I tried with 17: https://pmc.ncbi.nlm.nih.gov/articles/PMC7925581/
From figure 1:
> Complete tumor regression was observed in 6/15 mice on the combination treatment, 1/20 on ivermectin alone, 1/10 on anti-PD1 antibody alone, and 0/25 on no treatment.
Ok, that looks interesting.
Right? I learned too.
As I mentioned above (another comment), pharma tends to avoid developing applications for generic/cheap drugs so we may not see more research on this front. Who knows.
