Fabry disease (FD) is a rare lysosomal storage disorder that is associated with pain and progressive damage to the renal, cardiac, and cerebrovascular systems. Enzyme replacement therapy (ERT) is one of the treatment options for FD and the most recently approved ERT agent, pegunigalsidase alfa, has shown clinical efficacy in three phase 3 clinical...

Aim Insufficient adherence to colorectal cancer (CRC) screening impedes individual and population health benefits, with about one-third of individuals non-adherent to available screening options. The impact of poor adherence is inadequately considered in most health economics models, limiting the evaluation of real-world population-level screening...

Immunocompromised host pneumonia (ICHP) is an important cause of morbidity and mortality, yet usual care (UC) diagnostic tests often fail to identify an infectious etiology. A US-based, multicenter study (PICKUP) among ICHP patients with hematological malignancies, including hematological cell transplant recipients, showed that plasma microbial cel...

Materials & methods: Four trials in previously treated metastatic non-small-cell lung cancer with PD-L1 >1% were used comparing docetaxel with nivolumab, pembrolizumab and atezo...
Article
Full-text available
Importance: Platform trial design allows the introduction of new interventions after the trial is initiated and offers efficiencies to clinical research. However, limited guidance exists on the economic resources required to establish and maintain platform trials. Objective: To compare cost (US dollars) and time requirements of conducting a plat...

Background and aims Effective acid suppression is a crucial component of Helicobacter pylori (H. pylori) eradication regimens. Approved treatments include dual, triple, and quadruple therapies composed of certain antibiotics in combination with proton pump inhibitors (PPIs). Vonoprazan, a potassium-competitive acid blocker, provides more potent and...
Article
Full-text available
Progression-free survival (PFS) is a common primary endpoint in newly diagnosed multiple myeloma (NDMM). Patients with NDMM typically have longer PFS and are more likely to achieve minimal residual disease (MRD) or complete response (CR) compared to patients with relapsed or refractory multiple myeloma. Response-based surrogate endpoints may hold v...

Importance: Sexual orientation and gender identity change efforts (SOGICE), also called conversion therapy, is a discredited practice attempting to convert lesbian, gay, bisexual, transgender, queer, or questioning (LGBTQ) individuals to be heterosexual and/or cisgender. Objectives: To identify and synthesize evidence on the humanistic and econo...
Article

Aims: To compare clinical trial results for crizotinib and entrectinib in ROS1-positive non-small-cell lung cancer and compare clinical trial data and real-world outcomes for crizotinib. Patients & methods: We analyzed four phase I–II studies using a simulated treatment comparison (STC). A STC of clinical trial versus real-world evidence compared c...
Article
Introduction: Myelofibrosis (MF) is a Philadelphia chromosome-negative myeloproliferative neoplasm with an estimated prevalence of 4-6/100,000 persons in the USA. Patients with MF experience aberrant hematopoiesis, bone marrow fibrosis, splenomegaly, and cytopenias, including thrombocytopenia, as well as diminished survival ranging from months to y...
Article
Full-text available
Background Selinexor is an oral, selective nuclear export inhibitor. STORM was a phase 2b, single-arm, open-label, multicenter trial of selinexor with low dose dexamethasone in patients with penta-exposed relapsed/refractory multiple myeloma (RRMM) that met its primary endpoint, with overall response of 26% (95% confidence interval [CI], 19 to 35%)...
Article
Full-text available
Background: Despite the availability of new treatments, multiple myeloma (MM) is an incurable cancer with nearly all patients relapsing and undergoing multiple lines of treatment. Performing head-to-head comparisons of all treatment options is not feasible. Thus, network meta-analyses play an important role in allowing health-care decision makers t...
Article
Full-text available
Background and Objective Nearly all patients with multiple myeloma undergo multiple rounds of therapy. The phase III BOSTON trial of once-weekly selinexor and once-weekly bortezomib with dexamethasone (XVd) vs twice-weekly bortezomib and dexamethasone (Vd) is the basis for this cost-effectiveness analysis in previously treated multiple myeloma from...
