Samsung Bioepis Showcases Strong Patient Subgroup Consistency for Biosimilar Denosumab

On 17 April 2026, Samsung Bioepis announced new clinical data reinforcing the efficacy of its denosumab biosimilar, SB16 (Obodence®, referred to in the US as Ospomyv®), and highlighting consistent outcomes across diverse patient subgroups.  The findings were presented at the World Congress on Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (WCO-IOF-ESCEO) held in Prague from 16-19 April 2026.

The data results from a Phase 3 clinical trial of SB16 involving 456 postmenopausal women with osteoporosis.  The subgroup analysis assessed the consistency of treatment effects across key patient characteristics, including age, body mass index, prior oral bisphosphonate use, smoking status, and presence of vertebral fractures.

SB16 demonstrated comparable efficacy to the reference product (Amgen’s Prolia® (denosumab)) across all evaluated subgroups.  According to Samsung Bioepis, the results further strengthen the “totality of evidence” supporting SB16’s biosimilarity.

Samsung Bioepis’ Ospomyv® was the second Prolia® biosimilar approved in the US (in February 2025) and was scheduled to be offered on US formularies from 1 April 2026BPCIA litigation commenced by Amgen alleging that Samsung Bioepis’ denosumab biosimilars infringed 36 US patents relating to denosumab was settled in September 2025.  Samsung Bioepis’ denosumab biosimilars have also been approved elsewhere, including Europe (February 2025, Obodence® launched from December 2025), Korea (Obodence® launched July 2025), and Australia (July 2025, not yet launched).

Mabwell Secures Expanded Indication in China & Licensing Deal in Malaysia for Denosumab Biosimilars

On 15 April 2026, Mabwell announced that China’s National Medical Products Administration (NMPA) has approved the supplemental Biologics Licence Application for Maiweijian™, biosimilar to Amgen’s Xgeva® (denosumab).  The approval expands the product’s indication to include the treatment of patients with multiple myeloma to prevent skeletal-related events and patients with bone metastases from solid tumours.

Maiweijian™ was initially approved by the NMPA in April 2024 for the treatment of giant cell tumour of the bone that is unresectable or where surgical resection may lead to severe functional impairment.  It was developed by Mabwell’s wholly owned subsidiary, T-mab.  Mabwell’s Mailishu®, biosimilar to Amgen’s Prolia® (denosumab), was approved by the NMPA in March 2023.

A day after the approval in China, on 16 April 2026, Mabwell announced that it entered into a licensing and commercialisation agreement with an unidentified strategic business partner for Maiweijian™ and Mailishu® in Malaysia.  Under the terms of the agreement, the partner will be responsible for the registration and commercialisation of the denosumab biosimilars in Malaysia, whilst Mabwell will be responsible for the development, manufacturing and supply of the biosimilars.

US Appeals Court Confirms No Preliminary Injunction Preventing Samsung Bioepis from Private Label Ustekinumab Supply

On 14 April 2026, the US Court of Appeals for the Third Circuit published its judgment confirming the District Court’s decision to refuse to grant a preliminary injunction to prevent Samsung Bioepis from supplying its biosimilar ustekinumab to Cigna’s Quallent.

The decision arises from a complaint filed by Johnson & Johnson/Janssen in the US District Court for the District of New Jersey on 24 February 2025 alleging that Samsung Bioepis had breached a settlement and licence agreement entered in July 2023 (announced in November 2023).  The agreement permitted Samsung Bioepis to launch Pyzchiva®/SB17 (ustekinumab), biosimilar to J&J/Janssen’s Stelara®, in the US from 22 February 2025.  In November 2024, Samsung Bioepis entered into a Private Label Distributor (PLD) Agreement with Quallent Pharmaceuticals Health LLC, a subsidiary of the Cigna Group.  J&J/Janssen alleged that the sublicence to Quallent breached the settlement agreement and Janssen filed a motion for a preliminary injunction to prevent Samsung from supplying Quallent or authorising Quallent to distribute SB17 while the litigation was pending.

The US District Court refused to grant a preliminary injunction on the basis that Janssen had failed to establish that it would suffer irreparable harm if the injunction was not granted.  The Appeals Court found no error in that decision.  J&J/Janssen’s underlying breach of contract case remains ongoing.

Pyzchiva® was launched in the US by Sandoz in February 2025 (in PFS and vial forms), under a September 2023 development and commercialisation agreement with Samsung Bioepis.  That agreement gives Sandoz the right to commercialise Pyzchiva® in the US, as well as Europe, Switzerland, the UK and Brazil.  Pyzchiva® was launched in Europe in July 2024 and a Pyzchiva® autoinjector was launched in May 2025 as the first commercially available biosimilar ustekinumab pre-filled pen in Europe.

J&J has previously entered into ustekinumab settlement agreements with Amgen (which launched its biosimilar, Wezlana®, in the US in early January 2025 through Optum Health Solution’s private label subsidiary Nuvaila), Alvotech and Teva (Selarsdi® launched on 21 February 2025), Biocon (Yesintek™ launched on 24 February 2025), Celltrion (Steqeyma® launched March 2025), and Fresenius Kabi and Formycon (Otulfi® launched March 2025).  Other ustekinumab biosimilars launched in the US include Dong A-ST/Accord’s Imuldosa® (launched August 2025) and Bio-Thera/Hikma’s Starjemza™ (launched November 2025).

Henlius’ Cetuximab Biosimilar IND Application Approved in China

On 14 April 2026, Shanghai Henlius Biotech announced that China’s National Medical Products Administration (NMPA) has approved an Investigational New Drug (IND) application for HLX05-N, biosimilar to Eli Lilly/Merck KGaA’s Erbitux® (cetuximab), for the treatment of metastatic colorectal cancer (mCRC).

According to Henlius, it now plans to commence an international multicentre Phase 1 clinical study of HLX05-N “once the necessary conditions are met”.

Other cetuximab biosimilars have been approved globally, primarily for the treatment of mCRC and head and neck squamous cell carcinoma (HNSCC).  Alkem’s Cetuxa™ was reportedly the first cetuximab biosimilar to be approved and launched, having been approved in India in January 2023 and launched in May 2023.  Alkem’s biological arm, Enzene, entered into a strategic collaboration with Lupin in May 2023 for Indian commercialisation of Cetuxa™.  Simcere Zaiming/Mabpharm’s Enlituo® (cetuximab beta) was approved in China in June 2024.  In February 2026, R-Pharm’s Arcetux™ (cetuximab) was the first biosimilar cetuximab to gain approval in Russia.

Sandoz’s Philippines Business Acquired by Lotus Pharmaceutical

On 2 April 2026, Taiwan-headquartered Lotus Pharmaceutical announced that it has entered into an agreement to acquire Sandoz AG’s Philippines business.  The acquisition is expected to be completed in Q2 2026, subject to closing conditions.

On completion, Lotus will undertake the sales and marketing of Sandoz Philippines’ existing products, including biosimilars and generics covering therapeutic areas such as cardiovascular and oncology.

Daiichi Sankyo/MSD’s Ifinatamab Deruxtecan Granted FDA Priority Review

On 13 April 2026, Daiichi Sankyo announced that the FDA has accepted for priority review a Biologics License Application (BLA) for Daiichi Sankyo/MSD’s ifinatamab deruxtecan (I-DXd) for the treatment of extensive-stage small cell lung cancer (ES-SCLC) with disease progression on or after platinum-based chemotherapy.  Ifinatamab deruxtecan was granted Breakthrough Therapy Designation by the FDA for the same indications in August 2025.

The FDA review of the BLA is being conducted under Project Orbis, an initiative of the FDA’s Oncology Center of Excellence that provides a framework for the collaborative review of new cancer treatments among international regulatory partners.  It is also being reviewed under the FDA’s Real-Time Oncology Review (RTOR) program, which facilitates earlier submission of topline efficacy and safety results, prior to the submission of the complete application, to support an earlier start to the FDA’s evaluation of the application.

In October 2023, Daiichi Sankyo and MSD entered into a global development and commercialisation collaboration for three of Daiichi’s deruxtecan antibody-drug conjugates (ADCs), including ifinatamab deruxtecan.  Under that agreement, Daiichi and MSD agreed to jointly develop and commercialise the ADCs around the world, excluding Japan where Daiichi retains exclusive commercialisation rights.  Daiichi is solely responsible for manufacture and supply of the products.

New Indication Alert: Regeneron/Sanofi’s Dupixent® (Dupilumab) EU-Approved for Young Children with CSU

On 13 April 2026, Regeneron and Sanofi announced that Dupixent® (dupilumab) has been approved by the European Commission for the treatment of moderate-to-severe chronic spontaneous urticaria (CSU) in children aged 2 to 11 years with inadequate response to histamine-1 antihistamines and who are naive to IgE therapy for CSU.  The approval follows a positive CHMP opinion for the indication in February 2026.

The existing CSU indication in Europe (approved in November 2025) had covered adults and adolescents (12 years and above).  According to Regeneron, an sBLA has been accepted for review in the US seeking approval for Dupixent® in children aged 2 to 11 years with CSU, with a decision expected by April 2026.

Biosimilar dupilumab is under development by at least Samsung Bioepis, Bio-Thera Solutions and Costa Rican-based SteinCares, Alvotech and Advanz and Binnopharm and Mabwell.  In August 2025, CSPC Pharmaceutical announced that it received approval from China’s National Medical Products Administration (NMPA) to conduct clinical trials of its dupilumab injection.

BioNTech and DualityBio Report Phase 2 Success as Trastuzumab Pamirtecan BLA Advances in China

On 11 April 2026, BioNTech reported positive results for BioNTech and DualityBio’s investigational antibody drug conjugate, BNT323/DB-1303 (trastuzumab pamirtecan) in a Phase 2 cohort of patients with HER2-expressing, advanced endometrial cancer.  The results are part of a global Phase 1/2a study assessing the safety and tolerability of trastuzumab pamirtecan in multiple solid tumours.

The Phase 2 cohort included 145 patients and, according to BioNTech, met its primary efficacy endpoint, with data demonstrating clinically meaningful antitumor activity across all HER2 expression levels and a manageable safety profile.

BioNTech and DualityBio intend to file a Biologics License Application (BLA) in the US in 2026, “subject to regulatory feedback from the FDA”.

A BLA has already been filed for BNT323/DB-1303 in China, with DualityBio announcing on 9 April 2026 that the BLA had been accepted for review by China’s National Medical Products Administration (NMPA) in respect of the treatment of unresectable or metastatic HER2-postiive adult breast cancer.

Trastuzumab pamirtecan is being developed by BioNTech and DualityBio and was “built from” DualityBio’s Duality Immune Toxin Antibody Conjugates (“DITAC”) platform.  In addition to the Phase 1/2 trial in patients with advanced/metastatic solid tumours, the ADC is being evaluated in two global Phase 3 trials: Fern-EC-01 (HER2 expressing advanced recurrent endometrial cancer) and DYNASTY-Breast02 (metastatic breast cancer).

Replimune Announces Job Losses, Blames FDA Process, as RP1 Development Ends

On 10 April 2026, Replimune announced that the FDA had issued a complete response letter (CRL) to its BLA for RP1 (vusolimogene oderparepvec) in combination with nivolumab for the treatment of advanced melanoma.  Sushil Patel, Ph.D., CEO of Replimune said, “As we previously communicated, without timely accelerated approval, the development of RP1 will not be viable. We are devastated for our committed employees who have worked tirelessly for patients but at this point we have no choice but to eliminate jobs, including substantially scaling back our U.S. based manufacturing operations.”

Replimune criticised several aspects of the CRL, claiming that the FDA “appears to have contradicted their positions expressed at the September 2025 Type A meeting.”  Replimune noted that the FDA did not repeat its previous concerns about the heterogeneity of the patient population in the relevant clinical trial, and that it acknowledged that randomizing patients to an anti-PD1 only arm in the confirmatory study was not feasible.

Replimune submitted the BLA in November 2024 under the FDA’s Accelerated Approval pathway, with the FDA also granting Breakthrough Therapy Designation.

Apotex’s Generic Ozempic® (Semaglutide) Secures First FDA Tentative Approval

On 10 April 2026, Apotex announced that it received the first US FDA Tentative Approval for its Abbreviated New Drug Application (ANDA) for Semaglutide Injection, a generic version of Novo Nordisk’s Ozempic®.  FDA Tentative Approval signifies that Apotex’s product meets all statutory and regulatory requirements for approval but cannot be marketed in the US because of patents or exclusivities related to the reference drug.

Apotex developed its Semaglutide Injection through a strategic partnership with Orbicular Pharmaceutical Technologies, headquartered in India.

The FDA Tentative Approval gives Apotex an opportunity to be one of the first to launch generic Ozempic® in the US following expiry of Novo Nordisk’s exclusivity/patents.  Numerous generic semaglutide products launched on the Indian market in March 2026, including by Dr Reddy’s Zydus, Alkem, Sun Pharma and Glenmark, following expiry of Novo Nordisk’s core Indian patent for semaglutide.

Apotex’s news follows Novo Nordisk’s announcement on 20 March 2026 that the FDA approved a new higher dose (7.2 mg) of Wegovy® (semaglutide) injection (Wegovy® HD) for weight loss and long-term maintenance of weight loss for certain adult patients.  The approval was granted under the Commissioner’s National Priority Voucher (CNPV) pilot program.  Wegovy® HD was subsequently launched in the US in April 2026.

On 1 April 2026, Shanghai Henlius Biotech announced that its Investigational New Drug (IND) application for HLX319, biosimilar to Genentech/Roche’s Phesgo® (Perjeta® (pertuzumab), Herceptin® (trastuzumab) and hyaluronidase), has been approved by China’s National Medical Products Administration (NMPA).  Shortly after, on 10 April 2026, the company reported that the first patient in its phase I clinical trial, HLX319-001, had been dosed.

HLX319 is intended for neoadjuvant/adjuvant treatment of HER2-positive early or locally advanced breast cancer, as well as for the treatment of metastatic breast cancer.  The pertuzumab and trastuzumab used in HLX319 are Henlius’ self‑developed HLX11/Poherdy® and HLX02/Hanquyou®, together with a proprietary recombinant human hyaluronidase (rHuPH20).

In February 2026, HLX11/Poherdy® (pertuzumab) received a positive CHMP opinion in Europe for use (with trastuzumab and docetaxel) in adults with HER2-positive metastatic or locally recurrent unresectable breast cancer.  It was also the first biosimilar to Genentech/Roche’s Perjeta® approved in the USA where a legal challenge was settled in January 2026.

HLX02/Hanquyou® (trastuzumab) has been approved in China since 2020, and under different names in Canada (August 2024), the US (April 2024),  Australia (July 2022), and Europe (July 2020).

Biocon’s Ustekinumab Biosimilar Approved in Australia

Yesintek® is approved in the US (December 2024), Japan (January 2025), Europe (February 2025), the UK (May 2025) and Canada (October 2025).

New Indication Alert: Shanghai Henlius’ Biosimilar Rituximab Approved in China for Two New Non-Hodgkin’s Lymphoma Indications

On 9 April 2026, Shanghai Henlius Biotech announced that China’s National Medical Products Administration (NMPA) has approved two new non-Hodgkin’s lymphoma indications for Hanlikang® (HLX01), biosimilar to Genentech/Biogen’s Rituxan®/MabThera® (rituximab).

The two new indications are:

  1. in combination with polatuzumab vedotin, cyclophosphamide, doxorubicin, and prednisone for first line treatment of previously untreated adult patients with diffuse large B‑cell lymphoma (DLBCL); and
  2. in combination with bendamustine and polatuzumab vedotin for the treatment of adult patients with relapsed or refractory DLBCL who are not candidates for hematopoietic stem cell transplant.

Rituximab was one of the first mAbs to become “biosimilar”, being first approved in the US on 26 November 1997.  Henlius’ Hanlikang® was the first rituximab biosimilar approved in China in 2019, where its commercial sales are managed by Fosun Pharma.  According to Henlius, Hanlikang® is approved for more indications in China than the reference product (being the only rituximab product approved in China to treat rheumatoid arthritis).

Other rituximab biosimilars approved in China include Innovent/Eli Lilly’s Halpryza® (approved October 2020) and Chia Tai Tianqing’s Delituo® (approved May 2023).

Apotex’s Denosumab Biosimilar Approved in Canada

On 7 April 2026, Apotex announced that Health Canada has approved Denoza™, biosimilar to Amgen’s Prolia® (denosumab), for all indications of the reference biologic.

Sandoz’s Wyost® (approved February 2024) and Jubbonti® (approved March 2024) were the first denosumab biosimilars approved in Canada, and were launched in August 2024. This was followed by the Canadian approvals of Celltrion’s Stoboclo® and Osenvelt® (September 2025) and Henlius/Organon’s Bildyos® and Tuzemty® (HLX14) (March 2026).

Biocon Launches Denosumab Biosimilars in US

On 7 April 2026, Biocon Limited announced that it has launched Bosaya™ and Aukelso™ (denosumab-kyqq), biosimilars to Amgen’s Prolia® and Xgeva®, respectively, in the US.  The launch follows Biocon’s 1 October 2025 settlement and licence agreement with Amgen, which permitted Biocon’s US launch of the biosimilars from 1 October 2025.

Bosaya™ and Aukelso™ received FDA approval in September 2025 and were granted provisional interchangeability designation for all approved indications.

A number of denosumab biosimilars have been approved in the US.  This includes Sandoz’s Jubbonti® and Wyost® (approved March 2024, launched June 2025), Samsung Bioepis’ Obodence™ and Xbryk™ (approved February 2025, to be included on US formularies from 1 April 2026), Celltrion’s Stoboclo® and Osenvelt® (approved March 2025, launched July 2025), Fresenius Kabi’s Conexxence® and Bomyntra® (approved March 2025, launched July 2025), Shanghai Henlius/Organon’s Bildyos® and Bilprevda® (approved September 2025, launched October 2025), Richter/Hikma’s Enoby™ and Xtrenbo™ (approved September 2025; launched January 2026), Accord’s Osvyrti® and Jubereq® (approved November 2025) and Amneal/mAbxience’s Boncresa™ and Oziltus™ (MB09) (approved December 2025).

Outlook Therapeutics Submits Dispute Resolution Request to FDA For Ophthalmic Bevacizumab Following Regulatory Setbacks

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.

CuraTeQ Completes Ph 3 Biosimilar Omalizumab Trial

On 6 April 2026, Aurobindo’s wholly owned subsidiary, CuraTeQ Biologics, announced it has obtained positive top-line results from a Phase 3 study of BP11 (omalizumab, 300 mg), biosimilar to Genentech/Novartis’ Xolair®.

According to CuraTeQ, the study, which was conducted in 608 patients across 80 sites in Europe and India, successfully met all primary endpoints, demonstrating comparable efficacy and safety to Xolair® in patients with chronic spontaneous urticaria at the 300 mg dose.

Buoyed by these results, which follow completion of a Phase 1 study in March 2024, CuraTeQ is planning to complete regulatory filings with both the European Medicines Agency and the FDA by the end of Q2 2026.

Celltrion’s Omlyclo® is currently the only omalizumab biosimilar on the market anywhere in the world.  Omlyclo® has been approved in: the EU (May 2024, with a high dose (300 mg) form approved November 2025); Korea (June 2024, as PFS, with autoinjector approved December 2025; high dose formulation launched 30 March 2026); Australia (November 2024); Canada (December 2024, with a high dose formulation approved January 2026); the US (March 2025, in 75 mg/0.5ml and 150 mg/ml PFS forms, with full interchangeable status, and December 2025 in high dose); New Zealand (April 2025); and Japan (March 2026).  Celltrion commenced its European rollout of Omlyclo® with the launch of the product in Norway in September 2025, and completed its launch in major European countries including Germany, Spain, the UK and France in November 2025.  In late November 2025, Celltrion announced that it launched Omlyclo® in Brazil.

Biosimilar omalizumab is also under development.  Teva announced in March 2026 that its regulatory applications for an omalizumab biosimilar have been accepted for review by the FDA and the European Medicines Agency for all approved reference indications.  On 11 August 2025, Kashiv BioSciences announced that it entered into a licence and supply agreement with Brazilian pharmaceutical company, CRISTÁLIA, for Kashiv’s biosimilar omalizumab, ADL-018, for the Latin American Market.  Kashiv has previously entered into agreements for commercialisation of ADL-018 in other regions, including with MS Pharma for MENA markets (August 2025) and Alvotech for the EU, UK, Australia, Canada and New Zealand (AVT23, October 2023).  A marketing application for AVT23 was accepted by the UK’s MHRA in March 2025 and by the European Medicines Agency in October 2025.

Biocon Joins Alvotech in Filing US PGR Challenging Regeneron’s High Dose Aflibercept Patent

On 2 April 2026, Biocon filed a petition for post grant review (PGR) of Regeneron’s patent US12168036 entitled “Methods for Treating Angiogenic Eye Disorders with High Doses of VEGF Receptor Fusion Proteins”.

Biocon’s petition seeks to join Alvotech’s pending PGR in relation to the same patent.  Alvotech’s PGR petition was filed on 17 September 2025 and the PGR was instituted by the Patent Trial and Appeal Board on 3 March 2026.  Biocon’s PGR petition is substantially the same as that filed by Alvotech.

Regeneron’s ‘036 patent relates to methods for treating an angiogenic eye disorder by intravitreal administration of about 100 microlitres or less of at least about 8mg of a VEGF receptor fusion protein in a formulation with a particular viscosity.  Both Biocon’s and Alvotech’s PGR petitions argue that the claims of the ‘036 patent are invalid for obviousness and lack of written description.

High dose Eylea® is approved in the US (as Eylea HD®) for wet age-related macular degeneration, diabetic macular oedema, diabetic retinopathy (August 2023) and retinal vein occlusion (November 2025).  It is also approved in other jurisdictions (as Eylea™ 8mg), including Europe (January 2026), the UK (February 2026) and Korea (February 2026).  Eylea™ 8mg pre-filled syringe (OcuClick™) was approved in Europe (September 2024), Australia (October 2024) and Korea (August 2025).

Alvotech is developing AVT29, a biosimilar to Regeneron/Bayer’s Eylea HD®.  In June 2024, Alvotech entered into an agreement with Advanz Pharma in relation to the commercialisation of AVT29 in Europe.  Teva holds commercialisation rights for AVT29 (and AVT06, aflibercept 2mg) in the US.  Alvotech has recently indicated that it expects to file the first regulatory submission for AVT29 sometime in 2026.

Biocon has not yet announced that it has a high dose Eylea® biosimilar in development.  Biocon’s Yesafili™ was one of the first approved interchangeable aflibercept (2 mg) biosimilars in the US in May 2024.  Biocon and Regeneron settled US BPCIA litigation regarding aflibercept (2 mg) in April 2025, paving the way for a US launch of Yesafili™ in the second half of 2026, or earlier under certain undisclosed circumstances.

New Indication Alert: MSD’s Keytruda® Approved in EU for Ovarian Cancer

On 2 April 2026, MSD announced that the European Commission has approved Keytruda® (pembrolizumab) in combination with paclitaxel, with or without bevacizumab, for the treatment of platinum resistant epithelial ovarian, fallopian tube, or primary peritoneal carcinoma in adults whose tumours express PDL1 with a CPS ≥ 1 and who have received one or two prior systemic treatment regimens.

The EC approval follows a CHMP positive opinion in February 2026 for the indication, which was also approved by the FDA in February 2026 in both IV (Keytruda®) and subcutaneous (Keytruda Qlex™) formulations.

Pembrolizumab biosimilars have reportedly been launched in Paraguay (by Bioeticos in August 2025) and approved in Vietnam (by Biocad in November 2025).  Pembrolizumab biosimilars are also under development including by Samsung Bioepis, Amgen, mAbxience, Sandoz, Celltrion, Bio-Thera, BioNTechAlvotech and Formycon.

Bayer Reduces Eylea® Price in India by 44%

On 2 April 2026, The Economic Times reported that Bayer has reduced the upfront cost of Eylea® (aflibercept, 2mg) in India by about 44% to expand the eligible patient pool.  According to the report, Eylea® will now be priced at Rs 29,998, down from Rs 53,141.

The announcement comes just under 2 months after Zydus’s Indian launch of its aflibercept biosimilar, Anyra™.  Anyra™ is the first aflibercept 2mg biosimilar developed in India and was launched under licence from Regeneron and Bayer.

There is at least one other aflibercept biosimilar set to launch in India in 2026.  In September 2025, Biocon’s Yesafili® was recommended by India’s Subject Expert Committee (SEC).  This recommendation was subject to Biocon submitting a Phase IV clinical trial protocol to the Central Drugs Standard Control Organisation within 3 months of obtaining the marketing authorisation grant.  In January 2026, Biocon reached a settlement and licence agreement with Regeneron and Bayer for Yesafili® in Europe and ROW, which permits Biocon to commercialise Yesafili® in India (and ROW other than UK, US and Canada) in H2 2026.

Eylea® was jointly developed by Bayer and Regeneron.  Regeneron holds the exclusive rights to Eylea® in the US, while Bayer holds those outside the US, where the companies equally share the profits from sales of the products.

FDA Approves Extended Dosing Interval for Regeneron/Bayer’s Eylea HD®

On 2 April 2026, Regeneron announced that the FDA has approved an extended dosing interval for Eylea HD® (aflibercept 8mg, “high dose”) of up to every 20 weeks for patients with nAMD and diabetic macular oedema (DME), following one year of successful response based on visual and anatomic outcomes.  The new dosing regimen means that nAMD/DME patients can be treated as little as 2-3 times a year.

The approval of the extended dosing regimen is based on 96 week data from the PHOTON and PULSAR trials.  It follows FDA approval of Eylea® HD in November 2025 for RVO with up to 8 weekly dosing after an initial monthly dosing period, and a 4-weekly dosing option for patients who may benefit from resuming this dosing schedule across approved indications (nAMD, DME, DR and RVO).

Regeneron’s pre-filled syringe (PFS) supplementary BLA for Eylea HD® has an FDA target action date in April 2026.  The BLA had been on hold while Regeneron sought to resolve inspection findings at Catalent reported in an October 2025 Complete Response Letter from the FDA.  Catalent (part of Novo Nordisk) is the manufacturer filler included in Regeneron’s sBLA.  Regeneron had planned to submit to the FDA an application to include an alternate PFS manufacturing filler for its Eylea HD® BLA by January 2026.

Eylea HD® (known as Eylea™ 8mg in other jurisdictions), was jointly developed by Bayer and Regeneron.  Regeneron holds the exclusive rights to both 2mg and 8mg Eylea® in the US, while Bayer holds those outside the US, where the companies equally share the profits from sales of the products.

High dose Eylea® is approved for RVO in the US (November 2025), Europe (January 2026), the UK (February 2026) and Korea (February 2026).  It is also approved for nAMD and DME (as intravitreal injection) in those and multiple other countries, including Australia (June 2024).  Eylea™ 8mg pre-filled syringe (OcuClick™) was approved in Europe (September 2024)Australia (October 2024) and Korea (August 2025).

Alvotech is developing AVT29, a biosimilar to Regeneron/Bayer’s Eylea™ 8mg.  In June 2024, Alvotech entered into an agreement with Advanz Pharma in relation to the commercialisation of AVT29 in Europe.  Teva holds commercialisation rights for AVT29 (and AVT06, aflibercept 2mg) in the US.  Alvotech has recently indicated that it expects to file the first regulatory submission for AVT29 sometime in 2026.

Biosimilars of Regeneron/Bayer’s Eylea® (aflibercept, 2mg) are already on the market around the world, including, for example, Alvotech’s Mynzepli® (launched in the UK, Canada and Japan), Amgen’s Pavblu® (available in the US), Sandoz’s Afqlir®/Enzeevu® (launched in the UKAustralia and Canada), Samsung Bioepis’ Afilivu® (available in Korea) and Celltrion’s Eydenzelt® (launched in the UK and Europe).
