so how long would it take to bring leronlimab to the forefront as a primary treatment vs only to be used as a plan C and only after other drugs have failed? i keep forgetting that this is how leronlimab might get approved for HIV, a backup plan...what other drugs are cornered and restricted like this? i have never heard of this...wont leronlimab prove to be as effective or better than other current drugs but the safety profile makes it exceptional and preferred?
