About this program

Lirilumab (IPH2102/BMS-986015) is a fully human monoclonal antibody that is designed to block the interaction between KIR2DL-1,-2,-3 inhibitory receptors and their ligands.

Blocking these receptors facilitates activation of NK cells and, potentially some subsets of T cells, ultimately leading to destruction of tumor cells.

Lirilumab, an anti-KIR monoclonal antibody, aims at “unblinding” NK cells and facilitating their activation by blocking their inhibitory receptors.  

Lirilumab and related compounds blocking KIR receptors are licensed to Bristol-Myers Squibb Company (NYSE:BMY), for all indications.

Lirilumab has been or is currently being tested in several indications and combination settings.

Lirilumab continues to be well tolerated in monotherapy and in combination across multiple tumor indications in an exploratory clinical program with partner Bristol-Myers Squibb.

The assessment of efficacy from the ongoing exploration of doublet combinations, notably the nivolumab combination in an extended population of SCCHN patients, did not provide clear evidence of benefit to patients or an obvious development path.

Separately, full data of the EffiKIR Phase II study presented at ASH 2017 suggests that alternate dosing regimens could be worth exploring.

Discussions with Bristol-Myers Squibb regarding next steps are ongoing.
