Nocion Therapeutics launches to selectively silence pain and itch neurons


April 17, 2019 / Cambridge, MA – Today, Nocion Therapeutics announced plans to develop novel pharmaceuticals that will provide targeted, robust and sustained relief for the treatment of serious medical conditions including cough, itch, pain and inflammation.  These pharmaceuticals are highly selective, locally confined, and silence sensory neurons activated by noxious stimuli, without inhibiting neurons mediating movement or touch.  The approach is based on Nocion Therapeutics’ unique understanding of how sensory neurons respond to noxious stimuli.  The company’s mission is to alleviate suffering for the millions of people with conditions arising from the activation of these neurons.

“Our novel approach to selectively inhibiting neurons, resulting from a fundamental understanding of how the body responds to insult, will result in differentiated therapeutics addressing a host of unmet medical needs,” said Dr. Richard Batycky, CEO. “A confluence of world-class founders and venture partners positions Nocion on the right path to have a meaningful impact on patients’ lives.”

Addressing activated sensory neurons at the molecular level

Academic research led by two of Nocion’s scientific founders, Bruce Bean, PhD, and Clifford Woolf, MB, BCh, PhD, identified a novel class of sodium channel inhibitors that inhibits signaling in activated pain or itch neurons but spares all other neurons. The researchers, based at Harvard University and Boston Children’s Hospital, discovered sodium channel inhibitors modified to be positively charged that could enter neurons by passing through large-pore channels – including TRP and P2X channels – that are up-regulated and activated in inflamed nociceptors.

With support from Harvard’s Blavatnik Biomedical Accelerator and Boston Children’s Hospital’s Technology Development Fund, the collaborating labs demonstrated that this approach can selectively inhibit active sensory neurons that are responding to external insult. The charged sodium channel inhibitors, known as nocions, are designed to only enter activated nociceptors through large-pore channels that exclusively open in response to pain and inflammation.  Once inside, nocions block all sodium channels and electrical activity of the neurons. Unlike current standards of care, nocions do not cause general numbness nor loss of motor function seen with conventional local anesthetics. Finally, due to their chemical nature, nocions can generate a robust effect that has not yet been observed by selective block of either Nav 1.7 sodium channels or specific large-pore channels.  This is because nocions can target activated sensory neurons using any large-pore channel as a doorway in and block all sodium channels in these cells.

“We can use the large-pore channels opened by painful stimuli or inflammatory mediators as Trojan horses to deliver drug molecules into the cells and stop their electrical activity,” said Dr. Bean. “The large-pore channels instigate the firing of the cells, but they can also be used to quench it.”

Nocion’s scientific founders are Dr. Bruce Bean, who is the Robert Winthrop Professor of Neurobiology at Harvard Medical School (HMS); Dr. Clifford Woolf, a Professor of Neurobiology and of Neurology and Director of the F.M. Kirby Neurobiology Center and Neurobiology Program at Boston Children’s Hospital and HMS; and Dr. Bruce Levy, MD, Chief of the Division of Pulmonary and Critical Care Medicine at Brigham and Women’s Hospital, Medical Director of the Brigham Lung Center, and the Parker B. Francis Professor of Medicine at HMS.

Activated sensory neurons underlie numerous conditions

Globally, cough, itch, pain and inflammation drive tens of millions of patients to the doctor every year. For cough alone, approximately 30 million Americans per year seek care in the outpatient setting. 

To advance respiratory indications, Dr. Woolf and Dr. Bean joined forces with Dr. Levy, with support from Boston Biomedical Innovation Center, to show that the team’s approach worked in in vivo models of lung inflammation and cough.

“People may not realize that cough is the presentation of itch in the lung. Medications that could work for itch and pain, such as sodium channel inhibitors, have a history of being used in pulmonary indications in clinical practice, including in my own. The unique molecular approach to selectively silence activated nociceptors, developed by my co-founders, addresses many of the limitations of traditional therapeutics in the class that prevent broader utilization, and may prove to offer better effects for patients,” said Dr. Levy. “We’re hopeful that these innovations may be applicable in many tissues and clinical conditions in the skin, lungs, GI tract, mouth, eye, and beyond to help alleviate patient suffering.”

Beyond the cough, itch, pain and inflammation indications that are directly related to the activation of sensory neurons, indirect activation can set off a feedback cycle through the release of pro-inflammatory neuropeptides that promote conditions like asthma, inflammatory bowel disease, dermatitis, esophagitis, and dry eye. 

Company formation

Nocion Therapeutics has raised a $27MM Series A led by Canaan and F-Prime Capital Partners with participation from Partners Innovation Fund, and BioInnovation Capital.  The capital finances the company from discovery through clinical proof of concept in patients.

Tom Beck, MD, Executive Partner at F-Prime Capital Partners, and Julie Grant, Partner at Canaan, teamed up to form and spin out Nocion. “Rolling our sleeves up with exceptional scientists to build a scientific discovery into a robust company is a sweet spot for both Canaan and F-Prime,” noted Grant. “Tom and I are delighted with the progress to date and formation of an esteemed executive team, which is uniquely qualified to execute upon the promising science from Harvard and Boston Children’s Hospital.” Dr. Beck adds, “I have had the pleasure of working with this group of outstanding scientists for the past several years.  It is truly exciting to see their work mature to the point where it can serve as the basis of this exciting new company.”

Forming Nocion’s initial executive team are Dr. Richard Batycky, CEO and Dr. Jim Ellis, CSO.  Dr. Batycky comes to Nocion with over two decades of experience in drug development across an array of platforms, disease states and registered products, and has been with several start-ups from founding through acquisition. Most recently, he was a founder of Civitas Therapeutics where their lead asset—a novel dry powder inhalation therapy to treat motor issues in Parkinson’s patients—has been approved by the FDA as InbrijaTM.  Dr. Ellis joins with over 20 years of leadership experience in drug discovery in multiple therapeutic areas, working in organizations from biotech startups to large pharma. Most recently, Dr. Ellis led GSK’s Innovation Hub in Cambridge after serving as Vice President and Head of GSK’s Sirtuin Discovery Performance Unit.

Working with Harvard’s Office of Technology Development, Nocion was founded on an exclusive license to foundational intellectual property from Harvard University and Boston Children’s Hospital to develop therapeutics.

“Innovations in how clinicians treat pain are long overdue,” said Isaac Kohlberg, Harvard’s Chief Technology Development Officer and Senior Associate Provost. “We’re thrilled that a decade-long collaboration between researchers at Harvard University and Boston Children’s Hospital has borne fruit in the form of a truly novel approach to treating neurogenic inflammation. We look forward to seeing this potential therapeutic advance toward clinical development.”

Nocion closed its seed financing in the first quarter of 2018 and is in operations at LabCentral in Cambridge, Massachusetts.  Nocion is currently optimizing and expanding on the initial set of small molecule candidates to select leads for multiple indications.


Nocion Therapeutics is a biopharmaceutical company developing novel treatments for silencing neurons. The company’s platform of unique molecular entities selectively affects inflamed nociceptors. Treatment using this approach aims to provide more durable and robust local analgesic effects while minimizing numbness or paralysis and other systemic off-target effects. The company’s mission is to safely alleviate suffering for millions of patients with conditions arising from activated sensory neurons. For more information, visit:
