Introduction

Voxzogo (vosoritide) is a therapeutic indicated for the treatment of achondroplasia, the most common form of dwarfism. Approved by the U.S. Food and Drug Administration (FDA) in 2021, voxzogo’s active pharmaceutical ingredient (API), vosoritide, is a synthetic peptide that modulates the growth plate activity by targeting the cGMP pathway. As with any therapeutic, the quality, source, and reliability of bulk API suppliers are critical for manufacturers to ensure product consistency, regulatory compliance, and cost-effectiveness.

This article provides a comprehensive overview of the primary API sources for vosoritide, emphasizing the supply chain landscape, key manufacturing regions, and sourcing considerations for pharmaceutical companies.

Understanding Vosoritide and its API Composition

Vosoritide is a 39-amino acid peptide analog of C-type natriuretic peptide (CNP). Its synthesis involves complex peptide manufacturing processes, often through solid-phase peptide synthesis (SPPS). Consequently, sourcing high-quality amino acids and peptide synthesis services is integral to reliable API production.

API Production Process

The production of vosoritide involves several stages:

Peptide synthesis: Using SPPS, typically conducted by specialized peptide manufacturing facilities.
Purification and characterization: Ensuring the peptide’s purity meets regulatory standards.
Quality assurance: Rigorous testing to confirm identity, purity, and stability.

Given the peptide’s complexity, API sourcing often involves established peptide contract manufacturing organizations (CMOs) with facility accreditation.
