Windtree Therapeutics Reports Fourth Quarter and Year-End 2023 Financial Results and Provides Key Business Updates

WARRINGTON, Pa., April 17, 2024 (GLOBE NEWSWIRE) -- Windtree Therapeutics, Inc. (“Windtree” or “the Company”) (NasdaqCM: WINT), a biotechnology company focused on advancing early and late-stage innovative therapies for critical conditions, today reported financial results for the fourth quarter and fiscal year ended December 31, 2023 and provided key business updates.

“The end of 2023 and the past few months have been very productive at Windtree as we advanced clinical programs, executed a license for cardiovascular assets, took actions to strengthen our balance sheet and, most recently, acquired a novel oncology preclinical atypical protein kinase C iota inhibitor (aPKCi inhibitor) platform from Varian Biopharmaceuticals. These actions represent the first part of a portfolio optimization strategy and a potentially transformative next step for Windtree,” said Craig Fraser, CEO. “Later this year, we plan to read out data from both of our ongoing Phase 2 istaroxime trials in cardiogenic shock while we are also supporting our regional partner, Lee’s Pharmaceutical, in starting a Phase 3 program in acute heart failure. In addition, we are actively engaged in global partnership discussions for istaroxime, with the objective of partnering to help advance istaroxime through existing and future clinical trials and gaining potential deal revenue. Given the intent to have the resource intensive, late stage istaroxime program advanced by a larger company, by adding the innovative aPKCi inhibitor platform to our early-stage pipeline, we plan to strengthen our focus on advancing our preclinical programs, including our selective SERCA2a activators. We believe partnering our istaroxime program both regionally and globally, has the potential to allow us to better advance our other pipeline assets and help us to significantly reduce our cash burn, extend runway and leverage our experienced team to advance our innovative early-stage platforms.” Mr. Fraser further added, “Mid to longer term, we believe there could be opportunity to leverage our internal programs, partner deal revenue, a strengthened balance sheet and public company liquidity to selectively execute other potential acquisitions and/or strategic transactions to grow the business and its value.”

“The R&D and clinical team has been busy this period. We advanced the istaroxime program in cardiogenic shock with two clinical trials. First, we progressed clinical execution of the SEISMiC Extension Study in the U.S., Europe and Latin America. We also initiated a study of istaroxime in more severe SCAI Stage C cardiogenic shock patients. Earlier this year, we announced preclinical data describing a reduction in arrythmias with both istaroxime and a pure SERCA2a activator in a rat heart ischemia-reperfusion model,” said Dr. Steve Simonson, Chief Medical Officer of Windtree. “Next, we intend to integrate our newly acquired aPKCi inhibitor into our preclinical portfolio, which we believe has an exciting preclinical data package with two formulations in development. We plan to progress the IND-enabling activities for a topical and oral formulation while we create a comprehensive development plan focused on malignancies with unmet needs that are targets for this mechanism of action. While there is scientific rationale for potential broad application of this mechanism of action, we believe there will be options for targeted disease selection and differentiation due to the potential for high target specificity and the opportunity for a topical formulation to treat various cutaneous malignancies. We are assessing our new asset platform and look forward to communicating our future development plans later this year.”

Key Business Update

●		Entered into an asset purchase agreement with Varian Biopharmaceuticals, Inc. (“Varian”) on April 2, 2024 to acquire certain of its assets, including a proprietary aPKCi inhibitor. The Company also completed a $1.5 million convertible note bridge financing.

Select Fourth Quarter 2023 Financial Results

Research and development expenses were $3.1 million for the fourth quarter of 2023, compared to $1.2 million for the fourth quarter of 2022. The increase in research and development expenses was primarily due to costs related to the execution of the SEISMiC Extension trial of istaroxime for the treatment of early cardiogenic shock and to $0.9 million in accrued payments to Philip Morris USA Inc. and Philip Morris Products S.A. related to amendments to our license agreements.

General and administrative expenses for the fourth quarter of 2023 were $1.9 million, compared to $2.2 million for the fourth quarter of 2022. The decrease in general and administrative expenses is primarily due to (i) a decrease of $0.4 million in non-cash stock-based compensation expense related to headcount reductions and the timing of grants; (ii) a decrease of $0.3 million in insurance and professional fees; and (iii) a decrease of $0.1 million in personnel costs due to headcount reductions; partially offset by (iv) the reversal of $0.5 million in incentive bonus expense during the fourth quarter of 2022.

For the fourth quarter ended December 31, 2023, the Company reported an operating loss of $5.0 million, compared to an operating loss of $10.8 million in the fourth quarter of 2022. Included in operating loss for the fourth quarter of 2022 is a non-cash loss on impairment of intangible assets related to rostafuroxin of $6.8 million and a related $1.4 million deferred income tax benefit and a non-cash loss on impairment of goodwill of $0.5 million.

The Company reported a net loss of $5.2 million ($0.95 per basic share) on 5.4 million weighted-average common shares outstanding for the quarter ended December 31, 2023, compared to a net loss of $9.7 million ($13.01 per basic share) on 0.7 million weighted average common shares outstanding for the comparable period in 2022.

Select 2023 Year-End Financial Results

Research and development expenses were $8.3 million for the year ended December 31, 2023, compared to $11.1 million for the year ended December 31, 2022. The decrease in research and development expenses is primarily due to (i) a decrease of $3.0 million related to the KL4 surfactant platform, inclusive of $1.4 million in personnel cost reductions, as the Company continues to focus its resources on the development of its istaroxime pipeline; (ii) a decrease of $0.7 million for expenditures related to the development of istaroxime for AHF; and (iii) a decrease of $0.4 million in non-cash stock-based compensation expense related to headcount reductions and the timing of grants; partially offset by (iv) $0.9 million in accrued payments to Philip Morris USA Inc. and Philip Morris Products S.A. in 2023 related to amendments to our license agreements; and (v) an increase of $0.4 million as we continue the SEISMiC Extension trial of istaroxime for the treatment of early cardiogenic shock.

General and administrative expenses for the year ended December 31, 2023 were $9.2 million, compared to $10.8 million for the year ended December 31, 2022. The decrease in general and administrative expenses is primarily due to (i) a decrease of $1.4 million in non-cash stock-based compensation expense related to headcount reductions and the timing of grants; (ii) a decrease of $0.6 million in personnel costs due to headcount reductions; and (iii) a decrease of $0.4 million in insurance costs; partially offset by (iv) an increase of $0.4 million in professional fees; and (v)  $0.4 million in severance expense related to a former executive.

For the year ended December 31, 2023, the Company reported an operating loss of $20.6 million, compared to an operating loss of $41.3 million for the year ended December 31, 2022. Included in operating loss for the year ended December 31, 2023 is a non-cash loss on impairment of goodwill of $3.1 million. Included in operating loss for the year ended December 31, 2022 is a non-cash loss on impairment of goodwill of $12.6 million and a non-cash loss on impairment of intangible assets related to rostafuroxin of $6.8 million and a related $1.4 million deferred income tax benefit. 

The Company reported a net loss of $20.3 million ($5.24 per basic share) on 3.9 million weighted-average common shares outstanding for the year ended December 31, 2023, compared to a net loss of $39.2 million ($62.23 per basic share) on 0.6 million weighted average common shares outstanding for the comparable period in 2022.
