Pursuing strategic alternatives to further leverage iSPERSE(TM) and optimize the potential of PUR3100

FRAMINGHAM, Mass., Aug. 13, 2024 /PRNewswire/ -- Pulmatrix, Inc. ("Pulmatrix" or the "Company") (Nasdaq: PULM), a clinical-stage biopharmaceutical company developing innovative inhaled therapies to address serious central nervous system and pulmonary disease using its patented dry powder inhalation iSPERSE(TM) technology, today announced second quarter financial results for 2024 and provided a corporate update on its clinical assets.

Peter Ludlum, Interim Chief Executive Officer of Pulmatrix, commented, "Our focus in the second quarter has been to continue our cost saving measures, to complete the transactions with MannKind and to continue the wind down of the Phase 2b study for PUR1900. We believe that this has allowed us to reposition ourselves as a virtual company while continuing to focus on strategic alternatives that leverage the potential of PUR3100 and our iSPERSE(TM) technology."

Second Quarter 2024 and Recent Program and Corporate Highlights

PUR3100

    --  PUR3100 is an orally inhaled dihydroergotamine (DHE) engineered with
        iSPERSE(TM) for the treatment of acute migraine. Pulmatrix is currently
        exploring financing or partnership arrangements to develop and initiate
        a potential Phase 2 clinical study for PUR3100.
    --  In 2023, Pulmatrix announced the FDA's acceptance of an 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, which
        were published in 2023 and presented at the American Headache Society's
        65(th) Annual Meeting in June 2023. In May 2024, Pulmatrix announced a
        peer-reviewed publication of Phase 1 clinical results in the 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, engineered with our
        iSPERSE(TM) 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.
    --  Pulmatrix plans to pursue partnership or other alternatives to monetize
        or advance PUR1800.

PUR1900

    --  PUR1900 is the Company's inhaled iSPERSE(TM) formulation of the
        antifungal drug itraconazole for indications where an orally inhaled
        antifungal may provide a therapeutic benefit or fulfill an unmet medical
        need. In agreement with its partner Cipla, Pulmatrix has stopped patient
        enrollment for the Phase 2b study of PUR1900. The decision to stop the
        study was unrelated to any safety concerns. This study had been ongoing
        since the first quarter of 2023. The Company remains on track to
        complete all Phase 2b wind down activities within the third quarter of
        2024.
    --  After the study wind down, Pulmatrix will bear 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.

Second Quarter 2024 Financial Results

Revenues decreased approximately $0.3 million to $1.6 million for the three months ended June 30, 2024, compared to $1.8 million for the three months ended June 30, 2023. The decrease is primarily related to the continued winding down of the PUR1900 Phase 2b clinical trial, for which the Company incurred fewer expenses eligible for reimbursement under its Agreement with Cipla as compared to the corresponding period in the previous year.

Research and development expenses decreased approximately $1.3 million to $2.8 million for the three months ended June 30, 2024, compared to $4.2 million for the three months ended June 30, 2023. The decrease was primarily due to winding down the PUR1900 Phase 2b clinical trial.

General and administrative expenses increased approximately $0.3 million to $2.0 million for the three months ended June 30, 2024, compared to $1.7 million for the three months ended June 30, 2023. The increase was primarily due to an increase in incurred legal costs.

The company recognized a $2.6 million loss on its disposal group of held for sale assets as of June 30, 2024, representing the current period write-down for the fair value of certain assets to be transferred to MannKind Corporation in the third quarter of 2024.

The Company's total cash and cash equivalents balance as of June 30, 2024, was $12.4 million plus $1.4 million in short-term restricted cash, which was released in August 2024, providing additional cash available to use in operations. The Company anticipates that its cash position, based on operational efficiencies and prioritization of spending, is sufficient to fund its operations into the fourth quarter of 2026.
