Bulk Active Pharmaceutical Ingredient (API) Sources for Caprelsa

Last updated: July 29, 2025

Introduction

Caprelsa (vandetanib) is an oral tyrosine kinase inhibitor used primarily in the treatment of medullary thyroid carcinoma (MTC), including unresectable or metastatic cases. As an essential therapeutic agent, the consistent supply of high-quality Active Pharmaceutical Ingredient (API) is critical for manufacturing, regulatory compliance, and maintaining market stability. This report analyzes the global landscape of bulk API sourcing for Caprelsa, emphasizing key manufacturers, geographic distribution, supply chain dynamics, and emerging trends.

Overview of Caprelsa API Production

Vandetanib, the API in Caprelsa, is a complex molecule synthesized through multi-step chemical processes. The manufacturing complexity influences API sourcing, emphasizing the importance of quality, regulatory adherence, and supply consistency. The API's production involves advanced synthesis techniques, strict quality controls, and adherence to Good Manufacturing Practices (GMP).

Major API producers supply to branded drug manufacturers and generic drug companies worldwide. The sourcing landscape is characterized by a distribution of high-capacity API manufacturers primarily located in North America, Europe, and Asia.

Leading API Manufacturers for Vandetanib (Caprelsa)

1. Sanofi’s In-house Production

   Sanofi, the originator of Caprelsa, internally produces the API to safeguard supply chain security and ensure quality compliance. The company's integrated manufacturing facilities, primarily located in Europe and North America, control the API supply chain to meet global demand. Sanofi invests significantly in R&D and quality systems to optimize API synthesis and meet regulatory requirements.

2. Contract Manufacturing and Outsourcing

   Over recent years, Sanofi has leveraged Contract Development and Manufacturing Organizations (CDMOs) for API supply, facilitating capacity expansion and cost control.

   • Lonza (Switzerland): A leading CDMO with established expertise in complex APIs. Lonza's capabilities in custom synthesis and high-quality API production make it a key partner in the supply chain for oncology APIs, including vandetanib.

   • CordenPharma (Germany): Specializes in GMP manufacturing of niche APIs and intermediates, offering scalable manufacturing for clinical and commercial sources.

   • Li Tong Pharmaceutical (China): A growing API manufacturer producing vandetanib API for global markets, particularly Asia. Li Tong emphasizes cost-effective, GMP-compliant manufacturing, catering to regional demand.

3. Emerging Suppliers and Markets

   • Asian API manufacturers, particularly in China and India, are increasing production capabilities to meet growing demand for oncology APIs. Companies such as Zhejiang Huahai Pharmaceutical and Hetero Labs are expanding their API portfolios and manufacturing capacities for targeted therapies.

   • These emerging suppliers benefit from lower manufacturing costs but face regulatory challenges to ensure compliance with international standards, such as US FDA and EMA approvals.

4. Regulatory and Quality Considerations

   Ensuring API sourcing from GMP-compliant facilities is paramount. Both Sanofi and third-party manufacturers undergo rigorous regulatory scrutiny by agencies like the FDA, EMA, and PMDA to maintain drug approval status.

   The shift towards diversified sourcing aims to mitigate supply risks and ensure compliance with global regulatory standards.

Supply Chain Dynamics and Risks

• Geographic Concentration and Diversification:
  While the majority of high-quality API production occurs in Europe and North America, increasing reliance on Asian suppliers introduces risk but offers balancing options for cost and capacity.

• Regulatory Challenges:
  Suppliers outside established markets must demonstrate compliance with international standards, which may entail delays and verification processes, impacting supply timelines.

• Manufacturing Scale and Capacity:
  Producing vandetanib API at commercial scale requires substantial investment in synthesis infrastructure. Capacity constraints have appeared in certain regions, prompting manufacturers to expand or upgrade facilities.

• Intellectual Property and Exclusivity:
  As a drug developed and owned by Sanofi, API manufacturing is tightly controlled, with licensing and rights ensuring supply exclusivity. However, the presence of authorized generic manufacturers indicates some degree of API licensing and distribution.

Emerging Trends and Future Outlook

• Shift Toward Regional API Production:
  Countries such as China, India, and Eastern European nations are boosting their API manufacturing footprint, aiming to capture a larger share of the oncology API market.

• Technological Advances:
  Process optimization, continuous manufacturing, and synthetic route improvements are poised to lower costs and increase efficiency.

• Regulatory Harmonization:
  As international standards become more aligned, API suppliers can expand global distribution channels with greater confidence.

• Risk Management Strategies:
  Pharma companies increasingly adopt dual or multiple API sourcing strategies to enhance supply security amid geopolitical and logistical uncertainties.

Conclusion

The API sourcing landscape for Caprelsa (vandetanib) is evolving, with Sanofi maintaining primary control through in-house manufacturing and strategic partnerships. The reliance on capable CDMOs like Lonza and CordenPharma supports scalable and compliant production. The rising contribution of Asian API manufacturers signifies both opportunities for cost-effective supply and challenges associated with regulatory compliance. Maintaining a diverse, transparent supply chain remains critical for securing stable API availability to meet the global demand for medullary thyroid carcinoma treatment.
