Nadofaragene Firadenovec-Vncg

Brand Names: Adstiladrin

Drug Class: General Prescription

Overview

11 DESCRIPTION ADSTILADRIN (nadofaragene firadenovec-vncg) is a non-replicating adenoviral vector-based gene therapy for intravesical instillation. It is a recombinant adenovirus serotype 5 vector containing a transgene encoding the human interferon alfa-2b (IFNα2b). ADSTILADRIN has a nominal concentration of 3 x 10 11 vp/mL.

Mechanism of Action

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action ADSTILADRIN is a non-replicating adenoviral vector-based gene therapy designed to deliver a copy of a gene encoding a human interferon-alfa 2b (IFNα2b) to the bladder urothelium. Intravesical instillation of ADSTILADRIN results in cell transduction and transient local expression of the IFNα2b protein that is anticipated to have anti-tumor effects. 12.2 Pharmacodynamics A Phase 1 first-in-human study was performed to determine the safety, tolerability, and maximum tolerated dose (MTD) of ADSTILADRIN in 17 patients with BCG-unresponsive NMIBC.
