Public Summary SwissPAR – Poteligeo®

Public Summary SwissPAR dated 03.12.2021

Poteligeo® (active substance: mogamulizumab)

First authorisation in Switzerland: 1 September 2021

Medicinal product for second-line treatment in adults with relapsed or refractory mycosis fungoides (MF) or Sézary syndrome (SS).

Information on authorisation

Poteligeo, with the active substance mogamulizumab, is used for treatment in the following patients whose cancer has spread despite previous treatment:

  1. Adults with relapsed (recurring) or refractory[1] mycosis fungoides (MF)
  2. Adults with relapsed or refractory Sézary syndrome (SS)

Both diseases are malignant disorders of T lymphocytes (a type of white blood cell) that mainly affect the skin. Since these cancers are rare, life-threatening diseases, Poteligeo has been authorised as an orphan drug. “Orphan drug” is a designation given to important medicinal products for rare diseases.

Poteligeo was authorised under Article 13 of the Therapeutic Products Act (TPA). This means that the medicinal product is already authorised in another country with comparable medicinal product control. In this case, Swissmedic takes into consideration the results of checks carried out by the foreign regulatory agency, provided certain requirements are fulfilled. These involve checks on the quality, efficacy and safety of the medicinal product, and the extent to which the results can be accepted for Switzerland.

The consideration of the results of foreign authorisation procedures is intended to help ensure that medicines that are already authorised abroad can be made available to patients in Switzerland as quickly as possible.

In deciding whether to authorise Poteligeo in Switzerland, Swissmedic accepted the assessment and approval decisions of the European Medicines Agency (EMA) and the U.S. Food and Drug Administration (FDA), and has not conducted its own scientific review.

Accordingly, in the SwissPAR (Swiss Public Assessment Report) and the resulting Public Summary SwissPAR, Swissmedic refers to the Assessment Report and the short report issued by the reference authority: ( (

[1]Refractory: In relation to cancer, refractory means that the cancer is resistant to treatment and does not recede or may even progress, despite treatment.
