Trials and Approvals 

Shanghai Zai Lab (NSDQ: ZLAB; HKEX: 9688) and Boston's Entasis Therapeutics (NSDQ: ETTX) have completed enrollment in a global Phase III trial of novel combination antibacterial (see story). Entasis' SUL-DUR combines two IV antibacterial aimed at treating infections caused by Acinetobacter baumannii, including carbapenem-resistant strains.

Suzhou Innovent Bio (HK: 01801) started a China Phase I trial of an anti-PD-1/TIGIT bispecific antibody in advanced malignant tumors, especially GI cancers (see story). Innovent said preclinical studies of IBI321 showed it retains the activity of a PD-1 inhibitor while suppressing TIGIT to enhance anti-cancer efficacy. TIGIT is an immune checkpoint receptor that plays a role in tumor immune surveillance. IBI321 was discovered through a collaboration between Innovent and Eli Lilly, but is being developed in China by Innovent. The Phase Ia study will evaluate dosing of IBI321 in several solid tumors.  

Shanghai's I-Mab  (NSDQ: IMAB) has been cleared to start a US Phase I trial of its novel immunotherapy for Alzheimer's (see story). Protollin is composed of outer membrane bacteria proteins complexed with lipopolysaccharides that is delivered nasally to cross the brain-blood barrier. It is aimed at stimulating an immune response against the build-up of beta amyloid protein plaques and subsequent tau tangles. I-Mab will develop protollin ex-China; Nhwa owns China rights. The two China biopharmas in-licensed global rights to the candidate from Boston's Brigham and Women's Hospital and Inspirevax, a Montreal biotech.
