VANCOUVER, British Columbia, June 27, 2023 (GLOBE NEWSWIRE) — Algernon Pharmaceuticals Inc. (the “Company” or “Algernon”) (CSE: AGN) (FRANKFURT: AGW0) (OTCQB: AGNPF), a clinical stage pharmaceutical development company, is pleased to announce that it has engaged Maxim Group LLC (“Maxim”) to provide financial advisory and investment banking services, and to assist in identifying and evaluating potential M&A and strategic opportunities, including the potential spin-off of the Company’s NP-120 (“Ifenprodil”) chronic cough research program.
Ifenprodil is an N-methyl-D-aspartate (NMDA) receptor antagonist specifically targeting the NMDA-type subunit 2B (GluN2B), which prevents glutamate signaling. Ifenprodil represents a novel first-in-class potential treatment for chronic cough and is thought to interfere with central signaling in the brain, suppressing the urge to cough.
“We are very pleased to be working with Maxim, and we are especially interested in the potential to achieve significant value for our Ifenprodil asset and for our shareholders, through a spin-off transaction,” said Christopher J. Moreau, Algernon’s Chief Executive Officer. “Ifenprodil represents a novel first-in-class potential treatment for chronic cough, and we are only one Phase 2b study away from the stage of development where Bellus’ camlipixant was acquired by GSK and Afferent’s gefapixant was acquired by Merck.”
Algernon’s Phase 2a Study Data
The decision to advance to a Phase 2b cough study was based on positive data previously reported from the Company’s proof of concept Phase 2a study of idiopathic pulmonary fibrosis (“IPF”) and chronic cough on July 28, 2022, where Ifenprodil showed a significant reduction in cough count. Patients with IPF are usually excluded from trials in refractory chronic cough (“RCC”), and cough in this population is regarded as extremely difficult to treat.
Further analysis revealed:
Chronic Cough Market
According to Data Bridge Market Research analyses, the global chronic cough market was valued at USD $6.15B in 2021 and is projected to grow up to USD $11.38B by 2029.
Merck & Co. obtained the rights to gefapixant, a P2X3 receptor antagonist, as the lead asset in the acquisition of Afferent Pharmaceuticals in 2016. At the time, gefapixant had interim data from a Phase 2b dose-escalation study in RCC. The deal was worth up to USD $1.25 billion.
Bellus Health, which is advancing camlipixant, its own novel P2X3 receptor antagonist, announced on April 18, 2023, that GSK plc signed a deal where they agreed to buy all the outstanding shares in Bellus for USD $14.75 per share in cash with a total deal value estimated at USD $2 billion, confirming the need for better therapies for chronic cough.
Algernon’s Chronic Cough Advisors
Dr. Jacky Smith is a Professor of Respiratory Medicine at the University of Manchester and an Honorary Consultant at Manchester University NHS Foundation Trust. She runs a multi-disciplinary research team whose focus is on understanding mechanisms underlying pathological cough and a regional clinical service seeing patients with refractory chronic cough. Dr. Smith is also the lead medical and scientific advisor to both Merck and Bellus Health for their RCC research programs.
Dr. Peter Dicpinigaitis is board-certified in Internal Medicine, Pulmonary Diseases and Critical Care Medicine. He is a faculty member of the Division of Critical Care Medicine at Montefiore Medical Center and is the founder and director of the Montefiore Cough Center, one of the few specialty centers in the world exclusively committed to the evaluation and management of patients with chronic cough.
About Chronic Cough
Chronic cough is defined as a cough lasting for more than eight weeks in duration and in the United States cough continues to be one of the most common reasons that adults consult medical doctors. Some cases of chronic cough are so debilitating that quality of life is severely impacted leading to depression, anxiety, urinary incontinence, dysphonia, sleep interruption, vomiting, and even rib fractures further adding to the decay in socio-familial dynamics.
Chronic cough is believed to be the result of a hypersensitivity of the cough reflex within the neuronal circuitry that governs the urge to cough, wherein one or more aspects that regulate cough are over-active to stimulus, triggering a cough at abnormal levels. Trials of cough suppressants (Antitussives) have shown differences in response that may reflect differing pathological processes driving cough in different patients.
Experimental Antitussives often only engage a single receptor, while the overall cough response is governed by multiple receptors triggered by a large variety of stimuli. A compound acting centrally, like ifenprodil, where all peripheral messages are sent and coordinated, may achieve a better outcome than what has been achieved in clinical trials.
About NP-120 (Ifenprodil)
Ifenprodil selectively inhibits N-methyl-D-aspartate (“NMDA”) receptors containing the NR2B subunit. They are highly implicated in events such as neuronal plasticity (strengthening of neural pathways) and excitotoxicity (neurotoxic cascade resulting in neuron death).
By inhibiting NMDA receptors, Ifenprodil can diminish excitability of neurons and prevent the relaying of information along neuronal circuitry, including the cough reflex. Ifenprodil may also inhibit the neuroplastic enhancement of central and peripheral cough response neurons.
