The Agenda for the 2019 Summit Has Not Yet Been Announced

Presentations From our 2018 Summit Included:

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.

Learning Healthcare Systems to Enable Real World Research Discovery, Clinical Innovation and Optimal Patient Care
In response to the Institute of Medicine’s Report Relieving Pain in America, Stanford has developed and implemented the Collaborative Health Outcomes Information Registry (CHOIR) system. This open source, open standard and free data-collection software was created in partnership with the National Institutes of Health. Relieving Pain in America made clear that there is not enough data being collected on pain patients. CHOIR begins to fix this problem. It allows doctors to collect qualitative information on pain patients in a safe, secure, and easy-to-use system. Doctors can then use that information to better treat each individual patient by, say, seeing charts about how a patient’s pain responds to treatment over time. Doctors can also take data from many patients together to learn more about pain conditions and hopefully develop better treatments. Dr. Mackey will share with the audience details regarding this program and findings to date.

Multi-Target-Directed Ligands for the Treatment of Pain
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.

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

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. 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.

Current and Future Advances in Intrathecal Analgesic Drug Targeting 
While the experience of pain, as does consciousness, reflects supraspinal processing, this processing is driven by the encoding of sensory information at the spinal level. Work on the biology of nociceptive processing has shown that the input output function of the spinal cord relevant to the pain state may be modified in a surprisingly specific fashion by the local targeting of spinal systems though neuraxial drug delivery. Following demonstration of the effects of spinal opiates, the complexity of dorsal horn pharmacology has evolved to reveal drugable targets present at the level of the first and second order neuron that can robustly regulate pain processing. Development of chronic delivery systems and the evolving development of intrathecal toxins and transfection methodologies suggest the utility of regulated effects upon pain processing in managing persistent pain states.

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.

Discovery and Characterization of NaV1.7 Inhibitors Patterned on Natural Pore Blockers 
The voltage-gated sodium channel NaV1.7 is a genetically-validated target for analgesic drug development; humans lacking functional NaV1.7 are unable to experience most types of pain. Efforts to discover selective inhibitors of NaV1.7 have been complicated by the high homology between NaV isoforms, and results from early clinical trials have been disappointing. This presentation will disclose preclinical results generated with a novel class of NaV1.7 inhibitors patterned on natural products that bind to the extracellular vestibule of the sodium channel. Certain compounds exhibit >200-fold selectivity over other human NaV isoforms and reduce noxious thermal sensitivity in animal models. The implications of these results on outstanding questions in NaV1.7 drug development will be discussed.

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.

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.
