MDP Medexus Pharmaceuticals Inc

Medexus Pharmaceuticals (Medexus) (TSX: MDP) (OTCQX: MEDXF) wishes to inform investors that the company has reached an agreement with the provincial government of Quebec for government-sponsored coverage of Cuvposa (glycopyrrolate oral solution 1mg/5mL). Cuvposa will be listed for public reimbursement on the Public Prescription Drug Insurance Plan of the Régime de l’Assurance Maladie du Québec, or RAMQ, starting February 1, 2023.

Cuvposa is indicated in Canada to reduce chronic severe drooling in pediatric patients 3 to 18 years of age with neurologic conditions associated with problem drooling, such as cerebral palsy. Listing Cuvposa fills a health need recognized as being moderate to high in vulnerable and underserved pediatric populations in Canada who are affected by this condition.

Dr Pierre Marois, Pediatric Physiatrist at Montreal’s Ste-Justine Hospital, commented: “Chronic severe drooling, or sialorrhea, is an often-underestimated condition in pediatric patients who are also managing significant neurologic conditions. It can result in dysphagia and impact respiratory health – but can also affect the social and emotional development of these children and the wellbeing of their caregivers and families, contributing to the substantial burden of the underlying conditions.”

“The limited number of available treatment options means that chronic severe drooling is often poorly managed,” added Jean-Claude Beaudoin, Vice President—Sales & Marketing at Medexus. “We are therefore proud to make Cuvposa available to more patients in Quebec through this new partnership with the Quebec government. We believe greater access to Cuvposa will help more people seeking to manage the ancillary effects of neurologic conditions, which can have a significant impact on their wellbeing.”

About Cuvposa

Cuvposa (glycopyrrolate oral solution 1mg/5mL) is indicated to reduce chronic severe drooling in patients 3 to18 years of age with neurologic conditions associated with problem drooling, such as cerebral palsy. Chronic severe drooling may also be diagnosed in patients with other neurological disorders, such as severe developmental delay, autism spectrum disorders, sensory impairments, traumatic brain injuries, or neurogenetic and metabolic disorders.

The rate of cerebral palsy incidence in Canada is estimated at around 0.3 per 1,000 for children less than 20 years old, with newly diagnosed cases expected to increase to nearly 2,200 in 2031 and the number of people living with cerebral palsy increasing to more than 94,000. Over this period, Canadians with cerebral palsy are expected to continue to experience, among other things, a reduced quality of life and a rising need for supportive services including informal care.

Glycopyrrolate indirectly reduces the rate of salivation by preventing the stimulation of acetylcholine muscarinic receptors located on peripheral tissues such as salivary glands. Dry mouth, vomiting, constipation, flushing of the face or skin, headache, problems urinating, and rapid heartbeat are the most commonly reported side effects of Cuvposa. For more information about Cuvposa, including important safety information, see the product monograph. Medexus holds exclusive distribution rights to Cuvposa in Canada.

Cuvposa is approved by Health Canada for sale and use in Canada only and is not intended for export outside Canada. Medexus makes no representation that Cuvposa is appropriate for, or authorized for sale to or use by, individuals who are not located in Canada.
