The Greatest Teacher, Failure is: False Positive and Negative Results in Analgesic Clinical Trials
This presentation will focus on efforts to improve clinical trial research methods as a means of accelerating the identification of analgesic medications with improved efficacy and safety. The major impetus for efforts to improve clinical trial methods has come from the observation that multiple recent clinical trials have failed to show efficacy of medications known to be efficacious. Several explanations for these negative results have been proposed, including (1) patients in the placebo groups improved “too much” to allow the analgesic medication to demonstrate its effect; (2) the optimal pain conditions or phenotypes were not studied; and (3) changes over the past two decades in the approaches used for conducting clinical trials and in the patients enrolled – including patient and investigator “misbehavior” and outright fraud -- have made false positive and negative results more likely. In ongoing research, methodologic factors and patient characteristics of analgesic clinical trials are being systematically examined so that possible sources of adverse effects on trial outcomes can be identified and then modified in future trials. On the basis of such research, recommendations will be presented for improving analgesic clinical trial assay sensitivity – that is, the ability of a clinical trial to show efficacy vs. placebo (or an active comparator) of a truly efficacious treatment.

Microglia – Their Role in Neuropathic Pain and Potential Therapeutic Targets
The microglia, acting as key elements of the immune system of the brain, have long been identified as critical in their role in maintaining CNS health. The last two decades have also advanced our understanding that they may also participate in various pathological processes in the CNS, including neuropathic pain. Learning objectives for this talk:
• Review of microglial activity in health and disease
• Discuss evidence of microglial activity in neuropathic pain
• Identify potential therapeutic targets based on our understanding of microglial activity

LEVI-04: A Novel and Safe Analgesic for the Treatment of Chronic Pain
From clinical studies, anti-NGF treatment has been reported to lead to profound analgesia. However, safety concerns, including rapid progression of osteoarthritis (OA) and transient parathesia have been reported. LEVI-04 is a novel biologic with unique pharmacology that safely modulates the neurotrophin pathway (NGF, NT-3, BDNF and NT-4) leading to analgesia and interestingly from pre-clinical models, evidence of disease modifying properties in OA. LEVI-04 is currently in clinical trials for treatment of chronic pain. This talk will cover the role of NGF in bone repair and maintenance, pre-clinical mechanisms of anti-NGF leading to rapid progression of OA, neurotoxicity of anti-NGF, mode of action, pre-clinical efficacy and safety of LEVI-04 and the clinical development path for LEVI-04.

Neuronal Mechanisms Underlying the Transition of Acute to Chronic Pain and Emerging Drug Targets
Peripheral sensory neurons that relay nociceptive information to the central nervous system show remarkable plasticity following an acute nociceptive insult. This pain plasticity is thought to underlie the development and maintenance of chronic pain, and a key concept of pain plasticity is the development of hyperalgesic priming, where an acute insult can prime pain pathways to produce prolonged and latent hypersensitivity following a subsequent injury. This presentation will discuss the distinct contributions of subsets of primary afferent populations in driving the transition from acute to chronic pain based on rodent models of hyperalgesic priming, where repeated ipsilateral insults to somatic tissue can lead to long-lasting bilateral hypersensitivity. Electrophysiological data from dorsal root ganglia and dorsal horn neurons will outline the discrete roles of the peripheral and central nervous system in the development of acute and chronic pain. Identification of distinct primary afferent subpopulations, and their transcriptomic profiles, that mediate chronic pain is an essential aspect of pain physiology that could help shed light on novel drug targets.

CGRP and Headache – Clinical Implications
In this presentation, Dr. Seifert will discuss the evolution of CGRP compounds and their use within headache medicine. Prior, current, and future research perspectives will be discussed. The context of this talk will focus specifically on migraine and post-traumatic headaches.
Tad Seifert, MD, Director, Sports Neurology Program, Norton Healthcare, Head, NCAA Headache Task Force

A Strategy for Gene Therapy for Chronic Pain
Gene therapy is generally thought of as a way to fix a broken genetic code. For example, Sarepta recently had a gene therapy treatment approved for Duchenne muscular dystrophy, a rare but deadly and irreversible disease in which the gene coding for the dystrophin protein is dysfunctional. Gene therapy approaches can also be applied to conditions where the code is fine, but there is a pathological overexpression of the protein coded. For example, in many chronic pain conditions, we know that there is overexpression of certain genes, including certain encoding sodium channels in the peripheral nerves providing pain input to the CNS. A gene therapy approach in this case would be to decrease expression of the target gene. This presentation will focus on the use of recombinant herpesviral vectors as a means of knocking down expression of pain-associated genes or introducing novel genes into nociceptors. Herpesviruses are optimal for this as they allow for large genetic payload and are neurotropic – naturally targeting the same cells that we want to modify.

Multi-Target-Directed Ligands for the Treatment of Pain
Cannabinoid ligands that target CB1 and/or CB2 receptors possess therapeutic potential for the treatment of an ever-growing numbers of disorders. Currently, the diversity of cannabinoid ligands is very broad and continues to expand rapidly. Whether cannabinoid ligands exert their biological activities via a cannabinoid receptor-dependent or an off-target-mediated mechanism remains unclear. In our efforts to understand and to improve the treatment of pain, we sought to design and synthesize a chemical library of cannabinoid ligands. In our initial lead compound set, we identified T-type Ca2+ channel antagonists that analgesic effects in different in vivo pain models. In this presentation, Dr. Diaz will report details of the design, in vitro characterization, and in vivo testing of this new series of compounds.

VVZ 149 (Opiranserin) and Pain Modulation: Results from an Exploratory Proof of Concept Study of Postoperative Pain after Laparoscopic Colorectal Surgery
Dr. Nedeljkovic will present the results of an exploratory study of patients who received VVZ-149 after undergoing laparoscopic colorectal surgery. Results showed a 34.2% reduction in opioid consumption (24 hr) and remarkably fewer PCA demands in the VVZ-149 group compared to placebo. These and other results suggest that VVZ-149 may have a particular role in reducing the affective component of pain as one of the mechanisms by which it exerts its analgesic efficacy and opioid sparing effects. Dr. Nedeljkovic will also present data from a study of VVZ-149 conducted on patients undergoing laparoscopic or robotic-assisted gastrectomy. This Phase 2 study assessed the preliminary efficacy of VVZ-149 for postoperative pain and opioid sparing as well as its safety profile with intraoperative administration.

Modified Ketamine Analogs and Delivery Systems to Improve Analgesia in Acute Pain
Intranasal ketamine is preferentially used by the U.S. Military in deployed locations to treat acute trauma pain. Ketamine is extensively metabolized to several active and inactive metabolites. Amorsa’s proprietary compounds are based on the selective deuteration of ketamine’s primary active metabolite. These compounds demonstrate improved oral bioavailability, a prolonged duration of action and the potential for reduced CNS side effects. Patented extended release formulations designed to limit ketamine’s CNS side effects and reduce the abuse potential have also been developed. The presentation will cover Amorsa’s pre-clinical development of these novel compounds and patented formulations.
