SEATTLE, March 24, 2023 (GLOBE NEWSWIRE) -- Impel Pharmaceuticals Inc.(NASDAQ: IMPL),a commercial-stage pharmaceutical company with a mission to develop transformative therapies for people suffering from diseases with high unmet medical needs, today reported financial results for the fourth quarter and full year ended December 31, 2022 and provided a business update.

“We continued to see strong growth in Trudhesa^® prescriptions as we moved into 2023. The Company’s priority objective is to maximize the growth potential of Trudhesa in a market where we already hold 4.3 percent of total branded acute migraine prescriptions among Trudhesa prescribers,” said Adrian Adams, Chairman of the Board and Chief Executive Officer of Impel Pharmaceuticals. “Additionally, we continue to see increased productivity and efficiency from the field force expansion we completed in July 2022. This, together with the increased number of prescriptions reimbursed and resultant positive impact on revenue growth, points to the value creation opportunity with Impel.”

Recent Corporate Highlights
Trudhesa^® (Dihydroergotamine Mesylate) Nasal Spray (0.725 Mg Per Spray)

• To-date, Trudhesa continues a strong trajectory with more than 58,400 prescriptions generated in 2022. Based on third-party data, it is estimated that at the end of December Trudhesa accounted for 4.3 percent of branded acute migraine prescriptions (nTRx) among prescribers.
• We continue to see the benefits of the increased sales force from last July. New Trudhesa prescriptions increased by 24 percent from Q3 to Q4 2022 driven by an expanded, more efficient salesforce. Additionally, the existing (n=60) and new (n=30) sales representatives increased monthly new patients starts by 29.7 percent and 45.8 percent, respectively, from October through December 2022, for a total increase in monthly new patient starts of more than 35 percent during this time period.
• Reimbursement of all shipments is 60 percent for the fourth quarter 2022. Refill rates have remained consistently high with 63 percent at the end of 2022.
• Impel will have a presence at the American Academy of Neurology (AAN) Annual Meeting taking place in Boston, April 22-27, 2023 and at the American Headache Society (AHS) Annual Scientific Meeting taking place in Austin, Texas, June 15-18, 2023.

Clinical Developments

• In November 2022, Impel published a manuscript in The Journal of Headache and Pain which detailed results from a review developed to illustrate the variability of recurrence rates depending on the definition of “recurrence” for widely used acute treatments for migraine.
• Also in November 2022, Impel published a manuscript in the Journal of Aerosol Medicine and Pulmonary Drug Delivery which showed that clinical studies of Trudhesa demonstrated a favorable pharmacokinetic profile, consistent and predictable dosing, rapid systemic levels known to be effective (similar to other DHE mesylate clinical programs), safety and tolerability on the upper nasal mucosa, and high patient acceptance. Additionally, the Precision Olfactory Delivery (POD^®) technology may have the potential to overcome the limitations of traditional nasal delivery systems, while utilizing the nasal delivery benefits of gastrointestinal tract avoidance, rapid onset, patient convenience, and ease of use.
• In October 2022, Impel published a manuscript in the Annals of Otolaryngology and Rhinology Outreach detailing results from first-of-their-kind safety assessments designed for and used in the pivotal STOP 301 study of Trudhesa.
  

Financial Results for Fourth Quarter and Year End 2022

• Net Product Revenue: The Company’s net revenue from sales of Trudhesa was $5.0 million and $12.7 million for the fourth quarter and full year 2022, respectively. This compared to net revenues of $0.6 million and $0.7 million for the fourth quarter and full year 2021, respectively. Shipments of Trudhesa were initiated to specialty pharmacies in late September 2021 ahead of the October 2021 commercial launch.
• Research and Development (R&D) Expenses: R&D expenses were $0.7 million and $11.5 million for the fourth quarter and full year 2022, respectively, compared with $4.5 million and $20.6 million for the same periods of 2021, respectively. The decrease in R&D expense was due to the return of the $2.9 million new drug application fee from the U.S. Food and Drug Administration (FDA) received in the fourth quarter of 2022 and a reduction in Trudhesa clinical expenses as the Phase 3 STOP 301 study was closed. This was partially offset by an increase in spending for the clinical development of INP105.
• Selling, General and Administrative (SG&A) Expenses: SG&A expenses were $20.3 million and $77.9 million for the fourth quarter and full year 2022, respectively, compared with $19.9 million and $50.9 million for the same periods of 2021, respectively. The increase in SG&A spending was primarily due to the continued ramp up in spending to support the commercial, sales and marketing activity in support of the Trudhesa launch.
• GAAP Net Loss: Net losses for the fourth quarter and full year 2022 were $23.0 million and $106.3 million, respectively, or $0.97 and $4.53 per common share, respectively. This compared to net losses of $24.7 million and $76.7 million, respectively, or $1.07 and $5.25 per common share, respectively, for the same periods in 2021.
• Non-GAAP Net Loss Per Share: Non-GAAP Net Loss Per Share for the fourth quarter and full year 2022 were $0.97 and $4.53, respectively, compared to a Non-GAAP Net Loss Per Share of $1.07 and $3.68, respectively, for the same periods in 2021. Non-GAAP Pro Forma Net Loss Per Share gives effect to the Company’s reverse stock split, the shares of common stock issued in its April 2021 IPO, shares exchanged for previously issued and outstanding stock warrants of Impel, and the conversion of the Company’s convertible preferred stock and its convertible notes into shares of common stock as if such conversions occurred at the beginning of each period presented. Non-GAAP Net Loss Per Share excludes the change in fair value of the convertible notes and interest expense on Impel’s convertible notes, the effect of accretion on its redeemable convertible preferred stock and the change in fair value of its redeemable convertible preferred stock warrants, all of which converted to shares of common stock in the Company’s April 2021 IPO. Please refer to the section in this press release titled "Reconciliation of GAAP and Non-GAAP Results" for details.
• Cash on Hand/Cash Runway:As of December 31, 2022, Impel had approximately $60.7 million in cash and cash equivalents. The Company believes, based on its current operating plan, that it has sufficient capital to fund operations into the third quarter of 2023.

Trudhesa Guidance for 2023

• The Company projects Trudhesa will deliver prescriptions within the range of 80,000 – 110,000 TRx for full year 2023.

About Impel Pharmaceuticals
Impel Pharmaceuticals is a commercial-stage pharmaceutical company developing transformative therapies for people suffering from diseases with high unmet medical needs. Impel offers treatments that pair its proprietary POD^® technology with well-established therapeutics. In September 2021, Impel received U.S. FDA approval for its first product, Trudhesa^® nasal spray, which is approved in the U.S. for the acute treatment of migraine with or without aura in adults. In addition to Trudhesa, the Company continues to address patient needs via licensing and partnerships.

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 a broad range of 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.
