Lpa-induced activation of satellite glia cells and its modulation by pipe-791, a novel lpa1 antagonist, in an in vitro pain model (Neuroscience 2025) - "Notably, PIPE-791 significantly reduced the expression of GFAP and FABP7, reinforcing the role of LPA signaling in neuropathic pain and demonstrating that LPA₁ antagonism can effectively attenuate glial activation. Collectively, these findings suggest that PIPE-791 may alleviate pain in vivo by modulating LPA-induced activation of satellite glial cells (SGCs)."

Cns-penetrant lpa₁ antagonist pipe-791 provides superior analgesia compared to peripherally restricted ctx-343 in a rat model of lpa-induced osteoarthritis (Neuroscience 2025) - "Of note, neuropathic pain can be ameliorated by CNS administration of either an anti-IL-6 antibody or an autotaxin inhibitor. As such, PIPE-791's superior analgesic profile highlights the importance of targeting central LPA₁ signaling and supports further development of CNS-penetrant LPA1 antagonists for OA and neuropathic pain."

The LPAR1 antagonist, PIPE-791 produces antifibrotic effects in models of lung fibrosis. (PubMed, Respir Res) - "We show that PIPE-791 effectively reduces fibrosis and fibrotic markers in vitro and in vivo and that it has slow association and dissociation kinetics. Taken together, our data support clinical testing of PIPE-791 in the context of fibrotic conditions such as IPF."

Reduced activation of pain-related brain regions with lysophosphatidic acid receptor subtype-1 antagonist PIPE-791 in a nonhuman primate model of chronic peripheral neuropathy. (PubMed, Neuropharmacology) - "Evoked brain activation could be related to painful peripheral neuropathy and reduced brain activation could be a direct indicator of reduced pain perception following treatment. The current findings suggest decreasing neuroinflammation by blocking LPA1Rs could be a novel approach to the management chronic painful peripheral neuropathy."

Lysophosphatidic Acid Receptor Subtype-1 Antagonist PIPE-791 Reduces Neuropathic Pain in Macaques (IASP 2024) - "Based on suppression of brain regions mediating pain intensity and pain affect in a nonhuman primate model of peripheral neuropathy, the current neuroimaging findings support the notion that LPAR1 block leads to antinociception. The current findings also suggest blocking neuroinflammation as a novel mechanism of reducing neuropathic pain. Further studies are needed to assess whether suppression of peripheral or central LPAR1 is crucial for antinociceptive efficacy."
