7.2 million units of Octaplasma infused worldwide
in ~2.4 million patients over two decades
OctaplasmaTM History
• Octaplasma was first approved in Germany in 1992
• Has become the standard treatment for TTP/HUS patients
throughout most of Europe and the UK
• The clinical trial program comprised 1,385 patients
• Production facilities are based in Vienna (Austria) and
Stockholm (Sweden)
The Rational for Development of OctaplasmaTM
• Reduce the risk of pathogen transmission
• Transmission of human immunodeficiency virus (HIV)
• Post-tranfusion hepatitis caused by
– Hepatitis B / Hepatitis C virus
• Meet the need for a cell free, standardized, high
quality coagulation active plasma
• To reduce adverse events
• To improve the therapeutic accuracy of plasma treatment
Risks of Plasma Therapy
Fresh frozen plasma (FFP) transfusion plays a vital role in treatment of several specific
clinical situations, however, FFP transfusion is not without complications
Pathogen transmissions and
infections
• Parasites
• Bacteria
• Viruses (especially HIV, HBV, and HCV)
• Prions [e.g. variant Creutzfeldt-Jakob disease (vCJD)]
Immune-mediated transfusion
reactions
• Allergic reactions
• Anaphylactoid and anaphylactic reactions
• Transfusion-related acute lung injury (TRALI)
• Haemolysis (anti-AB0s IgM and IgG, irregular antibodies)
• Alloimmunisation (e.g. anti-D, anti-K, anti-HLA, anti-HNA)
Physicochemical reactions
• Transfusion-associated circulatory overload (TACO)/fluid
overload
• Reactions due to additives (e.g. citrate toxicity)

Transfusion Related Lung Injury (TRALI)
•
No confirmed cases of TRALI with Octaplasma in 20 years
•
The incidence of TRALI has been reduced, but is still reported in Canada
despite the introduction of male-only plasma
•
TRALI remains the leading cause of Transfusion related fatalities in North
America which is approximately 30% 1,2
•
TRALI is significantly under diagnosed and consequently under reported due
to the lack of awareness 3-5

OctaplasmaTM - Efficacy in TTP
Scully et al. (2007)
• 12 episodes were performed using CPP only; 21
episodes exclusively used OctaplasmaTM.
• No difference in the number of plasma exchange
procedures between groups
• 17 CPP episodes had to be changed to
OctaplasmaTM due to low age (n=1), severe
allergic reactions to CPP (n=12) or due to
refractory disease (n=4). This means that of
the 29 episodes that started with CPP, as
many as 12 (41%) had to be changed to
Octaplasma® due to severe allergic reactions.
• No significant thrombotic episodes, no
detectable viral transmissions, no cases of
TRALI

OctaplasmaTM reduces both infectious and noninfectious risks of transfusions
The overall reduction in transfusion complications (-94%)1
for Octaplasma® compared to FFP is similar to published
experience from Finland, -84%2 and Sweden, -85%3,
Austria -94.6%
With no confirmed case of TRALI in 20 years and the
significantly reduced risk for allergic reactions are major
advantages that Octaplasma® has over FFP.

SD Treatment of Octaplasma
TM
• Treatment with SD is widely used for ensuring the virus safety of plasma products.
• SD mixtures disrupt the lipid membrane of enveloped viruses. Once disrupted, the virus can no
longer bind to and infect cells.
• SD is gentle to plasma proteins
• SD treatment does not affect the final composition of OctaplasmaTM

Non-lipid Enveloped Viral Safety by
Immune Neutralization
• Immune antibodies in OctaplasmaTM neutralize viral particles and are of
importance in avoiding clinical disease with HAV and Parvovirus B19.
• The capacity to neutralize non-enveloped viruses in OctaplasmaTM by
immune antibodies is very high and thereby prevents transmission and
infections in the recipients.

Octaplasma - Efficacy in TTP
TM
Edel et al. (2010)
• Efficacy and tolerability of Octaplasma has been studied in TTP
• Overview: Retrospective analysis of 506 treatments (n=8) & 1999 L of
plasma used over course of treatment
• Efficacy parameters: Platelet count above 150 x 109 achieved;
ADAMTS13 inhibitory antibodies were partially or completely removed by
therapeutic plasma exchange
• AEs: Use of S/D was well tolerable with no AEs and no thrombotic events

allergic reactions per 100’000 bags
Answering TTP – Community Survey
• 82% of survey respondents cited at least 1 type of adverse reaction
during TTP treatment
“Counting down the bags of donor plasma is all you can do to wait for it to end.
You don't know if you will have an allergic reaction to the next bag and how
severe that reaction might be until it happens. Just cross your fingers and hope
you don't react.”
“Although the risk of contracting a disease from [FP] is supposed to be quite
low, the sheer volume of plasma I have received each time I have relapsed
increases the risk quite a bit, and that is always in the back of my mind. I do not
know the exact amount I have received but I am sure it is upwards of 150 units
per relapse (the last relapse lasted 3 months and was far more than that). A
safer product would make me feel a lot less stress.”

Efficacy in Single Factor Clotting Deficiency
Inbal et al.
■ Prospective and interventional study
■ A total of 11 patients, 8 with hereditary (2 FVII, 2 FX, 4 FXI deficiencies) and 3 with
acquired complex coagulopathies, were treated with Octaplas®
■ The amount of Octaplas® infused ranged between 6-12 ml/kg
■ In all the 11 patients Octaplas® was sufficient to prevent or stop bleeding
Santagostino et al.
■ An open-label multicenter trial of Octaplas® involving 17 patients with inherited
coagulation disorders (1 afibrinogenemia, 4 FV, 6 combined FV and FVIII, 1 FX and 5
FXI deficiencies)
■ Study evaluated the pharmacokinetics of the deficient factors and hemostatic
efficacy of Octaplas®
■ The pharmacokinetic study used a median Octaplas® dose of 18 ml/kg (range: 1520), whereas the treatment courses had a higher range with 6-29 ml/kg (median:
18)
■ Octaplas® was fully effective in 81% of patients. In the remaining patients bleeding
was controlled by continuing or increasing treatment with Octaplas®
■ Treatment with Octaplas® was well tolerated and safe
