MannKind to Establish Boston-Area Research & Development Foothold and Expand Portfolio of Dry Powder Inhalation Technology in Transaction With Pulmatrix

• Immediate opportunity to increase capacity for formulation and early asset development in upgraded Boston area R&D space
• Non-cash deal includes royalty-free iSPERSE^™ technology license in exchange for access to MannKind’s Cricket^® inhaler

DANBURY, Conn. and WESTLAKE VILLAGE, Calif., May 29, 2024 (GLOBE NEWSWIRE) — MannKind Corporation (Nasdaq: MNKD), a company focused on the development and commercialization of innovative inhaled therapeutic products and devices for patients with endocrine and orphan lung diseases, announced today that it has agreed to in-license iSPERSE^™ technology from Pulmatrix for certain indications in exchange for an out-license of MannKind’s Cricket^® inhaler to Pulmatrix for inhaled delivery of dihydroergotamine (DHE) for migraine treatment. The two companies also agreed that Pulmatrix will transfer its Bedford, Mass. R&D facility to MannKind, along with all leasehold improvements, laboratory equipment and other related personal property used in the laboratory in non-cash transaction.

“We are delighted to grow our Boston-area presence as we continue to progress our pipeline efforts, and in particular, our expanding orphan lung programs,” said Michael Castagna, PharmD, Chief Executive Officer of MannKind Corporation. “We have formulated two FDA-approved products utilizing our proven Technosphere^® dry powder technology, and this agreement affords us access to another option for future development opportunities.”

“Our Technosphere technology, which is a unique carrier-based, dry powder inhalation platform used in tandem with our proprietary inhaler, provides deep and effective penetration of lung tissue that is well suited for many active ingredients,” said Dr. Burkhard Blank, Executive Vice President, Research & Development and Chief Medical Officer of MannKind Corporation. “However, for some drug candidates, such as Clofazimine, that may require a significantly higher drug payload, the iSPERSE formulation technology may be better suited for developing viable powders.”

The royalty-free licensing structure will allow MannKind to have exclusive use of the iSPERSE technology for clofazimine, NTM, and insulin, and non-exclusive use for endocrine diseases and interstitial lung diseases (ILD) including idiopathic pulmonary fibrosis (IPF), progressive pulmonary fibrosis (PFF) and other related lung diseases. In exchange, Pulmatrix will receive a royalty-free, exclusive license to MannKind’s single-use Cricket inhalation device for inhaled delivery of DHE in any formulation and non-exclusive use for neurological diseases.

MannKind expects to consolidate its Boston presence by transitioning its Marlborough staff into the newly renovated, fully outfitted R&D facility in Bedford. To maintain continuity of iSPERSE platform knowledge, MannKind plans to hire some members of current Pulmatrix R&D staff.

The agreement is anticipated to close in July 2024.
