Fatty acid amide hydrolase inhibition for treatment of amyotrophic lateral sclerosis. (PubMed, JCI Insight) - "Experiments with ALS cellular models, iPS cells derived from ALS patients and SOD1G93A transgenic mice revealed that PF-04457845, a fatty acid amide hydrolase inhibitor, upregulated the expanded ECS, particularly the levels of NATs and ameliorated motor neuron degeneration through the regulation of microglial environment, synapse plasticity, and neuronal development. These results collectively indicate that dysregulation of NATs is associated with ALS progression and PF-04457845 may represent a potential disease-modifying therapy for ALS."

Enhancing anandamide signalling through fatty acid amide hydrolase inhibition: An update on the pharmacological strategy for treating psychiatric disorders. (PubMed, Transl Psychiatry) - "Presently, only two compounds, PF-04457845 (JZP150) and JNJ-42165279, have progressed to Phase II trials, demonstrating modest clinical benefit in CUD, with no efficacy in PTSD or osteoarthritis pain. Herein, we discuss emerging insights, safety considerations, broader mechanistic implications, and future directions for FAAH-targeted therapeutics, advocating for a precision medicine approach to realise their potential in the treatment of psychiatric disorders."

CHRONIC FAAH INHIBITION MODULATES SEX-DEPENDENT NEUROINFLAMMATORY RESPONSES IN THE 5XFAD MOUSE MODEL OF ALZHEIMER'S DISEASE (ADPD 2026) - "We aimed to investigate the impact of chronic FAAH inhibition on neuroinflammation and glial activity in a transgenic model of Alzheimer's disease (AD), with a focus on sex-dependent effects. Six-month-old male and female 5xFAD mice received the irreversible FAAH inhibitor PF-04457845 (10 mg/kg) orally for three months... Our findings highlight significant sex differences in neuroinflammatory processes in the 5xFAD model of AD. FAAH inhibition exerted a protective effect in females by dampening neuroinflammation and supporting neuronal integrity. These results reinforce the role of the ECS as an endogenous protective system and point to FAAH as a promising therapeutic target for AD, warranting further exploration of sex-specific mechanisms."

Pharmacotherapies for cannabis use disorder. (PubMed, Cochrane Database Syst Rev) - "There is incomplete evidence for all the clinically-important pharmacotherapies investigated and, for half of their outcomes, the quality of the evidence was low (44%) or very low (11%). Given the limited evidence of efficacy, those pharmacotherapies should still be considered experimental for treating cannabis use disorder. The greater withdrawal from treatment due to adverse effects seen with anticonvulsants and mood stabilisers may limit their therapeutic value."

Endocannabinoid contributions to the perception of socially relevant, affective touch in humans. (PubMed, Neuropsychopharmacology) - "In study 2, healthy individuals were randomized to receive an inhibitor of fatty acid amide hydrolase (FAAH; PF-04457845) to increase AEA levels (n = 16) or placebo (n = 29)...In contrast to our hypothesis, elevated AEA was associated with reduced pleasantness ratings of CT-optimal, affective touch. This provides novel, in-human data linking AEA to social processing, adding nuance to the rationale for its use as a potential novel therapeutic target in disordered in social processing."

A Neuroanatomic and Pathophysiologic Framework for Novel Pharmacological Approaches to the Treatment of Post-traumatic Stress Disorder. (PubMed, Drugs) - "Indeed, investigations and drug development are proceeding in a number of these alternative, non-serotonergic pathways in an effort to improve the management of PTSD. In this manuscript, the authors introduce novel and emerging treatments for PTSD, including drugs in various stages of development and clinical testing (BI 1358894, BNC-210, PRAX-114, JZP-150, LU AG06466, NYV-783, PH-94B, SRX246, TNX-102), established agents and known compounds being investigated for their utility in PTSD (brexpiprazole, cannabidiol, doxasoin, ganaxolone, intranasal neuropeptide Y, intranasal oxytocin, tianeptine oxalate, verucerfont), and emerging psychedelic interventions (ketamine, MDMA-assisted psychotherapy, psilocybin-assisted psychotherapy), with an aim to examine and integrate these agents into the underlying pathophysiological frameworks of trauma-related disorders."

Dual fatty acid hydrolase and TRPV1 inhibitor reduces inflammation and post-traumatic headache like symptoms induced by repetitive traumatic brain injury (Neuroscience 2023) - "Mice (n=6/group) were randomly assigned to treatment with either dual FAAH/TRPV1 inhibitor N-arachidonoyl-serotonin (AA-5-HT) or FAAH inhibitor PF-04457845 or vehicle...06). The results from this study suggest that reversal of TBI induced inflammation in the trigeminal regions and PTH-like symptoms by AA-5-HT is likely in part through augmentation of endocannabinoid (anandamide) and desensitization of TRPV1 neurons involved in nociception."

Modulation of TRPV1 activity by endocannabinoid anandamide in the development and treatment of posttraumatic headache (Neuroscience 2023) - "Unexpectedly, treatment with the FAAH inhibitor PF04457845 did not attenuate inflammation in the trigeminal system and had little effects on periorbital allodynia...These results suggest that TRPV1 signaling mediated by AEA is likely exaggerated by deletion of FAAH, and blockade of the TRPV1 activity can boost the pain suppressive effects of AEA in the FAAH KO mice. We are currently under investigation if the therapeutic effect of SB-366791 in the FAAH KO mice is also attributed to activation of cannabinoid receptors."

Therapeutic Effects of Combined Treatment with the AEA Hydrolysis Inhibitor PF04457845 and the Substrate Selective COX-2 Inhibitor LM4131 in the Mouse Model of Neuropathic Pain. (PubMed, Cells) - "Consistently, the increased proinflammatory cytokines IL-1β, IL-6, and chemokine MCP-1 in the CCI mouse spinal cord and sciatic nerve were also significantly reduced by combination of low doses of PF04457845 and LM4131 treatment. Therefore, our study suggests that simultaneous blockage of endocannabinoid hydrolysis and oxygenation by using the substrate-selective COX-2 inhibitor, which avoids the cardiovascular and gastrointestinal side effects associated with the use of general COX-2 inhibitors, might be a suitable strategy for the treatment of inflammatory and neuropathic pain."

Inhibition of FAAH suppresses RANKL-induced osteoclastogenesis and attenuates ovariectomy-induced bone loss partially through repressing the IL17 pathway. (PubMed, FASEB J) - "Moreover, intragastric administration of the FAAH inhibitor PF-04457845(PF) ameliorated ovariectomy (OVX)-induced bone loss in mice...RNAseq indicated that the IL17 pathway was blocked by PF, and administration of recombinant murine IL17 protein could partially restore osteoclastogenesis and activate NF-κB and MAPK pathways. To sum up, our findings demonstrate that targeting FAAH could be a promising candidate strategy for treating osteoclast-related diseases, especially osteoporosis."

Endocannabinoid Contributions to Affective Touch Processing in Humans With or Without Trauma Exposure Histories (ACNP 2022) - "In study 2, we further demonstrated the role for AEA in affective touch processing by using PF-04457845 (now known as JZP150) to enhance AEA levels via reduced enzymatic degradation in healthy adults... Overall, we find that increases in the stress-buffering endocannabinoid ligand AEA may play a critical role in mediating the perceived pleasantness of affective touch, as evidence both by individual variation in AEA levels and pharmacological intervention. This data suggests that when AEA is high, the impact of the stress buffering qualities of affective, CT-optimal touch may be minimal. As such, it is possible that individuals with lower AEA, or states that induce decreases in AEA (i.e., following stress exposure), may be particularly responsive to the stress buffering qualities of socially relevant, affective touch, providing insight into populations who may most benefit from social support via affective touch."
