Clinically meaningful improvements in enthesitis, dactylitis and physical function with OTEZLA seen at week 16 and were sustained for up to 52 weeks of treatment
PALACE 4 is the first and only large randomized, placebo-controlled study to examine the efficacy and safety of a single agent in patients naïve to previous DMARD therapy
Long-term safety and tolerability profile with OTEZLA consistent with previous PALACE studies
"Physicians need a variety of options to treat psoriatic arthritis, as
treatment is highly individualized and some patients may not be
appropriate candidates for biologics or certain systemic therapies,"
PALACE 4: 52-week Enthesitis and Dactylitis
Results demonstrated that treatment with OTEZLA monotherapy in patients with pre-existing enthesitis (inflammation at sites where tendons or ligaments insert into bone) or dactylitis (a count of fingers and toes with inflammation), two key manifestations of psoriatic arthritis, resulted in long-term improvements. Results were sustained over 52 weeks in patients initially randomized to OTEZLA monotherapy and completing 52 weeks of the study. At week 52, median Maastricht Ankylosing Spondylitis Enthesitis Score (MASES) decreased by 75.0 percent and 45.9 percent of patients receiving OTEZLA 30 mg BID achieved a score of 0, indicating no pain at any of the enthesitis sites assessed. OTEZLA 30 mg BID also resulted in a median 100 percent decrease in dactylitis count. A dactylitis count of 0, indicating no signs of dactylitis, was achieved in 68.8 percent of patients.
PALACE 4: 52-week Physical Function
The results of a physical function analysis from PALACE 4 demonstrated that 52 weeks of treatment with OTEZLA monotherapy resulted in sustained improvements for up to 52 weeks, as measured by validated assessment tools.
In patients who were treated with OTEZLA monotherapy continuously through 52 weeks, clinically meaningful improvements were seen at week 16 in the Health Assessment Questionnaire-Disability Index (HAQ-DI), a key instrument measuring physical function, and improvements were sustained for up to 52 weeks. HAQ-DI measures the difficulty patients have performing activities of daily life such as difficulty dressing, walking and eating.
The HAQ-DI results were further supported by improvements in the short form health survey version 2 Physical Functioning (SF-36 v2 PF) seen in patients who were treated with OTEZLA monotherapy continuously through 52 weeks.
PALACE 4: 52-week Safety and Tolerability
Long-term (52 week) safety results from PALACE 4 identified no new safety findings for OTEZLA compared with the previously reported 24-week safety results. Safety results were consistent with previously reported results from the phase III PALACE 1, 2 and 3 clinical trials.
The majority of adverse events (AEs) were mild or moderate in severity and led to a low rate of discontinuation (5.2 percent in all patients exposed to OTEZLA). The most commonly reported AEs were nausea, diarrhea, headache and upper respiratory tract infection. Nausea and diarrhea were predominantly mild in severity, occurred most frequently in the first two weeks of treatment, and often resolved within a month despite continued treatment and no medical intervention. Serious AEs occurred at low rates, were comparable across treatment groups (0.6 percent OTEZLA 30 mg BID vs. 2.8 percent placebo) and did not increase with long-term OTEZLA exposure. The mean weight loss at the end of the 52 week OTEZLA-exposure period was 1.19 kg in OTEZLA 30 mg BID and 0.91 kg in OTEZLA 20 mg BID.
Similar to other OTEZLA data reported from PALACE 1, 2 and 3, these data do not indicate a need for laboratory monitoring.
About PALACE 4
PALACE 4 is a phase III multi-center, double-blind, placebo-controlled, parallel-group studies with two active-treatment groups. More than 500 DMARD-naïve patients were randomized 1:1:1 to receive either OTEZLA 20 mg BID, 30 mg BID, or identically appearing placebo, for 24 weeks, with a subsequent active treatment phase up to 52 weeks, followed by a long-term safety phase in which all patients are treated with OTEZLA.

OTEZLA is an oral small-molecule inhibitor of phosphodiesterase 4 (PDE4) specific for cyclic adenosine monophosphate (cAMP). PDE4 inhibition results in increased intracellular cAMP levels.
Important Safety Information
OTEZLA® (apremilast) is indicated for the treatment of adult patients with active psoriatic arthritis.
IMPORTANT SAFETY INFORMATION
OTEZLA is contraindicated in patients with a known hypersensitivity to apremilast or to any of the excipients in the formulation.
Warnings and Precautions
Depression: Treatment with OTEZLA is associated with an increase in adverse reactions of depression. During clinical trials, 1.0% (10/998) of patients treated with OTEZLA reported depression or depressed mood compared to 0.8% (4/495) treated with placebo; 0.3% (4/1441) of patients treated with OTEZLA discontinued treatment due to depression or depressed mood compared with none in placebo treated patients (0/495). Depression was reported as serious in 0.2% (3/1441) of patients exposed to OTEZLA, compared to none in placebo treated patients (0/495). Suicidal ideation and behavior were observed in 0.2% (3/1441) of patients on OTEZLA, compared to none on placebo (0/495). Two patients who received placebo committed suicide compared to none on OTEZLA.
Carefully weigh the risks and benefits of treatment with OTEZLA for patients with a history of depression and/or suicidal thoughts/behavior, or in patients who develop such symptoms while on OTEZLA. Patients, caregivers, and families should be advised of the need to be alert for the emergence or worsening of depression, suicidal thoughts or other mood changes, and they should contact their healthcare provider if such changes occur.
Weight Decrease: Body weight loss of 5-10% was reported in 10% of patients taking OTEZLA and in 3.3% of patients taking placebo. Monitor body weight regularly; evaluate unexplained or clinically significant weight loss, and consider discontinuation of OTEZLA.
Drug Interactions: Apremilast exposure was decreased when OTEZLA was
co-administered with rifampin, a strong
Adverse reactions reported in at least 2% of patients taking OTEZLA, that occurred at a frequency at least 1% higher than that observed in patients taking placebo, for up to 16 weeks (after the initial 5-day titration), were (OTEZLA%, placebo%): diarrhea (7.7, 1.6); nausea (8.9, 3.1); headache (5.9, 2.2); upper respiratory tract infection (3.9, 1.8); vomiting (3.2, 0.4); nasopharyngitis (2.6, 1.6); upper abdominal pain (2.0, 0.2).
Use in Specific Populations
Pregnancy and Nursing Mothers: OTEZLA is Pregnancy Category C; it has not been studied in pregnant women. Use during pregnancy only if the potential benefit justifies the potential risk to the fetus. It is not known whether apremilast or its metabolites are present in human milk. Caution should be exercised when OTEZLA is administered to a nursing woman.
Renal Impairment: OTEZLA dosage should be reduced in patients with severe renal impairment (creatinine clearance less than 30 mL/min); for details, see Dosage and Administration, Section 2, in the Full Prescribing Information.

About Psoriatic Arthritis
Psoriatic arthritis is a painful, chronic inflammatory disease characterized by pain, stiffness, swelling and tenderness of the joints, inflammation of specific ligaments and tendons, and decrease in physical functioning. It is estimated that nearly 38 million people worldwide have psoriatic arthritis. Psoriatic arthritis can impact day-to-day activities and has been reported to increase work disability. Common signs and symptoms of psoriatic arthritis include pain, stiffness, and swelling in joints. To learn more about psoriatic arthritis, go to www.discoverpsa.com.
