Using bispecific antibodies to advance cancer immunotherapy

pharmaphorum

Dr Laura Moriarty, senior marketing manager at Bio-Rad, looks at the impressive immuno-therapeutic potential of bispecific antibodies (bsAbs). Though their bispecific nature complicates large-scale production and purification workflows, with challenges such as antibody chain mispairing, bsAbs have come a long way since first developed.

A broad range of unmet needs remains in the immuno-oncology space

Pharmaceutical Technology

IO agents include the classes of immune checkpoint modulators, cell therapies, bispecific antibodies, oncolytic viruses, therapeutic vaccines, and cytokines. All currently approved CAR-Ts are autologous, with the patient’s T-cells being genetically engineered to target antigens expressed by the cancerous cells.

Novavax Announces Agreement with Government of New Zealand for 10.7 Million Doses of COVID-19 VaccineAdvance purchase agreement signed for NVX-CoV2373, Novavax’ adjuvanted protein vaccine candidate

The Pharma Data

Currently in Phase 3 clinical testing in the United Kingdom for the prevention of COVID-19, NVX-CoV2373 is a recombinant protein vaccine adjuvanted with Novavax’ proprietary Matrix-M to enhance the immune response. NVX-CoV2373 contains purified protein antigen and can neither replicate, nor can it cause COVID-19. and Australia.

Taconic Biosciences Expands Immuno-oncology Animal Model PortfolioCritical Jh Syngeneic Tumor Model Host Now Available on a B6 Background

The Pharma Data

These models are engrafted with mouse tumors derived from the same strain background; this genetic similarity between tumor and host prevents the host from rejecting the tumor. One consideration in using syngeneic models is that some drug candidates can cause a negative immune response not seen in humans.
