The combination of OPDIVIO and YERVOY seems to be the leading treatment. It looks like Sutent was the previous standard of care.

So what's the opportunity for Bisantrene:

1. OPDIVIO is a PD-1 inhibitor
2. PD-1 inhibitors are susceptible to resistance

3. Inhibiting FTO can make PD-1 inhibitors work better (that's been shown for Melanoma)
   https://www.nature.com/articles/s41467-019-10669-0
4. 90% of ccRCC are caused by mutations in the von Hippel-Lindau (VHL) tumour suppressor gene

5. FTO was found to be synthetically lethal in cells with inactive VHL. Inhibition of FTO was found to kill VHL(-) ccRCC cancers.

I can see a head to head battle between BMS and Merck and potentially a keen interest in what Bisantrene could do to make their PD-1 inhibitors work better.
