Bulk Active Pharmaceutical Ingredient (API) Sources for: Enzalutamide

Last updated: July 27, 2025

Introduction

Enzalutamide, marketed primarily under the brand name Xtandi, is a non-steroidal anti-androgen medication used to treat metastatic castration-resistant prostate cancer (mCRPC). It functions by inhibiting androgen receptor signaling pathways, thereby impeding tumor growth. As a critical therapeutic agent, the demand for high-quality enzalutamide API continues to rise globally, driven by expanding indications and patient needs. Securing reliable sources for bulk enzalutamide API is essential for pharmaceutical manufacturers, generic drug producers, and research institutions.

This comprehensive review details the primary API suppliers for enzalutamide, evaluates their manufacturing capabilities, quality standards, regulatory compliance, and geographic presence. It aims to guide stakeholders in sourcing high-quality enzalutamide API sustainably and cost-effectively.

Overview of Enzalutamide API Market

The global enzalutamide market is characterized by a small but strategically significant API segment, primarily supplied by a mix of innovator companies, generic manufacturers, and contract manufacturing organizations (CMOs). Due to patent protections, initial supply was dominated by the originator company, but generic and API supplier markets are now expanding as patents expire or licensing agreements are established.

Key factors influencing API sourcing include regulatory compliance (FDA, EMA, PMDA), manufacturing capacity, quality control, and geopolitical stability of supply regions. As the drug becomes more widely adopted, the API supply chain has diversified to mitigate risks and ensure steady production.

Regulatory and Quality Considerations

Securing API from reputable sources necessitates adherence to stringent quality standards. Suppliers must demonstrate compliance with international GMP standards, along with detailed documentation, stability data, and validated manufacturing processes. For global distribution, APIs must be compliant with regional regulatory requirements, such as FDA 21 CFR Part 211 in the U.S. and equivalence standards in Europe (EudraLex).

Additionally, Certificates of Analysis (CoA), GMP certificates, and dossiers verifying the purity and residual impurities are essential for validation.
