Article Synopsis
  • Ruxolitinib cream, shown to be safe and effective in a phase 3 study, has demonstrated its anti-inflammatory and itch-relieving properties in children aged 2-11 with mild to moderate atopic dermatitis (AD).
  • The study focused on assessing safety, tolerability, pharmacokinetics, and quality of life while using the cream at maximum levels over longer periods, with 29 children participating and applying the cream twice daily for 4 weeks, followed by individualized usage.
  • Results indicated that 31% of participants experienced treatment-related adverse events, but no severe health issues arose, and significant improvements in skin condition and quality of life were sustained for up to 52 weeks.

Article Synopsis
  • Atopic dermatitis (AD) significantly affects patients' quality of life, causing itching, skin pain, and sleep disturbances; ruxolitinib cream has shown effectiveness in treating these symptoms in adults and adolescents through two phase III clinical trials.
  • In the TRuE-AD studies, patients applied different strengths of ruxolitinib cream or a vehicle cream, with results indicating that those using ruxolitinib experienced quick relief from symptoms like skin pain and sleep issues within hours or weeks of application.
  • Analysis of patient-reported outcomes revealed notable improvements in overall quality of life and symptom burden after two weeks of using ruxolitinib cream compared to the vehicle, with sustained benefits observed throughout the study periods.

Article Synopsis
  • In a study involving 1,249 patients, most experienced significant improvements in their condition with the cream, with over 70% achieving a low severity status after long-term use.
  • Safety profiles were positive, with treatment-related adverse events being minor, affecting less than 3% of patients across different medication groups.

Article Synopsis
  • Ruxolitinib cream shows promising efficacy as a systemic treatment for patients with moderate to extensive atopic dermatitis (AD), achieving notable anti-itch and anti-inflammatory effects compared to standard topical treatments.
  • In a study involving 1249 patients, a specific subgroup with higher disease severity experienced significant improvements, with 59.4% of those using ruxolitinib cream achieving treatment success by week 8.
  • The long-term safety profile was positive, with minimal side effects reported among patients, suggesting that ruxolitinib cream is a viable option for patients with more severe AD.

Article Synopsis
  • Atopic dermatitis (AD) affects around 7% of adolescents worldwide, and a new topical cream containing ruxolitinib (a JAK 1/JAK2 inhibitor) showed promise in treating this condition in two phase 3 trials.
  • The study focused on patients aged 12-17 and assessed the safety and effectiveness of 1.5% ruxolitinib cream compared to a placebo, with evaluations at the 8-week mark and during a long-term safety period of up to 52 weeks.
  • Results indicated that a significant portion of participants using the 1.5% cream experienced substantial improvements in skin condition and itchiness, with 89% choosing to continue the treatment in the long-term

Ruxolitinib (selective Janus kinase [JAK] 1 and JAK2 inhibitor) cream demonstrated efficacy and safety in patients with atopic dermatitis (AD) in the phase 3 TRuE-AD studies. In TRuE-AD1/TRuE-AD2 (NCT03745638/NCT03745651), adults and adolescents with mild to moderate AD were randomized to apply twice-daily ruxolitinib cream or vehicle for eight weeks. Here, we evaluated the efficacy and tolerability of ruxolitinib cream by anatomic region, focusing on head/neck (HN) lesions that are typically difficult to manage and disproportionately affect quality of life (QoL).

Ruxolitinib cream is a topical formulation of ruxolitinib, a selective inhibitor of Janus kinase (JAK) 1 and JAK2. In two phase 3 studies in adults and adolescents (aged ≥12 years) with atopic dermatitis (AD; TRuE-AD1/TRuE-AD2), significantly more patients who applied ruxolitinib cream versus vehicle cream achieved Investigator's Global Assessment treatment success (IGA-TS; IGA score of 0/1 with ≥2-point improvement from baseline) at week 8 (primary endpoint). This post hoc analysis evaluated the efficacy, safety, and disease control of ruxolitinib cream in patients with AD who did not achieve IGA-TS at week 8.

Background: Ruxolitinib cream demonstrated safety and efficacy over 8 weeks in 2 double-blind phase 3 atopic dermatitis studies (NCT03745638/NCT03745651).

Objective: To evaluate long-term safety (LTS) and disease control with ruxolitinib cream.

Methods: Patients initially randomized to twice-daily 0.

Purpose: Camrelizumab inhibits PD-1 in non-clinical models and showed typical non-clinical pharmacokinetic (PK) and safety profiles for an IgG4 monoclonal antibody. We report results from the First-in-Human Phase 1 trial of camrelizumab in Australian population.

Methods: Camrelizumab was administered to patients with advanced solid tumors who had failed standard therapies.

This phase I/II single-arm study evaluated the safety, pharmacokinetics, pharmacodynamics, and activity of foretinib, an oral multikinase inhibitor of MET, ROS, RON, AXL, TIE-2, and VEGFR2, in the first-line setting in advanced hepatocellular carcinoma patients. In the phase I part, advanced hepatocellular carcinoma patients were dose escalated on foretinib (30-60 mg) every day using the standard 3+3 design. Once the maximum tolerated dose (MTD) was determined, an additional 32 patients were dosed at the MTD in the phase II expansion cohort for assessment of efficacy and safety.

Foretinib is a multikinase inhibitor that inhibits multiple receptor tyrosine kinases, including MET and VEGFR, with the potential for treatment of solid tumors. Hepatocellular carcinoma (HCC) pathogenesis is associated with overexpression of MET, and physiologic changes in the livers of HCC patients may decrease CYP3A isozyme-mediated metabolism of foretinib. A population pharmacokinetic model of foretinib was developed to explore the effect of tumor type, formulation, and other covariates.

Purpose: The receptors for hepatocyte and vascular endothelial cell growth factors (MET and VEGFR2, respectively) are critical oncogenic mediators in gastric adenocarcinoma. The purpose is to examine the safety and efficacy of foretinib, an oral multikinase inhibitor targeting MET, RON, AXL, TIE-2, and VEGFR2 receptors, for the treatment of metastatic gastric adenocarcinoma.

Patients And Methods: Foretinib safety and tolerability, and objective response rate (ORR) were evaluated in patients using intermittent (240 mg/day, for 5 days every 2 weeks) or daily (80 mg/day) dosing schedules.

Background: Foretinib is a small-molecule, oral multikinase inhibitor primarily targeting the mesenchymal epithelial transition (MET) factor receptor, and the vascular endothelial growth factor receptor 2. We conducted a phase II study to evaluate the single-agent activity and tolerability of foretinib in patients with recurrent/metastatic squamous cell carcinoma of the head and neck (SCCHN).

Methods: An open-label, single-arm, multicenter trial employing a Simon 2-stage design was conducted with a total of 41 patients planned for the study.

Tuberculosis remains a global health problem, and programs dedicated to discovery of novel compounds against Mycobacterium tuberculosis require robust assays for high-throughput screening of chemical and natural product libraries. Enzymes involved in the biosynthesis of mycolic acids, vital components of the mycobacterial cell wall, have received much attention as potential drug targets. KasA and KasB, examples of the beta-ketoacyl-acyl carrier protein synthase I/II (KASI/II) class of condensing enzymes of the M.

3-Hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) synthase, a member of the family of acyl-condensing enzymes, catalyzes the first committed step in the mevalonate pathway and is a potential target for novel antibiotics and cholesterol-lowering agents. The Staphylococcus aureus mvaS gene product (43.2 kDa) was overexpressed in Escherichia coli, purified to homogeneity, and shown biochemically to be an HMG-CoA synthase.
