26 MAY 2023 | EU | Celltrion files MAA with EMA for biosimilar to Janssen’s Stelara® (ustekinumab)

Korea Biomed has reported that Celltrion filed a marketing authorisation application with the EMA for CT-P43, its biosimilar to Janssen’s Stelara® (ustekinemab).  Based on its phase III clinical trial in plaque psoriasis patients, which demonstrated similar efficacy, pharmacokinetic, and safety results between CT-P43 and Stelara®, Celltrion’s MAA sought approval for all Stelara® indications.  Celltrion confirmed it intends to seek approval in other key countries.

26 MAY 2023 | EU | FDA approves STADA-controlled Norbitec biologics facility to manufacture and store Pfizer’s Retacrit® (epoetin alfa-epbx) biosimilar to Amgen’s Epogen® /Procrit®

The Pharma Letter has reported that the STADA-controlled Norbitec biologics facility in Uetersen, Germany, has been approved by the FDA to manufacture and store Pfizer’s Retacrit® (epoetin alfa-epbx), biosimilar to Amgen’s Epogen® /Procrit®.  The approval followed a six-day FDA inspection of the German site.

25 MAY 2023 | US | FDA grants priority review of NDA for Takeda and HUTCHMED’s fruquintinib

Takeda and HUTCHMED announced that the FDA granted priority review for the NDA of fruquintinib, a selective inhibitor of vascular endothelial growth factor receptors (VEGFR) -1, -2, and -3, for the treatment of previously treated metastatic colorectal cancer.  The Prescription Drug User Fee Act goal date for the FDA’s decision is set for 30 November 2023.  The NDA submission includes data from the Phase 3 FRESCO-2 trial, which demonstrated significant improvements in overall survival and progression-free survival.  Fruquintinib is currently approved in China under the brand name ELUNATE®.

25 MAY 2023 | EU | EMA accepts MAAs for Sandoz’s denosumab biosimilars to Amgen’s Prolia® and Xgeva®

Sandoz announced that the European Medicines Agency (EMA) has accepted marketing authorisation applications (MAA) for its proposed biosimilar denosumab, for regulatory review.  The two applications include the approved indications for the originator drugs Prolia® and Xgeva®, including osteoporosis in postmenopausal women and in men at increased risk of fractures, treatment-induced bone loss, prevention of skeletal related complications in cancer that have spread to the bone, and giant cell tumor of the bone.

This week Mitsubishi and GlycoNex announced Japanese approval of their phase I clinical trial of SPD8, a denosumab biosimilar to Prolia®.

24 MAY 2023 | US | Amgen provides further details on Stelara® settlement with Janssen

As previously reported, on 22 May 2023 the US District Court of Delaware dismissed Janssen’s patent infringement case against Amgen pertaining to its Stelara® (ustekinumab) biosimilar with prejudice on the basis that each party bears its own costs. The proposed orders made it clear that the parties had settled.

Reuters has since reported a statement by Amgen that the ustekinumab settlement will permit Amgen to sell its biosimilar “no later than January 1st, 2025”, suggesting the permitted launch date may be earlier than 1 January 2025.  As the API patent, one of six patents Janssen asserted in the proceedings, expires on 25 September 2023, we speculate that the agreed launch date is some time between 25 September 2023 and 1 January 2025.

24 MAY 2023 | US | Approval alert: FDA approves Celltrion’s Yuflyma® (adalimumab) biosimilar to AbbVie’s Humira®

Celltrion’s announcement came only three days after Boehringer Ingelheim announced its Humira® biosimilar Cyltezo® autoinjector pen obtained FDA approval.

23 MAY 2023 | JP | PMDA approves Mitsubishi and GlycoNex’s phase I clinical trial for denosumab biosimilar to Amgen’s Prolia®

Mitsubishi Gas Chemical Company, Inc. and GlycoNex announced approval to commence a phase I clinical trial of SPD8 denosumab, biosimilar to Amgen’s Prolia®, from the Japanese Pharmaceuticals and Medical Devices Agency (PMDA).  The companies announced that the first patient has now been enrolled.  The double-blind trial will compare SPD8 with Prolia® in healthy postmenopausal women, who will undergo pharmacokinetic and safety assessments.

This month Boan Biotech commenced its phase III clinical trial for its Prolia® denosumab biosimilar.

23 MAY 2023 | UK | NICE recommends combination of Merck’s Keytruda® (pembrolizumab) and Eisai’s Lenvima® (lenvatinib) for endometrial cancer

The National Institute for Health and Care Excellence (NICE) has issued a final appraisal document recommending Merck’s Keytruda® (pembrolizumab) combined with Eisai’s Lenvima® (lenvatinib) as an option for treating advanced or recurrent endometrial cancer in adults whose cancer has progressed on or after platinum-based chemotherapy who cannot have curative surgery or radiotherapy, in the NHS in England and Wales.

23 MAY 2023 | US | Amgen files motion to intervene in aflibercept proceedings

Amgen filed a motion to intervene in the proceedings on foot between Regeneron and Mylan in West Virginia relating to aflibercept, and has sought to unseal certain documents. Amgen argued that the sealing of the documents blocked the public’s right of access to Court documents, and that the Court has provided no justification for sealing a number of documents.

Regeneron sued Mylan in West Virginia in August 2022, alleging infringement of 24 patents relating to Eylea (including the ‘601 patent), and a 10 day trial has been set down for June 2023, which is 10 months after Regeneron filed its complaint.
