RELIEF: In Behçet’s, apremilast improves oral ulcers for up to 28 weeks

CHICAGO – Apremilast was effective and well tolerated for up to 28 weeks for the treatment of oral ulcers in patients with active Behçet’s disease, based on findings from the randomized, placebo-controlled, phase 3 RELIEF trial.

At baseline, mean oral ulcer counts were 4.2 in 104 patients randomized to receive the oral phosphodiesterase-4 inhibitor and 3.9 in 103 patients in the placebo group. Mean visual analog scale (VAS) pain scores were 61.2 and 60.8 in the two groups, respectively.

The primary study endpoint of area under the curve for total number of oral ulcers over a 12-week period (AUC_Wk0-12) – a measure that reflects the number of oral ulcers that occur over time and also accounts for the recurring-remitting course of oral ulcers – was achieved. AUC_Wk0-12 was significantly lower in the apremilast group than in the placebo group (129.54 vs. 222.14, respectively; P less than .0001), Gulen Hatemi, MD, reported at the annual meeting of the American College of Rheumatology.

From baseline to week 12, apremilast treatment also resulted in a significantly lower number of oral ulcers (mean of 1.1 vs. 2.0 for placebo at 12 weeks) and significantly reduced pain from oral ulcers at every visit from week 1 through week 12 of the study, compared with placebo (mean VAS score change from baseline, –40.7 vs. –15.9), said Dr. Hatemi, a professor of medicine at Istanbul University.

“The [12-week] complete response rate ... was 53% in the apremilast group and 22.3% in the placebo group. The [12-week] partial response rate ...was 76% in the apremilast group and 48% in the placebo group,” she said, adding that the efficacy of apremilast was sustained with continued treatment through 28 weeks.

Study participants were adults (mean age, 40 years) with active Behçet’s disease and three or more oral ulcers at randomization or two or more at screening and at randomization. All had been previously treated with at least one nonbiologic medication for oral ulcers and were allowed to have received previous biologic therapies for other disease manifestations. Those with active major organ involvement were excluded.

Treatment included a 30-mg dose of apremilast twice daily for 12 weeks or placebo. After 12 weeks, all patients received apremilast through at least 28 weeks of the 64-week study.

At the 28-week analysis, patients who were initially randomized to placebo and who switched to apremilast after week 12 had benefits comparable with those seen in those randomized to apremilast at the start of the study. A complete response was seen in 59% and 62% of patients in the groups, respectively, and a partial response was seen in 90% and 85%, respectively. Additionally, the mean change in the VAS score for oral ulcer pain in the groups at that time was –40.6 and –41.9, Dr. Hatemi said.

Apremilast was well tolerated in this study; the incidence of adverse events was comparable in the treatment and placebo groups during the 12-week placebo-controlled phase of the study – 78.8% and 71.8%, respectively. The most common events were diarrhea, nausea, headache, and upper respiratory tract infection, she said.

“These were generally mild to moderate, and only two patients had to discontinue the study due to gastrointestinal adverse events,” she said, noting that no new safety signals were observed.

Behçet’s disease is a chronic, relapsing, multisystem inflammatory disorder characterized by recurrent oral ulcers that can be disabling and have a substantial effect on quality of life. These findings, which include efficacy data up to 28 weeks and safety data for at least 100 patients exposed to apremilast for at least 1 year, demonstrate the efficacy of apremilast for the treatment oral ulcers in patients with Behçet’s disease, she said, noting that “the safety findings were consistent with the known safety profile of apremilast.”

The RELIEF study was supported by Celgene. Dr. Hatemi reported receiving grant/research support from Celgene and serving as a speaker for AbbVie, Mustafa Nevzet Pharmaceuticals, and UCB.
