Targeting Rare Diseases
and Critical Care
AOP Health is the European pioneer for integrated therapies for rare diseases and in critical care.

Founding
Why did you found AOP Health?
“When founding AOP Health in 1996 – as AOP Orphan – my aim was to make targeted treatment available to the maximum number of patients with rare diseases. I realized that these patients are frequently left alone in their suffering. As an entrepreneur the complex environment of rare diseases was a great challenge, but also an opportunity to be successful in this niche.”
What role did AOP Health’s sense of entrepreneurial responsibility play in the founding of the company?
“Entrepreneurial responsibility is no additionally imposed obligation for AOP Health, but the attitude that played an indispensable role at the very time the company was founded. AOP Health’s objective to provide effective help for persons with rare diseases originated from this sense of responsibility and has made the company what it is today.“
AOP Orphan – now AOP Health – was founded in 1996 by Dr. Rudolf Widmann with the aim of developing and providing therapy options for patients with rare diseases, and then introducing the therapy options first in Austria, the European core countries of AOP Health, and finally in the international market.

“I worked for several years in large international pharmaceutical companies and observed that there were some therapy options for rare diseases, but they did not reach the large majority of the patients.”

Sadushi-Kolici R; Jansa P; Kopec G; Torbicki A; Skoro-Sajer N; Campean IA; Halank M; Simkova I; Karlocai K; Steringer-Mascherbauer R; Samarzija M; Salobir B; Klepetko W; Lindner J; Lang IM (Source: https://www.thelancet.com/journals/lanres/article/PIIS2213-2600(18)30367-9/fulltext).

The drug uses a new AOP Orphan-developed dosing algorithm to facilitate the administration and proves to be superior to Esmolol in its ability to reduce heart rate more than blood pressure.
Pitolisant approval
Pitolisant, also known as tiprolisant, is a potent and selective inverse agonist of the histamine H3 receptor (Ki = 0.16 nM), and was approved for the treatment of narcolepsy in 2016. Pitolisant was developed by Jean-Charles Schwartz, Walter Schunack, and colleagues, after the former discovered the H3 receptor. It was the first H3 receptor inverse agonist to be tested in humans or introduced for clinical use.
Beta-blocker for severe sepsis
The paper “Beta-blocker use in severe sepsis and septic shock: a systematic review.” by Sanfilippo F1, Santonocito C2, Morelli A3, Foex P4 describes the ability of beta blockade to modulate sepsis-induced alterations at the cardiovascular, metabolic, immunologic and coagulation levels.

Renaissance of Interferon (IFNα)

The Janus Kinase 2 gene (JAK2) was discovered in 2005. It provides instructions to cells for making the JAK2 protein. The test looks for mutations in JAK2 that are associated with bone marrow disorders caused by the production of too many blood cells.
Prostacyclin Analogues Approval
Subcutaneous prostacyclin analogue approved for the treatment of pulmonary arterial hypertension (PAH) in Europe.
European Union Expansion

Corporate Culture
Since its very start AOP Health has borne the corporate responsibility of further life quality improvement for patients with severe, rare, life-threatening diseases as well as patients in critical conditions. We at AOP Health conduct intensive research for this purpose, believing that developing and providing solutions for patients is the most important part of the AOP Health corporate responsibility. When it comes to wanting the best for the patients, we stand side-by-side with each other as a team, with researchers, physicians, therapists, caregivers and, patient organizations.
AOP Health is keen to keep one of its greatest assets – it is closely networked with the key specialists in all markets and is therefore able to help patients with rare diseases from Austria throughout the world.
The Future
Thanks to our advancements in the field of therapies, an increasing number of patients survive their disease or are able to live with it for a longer period of time. In the next few decades, personalized medicine, individual treatment opportunities will emerge more and more as the standard in AOP Health’s therapy concepts as well.
Novel technologies such as next-generation sequencing (NGS) will play an equally crucial role as the increasing quantities of big data and conclusions derived from the daily lives of patients also beyond the strictly regulated conditions of clinical trials, e.g. real-world evidence.
Furthermore, the increasing health competence, health literacy of patients and their family members will also determine the future of pharma and health care sector.
