Pipeline
Through in-house discovery and strategic in-licensing with global best-in-class partners, we are accelerating the development and delivery of breakthrough medicines to patients around the world.
Brii Bio is building a pipeline of more than 10 novel therapeutic candidates that allows the Company to develop differentiated treatment options for patients based on two key methods:

- Based on a licensing agreement with VBI Vaccines, Brii Bio has the exclusive rights to develop and commercialize BRII-179 in Greater China.

BRII-877 (VIR-3434)(1)
BRII-877 (VIR-3434)
- Phase 2 development in China.
- BRII-877 is an investigational subcutaneously administered HBV-neutralizing monoclonal antibody designed to block entry of all 10 genotypes of HBV into hepatocytes and to reduce the level of virions and subviral particles in the blood.
- Based on a licensing agreement with Vir Biotechnology, Brii Bio has the exclusive rights to develop and commercialize BRII-877 in Greater China.

Amubarvimab/Romlusevimab Combination
Amubarvimab/Romlusevimab Combination
- Approved by the NMPA and commercially available in China.
- Amubarvimab and romlusevimab are non-competing SARS-CoV-2 monoclonal neutralizing antibodies derived from convalesced COVID-19 patients developed in collaboration with the 3rd People’s Hospital of Shenzhen and Tsinghua University. They have been specifically engineered to reduce the risk of antibody-dependent enhancement and prolong the plasma half-lives for a potentially more durable treatment effect. Live virus testing data, as well as pseudovirus testing data from multiple independent labs, have demonstrated that the amubarvimab / romlusevimab combination retains neutralizing activity against all major SARS-CoV-2 variants of concern.

BRII-732
BRII-732
- Phase 1 development in the U.S.
- BRII-732 is a new chemical entity (NCE) that, upon oral administration, is a proprietary prodrug that is metabolized into the active moiety islatravir, an investigational candidate being studied to treat and prevent HIV infection. BRII-732 is being developed as part of a potential once-weekly, combination therapy with BRII-778 to treat HIV-1.
- Internally discovered.
BRII-672 (ORAvance)(2)
BRII-672 (ORAvance)
- Phase 1 development in China.
- BRII-672, a prodrug of BRII-636, is an oral beta-lactamase inhibitor in development for the treatment of multidrug- and extensively drug-resistant (MDR/XDR) Gram-negative bacterial infections.
- Based on a licensing agreement with Qpex Biopharma, Brii Bio has the exclusive rights to develop and commercialize BRII-672 in Greater China.

BRII-693 (QPX9003)(2)
BRII-693 (QPX9003)
- Phase 1 development in China.
- BRII-693 is a novel synthetic lipopeptide in development for the treatment of multidrug- and extensively drug-resistant (MDR/XDR) Gram-negative bacterial infections.
- Based on a licensing agreement with Qpex Biopharma, Brii Bio has the exclusive rights to develop and commercialize BRII-658 in Greater China.

BRII-636 (OMNIvance)(2)
BRII-636 (OMNIvance)
- Phase 1 development in China.
- BRII-636 is novel cyclic boronic acid derived broad-spectrum inhibitor in development for the treatment of multidrug- and extensively drug-resistant (MDR/XDR) Gram-negative bacterial infections.
- Based on a licensing agreement with Qpex Biopharma, Brii Bio has the exclusive rights to develop and commercialize BRII-636 in Greater China.

BRII-658 (Epetraborole)(3)
BRII-658
- Phase 1 development in China.
- BRII-658 is in development as a once-daily oral treatment for patients with chronic nontuberculous mycobacterial (NTM) lung disease, with an initial focus on treatment of refractory mycobacterium avium complex (MAC) lung disease.
- Based on a licensing agreement with AN2 Therapeutics, Brii Bio has the exclusive rights to develop and commercialize BRII-658 in Greater China.

BRII-296
PPD Treatment
- Phase 1 development in the U.S.
- BRII-296 is a novel, single injection therapeutic candidate in development for the treatment postpartum depression (PPD) . It acts as a gamma-aminobutyric acid A (GABAa) receptor positive allosteric modulator (PAM) and is designed to provide a rapid, profound and sustained reduction in depressive symptoms of PPD with the potential to lead to greater adherence, convenience and fewer side effects compared to the current standard of care.
- Internally discovered.
BRII-296
PPD Prevention
- Phase 1 development in the U.S.
