Definitions

  • Pain is a protective mechanism that allows healthy animals to avoid tissue damage and to prevent further damage to injured tissue. Managing pain in the clinical setting, in both acute and chronic clinical settings, remain a high unmet need. In addition to acute pain, there are many conditions where chronic pain persists beyond its protective role (neuropathic pain) where patients would benefit from inhibition of pain.
  • Neuropathic pain is a form of chronic pain caused by an injury to the sensory nerves (Dieleman, J. P., et al., Incidence rates and treatment of neuropathic pain conditions in the general population. Pain, 2008. 137(3): p. 681-8). Neuropathic pain can be divided into two categories, pain caused by generalized metabolic damage to the nerve and pain caused by a discrete nerve injury.
  • the metabolic neuropathies include post herpetic neuropathy, diabetic neuropathy, and drug-induced neuropathy.
  • Discrete nerve injuries indications include post amputation pain, post-surgical nerve injury pain, and nerve entrapment injuries like neuropathic back pain.
  • AEs adverse events
  • lidocaine a nonselective sodium channel blocker
  • Opioid pain medications have a high abuse liability, leading to frequent deaths due to overdose.
  • opioid-induced hyperalgesia also limits the long term use of opioids.
  • Opioid-induced hyperalgesia is encountered regularly in clinical practice and creates significant challenges in pain management. The limited treatment options for pain, combined with a growing awareness of the risks of the current standards of care, underscore the need for new pain management therapies.
  • Na v 's Voltage-gated sodium channels
  • Na v 's are biological mediators of electrical signaling as they mediate the rapid upstroke of the action potential of many excitable cell types (e.g. neurons, skeletal myocytes, cardiac myocytes).
  • excitable cell types e.g. neurons, skeletal myocytes, cardiac myocytes.
  • the evidence for the role of these channels in normal physiology, the pathological states arising from mutations in sodium channel genes, preclinical work in animal models, and the clinical pharmacology of known sodium channel modulating agents all point to the central role of Na v 's in pain sensation (Rush, A. M. and T. R.
  • the Na v 's form a subfamily of the voltage-gated ion channel super-family and comprises 9 isoforms, designated Na v 1.1-Na v 1.9.
  • the tissue localizations of the nine isoforms vary.
  • Na v 1.4 is the primary sodium channel of skeletal muscle
  • Na v 1.5 is primary sodium channel of cardiac myocytes.
  • Na v 's 1.7, 1.8 and 1.9 are primarily localized to the peripheral nervous system, while Na v 's 1.1, 1.2, 1.3, and 1.6 are neuronal channels found in both the central and peripheral nervous systems.
  • the functional behaviors of the nine isoforms are similar but distinct in the specifics of their voltage-dependent and kinetic behavior (Catterall, W. A., Goldin, A. L., and Waxman, S. G., International Union of Pharmacology. XLVII. Nomenclature and structure-function relationships of voltage-gated sodium channels. Pharmacol. Rev. 57 (4),
  • Na v 1.8 channels were identified as likely targets for analgesia (Akopian, A. N., L. Sivilotti, and J. N. Wood, A tetrodotoxin-resistant voltage-gated sodium channel expressed by sensory neurons. Nature, 1996. 379(6562): p. 257-62). Since then, Na v 1.8 has been shown to be a carrier of the sodium current that maintains action potential firing in small DRG neurons, supporting its potential as a target for multiple indications or across multiple pain types (Blair, N. T. and B. P.
  • Na v 1.8 is involved in spontaneous firing in damaged neurons, like those that drive neuropathic pain (Roza, C., et al., The tetrodotoxin-resistant Na + channel Na v 1.8 is essential for the expression of spontaneous activity in damaged sensory axons of mice. J. Physiol., 2003. 550(Pt 3): p. 921-6; Jarvis, M.
  • the small DRG neurons where Na v 1.8 is expressed include the nociceptors involved in pain signaling.
  • Na v 1.8 mediates large amplitude action potentials in small neurons of the dorsal root ganglia (Blair, N. T. and B. P. Bean, Roles of tetrodotoxin (TTX)-sensitive Na + current, TTX-resistant Na + current, and Ca 2+ current in the action potentials of nociceptive sensory neurons. J. Neurosci., 2002. 22(23): p. 10277-90).
  • Na v 1.8 is necessary for rapid repetitive action potentials in nociceptors, and for spontaneous activity of damaged neurons. (Choi, J.
  • Na v 1.8 appears to be a driver of hyper-excitablility (Rush, A. M., et al., A single sodium channel mutation produces hyper- or hypoexcitability in different types of neurons. Proc. Natl. Acad. Sci. USA, 2006. 103(21): p. 8245-50).
  • Na v 1.8 mRNA expression levels have been shown to increase in the DRG (Sun, W., et al., Reduced conduction failure of the main axon of polymodal nociceptive C-fibers contributes to painful diabetic neuropathy in rats. Brain, 135( Pt 2) : p. 359-75; Strickland, I.

  • Investigational Arm 4 Compound 1 will be administered every 12 hours (q12 h) in a dose of 500 mg. The final dose of Compound 1 will be given 36 hours after the first dose.
  • Subjects will report their pain on the 11-point NPRS immediately before their first dose of the study drug (baseline NPRS score) and throughout the study after the first dose of study drug.
  • the primary endpoint will be the time-weighted sum of the pain intensity difference between Compound 1 versus placebo as recorded on a Numeric Pain Rating Scale (NPRS) 0 to 48 hours (SPID48) after the first dose.
  • NPRS Numeric Pain Rating Scale
  • SPID48 0 to 48 hours
  • pairwise comparison in SPID48 between Compound 1 and placebo will be further conducted using an analysis of covariance (ANCOVA) model.
  • a secondary endpoint will be the time-weighted sum of the pain intensity difference between each dose level of Compound 1 versus placebo as recorded on a NPRS 0 to 24 hours (SPID24) after the first dose.
  • a secondary endpoint will be the proportions of subjects with at least 30%, 50%, or 70% reductions in NPRS at 24 hours after the first dose of Compound 1 versus placebo.
  • a secondary endpoint will be the plasma PK parameters of 2-(4-fluoro-2-methylphenoxy)-N-(2-oxo-1,2-dihydropyridin-4-yl)-4-(trifluoromethyl)benzamide, the parent compound of Compound 1.
  • Compound 1 was administered orally in 250 mg capsules, prepared as described in Example 2.
  • subjects reported their average pain and sleep interference to establish a baseline NRS pain score and DSIS score.
  • Compound 1 was administered to the subjects in the Treatment Arm every 24 hours (q24 h) in a dose of 1250 mg.
  • Subjects in the Placebo Arm received placebo capsules.
  • Pain intensity was evaluated using an 11-point NRS.
  • the 11-point scale ranged from 0 (no pain) to 10 (worst imaginable pain). From Day ⁇ 7 through Week 6, subjects reported their average daily pain during the last 24 hours on the NRS via electronic diary.
  • DSIS Daily Sleep Interference Scale
  • Subjects reported pain interference with sleep using an 11-point scale ranging from 0 (none) to 10 (severe). The DSIS score was reported each morning in an electronic diary.
  • NRS pain scores were averaged over weekly periods to reduce the impact on the analyses of individual high or low pain scores.
  • the mean change from baseline in the weekly average of daily pain intensity on the 11-point NRS over the course of the treatment period for subjects in the Placebo and Treatment Arms is depicted graphically in FIG. 3 .
  • the mean change at Week 6 is reported in Table 7.
  • the mean change from baseline for those treated with Compound 1 compared to placebo was ⁇ 1.09 (95% CI: ⁇ 1.88 to ⁇ 0.29) at Week 6.
  • a treatment difference of greater than 1 point was observed as early as Week 1, demonstrating pain relief as early as the first week of treatment that was sustained through the six-week treatment period.
  • the number and percentage of subjects with ⁇ 30% and ⁇ 50% reduction in the weekly average of daily pain intensity on the 11-point NRS at Week 6 is reported in Table 9. The total number of subjects for determining the percentage was based on subjects who had data at Week 6.
