The G-Rex platform simplifies the transfer of the HG-CT-1 manufacturing process to Made Scientific (US) and Cellin Technologies (Estonia) by providing a highly reproducible environment. Unlike complex bioreactors that require stirring or perfusion, G-Rex uses a static environment that eliminates mechanical variables. Protocols developed at small scales correlate directly to larger clinical-scale devices, ensuring that the validated process at one site can be mirrored at others with identical results.
Using G-Rex reduces the technical barriers for third-party manufacturers, lowering the risk of human error during the transfer process. The "Fill and Forget" approach requires far fewer manual interventions than traditional methods, which is critical when outsourcing to a CDMO like Made Scientific.G-Rex utilises standard lab equipment (e.g., CO2 incubators), meaning partner sites do not need to invest in or learn to operate specialised, proprietary machinery. The $120,000 G-Rex grant HEMO were awarded was specifically intended to optimise a closed-system manufacturing platform to strengthen regulatory and CMC (Chemistry, Manufacturing, and Controls) strategies as required by the FDA. The G-Rex M-Series provides a functionally closed environment, helping Hemogenyx meet both the stringent FDA and European safety requirements for cell therapy production. The technology significantly lowers per-patient manufacturing costs—potentially to a $20,000 material cost standard—enhancing the commercial viability of commercial production in the states and the Estonian "Hospital Exemption" pathway.
Once this process is "locked," Hemogenyx intends to deploy the same validated G-Rex framework to Cellin Technologies in Estonia to initiate early-revenue patient treatments, with an unlimited number of patients to be treated. It should be noted that following the completion of the technology transfer to Made, Hemogenyx could deploy this process in any country or continent in the world that allows a form of exemption for a breakthrough therapy, and there are plenty that do.
Although not part of the US clinical protocol the recent changes to the FDA guidelines will allow both safety and efficacy data from around the world to be used in the fast tracking of approvals through various stages of the clinical trials, further reducing costs to Hemogenyx.
All investors need here is a little patience. In my opinion anyway.
