Comprehensive HPAPI CDMO Capabilities

Process Development for High Potent APIs

From route scouting to GMP commercial supply, we cover every stage of the high potent API lifecycle under one integrated, containment-controlled roof.

  • Project Assessment: Feasibility review of molecule, target market, regulatory landscape, existing IP position, and timeline goals
  • Route Scouting: Multi-route evaluation with comparative analysis of yields, costs, safety profiles, containment requirements, and raw material availability
  • Process Optimization: DoE-driven optimization, impurity profiling, genotoxic impurity control, and Quality-by-Design (QbD) implementation
  • Potency Assessment: Occupational exposure banding, hazard assessment, and containment strategy defined before scale-up begins
  • Analytical Development: Method development and validation in an independent analytical laboratory dedicated to high-potent compounds

Questions & Answers

Our FAQ's

An HPAPI CDMO is a contract development and manufacturing organization specialized in highly potent active pharmaceutical ingredients, compounds so potent that they are effective at very low doses and require dedicated containment. Shilpa Pharma provides end-to-end HPAPI CDMO services, from process development through commercial manufacturing, using isolator-based high-containment infrastructure across OEL Band 1 to 5.

Shilpa’s high-containment facilities are engineered to safely handle OEL Band 1 to 5 compounds. Each molecule is assessed and assigned an occupational exposure band during development, and containment design follows the assigned band.

Yes. Shilpa manufactures cytotoxic oncology APIs, including tyrosine kinase inhibitors, alkylating agents, and antimetabolites, as well as non-oncology high-potent compounds such as hormonal and immunosuppressant molecules.
