Insights

The announcement reveals Pulmatrix's strategic pivot through its merger agreement with Cullgen, expected to close in H1 2025, and plans to divest its entire respiratory and migraine therapeutic portfolio. This represents a complete business transformation from Pulmatrix's inhaled drug delivery focus to Cullgen's protein degradation platform.

The financial picture shows modest revenue growth to $7.8 million (up 6.8% YoY), with significantly reduced R&D expenses of $7.2 million (down 53.5%). This reduction stems from winding down clinical trials and facility closures rather than operational efficiency. G&A expenses increased 20% to $7.8 million, driven by legal/professional services for the merger and employee separation costs.

The $9.5 million cash position is only sufficient to reach the merger closing, indicating runway for independent operations. The $2.6 million loss from MannKind transactions further weakens their financial position.

This transformation effectively means current PULM shareholders are investing in an entirely different business post-merger. Cullgen brings three Phase 1 or near-Phase 1 programs targeting cancer and pain treatment using protein degradation technology—a complete departure from Pulmatrix's respiratory focus. The divestiture of their Phase 2-ready migraine candidate (PUR3100) and proprietary iSPERSE technology signals abandonment of their original business model and intellectual property portfolio with 149 granted patents.

This announcement marks a fundamental redirection in Pulmatrix's business focus, abandoning years of investment in their proprietary iSPERSE™ dry powder inhalation platform in favor of Cullgen's protein degradation technology (uSMITE™).

The divestment of PUR3100, their most advanced clinical candidate, is particularly significant. This inhaled dihydroergotamine for acute migraine had shown promising pharmacokinetics in Phase 1, achieving therapeutic plasma concentrations within just 5 minutes of administration with reduced nausea compared to IV administration. The product was Phase 2-ready with FDA acceptance of the IND and "study may proceed" authorization already secured—representing substantial development value that will now be sold off.

Similarly, PUR1800 (an inhaled narrow spectrum kinase inhibitor for COPD exacerbations) showed positive safety data in Phase 1b, and their antifungal candidate PUR1900 remains under development by partner Cipla outside the US, with Pulmatrix retaining a minimal 2% royalty interest.

The pivot to Cullgen's platform represents an entry into the competitive protein degradation space, with programs targeting cancer and pain that are just entering clinical development. While this field has significant potential, it's a crowded space with multiple approaches from well-capitalized competitors. Post-merger, the company will have three early clinical-stage degrader programs—two in oncology and one in pain management—all at or approaching Phase 1, essentially resetting Pulmatrix's clinical development timeline back several years versus their current portfolio.

Announced merger agreement with Cullgen in November, anticipated to close in the first half of 2025

As part of proposed merger, Pulmatrix intends to divest its assets including its Phase 2-ready acute migraine candidate, PUR3100, and other development candidates based on its iSPERSE™ technology

FRAMINGHAM, Mass., March 21, 2025 /PRNewswire/ -- Pulmatrix, Inc. ("Pulmatrix" or the "Company") (Nasdaq: PULM), a biopharmaceutical company that has focused on the development of novel inhaled therapeutic products intended to prevent and treat migraine and respiratory diseases with important unmet medical needs using its patented iSPERSE™ technology, today announced fourth quarter and year-end financial results for 2024 and provided a corporate update.

Peter Ludlum, Interim Chief Executive Officer of Pulmatrix, commented, "Our focus in the fourth quarter has been to advance the proposed merger with Cullgen, a privately held, clinical-stage biopharmaceutical company applying its proprietary targeted protein degradation uSMITE™ platform to discover and advance therapeutics for the treatment of cancer and other diseases. If successful, the proposed merger would create a Nasdaq-listed company focusing on targeted protein degradation technology with three degrader programs in or about to initiate Phase 1 clinical trials – two for the treatment of cancer and one for the treatment of acute and chronic pain. As part of the proposed merger, Pulmatrix is in a process to divest its clinical assets, including iSPERSE™ and our Phase 2 ready acute migraine product."

Proposed Merger with Cullgen

As previously reported, on November 13, 2024, following a review of strategic alternatives, the Company announced it had entered into an agreement and plan of merger (the "Merger Agreement" and such transaction, the "Merger") with Cullgen Inc. ("Cullgen"). The Merger is anticipated to close in the first half of 2025, subject to the satisfaction of certain closing conditions, among others, however the exact timing of the consummation of the Merger cannot be predicted.

Additional information about the Merger Agreement was previously disclosed on a Current Report on Form 8-K filed with the SEC on November 13, 2024, and in a registration statement on Form S-4 filed with the SEC on February 14, 2025.

Pulmatrix Seeking Divestment of Clinical Assets and Proprietary iSPERSE™ Technology

PUR3100

  • PUR3100 is an orally inhaled dihydroergotamine ("DHE") engineered with Pulmatrix's iSPERSE dry powder inhalation technology for the treatment of acute migraine.
  • In 2023, Pulmatrix announced the Food and Drug Administration's acceptance of an Investigational New Drug ("IND") application for PUR3100 and receipt of a "study may proceed" letter to proceed with a Phase 2 study, positioning PUR3100 as Phase 2-ready. The IND includes a Phase 2 clinical protocol where safety and preliminary efficacy of PUR3100 will be investigated in patients with acute migraine.
  • The planned Phase 2 trial builds on the Phase 1 trial results of PUR3100, which were published in 2024 in a peer-reviewed publication, Headache: The Journal of Head and Face Pain.
  • The study showed that PUR3100 achieved peak exposures in the targeted therapeutic range and time to maximum concentration occurred at five minutes after dosing at all dosing levels. The PUR3100 dose groups also showed a lower incidence of nausea and no vomiting compared to observations of nausea and vomiting in the intravenously ("IV") administered DHE dose group.

PUR1800

  • PUR1800 is a Narrow Spectrum Kinase Inhibitor ("NSKI"), engineered with our iSPERSE™ technology, for the treatment of acute exacerbations in chronic obstructive pulmonary disease ("AECOPD"). In 2023, Pulmatrix presented complete results from a Phase 1b study of PUR1800 for AECOPD, indicating PUR1800 was safe and well tolerated with no observed safety signals. The topline data, along with the results from chronic toxicology studies, support the continued development of PUR1800 for the treatment of AECOPD and other inflammatory respiratory diseases.

PUR1900

  • PUR1900 is the Company's inhaled iSPERSE™ formulation of the antifungal drug itraconazole for indications where an orally inhaled antifungal may provide a therapeutic benefit or fulfill an unmet medical need. Per an updated agreement with its partner Cipla, Pulmatrix has stopped patient enrollment for the Phase 2b study of PUR1900 while Cipla has continued their Phae 2 trial outside the United States. The decision to stop the study was unrelated to any safety concerns. The Phase 2b study had been ongoing since the first quarter of 2023. The Company completed all Phase 2b wind down activities within the third quarter of 2024 as planned.
  • With the study wind down complete, Pulmatrix bears no further financial responsibility for the development of PUR1900 and will receive 2% royalties on any potential future net sales by Cipla outside the United States. Within the United States, Pulmatrix and Cipla will seek to monetize PUR1900.

iSPERSE™ Technology

  • iSPERSE™ particles are engineered with a small, dense and dispersible profile to exceed the performance of traditional dry powder particles as the iSPERSE™ particles have the dispersibility advantages of porous engineered particles. Pulmatrix believes this results in superior drug delivery compared to traditional oral and injectable forms of treatment for certain diseases.
  • As of December 31, 2024, Pulmatrix's patent portfolio related to iSPERSE™ included approximately 149 granted patents, 19 of which are granted U.S. patents, with expiration dates from 2024 to 2037, and approximately 50 additional pending patent applications in the U.S. and other jurisdictions.

Fourth Quarter and Year-End 2024 Financial Results

Revenues increased approximately $0.5 million to $7.8 million for the year ended December 31, 2024, compared to $7.3 million for the year ended December 31, 2023. The increase is primarily related to a contract modification of the Cipla Agreement which resulted in a cumulative catch-up adjustment recorded during the year ended December 31, 2024.

Research and development expenses decreased approximately $8.4 million to $7.2 million for the year ended December 31, 2024, compared to $15.5 million for the year ended December 31, 2023. The decrease was primarily due to winding down the PUR1900 Phase 2b clinical trial, disposal of the Company's lab and facilities lease and employee terminations.

General and administrative expenses increased approximately $1.3 million to $7.8 million for the year ended December 31, 2024, compared to $6.5 million for the year ended December 31, 2023. The increase was primarily due to incurred legal and professional services costs and one-time employee separation costs, partially offset by decreased rent and other operating costs.

The Company recognized a $2.6 million loss on its transactions with MannKind Corporation, which closed during the third quarter of 2024, representing the write-down for the fair value of assets transferred to MannKind Corporation.

The Company's total cash and cash equivalents balance as of December 31, 2024, was $9.5 million. The Company anticipates that its cash position, based on operational efficiencies and prioritization of spending, is sufficient to fund its operations at least through the anticipated closing of the Merger with Cullgen.
