Tillotts Pharma AG under Agreement to Acquire Rights for DIFICLIRTM (fidaxomicin) from Astellas Pharma Europe Ltd.

  • Tillotts Pharma AG has acquired the rights to DIFICLIRTM (fidaxomicin) from Astellas Pharma Europe Ltd for Europe, Middle East, Africa and selected CIS
  • The agreement allows Tillotts to provide a first-line treatment option to patients suffering from CDI, a serious and sometimes life threatening infection of the colon
  • With this acquisition, Tillotts plans to open additional affiliates in Europe in the near future


RHEINFELDEN, Switzerland, 27.11.2020 – Tillotts Pharma AG (“Tillotts”), part of the Japanese Zeria Group, is pleased to announce that it has acquired the rights to DIFICLIRTM (fidaxomicin) from Astellas Pharma Europe Ltd. (“Astellas Europe”) which is subsidiary of Astellas Pharma Inc. (“Astellas”). Under the terms of the agreement, Tillotts will pay EUR 109 million to acquire the product rights from Astellas Europe in the following regions: Europe, Middle East, Africa and selected Commonwealth of Independent States (CIS). Since February 2011, DIFICLIRTM  has been licensed by Astellas from Merck & Co., Inc. Kenilworth, N.J., U.S.A., known as MSD outside the U.S. and Canada (“Merck”).

DIFICLIRTM (fidaxomicin) is a narrow-spectrum macrocyclic anti-bacterial agent available as film-coated tablets and granules. It is indicated for the treatment of Clostridioides difficile infections (CDI), also known as C. difficile-associated diarrhoea (CDAD) in adults and paediatric patients  with a body weight of at least 12.5 kg. CDI is an infection caused by the toxins of the spore-forming bacterium Clostridioides difficile, estimated to affect more than one hundred thousand people in Europe per year. Symptoms vary, but often include diarrhoea stomach pain and fever.

“I am extremely pleased to acquire the EU rights for DIFICLIRTM. Not only does it have great synergies with our existing GI-portfolio, it is also an important strategic agreement, as it will allow us to expand our presence and open additional affiliates in Europe. We are very excited about this transaction, and I would like to thank Astellas for this collaboration and making the transition straight forward,” CEO of Tillotts Pharma, Thomas A. Tóth von Kiskér, says.

COO of Tillotts Pharma, Mattias Norrman, continues, “CDI is a very serious, life threatening condition that can impact vulnerable populations such as the elderly, cancer patients and people with weak immune systems. DIFICLIRTM offers a range of formulations that can demonstrate significant benefit for a wide range of patients suffering from CDI. Using DIFICLIRTM to treat patients at high risk can reduce the risk of reoccurrence, which improves the chances of positive outcomes. Ultimately, this may help to eliminate additional costs associated with treating CDI.”

With the acquisition of DIFICLIRTM, Tillotts reaffirms its commitment to patients by providing treatments for a wide range of disorders of the GI tract, while delivering value to shareholders by expanding and diversifying the company’s portfolio. The agreement includes all trademarks and relevant IP assets, marketing authorisations, relevant contracts with third parties (to the extent solely dedicated to the product and assignable, including manufacturing) and inventory. The transaction does not include the transfer of any Astellas employees or facilities.
