On 26 February 2024, AstraZeneca announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency has recommended the use of Voydeya® (danicopan) as an add-on to ravulizumaboreculizumab for the treatment of adult patients with paroxysmal nocturnal haemoglobinuria (PNH) who have residual haemolytic anaemia.   

CHMP based its positive opinion on results from the ALPHA Phase III trial which were published in The Lancet Haematology journal on 27 November 2023.

PulseNews reported that Samsung Bioepis has received approval for Episcli® (SB12), biosimilar to Alexion’s Soliris® (eculizumab), from the Korean Ministry of Food and Drug Safety.  Episcli® is approved to treat nocturnal hemoglobinuria.

On 3 January 2024 Alexion sued Samsung Bioepis in the US District Court for the District of Delaware asserting infringement of six of its eculizumab patents.

January 3, 2024

Alexion filed a complaint against Samsung in the US District Court for the District of Delaware asserting infringement of six US eculizumab patents.  The allegations relate to Samsung’s abbreviated Biologics License Application (aBLA)  for SB12, its biosimilar to Alexion’s Soliris® (eculizumab), accepted by the US Food and Drug Administration (FDA) on 7 July 2023.  Soliris® is a treatment for patients with paroxysmal nocturnal hemoglobinuria (PNH) and other conditions.  On 7 July 2023, Samsung provided its 180-day notice of commercial marketing to Alexion.

In August 2023, Amgen appealed Alexion’s successful preliminary injunction order regarding Amgen’s off-label use of its eculizumab biosimilar Bekemv® in Germany.

The US Patent Trial and Appeal Board (PTAB) has instituted two more of Samsung Bioepis’ inter partes review (IPR) petitions challenging Alexion’s Soliris® (eculizumab) patent.  The IPRs relate to US patent nos. 10,590,189 and 10,703,809 in IPR proceedings IPR2023-01069 and IPR2023-01070 respectively.  The patents cover method of treatment claims in treating paroxysmal nocturnal hemoglobinuria (PNH).

On 8 December 2023, PTAB instituted three other Samsung Bioepis petitions against Alexion’s Soliris® patent: US patent nos. 9,725,504, 9,718,880 and 9,732,149.  Samsung Bioepis launched Epysqli®, biosimilar to Soliris®, in three European countries on 19 October 2023.  Epysqli® was approved by the EMA on 30 May 2023.

October 19, 2023

October 18, 2023

AstraZeneca announced that the Chinese National Medical Products Administration (NMPA) has approved Soliris® (eculizumab) to treat a new indication: neuromyelitis optica spectrum disorder (NMOSD).  Soliris® is the first and only complement inhibitor approved for the treatment of NMOSD in China.

On 24 August 2023 Soliris® was approved in Japan for a new indication to treat paediatric patients with generalised myasthenia gravis.

August 24, 2023

AstraZeneca announced that Japan’s Ministry of Health, Labour and Welfare (MHLW) has granted approval for the extended use of Soliris® (eculizumab) to treat paediatric patients suffering from generalised myasthenia gravis (gMG).  This approval specifically targets those who are anti-acetylcholine receptor (AChR) antibody-positive and whose symptoms are difficult to control through high-dose intravenous immunoglobulin (IVIG) therapy or plasmapheresis (PLEX).  Soliris® is the exclusive targeted therapy cleared for treating gMG in Japanese children and adolescents.

On the same day AstraZeneca also announced the MHLW expanded approval for it and Merck’s Lynparza® (olaparib) with abiraterone to treat BRCAm mCRPC.

Managing IP has reported that Amgen filed an appeal with Germany’s Federal Court of Justice against a preliminary injunction order made by the Munich District Court on 4 August 2023.  The preliminary injunction prevents Amgen from supplying Bekemv®, its biosimilar to Alexion’s Soliris® (eculizumab), in Germany unless certain conditions are met, including a requirement that Amgen customers, including hospitals, agree not to use Bekemv® off-label.

On 19 April 2023, the EMA approved Bekemv® for the treatment of paroxysmal nocturnal haemoglobinuria (PNH) (after the CHMP provided its positive opinion on 23 February 2023).  Alexion successfully applied to the Munich Regional Court for a preliminary injunction in May 2023, which was upheld by the 4 August 2023 District Court ruling.

The ODE rights expired in June 2019 for PNH.   However Alexion argued that there was a real risk that the biosimilar would be used off-label to treat other conditions over which Alexion still has exclusive rights.  The District Court noted that by sending letters of recommendation to medical practitioners, Amgen contributed to the risk of Bekemv®’s off-label use.

Alexion has also sued Samsung Bioepis in Germany over its eculizumab biosimilar Epysqli®, approved by the EMA on 30 May 2023, with a preliminary injunction hearing scheduled for 16 August 2023.

June 26, 2023

AstraZeneca announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) recommended the MA for Astra Zeneca’s Soliris® (eculizumab) be expanded to include the treatment of refractory generalised myasthenia gravis (gMG) in children and adolescents aged six to 17 years who are anti-acetylcholine receptor antibody-positive.  AZ confirmed that regulatory submissions for Soliris® for the treatment of paediatric patients with gMG are pending or planned with multiple health authorities.

On 13 June 2023 the Chinese NMPA approved Soliris® for treatment of gMG in adults who are anti-acetylcholine receptor antibody-positive.

June 21, 2023

Samsung Bioepis has filed an IPR in the US against Alexion’s Soliris® (eculizumab) patent 10,703,809 (’809 patent) advocating that all claims of the ‘809 patent are obvious in light of the prior art (including patent applications, a granted patent, manuscripts and a journal article).

On the same day, Samsung Bioepis also filed an IPR against Janssen’s Stelara® (ustekinumab) patent no. 10,961,307 (‘307 patent), addressed here

June 13, 2023

AstraZeneca announced that the Chinese NMPA has approved Soliris® (eculizumab) for treatment of refractory generalised myasthenia gravis (gMG) in adults who are anti-acetylcholine receptor (AChR) antibody-positive. This is the third approved indication approved for Soliris® in China, and is the first and only complement inhibitor approved to treat gMG in China.  The NMPA’s approval was based on results of the Phase III REGAIN trial in which Soliris® demonstrated clinical benefit for patients with anti-AChR antibody-positive gMG who had previously failed immunosuppressive treatment and suffered significant unresolved disease symptoms.

Biosimilars to Soliris® are in the pipeline: on 30 May 2023 Samsung Bioepis’ Epysqli® (eculizumab) was approved in Europe to treat paroxysmal nocturnal hemoglobinuria, and on 23 February 2023 the CHMP recommended MA for Amgen’s Bekemv® for the same condition.

May 30, 2023

The European Commission (EC) has granted Marketing Authorisation for Samsung Bioepis’ Epysqli® (eculizumab), biosimilar to Alexion’s Soliris®.  Epysqli® is approved for the treatment of adult and children patients with paroxysmal nocturnal hemoglobinuria (PNH), and is Samsung Bioepis’ first hematology biosimilar.
