The company actually did a helpful video on this DR5 project.
https://investorhub.fusionantibodies.com/activity-updates/rkE32y-deep-dive-series-dr5
According to the video, they already have a working antibody and the 18-month programme (with Innovate UK funding alongside Queen’s University Belfast) is about getting it clinic-ready — humanised, manufacturable and validated in vivo.
What stood out to me in that vid is that apparently big pharma have been trying to crack DR5 for years (AstraZeneca, Genmab, Genentech all have programmes), but nothing has made it past Phase 2 and there are still no approved drugs.
According to the video, the issue is that DR5 only works if you activate three receptors together (trimerisation), and most antibodies haven’t been able to do that properly without complex engineering.
So others have had to use more complicated formats (IgM, hexamers, etc), which adds risk and hasn’t translated well clinically.
According to the video, Fusion’s antibody can trigger this naturally without extra cross-linking or complex formats, and when compared to failed antibodies it showed much stronger cell-killing activity.
If that holds up, it’s essentially addressing the main reason previous approaches struggled.
End goal here isn’t to run trials themselves — it’s to get to a clinic-ready asset and license it out.
So based on what they’ve said:
• Validated cancer target with major pharma interest
• Known technical challenge that’s held the field back
• Their antibody designed specifically to overcome that
If they can deliver what’s outlined in the video, you can see why this could be an attractive licensing opportunity.
