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

Pharmaceutical Technology

The most widely utilised IO class is immune checkpoint inhibitors (ICIs), which work by blocking the inhibitory interactions between tumour cells and T-cells, facilitating an anti-tumour immune response. There are more than 20 marketed ICIs with approvals across a very wide spectrum of solid tumour indications.

The patient then receives chemotherapy to reduce regulatory T cells that can put a brake on immune responses to tumours, as well as immune-boosting cytokine interleukin-2, before the TILs are then reinfused into the patient intravenously.

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.

COVID prompts another milestone, as India clears first DNA vaccine

pharmaphorum

DNA vaccines work by delivering a genetically-engineered plasmid containing the DNA sequence encoding the desired antigen – in this case the SARS-CoV-2 spike protein – which is then taken up by cells. Proponents of the approach claim that DNA vaccines may have advantages over other technologies like mRNA.
