Anti-GARP: Combatting Treg Cells and TGF-β in the Tumor Microenvironment

AbbVie has recently licensed rights to a monoclonal antibody discovered by Argenx, ARGX-115, paying $20MM up-front and up to $625MM in milestones based on development, approval, and commercial performance. This monoclonal antibody targets a central player in the complex tumor microenvironment – the regulatory T-cell (Treg). Continue reading

Turning “cold tumors hot” – rationale, major setback, and promise

One of the most active fields of clinical investigation in immuno-oncology today is augmenting responses to checkpoint [CTLA4 or PD-(L)1] inhibition therapy by re-sensitizing tumors that were initially unresponsive or had stopped responding to treatment. Continue reading

Mutational burden biomarker – not just mismatch repair deficiency

We have discussed mutational burden previously on this blog – in essence, the concept is that tumors with more mutations are more visible to the immune system because the generation of new novel antigenic epitopes allows for adaptive immune responses even when previous adaptive antigen-specific immune responses have been blunted by PD-1 expression. Continue reading
