Company profile

Allergy immunotherapy from natural source material to finished medicines

ALK-Abello is a Danish specialist in allergy immunotherapy, medicines made from carefully standardised allergens to change the body's response to a specific trigger over time. Its portfolio includes tablets, injections and drops for respiratory and venom allergies, plus diagnostics, consumer products and emergency adrenaline formats. The group controls an unusual chain from cultivating pollen and other biological materials to clinical development, pharmaceutical production and distribution across 46 markets.

Allergy immunotherapy

The same principle delivered as tablet, injection or drops

ALK uses controlled exposure to a defined allergen to alter the immune response over time. Its formats include clinician-administered injections and sublingual drops or fast-dissolving tablets; marketed tablets cover allergens such as house dust mite, grass, ragweed and Japanese cedar in different countries.

From farm to pharma

Pollen, mites and venom become standardised medicines

Natural starting materials create a manufacturing challenge: biological variation must not become product variation. ALK grows or collects pollen, mites, venom, food proteins and pet dander, then identifies, extracts, purifies and standardises them before formulation. Its US source-material operation spans farms and facilities in Pennsylvania, California and Washington.

Beyond long-term treatment

Diagnosis, daily management and emergency adrenaline

ALK also makes allergen extracts for diagnostic skin-prick testing and operates in consumer allergy care. For acute anaphylaxis, its portfolio spans an adrenaline auto-injector and the ARS-developed neffy nasal spray in markets where ALK holds commercial rights. Following Health Canada's April 2026 approval, ALK launched neffy 2 mg on 5 August for adults and children weighing at least 30 kg; the 1 mg dose for children weighing 15–30 kg remained under Canadian review.

Reach and next research questions

A specialist platform expands into food allergy and data science

ALK reports production in Denmark, France, Spain and the US, offices in more than 20 countries and activity in 46 markets. Its Allergy+ strategy extends respiratory tablets towards food allergy, anaphylaxis and adjacent conditions. Research examples include an investigational peanut SLIT tablet, digital discovery tools and work with McMaster University on IgE memory B cells.

Current 2026 update

What is changing at ALK-Abello in 2026?

By August, ALK's 2026 story had moved from approvals towards launches, reimbursement and pipeline execution. Q2 tablet sales rose 22% to DKK 1,013 million, 56% of revenue, while early neffy revenue remained modest.

The change in one sentence

The portfolio is moving from regulatory milestones to access and execution.

neffy 2 mg has reached ten markets; paediatric tablets are moving through launches and reimbursement decisions; peanut phase 3 planning meets new R&D leadership.

Four lenses on 2026

The same four-quadrant format used in the Company profile.

01 · Rescue treatment

neffy moves from approval into early launches

As of ALK's 20 August Q2 report, the ARS-developed neffy 2 mg nasal spray had launched in ten markets, most recently Canada on 5 August, for adults and children weighing at least 30 kg. Five European launches occurred around quarter-end. The lower-dose 1 mg version for children aged at least four and weighing 15–30 kg was approved in Europe, but its first launches were still expected later in 2026 and it remained under Canadian regulatory review. Q2 neffy revenue increased but stayed modest as reimbursement continued; UK work to convert national approval into regional access is expected to extend beyond 2026. ALK holds commercial rights in defined territories and a US co-promotion role; it did not develop the molecule.

  • Current signal2 mg launched in 10 markets as of 20 August · 1 mg European launches pending · revenue still modest
  • Why it mattersThe anaphylaxis franchise is crossing from regulatory approval into market-by-market execution, where reimbursement and adoption now matter.

  • Canada neffy 2 mg launch ALK · 5 August 2026

02 · Paediatric access

Children's tablets move through launches and NICE final-draft review

At Q2, ALK's house-dust-mite tablet was approved for paediatric use in 36 countries and launched in 22; the tree-pollen tablet was approved for children and adolescents in 20 countries and launched in 13. ALK links the roll-out to new tablet patients and growth. On 14 August, NICE issued Final Draft Guidance recommending ITULAZAX for ages 5–17 with birch-pollen allergy and ACARIZAX for ages 5–11 with house-dust-mite allergy. ALK expected Final Guidance later in August, after which relevant NHS systems would implement it. Direct NICE project pages checked through the cutoff still listed both appraisals as in development, so completed Final Guidance and immediate NHS availability are not assumed.

03 · Pipeline and leadership

Peanut phase 3 planning meets a new Global R&D leader

In ALLIANCE, a phase 2 trial of 150 patients aged 4–65, ALK reported that 49% at the highest dose tolerated 300 mg of peanut protein after 24 maintenance weeks versus 18% on placebo, with no treatment-related anaphylaxis or serious adverse events. The result stays inside that investigational trial. Q2 says phase 3 preparation remains on track for initiation before year-end, subject to final regulatory dialogue on design. Jacob Glenting becomes EVP and head of Global R&D on 1 September, filling a role vacant since February. He moves from portfolio and product strategy after earlier commercial and licensing work involving Torii/Shionogi, Abbott, GenSci and ARS; ALK describes his remit as balancing core innovation with adjacent allergy areas and partnerships.

04 · What to watch

Three questions for the next disclosures

Three near-term events will show whether 2026's approvals convert into durable access and pipeline progress.

  • NICE final guidanceDoes NICE publish Final Guidance for ITULAZAX and ACARIZAX, and how quickly do relevant NHS systems implement it?
  • neffy 1 mg and reimbursementDoes the paediatric dose launch in Europe and clear Canadian review, while reimbursement lifts revenue beyond its current modest level?
  • Peanut phase 3Does regulatory dialogue conclude in time for the trial to begin before year-end under the incoming Global R&D head?
