American journal of ophthalmology. 2021;:382-387
Abstract
PURPOSE To assess whether prophylactic use of netarsudil 0.02% ophthalmic solution reduces the risk of intraocular pressure (IOP) elevation associated with prolonged use of topical corticosteroids to prevent cornea transplantation rejection. DESIGN Prospective, randomized clinical trial. METHODS In this study, 120 subjects were randomized to use netarsudil (off-label) or placebo once daily for 9 months after Descemet membrane endothelial keratoplasty, and 71 fellow eyes were enrolled and assigned to the opposite treatment arm. Participants concurrently used topical prednisolone acetate 1% 4× daily for 3 months, 3× daily for a month, twice daily for a month, and once daily for 4 months. The main outcome was IOP elevation (defined as IOP ≥24 mm Hg or an increase of ≥10 mm Hg over baseline) assessed by Kaplan-Meier and proportional hazards analyses, taking loss to follow-up into consideration. RESULTS Overall, 95 eyes were assigned to netarsudil and 96 to placebo; 15 eyes (16%) were withdrawn early from the netarsudil arm because of ocular irritation. The rate of IOP elevation was 14% with netarsudil and 21% with placebo (relative risk: 0.6; 95% confidence interval: 0.3-1.3; P = .23). IOP was >30 mm Hg in 7.8% assigned to netarsudil versus 7.4% assigned to placebo (P = .84). Median 6-month central endothelial cell loss was 31% versus 29% with netarsudil versus placebo, respectively (P = .49). CONCLUSIONS Netarsudil did not produce a statistically significant reduction in the risk of steroid-induced IOP elevation after corneal transplantation relative to placebo.

Abstract
PURPOSE Intraocular pressure (IOP) reduction is key to controlling primary open angle glaucoma (POAG). Pharmacotherapies for POAG or ocular hypertension (OHT) commonly lower IOP by increasing uveoscleral outflow or decreasing aqueous humor production. Netarsudil (Rhopressa), a Rho kinase inhibitor, reduces IOP by improving trabecular outflow facility, which is reduced in POAG. We investigated the effects of netarsudil on aqueous humor dynamics in patients with POAG or OHT. DESIGN Double-masked, randomized, vehicle-controlled, Phase 2 trial. METHODS Netarsudil 0.02% was instilled in 1 eye and vehicle into the contralateral eye of 20 patients once daily in the morning for 7 days. The primary endpoint was change in mean diurnal outflow facility on day 8 versus that on day 1 (baseline). Outflow facility was measured by using Schiøtz tonography, IOP by pneumotonometry, and episcleral venous pressure (EVP) by automated venomanometry. RESULTS Eighteen patients (90%) completed the study. Mean diurnal outflow facility increased 0.039 versus 0.007 µL/min/mm Hg from baseline in the netarsudil- and the vehicle-treated groups, respectively (P < .001 vs. baseline for netarsudil), a treatment difference of 0.03 µL/min/mm Hg (P ≤ .001). Mean diurnal IOP change from baseline at day 8 was -4.52 mm Hg for netarsudil versus -0.98 mm Hg for vehicle, a treatment difference of -3.54 mm Hg (P < .0001). Mean diurnal EVP change from baseline was -0.79 mm Hg in the netarsudil-treated group versus 0.10 mm Hg for vehicle, a treatment difference of -0.89 mm Hg (P < .001). All patients reporting an adverse event reported conjunctival hyperemia of mild or moderate severity. CONCLUSIONS Netarsudil acts on the conventional outflow pathway, both proximal and distal, to significantly reduce IOP in POAG and OHT by improving trabecular outflow facility and decreasing EVP.

Abstract
Between April 2004 and December 2010, we conducted a prospective randomized controlled study comparing tamibarotene with all-trans retinoic acid (ATRA) in the maintenance therapy of newly diagnosed acute promyelocytic leukemia (APL), and here report the final results of this study with a median follow-up of 7.3 years. Of 344 eligible patients who had received ATRA and chemotherapy, 319 (93%) achieved complete remission (CR). After completion of three courses of consolidation chemotherapy, 269 patients in molecular remission underwent maintenance randomization, 135 to ATRA (45 mg/m2 daily), and 134 to tamibarotene (6 mg/m2 daily) for 14 days every 3 months for 2 years. The primary endpoint was relapse-free survival (RFS). The 7-year RFS was 84% in the ATRA arm and 93% in the tamibarotene arm (p = 0.027, HR = 0.44, 95% CI, 0.21 to 0.93). The difference was prominent in high-risk patients with initial leukocytes ≥ 10.0 × 109/L (62% vs. 89%; p = 0.034). Tamibarotene was significantly superior to ATRA by decreasing relapse in high-risk patients. Overall survival after randomization did not differ (96% vs. 97%; p = 0.520). Secondary hematopoietic disorders developed in nine patients, secondary malignancies in 11, and grade 3 or more late cardiac comorbidities in three. These late complications did not differ between the two arms.

Abstract
BACKGROUND Iron overload is well documented in patients with β-thalassemia major, and patients who have undergone hematopoietic stem cell transplantation (HSCT) remain at risk as a result of pre- and immediate post-HSCT transfusions. PROCEDURE This is a prospective, randomized, 1-year clinical trial that compares the efficacy and safety of the once-daily oral iron chelator deferasirox versus phlebotomy for the treatment of iron overload in children with β-thalassemia major following HSCT. RESULTS Patients (aged 12.4 years) received deferasirox (n = 12, 10 mg/kg/day starting dose) or phlebotomy (n = 14, 6 ml/kg/2 weeks) for 1 year. In two and five patients, deferasirox dose was increased to 15 and 20 mg/kg/day, respectively. Magnetic resonance imaging (MRI)-assessed liver iron concentration (LIC) decreased with deferasirox (mean 12.5 ± 10.1 to 8.5 ± 9.3 mg Fe/g dry weight [dw]; P = 0.0005 vs. baseline) and phlebotomy (10.2 ± 6.8 to 8.3 ± 9.2 mg Fe/g dw; P = 0.05). LIC reductions were greater with deferasirox than with phlebotomy for patients with baseline serum ferritin 1,000 ng/ml or higher (-8.1 ± 1.5 vs. -3.5 ± 5.7 mg Fe/g dw; P = 0.048). Serum ferritin and non-transferrin-bound iron also decreased significantly. In two patients with severe cardiac siderosis, a clinically relevant improvement in myocardial T2* was seen, following phlebotomy and deferasirox therapy (n = 1 each). Adverse effects with deferasirox were skin rash, gastrointestinal upset, and increased liver function tests (all n = 1), while those for phlebotomy were difficulty with venous access (n = 4) and distress during procedure (n = 1). Parents of 13/14 children receiving phlebotomy wished to switch to deferasirox, with 1/14 being satisfied with phlebotomy. CONCLUSIONS Deferasirox treatment or phlebotomy reduces iron burden in pediatric patients with β- thalassemia major post-HSCT, with a manageable safety profile.

Abstract
Once-daily deferasirox dispersible tablets (DT) have a well-defined safety and efficacy profile and, compared with parenteral deferoxamine, provide greater patient adherence, satisfaction, and quality of life. However, barriers still exist to optimal adherence, including gastrointestinal tolerability and palatability, leading to development of a new film-coated tablet (FCT) formulation that can be swallowed with a light meal, without the need to disperse into a suspension prior to consumption. The randomized, open-label, phase II ECLIPSE study evaluated the safety of deferasirox DT and FCT formulations over 24 weeks in chelation-naïve or pre-treated patients aged ≥10 years, with transfusion-dependent thalassemia or IPSS-R very-low-, low-, or intermediate-risk myelodysplastic syndromes. One hundred seventy-three patients were randomized 1:1 to DT (n = 86) or FCT (n = 87). Adverse events (overall), consistent with the known deferasirox safety profile, were reported in similar proportions of patients for each formulation (DT 89.5%; FCT 89.7%), with a lower frequency of severe events observed in patients receiving FCT (19.5% vs. 25.6% DT). Laboratory parameters (serum creatinine, creatinine clearance, alanine aminotransferase, aspartate aminotransferase and urine protein/creatinine ratio) generally remained stable throughout the study. Patient-reported outcomes showed greater adherence and satisfaction, better palatability and fewer concerns with FCT than DT. Treatment compliance by pill count was higher with FCT (92.9%) than with DT (85.3%). This analysis suggests deferasirox FCT offers an improved formulation with enhanced patient satisfaction, which may improve adherence, thereby reducing frequency and severity of iron overload-related complications.

Abstract
Objectives Hypofunction of NMDA receptor is implicated in the pathophysiology, particularly cognitive impairment, of schizophrenia. Sarcosine, a glycine transporter I (GlyT-1) inhibitor, and sodium benzoate, a d-amino acid oxidase (DAAO) inhibitor, can both enhance NMDA receptor-mediated neurotransmission. We proposed simultaneously inhibiting DAAO and GlyT-1 may be more effective than inhibition of either in improving the cognitive and global functioning of schizophrenia patients. Methods This study compared add-on sarcosine (2 g/day) plus benzoate (1 g/day) vs. sarcosine (2 g/day) for the clinical symptoms, as well as the cognitive and global functioning, of chronic schizophrenia patients in a 12-week, double-blind, randomised, placebo-controlled trial. Participants were measured with the Positive and Negative Syndrome Scale and the Global Assessment of Functioning Scale every 3 weeks. Seven cognitive domains, recommended by the Measurement and Treatment Research to Improve Cognition in Schizophrenia Committee, were measured at weeks 0 and 12. Results Adjunctive sarcosine plus benzoate, but not sarcosine alone, improved the cognitive and global functioning of patients with schizophrenia, even when their clinical symptoms had not improved. Conclusions This finding suggests N-methyl-d-aspartate receptor-enhancement therapy can improve the cognitive function of patients with schizophrenia, further indicating this pro-cognitive effect can be primary without improvement in clinical symptoms.

Abstract
It has long been thought that there is a close association between hypertension and atrial fibrillation (AF). However, the efficacy of an angiotensin II receptor blocker for the prevention of organ damage in hypertensive individuals with AF is still controversial. The present study was a multicentered, prospective, randomized, open-label clinical trial investigating the differences in the effect of treatment with telmisartan/amlodipine combination tablets on blood pressure (BP) levels and BP variability between morning and bedtime administration in hypertensive patients with paroxysmal AF, using ambulatory BP monitoring (ABPM) and home BP. With this treatment, the patients' 24-hour BP, nighttime BP, preawake BP, and morning BP shown by ABPM were significantly reduced, and the antihypertensive effects were similar regardless of the timing of the drug administration. The standard deviation of day-by-day home systolic BP and the maximum home systolic BP were also significantly reduced, and these effects were similar regardless of the treatment timing. The N-terminal pro-brain natriuretic peptide level was significantly decreased only in the bedtime administration group. A larger study will demonstrate whether the bedtime administration of telmisartan/amlodipine combination tablets maximizes the risk-lowering effect against AF recurrence in paroxysmal AF hypertensive patients.

Abstract
OBJECTIVE The aim of this study was to compare the efficacy and safety of telmisartan plus amlodipine with telmisartan plus hydrochlorothiazide for the treatment of uncontrolled hypertension. METHODS Japanese hypertensive patients with uncontrolled hypertension, despite taking angiotensin II receptor blockers, were assigned randomly to either a fixed-dose combination of telmisartan/amlodipine (n=36) or telmisartan/hydrochlorothiazide (n=39). The primary endpoint was the change in office blood pressure from the baseline value at 12 weeks. RESULTS Both telmisartan/amlodipine and telmisaratan/hydrochlorothiazide reduced the office blood pressure efficiently (systole: -25.5±12.1 vs. -24.3±15.0 mmHg, P=0.705; diastole: -10.8±13.8 vs. -11.4±12.3 mmHg, P=0.832). Treatment with telmisartan/hydrochlorothiazide resulted in the quicker onset of blood pressure-lowering effects compared with telmisartan/amlodipine. The target therapeutic blood pressure was similar in both groups at the 12-week visit. Home blood pressure measurements taken in the mornings and evenings were also similar in both groups. Compared with the telmisartan/amlodipine group, serum potassium and brain natriuretic peptide levels decreased and uric acid and hemoglobin A1c levels increased significantly in the telmisartan/hydrochlorothiazide group. Both treatment groups showed a significant reduction in urine albumin. However, the estimated glomerular filtration rate decreased slightly but significantly in the telmisartan/hydrochlorothiazide group alone. Severe adverse effects were not observed in both groups. CONCLUSION Combination therapy with telmisartan/amlodipine or telmisartan/hydrochlorothiazide led to efficient blood pressure reduction among Japanese patients with previously uncontrolled hypertension with angiotensin II receptor blocker monotherapy.

Abstract
BACKGROUND/AIM: Telmisartan can attenuate two hit pathogenesis of non-alcoholic steatohepatitis (NASH). This study aimed to observe the effect of Telmisartan on non-alcoholic fatty liver disease (NAFLD) activity score (NAS) and fibrosis score in NASH patients. PATIENTS AND METHODS A total of 50 NASH patients were randomized; 35 of group 1 were treated with Telmisartan 40/80 mg once daily with life style modification (TL) and 15 of group 2 underwent only life style modification (L) for 1 year. At the end, 20 of TL group and 10 of L group were analyzed. Those who showed NAS improvement ≥ 2 or NAS improvement ≥ 1 with fibrosis improvement ≥ 1 were considered as responders. RESULTS Baseline alanine aminotransferase (ALT), aspartate aminotransferase (AST), insulin resistance index, components of metabolic syndrome, age, and sex were similar in both groups. At the end of study, NAS improvement in TL and L groups was 2.15 ± 1.66 and 1.10 ± 0.57 (P = 0.017) and fibrosis improvement was 0.65 ± 0.93 and -0.30 ± 0.48 (P = 0.001), respectively. NAS improved by ≥ 2 in 13 (65%) and 2 (20%) patients and fibrosis score improved by ≥ 1 in 8 (40%) patients and none of the patients in TL group and L group, respectively. Telmisartan and life style modification could improve steatosis, ballooning, lobular inflammation, and fibrosis. Life style modification could improve ballooning only, but fibrosis deteriorated. TL group showed improvement in NAS and fibrosis score [P value: 0.035; odds ratio (OR) =92.07, confidence interval (CI) =1.39-6106] to the level of response by regression analysis. Weight reduction and improvement of metabolic syndrome did not influence the response. There were similar minor adverse events in both groups. CONCLUSION Telmisartan improved NAS and fibrosis score in NASH with insignificant adverse events.

Abstract
UNLABELLED In women with osteoporosis treated with alendronate for >12 months and oral bisphosphonates for >3 of the last 4 years, switching to MK-5442, a calcium receptor antagonist, stimulated endogenous parathyroid hormone (PTH) secretion and increased bone turnover marker levels, but produced a decline in bone mineral density (BMD) at all sites. INTRODUCTION This study assessed the effects of switching from long-term oral bisphosphonate therapy to the calcium-sensing receptor antagonist MK-5442 on BMD and bone turnover markers (BTMs) in post-menopausal women with osteoporosis. METHODS This randomized, active and placebo-controlled, dose-ranging study enrolled 526 postmenopausal women, who had taken alendronate (ALN) for ≥12 months preceding the trial and any oral bisphosphonate for ≥3 of the preceding 4 years and had spine or hip BMD T-scores ≤-2.5 or ≤-1.5 with ≥1 prior fragility fracture. Women were randomized to continue ALN 70 mg weekly or switch to MK-5442 (5, 7.5, 10, or 15 mg daily) or placebo. RESULTS Switching from ALN to MK-5442 produced a dose-dependent parathyroid hormone (PTH) pulse of threefold to sixfold above baseline at 1 h, with PTH levels that remained twofold to threefold above baseline at 4 h and returned to baseline by 24 h. Switching to MK-5442 or placebo increased BTM levels compared to baseline within 3 months and MK-5442 10 mg increased BTM levels compared to placebo by 6 months. With all MK-5442 doses and placebo, spine and hip BMD declined from baseline, and at 12 months, BMD levels were below those who continued ALN (all groups P < 0.05 vs ALN). There was also a dose-dependent increase in the incidence of hypercalcemia with MK-5442. CONCLUSION Switching from ALN to MK-5442 resulted in a pulsatile increase in PTH and increases in BTMs, but a decline in BMD compared with continued ALN. MK-5442 is not a viable option for the treatment of osteoporosis.
