Perspectives
How does this study impact clinical practice?
- These preclinical findings demonstrates that orismilast is a potent inhibitor of PDE4 subtypes involved in inflammatory signalling cascades associated with chronic inflammatory diseases.
- Orismilast more selectively inhibited PDE4B and -4D subtypes, which are most relevant for inflammation.
- PDE4 inhibition was more potent than apremilast, the only approved oral PDE4 inhibitor in dermatology.
- Potent inhibition of the PDE4-B and -D subtypes may contribute to the improved efficacy of orismilast versus apremilast in inhibiting TNFα release.
- Phase 2 trials are underway in psoriasis, atopic dermatitis, and hidradenitis suppurativa.
