Scientific Name: dupilumab

2025

April 18, 2025

On 18 April 2025, Sanofi and Regeneron announced that Dupixent (dupilumab) received FDA approval as the first new targeted therapy in over a decade for chronic spontaneous urticaria (CSU).  The FDA had accepted Sanofi/Regeneron’s resubmitted supplemental Biologics Licence Application (sBLA) for Dupixent® (dupilumab) for the treatment of CSU in November 2024, with a target action date of 18 April 2025.

Dupixent is already approved for CSU in Japan, the United Arab Emirates, and Brazil.

March 25, 2025

On 28 March 2025, Sanofi and Regeneron announced that Japan’s Ministry of Health, Labour and Welfare has granted marketing and manufacturing authorisation for Dupixent® (dupliumab) for the treatment of chronic obstructive pulmonary disease (COPD) in adults whose disease is not adequately controlled with existing therapy.

Dupixent® was approved in the US and China, and the UK, as an add-on maintenance treatment of adults with inadequately controlled COPD and an eosinophilic phenotype in September 2024.

In July 2024, Dupixent® received European approval as an add-on maintenance treatment for adults with uncontrolled COPD, the first approval of Dupixent® for COPD anywhere in the world.

Australia’s Therapeutic Goods Administration (TGA) has updated its online list of prescription medicines for evaluation for February 2025.  Among the applications to be reviewed is a new indication for MSD’s Keytruda® (pembrolizumab) for patients with head and neck squamous cell carcinoma (HNSCC) as a preliminary treatment prior to surgery or as a treatment in combination with radiotherapy followed by Keytruda® alone.

The TGA has also updated its online list of prescription medicine registrations, with new registrations for the following expanded indications:

  • MSD’s Keytruda® in combination with chemoradiotherapy for treatment of patients with high-risk locally advanced cervical cancer (FIGO 2014 Stage IB1-IIB and node-positive, or Stage III-IVA) (3 March 2025) and in combination with Astellas Pharma’s Padcev® (enfortumab vedotin) for first-line treatment of adults with locally advanced or metastatic urothelial carcinoma (24 February 2025)
  • AstraZeneca’s Imfinzi® (durvalumab) as monotherapy for the treatment of adults with limited stage small cell lung cancer whose disease has not progressed following chemoradiation therapy (27 February 2025);
  • Sanofi’s Dupixent® (dupilumab) for chronic obstructive pulmonary disease (25 February 2025);
  • Astellas’ Padcev® (enfortumab vedotin) as monotherapy for treatment of adults with locally advanced or metastatic urothelial cancer who have previously received a platinum-containing chemotherapy and a programmed death receptor-1 or programmed dealth-ligand-1 inhibitor (17 February 2025); and
  • Bristol-Myers Squibb’s Opdivo® (nivolumab), in combination with chemotherapy, for the neoadjuvant treatment of adults with resectable non-small cell lung cancer and no known EGFR mutations or ALK rearrangements, followed by Opdivo® as a single agent in the adjuvant setting after surgical resection (6 February 2025).

February 18, 2025

On 18 February 2025, Regeneron and Sanofi announced that the US FDA has accepted their sBLA for priority review of Dupixent® (dupilumab) for the targeted treatment of bullous pemphigoid (BP).  The FDA’s decision is expected by 20 June 2025.  If approved, Dupixent® will be the first and only targeted medicine to treat BP in the US.

The FDA is also reviewing a Dupixent® sBLA for chronic spontaneous urticaria (CSU), with action due on 18 April 2025.

Despite the appearance of “business as usual”, Regeneron’s litigation against Sanofi in the US District Court for the Southern District of New York remains on foot, in which Regeneron alleges Sanofi violated the terms of their Dupixent® collaboration agreement.

2024

December 20, 2024

On 20 December 2024, Australia’s Pharmaceutical Benefits Assessment Committee (PBAC) published the outcomes considered at its November 2024 meeting.

The following biosimilars were recommended for listing on the Pharmaceutical Benefits Scheme (PBS):

  • Sandoz’s Wyost®, biosimilar to Amgen’s Prolia® and Xgeva® (denosumab), for osteoporosis, giant cell tumour of bone, and bone metastases
  • Celltrion’s Steqeyma®, biosimilar to Janssen’s Stelara® (ustekinumab), for severe chronic plaque psoriasis, severe psoriatic arthritis, Crohn’s disease, complex refractory fistulising Crohn’s disease, and moderate to severe ulcerative colitis.

Among the originator biopharmaceuticals, Bayer secured a recommendation for its Eylea® (aflibercept) indication expansion for diabetic macular oedema and subfoveal choroidal neovascularisation secondary to age-related macular degeneration.  Novo Nordisk’s Ozempic® (semaglutide) also received a positive recommendation for type 2 diabetes mellitus, following its application for a new strength formulation.

Several oncology treatments received positive recommendations, including Janssen’s Rybrevant® (amivantamab) for non-small cell lung cancer.  Other cancer treatments recommended include Amgen’s Blincyto® (blinatumomab) for MRD-negative B-cell precursor acute lymphoblastic leukaemia, AstraZeneca’s Imfinzi® for use in combination with platinum-based chemotherapy for the treatment of deficient mismatch repair (dMMR) endometrial cancer, and Astellas Pharma’s Padcev® (enfortumab vedotin) for locally advanced or metastatic urothelial cancer.

AbbVie’s Epkinly® (epcoritamab) received a recommendation for relapsed or refractory diffuse large B-cell lymphoma, while Novartis’ Aimovig® (erenumab) was recommended for chronic migraine.

For hereditary angioedema, both CSL’s garadacimab and Takeda’s Takhzyro® (lanadelumab) secured positive recommendations.

Additional recommendations were granted to BMS’s Opdivo® (nivolumab) for urothelial carcinoma, MSD’s Keytruda® (pembrolizumab) for renal cell carcinoma, and Alexion Pharmaceuticals’ Ultomiris® (ravulizumab) for Neuromyelitis Optica Spectrum Disorder.

BeiGene’s Tevimbra® (tislelizumab) also received a positive recommendation for oesophageal squamous cell carcinoma.

The PBAC reports that some earlier recommendations have been extended:

  • Sanofi’s Dupixent® (dupilumab) for chronic severe atopic dermatitis and uncontrolled severe asthma

Additionally, two recommendations have been rescinded:

  • Celltrion Remsima SC® (infliximab) for rheumatoid arthritis
  • AbbVie’s Skyrizi® (risankizumab) for Crohn’s disease

 

December 14, 2024

The Australian Government has reached an agreement with Sanofi and Australia’s Pharmaceutical Benefits Advisory Committee (PBAC) to ensure Dupixent® (dupilumab) remains listed on the Pharmaceuticals Benefits Scheme (PBS) for eczema treatment, as it has been since 2021.  In July 2024, higher than expected prescription numbers had risked Dupixent® being withdrawn from the PBS.  Eczema Support Australia lobbied in support of the continued listing and has welcomed the decision.

Dupixent® will be considered in March 2025 for PBS listing for severe atopic dermatitis and uncontrolled severe asthma.

November 28, 2024

On 28 November 2024, Australia’s Pharmaceutical Benefits Scheme (PBS) published its agenda for the March 2025 Pharmaceutical Benefits Advisory Committee (PBAC) meeting.  This follows the PBAC’s publication of its September 2024 intracycle meeting outcomes, which noted that, to date, it had not received an acceptable proposal for an expanded listing to facilitate broad access to PD-(L)1 inhibitors which includes MSD’s pembrolizumab and BMS’ nivolumab.   

For the March 2025 agenda, half of the submissions selected for consideration are for monoclonal antibodies, 17 of which are list for new PBS additions and 6 for amendments. 

Four biosimilars will be considered for new listings: 

  • Pfizer’s Ixifi®, biosimilar to Janssen’s Remicade® (infliximab), for severe active rheumatoid arthritis, ankylosing spondylitis, severe psoriatic arthritis, severe chronic plaque psoriasis, severe Crohn disease, complex refractory fistulising Crohn Disease, and moderate to severe ulcerative colitis 
  • Sandoz’s Tyruko®, biosimilar to Biogen’s Tysabri® (natalizumab), for relapsing-remitting multiple sclerosis

November 21, 2024

On 21 November 2024, Replimune announced that it has submitted a biologics license application (BLA) to the FDA for RP1 (vusolimogene oderparepvec, a genetically modified oncolytic strain of HSV-1 virus) in combination with Opdivo® (nivolumab) for the treatment of adult patients with advanced melanoma who have previously received an anti-PD1 containing regimen.  The submission was made under the Accelerated Approval pathway.  The Company also announced that the FDA has granted Breakthrough Therapy designation to RP1 in combination with nivolumab in the same setting. 

Opdivo® is was approved in Europe in August 2023 for treatment of melanoma as monotherapy. 

November 18, 2024

Regeneron has sued Sanofi, its partner in the commercialisation of the blockbuster eczema drug Dupixent® (dupilumab), in the US District Court for the Southern District of New York alleging that Sanofi is in breach of its commercialisation agreement.  The issues relate to contracts Sanofi negotiates with intermediaries between drug-makers, pharmacies, and insurance companies.  Regeneron alleges that Sanofi has not allowed it access to the relevant contracts to verify compliance with its profit-sharing arrangement. 

Regeneron and Sanofi have previously been on the same side in dupilumab patent proceedings against Amgen and Immunex.  In that matter, the PTAB denied the institution of a review, deciding that the petitioners had not established a reasonable likelihood that they would prevail in showing the unpatentability of the patent. 

 

November 15, 2024

On 15 November 2024, Regeneron and Sanofi announced that the US FDA has accepted for review their resubmitted supplemental Biologics Licence Application (sBLA) for Dupixent® (dupilumab) for patients aged 12 years and older with chronic spontaneous urticaria (CSU) whose disease is not adequately controlled with H1 antihistamine treatment.  The FDA’s target action date is 18 April 2025.

Regeneron and Sanofi had received a Complete Response Letter from the FDA in October 2023 requiring further efficacy data for the use of Dupixent® for CSU.

The resubmitted sBLA was supported by data from the LIBERTY-CUPID Phase 3 clinical program.  This included a confirmatory phase 3 study of Dupixent® which met the primary and key secondary endpoints for treatment of patients with uncontrolled, biologic-naïve CSU receiving background therapy with antihistamines.

Japan was the first country in the world to approve Dupixent® for CSU in February 2024.

In October 2024, Sanofi reported that sales of Dupixent® for Q3 2024 had increased globally by 24% to €3.5 billion and were expected to total about €13bn for the full year.
