Clone 3 is a mAb, so they usually just discuss them as a category of therapeutics IMO:
"The Company has also pioneered a proprietary method for creating human cell lines that produce fully human monoclonal antibodies directed against many infectious diseases. One antibody (designated as CLONE 3) has been demonstrated in tests in 5 international labs to fully neutralize over 95% of all strains and viral subtypes of HIV-1 against which it has been tested."
