Early and sustained efficacy with apremilast monotherapy in biological-naĂŻve patients with psoriatic arthritis: a phase IIIB, randomised controlled trial (ACTIVE)
Trial registration number NCT01925768[Abstract] Objective Evaluate apremilast efficacy across various psoriatic arthritis (PsA) manifestations beginning at week 2 in biological-naĂŻve patients with PsA.
Methods Patients were randomised (1:1) to apremilast 30 mg twice daily or placebo. At week 16, patients whose swollen and tender joint counts had not improved by ≥10% were eligible for early escape. At week 24, all patients received apremilast through week 52.
Results Among 219 randomised patients (apremilast: n=110; placebo: n=109), a significantly greater American College of Rheumatology 20 response at week 16 (primary outcome) was observed with apremilast versus placebo (38.2% (42/110) vs 20.2% (22/109); P=0.004); response rates at week 2 (first assessment) were 16.4% (18/110) versus 6.4% (7/109) (P=0.025). Improvements in other efficacy outcomes, including 28-joint count Disease Activity Score (DAS-28) using C reactive protein (CRP), swollen joint count, Health Assessment Questionnaire-Disability Index (HAQ-DI), enthesitis and morning stiffness severity, were observed with apremilast at week 2. At week 16, apremilast significantly reduced PsA disease activity versus placebo, with changes in DAS-28 (CRP) (P<0.0001), HAQ-DI (P=0.023) and Gladman Enthesitis Index (P=0.001). Improvements were maintained with continued treatment through week 52. Over 52 weeks, apremilast’s safety profile was consistent with prior phase 3 studies in psoriasis and PsA. During weeks 0–24, the incidence of protocol-defined diarrhoea was 11.0% (apremilast) and 8.3% (placebo); serious adverse event rates were 2.8% (apremilast) and 4.6% (placebo).
Conclusions In biological-naĂŻve patients with PsA, onset of effect with apremilast was observed at week 2 and continued through week 52. The safety profile was consistent with previous reports
Long-Term Safety and Tolerability of Apremilast Versus Placebo in Psoriatic Arthritis: A Pooled Safety Analysis of Three Phase III, Randomized, Controlled Trials.
OBJECTIVE: Psoriatic arthritis (PsA) requires long-term treatment, yet safety concerns and monitoring requirements make maintenance a challenge. This analysis of pooled Psoriatic Arthritis Long-term Assessment of Clinical Efficacy (PALACE) 1, 2, and 3 data describes 3-year apremilast safety and tolerability in PsA.
METHODS: Patients with active PsA were randomized (1:1:1) to placebo, apremilast 30 mg twice daily, or apremilast 20 mg twice daily. Placebo patients were re-randomized to apremilast 30 mg twice daily or 20 mg twice daily at week 16 (early escape) or 24. Double-blind treatment continued to week 52; patients could continue apremilast during an open-label, long-term treatment phase.
RESULTS: In total, 1493 patients received at least one dose of study medication and were included in the safety population (placebo: n = 495; apremilast 30 mg: n = 497; apremilast 20 mg: n = 501). Among patients receiving apremilast, 53.2% (767/1441) completed 3 years of treatment. Greater rates of adverse events (AEs) were reported with apremilast (61.1%; exposure-adjusted incidence rate [EAIR]/100 patient-years, 265.1) versus placebo (47.5%; EAIR/100 patient-years, 200.7) in the placebo-controlled period. During weeks 0 to ≤52, the most common AEs occurring in apremilast-exposed patients were diarrhea (13.9%; EAIR/100 patient-years, 18.6), nausea (12.3%; EAIR/100 patient-years, 16.0), headache (9.4%; EAIR/100 patient-years, 12.1), upper respiratory tract infection (9.1%; EAIR/100 patient-years, 11.5), and nasopharyngitis (6.2%; EAIR/100 patient-years, 7.7). Most AEs were mild/moderate with apremilast exposure ≤156 weeks. Rates of depression remained low (EAIR/100 patient-years, 1.8). Major adverse cardiac events (EAIR/100 patient-years, 0.5), malignancies (EAIR/100 patient-years, 0.9), and serious opportunistic infections (EAIR/100 patient-years, 0.0) were infrequent over the 3-year exposure period. Discontinuation rates due to AEs were low (
CONCLUSION: Apremilast demonstrated a favorable safety profile and was well tolerated up to 156 weeks
Long-term experience with apremilast in patients with psoriatic arthritis: 5-year results from a PALACE 1–3 pooled analysis
Background
The efficacy and safety of apremilast were assessed in patients with psoriatic arthritis (PsA) in three phase III clinical trials with similar designs (PALACE 1, 2, and 3).
Methods
Following a 24-week, randomized (1:1:1 to apremilast 30 mg twice daily, 20 mg twice daily, or placebo), double-blind phase and a 28-week blinded active treatment phase, patients could receive apremilast in open-label extension studies for an additional 4 years. Eligible adult patients had active PsA for ≥ 6 months and three or more swollen joints and three or more tender joints despite prior treatment with disease-modifying anti-rheumatic drugs.
Results
A total of 1493 randomized patients received one or more doses of study medication (placebo: n = 496; apremilast 30 mg twice daily: n = 497; apremilast 20 mg twice daily: n = 500). In patients continuing apremilast treatment, response was sustained without new safety issues. At week 260, 67.2% of remaining patients achieved an ACR20 response, and 44.4% and 27.4% achieved ACR50 and ACR70 responses, respectively. Among patients with baseline enthesitis and dactylitis, 62.4% achieved a Maastricht Ankylosing Spondylitis Enthesitis Score of 0 and 80.9% achieved a dactylitis count of 0, respectively. In patients who had ≥ 3% baseline psoriasis body surface area involvement, 43.6% achieved ≥ 75% reduction from the baseline Psoriasis Area and Severity Index scores. The most commonly reported adverse events (AEs) were diarrhea, nausea, headache, upper respiratory tract infection, and nasopharyngitis, with most diarrhea and nausea AEs occurring within the first 2 weeks of treatment and usually resolving within 4 weeks. Reported rates of depression during the study were low (≤ 1.8%). The majority of patients maintained their weight within 5% of baseline during the study. No new safety concerns or increases in the incidence or severity of AEs were observed over the long term.
Conclusions
Apremilast maintained clinical benefit and a favorable safety profile for up to 5 years among patients with PsA.

Can Circulating Cell-Free DNA or Circulating Tumor DNA Be a Promising Marker in Ovarian Cancer?
In recent years, the studies on ovarian cancer have made great progress, but the morbidity and mortality of patients with ovarian cancer are still very high. Due to the lack of effective early screening and detecting tools, 70% of ovarian cancer patients are diagnosed at an advanced stage. The overall survival rate of ovarian cancer patients treated with surgical combined with chemotherapy has not been significantly improved, and they usually relapse or resist chemotherapy. Therefore, a novel tumor marker is beneficial for the diagnosis and prognosis of patients with ovarian cancer. As the index of “liquid biopsy,” circulating cell-free DNA/circulating tumor DNA (cfDNA/ctDNA) has attracted a lot of attention. It has more remarkable advantages than traditional methods and gives a wide range of clinical applications in kinds of solid tumors. This review attempts to illuminate the important value of cfDNA/ctDNA in ovarian cancer, including diagnosis, monitoring, and prognosis. Meanwhile, we will present future directions and challenges for detection of cfDNA/ctDNA
