Real-world apremilast use in biologic-naïve psoriatic arthritis patients. Data from Spanish clinical practice.

INTRODUCTION: Apremilast is approved for treatment of psoriasis and psoriatic arthritis (PsA). Real-world evidence on apremilast effectiveness in clinical practice is limited. METHODS: Observational study enrolling adult patients, across 21 Spanish centres, who had initiated apremilast in the prior 6 (±1) months and were biologic naive. Data were collected at routine follow-up visits 6 and 12 months after apremilast initiation. Primary outcome was 6 and 12-month persistence to apremilast. Secondary outcomes included Disease Activity for PsA (DAPSA), joint erosions, enthesitis, dactylitis, and patient-reported quality of life (QoL, measured using the PsA impact of disease [PsAID] questionnaire). RESULTS: We included 59 patients. Most had oligoarticular PsA, moderate disease activity, and high comorbidity burden. Three-quarters were continuing apremilast at 6 months and two-thirds at 12 months; mean (SD) apremilast treatment duration was 9.43 (1.75) months. DAPSA scores showed improved disease activity: one-third of patients in remission or low activity at apremilast initiation versus 62% and 78% at 6 and 12 months, respectively. Eleven of 46 patients with radiographic assessments had joint erosions at apremilast initiation and none at month 12. Median (Q1, Q3) number of swollen joints was 4.0 (2.0, 6.0) at apremilast initiation versus 0.0 (0.0, 2.0) at 12 months. Incidence of dactylitis and enthesitis decreased between apremilast initiation (35.6% and 28.8%, respectively) and month 12 (11.6% and 2.4%, respectively). Over two-thirds of patients had a PSAID-9 score <4 (cut-off for patient-acceptable symptom state) at month 12. CONCLUSIONS: In Spanish clinical practice, two-thirds of PsA patients continued apremilast at 12 months, with clinical benefits at the joint level, no radiographic progression of erosions, and a positive impact on patient-reported QoL. Trial registration number Clinicaltrials.gov: NCT03828045.

Structure-Antitumor Activity Relationships of Aza- and Diaza-Anthracene-2,9,10-Triones and Their Partially Saturated Derivatives.

The 1,8-Diazaanthracene-2,9,10-triones, their 5,8-dihydro derivatives, and 1,8-diazaanthracene-2,7,9,10-tetraones, structurally related to the diazaquinomycin family of natural products, were synthesized in a regioselective fashion employing Diels-Alder strategies. These libraries were studied for their cytotoxicity in a variety of human cancer cell lines in order to establish structure-activity relationships. From the results obtained, we conclude that some representatives of the 1,8-diazaanthracene-2,9,10-trione framework show potent and selective cytotoxicity against solid tumors. Similar findings were made for the related 1-azaanthracene-2,9,10-trione derivatives, structurally similar to the marcanine natural products, which showed improved activity over their natural counterparts. An enantioselective protocol based on the use of a SAMP-related chiral auxiliary derived was developed for the case of chiral 5-substituted 1,8-diazaanthracene-2,9,10-triones, and showed that their cytotoxicity was not enantiospecific.

Recomendaciones de expertos para el uso de apremilast en artritis psoriásica / Expert recommendations for the use of apremilast in psoriatic arthritis

Introducción y objetivos: A pesar de la evidencia, existen dudas sobre el posicionamiento de apremilast en el algoritmo de tratamiento de la artritis psoriásica (APs). El objetivo del presente proyecto fue recoger la evidencia científica y la experiencia de un grupo de reumatólogos expertos en el manejo de la APs sobre el uso de apremilast en la práctica clínica en España. Material y métodos: Un comité científico formado por 6 expertos propuso 5 escenarios clínicos donde la evidencia sobre el uso de apremilast en APs era controvertida: 1) eficacia en APs periférica; 2) eficacia en entesitis y dactilitis; 3) eficacia en APs con afectación cutánea; 4) comorbilidades, y 5) seguridad de apremilast. Tras esto, un panel de 17 reumatólogos expertos en el tratamiento de la APs discutió estos escenarios y generó un cuestionario con 50 preguntas y 156 ítems según metodología Delphi, el cual fue respondido de forma anónima por los panelistas. Resultados: Tras 2 rondas de votación, el panel de expertos alcanzó el consenso en 93 de los 156 ítems planteados (59,6%) (67 apropiados y 26 inapropiados). El grado de consenso fue del 53,3% en el área de «Eficacia en APs periférica»; del 60,0% en «Eficacia en entesitis y dactilitis»; del 50,0% en «Eficacia en APs con afectación cutánea»; del 57,1% en «Manejo de las comorbilidades en pacientes con APs», y del 67,3% en «Implicaciones de la seguridad en el uso de apremilast». Conclusiones: La opinión estructurada de los expertos complementa la evidencia disponible y contribuye al establecimiento de pautas consensuadas para el uso de apremilast en APs.(AU)
