Efficacy and Safety of a Novel Low-Dose Triple Single-Pill Combination Compared With Placebo for Initial Treatment of Hypertension.
Single-pill combinations of 3 or more low-dose blood pressure (BP)-lowering drugs hold promise for initial or early treatment of hypertension.
We conducted a placebo-controlled trial of a new single-pill combination containing low doses of telmisartan, amlodipine, and indapamide in 2 dose options to assess efficacy and safety.
This international, randomized, double-blind, placebo-controlled, parallel-group trial enrolled adults with hypertension receiving 0 to 1 BP-lowering drugs. After a 2-week placebo run-in during which any BP-lowering medication was stopped, participants were eligible if home systolic BP (SBP) was 130 to 154 mm Hg. Participants were randomized in a 2:2:1 ratio to GMRx2 ¼ dose (telmisartan 10 mg/amlodipine 1.25 mg/indapamide 0.625 mg), GMRx2 ½ dose (telmisartan 20 mg/amlodipine 2.5 mg/indapamide 1.25 mg), or placebo. The primary efficacy outcome was difference in change in home SBP from randomization to week 4, and primary safety outcome was treatment discontinuation due to an adverse event.
From June 14, 2021 to October 18, 2023, a total of 295 participants (mean age: 51 years; 56% female) were randomized and 96% completed the trial. Baseline mean home BP was 139/86 mm Hg and clinic BP was 138/86 mm Hg after placebo run-in. The placebo-corrected least square mean differences in home SBP at Week 4 were -7.3 mm Hg (95% CI: -4.5 to -10.2) for GMRx2 ¼ dose and -8.2 mm Hg (95% CI: -5.2 to -11.3) for GMRx2 ½ dose; reductions for clinic BP were 8.0/4.0 and 9.5/4.9 mm Hg. At Week 4, clinic BP control (<140/90 mm Hg) was 37%, 65%, and 70% for placebo, GMRx2 ¼ dose, and GMRx2 ½ dose, respectively (both doses P < 0.001 vs placebo). Placebo, GMRx2-triple ¼, and GMRx2 ½ treatment discontinuation due to an adverse event occurred in 1 (1.6%), 0, and 6 (5.1%), respectively; out of normal range serum sodium or potassium was observed in 4 (6.3%), 12 (10.6%), and 12 (10.1%), respectively, but no participant had a serum sodium <130/>150 mmol/L or potassium <3.0/>6.0 mmol/L. Serious adverse events were reported by 2 participants in the placebo and GMRx2 ½ groups and none in the GMRx2 ¼ group.
In a population with mild-to-moderate BP elevation, both dose versions of the novel low-dose triple single-pill combination showed good tolerability and clinically relevant BP reductions compared with placebo.

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.

Randomized, Double-Blind, Placebo-Controlled Trial on the Efficacy, Safety and Tolerability of Modified-Release Methylphenidate (MPH-MR) in Chinese Children and Adolescents with Attention-Deficit/Hyperactivity Disorder (ADHD).
The efficacy and safety of modified-release methylphenidate (MPH-MR) in the treatment of attention-deficit/hyperactivity disorder (ADHD) have been shown in both pediatric and adult Caucasian patients. The objective of this study was to assess the efficacy and safety of MPH-MR in Chinese children and adolescents with ADHD.
MICCA was a randomized, double-blind, placebo-controlled trial conducted at 19 sites in China from September 2018 to July 2021. The study enrolled children and adolescents aged 6 to < 18 years with a primary diagnosis of ADHD according to the Diagnostic and Statistical Manual for Mental Disorders, Fifth Edition (DSM-5). Patients were randomized 1:1 to once-daily MPH-MR (10-60 mg) or placebo. The study included an up-titration phase of up to 5 weeks and a dose maintenance phase of 4 weeks. The primary efficacy endpoint was the change in the ADHD Rating Scale-IV (ADHD-RS-IV) total score from baseline to the end of the maintenance phase (EoM). Secondary endpoints included the change from baseline to EoM in Weiss Functional Impairment Rating Scale-Parent Report (WFIRS-P) total score, and Clinical Global Impression-Improvement (CGI-I) scores at EoM. Safety assessments included treatment-emergent adverse events (TEAEs) and vital signs.
A total of 221 patients were randomized (MPH-MR: n = 110; placebo: n = 111). The change in the ADHD-RS-IV total score from baseline to EoM was significantly greater for MPH-MR versus placebo, with a least squares (LS) mean (95% confidence interval [CI]) treatment difference of - 4.6 (- 6.92, - 2.30) (p < 0.001). The mean (95% CI) treatment difference for the WFIRS-P total score change from baseline to EoM also significantly favored MPH-MR over placebo (- 6.46 [- 10.57, - 2.34]; p = 0.002). The CGI-I score at EoM was significantly lower in the MPH-MR group compared to the placebo group (2.2 vs 2.5; p = 0.002). Treatment-emergent adverse events were reported for 74 (67.3%) patients in the MPH-MR group and 55 (49.1%) patients in the placebo group. Most TEAEs were mild to moderate in severity. The most common TEAEs for MPH-MR were decreased appetite, nausea and upper respiratory tract infection. Treatment-emergent adverse events leading to study drug discontinuation/study withdrawal were reported in 4 (3.6%) patients in the MPH-MR group and 1 (0.9%) patient in the placebo group. No clinically relevant changes in vital signs were observed during the study.
Modified-release methylphenidate was superior to placebo in improving ADHD symptoms and functioning in Chinese pediatric patients with ADHD. Modified-release methylphenidate had a good safety and tolerability profile. Trial Registration http://www.chinadrugtrials.org.cn/ Identifier: CTR20180056 (registered on 21 May 2018).
