Patient's QoL is markedly affected by the persistent disease features of CAPS. Canakinumab treats the underlying causes of CAPS by potent, rapid, and selective blockade of IL-1b. This Phase II, open-label study evaluated the improvement in the HRQoL following canakinumab treatment in CAPS patients.
The study was conducted in CAPS patients with confirmed NLRP3 mutation. Patients received a single dose of canakinumab 150 mg or 2 mg/kg s.c. (patients <=16 yrs) with redosing upon each relapse. HRQoL of adult patients were assessed at baseline and during treatment by patient reported outcomes for fatigue (FACIT-Fatigue©), general mental and physical health (SF-36©), and functional disability (HAQ-DI©). Increases from baseline FACIT-Fatigue and SF-36 scores, and decrease from baseline HAQ-DI scores indicate improvement in HRQoL.
The mean baseline scores for FACIT-Fatigue (31.22) and SF-36 mental (43.02) and physical (37.98) component scores were significantly lower than scores expected in the general population (i.e., 43.6 for FACIT-Fatigue and 50 for both SF-36 component scores, respectively)1,2, confirming the detrimental impact CAPS has on patient's quality of life. HAQ-DI baseline mean score was 0.42 on a scale of 0 (no disability) to 3 (maximum disability). Ten out of 18 patients had functional disability as assessed by HAQ-DI (range 0.13 to 2.5). Canakinumab patients improved their HRQoL scores following a single injection (See Table). Improvements were seen as early as one day after the first single dose and maintained for 5 weeks. FACIT-Fatigue (45.6) as well as SF-36 mental (54.84) and physical component scores (49.52) reached levels comparable to average scores of the general population. Similarly, HAQ-DI improved by 0.2 units 5 weeks after canakinumab administration. HRQoL decreased again prior to canakinumab re-dosing when patients started experiencing a disease flare.
Table. Summary of FACIT-Fatigue, SF-36 and HAQ-DI summary scores by time following a single dose of canakinumab (1st period)
Canakinumab improved the HRQoL in CAPS patients assessed by FACIT- Fatigue, SF-36 mental and physical scores to a level of average scores of the general population and improved functional disability index.
