Investigator-Initiated Studies

CSL Behring Investigator-Initiated Studies

CSL Behring is committed to saving lives and improving the quality of life for people with rare and serious diseases worldwide. This commitment is reflected in the support for Investigator-Initiated Studies (IIS) that advance medical and scientific knowledge of CSL Behring products and the diseases they have been designed to treat. CSL Behring also supports innovative clinical and basic science studies that address important medical and scientific questions related to our therapeutic areas of focus.

Areas of Focus:

The CSL Behring IIS program is open to physicians, researchers and institutions interested in conducting their own research. We receive many requests for support and carefully evaluate each one with priority given to proposals that align with our interests. To facilitate your application, please carefully read the application requirements.

Disclaimer: Any application to participate in CSL Behring’s IIS program, including any information shared in connection with such application, will be used by CSL Behring for the sole purpose of evaluating the application, and will not be shared externally.  To the extent that an application contains personal information about an individual, such information will be treated in accordance with CSL Behring’s privacy policy.

Research Priorities and Eligibility


Primary Immunodeficiency (PI) Diseases

Proposals that increase the knowledge of the efficacy and safety of immunoglobulins in PI indications, specifically route of administration, subclinical infections in diagnosed PI patients with respiratory tract engagement, quality-of-life, wear-off, manual push, flexible dosing/patient preference, and undiagnosed PI.

Secondary Immunodeficiency (SI) Diseases

Proposals that increase the knowledge of the efficacy and safety of immunoglobulins in SI indications, specifically the combination of immunoglobulins with products that cause drug-induced SI in conditions such as multiple myeloma (MM) and chronic lymphocytic leukemia (CLL).

Peripheral Neuropathy

Proposals that increase the knowledge of efficacy and safety of immunoglobulins, specifically pharmacokinetics in chronic inflammatory demyelinating polyneuropathy (CIDP) including wear-off, dose titration, dose conversion from intravenous immunoglobulins (IVIg) to subcutaneous immunoglobulins (SCIg), loading dose and dosing by body mass index (BMI) or fat percent versus weight, quality-of-life in CIDP patients, health economics in CIDP and specific sub-populations, such as elderly and pediatric patients.

Hereditary Angioedema (HAE)

  • Health Outcome studies on C1 Esterase Inhibitor (C1-INH) including quality of life and adherence
  • Clinical studies and experience with novel treatment strategies for C1-INH Replacement Therapy
  • Use of C1-INH in special patient populations (eg; pregnancy, pediatrics)


We seek to advance science and improve patient care with CSL Behring's products in the field of hematology. Through total or partial funding, we support external investigators who initiate, design and implement high-quality hematological research that is focused on our recombinant products, Coagulation Factor IX (Recombinant) Albumin Fusion Protein and Antihemophilic Factor (Recombinant) Single Chain, and our plasma products, Human Plasma Derived von Willebrand Factor (HP-vWF/FVIII) concentrate, Fibrinogen, and Prothrombin complex concentrate [human]. Support is provided based on the scientific merit of the proposal as well as alignment with the following specific areas of interest:

Hemophilia A and B

  • Clinical studies and experience in transitioning to our recombinant coagulation factor products including on-demand treatment and prophylaxis
  • Health outcome studies, including factor consumption, quality-of-life data
  • Health economic outcome studies
  • Clinical studies that focus on long-term joint health and radiographic imaging to assess and monitor joint damage
  • Use in special populations including women
  • Real-world evidence of hemophilia A and B management

Hemophilia A only

  • Role of von Willebrand Factor (vWF) in reducing inhibitor development
  • Clinical studies that increase knowledge of immune tolerance induction with our recombinant Coagulation Factor VIII product

Von Willebrand Disease

  • Clinical studies that generate evidence of efficacy or safety in selected von Willebrand Disease populations specifically: low vWF, type 3, type 2, menorrhagia, pregnancy, or prophylaxis for angiodysplasia, epistaxis and joint bleeds 
  • Generate data supporting efficacy & safety, and health economic benefits of high-ratio pdvWF/FVIII vs. 1:1 concentrates
  • Generate data in vWD (including burden of disease), increase awareness of vWD & show benefit of treatment

(Studies with head to head comparisons with other products are excluded)

Oral Anticoagulant-Associated Bleeding

  • Clinical studies and experience with prothrombin complex concentrates (PCCs) for the management of acute major bleeding in patients treated with Vitamin K antagonists (VKAs) or direct oral anticoagulants (DOACs)
  • Clinical studies and experience with PCCs for urgent reversal prior to emergency surgery or procedures in patients treated with VKAs or DOACs

Acquired Bleeding

  • Clinical studies of PCCs as hemostatic agents in perioperative bleeding and trauma-induced coagulopathy
  • Basic science research with PCCs in trauma-induced coagulopathy


  • Clinical Studies of Fibrinogen as an hemostatic agent 
  • Basic science studies of Fibrinogen as an hemostatic agent


We seek to advance science and improve patient care with CSL Behring's products in respiratory diseases. Through total or partial funding, we support external investigators who initiate, design and implement high-quality respiratory research that is focused on the use of our Alpha-1 Antitrypsin inhibitor to generate data on:

  • Prevalence, epidemiology, natural course of disease and the development of new biomarkers to monitor disease progression
  • Burden of disease
  • Pathophysiology of Alpha-1 Antitrypsin deficiency

Cardiovascular and Metabolic

CSL is committed to developing novel therapies that save and improve the lives of patients with serious and life-threatening diseases. As part of this commitment, we are focused on the leading cause of death worldwide - Cardiovascular and Metabolic diseases..
Our goal in Cardiovascular and Metabolic disease is to address areas of high, unmet medical need and we continue to explore opportunities to work with external investigators to better define and address these needs.


We seek to advance science and improve patient care with CSL Behring's products in the field of transplantation. Through the provision of drug and/or total or partial funding, we support high-quality transplantation research that is initiated, designed, implemented, and sponsored by external investigators to better define unmet medical needs and explore the use of products including complement inhibitors, Clazakizumab and Alpha-1 Antitrypsin in cell and organ transplantation.
Specific Research Priorities include:.
Graft versus Host Disease (GvHD) following:

Hematopoietic Cell Transplant (HCT)

  • Burden of disease, natural course of disease, and understanding the role of conditioning regimens in incidence/severity of acute GvHD.
  • Use of biomarkers to identify patients at risk for GvHD
  • Use of Alpha-1 Antitrypsin to prevent/ameliorate acute GvHD through mechanistic and early/pilot clinical studies 
  • Studies aimed at defining and understanding the immunomodulatory effects of Alpha-1 Antitrypsin

Ischemia/Reperfusion Injury

  • Use of complement inhibitors and Alpha-1 Antitrypsin to prevent/ameliorate ischemia reperfusion injury as a cause of delayed graft function/diminished organ survival through mechanistic, biomarker and clinical pilot studies
