Cosentyx® (secukinumab): Psoriatic arthritis and axial spondyloarthritis safety profile and side effects
Cosentyx is indicated for the treatment of moderate to severe plaque psoriasis (PsO) in adults, children and adolescents from the age of 6 years who are candidates for systemic therapy; active psoriatic arthritis (PsA) in adult patients (alone or in combination with methotrexate [MTX]) when the response to previous disease-modifying anti-rheumatic drug therapy has been inadequate; active ankylosing spondylitis (AS) in adults who have responded inadequately to conventional therapy; active non-radiographic axial spondyloarthritis (nr-axSpA) with objective signs of inflammation as indicated by elevated C-reactive protein and/or magnetic resonance imaging evidence in adults who have responded inadequately to non-steroidal anti-inflammatory drugs; active moderate to severe hidradenitis suppurativa (HS; acne inversa) in adults with an inadequate response to conventional systemic HS therapy; active enthesitis-related arthritis (ERA) in patients 6 years and older (alone or in combination with MTX) whose disease has responded inadequately to, or who cannot tolerate, conventional therapy; active juvenile psoriatic arthritis (JPsA) in patients 6 years and older (alone or in combination with MTX) whose disease has responded inadequately to, or who cannot tolerate, conventional therapy.1
Cosentyx is intended for use under the guidance and supervision of a physician experienced in the diagnosis and treatment of conditions for which Cosentyx is indicated.1
In Ireland Cosentyx is reimbursed for the following indications: adult plaque psoriasis (PsO); psoriatic arthritis (PsA) and axial spondyloarthritis (axSpA).
Cosentyx has a consistent safety profile across indications, demonstrated by a decade of clinical experience*1,2
*Since first indicated in 2015 for eligible adults with psoriatic arthritis and ankylosing spondylitis.2
1.8 million+ patients treated globally†3
Image
No discontinuations in pooled clinical trial data and RWE due to Candida infections, with all being non-serious and mild to moderate in severity, except four cases in the PsO pool that were considered severe4
Image
No trend towards increased rates of major adverse cardiovascular event (MACE), malignancy or inflammatory bowel disease (IBD) reported in clinical trials or RWE5
Please read the full warnings and precautions (found in the SmPC) when prescribing Cosentyx.
RWE shows a consistent safety profile up to 9 years in adult indications5
No trend towards increased adverse event (AE) rates over time (pooled data; AS, PsA and PsO in a PSUR including exposure in clinical trials and marketing experience).5

Safety considerations and precautions1
Image
Cosentyx is contraindicated in:
Patients with hypersensitivity to active substance or to any of the excipients
Clinically important, active infection, e.g., active tuberculosis
Image
Patients should be evaluated for tuberculosis infection prior to initiating treatment with secukinumab. Secukinumab should not be given to patients with active tuberculosis. In patients with latent tuberculosis, anti‑tuberculosis therapy should be considered prior to initiation of secukinumab as per clinical guidelines. Patients receiving Cosentyx should be monitored for signs and symptoms of active tuberculosis.
Image
Cases of new or exacerbations of inflammatory bowel disease (IBD) have been reported with Cosentyx. Cosentyx is not recommended in patients with IBD. If a patient develops signs or symptoms of IBD or experiences an exacerbation of pre-existing IBD, Cosentyx should be discontinued and appropriate medical management should be initiated.
Image
Cosentyx has the potential to increase the risk of infections. Serious infections have been observed in patients receiving Cosentyx in the post-marketing setting. Caution should be exercised when considering the use of Cosentyx in patients with a chronic infection or a history of recurrent infection. Patients should be instructed to seek medical advice if signs or symptoms suggestive of an infection occur. If a patient develops a serious infection, they should be closely monitored and Cosentyx should not be administered until the infection resolves. Please see the SmPC for full information.
Image
Rare cases of anaphylactic reactions and angioedema have been observed in patients receiving Cosentyx. If an anaphylactic reaction, angioedema or other serious allergic reaction occurs, administration of Cosentyx should be discontinued immediately and appropriate therapy initiated.
Image
The removable needle cap of Cosentyx 150 mg in pre-filled syringe and 150 mg pre-filled pen contains a derivative of natural rubber (latex). Use in latex-sensitive individuals has not been studied and there is therefore a potential risk of hypersensitivity reactions which cannot be completely ruled out.
Image
Women of childbearing potential should use an effective method of contraception during treatment and for at least 20 weeks after treatment. As a precautionary measure, it is preferable to avoid the use of Cosentyx during pregnancy. Because of the potential for adverse reactions in nursing infants from Cosentyx, a decision on whether to discontinue breastfeeding during treatment and up to 20 weeks after treatment, or to discontinue therapy with Cosentyx, must be made, taking into account the benefit of breastfeeding to the child and the benefit of therapy to the woman.
Image
Live vaccinations should not be given concurrently with Cosentyx. Please see the SmPC for full information regarding vaccinations.
Image
Cosentyx was administered concomitantly with methotrexate, sulfasalazine and/or corticosteroids in arthritis studies (including in patients with PsA and AS). Caution should be exercised when considering concomitant use of other immunosuppressants and secukinumab.
Image
Hepatitis B virus (HBV) reactivation can occur in patients treated with Cosentyx. In accordance with clinical guidelines for immunosuppressants, testing patients for HBV infection is to be considered before initiating treatment with Cosentyx. Patients with evidence of positive HBV serology should be monitored for clinical and laboratory signs of HBV reactivation during Cosentyx treatment. If reactivation of HBV occurs while on Cosentyx, discontinuation of the treatment should be considered, and patients should be treated according to clinical guidelines.
