Lurbinectedin (Mechanism of Action)

In this article we will discuss Lurbinectedin (Mechanism of Action)

In this article, we will discuss Lurbinectedin (Mechanism of Action). So, let’s get started.

Lurbinectedin is an alkylating drug that binds guanine residues in the minor groove of DNA, forming adducts and resulting in a bending of the DNA helix towards the major groove. Adduct formation triggers a cascade of events that can affect the subsequent activity of DNA binding proteins, including some transcription factors, and DNA repair pathways, resulting in perturbation of the cell cycle and eventual cell death. Lurbinectedin inhibited human monocyte activity in vitro and reduced macrophage infiltration in implanted tumors in mice.

Lurbinectedin exposure-response relationships and the pharmacodynamic time-course for efficacy have not been fully characterized. Increased incidence of Grade 4 neutropenia and Grade ≥ 3 thrombocytopenia were observed with
increased lurbinectedin exposure.
Cardiac Electrophysiology No large mean increase in QTc (i.e. > 20 ms) was detected following treatment with Lurbinectedin at the recommended dose of 3.2 mg/m2.
