Efficacy and Safety of Juan Bi Pill with Add-on Methotrexate in Active Rheumatoid Arthritis: A 48-Week, Multicentre, Randomized, Double-Blind, Placebo-Controlled Trial.
To explore the efficacy and safety of Juan Bi Pill (JBP) in treatment of active rheumatoid arthritis (RA).
From February 2017 to May 2018, 115 participants from 4 centers were randomly divided into JBP group (57 cases) and placebo group (58 cases) in a 1:1 ratio using a random number table method. Participants received a dose of JBP (4 g, twice a day, orally) combined with methotrexate (MTX, 10 mg per week) or placebo (4 g, twice a day, orally) combined with MTX for 12 weeks. Participants were required with follow-up visits at 24 and 48 weeks, attending 7 assessment visits. Participants were undergo disease activity assessment 7 times (at baseline and 2, 4, 8, 12, 24, 48 weeks) and safety assessments 6 times (at baseline and 4, 8, 12, 24, 48 weeks). The primary endpoint was 28-joint Disease Activity Score (DAS28-ESR and DAS28-CRP). The secondary endpoints included American College of Rheumatology (ACR) criteria for 20% and 50% improvement (ACR20/50), Health Assessment Questionnaire Disability Index (HAQ-DI), clinical disease activity index (CDAI), visual analog scale (VAS), Short Form-36 (SF-36) score, Medial Outcomes Study (MOS) sleep scale score, serum erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), tender joint count, swollen joint count, and morning stiffness. The adverse reactions were observed during the treatment.
After 12 weeks of treatment, DAS28-ESR and DAS28-CRP scores in both groups were lower than before treatment (both P<0.01), while the remission rate of DAS28-ESR and DAS28-CRP and low disease activity of JBP group were higher than those in the placebo group (both P<0.01). JBP demonstrated better efficacy on ACR20 and ACR50 compliance rate at 12 and 48 weeks comparing to placebo (all P<0.05). The CDAI and HAQ-DI score, pain VAS and global VAS change of RA patients and physicians, the serum ESR and CRP levels, and the number of tenderness and swelling joints were lower than before treatment at 4, 8, 12, 24, 48 weeks in both groups (P<0.05 or P<0.01), while the reduction of above indices in the JBP group was more obvious than those in the placebo group at 12 weeks (ESR and CRP, both P<0.05) or at 12 and 48 weeks (all P<0.01). There was no difference in adverse reactions between the 2 groups during treatment (P=0.75).
JBP combined with MTX could effectively reduce disease activity in patients with RA in active stage, reduce the symptoms of arthritis, and improve the quality of life, while ensuring safety, reliability, and fewer adverse effects. (Trial Registration: ClinicalTrials.gov, No. NCT02885597).

Efficacy and safety of filgotinib as induction and maintenance therapy for Crohn's disease (DIVERSITY): a phase 3, double-blind, randomised, placebo-controlled trial.
There is a need for efficacious therapies for patients with Crohn's disease that are better tolerated and more durable than available treatments. We aimed to evaluate the efficacy and safety of filgotinib, an oral Janus kinase 1 preferential inhibitor, for treating Crohn's disease.
This phase 3, double-blind, randomised, placebo-controlled trial was conducted in 371 centres in 39 countries. Eligible patients were aged 18-75 years with moderately to severely active Crohn's disease for at least 3 months before enrolment. Patients were enrolled into one of two induction studies on the basis of their experience with biological agents (induction study A included biologic-naive and later biologic-experienced patients and induction study B included biologic-experienced patients). In both induction studies, patients were randomly assigned (1:1:1), using an interactive web response system, to receive oral filgotinib 200 mg, filgotinib 100 mg, or placebo once daily for 11 weeks. Patients who received filgotinib and had two-item patient-reported outcome (PRO2) clinical remission or an endoscopic response at week 10 were re-randomised (2:1) to receive their induction dose or placebo orally, once daily to the end of week 58 in the maintenance study. Co-primary endpoints were PRO2 clinical remission and an endoscopic response at week 10 (induction studies) and week 58 (maintenance study). PRO2 clinical remission was defined as an abdominal pain subscore of not more than 1 and a liquid or very soft stool frequency subscore of not more than 3 (from eDiary data) and endoscopic response was defined as a reduction of at least 50% in Simple Endoscopic Score for Crohn's disease from induction baseline (from central reading of endoscopy). For the induction studies, efficacy was assessed in all randomly assigned patients who received at least one dose of study drug. For the maintenance study, efficacy was assessed in all patients from either filgotinib treatment group in the induction studies who reached PRO2 clinical remission or an endoscopic response at week 10, and who were re-randomised and received at least one dose of study drug in the maintenance study. Patients who received placebo throughout the induction and maintenance studies were not included in the full analysis set for the maintenance study. Safety was assessed in all patients who received at least one dose of study drug. This trial is complete and is registered with ClinicalTrials.gov, NCT02914561.
Between Oct 31, 2016, and Nov 11, 2022, 2634 patients were screened, of whom 1372 were enrolled (induction study A: n=707, induction study B: n=665, and maintenance study: n=481). There were 346 (49%) women and 358 (51%) men in induction study A, 356 (54%) women and 303 (46%) men in induction study B, and 242 women (51%) and 236 men (49%) in the maintenance study. Significantly more patients had PRO2 clinical remission at week 10 with filgotinib 200 mg than with placebo in induction study B (29·7% vs 17·9%, difference 11·9%; 95% CI 3·7 to 20·2, p=0·0039) but not induction study A (32·9% vs 25·7%, 6·9%; -1·4 to 15·2, p=0·0963); there was no significant difference for endoscopic response (induction study A: 23·9% vs 18·1%, difference 5·5%; 95% CI -2·0 to 12·9, p=0·1365; induction study B: 11·9% vs 11·4%, 0·1%; -6·5 to 6·6, p=0·9797). At week 58, both co-primary endpoints were reported in greater proportions of patients who received filgotinib 200 mg than in those who received placebo (PRO2 clinical remission: 43·8% vs 26·4%, difference 16·8%; 95% CI 2·0 to 31·6, p=0·0382; endoscopic response: 30·4% vs 9·4%, difference 20·6%; 95% CI 8·2 to 33·1, p=0·0038). Co-primary endpoints were not met for filgotinib 100 mg in any study. In the induction studies, the most frequently reported treatment-emergent adverse events (TEAEs; ≥5% of patients in any group) were abdominal pain; arthralgia; an exacerbation, flare, or worsening of Crohn's disease; headache; nasopharyngitis; nausea; and pyrexia. In the maintenance study, the most frequently reported TEAEs (≥5% of patients in any filgotinib or associated placebo group) were those reported in the induction studies (except for headache) and abdominal distension, upper abdominal pain, anaemia, and flatulence. Serious TEAEs were reported in 49 patients in induction study A (18 [8%]) of 222 patients in the filgotinib 200 mg group, 16 [7%] of 245 patients in the filgotinib 100 mg group, and 15 [6%] of 237 patients in the placebo group), 81 patients in induction study B (19 [9%] of 202 patients in the filgotinib 200 mg group, 36 [16%] of 228 patients in the filgotinib 100 mg group, and 26 [11%] of 229 patients in the placebo group), and 49 patients in the maintenance study (13 [11%] of 118 patients in the filgotinib 200 mg-filgotinib 200 mg group, five [9%] of 56 patients in the filgotinib 200 mg-placebo group, 14 [13%] of 104 patients in the filgotinib 100 mg-filgotinib 100 mg group, three [5%] of 55 patients in the filgotinib 100 mg-placebo group, and 14 [10%] of 145 patients in the placebo-placebo group). No deaths were reported during the induction and maintenance studies.
Filgotinib 200 mg did not meet the co-primary endpoints of clinical remission and an endoscopic response at week 10, but did meet the co-primary endpoints at week 58. Filgotinib treatment was well tolerated, and no new safety signals were reported.
