Combined therapy with carfilzomib, bendamustine, and dexamethasone was evaluated in this multicenter phase 1/2 trial conducted within the European Myeloma Network (EMN09 trial). Sixty-three patients with relapsed/refractory multiple myeloma who had received ≥2 lines of prior therapy were included. The phase 1 portion of the study determined the maximum tolerated dose of carfilzomib with bendamustine set at 70 mg/m² on days 1 and 8. After 8 cycles, responding patients received maintenance therapy with carfilzomib and dexamethasone until progression. On the basis of the phase 1 results, the recommended phase 2 dose for carfilzomib was 27 mg/m² twice weekly in weeks 1, 2, and 3. Fifty-two percent of patients achieved a partial response or better, and 32% reached a very good partial response or better. The clin. benefit rate was 93%. After a median follow-up of 21.9 mo, the median progression-free survival was 11.6 mo, and the median overall survival was 30.4 mo. The reported grade ≥3 hematol. adverse events (AEs) were lymphopenia (29%), neutropenia (25%), and thrombocytopenia (22%). The main nonhematol. grade ≥3 AEs were pneumonia, thromboembolic events (10%), cardiac AEs (8%), and hypertension (2%). In heavily pretreated patients who have relapsed/refractory multiple myeloma, combined carfilzomib, bendamustine, and dexamethasone is an effective treatment option administered in the outpatient setting. Infection prophylaxis and attention to patients with cardiovascular predisposition are required.

Suppression of vacuolar-type ATPase and induction of endoplasmic reticulum stress by proton pump inhibitors was written by Lee, Wei-Ping. And the article was included in Journal of the Chinese Medical Association in 2022.Application of 117976-90-6 The following contents are mentioned in the article:

Proton pump inhibitors (PPIs), such as esomeprazole, pantoprazole, dexlansoprazole, and rabeprazole, are one of the most commonly prescribed medications. Several studies have linked the long-term use of PPIs to a potentially increased risk of gastric cancer. Therefore, this study aimed to determine the underlying mechanism of PPI-mediated gastric cancer. Lysosomes were isolated using immunoprecipitation The inhibition of vacuolar-type ATPase (V-ATPase) by PPIs was assayed using a PiColorLock Gold Phosphate Detection System. PPI-induced lysosomal stress was analyzed using transcription factor EB (TFEB) nuclear translocation. PPI-induced endoplasmic reticulum (ER) stress was analyzed using the expression of protein kinase RNA-like endoplasmic reticulum kinase (PERK), inositol-requiring enzyme 1 (IRE1), and activating transcription factor 6 (ATF6). Finally, reactive oxygen species (ROS) removal was determined using the activity of superoxide dismutase (SOD). PPIs caused a 70% inhibition of V-ATPase activity at 20 μM, leading to lysosomal stress through TFEB nuclear translocation; ER stress by inducing the expression of PERK, IRE1, and ATF6; and enhanced SOD activity for ROS removal. The long-term use of PPIs inhibits lysosomal V-ATPase, leading to ER stress and ROS accumulation, which may result in an increased risk of gastric cancer. Because lysosomes and the ER are common organelles in cells, physicians prescribing PPIs for gastroesophageal reflux and peptic ulcer diseases should pay more attention to the general effects of these agents on the human body. This study involved multiple reactions and reactants, such as Sodium 2-(((4-(3-methoxypropoxy)-3-methylpyridin-2-yl)methyl)sulfinyl)benzo[d]imidazol-1-ide (cas: 117976-90-6Application of 117976-90-6).

Network Meta-analysis Comparing Vonoprazan and Proton Pump Inhibitors for Heartburn Symptoms in Erosive Esophagitis was written by Oshima, Tadayuki;Igarashi, Ataru;Nakano, Hiroya;Deguchi, Hisato;Fujimori, Ikuo;Fernandez, Jovelle. And the article was included in Journal of Clinical Gastroenterology in 2022.Synthetic Route of C18H20N3NaO3S The following contents are mentioned in the article:

This systematic review and network meta-anal. aimed to assess the relative efficacy of vonoprazan and proton pump inhibitors (PPIs) on early heartburn symptom resolution in patients with erosive esophagitis. Limited available data directly compare the efficacy of vonoprazan, a first-in-class potassium-competitive acid blocker, with PPIs in erosive esophagitis. We conducted a systematic literature review (in MEDLINE and CENTRAL) and subsequent network meta-anal. according to Cochrane and PRISMA guidelines. Double-blind, randomized controlled trials in adults with erosive esophagitis treated with vonoprazan or a PPI were included in the anal. Primary outcomes were heartburn symptom resolution rate on Day 1 and Day 7. The study was performed with all available data, using a random effects model within a Bayesian framework. Overall, 10 randomized controlled trials were included in the network meta-anal. For heartburn resolution rate on Day 1 (9 of 10 trials), vonoprazan 20 mg once daily (QD) was superior to placebo (median odds ratio=16.75, 95% credible interval: 2.16-207.80). Point estimates numerically favored vonoprazan 20 mg QD over other comparators. For heartburn resolution rate on Day 7 (10 of 10 trials), vonoprazan 20 mg QD was superior to placebo and other comparators except rabeprazole 20 mg QD. Point estimates numerically favored vonoprazan 20 mg QD over rabeprazole 20 mg QD. In this study, vonoprazan 20 mg QD was equally effective in heartburn resolution on Day 1, and equally or more effective on Day 7 vs. PPIs in adults with erosive esophagitis.

Effect of a rabeprazole half-dose twice daily on acid inhibition in patients with different CYP2C19 alleles was written by Murata, Masaki;Sugimoto, Mitsushige. And the article was included in European Journal of Clinical Pharmacology in 2020.Product Details of 117976-90-6 The following contents are mentioned in the article:

Abstract: Purpose: Fractional doses of proton pump inhibitors (PPIs) more often than once daily (qd) inhibit 24-h acid secretion more effectively than an increase in the standard single daily dose. Although rabeprazole 5 mg qd is covered for prevention of aspirin-induced gastric injury under the Japanese insurance system, it is unclear whether rabeprazole 5 mg twice daily (bid) would more effectively inhibit acid secretion. We compared acid inhibition between rabeprazole 10 mg qd and 5 mg bid in healthy volunteers with different alleles of CYP2C19. Methods: Twelve Helicobacter pylori-neg. healthy volunteers (CYP2C19 genotypes: extensive metabolizer (EM) (n = 6) and poor metabolizer (PM) (n = 6)) received three kinds of regimen for 7 days under a randomized crossover design: rabeprazole 5 mg qd (5 mg QD), 10 mg qd (10 mg QD), and 5 mg bid (5 mg BID). A 24-h pH monitoring was conducted before the trial and on day 7 of each regimen. Results: No significant differences in median pH values (4.0 (1.9-5.9)) and (4.4 (2.1-6.5)) or percent time of pH ≥ 4 (50.7% (11.9-86.8%) and 56.8% (19.3-83.9%)) were seen between the 10 mg QD and 5 mg BID regimens. Median pHs and percent time of pH ≥ 4 in CYP2C19 PMs were significantly higher than those in EMs. With 5 mg BID, there was no significant difference in percent-time with pH ≥ 4 between daytime and nighttime, but the 10 mg QD showed a significant difference. Conclusion: Rabeprazole 5 mg bid provided no therapeutic advantage for acid inhibition compared with rabeprazole 10 mg qd, regardless of CYP2C19 genotype status. This study involved multiple reactions and reactants, such as Sodium 2-(((4-(3-methoxypropoxy)-3-methylpyridin-2-yl)methyl)sulfinyl)benzo[d]imidazol-1-ide (cas: 117976-90-6Product Details of 117976-90-6).

Impact of proton pump inhibitors on cytochrome P450 activity assessed by ¹³C-aminopyrine breath test in patients with cirrhosis was written by Rocco, Alba;Compare, Debora;Sgamato, Costantino;Coccoli, Pietro;Chiodini, Paolo;Nardone, Gerardo. And the article was included in Alimentary Pharmacology and Therapeutics in 2021.Application In Synthesis of Sodium 2-(((4-(3-methoxypropoxy)-3-methylpyridin-2-yl)methyl)sulfinyl)benzo[d]imidazol-1-ide The following contents are mentioned in the article:

Summary : Background : Chronic use of proton pump inhibitors (PPIs) in patients with impaired liver function may worsen cytochrome P 450 (CYP450) activity, predisposing them to clin. relevant drug-drug interactions. The 13C-aminopyrine breath test (13C-ABT) is a non-invasive tool to study CYP450-dependent liver function. Aims : To assess 13C-ABT modifications with different PPIs in patients with cirrhosis. Methods : Sixty consecutive patients with HCV-related cirrhosis and indication to start PPI therapy were randomised to receive omeprazole 20 mg/day, esomeprazole 20 mg/day, lansoprazole 15 mg/day, pantoprazole 40 mg/day or rabeprazole 20 mg/day. 13C-ABT was performed at baseline and on the 15th day of PPI therapy. Results : At baseline, mean values of max 13C% dose/h and 13C% cum dose at 120 min did not differ significantly among groups. On the 15th day of therapy, max 13C% dose/h and 13C% cum dose at 120 min did not significantly differ with respect to baseline for pantoprazole (P = 0.184 and P = 0.309, resp.) or rabeprazole (P = 0.536 and P = 0.286, resp.), but were significantly decreased on omeprazole (P = 0.013 and P = 0.015, resp.), esomeprazole (P = 0.009 and P = 0.001, resp.), and lansoprazole (P = 0.033 and P = 0.035, resp.). Conclusions : In patients with cirrhosis, omeprazole, esomeprazole and lansoprazole inhibit microsomal activity while pantoprazole and rabeprazole do not have a significant impact. Should our data be confirmed in larger cohort studies, pantoprazole and rabeprazole could be safely recommended for patients with cirrhosis.

Efficacy and safety assessment of prolonged maintenance with subcutaneous rituximab in patients with relapsed or refractory indolent non-Hodgkin lymphoma: results of the phase III MabCute study was written by Rule, Simon;Barreto, Wolney Gois;Briones, Javier;Carella, Angelo M.;Casasnovas, Olivier;Pocock, Chris;Wendtner, Clemens-Martin;Zaja, Francesco;Robson, Susan;MacGregor, Lachlan;Tschopp, Roger R.;Nick, Sonja;Dreyling, Martin.

Rituximab plus chemotherapy induction followed by rituximab maintenance for up to 2 years confers a long-term benefit in terms of progression-free survival in patients with indolent non-Hodgkin lymphoma. It is not known whether further prolonged maintenance with rituximab provides addnl. benefit. The phase III MabCute study enrolled 692 patients with relapsed or refractory indolent non-Hodgkin lymphoma. Patients who responded to induction with rituximab plus chemotherapy and were still responding after up to 2 years’ initial maintenance with s.c. rituximab were randomized to extended maintenance with s.c. rituximab (n=138) or observation only (n=138). The primary endpoint of investigator-assessed progression-free survival in the randomized population was un-addressed by the end of study because of an insufficient number of events (129 events were needed for 80% power at 5% significance if approx. 330 patients were randomized). In total, there were 46 progression-free survival events, 19 and 27 in the rituximab and observation arms, resp. (P=0.410 by stratified log-rank test; hazard ratio 0.76 [95% confidence interval: 0.37-1.53]). The median progression-free survival was not reached in either randomized arm. There were no new safety signals; however, adverse events were seen slightly more frequently with rituximab than with observation during extended maintenance. Maintenance for up to 2 years with rituximab after response to initial induction therefore remains the standard of care in patients with relapsed or refractory indolent non-Hodgkin lymphoma.

Best treatment option for patients with refractory aggressive B-cell lymphoma in the CAR-T cell era: real-world evidence from GELTAMO/GETH Spanish groups was written by Bastos-Oreiro, Mariana;Gutierrez, Antonio;Reguera, Juan Luis;Iacoboni, Gloria;Lopez-Corral, Lucia;Terol, Mara Jose;Ortiz-Maldonado, Valentin;Sanz, Jaime;Guerra-Dominguez, Luisa;Bailen, Rebeca;Mussetti, Alberto;Abrisqueta, Pau;Hernani, Rafael;Luzardo, Hugo;Sancho, Juan-Manuel;Delgado-Serrano, Javier;Salar, Antonio;Grande, Carlos;Bento, Leyre;de Villambrosa, Sonia Gonzalez;Garcia-Belmonte, Daniel;Sureda, Anna;Perez-Martinez, Antonio;Barba, Pere;Kwon, Mi;Garcia-Sancho, Alejandro Martin. And the article was included in Frontiers in Immunology in 2022.Formula: C16H21Cl2N3O2 The following contents are mentioned in the article:

Real-world evidence comparing the efficacy of chimeric antigen receptor (CAR) T-cell therapy against that of the previous standard of care (SOC) for refractory large B-cell lymphoma (LBCL) is scarce. We retrospectively collected data from patients with LBCL according to SCHOLAR-1 criteria treated with com. CAR T-cell therapy in Spain (204 patients included and 192 treated, 101 with axicabtagene ciloleucel [axi-cel], and 91 with tisagenlecleucel [tisa-cel]) and compared the results with a historical refractory population of patients (n = 81) obtained from the GELTAMO-IPI study. We observed superior efficacy for CAR-T therapy (for both axi-cel and tisa-cel) over pSOC, with longer progression-free survival (PFS) (median of 5.6 vs. 4-6 mo, p ≤ 0.001) and overall survival (OS) (median of 15 vs. 8 mo, p < 0.001), independently of other prognostic factors (HR: 0.59 (95% CI: 0.44-0.80); p < 0.001 for PFS, and 0.45 (95% CI: 0.31-0.64) for OS). Within the CAR-T cohort, axi-cel showed longer PFS (median of 7.3 vs. 2.8 mo, resp., p = 0.027) and OS (58% vs. 42% at 12 mo, resp., p = 0.048) than tisa-cel. These differences were maintained in the multivariable anal. On the other hand, axi-cel was independently associated with a higher risk of severe cytokine release syndrome and neurotoxicity. Our results suggest that the efficacy of CAR-T cell therapy is superior to pSOC in the real-world setting. Furthermore, axi-cel could be superior in efficacy to tisa-cel, although more toxic, in this group of refractory patients according to SCHOLAR-1 criteria.

Identifying the best regimen for primary eradication of Helicobacter pylori: analysis of 240 cases was written by Chen, Yao;Liu, Qingyi;Hu, Fulian;Ma, Jizheng. And the article was included in MicrobiologyOpen in 2020.Formula: C18H20N3NaO3S The following contents are mentioned in the article:

The treatment regimen for the eradication of Helicobacter pylori may be best when therapy is susceptibility guided. However, it is unrealistic to use a strategy based on susceptibility testing to prioritize therapy for every patient in China. Empirical therapy of H. pylori is still widely used. The study was designed to discuss the best first-line treatment regimen depending on empirical therapy. The focal point of the study was the optimal length of the therapy. Also, the selection of antibiotics was discussed in the article. This was a prospective, randomized, non-inferiority trial. H. pylori-infected patients who have no previous eradication therapy were randomly assigned to the following: 20 mg of rabeprazole, 1000 mg of amoxicillin, 500 mg of clarithromycin, and 220 mg of bismuth potassium citrate (BACPPI), administered twice a day for 10 or 14 days. The efficacy, side effects, and remission rate of clin. symptoms were determined A total of 240 subjects were included in the study. The eradication rate with 14 and 10 days was essentially identical in both intention-to-treat (90.83% [95% CI, 86%-96%] vs. 87.50% [95% CI, 82%-93%]) and per-protocol (94.78% [95% CI, 91%-99%] vs. 92.11% [95% CI, 87%-97%]) analyses. Loss of appetite and belching symptoms were significantly better in the BACPPI-10 group than those in the control group after treatment. Side effects were generally mild and similar between groups. Our results showed that a 10-day amoxicillin-clarithromycin-containing bismuth quadruple therapy may be recommended for the primary empirical treatment of H. pylori infection in Beijing, China.

A novel Liquid Chromatog.-tandem mass spectrometry (LC-MS/MS) method is presented for the quant. determination of two potential genotoxic impurities (PGIs) in rabeprazole active pharmaceutical ingredient (API). In order to overcome the anal. challenges in the trace anal. of PGIs, a development procedure supported by Quality-by-Design (QbD) principles was evaluated. The efficient separation between rabeprazole and the two PGIs in the shortest anal. time was set as the defined anal. target profile (ATP) and to this purpose utilization of a switching valve allowed the flow to be sent to waste when rabeprazole was eluted. The selected critical quality attributes (CQAs) were the separation criterion s between the critical peak pair and the capacity factor k of the last eluted compound The effect of the following critical process parameters (CPPs) on the CQAs was studied: %ACN content, the pH and the concentration of the buffer salt in the mobile phase, as well as the stationary phase of the anal. column. D-Optimal design was implemented to set the plan of experiments with UV detector. In order to define the design space, Monte Carlo simulations with 5000 iterations were performed. Acceptance criteria were met for C₈ column (50 × 4 mm, 5 μm), and the region having probability π ≥ 95% to achieve satisfactory values of all defined CQAs was computed. The working point was selected with the mobile phase consisting of ACN, ammonium formate 11 mM at a ratio 31/69 volume/volume with pH = 6,8 for the water phase.

Diffuse large B-cell lymphoma (DLBCL) is nowadays a curable disease with the frontline treatment R-CHOP, but 30-40% of patients are still unresponsive or relapse thereafter. In the recent era several upcoming new options are improving the therapeutic landscape for relapsed/refractory (R/R) DLBCL setting, first of all anti-CD19 chimeric antigen receptor T-cells (CAR-T) that already represent a standard of care as third-line therapy and are rapidly moving as second-line treatment for those who are refractory or early relapse after R-CHOP. Among these new therapies, the combinations polatuzumab plus rituximab and bendamustine, tafasitamab plus lenalidomide for transplant ineligible patients, and CD3xCD20 bispecific antibodies are the most relevant, but several other agents and strategies are on the way. On the other hand, in the last 20 years, several efforts have been spent in the attempt to ameliorate the outcome over R-CHOP for the frontline treatment of DLBCL shortening the interval between the cycles or intensifying treatment or adding novel drugs to R-CHOP without success, so far. Recent studies combining the anti-CD79b antibody-drug conjugate polatuzumab vedotin plus R-CHP and the anti-BCL2 agent venetoclax plus R-CHOP showed promising results. Preliminary data of new upcoming strategies characterized by a tailored therapy based on different mol. subtypes of DLBCL are encouraging, showing a benefit over the standard R-CHOP. In this manuscript, the literature data on the landscape of new therapies available and upcoming for both frontline and R/R settings of DLBCL will be critically reviewed.
