Olumiant® ▼ (baricitinib): Förekomst av arteriella trombotiska händelser i RA kliniska utvecklingsprogram

Trombos, inklusive DVT, PE, och arteriell trombos (några med dödlig utgång) har förekommit hos patienter som behandlats med baricitinib. Om kliniska funktioner som antyder DVT/PE uppstår bör behandlingen med baricitinib avbrytas.

Arterial Thrombotic Events in the Rheumatoid Arthritis Clinical Development Program

Arterial Thrombotic Event Risk in Patients With Rheumatoid Arthritis

Patients with RA have increased cardiovascular risk, including arterial and venous occlusive events.1-6

Compared with patients without RA, patients with RA have a 1.5 times greater risk of CVD, including

  • myocardial infarction

  • stroke

  • heart failure, and

  • peripheral vascular disease.7

That increased risk exists even in patients without traditional risk factors for CVD such as

  • smoking

  • hypertension

  • diabetes, and

  • hyperlipidemia.7

Exclusion Criteria Potentially Related to Arterial Thrombotic Events in the Baricitinib Clinical Development Program

In the 4 phase 3 BARI clinical trials, RA-BEGIN, RA-BEAM, RA-BUILD, and RA-BEACON, eligibility criteria relating to ATEs excluded patients who

  • have screening electrocardiogram abnormalities that, in the opinion of the investigator or the sponsor, are clinically significant and indicate an unacceptable risk for the patient’s participation in the study, such as Fridericia’s corrected QT interval >500 milliseconds

  • within 12 weeks of study entry have experienced 

    • myocardial infarction

    • unstable ischemic heart disease

    • stroke, or

    • have New York Heart Association stage IV heart failure.8

Incidence of Arterial Thrombotic Events in the Baricitinib Clinical Development Program

Arterial thrombotic events included

  • positively adjudicated cardiovascular events of myocardial infarction and ischemic stroke as well as

  • the following MedDRA preferred terms indicative of ATEs

    • amaurosis

    • cardiac ventricular thrombosis

    • cerebrovascular accident

    • hemiparesis

    • peripheral arterial occlusive disease

    • peripheral artery thrombosis

    • peripheral embolism

    • retinal artery embolism

    • retinal vascular thrombosis

    • transient ischemic attack, and

    • vertebral artery thrombosis.8

The majority of events classified as ATEs were also classified as MACE.8

7-Study Placebo-Controlled Dataset

The 7-study pooled dataset included patients with RA randomized to BARI 4 mg (N=1142, PYE=471.8) or placebo (N=1215, PYE=450.8) from 3 phase 2 studies and 4 phase 3 studies (RA-BEAM, RA-BUILD, RA-BEACON and RA-BALANCE). Patients in the placebo group could have been taking background MTX or other conventional DMARDs. Evaluation time periods included through

  • the 12-week placebo-controlled period in phase 2 studies

  • 16 weeks of assigned treatment before any opportunity for rescue therapy in phase 3 studies, and

  • 24 weeks of assigned treatment or until rescue in phase 3 studies.9

Data from BARI 2 mg (N=479, PYE=185.8) is derived from 4 of these studies in which both BARI 2 mg and BARI 4 mg were options during randomization (2 phase 2 studies as well as RA-BUILD and RA-BEACON).9

Through week 24, TEAEs of ATE were reported for

  • 2 patients in the placebo group (IR=0.4)

  • 2 patients in the BARI 2-mg group (IR=1.0), and

  • 2 patients in the BARI 4-mg group (IR=0.4).8,10

4-Study Extended Dataset

The extended dataset included patients with RA randomized to BARI 4 mg (N=479, PYE=781.1) or BARI 2 mg (N=479, PYE=774.9) from 2 phase 2 and 2 phase 3 studies (RA-BUILD, RA-BEACON) and 1 long term extension study (RA-BEYOND). The evaluation time periods included randomization through last available observation incorporating extension data through 01 September 2019 unless otherwise specified. Data were censored at rescue or dose change.8

Five patients in the BARI 2-mg and 4 patients in the BARI 4-mg group reported an ATE from the 4-study extended dataset. The EAIR was 0.63 and 0.50 for the BARI 2-mg and the BARI 4-mg groups, respectively.8

All BARI RA Dataset

The All BARI RA analysis set included 3770 patients with RA who received BARI at a variety of doses from 1 phase 1, 3 phase 2, and 5 phase 3 studies (RA-BEGIN, RA-BEAM, RA-BUILD, RA-BEACON, RA-BALANCE). Data includes a long-term extension study (RA-BEYOND) with

  • 13,148 PYE,

  • median exposure of 4.2 years,

  • maximum exposure of 8.4 years, and

  • data through 01 September 2019.11,12

At all BARI doses with a maximum exposure of 8.4 years, 69 patients reported an ATE with an IR of 0.52 per 100 PYE.8

This IR of 0.52 is consistent with data presented the previous All BARI RA integrated data with 10,127 total PYE (median 3.1 years, maximum 6.9 years) as depicted over time intervals inFigure 1.8,9

* ATE included positively adjudicated MI and thrombotic stroke, which were also counted as MACE, plus MedDRA preferred terms indicative of other acute ATE; adjudicated in phase 3 for applicable event types.

In an analysis from the All BARI RA integrated dataset with 7,860 total PYE, the incidence of ATE was associated with common risk factors for CVD such as older age, male gender, obesity, hypertension and hypercholesterolemia as shown in Table 1.8,10

Information from the Label

Arterial thrombotic events are not specifically mentioned in the Summary of Product Characteristics, but please note the following related to DVT and PE.13

Events of deep venous thrombosis (DVT) and pulmonary embolism (PE) have been reported in patients receiving baricitinib.13

Baricitinib should be used with caution in patients with risk factors for DVT/PE, such as

  • older age,

  • obesity,

  • a medical history of DVT/PE, or

  • patients undergoing surgery and immobilisation.13

If clinical features of DVT/PE occur, baricitinib treatment should be discontinued and patients should be evaluated promptly, followed by appropriate treatment.13

DVT and PE are listed as uncommon in the table of adverse reactions in the Summary of Product Characteristics.13
