Bulk API Sources for Aliqopa (Copanlisib)

Last updated: August 7, 2025

Introduction

Aliqopa (copanlisib) is an orally administered, PI3K-alpha and delta inhibitor approved for the treatment of relapsed follicular lymphoma after at least two prior systemic therapies. As a targeted cancer therapy, copanlisib’s manufacturing relies heavily on high-quality bulk Active Pharmaceutical Ingredient (API) sources, ensuring efficacy, safety, and regulatory compliance. This article explores the key APIs suppliers, manufacturing considerations, and sourcing strategies for copanlisib, providing critical insights for pharmaceutical companies, contract manufacturing organizations (CMOs), and stakeholders involved in its supply chain.

Overview of Copanlisib and API Significance

Copanlisib’s complex chemical structure, a selective phosphoinositide 3-kinase (PI3K) inhibitor, demands a sophisticated synthesis process. The API’s purity and consistency directly influence drug efficacy, safety profiles, and regulatory approval. Given its indications for oncology, the API must meet strict quality standards, including Good Manufacturing Practice (GMP) compliance, stability, and traceability.

API Sourcing: Strategic and Operational Considerations

The sourcing of copanlisib API encompasses several strategic factors:

• Quality Assurance (QA) & Quality Control (QC): Ensuring APIs are manufactured in certified facilities adhering to GMP standards.
• Supply Reliability: Building relationships with trusted suppliers to prevent shortages.
• Cost Effectiveness: Balancing quality and pricing for sustainable supply.
• Regulatory Compliance: Suppliers must provide validated manufacturing processes and documentation for regulatory audits, especially for submission in major markets like the US, EU, and Japan.
• Intellectual Property (IP): Clarifying licensing agreements and patent obligations.

Key API Suppliers for Copanlisib

While global API manufacturing is concentrated mainly in countries with established pharmaceutical sectors such as India, China, and Europe, the complexity of copanlisib’s synthesis limits the number of qualified API producers.

1. Contract Manufacturing Organizations (CMOs) and API manufacturers

Some notable manufacturers with experience in complex oncology APIs are:

• Synthesis Pharma (India): Known for robust synthetic capabilities, Synthesis Pharma offers GMP-certified APIs, including custom synthesis for kinase inhibitors.
• Dr. Reddy’s Laboratories (India): A leading pharmaceutical company with extensive API manufacturing infrastructure. Dr. Reddy’s has experience with oncology APIs and can support copanlisib’s requirements.
• WuXi AppTec (China and Europe): A comprehensive provider of APIs and early-stage development, WuXi offers scalable synthesis capabilities aligned with international GMP standards.
• F. Hoffmann-La Roche (Switzerland): While primarily a pharmaceutical manufacturer rather than an API supplier, Roche has engaged in API licensing and development collaborations, potentially providing high-quality APIs under licensing agreements.
• Boehringer Ingelheim (Germany): Specializes in complex APIs; may serve as an OEM API provider for specific oncology compounds.

2. Licensed API Suppliers and Licensed Manufacturing

Partnerships with licensed API manufacturers may involve licensing agreements from innovator companies or licensing of synthesis patents, depending on where copanlisib’s synthesis patents are held. These agreements often entail strict quality oversight, confidentiality, and supply commitments.

Synthesis Route and API Manufacturing Implications

The synthesis of copanlisib involves multiple steps with complex chemistry, including heterocyclic formation, chiral centers, and functional group modifications. The manufacturing process dictates the choice of API supplier; manufacturers with expertise in heterocyclic chemistries and complex small molecules are preferred.

The synthesis route typically involves:

• Multi-step organic synthesis with high stereochemical control.
• Stringent purification and crystallization steps.
• Analytical validation to confirm API purity (>99%) and absence of process-related impurities.

Manufacturers with advanced process development capabilities are better positioned to deliver consistent API quality in large batches, critical for meeting global regulatory standards.

Regulatory and Sourcing Challenges

The exclusivity rights and patent landscapes impact API sourcing. Manufacturers must demonstrate compliance through comprehensive documentation, including:

• Process validation data
• Analytical method validation
• Stability testing reports
• Batch records and traceability

Additionally, supply chain disruptions—such as geopolitical issues, raw material scarcity, or quality deviations—pose risks. Diversification of API sources and early engagement with multiple vendors mitigate such risks.

---

Global Market Perspective and Future Outlook

Given the growth of targeted oncology therapies, the demand for APIs like copanlisib is expected to increase. Manufacturers investing in process chemistry innovations and scalable manufacturing techniques will likely become preferred suppliers. Strategic partnerships, licensing agreements, and domestic production initiatives, especially within the US and Europe, may influence future sourcing options.
