$MDNAF PD-1 refactory (i.e no response to PD-1 drugs like Keytruda, Nivo) are the hardest tumor to treat in Oncology. Since 2018, You cannot ethically or legally start a new immunotherapy trial in an easy population (PD-1 Naïve) where PD 1 already works. So MDNA11 didn’t start in the hardest tumors by choice — it started there because modern immunotherapy trials require it.
Other IL‑2s with mega billion$ deals (Nektar, Synthrox, Alkermes, Xilio, etc) started in the same place, failed, and quickly retreated to easier tumors — and still failed.
MDNA11 is the first IL‑2 showing real activity in PD‑1–refractory disease, proving that when the biology is solid, a drug can win in the toughest cancers first.
If a drug works in PD 1–refractory tumors, it’s almost guaranteed to work in easier tumors. So, starting in the hardest setting is actually: A stress test. If the drug passes, it’s a monster.
MDNA11 is passing! - The upcoming oral presentation shows the science is holding up very well
