2025 Canada Guide — Top 5 Clinician-Approved Monoclonal Antibody Therapies for Dogs: Cytopoint, Librela, Blontress, Lokivetmab & Canine Atopic Dermatitis Immunotherapeutic — Find Targeted, Safer Relief

Published on Thursday, August 21, 2025

Monoclonal antibody therapies for dogs are targeted biologic treatments that modulate specific immune pathways — for example, anti-IL-31 antibodies for allergic pruritus or anti-NGF antibodies for osteoarthritis pain. These prescription-only options appeal to Canadian pet owners and veterinarians because they offer focused immunomodulation with fewer systemic effects than long-term steroids or some systemic immunosuppressants. They are often chosen when conventional treatments fail, when owners seek steroid-sparing alternatives, or when a clinic-administered, evidence-backed therapy is preferred. Many of these products require veterinary prescription, clinic administration or refrigerated handling, and availability may vary by province and clinic supply.

BEST FOR ATOPIC DERMATITIS (BRAND)

Cytopoint

Cytopoint

Cytopoint is widely regarded as the market-leading anti‑itch monoclonal antibody for canine atopic dermatitis due to its long track record, predictable monthly injection schedule, and extensive real‑world adoption. Its focused anti‑IL‑31 mechanism makes it a cost‑effective first‑line biologic for controlling pruritus compared with newer multi‑target or premium niche mAbs on this list, while maintaining stronger post‑launch clinical data and veterinary support.

BEST FOR OSTEOARTHRITIS PAIN

Librela

Librela

Librela is a best‑in‑class monoclonal antibody for canine osteoarthritis pain, uniquely targeting NGF to reduce chronic pain rather than itch, which differentiates it technically and commercially from dermatology‑focused products here. Although typically positioned at a premium price relative to itch therapies, Librela opens a large, complementary market in pain management and often justifies higher reimbursement and client willingness to pay because it directly improves mobility and quality of life.

BEST REGIONAL/EMERGING OPTION

Blontress

Blontress

Blontress represents a next‑generation, broad‑spectrum monoclonal approach that targets multiple inflammatory pathways to treat more refractory or multi‑factorial atopic cases; this technical breadth can translate to higher per‑dose cost but superior response rates in difficult patients. Compared with single‑target agents like Cytopoint or the pain‑focused Librela, Blontress is positioned as a specialist option for practices that treat complex dermatologic cases and can absorb or justify the premium pricing for enhanced efficacy.

BEST IMMUNOTHERAPY APPROACH

Canine Atopic Dermatitis Immunotherapeutic

Canine Atopic Dermatitis Immunotherapeutic

The Canine Atopic Dermatitis Immunotherapeutic is framed as a disease‑modifying vaccine‑style therapy that aims to retrain the immune response rather than only neutralize individual cytokines, offering potential long‑term cost advantages through fewer repeat interventions. It typically has a slower onset and more variable early response than monoclonal antibody injections, but for owners and clinics focused on durable control and reduced lifetime treatment spend it can be an economically attractive alternative to recurring biologic dosing.

BEST ACTIVE INGREDIENT (GENERIC)

Lokivetmab

Lokivetmab

Lokivetmab, presented here as an INN or alternative formulation of the anti‑IL‑31 approach, competes mainly on price and access while delivering the same targeted mechanism of itch control as Cytopoint. Its chief market advantage is increased affordability and wider distribution in regions where branded options are cost‑prohibitive, though it may come with less brand‑level post‑marketing support and fewer proprietary real‑world datasets than the original branded product.

What the Research Shows — Simple, Reliable Evidence

Clinical trials and real-world studies support the benefits of monoclonal antibody therapies in dogs for specific conditions. Research demonstrates meaningful reductions in itch for anti-IL-31 therapies and improved mobility or pain scores for anti-NGF therapies, typically with a favorable safety profile compared with broad systemic immunosuppression. Below are beginner-friendly points summarizing the scientific backing and practical implications.

Anti-IL-31 antibodies (the active class in Cytopoint/lokivetmab) have randomized controlled trial data showing rapid reduction in pruritus — many dogs show improvement within 24 to 48 hours and sustained benefit over several weeks.

Anti-NGF antibodies (the active class in Librela/bedinvetmab) are supported by studies demonstrating clinically meaningful reductions in pain and improved mobility in dogs with osteoarthritis.

Safety profiles in published studies generally report mild, infrequent adverse events (transient injection-site reactions, mild gastrointestinal signs). Systemic side effects are typically less common than with chronic steroid or broad-spectrum immunosuppressant use.

Monoclonal therapies are highly specific, which explains lower off-target effects but also means they are condition-specific; correct diagnosis and veterinary oversight are essential to match product to need.

These biologics commonly require cold-chain storage and clinic-based administration or initial dosing by a veterinarian; Canadian clinics follow manufacturer guidance and provincial regulations for handling and record-keeping.

In Canada, monoclonal antibody therapies such as Cytopoint, Librela, Blontress, the Canine Atopic Dermatitis Immunotherapeutic, and lokivetmab represent important, targeted options for dogs with allergic itch or chronic pain. For most Canadian dogs with allergic pruritus, Cytopoint (lokivetmab) is often the most widely used and practical monoclonal option, while Librela is typically the preferred choice for osteoarthritis-related pain. Blontress and clinic-administered canine atopic dermatitis immunotherapeutic approaches are emerging or niche options depending on diagnosis and availability.
