Octaplas, Pooled Plasma (Human)
Solvent/Detergent Treated Solution for Intravenous Infusion
Octaplas is a sterile, pyrogen free, frozen solution of solvent/detergent (S/D) treated pooled human plasma.
The active ingredient comprises plasma proteins such as albumin, immunoglobulins, other globulins, coagulation factors, complement proteins and protease inhibitors. The content and distribution of plasma proteins in Octaplas are comparable to reference ranges for healthy blood donors, except for Protein S and alpha2-antiplasmin. Within a mean total protein content of 57 mg/mL, albumin comprises ~50% and immunoglobulin classes G, A, and M comprise ~12%, ~3%, and ~1%, respectively. Protein S and alpha2-antiplasmin, which are labile to S/D treatment, are controlled to ensure levels in the final product of ≥ 0.4 International Units (IU) per mL. Plasma lipids and lipoproteins are reduced due to S/D treatment and subsequent oil and solid phase extraction.
Composition of Octaplas
| Component | Ouantity per 200 mL dose |
| Human plasma proteins | 9.0 - 14.0 g |
| Sodium citrate dihydrate | 0.88 - 1.48 g |
| Sodium dihydrogen-phosphate dihydrate | 0.06 - 0.24 g |
| Glycine | 0.80 - 1.20 g |
Octaplas is manufactured from human plasma collected in US licensed plasma donation centers. All plasma donations are tested for viral markers in compliance with US regulation. In addition, the manufacturing plasma pool may not contain a titer of human Parvovirus B19 DNA exceeding 10.0 IU per microliter and must have a negative result in a test for human Hepatitis E Virus (HEV) RNA by NAT PCR with a sensitivity of ≤ 2.5 log10 IU/mL.
Each lot of Octaplas is manufactured from pooled plasma of a single AB0 blood group (A, B, AB, or 0). The manufacturing plasma pool is limited to 390 kg comprising 630-1,520 individual donors. Frozen plasma units are thawed and pooled. Sodium dihydrogen phosphate dihydrate is added as a buffer against increase in pH due to loss of CO2. After filtration through a 1 μm pore size membrane, the plasma pool is treated with S/D reagents [1% tri(n-butyl) phosphate (TNBP) and 1% octoxynol for 1-1.5 hours at +30°C (86°F)] to inactivate enveloped viruses. The S/D reagents are removed by sequential oil and solid phase extraction procedures. Glycine is added to adjust the osmolality. Plasma with glycine is applied to a column filled with affinity ligand resin intended for selective binding of prion protein (PrPSc). The effectiveness of this step in removal of prion infectivity from the product has not been established. After sterile filtration, the product is filled into sterile polyvinyl chloride blood bags, labeled, deep-frozen and stored at a temperature of ≤ -18°C (-0.4°F). The finished product is tested for coagulation factors II, V, VII, VIII, IX, X and XI, Protein C, Protein S, alpha2-antiplasmin (also known as Plasmin Inhibitor), fibrinogen and ADAMTS13.
The S/D treatment step has been validated to effectively inactivate relevant pathogenic and model enveloped viruses as summarized in Table 1.

Serious adverse reactions seen in clinical trials were anaphylactic shock, citrate toxicity and severe hypotension.
The most common adverse reactions observed in ≥ 1% of subjects included pruritis, urticaria, nausea, headache, and paresthesia.
Because 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 trials of another drug and may not reflect the rates observed in clinical practice.
Adverse reactions observed in clinical trials derive from 9 clinical trials. The mean dose administered ranged from 6 to 15 milliliters/kg body weight; when used in plasma exchange the dose was between 15 to 75 milliliters/kg. Two of the studies were conducted in healthy volunteers (n=90).
In total, 359 subjects received about 600 transfusion episodes in these trials
The following table shows the adverse reactions observed in ≥ 1% of subjects in order of severity:
Headache, paresthesia
Nausea
Pruritis, urticaria
Because post-marketing reporting of adverse reactions is voluntary and from a population of uncertain size, it is not always possible to reliably estimate the frequency of these reactions or establish a causal relationship to product exposure.
Hyperfibrinolysis
Hypersensitivity reactions including anaphylactoid and allergic type of reactions
Alkalosis
Cardiac arrest, circulatory overload, thromboembolism, tachycardia
Respiratory arrest or failure, bronchospasm, pulmonary edema, dyspnea, tachypnoea
Abdominal pain, vomiting
Rash, erythema
Fever and/or chills, chest discomfort or pain
Seroconversions (passive transfer of antibodies)
Citrate toxicity
Do not inject drugs containing calcium in the same intravenous line with Octaplas because precipitants may block the line.
Included as part of the PRECAUTIONS section.
Transfusion reactions can occur with AB0 blood group mismatches. Administration of Octaplas must be based on ABO-blood group compatibility.
High infusion rates can induce hypervolemia with consequent pulmonary edema or cardiac failure. Monitor patients for signs and symptoms of pulmonary edema or cardiac failure and institute appropriate management.
Excessive bleeding due to hyperfibrinolysis can occur due to low levels of alpha2-antiplasmin (also named plasmin inhibitor). Monitor for signs of excessive bleeding in patients undergoing liver transplantation.
Thrombosis can occur due to low levels of Protein S. Monitor for signs and symptoms of thrombosis in patients at risk.
Citrate toxicity can occur with volumes exceeding one milliliter of Octaplas per kg per minute. The infusion rate should not exceed 0.020-0.025 mmol citrate per kilogram per minute (i.e., less than one milliliter Octaplas per kg per minute). Symptoms attributable to citrate toxicity (hypocalcaemia) include e.g., fatigue, paresthesia and muscle spasms, especially in patients with liver function disorders. Administer calcium gluconate intravenously into another vein in order to minimize citrate toxicity.
Because Octaplas 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 (CJD) agent. ALL infections suspected by a physician possibly to have been transmitted by this product should be reported by the physician or other healthcare provider to Octapharma [1-866-766-4860] or FDA at 1-800-FDA-1088 or www.fea.gov/medwatch.

No Information provided
Do not use Octaplas in patients with:
Octaplas replaces human plasma proteins.
Coagulation factor activities in the final product are controlled to obtain levels within the range of normal human plasma. Protein S and alpha2-antiplasmin, which are labile to S/D treatment, are controlled to ensure levels in the final product of ≥ 0.4 International Units (IU) per mL.
The Octaplas predecessor product was studied in liver disease, liver transplantation, cardiac surgery and TTP.
An open-label parallel group study was performed in surgical patients who were allocated to receive either a single infusion of Octaplas (n=20) or no plasma treatment (n=26) during open-heart surgery.10 A historical control group of patients having received standard single-donor FFP (n=20) was used to compare the efficacy and safety. The average dose of Octaplas was 700 mL (range 200 to 3400 mL), compared with 1012 mL (range 500 to 4000 mL) for standard FFP. The choice of plasma product (Octaplas or FFP) did not appear to influence the postoperative course with respect to volume of postoperative bleeding, the need for reoperation secondary to bleeding, or the length of the postoperative hospital stay. This study was not powered to detect any difference in efficacy.
A prospective, single-blind, randomized study was designed to investigate the safety and efficacy of Octaplas compared with standard FFP in adult patients with coagulopathies due to liver disease (LD) or liver transplantation (LTX), or for the management of newly diagnosed thrombotic thrombocytopenic purpura (TTP).11 -13 In total, 55 patients were included in the study. Three patients were suffering from TTP and all received Octaplas. Of the 24 patients with LD, 11 were treated with Octaplas, and out of the 28 LTX patients, 13 received Octaplas. Within the LD and the LTX groups, patients were comparable in all clinical aspects and in the dose of plasma given. There were no relevant changes in any of the coagulation factors, but protein C and fibrinogen improved considerably in both groups, accompanied by a corresponding improvement in partial thromboplastin time (PTT) levels 24 hours after infusion. Similar degrees of correction of prolonged international normalized ratio (INR) and PTT values were achieved with both Octaplas and FFP. All 3 patients with TTP attained platelet counts of >50x109/L by Day 10. This study was not powered to detect any difference in efficacy.
A prospective, non-randomized open-label study in intensive care patients was conducted in post-operative open heart surgery patients in the surgical intensive care unit who were in need of plasma transfusion for acute bleeding or for the risk of bleeding.14 There were a total of 67 patients, 36 who received Octaplas (600 mL) and 31 who received FFP (600 mL). Parameters measured included PT, PTT, free Protein S and plasmin inhibitor. Parameters were measured before treatment and 60 minutes after termination of plasma infusion. The decrease in PT and PTT, and the rise in free Protein S were similar between the two study arms. Plasmin inhibitor declined after Octaplas and remained unaffected by FFP. Clinical hemostasis evaluations were also similar between the two treatment regimens. This study was not powered to detect any difference in efficacy.
In a randomized, open-label, controlled study, 60 healthy adult volunteers (mean age 32.6±9.1 years) received after a standard plasmapheresis (PPh) of 600 mL plasma, an administration of 1200 mL of Octaplas or the predecessor product in a cross-over design. Coagulation factors (FI, FII, FV, FVII, FVIII, FIX, FX, and FXI) and hemostatic parameters (aPTT, PT and protein C) were assessed post-infusion at 15 minutes, 2 hours and 24 hours. The primary analysis was to demonstrate equivalence for recoveries using a 10% margin. All coagulation and hemostatic parameters met the equivalence criterion. To verify the assumption of improvement of plasmin inhibitor (PI) concentrations, a test for superiority was conducted. Statistically significant differences between treatments were found at 15 minutes (P=0.0012) and 2 hours (P=0.0190) post-transfusion for the per protocol population. Increased levels of PI post-infusion of Octaplas, as compared to the predecessor product may be attributable to the increased concentrations of PI.
