Updated Safety Recommendation - Abrocitinib should only be used if no suitable treatment alternatives are available in patients: 65 years of age and older, patients with a history of atherosclerotic cardiovascular disease or other cardiovascular risk factors (such as current or past long-time smokers), patients with malignancy risk factors (e.g. current malignancy or a history of malignancy). (Cibinqo Summary of Product Characteristics)
Cibinqo is indicated for the treatment of moderate-to-severe atopic dermatitis in adults and adolescents 12 years and older who are candidates for systemic therapy.1
Laboratory monitoring
Table 1: Laboratory measure and monitoring guidance1
Laboratory measure | Monitoring guidance | Action |
---|---|---|
Complete blood count including Platelet Count, Absolute Lymphocyte Count (ALC), Absolute Neutrophil Count (ANC) and Haemoglobin (Hb) | Before treatment initiation, 4 weeks after initiation and thereafter according to routine patient management. | Platelets: Treatment should be discontinued if platelet counts are < 50 x 103/mm3 |
ALC: Treatment should be interrupted if ALC is < 0.5 × 103/mm3 and may be restarted once ALC returns above this value. Treatment should be discontinued if confirmed. | ||
ANC: Treatment should be interrupted if ANC is < 1 × 103/mm3 and may be restarted once ANC returns above this value. | ||
Hb: Treatment should be interrupted if Hb < 8 g/dL and may be restarted once Hb returns above this value. | ||
Lipid parameters | Before treatment initiation, 4 weeks after initiation and thereafter according to clinical guidelines for hyperlipidaemia. | Patients should be monitored according to clinical guidelines for hyperlipidaemia. |
Haematologic abnormalities
Confirmed ALC < 0.5 × 103/mm3 and platelet count < 50 × 103/mm3 were observed in less than 0.5% of patients in clinical studies. Treatment with Cibinqo should not be initiated in patients with a platelet count < 150 × 103/mm3, an ALC < 0.5 × 103/mm3, an ANC < 1 × 103/mm3 or who have a haemoglobin value < 8 g/dL. Complete blood count should be monitored 4 weeks after initiation of therapy and thereafter according to routine patient management (see Table 1).
Lipids
Dose‑dependent increases in blood lipid parameters were reported in patients treated with abrocitinib compared to placebo. Lipid parameters should be assessed approximately 4 weeks following initiation of Cibinqo therapy and thereafter according to their risk for cardiovascular disease. The effect of these lipid parameter elevations on cardiovascular morbidity and mortality has not been determined. Patients with abnormal lipid parameters should be further monitored and managed according to clinical guidelines, due to the known cardiovascular risks associated with hyperlipidaemia.
Infections/Serious infections
Treatment must not be initiated in patients with an active, systemic infection (contraindication).
Serious infections have been reported in patients receiving Cibinqo. The most frequent serious infections in clinical studies were herpes simplex, herpes zoster and pneumonia.
As there is a higher incidence of infections in the elderly and in the diabetic populations in general, caution should be used when treating the elderly and patients with diabetes. In patients 65 years of age and older abrocitinib should only be used if no suitable treatment alternatives are available.
Risks and benefits of treatment prior to initiating Cibinqo should be considered for patients:
Patients should be closely monitored for the development of signs and symptoms of infection during and after treatment with abrocitinib. A patient who develops a new infection during treatment should undergo prompt and complete diagnostic testing and appropriate antimicrobial therapy should be initiated. The patient should be closely monitored and Cibinqo therapy should be temporarily interrupted if the patient is not responding to standard therapy.
Tuberculosis
Tuberculosis was observed in clinical studies with abrocitinib. Patients should be screened for TB before starting treatment and yearly screening for patients in highly endemic areas for TB should be considered. Abrocitinib must not be given to patients with active TB. For patients with a new diagnosis of latent TB or prior untreated latent TB, preventive therapy for latent TB should be started prior to initiation of Cibinqo.
Viral reactivation
Viral reactivation, including herpes virus reactivation (e.g. herpes zoster, herpes simplex), was reported in clinical studies. The rate of herpes zoster infections was higher in patients who were treated with 200 mg, 65 years of age and older, with a medical history of herpes zoster, with a confirmed ALC <1×103/mm3 prior to the event and patients with severe atopic dermatitis at baseline. If a patient develops herpes zoster, temporary interruption of treatment should be considered until the episode resolves.
Eczema herpeticum (disseminated viral infection mostly due to herpes simplex virus) was also reported in clinical studies with abrocitinib. The condition is characterised by rapid spread of vesicular and erosive lesions, fever and malaise in patients with atopic dermatitis and requires prompt treatment with antiviral agents. Discontinuation or interruption of abrocitinib therapy until the resolution of an eczema herpeticum infection should be considered, depending on the seriousness of the event.
Screening for viral hepatitis should be performed in accordance with clinical guidelines before starting therapy and during therapy with Cibinqo.
Patients with evidence of active hepatitis B or hepatitis C (positive hepatitis C PCR) infection were excluded from clinical studies. Patients who were hepatitis B surface antigen negative, hepatitis B core antibody positive, and hepatitis B surface antibody positive had testing for hepatitis B virus (HBV) DNA. Patients who had HBV DNA above the lower limit of quantification (LLQ) were excluded. Patients who had HBV DNA negative or below LLQ could initiate treatment; such patients had HBV DNA monitored. If HBV DNA is detected, a liver specialist should be consulted.
Vaccination
No data are available on the response to vaccination in patients receiving Cibinqo. Use of live, attenuated vaccines during or immediately prior to Cibinqo therapy should be avoided. Prior to initiating treatment with this medicinal product, it is recommended that patients be brought up to date with all immunisations, including prophylactic herpes zoster vaccinations, in agreement with current immunisation guidelines.
Venous thromboembolism (VTE)
Events of deep venous thrombosis (DVT) and pulmonary embolism (PE) have been reported in patients receiving abrocitinib.
In a large randomised active-controlled study of another JAK inhibitor in rheumatoid arthritis patients 50 years and older with at least one additional cardiovascular risk factor, a dose dependent higher rate of VTE including deep venous thrombosis (DVT) and pulmonary embolism (PE) was observed with the JAK inhibitor compared to TNF inhibitors.
A higher rate of VTE was observed with abrocitinib 200 mg compared to abrocitinib 100 mg.
In patients with cardiovascular or malignancy risk factors abrocitinib should only be used if no suitable treatment alternatives are available.
In patients with known VTE risk factors other than cardiovascular or malignancy risk factors, abrocitinib should be used with caution. VTE risk factors other than cardiovascular or malignancy risk factors include previous VTE, patients undergoing major surgery, immobilisation, use of combined hormonal contraceptives or hormone replacement therapy, inherited coagulation disorder.
Patients should be re-evaluated periodically during abrocitinib treatment to assess for changes in VTE risk.
Promptly evaluate patients with signs and symptoms of VTE and discontinue abrocitinib in patients with suspected VTE, regardless of dose.
Major adverse cardiovascular events (MACE)
Events of MACE have been observed in patients taking abrocitinib.
In a large randomised active-controlled study of another JAK inhibitor in rheumatoid arthritis patients 50 years and older with at least one additional cardiovascular risk factor, a higher rate of major adverse cardiovascular events (MACE), defined as cardiovascular death, non-fatal myocardial infarction (MI) and non-fatal stroke, was observed with the JAK inhibitor compared to TNF inhibitors.
Therefore, in patients 65 years of age and older, patients who are current or past long-time smokers, and patients with a history of atherosclerotic cardiovascular disease or other cardiovascular risk factors, abrocitinib should only be used if no suitable treatment alternatives are available.
Malignancy (excluding non-melanoma skin cancer [NMSC])
Lymphoma and other malignancies have been reported in patients receiving JAK inhibitors, including abrocitinib.
In a large randomised active controlled study of another JAK inhibitor in rheumatoid arthritis patients 50 years and older with at least one additional cardiovascular risk factor, a higher rate of malignancies, particularly lung cancer, lymphoma and non-melanoma skin cancer (NMSC) was observed with the JAK inhibitor compared to TNF inhibitors.
A higher rate of malignancies (excluding non-melanoma skin cancer, NMSC) was observed with abrocitinib 200 mg compared to abrocitinib 100 mg.
In patients 65 years of age and older, patients who are current or past long-time smokers, or with other malignancy risk factors (e.g. current malignancy or a history of malignancy), abrocitinib should only be used if no suitable treatment alternatives are available.
Non-melanoma skin cancers (NMSC)
NMSCs have been reported in patients receiving abrocitinib. Periodic skin examination is recommended for all patients, particularly those who are at increased risk for skin cancer.
Elderly
A total of 176 patients 65 years of age and older were enrolled in Cibinqo studies. The safety profile observed in elderly patients was similar to that of the adult population with the following exceptions: a higher proportion of patients 65 years of age and older discontinued from clinical studies and were more likely to have serious adverse events compared to younger patients; patients 65 years and older were more likely to develop low platelet and ALC values; the incidence rate of herpes zoster in patients 65 years of age and older was higher than that of younger patients. There are limited data in patients above 75 years of age.
Lactose
Patients with rare hereditary problems of galactose intolerance, total lactase deficiency or glucose-galactose malabsorption should not take this medicinal product.
Women of childbearing potential
Women of reproductive potential should be advised to use effective contraception during treatment and for 1 month following the final dose of Cibinqo. Pregnancy planning and prevention for females of reproductive potential should be encouraged.
