant protein causes a defect in the control mechanism and leads to unchecked coagulation activation, resulting in thrombin generation and intravascular clot formation with thrombosis.
12.2 Pharmacodynamics
In clinical studies, the intravenous administration of CEPROTIN demonstrated a temporary increase, within approximately half an hour of administration, in plasma levels of APC. Replacement of protein C in protein C-deficient patients is expected to control or, if given prophylactically, to prevent thrombotic complications.
12.3 Pharmacokinetics
Table 3 provides pharmacokinetic results for asymptomatic and symptomatic subjects with protein C deficiency.
Table 3: Pharmacokinetics of CEPROTIN in Subjects with Severe Congenital Protein C Deficiency PK parameter N Median 95% CI for median Min Max Cmax = Maximum concentration after infusion; T max = Time at maximum concentration; AUC 0-Infinity = Area under the curve from 0 to infinity; MRT = Mean residence time; and Incremental recovery = Maximum increase in Protein C concentration following infusion divided by dose Cmax [IU/dL] 21 110 106 to 127 40 141 Tmax [h] 21 0.50 0.50 to 1.05 0.17 1.33 Incremental recovery [(IU/dL)/(IU/kg)] 21 1.42 1.32 to 1.59 0.50 1.76 Initial half-life [h] 21 7.8 5.4 to 9.3 3.0 36.1 Terminal half-life [h] 21 9.9 7.0 to 12.4 4.4 15.8 Half-life by the non-compartmental approach [h] 21 9.8 7.1 to 11.6 4.9 14.7 AUC0-Infinity [IU*h/dL] 21 1500 1289 to 1897 344 2437 MRT [h] 21 14.1 10.3 to 16.7 7.1 21.3 Clearance [dL/kg/h] 21 0.0533 0.0428 to 0.0792 0.0328 0.2324 Volume of distribution at steady state [dL/kg] 21 0.74 0.70 to 0.89 0.44 1.65 The protein C plasma activity was measured by chromogenic and/or clotting assay. The maximum plasma concentrations (Cmax) and area under the plasma concentration-time curve (AUC) appeared to increase dose-linearly between 40 and 80 IU/kg. The median incremental recovery was 1.42 [(IU/dL)/(IU/kg)] after intravenous administration of CEPROTIN. The median half-lives, based on non-compartmental method, ranged from 4.9 to 14.7 hours, with a median of 9.8 hours. In patients with acute thrombosis, both the increase in protein C plasma levels as well as half-life may be considerably reduced. No formal study or analysis has been performed to evaluate the effect of covariates such as race and gender on the pharmacokinetics of CEPROTIN.
The pharmacokinetic profile in pediatric patients has not been formally assessed. Limited data suggest that the pharmacokinetics of CEPROTIN may be different between very young children and adults. The systemic exposure (Cmax and AUC) may be considerably reduced due to a faster clearance, a larger volume of distribution, and/or a shorter half-life of protein C in very young children than in older subjects. Consider this fact when a dosing regimen for children is determined. Doses should be individualized based upon protein C activity levels [See DOSAGE AND ADMINISTRATION: Dose (2.1) Protein C Activity Monitoring].

13 NONCLINICAL TOXICOLOGY
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
Protein C contained in CEPROTIN is a normal constituent of human plasma and acts like endogenous protein C. Studies in heterologous species to evaluate carcinogenicity, reproductive toxicology and developmental toxicology have not been performed.
CEPROTIN has not demonstrated mutagenic potential in the Salmonella Thyphimurium reverse mutation assay (Ames test).
13.2 Animal Toxicology and/or Pharmacology
Safety Pharmacology:
Cardio-respiratory studies performed in dogs evaluating mean arterial pressure, cardiac output, systemic vascular resistance, heart rate, QT interval changes, pulmonary artery pressure, respiratory rate and respiratory minute volume demonstrated no adverse effects at a maximum dose of 500 IU/kg. Anaphylactoid reactions as determined by measurement of bronchospastic activity in guinea pigs demonstrated no adverse effects at the maximum dose of 300 IU/kg. Thrombogenic potential was evaluated in rabbits using the Wessler stasis model and demonstrated no adverse effects at 200 IU/kg. Overall, safety pharmacology studies evaluating cardio-respiratory function, acute dose anaphylactoid potential and thrombogenicity demonstrated no adverse effects in a range of doses from 1.6 to 4.2 times the maximum single human dosage per kilogram body weight.
Acute Dose Toxicity:
Toxicity testing in rats and mice following single dosing of 2000 IU/kg or 1500 IU/kg, respectively, demonstrated no adverse clinical effects or gross pathology at 14 days post dosing.
Repeated Dose Toxicity:
Studies were not conducted to evaluate repeated-dose toxicity in animals. Prior experience with CEPROTIN has suggested immunogenic response in heterologous species following repeated dosing of this human derived protein. Thus, the long-term toxicity potential of CEPROTIN following repeated dosing in animals is unknown.
Local Tolerance Testing:
Investigation of route of injection tolerance demonstrated that CEPROTIN did not result in any local reactions after intravenous, intra-arterial injections of 500 IU/kg (5 mL) and paravenous injections of 100 IU/kg (1 mL) in rabbits.
Citrate Toxicity:
CEPROTIN contains 4.4 mg of Trisodium Citrate Dihydrate (TCD) per mL of reconstituted product. Studies in mice evaluating 1000 IU vials reconstituted with 10 mL vehicle followed by dosing at 30 mL/kg (132 mg/kg TCD) and 60 mL/kg (264 mg/kg TCD) resulted in signs of citrate toxicity (dyspnea, slowed movement, hemoperitoneum, lung and thymus hemorrhage and renal pelvis dilation).

14 CLINICAL STUDIES
In a multi-center, open-label, non-randomized study in 3 parts, the safety and efficacy of CEPROTIN was evaluated in subjects with severe congenital protein C deficiency for the (on-demand) treatment of acute thrombotic episodes, such as purpura fulminans (PF), warfarin-induced skin necrosis (WISN) and other thromboembolic events, and for short-term or long-term prophylaxis. Eighteen subjects (9 male and 9 female), ages ranging from 0 (newborn) to 25.7 years participated in this study.
The clinical endpoint of the study was to assess whether episodes of PF and/or other thromboembolic events were treated effectively, effectively with complications, or not treated effectively. Table 4 provides a comparison of the primary efficacy ratings of PF from the study to the historical controls. Inadequate data is available for treatment of WISN.
Table 4: Comparison of Primary Efficacy Ratings of Episodes of Purpura Fulminans in the Protein C Concentrate (Human) Study of Historical Controls Protein C Concentrate (Human) Historical Controls Episode Type Primary Efficacy Rating N % N % Purpura Fulminans Effective 17 94.4 11 52.4 Effective with Complication 1 5.6 7 33.3 Not Effective 0 0.0 3 14.3 Total 18 100 21 100 Of 18 episodes of PF (6 severe, 11 moderate, 1 mild) treated with CEPROTIN for the primary efficacy rating, 17 (94.4%) were rated as effective, and 1 (5.6%) was rated as effective with complications; none (0%) were rated not effective. 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.
Table 5 provides a summary of the secondary treatment ratings for treatment of skin lesions and other thrombotic episodes from part one of the study.

Four (80%) of the 5 episodes of venous thrombosis had treatment ratings of excellent, while 1 (20%) was rated as good.
CEPROTIN was also demonstrated to be effective in reducing the size and number of skin lesions. Non-necrotic skin lesions healed over a maximum 12-day (median 4-day) period and necrotic skin lesions healed over a maximum 52-day (median 11-day) period of CEPROTIN treatment, as shown in Table 6.

PATIENT INFORMATION
CEPROTIN [Protein C Concentrate (Human)]
Pronounced: see PRO tenPlease 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.
Use this leaflet only after you have received instructions from your doctor. If you have any questions after reading this leaflet, ask your doctor or pharmacist.
1. What is CEPROTIN and what is it used for?
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).
2. 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.
3. Who should not use CEPROTIN?
Do not use CEPROTIN unless your doctor confirms that you have severe congenital Protein C deficiency.
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 heparin, 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.
Low Sodium Diet/Kidney Impairment:
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 Breastfeeding:
Inform your doctor if you are pregnant or breastfeeding. Your doctor will decide if CEPROTIN may be used during pregnancy and/or breastfeeding.
Tell your doctor about all the medicines you are taking, including prescription and nonprescription medicines, vitamins, and herbal supplements. Tell your doctor if you are on a special diet.
4. What is the most important information I need to know about CEPROTIN?
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, stop the treatment and contact your doctor. If you experience a severe allergic reaction, including difficulty breathing and (near) fainting, seek emergency treatment.
You could get an infectious disease since this drug product is made from human plasma. However, there are steps in collecting 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.
5. What are the possible side effects of CEPROTIN?
Like all medicines, CEPROTIN can cause side effects, although not everyone gets them.
The common side effects to CEPROTIN observed in clinical trials were hypersensitivity or allergic reactions: lightheadedness itching, and rash.
There have also been individual reports, after the drug was marketed, of restlessness, increased sweating, and injection site reaction.
If you develop any side effects, including any not listed in this leaflet, please contact your doctor.
6. How do I use CEPROTIN?
CEPROTIN is given by intravenous administration (infusion into a vein). It is given to you under the close supervision of your doctor who is experienced in replacement therapy of coagulation factors/inhibitors and where monitoring of protein C activity is possible. Your dosage will vary depending upon your condition, your age, and your body weight. Your doctor may require that you have blood taken to help determine the dose of CEPROTIN that you should get. See the following Instructions for Use.
7. How do I store CEPROTIN?
Store CEPROTIN in powder form, without the diluent (Sterile Water for Injection) added. Store CEPROTIN in the refrigerator at 2°C to 8°C (36°F to 46°F). Store the vial in the original carton to protect it from light. Do not freeze to prevent damage to the diluent vial.
Do not use CEPROTIN beyond the expiration date printed on the CEPROTIN vial.

Do not attempt to self-infuse unless you have been taught how by your doctor.
- Prepare a clean surface and gather all the materials you will need for the infusion. You will need to gather exam gloves (optional), alcohol swabs (or other suitable solution suggested by your doctor), a winged infusion set, and a tourniquet, as these are not provided with your package of CEPROTIN.
- Check the expiration date on the CEPROTIN vial. Do not use CEPROTIN after the expiration date.
- Let the vial of CEPROTIN and the vial of Sterile Water for Injection, USP (diluent) warm up to room temperature.
- Wash your hands and put on clean exam gloves (optional).
