Tixagevimab-Cilgavimab: COVID-19 Pre-Exposure Prophylaxis
1Prisma Health Cancer Institute.
Clinical Journal of Oncology Nursing
|September 15, 2022
Summary
Tixagevimab-cilgavimab offers COVID-19 prevention for immunocompromised individuals. This nonvaccine therapy is authorized for those unable to receive COVID-19 vaccines.
Area of Science:
- Immunology
- Virology
- Pharmacology
Background:
- COVID-19 poses significant risks to immunocompromised populations.
- Vaccine efficacy may be reduced in moderately to severely immunocompromised individuals.
- Alternative prevention strategies are crucial for vulnerable groups.
Purpose of the Study:
- To evaluate the role of tixagevimab-cilgavimab in preventing COVID-19 infection.
- To assess the efficacy of tixagevimab-cilgavimab as a nonvaccine prophylactic agent.
- To determine the suitability of tixagevimab-cilgavimab for individuals unable to receive COVID-19 vaccines.
Main Methods:
- Review of current authorizations and clinical data.
- Analysis of tixagevimab-cilgavimab's mechanism of action.
- Assessment of patient populations eligible for this treatment.
Main Results:
- Tixagevimab-cilgavimab is the sole nonvaccine drug authorized in the U.S. for COVID-19 prevention.
- It is indicated for individuals with moderate to severe immunocompromise.
- Eligibility also extends to those unable to receive COVID-19 vaccines.
Conclusions:
- Tixagevimab-cilgavimab provides a vital preventive option for specific high-risk populations.
- This monoclonal antibody therapy addresses a critical unmet need in COVID-19 prophylaxis.
- Its authorization expands therapeutic choices for immunocompromised individuals.

Transmission-based Precautions I: Contact, Enteric, and Droplets
3.9K
Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...

Subviral Agents
84
Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...

Transmission-based Precautions II: Airborne and Protective Environment
1.4K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Pulmonary Tuberculosis IV
188
Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

Preclinical Development: Overview
4.7K
Preclinical development consists of a series of tests that ensure the safety and efficacy of a new therapeutic compound before it is tested in humans. There are four main phases to this process. First, safety pharmacology tests are conducted to ensure the drug does not produce any acutely harmful effects. These tests examine parameters such as bronchoconstriction, cardiac dysrhythmias, blood pressure changes, and ataxia. Next, preliminary toxicological testing is performed to determine the...

Sexually Transmitted Infections
403
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
