Regarding breast cancer, I see there are over 100

Regarding breast cancer, I see there are over 100 different types. I only read about us doing studies for TNBC, but since these comprise only 10 - 20% of breast cancer -

Is TNBC the only type of breast cancer that needs/uses the CCR5 receptor?

If not, are there other types of breast cancer that could be stopped with Leronlimab?

And if so, do we know what percent of the overall breast cancer population LL could attack?

Thanks!
