DMX-200 is included in the investigator-led feasibility/Phase 3 study in COVID-19 pneumonia patients, driven by global clinicians, experts, and trialists via the study sponsor, REMAP-CAP. The study is endorsed by the WHO and has commenced a master protocol across over 300 clinical trial sites across eight global regions.

Currently, REMAP-CAP investigates more than twenty active treatments for COVID-19, mostly repurposed and novel medicines, including registration purposes. Now, the study has recruited more than 6,000 patients with suspected or proven COVID-19 overall. Furthermore, the study is currently recruiting ~100 patients per week across Europe.

Two Phase 3 clinical trials for COVID-19

DMX-200, the lead drug candidate of Dimerix, is part of two different investigator-led Phase 3 clinical trials in COVID-19 patients with respiratory complications. For one of these studies, Dimerix was awarded AU$1 million from MTPConnect’s Biomedical Translation Bridge (BTB) program provided by the Australian Government’s Medical Research Future Fund (MRFF), with support from UniQuest.

Dimerix supports both the studies driven by the REMAP-CAP and CLARITY 2.0 teams in delivering them information for the regulatory submissions as well as in supplying DMX-200 to the study sites.

Interestingly, if DMX-200 shows benefit in COVID-19 patients, it could also benefit in respiratory complications associated with other infections, like pneumonia and influenza. Consequently, this provides an opportunity that could extend well beyond the COVID-19 impact.

On 23 April 2021, DXB shares last traded at AU$0.250, in line with the previous close.
