On 7 April 2026, Outlook Therapeutics announced that it has submitted a formal dispute resolution request (FDRR) to the FDA following a Type A meeting in March 2026 in relation to its ophthalmic formulation of bevacizumab, ONS-5010/Lytenava™, for wet AMD.

The FDRR is an appeal process which permits a sponsor to obtain formal review of any FDA decision by raising the matter with the supervisor of the employee who made the decision.  The FDA has accepted Outlook’s  FDRR and has scheduled a meeting with the deciding official in April 2026.

The March 2026 Type A meeting was held to clarify an issue identified in a Complete Response Letter issued by the FDA in December 2025 regarding the second resubmission of Outlook’s Biologics Licence Application (BLA) for ONS-5010/Lytenava™.  In the CRL, the FDA had recommended that additional confirmatory evidence be provided to support the application, though it did not clarify what type of evidence would be acceptable.

In its April 2026 press release, Outlook Therapeutics reiterated that it remains committed to its position “that data on safety and efficacy for Lytenava™ demonstrated in NORSE TWO and NORSE EIGHT provide sufficient evidence to support approval”.

Outlook Therapeutics received a first CRL from the FDA for Lytenava™ in August 2023 and subsequently submitted a Special Protocol Assessment request in December 2023 regarding further clinical trials.  It resubmitted its BLA to the FDA in February 2025 based on positive results of the NORSE EIGHT clinical trial, announced in January 2025.  A second CRL (issued in August 2025) recommended that Outlook submit additional efficacy data to support its application for Lytenava™.  Outlook resubmitted its BLA to the FDA for a second time in early November 2025.

Lytenava™ was approved in the EU in May 2024 and was launched in the UK and Germany for wet AMD in June 2025.  The Scottish Medicines Consortium accepted Lytenava™ for use within NHS Scotland in June 2025.

Intas Pharmaceuticals reportedly has an ophthalmic bevacizumab biosimilar under development, having received approval from India’s CDSCO in March 2025 to conduct Phase 2/3 trials of bevacizumab (solution for intravitreal injection 25mg/mL) in patients with wet AMD.

On 24 March 2026, Singapore-headquartered Prestige Biopharma announced that it is “accelerating commercialisation” of Vasforda®/HD204, biosimilar to Genentech’s Avastin® (bevacizumab), following positive results from its global Phase 3 clinical trial.  The trial was conducted in patients with advanced non-squamous non-small cell lung cancer (NSCLC) and reportedly demonstrated clinical equivalence between Vasforda®/HD204 and Avastin®.

Under an agreement announced in July 2022, Prestige granted exclusive commercialisation rights for HD204 to Intas & Accord Healthcare for the US, Europe, Canada, MENA, Brazil, Mexico, South Africa, Thailand, Vietnam, Philippines, Malaysia, Singapore, Indonesia, Kyrgyzstan and Tajikistan.  According to Prestige, in collaboration with Accord Healthcare, it has been preparing regulatory submissions for US and European markets, with marketing authorisation applications for HD204 expected to be submitted in H2 2026.

The first bevacizumab biosimilar approved in the US was Amgen’s Mvasi® in September 2017, with Mvasi® also being approved in Europe in January 2018.  There are currently five other bevacizumab biosimilars included in the FDA’s approved drugs database: Pfizer’s Zirabev® (June 2019), Amneal’s Alymsys® (April 2022), Celltrion’s Vegzelma™ (September 2022), Bio-Thera/Sandoz’s Avzivi® (December 2023), and Biocon Biologics’ Jobevne™ (April 2025).  More recently, on 13 January 2026, Shanghai Henlius Biotech announced that a Biologics Licence Application (BLA) for its bevacizumab biosimilar, HLX04, was accepted for review by the FDA.

On 5 March 2026, Outlook Therapeutics provided an update on ONS-5010/Lytenava™, ophthalmic biosimilar to Roche/Genentech’s Avastin® (bevacizumab-vikg), following a Type A meeting with the U.S. Food and Drug Administration (FDA).

The Type A meeting was held to clarify an issue regarding substantial evidence of effectiveness identified in the third Complete Response Letter (CRL) issued in December 2025 for the ONS-5010/Lytenava™ Biologics License Application (BLA).  The meeting was also used to discuss potential regulatory approval steps.  Outlook Therapeutics stated it will continue to engage with the FDA to further clarify the FDA’s view on confirmatory evidence and the regulatory path forward.

The March 2026 Type A meeting is the second Type A meeting Outlook Therapeutics has held with the FDA for its ophthalmic bevacizumab biosimilar.  The first Type A meeting occurred in September 2025 to address the second CRL issued in August 2025.  The CRL recommended that Outlook Therapeutics submit additional confirmatory efficacy data to support its application.

Outlook Therapeutics had already resubmitted its BLA to the FDA in February 2025, following receipt of a first CRL from the FDA for ONS-5010 and its submission of a Special Protocol Assessment request in 2023 regarding further clinical trials.  A second CRL (August 2025) recommended Outlook submit additional efficacy data to support its application for ONS-5010. Outlook Therapeutics resubmitted its BLA to the FDA in November 2025, in order to address the issues in the August 2025 CRL.

Outlook Therapeutics received a Complete Response Letter (CRL) from the FDA in December 2025 following a second resubmission of its Biologics Licence Application for Lytenava™.  On 11 February 2026, Outlook Therapeutics announced that it had submitted a Type A meeting request with the FDA.

There is at least one ophthalmic bevacizumab biosimilar under development.  In March 2025, Intas Pharmaceuticals received approval from India’s CDSCO to conduct Phase 2/3 trials for bevacizumab (solution for intravitreal injection 25mg/mL) in patients with wet AMD.

On 13 January 2026, Shanghai Henlius Biotech announced that its Biologics Licence Application (BLA) for HLX04, biosimilar to Roche/Genentech’s Avastin® (bevacizumab) has been accepted for review by the FDA.

HLX04 has previously been approved in China (2021) and in multiple Latin American countries, including Bolivia, the Dominican Republic, and Mexico.  In October 2020, Henlius entered into a co-development and exclusive licensing agreement with Hong Kong-headquartered EssexBio, under which EssexBio was granted an exclusive licence to develop, manufacture and commercialise HLX04 globally.

The first bevacizumab biosimilar approved in the US was Amgen’s Mvasi® in September 2017.  There are currently five other bevacizumab biosimilars included in the FDA’s approved drugs database: Pfizer’s Zirabev® (June 2019), Amneal’s Alymsys® (April 2022), Celltrion’s Vegzelma™ (September 2022), Bio-Thera/Sandoz’s Avzivi® (December 2023), and Biocon Biologics’ Jobevne™ (April 2025).

Henlius also has an ophthalmic preparation based on HLX04 under development, which is intended for the treatment of wet AMD.  In August 2025, a new drug application for Henlius’ ophthalmic bevacizumab biosimilar, HLX04-O, was accepted for review by China’s Center for Drug Evaluation of the National Medical Products Administration.

On 31 December 2025, Outlook Therapeutics announced that the FDA issued a Complete Response Letter (CRL) regarding the second resubmission of its Biologics Licence Application (BLA) for its ophthalmic formulation of bevacizumab, ONS-5010/Lytenava™, for wet AMD.

The CRL comes 7 weeks after the FDA accepted Outlook’s second resubmission of its BLA for Lytenava™ in November 2025.  In the CRL, the FDA indicated that the mechanistic and natural history data added in the BLA resubmission did not alter its earlier assessment.  While the FDA acknowledged that the single adequate and well-controlled study demonstrated efficacy, it again recommended that additional confirmatory evidence be provided to support the application, though did not clarify what type of evidence would be acceptable.

Bob Jahr, CEO of Outlook Therapeutics, stated that while Outlook is “disappointed and disagree[s] with this decision”, they are “fully committed to taking all necessary steps to receive approval in the United States”.
