Neupogen® | Filgrastim (GCSF) | Amgen

06 Oct 2020 | All | Sandoz | Onco'Zine reports a new study released by the American Society of Clinical Oncology Quality Care Symposium indicates that Sandoz's Zarxio® (biosimilar filgrastim) is not only safe and effective, but is cost effective in treating chemotherapy-induced febrile neutropenia in early-stage breast cancer patients.

30 Jun 2020 | US | Amgen | The US District Court of Delaware refuses to combine Amgen's two actions against Pfizer and Hospira relating to filgrastim. The original action was filed in July 2018, and the more recent action was filed in April 2020. In the oral order, (available courtesy of Goodwin), the Court ruled that as Amgen would not agree to use the same experts for both cases, they should bear the consequences of litigating an action nearly two years after the original action. The Court also indicated that it would entertain Pfizer/Hospira's proposed motion to stay the second action.

30 Apr 2020 | US | Amgen, Hospira | Amgen filed suit against Hospira and Pfizer, alleging infringement of US patent 10,577,392, relating to the manufacture of Neupogen®. Interestingly, the patent was only granted on March 03, 2020, nearly 2 years after Hospira launched Nivestym®.

03 Jan 2020 | All | Pfizer, Amgen | New study demonstrates noninferiority of Pfizer's Nivestim® to reference Neupogen®. Additionally, the study demonstrated that those in the biosimilar group reported a shorter median hospitalisation period by two days.

23 Dec 2019 | US | Amgen, Tanvex | Amgen and Tanvex file a joint stipulation of dismissal in their filgrastim dispute. The stipulation of dismissal states that parties will bear their own costs and attorney's fees.

12 Dec 2019 | CA | Apotex | A new study released by the Universities of Saskatchewan and Alberta reveal substantial savings for health services switching to Apotex's Grastofil®. The study analysed Canadian sales between 2016 and 2018, finding that the biosimilar accounted for $13,443,873 in savings, but could have accounted for $36,348,476 in savings had it been used in 100% of cases.

28 Nov 2019 | US | Amneal, Amgen | Amneal and Amgen settle patent dispute over filgrastim biosimilar. Notice of the settlement was approved by a US Federal Court, however no further details have been published. Amgen had filed the complaint against Amneal in March 2018, alleging infringement of a number of patents.

25 Sep 2019 | US | Tanvex | FDA issues a complete response letter for Tanvex's proposed filgrastim biosimilar. Tanvex has announced that the FDA did not request additional clinical data or express concern related to product safety, but that certain items needed to be addressed before the application could be approved.

23 Jul 2019 | US | Amgen, Tanvex | Amgen files new patent infringement suit against Tanvex. Amgen's complaint alleges that Tanvex did not provide certain manufacturing information required by BPCIA legislation.

30 Jun 2019 | All | Sandoz | Study reveals outcomes for the use of filgrastim in stem cell mobilisation prior to transplant, recording similar outcomes for tbo-filgrastim, the reference drug and biosimilar filgrastim (Zarxio).

08 May 2019 | US | Amgen, Sandoz | Federal Court affirms District Court finding Sandoz did not infringe Amgen's '837 patent.[if gte mso 9]><xml> <o:OfficeDocumentSettings> <o:AllowPNG></o:AllowPNG>
