Abstract
(EN) This invention provides a bispecific antibody that (i) specifically binds to the extracellular portion of human angiotensin converting enzyme 2 (hACE2); (ii) specifically binds to the extracellular portion of human TMPRSS2 (hTMPRSS2); (iii) does not significantly inhibit the ability of hACE2 to cleave angiotensin II and/or a synthetic MCA-based peptide; and (iv) specifically inhibits the entry into hACE2+/hTMPRSS2+ human cells of a pseudovirus bearing SARS-CoV-2 S protein. This invention also provides related pharmaceutical compositions, recombinant nucleic acid molecules, vectors, AAV particles, therapeutic and prophylactic methods, and kits.
(FR) La présente invention concerne un anticorps bispécifique qui (i) se lie spécifiquement à la partie extracellulaire de l'enzyme de conversion de l'angiotensine humaine 2 (hACE2); (ii) se lie spécifiquement à la partie extracellulaire de TMPRSS2 humain (hTMPRSS2); (iii) n'inhibe pas significativement la capacité de hACE2 à cliver l'angiotensine II et/ou un peptide à base de MCA synthétique; et (iv) inhibe spécifiquement l'entrée dans les cellules humaines hACE2+/hTMPRSS2+ d'un pseudovirus portant la protéine S du SARS-CoV-2. L'invention concerne en outre des compositions pharmaceutiques, des molécules d'acide nucléique recombinantes, des vecteurs, des particules d'AAV, des procédés thérapeutiques et prophylactiques et des kits associés.
