AI Article Synopsis

  • - Geographic atrophy (GA) is a serious form of age-related macular degeneration (AMD) that causes significant vision loss, creating a need for new treatment methods since traditional options are limited.
  • - The article reviews investigational drugs aimed at inhibiting the complement system, focusing on two recently FDA-approved drugs: pegcetacoplan (a C3 complement inhibitor) and avacincaptad pegol (a C5 complement inhibitor) with insights on their effectiveness and safety.
  • - While the FDA's approval of these drugs represents a major advancement in GA treatment, inconsistent clinical trial results highlight the complexity of GA and the necessity for careful patient selection and further research to improve treatment outcomes.

Article Abstract

Introduction: Geographic atrophy (GA) is a progressive form of age-related macular degeneration (AMD) that leads to severe visual impairment and central vision loss. Traditional treatment options for GA are limited, highlighting the need for new therapeutic approaches. In recent years, targeting the complement system has emerged as a promising strategy for the treatment of GA.

Areas Covered: This expert opinion article reviews the investigational drugs inhibiting the complement cascade for the treatment of GA. Specifically, it focuses on the recent FDA approved pegcetacoplan, a C3 complement inhibitor, and avacincaptad pegol, a C5 complement inhibitor, highlighting their potential efficacy and safety profiles based on clinical trial data.

Expert Opinion: FDA approval of intravitreal pegcetacoplan and avacincaptad pegol marks significant progress in the landscape of GA treatment. However, variable results from trials underscore the complex nature of GA and the importance of patient selection. Complement inhibition holds promise, but ongoing research is vital to refine treatment strategies and offer improved outcomes for GA patients.

Glioblastoma multiforme (GBM) is the most common and aggressive primary brain tumor in adults, characterized by resistance to conventional therapies and poor survival. Ferroptosis, a form of regulated cell death driven by lipid peroxidation, has recently emerged as a promising therapeutic target for GBM treatment. However, there are currently no non-invasive imaging techniques to monitor the engagement of pro-ferroptotic compounds with their respective targets, or to monitor the efficacy of ferroptosis-based therapies.

Individuals with certain primary immunodeficiency disorders (PID) may be unable to clear poliovirus infection after exposure to oral poliovirus vaccine (OPV). Over time, vaccine-related strains can revert to immunodeficiency-associated vaccine-derived poliovirus (iVDPVs) that can cause paralysis in the patient and potentially spread in communities with low immunity. We reviewed the efforts for detection and management of PID patients with iVDPV infections and the epidemiology through an analysis of 184 cases reported to the World Health Organization (WHO) during 1962-2024 and a review of polio program and literature reports.

Clinical Features: Sickle cell patients may develop a multitude of antibodies and experience life-threatening events with transfusion such as hyperhemolysis syndrome or delayed hemolytic transfusion reaction. Further transfusion may not be possible in such cases.

Therapeutic Challenge: When conventional blood products are not available for transfusion yet the patient requires additional oxygen-carrying support, artificial oxygen carriers may be required.

Programs allowing access to investigational drugs and off-label drug use for serious diseases have often been applied to pediatric cancers. A clinical study conducted under the Japanese "Patient-Proposed Healthcare Services" evaluated the efficacy and safety of dabrafenib plus trametinib in children with BRAF V600 mutant glioma (jRCTs071210071). This study successfully provided unapproved and off-label medications to four enrolled patients, two with low-grade glioma and two with high-grade glioma (median age: 10.

  • Type I and mixed cryoglobulinemic vasculitis have different causes, symptoms, and treatment responses, with a reported case of refractory vasculitis linked to ischemic non-obstructive coronary artery disease.
  • The patient exhibited severe symptoms including dyspnea, abdominal pain, purpura, and renal failure requiring dialysis, with diagnostic markers suggesting mixed cryoglobulinemia.
  • Despite various treatments failing initially, bortezomib and dexamethasone successfully led to clinical improvement and cryoglobulin negativity, indicating bortezomib's potential as an effective therapy for this challenging condition.
