HPAPI manufacturing

Axplora ADC payloads development and manufacturing

The demand for Highly Potent Active Pharmaceutical Ingredients (HPAPIs) is growing steadily, driven by the need for targeted medicines in the oncology field.

An HPAPI is usually defined as an API with an occupational exposure limit (OEL) at/or below 10 µg/m³ of air as an 8-h time-weighted average.
Due to the risks associated with their high pharmacological activity, the development and manufacturing of HPAPIs must ensure the safety of both patients and employees. This requires a strong quality system and HSE culture, and specialized high containment facilities operated by experienced personnel.
By nature, HPAPIs are often complex molecules and need specialized technologies for multi-step synthesis and purification.

Recognized expertise in HPAPI manufacturing

Axplora has a proven track record in the development and commercial manufacturing of HPAPIs with more than 300 commercial & clinical cGMP batches produced.

Our Le Mans site located in France, and our Gropello site in Italy, are centers of excellence for highly potent APIs. These sites offer more than 30 years’ experience in the manufacturing of HPAPIs & cytotoxic.

When our Le Mans site provides specific expertise in the field of ADC payloads, in addition to ADC conjugation services, our Gropello site offers services for steroids, cytotoxic, and other HPAPIs.

Handling of HPAPIs

Our Le Mans site can handle highly potent compounds with an OEL below 10 ng/m³/8hrs & cytotoxic with a maximum batch size of 10 kgs and our Gropello site can handle highly potent compounds with an OEL up to 10 ng/m³/8hrs.

Potent compounds, between 1-10 μg/m³/8hrs, can be manipulated at Axplora Gropello (Italy) and Chasse-sur-Rhône (France) with a batch size of up to 350 kgs.

We are able to handle a wide range of chemistry. Low and high-temperature reactions, as well as reduction or oxidation processes, can be run in our HPAPI facilities.
