nivolumab

Nivolumab is a monoclonal antibody and is a humanized PD-1 antibody. Nivolumab has anti-tumor activity and is used in the treatment of melanoma, non-small cell lung cancer, renal cell carcinoma, etc.

TMP1 is an orally active dual inhibitor targeting M pro (IC50= 312.5 nM) and TMPRSS2 (IC50= 1.28 μM, KD= 10.10 μM). It shows broad-spectrum protective effects in vitro against various SARS-CoV-2 variants. In vivo, TMP1 provides cross-protection against highly pathogenic coronaviruses, including SARS-CoV-1, SARS-CoV-2, and MERS-CoV, and effectively blocks the transmission of SARS-CoV-2. Additionally, TMP1 can inhibit the infection of SARS-CoV-2 escape mutants resistant to Nivolumab. TMP1 is useful in coronavirus research.

Cabiralizumab (FPA 008) is an anti-CSF1R monoclonal antibody (mAb) that enhances T cell infiltration and strengthens antitumor immune responses. Cabiralizumab prevents osteoclast activation, thereby inhibiting bone destruction, and is employed in rheumatoid arthritis (RA) research. Additionally, Cabiralizumab has been investigated in combination with Nivolumab in lung cancer studies, highlighting its role in immune-oncology.

Visugromab (CTL-002) is a monoclonal antibody that targets and neutralises GDF-15. Visugromab exhibits synergistic anticancer activity with the anti-PD1 antibody Nivolumab, making it suitable for PD-1/PD-L1 recurrent/refractory metastatic solid tumours.

Etigilimab represents a highly specialized humanized IgG1 monoclonal antibody specifically engineered to target the T-cell immunoreceptor with Ig and ITIM domains (TIGIT) with exceptional binding affinity and selectivity. It effectively facilitates the measurable blockade of the TIGIT/CD155 (PVR) inhibitory axis across various preclinical experimental models to evaluate the restoration of T-cell and NK-cell effector functions during strictly monitored laboratory observation periods and functional immune activation assays to ensure high experimental sensitivity.

ML-T7, a powerful inhibitor of Tim-3, effectively disrupts its interactions with PtdSer and CEACAM1. This compound enhances the antitumor activity of adoptive transfer therapy involving cytotoxic T lymphocytes (CTLs) and CAR T cells, while also boosting T cell effector functions. Additionally, ML-T7 augments the killing activity of NK cells against tumor cells and improves the antigen-presenting capacity of dendritic cells (DCs). Demonstrating antitumor efficacy in preclinical models, ML-T7 shows potential either as a standalone treatment or in combination with Nivolumab for tumor immunotherapy research [1].
