Graphic Inbrx 106

the Candidate

Our hexavalent OX40 agonist.

Hexavalent engagement of OX40 is designed to:

  • Engage multiple OX40 receptors and promote hyperclustering.
  • Enhance activation of the OX40 costimulatory pathway without the need for Fc crosslinking.
  • Promote proliferation of activated T-cells.
  • Enhance T-cell functionality.
  • Induce reversal of regulatory T-cell–mediated immune suppression.

Going Beyond the Bivalent Approach

We believe that INBRX-106 can outperform bivalent agonists and has the potential to be widely used in combination with approved checkpoint inhibitors and also effective in tumors non-responsive to approved checkpoint inhibitors.

INBRX-106 Clinical Trials

HexAgon-HN Logo

The global, randomized, phase 2/3 study (NCT06295731) is evaluating INBRX-106 + pembrolizumab vs pembrolizumab alone as first-line therapy for patients with treatment-naive HNSCC and high PD-L1 expression (combined positive score [CPS] of ≥20).

Phase 2/3 Trial

The ongoing phase 1/2 study (NCT04198766) is evaluating INBRX-106 in combination with pembrolizumab in various solid tumors including NSCLC and HNSCC.
