- Abstract
Importance There is a major need for effective, well-tolerated treatments for idiopathic pulmonary fibrosis (IPF). Objective To assess the efficacy and safety of the autotaxin inhibitor ziritaxestat in patients with IPF. Design, Setting, and Participants The 2 identically designed, phase 3, randomized clinical trials, ISABELA 1 and ISABELA 2, were conducted in Africa, Asia-Pacific region, Europe, Latin America, the Middle East, and North America (26 countries). A total of 1306 patients with IPF were randomized (525 patients at 106 sites in ISABELA 1 and 781 patients at 121 sites in ISABELA 2). Enrollment began in November 2018 in both trials and follow-up was completed early due to study termination on April 12, 2021, for ISABELA 1 and on March 30, 2021, for ISABELA 2. Interventions Patients were randomized 1:1:1 to receive 600 mg of oral ziritaxestat, 200 mg of ziritaxestat, or placebo once daily in addition to local standard of care (pirfenidone, nintedanib, or neither) for at least 52 weeks. Main Outcomes and Measures The primary outcome was the annual rate of decline for forced vital capacity (FVC) at week 52. The key secondary outcomes were disease progression, time to first respiratory-related hospitalization, and change from baseline in St George’s Respiratory Questionnaire total score (range, 0 to 100; higher scores indicate poorer health-related quality of life). Results At the time of study termination, 525 patients were randomized in ISABELA 1 and 781 patients in ISABELA 2 (mean age: 70.0 [SD, 7.2] years in ISABELA 1 and 69.8 [SD, 7.1] years in ISABELA 2; male: 82.4% and 81.2%, respectively). The trials were terminated early after an independent data and safety monitoring committee concluded that the benefit to risk profile of ziritaxestat no longer supported their continuation. Ziritaxestat did not improve the annual rate of FVC decline vs placebo in either study. In ISABELA 1, the least-squares mean annual rate of FVC decline was –124.6 mL (95% CI, −178.0 to −71.2 mL) with 600 mg of ziritaxestat vs –147.3 mL (95% CI, −199.8 to −94.7 mL) with placebo (between-group difference, 22.7 mL [95% CI, −52.3 to 97.6 mL]), and –173.9 mL (95% CI, −225.7 to −122.2 mL) with 200 mg of ziritaxestat (between-group difference vs placebo, −26.7 mL [95% CI, −100.5 to 47.1 mL]). In ISABELA 2, the least-squares mean annual rate of FVC decline was –173.8 mL (95% CI, −209.2 to −138.4 mL) with 600 mg of ziritaxestat vs –176.6 mL (95% CI, −211.4 to −141.8 mL) with placebo (between-group difference, 2.8 mL [95% CI, −46.9 to 52.4 mL]) and –174.9 mL (95% CI, −209.5 to −140.2 mL) with 200 mg of ziritaxestat (between-group difference vs placebo, 1.7 mL [95% CI, −47.4 to 50.8 mL]). There was no benefit with ziritaxestat vs placebo for the key secondary outcomes. In ISABELA 1, all-cause mortality was 8.0% with 600 mg of ziritaxestat, 4.6% with 200 mg of ziritaxestat, and 6.3% with placebo; in ISABELA 2, it was 9.3% with 600 mg of ziritaxestat, 8.5% with 200 mg of ziritaxestat, and 4.7% with placebo. Conclusions and Relevance Ziritaxestat did not improve clinical outcomes compared with placebo in patients with IPF receiving standard of care treatment with pirfenidone or nintedanib or in those not receiving standard of care treatment.

- Abstract
Background: The INBUILD trial investigated the efficacy and safety of nintedanib versus placebo in patients with progressive fibrosing interstitial lung diseases (ILDs) other than idiopathic pulmonary fibrosis (IPF). We aimed to establish the effects of nintedanib in subgroups based on ILD diagnosis. Methods: The INBUILD trial was a randomised, double-blind, placebo-controlled, parallel group trial done at 153 sites in 15 countries. Participants had an investigator-diagnosed fibrosing ILD other than IPF, with chest imaging features of fibrosis of more than 10% extent on high resolution CT (HRCT), forced vital capacity (FVC) of 45% or more predicted, and diffusing capacity of the lung for carbon monoxide (DLco) of at least 30% and less than 80% predicted. Participants fulfilled protocol-defined criteria for ILD progression in the 24 months before screening, despite management considered appropriate in clinical practice for the individual ILD. Participants were randomly assigned 1:1 by means of a pseudo-random number generator to receive nintedanib 150 mg twice daily or placebo for at least 52 weeks. Participants, investigators, and other personnel involved in the trial and analysis were masked to treatment assignment until after database lock. In this subgroup analysis, we assessed the rate of decline in FVC (mL/year) over 52 weeks in patients who received at least one dose of nintedanib or placebo in five prespecified subgroups based on the ILD diagnoses documented by the investigators: hypersensitivity pneumonitis, autoimmune ILDs, idiopathic non-specific interstitial pneumonia, unclassifiable idiopathic interstitial pneumonia, and other ILDs. The trial has been completed and is registered with ClinicalTrials.gov, number NCT02999178. Findings: Participants were recruited between Feb 23, 2017, and April 27, 2018. Of 663 participants who received at least one dose of nintedanib or placebo, 173 (26%) had chronic hypersensitivity pneumonitis, 170 (26%) an autoimmune ILD, 125 (19%) idiopathic non-specific interstitial pneumonia, 114 (17%) unclassifiable idiopathic interstitial pneumonia, and 81 (12%) other ILDs. The effect of nintedanib versus placebo on reducing the rate of FVC decline (mL/year) was consistent across the five subgroups by ILD diagnosis in the overall population (hypersensitivity pneumonitis 73·1 [95% CI −8·6 to 154·8]; autoimmune ILDs 104·0 [21·1 to 186·9]; idiopathic non-specific interstitial pneumonia 141·6 [46·0 to 237·2]; unclassifiable idiopathic interstitial pneumonia 68·3 [−31·4 to 168·1]; and other ILDs 197·1 [77·6 to 316·7]; p=0·41 for treatment by subgroup by time interaction). Adverse events reported in the subgroups were consistent with those reported in the overall population. Interpretation: The INBUILD trial was not designed or powered to provide evidence for a benefit of nintedanib in specific diagnostic subgroups. However, its results suggest that nintedanib reduces the rate of ILD progression, as measured by FVC decline, in patients who have a chronic fibrosing ILD and progressive phenotype, irrespective of the underlying ILD diagnosis.

Chronic lung allograft dysfunction (CLAD) is the leading long-term cause of poor outcomes after transplant and manifests by fibrotic remodeling of small airways and/or pleuroparenchymal fibroelastosis. This study evaluated the effect of pirfenidone on spirometric and radiographic progression in patients with CLAD. We performed a single-center, 6-month, randomized, placebo-controlled trial of pirfenidone on patients with CLAD. Treatment allocation was stratified by CLAD phenotype. The primary spirometric outcome measures were change FEV1 and FVC relative to post-transplant baseline values, and the primary radiographic outcome was small airways disease, quantified as percentage of lung volume via parametric response mapping analysis of CT scans (PRMfSAD). Linear mixed models were used to evaluate treatment effect of the longitudinal outcome measures. We enrolled 24 patients, 13 of whom received pirfenidone (the study was terminated prior to reaching target enrollment of 60 patients due to the COVID pandemic). The pirfenidone and placebo groups were similar with regards to age, pre-transplant diagnosis, lung function, and CLAD phenotypes. There was no significant difference between the pirfenidone vs. placebo groups with regards to expected change in FEV1 (-3.1 vs. -3.7, p =0.90, Figure Panel A), FVC (-2.5 vs. -4.6, p =0.63, Figure Panel B), or PRMfSAD (+3.7 vs. -0.6, p =0.28). Subgroup analysis found that pirfenidone attenuated the spirometric decline among female patients, but there was no difference in treatment effect with regards to age, pre-transplant diagnosis, or CLAD phenotype. Tolerance of study drug and adverse events did not differ between groups, although the rate of grade 2 or higher adverse events was higher in the placebo vs. pirfenidone group (13 vs. 7, p =0.001). Pirfenidone did not attenuate spirometric or radiographic decline in a single-center randomized trial of CLAD patients, but had an acceptable tolerance and side effect profile. [ABSTRACT FROM AUTHOR]

- Abstract
Five methoxytetrahydronaphthalene derivatives, new agonist and antagonist ligands for melatonin receptors, were resolved into their diastereomers by analytical HPLC methods using derivatized amylose, chiral stationary phases. Separation was by using normal phase methodology with a mobile phase of n-hexane-alcohol (ethanol or 2-propanol) and a silica-based amylose tris-( S)-1-phenylethylcarbamate (Chiralpak AS), or tris-3,5-dimethylphenylcarbamate (Chiralpak AD). The effects of structural variation in the solutes were noted. Baseline separation was easily obtained in many cases. [ABSTRACT FROM AUTHOR]

Several clinical trials have shown that the inhaled β 2 -agonists with long-acting properties, formoterol and salmeterol, may be effective in acute exacerbations of chronic obstructive pulmonary disease (COPD). However, there is a great deal of controversy regarding the timing and optimal dose of inhaled β 2 -agonists in this pathologic condition. In this double-blind, randomised, crossover study, we have compared the bronchodilating effect and the safety of inhaled formoterol administered via Turbuhaler using either a cumulative dose regimen or the equivalent single dose in 16 patients with acute exacerbations of COPD. On the two consecutive days, the patients received, in a randomised order, each of the following active dose regimens: (A): 9 + 9 + 18 μg of formoterol via Turbuhaler (36 μg cumulative delivered dose), or (B): 36 + 0 + 0 μg of formoterol via Turbuhaler. The three doses on each treatment day were administered at 30-mm intervals, with measurements being made 5 and 30 min after each dose. Contemporaneously, we also measured oxygen saturation by pulse oximetry ( S pO 2 ) and pulse rate. Both the high dose and the cumulative one induced a significant bronchodilation expressed as change in FEV 1 . The difference between the two regimens was significant ( P =0.0332) only 60 min after the first inhalation. The trend of FVC and IC was similar to that of FEV 1 . All treatment regimens were well tolerated and no adverse events were reported. Neither the administration of the high dose nor that of the cumulative one modified heart rate in a significant manner. Also they did not influence S pO 2 . This study indicates that a single high dose of formoterol is as effective as the same dose administered in a cumulative manner in patients with acute exacerbation of COPD.

- Abstract
Objectives: To establish a framework by which experts define disease subsets in systemic sclerosis associated interstitial lung disease (SSc-ILD)., Methods: A conceptual framework for subclinical, clinical and progressive ILD was provided to 83 experts, asking them to use the framework and classify actual SSc-ILD patients. Each patient profile was designed to be classified by at least four experts in terms of severity and risk of progression at baseline; progression was based on 1-year follow-up data. A consensus was reached if ≥75% of experts agreed. Experts provided information on which items were important in determining classification., Results: Forty-four experts (53%) completed the survey. Consensus was achieved on the dimensions of severity (75%, 60 of 80 profiles), risk of progression (71%, 57 of 80 profiles) and progressive ILD (60%, 24 of 40 profiles). For profiles achieving consensus, most were classified as clinical ILD (92%), low risk (54%) and stable (71%). Severity and disease progression overlapped in terms of framework items that were most influential in classifying patients (forced vital capacity, extent of lung involvement on high resolution chest CT [HRCT]); risk of progression was influenced primarily by disease duration., Conclusions: Using our proposed conceptual framework, international experts were able to achieve a consensus on classifying SSc-ILD patients along the dimensions of disease severity, risk of progression and progression over time. Experts rely on similar items when classifying disease severity and progression: a combination of spirometry and gas exchange and quantitative HRCT., (© The Author(s) 2022.

- Abstract
The growing use of guidelines to manage asthmatic patients prompted us to evaluate their impact on clinical practice. This study was performed in two similar groups of asthmatic patients. A retrospective and prospective review of medical records in an asthmatic population was performed. The patients were followed up for a mean period of 2 years before (group 1 [G1]) and after the publication of the Guideline for Asthma Treatment (group 2 [G2]). After evaluation of objective/clinical measurements we noticed a significant difference between both groups. There were 23 and 40 patients who did not complain of any respiratory symptoms in G1 and G2, respectively. The total number of visits to the emergency department decreased by more than 75%, from 26 (G1) to six (G2). The forced expiratory volume in 1 sec improved by a mean of 4% in G1 and 9% in G2. After application of the guidelines there was a redistribution of the degree of disease severity. In G2, there was a 12% increase in the use of long-acting beta2-stimulating sprays; 40% of the patients were using a combination of a long-acting beta2-stimulating drug and an inhaled steroid. In our experience, the use of the Global Initiative for Asthma (GINA) guidelines leads to better management of asthma patients with different degrees of severity. These findings suggest the need to perform a similar analysis in a broader setting such as a national multicenter survey in order to collect information on the challenges of putting these theoretical difficulties into practice and to compare their implementation in distinct centers.

- Abstract
Tetrahydronaphthalenic analogues of melatonin have been synthesized and evaluated as melatonin receptor ligands. Introduction of a phenyl substituent in the 3-position of the tetraline ring allows to obtain MT(2) selective ligands. Activity and MT(2) selectivity can be modulated with suitable modifications of the N-acyl substituent. The (+)-(RR)-cis enantiomer of the N-[2-(7-methoxy-3-phenyl-1,2,3,4-tetrahydro-naphthalen-1-yl)ethyl]cyclobutyl carboxamide (14) is one of the most MT(2) selective ligands described until now and behaves as an antagonist.

- Abstract
We reported a method of determination of enantiomeric purity of the new potential antiviral agents by direct analytical HPLC. Those agents are nucleoside analogs, having one chiral center. They are synthesized as a single enantiomer (R or S) by an asymmetric pathway. The chiral stationary phases chosen are silica-based cellulose tris-3,5-dimethylphenylcarbamate (Chiralcel OD-H), or tris-methylbenzoate (Chiralcel OJ). Resolution was achieved using normal-phase chromatography with a mobile phase consisting of n-hexane-alcohol (ethanol or 2-propanol) in various percentages. Furthermore the effects of structural features on retention, selectivity and resolution, as well as on the elution order were thoroughly studied. Differences in the lipophilicity of the compounds were also examined.

- Abstract
This paper describes the separation of the four sets of stereoisomers of nucleoside analogs, new potential antiviral agents by direct analytical HPLC methods using derivatized cellulose and amylose chiral stationary phases. The resolution was made using normal-phase methodology with a mobile phase consisting of n-hexane-alcohol (ethanol or 2-propanol) in various percentages, and a silica-based cellulose tris-3,5-dimethylphenylcarbamate (Chiralcel OD-H), or tris-methylbenzoate (Chiralcel OJ) and a silica-based amylose tris-3,5-dimethylphenylcarbamate (Chiralpak AD) or tris-(S)-1-phenylethylcarbamate (Chiralpak AS). The effects of structural features on the extent of discrimination between the stereoisomers were examined through the retention, the selectivity and the resolution factors as well as the elution order. Baseline separation (Rs>1.5) was easily obtained in many cases. The resolution results were complementary between the different columns.

- Abstract
In order to obtain milligram amounts of the enantiomers of tetrahydronaphthalenic derivative 5 to be tested for binding to the melatonin sites, preparative HPLC employed a mobile phase consisting of n-hexane-alcohol and a silica-based cellulose tris-methylbenzoate (Chiralcel OJ) using isocratic conditions and multiple repetitive injections. The preparative separation was optimized by adjusting the sample size from a scale-up of the analytical method. The enantiomeric elution order was reversed by the change from the carbamate type phase (Chiralcel OD-H) to the benzoate type phase (Chiralcel OJ) in analytical mode. The optical rotation and the circular dichroism spectra of the single enantiomers were determined after separation. The absolute stereochemistry of the two enantiomers of (+/-)-N-[2-(7-fluoro-1,2,3,4-tetrahydronaphthalen-1-yl)ethyl]acetamide 5 was established by X-ray crystallographic analysis. The purity obtained was sufficient for a first screen of their biochemical properties: the (-)-(S) enantiomer shows more affinity for melatonin receptors MT1, MT2 and is responsible of the selectivity towards MT2.
