FDA Approved Drugs: Changes to Approved Drugs

269
Post-approval, manufacturers may modify an approved new or generic drug product. Such modifications can encompass alterations in the Active Pharmaceutical Ingredient (API), manufacturing process, formulation, batch size, manufacturing site, and container closure system (FDA Guidance for Industry, April 2004). Often, a drug product may undergo multiple changes.These modifications require careful evaluation to determine their potential impact on the drug product's identity, strength, quality,...

Global Climate Change

28.9K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Introduction to Global Positioning System

516
The Global Positioning System (GPS) revolutionized positioning on Earth, providing precise location data through satellite ranging. The GPS system was developed in 1978 by the U.S. Department of Defense  for military use, and it became available for civilian applications in 1983, transforming fields including navigation, fleet management, and time synchronization for telecommunications systems.GPS consists of satellites in medium Earth orbit, about 20,200 kilometers above the surface,...

Errors in Global Positioning System

354
Global Positioning System (GPS) technology has revolutionized navigation and positioning, but its accuracy is often compromised by various errors. These errors, stemming from environmental, satellite, and receiver-related factors, require careful mitigation to ensure reliable performance across applications.Atmospheric ErrorsGPS signals travel through the Earth’s ionosphere and troposphere, introducing delays which affect accuracy. The ionosphere is strongly influenced by charged particles,...

Global Regulatory Systems

677
Global regulatory systems in bacteria enable rapid and coordinated responses to environmental changes by integrating sensory inputs with gene expression, ensuring efficient adaptation to fluctuating conditions. Key global regulatory mechanisms include regulons, two-component systems, sigma factors, and secondary messengers.Regulons and Global RegulatorsA regulon is a collection of genes and operons controlled by a common global regulator. These regulators enable bacteria to prioritize resource...

Area of Science:

  • Oncology
  • Pharmacology
  • Genetics

Background:

  • Talazoparib is an oral poly(ADP-ribose) polymerase (PARP) inhibitor.
  • PARP enzymes are crucial for DNA single-strand break repair.
  • Pfizer developed talazoparib (TALZENNA™).

Purpose of the Study:

  • To summarize the development milestones of talazoparib.
  • To highlight its initial FDA approval for a specific breast cancer subtype.

Main Methods:

  • Review of talazoparib's development pathway.
  • Analysis of its regulatory approval process.

Main Results:

  • Talazoparib received US FDA approval.
  • Approval is for adults with deleterious or suspected deleterious germline BRCA-mutated, HER2-negative, locally advanced or metastatic breast cancer.

Conclusions:

  • Talazoparib represents a significant advancement in targeted therapy for BRCA-mutated breast cancer.
  • Ongoing development explores its use in prostate cancer, other solid tumors, and neoadjuvant therapy for triple-negative breast cancer.
