NXC736

NXC736 is a novel small-molecule compound that targets Sphingosine-1 Phosphate (S1P) receptors, reducing lymphocyte migration from peripheral circulation to inflamed tissues, thereby exerting an immunosuppressive effect.

Unlike existing therapies that act non-selectively on S1P receptors, NXC736 selectively targets S1PR1 and S1PR4, leading to improved safety and reduced side effects.

In 2020, NXC736 was selected for the Advanced Medical Technology Development Program by the Korea Health Industry Development Institute (KHIDI) and successfully completed Phase 1 clinical trials. In 2024, it was chosen as a Phase 2 clinical trial project by the Korea Drug Development Fund (KDDF) and is currently in Phase 2 clinical trials.

Indication Alopecia Areata, Ulcerative Colitis
Route of Administration Oral
Development Status Phase II
Mechanism of Action S1P Receptor 1&4 Selective Modulator
Highlight
  • Highly selective S1P receptor 1 & 4 modulator
  • Low opportunistic infections via quick lymphocyte reduction and recovery
  • Safe profile that does not cause bradycardia
  • Excellent efficacy compared to competing drugs in autoimmune disease models such as alopecia areata and ulcerative colitis due to T-lymphocyte-mediated immunosuppressive effect
  • Fast lymphocyte suppression & recovery observed without significant AEs in Phase I study
  • Phase II in progress
