Impel to Host Investor Conference Call Today at 8:30 A.M. ET

SEATTLE, May 16, 2022 (GLOBE NEWSWIRE) -- Impel Pharmaceuticals (NASDAQ: IMPL), a commercial-stage pharmaceutical company developing transformative therapies for people suffering from diseases with high unmet medical needs, with an initial focus on the central nervous system, today reported financial results for the first quarter ended March 31, 2022 and provided a corporate update.

“We are pleased to see continued strong growth and momentum with Trudhesa®, supported by favorable market access coverage and positive physician and patient feedback,” said Adrian Adams, Chairman of the Board and Chief Executive Officer of Impel Pharmaceuticals. “Trudhesa has garnered around five percent of new branded acute migraine prescriptions in our Super Target population in only six months since launch, and with 35-45 percent of Trudhesa patients being switched from or added to gepants, we believe Trudhesa is filling a significant unmet need in the post-triptan market.”

Adams continued, “To further support the launch of Trudhesa, we entered into a $100 million royalty and debt agreement with Oaktree Capital in March. This non-dilutive capital strengthened our balance sheet, and based on current projections, extends our cash runway into 2024.”

About Impel Pharmaceuticals
Impel Pharmaceuticals is a commercial-stage pharmaceutical company developing transformative therapies for people suffering from diseases with high unmet medical needs, with an initial focus on diseases of the central nervous system. Impel offers and is developing treatments that pair its proprietary POD® technology with well-established therapeutics. In addition to Trudhesa® nasal spray, which is approved in the U.S. for the acute treatment of migraine with or without aura in adults, Impel is also developing INP105 for the acute treatment of agitation and aggression in patients with autism.

About Impel’s Precision Olfactory Delivery (POD®) Technology:
Impel’s proprietary POD® technology is able to deliver a range of therapeutic molecules and formulations into the vascular-rich upper nasal space, believed to be a gateway for unlocking the previously unrealized full potential of these molecules. By delivering predictable doses of drug directly to the upper nasal space, Impel’s precision performance technology has the goal of enabling increased and consistent absorption of drug, overriding the high variability associated with other nasal delivery systems, yet without the need for an injection. While an ideal target for drug administration, to date no technology has been able to consistently deliver drugs to the upper nasal space. By utilizing this route of administration, Impel Pharmaceuticals has been able to demonstrate blood concentration levels for its investigational therapies that are comparable to intramuscular (IM) administration and can even reach intravenous (IV)-like systemic levels quickly, which could transform the treatment landscape for central nervous system (CNS) and other disorders. Importantly, the POD technology offers propellant-enabled delivery of dry powder and liquid formulations that eliminates the need for coordination of breathing, allowing for self- or caregiver-administration in a manner that may improve patient outcome, comfort, and potentially, compliance.

About Trudhesa®
Indication
Trudhesa® is used to treat an active migraine headache with or without aura in adults. Do not use Trudhesa to prevent migraine when you have no symptoms. It is not known if Trudhesa is safe and effective in children.

Important Safety Information

Serious or potentially life-threatening reductions in blood flow to the brain or extremities due to interactions between dihydroergotamine (the active ingredient in Trudhesa) and strong CYP3A4 inhibitors (such as protease inhibitors and macrolide antibiotics) have been reported rarely. As a result, these medications should not be taken together.

Do not use Trudhesa if you:

Before taking Trudhesa, tell your doctor if:

The use of Trudhesa should not exceed dosing guidelines and should not be used on a daily basis. Serious cardiac (heart) events, including some that have been fatal, have occurred following the use of dihydroergotamine mesylate, particularly with dihydroergotamine for injection, but are extremely rare.

You may experience some nasal congestion or irritation, altered sense of taste, sore throat, nausea, vomiting, dizziness, and fatigue after using Trudhesa.
Contact your doctor immediately if you experience:

The risk information provided here is not comprehensive. To learn more, talk about Trudhesa with your healthcare provider or pharmacist.

About INP105:
INP105 is an upper nasal formulation of olanzapine administered using Impel’s novel POD® technology and being developed for the potential treatment of agitation and aggression associated with autism spectrum disorder. The POD® is a novel, simple-to-use device designed to deliver consistent and predictable doses of drug. INP105 delivers olanzapine to the richly vascularized upper nasal space to offer rapid, consistent, and optimized bioavailability that can be administered by the patient or a caregiver. Olanzapine is the most used treatment for acute agitation, but its use is limited to intramuscular injection and in a hospital setting. INP105 is intended to be a preferred choice for the safe and rapid treatment of acute agitation and because it is designed to be non-invasive, it has the potential to expand the treatment setting beyond the emergency room, such as inpatient treatment or community care facilities and the patient’s home.
