The 7-day standard triple therapy (STT) gives unacceptablly low eradication rates of Helicobacter pylori (H. pylori). We aimed to examine whether extending STT from 7 days to 14 days or adding a bismuth compound to a 7-day STT would result in better eradication rates. H. pylori-pos. patients were assigned to Group A (7-day STT; rabeprazole 20 mg twice daily, amoxicillin 1 g twice daily, and clarithromycin 500 mg twice daily, for 7 days), Group B (7-day STT with bismuth; rabeprazole 20 mg twice daily, amoxicillin 1 g twice daily, clarithromycin 500 mg twice daily and bismuth subcitrate 240 mg twice daily, for 7 days) and Group C (14-day STT; rabeprazole 20 mg twice daily, amoxicillin 1 g twice daily, and clarithromycin 500 mg twice daily for 14 days). Eradication was tested using ¹³C-UBT at least 4 wk after the completion of therapy. A total of 364 patients were recruited. In the intention-to-treat anal., eradication rates were 79.3% (96/121; 95% confidence interval [CI] 71.3-85.6%) for 7-day STT, 81.7% (98/120; 95% CI 73.8-87.6%) for 7-day STT with bismuth, and 88.6% (109/123; 95% CI 81.8-93.1%) for 14-day STT, resp. Statistical significance was achieved between the 7-day and the 14-day STT treatment (P = 0.048). Adding bismuth to the 7-day STT did not result in an increase in the eradication rate. Extending the STT to 14 days, however, achieved a significantly higher eradication rate. Nevertheless, this did not achieve the targeted 90% eradication rate on intention-to-treat anal. 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: 117976-90-6Category: imidazoles-derivatives).

Autoimmune hemolytic anemia: causes and consequences was written by Fattizzo, B.;Barcellini, W.. And the article was included in Expert Review of Clinical Immunology in 2022.Recommanded Product: 4-(5-(Bis(2-chloroethyl)amino)-1-methyl-1H-benzo[d]imidazol-2-yl)butanoic acid The following contents are mentioned in the article:

A review. Autoimmune hemolytic anemia (AIHA) is classified according to the direct antiglobulin test (DAT) and thermal characteristics of the autoantibody into warm and cold forms, and in primary vs. secondary depending on the presence of associated conditions. AIHA displays a multifactorial pathogenesis, including genetic (association with congenital conditions and certain mutations), environmental (drugs, infections, including SARS-CoV-2, pollution, etc.), and miscellaneous factors (solid/hematol. neoplasms, systemic autoimmune diseases, etc.) contributing to tolerance breakdown. Several mechanisms, such as autoantibody production, complement activation, monocyte/macrophage phagocytosis, and bone marrow compensation are implicated in extra-/intravascular hemolysis. Treatment should be differentiated and sequenced according to AIHA type (i.e. steroids followed by rituximab for warm, rituximab alone or in association with bendamustine or fludarabine for cold forms). Several new drugs targeting B-cells/plasma cells, complement, and phagocytosis are in clin. trials. Finally, thrombosis and infections may complicate disease course burdening quality of life and increasing mortality. Beyond warm and cold AIHA, a gray-zone still exists including mixed and DAT neg. forms representing an unmet need. AIHA management is rapidly changing through an increasing knowledge of the pathogenic mechanisms, the refinement of diagnostic tools, and the development of novel targeted and combination therapies. This study involved multiple reactions and reactants, such as 4-(5-(Bis(2-chloroethyl)amino)-1-methyl-1H-benzo[d]imidazol-2-yl)butanoic acid (cas: 16506-27-7Recommanded Product: 4-(5-(Bis(2-chloroethyl)amino)-1-methyl-1H-benzo[d]imidazol-2-yl)butanoic acid).

Characteristics of cutaneous adverse drug reactions caused by triple-combination drug therapy used for Helicobacter pylori eradication was written by Kikuchi, Sota;Nobeyama, Yoshimasa;Saeki, Hidehisa;Asahina, Akihiko. And the article was included in Journal of Dermatology in 2020.Name: Sodium 2-(((4-(3-methoxypropoxy)-3-methylpyridin-2-yl)methyl)sulfinyl)benzo[d]imidazol-1-ide The following contents are mentioned in the article:

Cutaneous adverse drug reactions (cADR) should be appropriately managed in drug administration. LANSAP, Rabecure and VONOSAP are currently used for Helicobacter pylori eradication therapy. Here, we examined the characteristics of cADR caused by these drugs using data from the Pharmaceuticals and Medical Devices Agency (PMDA). Periods subject to analyses were set according to the year of release of these drugs: (i) from 2008 to 2017 for LANSAP; (ii) from 2014 to 2017 for Rabecure; and (iii) 2017 for VONOSAP. Among all cADR reported to the PMDA, those attributed to LANSAP, Rabecure and VONOSAP accounted for 2.3%, 1.0% and 3.6% of cases, resp. cADR occurred in patients aged in their 20s or older, with the oldest patients aged in their 60s. Numbers of male and female patients were 28 and 70 for LANSAP, eight and 14 for Rabecure and three and 16 for VONOSAP, resp. Statistical analyses revealed significant sex differences for LANSAP (P = 0.022) and VONOSAP (P = 0.012), but not for Rabecure (P = 0.729). LANSAP, Rabecure or VONOSAP caused erythema multiforme in the largest population of patients and Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) in three patients. Ratios of SJS/TEN were 0.0-5.3% for LANSAP, Rabecure or VONOSAP, but 11.5-44.8% for the corresponding single constituent drugs other than vonoprazan. In conclusion, female sex appears to represent a risk factor for cADR attributed to H. pylori eradication therapy using LANSAP or VONOSAP, although H. pylori eradication therapy without these drugs rarely causes severe cADR.

Polatuzumab (Pola)-based regimens and chimeric antigen receptor T (CAR T) cells provide superior outcome compared to conventional chemoimmunotherapy in patients with relapsed/refractory diffuse large B cell lymphoma (R/R DLBCL). Choosing between these strategies remains controversial. The efficacy of CAR T vs. Pola-rituximab(R) /Pola-bendamustine(B)-R in R/R DLBCL patients after failing ≥2 lines of treatment was compared in a retrospective, ‘real-world’ study. Propensity score matching, for age, lymphoma category (de-novo/transformed), number of prior lines, Eastern Cooperative Oncol. Group performance status and lactate dehydrogenase level, was applied to control for differences in patients’ characteristics. Response rate, progression-free survival (PFS) and overall survival (OS) were analyzed. A total of 82 patients, treated with CAR T (n = 41) or Pola-based regimens (n = 41), were included. No treatment-related deaths occurred with CAR T vs. 3 (7.3%) with Pola. The overall and complete response rates were 83% and 58% with CAR T vs. 66% and 44% with Pola-based-regimens (p = 0.077 and p = 0.18, resp.). At a median follow-up of 9 mo (range 1-19.2) and 16 mo (range 0.7-25.3) for the CAR T and Pola arm resp., the median PFS has not been reached for CAR T vs. 5.6 mo for Pola (95% CI 3.6-7.6, p = 0.014). Median OS has not been reached for CAR T vs. 10.8 mo (95% CI 2.2-19.4) for Pola (p = 0.026). To conclude, in a real-world setting, treatment with CAR T achieved superior PFS and OS compared to Pola-based regimens in patients with R/R DLBCL.

Coadministration with bendamustine restores the antitumor activity of obinutuzumab in obinutuzumab-resistant tumors was written by Yamashita-Kashima, Yoriko;Yorozu, Keigo;Fujimura, Takaaki;Kawasaki, Natsumi;Kurasawa, Mitsue;Yoshiura, Shigeki;Harada, Naoki;Kondoh, Osamu;Yoshimura, Yasushi. And the article was included in International Journal of Hematology in 2022.COA of Formula: C16H21Cl2N3O2 The following contents are mentioned in the article:

The glycoengineered, humanized anti-CD20 antibody obinutuzumab is indicated for previously untreated or relapsed/refractory CD20-pos. follicular lymphoma (FL). However, the effectiveness of obinutuzumab retreatment in relapsed/refractory FL after prior obinutuzumab-containing therapy is unclear. To address this issue, we investigated the antitumor activity of obinutuzumab plus bendamustine in obinutuzumab-resistant tumors established from a human non-Hodgkin lymphoma xenograft model. Obinutuzumab-resistant tumors (SU-DHL-4-OR-18-8) were established from an SU-DHL-4 xenograft model by repeated administration of obinutuzumab. Antitumor activity was evaluated based on tumor volume after treatment with obinutuzumab on Day 1, 8, and 15 and/or bendamustine on Day 1 and 2. Intratumoral natural killer (NK) cells/macrophages were evaluated by immunohistochem. and flow cytometry. In SU-DHL-4-OR-18-8 xenografted tumors, intratumoral NK cells/macrophages after obinutuzumab treatment were significantly decreased compared with parent tumors on Day 4. The endoplasmic reticulum stress sensor phospho-IRE1 was also decreased. In SU-DHL-4-OR-18-8 tumors, bendamustine treatment increased phospho-IRE1 on Day 4 and intratumor NK cells/macrophages on Day 10. Obinutuzumab combined with bendamustine significantly increased antitumor activity compared with each single agent on Day 29, with an increase in chemoattractant CCL6 expression on Day 10. Coadministration of bendamustine in obinutuzumab retreatment may be effective against obinutuzumab-resistant tumors.

To develop novel dual release prototype capsule formulations of rabeprazole and evaluation of pharmacokinetic properties relative to the reference product (Aciphex) in Beagle dogs. The dual release prototype formulations for rabeprazole were developed by preparing optimized mini-tablets core which was subsequently coated with barrier/enteric coating using standard excipients. Both novel prototype formulations were subjected for in vitro release and assay by HPLC-UV to assess long term stability. Single dose pharmacokinetic study used a single sequence three treatments crossover design. In Periods 1 and 2, four dogs received oral 20 mg dose of two prototype formulations. In Period 3, all dogs recieved a 20 mg oral dose of Aciphex reference product. There was a 1-wk washout time between two successive periods. A quant. anal. of rabeprazole/sulfide metabolite in plasma samples was performed using a validated LC-MS/MS assay and PK parameters were estimated by non-compartmental anal. The stability of the prototype formulations was confirmed over a period of 24 mo with an acceptable assay and dissolution data. One of the novel prototype formulations showed 70% oral bioavailability relative to the reference product. Despite a 30% reduced bioavailability, this showed 1 h delay in peak concentration, longer plasma residence time of rabeprazole (up to 12 h) and longer apparent elimination half-life. The use of a canine model has enabled the selection of a novel dual-release prototype formulation of rabeprazole for further clin. development.

[Dual therapy with rabeprazole and amoxicillin four times daily for 14 days for the first-line eradication of Helicobacter pylori infection]. was written by Suo, B J;Tian, X L;Li, C L;Song, Z Q. And the article was included in Zhonghua yi xue za zhi in 2019.Quality Control 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:

Objective: To investigate the efficacy, safety and compliance of dual therapy for the first-line eradication of Helicobacter pylori infection through a prospective, single-center and open-label cohort study. Methods: From March 2014 to September 2018, 200 naïve patients with Helicobacter pylori infection and dyspepsia received 14-day dual therapy (rabeprazole 10mg and amoxicillin 500 mg, four times daily orally). Safety and compliance were assessed 1-3 days after eradication. The therapeutic outcome was determined by (13)C-urea breath test 4-8 weeks after eradication. Some patients underwent strain culture, antibiotic sensitivity testing and CYP2C19 polymorphism assay. Results: The eradication rates of dual therapy: intention-to-treat analysis 87.5% (95% confidence interval 82.5%-91.5%), modified intention-to-treat analysis 90.2% (86.1%-94.3%) and per-protocol analysis 91.0% (86.3%-94.7). 21.2% of patients had adverse reactions, the majority were mild to moderate, and only 1.5% of patients discontinued medication because of intolerance to adverse reactions. Patients with good compliance accounted for 96.0%. Variate analyses showed that poor compliance and amoxicillin resistance were the independent risk factors for eradication failure. Conclusions: 14-day dual therapy with rabeprazole and amoxicillin (four times daily) achieved good efficacy, safety and compliance for the first-line eradication of Helicobacter pylori infection.

Dosing is a critical aspect of drug development in pediatrics that has led to trial failures and the inability to label the drug for pediatric use by the US Food and Drug Administration. Developing a structured approach for pediatric dose selection requires knowledge of the current approaches and their success or failure. This study describes the current experience with pediatric dosing methods from 2012 to 2020 and had 2 primary objectives: (1) to identify how the initial pediatric dose was selected and (2) to identify the pivotal dosing strategy used to identify the initially selected dose for safety and efficacy for pediatric clin. trials. Through Sept. 2020, a total of 275 pediatric drug development programs were characterized for initial and pivotal dosing strategies. The success rate for labeling for pediatric use was 76.4%. The most common initial dosing strategy was previous experience with the product, followed by allometric scaling and exposure matching with adults. The most common pivotal dosing strategy was titration to target response in 33% of programs, with the second and third most common being pharmacokinetic/pharmacodynamic studies (30%) and exposure matching (20%), resp. Addnl., about one-half of pediatric programs incorporated model-informed drug development. The emergence of titration to target response may signal a shift toward precision medicine in pediatric patients.

Long-term outcomes of elderly hairy cell leukemia patients treated with cladribine was written by Hermel, David J.;Cheng, Brian;Bhangoo, Munveer S.;Burian, Carol;Waalen, Jill;Saven, Alan. And the article was included in Annals of Hematology in 2022.Application of 16506-27-7 The following contents are mentioned in the article:

Hairy cell leukemia (HCL) is a rare hematol. disorder characterized by pancytopenia and splenomegaly for which a single course of cladribine is highly effective in inducing complete remissions. However, there is limited real-world data on outcomes and complications among geriatric patients with HCL treated with cladribine. We conducted a retrospective review of all patients 70 years or older within the Scripps Clinic HCL Database at the time of first treatment with cladribine. Of the 45 patients meeting inclusion criteria, 32 (71%) achieved CR and 4 (9%) achieved PR. Of the 9 remaining patients, 7 achieved normalization of peripheral blood counts after a single course of cladribine (complete hematol. response, CHR) and 2 had no response. The median duration of response for all responders was 119 mo. Nine (20%) patients relapsed with a median time to first relapse of 28 mo. Ten patients subsequently developed 12 primary malignancies with an excess frequency (observed-to-expected ratio) of 0.85 (95% confidence interval, 0.48-1.49). Median overall survival for the entire cohort was 166 mo from time of HCL diagnosis and 119 mo from time of first cladribine administration. Forty patient deaths were observed; the standardized mortality ratio (observed-to-expected ratio) was 1.42 (95% confidence interval, 1.03-1.96), representing a statistically significant increase in the risk of death (P = .03). This study supports the high rate of complete and durable responses following a single course of cladribine in geriatric patients.
