What can replace Cosentyx (secukinumab) for plaque psoriasis or psoriatic arthritis?
Cosentyx is a biologic antibody that blocks interleukin-17A (IL‑17A). Alternatives usually fall into two buckets: other IL‑17 blockers (closest mechanism) or different immune targets (when a change is needed because of response, side effects, coverage, or convenience).
Other IL‑17A/IL‑17 pathway options
Patients switching within the IL‑17 pathway often consider:
- Ilumya (tildrakizumab) and other IL‑23 inhibitors are sometimes used instead when an IL‑17 switch is not desired, but they do not target IL‑17A specifically.
- Other IL‑17 drugs may be considered depending on availability and the specific diagnosis (plaque psoriasis vs psoriatic arthritis vs ankylosing spondylitis).
If you tell me which condition you’re treating (plaque psoriasis, psoriatic arthritis, ankylosing spondylitis, or non-radiographic axial spondyloarthritis), I can narrow the list to the more typical substitutes.
If you want the closest “same type” alternative, which IL‑17 drugs are comparable?
Because Cosentyx works via IL‑17A, a “closest” alternative is generally another IL‑17 pathway biologic rather than an IL‑12/23, IL‑23, TNF, or JAK pathway drug. The exact best match depends on:
- Your diagnosis
- Past biologic exposure and what failed (primary non-response vs loss of response)
- Whether you have a history of recurrent infections, inflammatory bowel disease, or other contraindications
What if you’re switching because Cosentyx isn’t working—what targets get used next?
If Cosentyx doesn’t control symptoms, clinicians commonly switch to a different class, such as:
- IL‑23 inhibitors (often used for plaque psoriasis and sometimes selected spondyloarthritis cases depending on guidelines/approval)
- TNF inhibitors (another well-established option across psoriatic disease)
- JAK inhibitors for certain indications (oral option; selection depends on diagnosis and risk factors)
Oral vs injection: are there alternatives to Cosentyx that don’t require biologic infusions/injections?
Yes—some targeted oral therapies exist for certain inflammatory arthritis/psoriatic disease indications, but suitability depends on the exact diagnosis and your health history. Many “true alternatives” to Cosentyx for psoriasis/psoriatic arthritis are still injections (biologics), but there are cases where an oral option is appropriate.
What do patients usually consider when switching from Cosentyx?
Common reasons people look for an alternative medication include:
- Not enough symptom control
- Side effects or lab changes
- Frequent dosing burden
- Insurance coverage changes
- Preference for a different administration schedule or a different risk profile
A switch plan also depends on whether the new medication can be started right away or whether there’s a washout period.
How do biosimilars factor in?
In many markets, biosimilars to secukinumab (Cosentyx) can reduce cost and improve access, while keeping the same target (IL‑17A). Whether a biosimilar is available to you depends on country and payer rules.
If you share your country, I can point you to the most relevant Cosentyx biosimilar or next-best options.
Does patent status affect whether cheaper alternatives are available?
Patent and exclusivity status can affect when lower-cost biosimilars or competitors enter the market.

Quick questions so I can recommend the right “alternative”
1) What are you treating: plaque psoriasis, psoriatic arthritis, ankylosing spondylitis, or something else?
2) Are you switching because of lack of response or side effects?
3) What country are you in (affects what options are available)?
4) Have you tried any other biologics before Cosentyx?
