Taltz® (ixekizumab): Komorbiditeter i kliniska fas 3-prövningar med psoriasisartrit

Komorbiditeter som rapporterats hos minst 5% av patienterna från SPIRIT-P1 och SPIRIT-P2 tillhandahålls nedan.

Psoriatic Arthritis Clinical Trials

Within the ixekizumab PsA phase 3 clinical development program, comorbidities (reported as preexisting conditions) that were reported in at least 5% of patients at baseline from either SPIRIT-P1 or SPIRIT-P2 are listed in Table 1.

SPIRIT-P1 is a study assessing efficacy and safety of ixekizumab compared to placebo in patients with active PsA who are naive to bDMARDs.1

SPIRIT-P2 is a study assessing efficacy and safety of ixekizumab compared to placebo in patients with active PsA who had inadequate response or intolerance to TNF-inhibitors.2

In ixekizumab clinical trials, patient comorbidities were required to be controlled so as not to pose an unacceptable risk to a patient if participating in the study.

Patients were excluded if they had the presence of significant uncontrolled disorders at screening that, in the opinion of the investigator, posed an unacceptable risk, such as

  • cerebro-cardiovascular

  • respiratory

  • hepatic

  • renal

  • gastrointestinal

  • endocrine

  • hematologic

  • neurologic, or

  • neuropsychiatric.1,2

The individual phase 3 clinical trials were not designed to detect differences in the efficacy and safety of ixekizumab for the treatment of active PsA in patients with or without specific comorbidities.

Note: Drug hypersensitivity, while not generally considered to be a comorbidity, was reported as a preexisting condition in 10% of patients from SPIRIT-P1 and 11% of patients from SPIRIT-P2 at baseline.

a Reported as preexisting conditions at baseline of the clinical trials.

b Consists of patients across all treatment arms combined.

A recent registry study in Denmark found that compared to a reference population, patients with PsA have a higher prevalence of

  • cardiovascular disease (15.5% vs 8.7%)

  • alcohol abuse (1.8% vs 1.4%)

  • smoking (16.3% vs 9.9%), and

  • hypertension (21.2% vs 12.1%).4

The study also found that there was an increased risk of MI associated with longer duration of PsA (HR = 1.02 for each additional year after PsA diagnosis, adjusted for age, sex, socio-economic status, cholesterol-lowering drugs, smoking, alcohol abuse, diabetes, hypertension and previous cardiovascular disease).4

Background information regarding Psoriatic Arthritis Clinical Trials

Psoriatic arthritis

The safety and efficacy of ixekizumab were assessed in two randomised, double-blind, placebo-controlled phase III studies in 780 patients with active psoriatic arthritis (≥3 swollen and ≥3 tender joints). Patients in these studies had a diagnosis of psoriatic arthritis (Classification Criteria for Psoriatic Arthritis [CASPAR] criteria) for a median of 5.33 years. Randomised patients also had current plaque psoriasis skin lesions (94.0%) or a documented history of plaque psoriasis, with 12.1% of patients with moderate to severe plaque psoriasis at baseline. Over 58.9% and 22.3% of the psoriatic arthritis patients had enthesitis and dactylitis at baseline, respectively. For both studies, the primary endpoint was American College of Rheumatology (ACR) 20 response at Week 24.5

Therapeutic Indication

Ixekizumab, alone or in combination with methotrexate, is indicated for the treatment of active psoriatic arthritis in adult patients who have responded inadequately to, or who are intolerant to one or more disease-modifying anti-rheumatic drug (DMARD) therapies.5
