THU0196 TOFACITINIB IN PATIENTS WITH RHEUMATOID ARTHRITIS AND INDICATIVE OF DEPRESSION AND/OR ANXIETY: A POST HOC ANALYSIS OF PHASE 3 AND PHASE 3B/4 CLINICAL TRIALS

Abstract

Background:Depression/anxiety are common in RA pts. SF-36 MCS ≤38 can identify probable major depressive disorder and/or probable generalised anxiety disorder (pMDD/pGAD) in RA pts. Tofacitinib is an oral JAK inhibitor for the treatment of RA.Objectives:To assess pMDD/pGAD prevalence in the tofacitinib RA program and efficacy by baseline (BL) pMDD/pGAD status.Methods:Data from pts receiving tofacitinib, ADA, or PBO were pooled from 5 Phase (P)3 and 1 P3b/4 trials. Demographics/BL characteristics were reported by BL pMDD/pGAD (SF-36 MCS ≤38, presence; >38, absence). Month (M)3/6/9/12 SF-36 MCS change from BL (Δ) was estimated, and % with pMDD/pGAD reported. M3/6/12 efficacy outcomes compared tofacitinib-treated pts by BL pMDD/pGAD.Results:BL pMDD/pGAD was seen in 44.5% (tofacitinib 5 mg BID), 39.8% (tofacitinib 10 mg BID), 45.4% (ADA 40 mg Q2W) and 39.1% (PBO) of pts. pMDD/pGAD pts had higher BL CRP and worse disability, fatigue, pain and sleep vs pts without. SF-36 MCS increases were greater for tofacitinib vs PBO/ADA (Fig 1a). The % of pts with BL pMDD/pGAD who continued to have pMDD/pGAD reduced over time, and was generally lower for tofacitinib vs PBO/ADA (Fig 1b). Regardless of BL pMDD/pGAD, efficacy was generally similar for tofacitinib 5 mg BID (Table) and 10 mg BID.Conclusion:~40% of RA pts had BL pMDD/pGAD. SF-36 MCS improvements were greater for tofacitinib vs PBO/ADA. With tofacitinib, % of pts with SF-36 MCS ≤38 reduced by ~60% at M12. Tofacitinib efficacy was similar in pts with/without BL pMDD/pGAD. Limitations include using SF-36 MCS to identify probable rather than confirmed MDD or GAD. Future research using gold standard psychiatric interviews to validate use of SF-36 MCS ≤38 is needed.Table.M3/6/12 efficacy with tofacitinib 5 mg BID, by BL pMDD/pGADaSF-36 MCS ≤38SF-36 MCS >38OR (95% CI)P valueACR20 (%)b,cM355.157.90.89 (0.74, 1.08)0.2330M661.762.80.96 (0.79, 1.16)0.6511M1258.458.60.99 (0.80, 1.22)0.9279ACR50 (%)b,cM325.929.20.85 (0.70, 1.03)0.1022M636.038.00.92 (0.76, 1.11)0.3724M1233.834.30.98 (0.80, 1.20)0.8366ACR70 (%)b,cM310.111.00.91 (0.69, 1.18)0.4704M616.516.51.00 (0.79, 1.26)0.9901M1218.317.51.06 (0.83, 1.34)0.6560DAS28-4(ESR)<2.6 (%)b,cM35.47.40.72 (0.49, 1.05)0.0872M65.98.50.68 (0.49, 0.94)0.0199*M128.011.90.64 (0.47, 0.89)0.0073**ΔHAQ-DI, LS meanc,dSF-36 MCS ≤38SF-36 MCS >38Difference (95% CI)P valueM3-0.41-0.430.01 (-0.04, 0.06)0.6008M6-0.49-0.48-0.01 (-0.06, 0.04)0.6617M12-0.52-0.52-0.01 (-0.06, 0.05)0.8475*p<0.05; **p<0.01 Data pooled from 5 P3 and 1 P3b/4 tofacitinib trialsaBL pMDD/pGAD = SF-36 MCS ≤38;bLogistic regression fit;cFor PBO pts advancing to tofacitinib post-M3, only PBO data were included;dMixed-effects linear model fitΔ, change from baseline; ACR, American College of Rheumatology; BID, twice daily; BL, baseline; CI, confidence interval; DAS28-4(ESR), Disease Activity Score in 28 joints, erythrocyte sedimentation rate; HAQ-DI, Health Assessment Questionnaire-Disability Index; LS, least squares; M, month; MCS, Mental Component Summary score; OR, odds ratio; P, Phase; pGAD, probable generalised anxiety disorder; PBO, placebo; pMDD, probable major depressive disorder; pt, patient; RA, rheumatoid arthritis; SF-36, Short Form-36 health surveyAcknowledgments:Study sponsored by Pfizer Inc.
