Celltrion submitted its aBLA for CT-P43 to the US FDA in June 2023 (and reached a settlement and licence agreement with Johnson & Johnson (J&J) permitting Celltrion to launch CT-P43 in the US on 7 March 2025), and submitted its MAA to EMA in May 2023.

Alvotech announced in its 2023 Q2 Earnings Presentation that it has resubmitted its interchangeable BLA for AVT02, biosimilar to AbbVie’s high concentration Humira® (adalimumab). The company did not disclose the BsUFA date but anticipated launch in 2024.

Outlook Therapeutics announced the FDA issued it with a Complete Response Letter (CRL) for its BLA for ONS-5010, biosimilar to Genentech’s Avastin® (bevacizumab). The FDA acknowledged the NORSE TWO pivotal trial met its safety and efficacy endpoints, but could not approve the BLA due to several chemistry, manufacturing and controls issues, as well as open observations from pre-approval manufacturing inspections and a lack of substantial evidence.

On 28 October 2022, the FDA accepted Outlook Therapeutics’ BLA for ONS-5010 for the treatment of wet age-related macular degeneration. The FDA has set a PDUFA goal date of 29 August 2023.

Alvotech published its first half 2023 financial results, reporting a revenue growth to $22.7M for the six months ending 30 June 2023, compared to $3.9M for the same six months of 2022.  Revenue for that period consisted of product revenue from sales of AVT02 (Alvotech’s adalimumab biosimilar) in select European countries and Canada.  As of 30 June 2023 the company has $60.5M in cash/equivalents (excluding $25.2M in restricted cash) and current borrowings of $808.6M.  Its R&D costs for the six month period ending 30 June 2023 were $99.6M.

The Patent Trial and Appeal Board (PTAB) issued decisions in Celltrion’s two inter partes reviews (IPRs) (IPR2022-00578 and IPR2022-00579), finding Chugai and Roche’s tocilizumab patents (US patent nos. 8,580,264 and 10,874,677) were invalid.  The PTAB found that claims 1-12 of the ‘264 patent were anticipated and/or obvious, and claims 1-8 of the ‘677 patent were obvious. 

The PTAB instituted Celltrion’s two IPRs of Chugai and Roche’s tocilizumab patents on 31 August 2022.

Dong-A published the results of its global Ph III trials of DMB-3114 in January 2023.

Alvotech and Bioventure announced that AVT02, their biosimilar to AbbVie’s Humira® (adalimumab) has been approved (under brand name Adalimumab-EVA®) by the Egyptian Drug Authority.  Bioventure is Alvotech’s exclusive strategic partner for the commercialisation of AVT02 and other biosimilars in the Middle East and North Africa.

Merck stated that Keytruda® is the first immunotherapy approved in the EU for the first-line treatment of this patient population.  Keytruda is approved globally for the treatment of a large range of cancers.  In June 2022 the EC approved Keytruda® for expanded melanoma indications.

On 1 May 2023, BMS announced that the FDA has accepted its sBLA, and the EMA has validated its Type II Variation Application for Reblozyl® (luspatercept-aamt) to treat the above patient group.
