Introduction
Capivasertib, also known as AZD5363, is an investigational oral kinase inhibitor primarily targeting the AKT pathway, a crucial player in cell proliferation and survival often dysregulated in cancers. Developed by AstraZeneca, it has advanced through clinical trials for various cancer types, including breast, prostate, and ovarian cancers. The complex synthesis process, high purity requirements, and intellectual property protections influence its supply chain. This article delineates key suppliers involved in the manufacturing, synthesis, formulation, and supply of capivasertib, providing essential insights into the sourcing landscape for industry stakeholders.
Manufacturing and Raw Material Suppliers
Active Pharmaceutical Ingredient (API) Producers
The supply of capivasertib hinges upon high-quality manufacturing of its active pharmaceutical ingredient (API). Given its novelty and patent status, only a selected consortium of specialized API manufacturers produce capivasertib under strict regulatory compliance.
AstraZeneca’s In-House Manufacturing
AstraZeneca maintains a controlled supply of capivasertib via its proprietary manufacturing facilities, ensuring quality and supply continuity during clinical development. Their in-house production adheres to Good Manufacturing Practice (GMP) standards, minimizing contamination risks and ensuring consistency.
Contract Manufacturing Organizations (CMOs)
In addition to internal production, AstraZeneca collaborates with CMOs to scale up manufacturing and meet increasing clinical trial demands. Notable CMOs with capabilities in complex synthesis and high-potency APIs include:
