Trudhesa is the First and Only Therapeutic to Use POD® Technology to Deliver Dihydroergotamine Mesylate (DHE)—a Proven, Well-Established Therapeutic—to the Vascular-Rich Upper Nasal Space
Trudhesa is Available Through Trudhesa Direct™, Which Will Provide Hassle-Free Prescribing, Savings and Home Delivery Facilitated by Digital Pharmacy Partners Carepoint Pharmacy and Phil, Inc.
Eligible, Commercially-Insured Patients Will Be Automatically Enrolled in a Patient Savings Program to Obtain Trudhesa
SEATTLE, Sept. 28, 2021 (GLOBE NEWSWIRE) -- Impel NeuroPharma, Inc. (NASDAQ: IMPL), a commercial-stage biopharmaceutical company developing transformative therapies for people suffering from diseases with high unmet medical needs, with an initial focus on the central nervous system (CNS), today announced that Trudhesa™ (dihydroergotamine mesylate) nasal spray (0.725 mg per spray) is now available for prescription. The U.S. Food and Drug Administration (FDA) approved Trudhesa earlier this month for the acute treatment of migraine with or without aura in adults.
Using Impel’s innovative Precision Olfactory Delivery (POD®) technology, Trudhesa gently delivers dihydroergotamine mesylate (DHE)—a proven, well-established therapeutic—quickly to the bloodstream through the vascular-rich upper nasal space.1 Trudhesa bypasses the gut and potential absorption issues, offering rapid, sustained, and consistent symptom relief without injection or infusion, even when administered hours after the onset of a migraine attack.2
Trudhesa is now available through Trudhesa Direct™, a streamlined, customized, end-to-end process that provides hassle-free prescribing, savings, and home delivery. The digital pharmacy partners, Carepoint Pharmacy and Phil Inc., facilitate the process beginning with e-prescribing and automatic enrollment of eligible, commercially-insured patients in the Trudhesa Direct Savings Program to obtain Trudhesa. Once our pharmacy partners receive the e-prescription, patients will be notified via digital communications that their prescription has been processed and receive their medication via convenient, free, home delivery.
“We are excited and proud to launch Trudhesa within weeks of FDA approval. Trudhesa utilizes our pioneering POD technology to optimize delivery of DHE to the upper nasal space, giving migraine patients what they want—rapid, sustained, and consistent relief with one dose, self-administered, anytime, anywhere,” said Adrian Adams, Chairman and Chief Executive Officer, Impel NeuroPharma. “Trudhesa is being made available via Trudhesa Direct, a streamlined process that includes automatic enrollment in the patient savings program for eligible, commercially-insured patients. We look forward to working with our digital pharmacy partners to deliver Trudhesa seamlessly to patients at home, so it’s there when they need it.”
With each Trudhesa prescription, patients will receive four single-use products, each comprised of a POD device and a DHE vial packaged in a compact case. Most patients on Trudhesa achieve pain relief with one single dose.
“Our company, Carepoint Pharmacy, was built to provide patients with a simple and patient-first pharmacy experience that makes getting prescriptions easy, fast and reliable. When patients are dealing with the unpredictability of a condition like migraine, we offer assurance that their medication will arrive quickly, straight to their home, for convenience they can trust,” said Bhavesh Patel, PharmD, Chief Executive Officer, Carepoint Pharmacy.
“Phil provides an efficient and value-driven experience for patients to get timely and affordable access to their medications," said Deepak Thomas, founder and Chief Executive Officer of Phil, Inc. "The challenges in this space reach far beyond the patient, and our goal is to simplify this complex ecosystem to deliver positive outcomes for all stakeholders.”
Impel has also established a Patient Assistance Program for eligible patients with financial hardship or limited or no insurance. For more information, please visit www.TRUDHESA.com.
About STOP 301
The New Drug Application for Trudhesa included the results of the Phase 3, open-label, pivotal safety study, STOP 301, which is the largest longitudinal study ever conducted with DHE using nasal spray delivery.3 More than 5,650 migraine attacks were treated over 24 or 52 weeks during the study. The primary objective of the study was to assess the safety and tolerability of Trudhesa. Exploratory objectives included efficacy assessments of migraine measures and a patient acceptability questionnaire. In the trial, Trudhesa was generally well tolerated and exploratory efficacy findings showed it provided rapid, sustained, and consistent symptom relief. Unlike some oral acute treatments that need to be taken within one hour of attack onset to be most effective, the STOP 301 study reported Trudhesa offered consistent efficacy even when taken late into a migraine attack.4
There were no serious Trudhesa-related treatment-emergent adverse events (TEAEs) observed in the STOP 301 study and the majority of TEAEs were mild and transient in nature.4 Some of the most frequently reported Trudhesa-related TEAEs (≥2%) during the entire 52-week study period were nasal congestion (17.8%), nausea (6.8%), nasal discomfort (6.8%), abnormal olfactory test (6.8%) and vomiting (2.7%).5
In the STOP 301 study, patient-reported exploratory efficacy findings reported that more than a third of patients (38%) had pain freedom,6 two-thirds (66%) had pain relief,7 and more than half (52%) had freedom from their most bothersome migraine symptom8 at two hours after their first dose of Trudhesa. For one in six patients (16%), pain relief started as early as 15 minutes.7 Of patients who were pain free at two hours after their first migraine attack, 98 percent were still pain free at 24 hours,11 and 95 percent were still pain free through two days respectively, during weeks 21-24.9 The great majority of patients (84%) reported that Trudhesa was easy to use10 and preferred it over their current therapy.11
About Migraine and The Importance of Non-Oral Acute Treatment Options
Approximately 31 million adults in the U.S. are living with migraine,12,13 which is characterized by recurrent episodes of moderate to severe head pain and associated with nausea, vomiting and sensitivity to light and sound. Migraine is the second most common cause of disability in the world and the most common cause of disability among young women.13
In a 2017 survey of nearly 4,000 U.S. patients using oral acute prescription medication for migraine, 96 percent said they were dissatisfied with at least one aspect of their treatment, including lack of sustained relief, inconsistent relief, and lack of relief from a rapid-onset attack. Nearly half (48%) said they can still have pain two hours after taking medication and 38 percent say their headache returns within 24 hours of getting relief.14
The high prevalence of related GI conditions among people with migraine may require alternative routes of medication delivery. Evidence suggests 80 percent of people with migraine experience gastroparesis, delayed emptying of the stomach, which may delay or reduce the absorption of oral medications.15,16 Additionally, more than 70 percent of people with migraine experience nausea and nearly 30 percent experience vomiting.4 The American Headache Society guidelines recommend a non-oral therapy for patients who have limited or no response to oral medicine.17
About Trudhesa™ (dihydroergotamine mesylate) Nasal Spray
Trudhesa™ (dihydroergotamine mesylate) nasal spray (0.725 mg per spray) is approved by the U.S. Food and Drug Administration for the acute treatment of migraine with or without aura in adults in the U.S. Using Impel’s proprietary Precision Olfactory Delivery (POD®) technology, Trudhesa gently delivers dihydroergotamine mesylate (DHE)—a proven, well-established therapeutic18—quickly to the bloodstream through the vascular-rich upper nasal space. Trudhesa bypasses the gut and potential absorption issues, offering the potential for rapid, sustained, and consistent relief without injection or infusion, even when administered hours after the start of a migraine attack.19
Trudhesa is a single use, drug-device combination product containing a vial of DHE (4 mg DHE in a 1 mL solution that is clear and colorless to faintly yellow) and a POD® device. Prior to initiation of Trudhesa, a cardiovascular evaluation is recommended. For patients with risk factors predictive of coronary artery disease who are determined to have a satisfactory cardiovascular evaluation, it is strongly recommended that administration of the first dose of Trudhesa take place in the setting of an appropriately equipped healthcare facility.
Trudhesa is designed to be self-administered. Once assembled, Trudhesa should be primed before initial use by releasing 4 sprays. A patient should use Trudhesa immediately after priming. The recommended dose of Trudhesa is 1.45 mg administered as two metered sprays into the nose (one spray of 0.725 mg into each nostril). The dose may be repeated, if needed, a minimum of 1 hour after the first dose. A patient should not use more than 2 doses of Trudhesa within a 24-hour period or 3 doses within a 7-day period. A patient should use or discard Trudhesa within 8 hours once the vial has been opened or the product has been assembled. A consumer assembly video is available on www.TRUDHESA.com and please refer to the Instructions for Use for more details.
The most common adverse reactions (incidence ≥2%) to Trudhesa were nasal congestion, nasal discomfort, nausea, product taste abnormal, and product package associated injury.

About Dihydroergotamine Mesylate (DHE)
Dihydroergotamine Mesylate (DHE) was approved for the treatment of migraine in 194618 and has more than 70 years of therapeutic use.18 Migraine treatment with DHE has demonstrated efficacy independent of when the treatment is initiated.9 Unlike other available treatments for migraine, DHE is known to bind to multiple receptors theorized to be implicated in migraine onset and duration.9
