## Summary

In a recent procurement process, CELL THERAPY CATAPULT LIMITED has completed the direct award of a contract for the purchase of Non-GMP Alternating Tangential Flow (ATF) equipment. This equipment is integral to supporting the development of processes that will transition to GMP Manufacturing, specifically for the Ena Biologics BMIC Project. The procurement, initiated on 15th July 2026, is categorised under biomedical equipment and repair and maintenance services of medical and precision equipment. The entire contract, valued at €345,878.40, is set to commence on 1st September 2026 and will run until 1st September 2027. CELL THERAPY CATAPULT LIMITED, located in London, UK, awarded this contract to Repligen B.V, a supplier based in the Netherlands.

This tender presents substantial opportunities for businesses involved in the medical equipment and biomanufacturing sectors, particularly those specialising in advanced bioprocessing technology. Companies with expertise in alternating tangential flow technology and integration within GMP environments would find this contract appealing because the technology chosen is preferred for its technical superiority and broader industry acceptance. As the process focuses on enhancing bio-therapeutic manufacturing operations, businesses that can provide compatible single-use systems or complementary services might significantly benefit from future collaboration or demand driven by similar projects.

## Notice

CGTC Braintree plan to purchase Non-GMP Alternating Tangible Flow (ATF) equipment in August 2026 to support the development of the process that will be transferred to GMP Manufacturing.

### Procurement Information

This purchase is for a lab base non-GMP system, but it is required to support the development of the process that will be transferred to GMP Manufacturing as part of the Ena Biologics BMIC Project (Ena Project). A Repligen system will be used in GMP Manufacturing in connection with the Ena Project for the reasons listed below, and therefore the corresponding smaller scale lab system is required for this purchase. Repligen are the only supplier of GMP [HS1.1][PD1.2][HS1.3][PD1.4]Perfusion equipment that operates using Alternating Tangential Flow. There is no other commercially available system that can perform single-use ATF style perfusion suitable for use in a GMP cleanroom. ATF style perfusion has been selected for this Project as it is technically superior to the alternative TFF (Tangential Flow Filtration)-based or acoustic-based perfusion devices and there is wider industry adoption of ATF for use in bio-therapeutic manufacturing operations for this reason. Alternative suppliers found from online searches have single-use TFF systems available such as the Sartorius Sartoflow 5000 SU TFF System, but these are not suitable for use in perfusion applications and are not proven to readily connect with Thermo Fisher Dynadrive bioreactors. Extensive re-engineering of BMIC existing systems would need to take place in order to interface these devices and even then it is unlikely to achieve the process intensity outputs required for the Ena Project to achieve a suitable reduction in cost of goods.
