• LTI-03 has shown promise in preclinical studies, demonstrating the ability to protect lung epithelial cells and reduce pro-fibrotic signaling.
• LTI-01 has demonstrated preliminary signs of efficacy in LPE patients, with reductions in pleural opacity and declines in pleural infection indicators.
• The company has secured Orphan Drug Designation for LTI-03 in the U.S. for IPF and for LTI-01 in the U.S. and EU for empyema.
• The company has a regional licensing deal with Taiho for the rights to develop and commercialize LTI-01 in Japan, which includes an upfront payment of $5.0 million and potential future milestone payments.

Negatives

• The company has a limited operating history and no products approved for commercial sale.

Future Outlook

The company expects to report top-line data from the Phase 1b clinical trial of LTI-03 in the third quarter of 2024 and plans to investigate LTI-01 in an additional Phase 2 dose-ranging, placebo-controlled clinical trial.

Management Comments

• The company shifted its operating disease focus to advancing a pipeline of first-in-class medicines to address significant unmet medical needs in orphan pulmonary and fibrosis indications.

Industry Context

The biotechnology and biopharmaceutical industries are characterized by rapidly advancing technologies, strong competition, and an emphasis on proprietary products. Aileron faces competition from larger pharmaceutical companies with greater resources, as well as smaller specialty biotechnology and biopharmaceutical companies, academic research institutions, and governmental agencies.

Comparison to Industry Standards

• Aileron's approach to drug research and development in the area of fibrotic diseases, with a focus on Cav1-related peptides, is unique compared to most other existing or investigational therapies.
• The company is competing with larger companies such as AbbVie Inc., Boehringer Ingelheim GmbH, Bristol Myers Squibb Company, Gilead Sciences, Inc., Roche Holding AG, Novartis AG, and Pliant Therapeutics, Inc. in the fibrosis space.
• In the IPF market, Aileron will compete with marketed products such as Esbriet (Roche) and Ofev (Boehringer Ingelheim), as well as other companies developing product candidates in IPF.
• In the LPE market, Aileron is not aware of any other pharmaceutical or biotechnology company developing drug therapies for the treatment of LPE, but will compete with off-label use of tPA and DNase.

Management Changes

Corporate Governance

Related Party Transactions

• The company entered into a Stock and Warrant Purchase Agreement with a group of accredited investors led by Bio Partners, the majority stockholder of Lung prior to the closing of the Lung Acquisition.

• Suppliers and creditors may face increased risk of non-payment due to the company's financial instability.

Next Steps

• The company will continue recruiting patients for the Phase 1b clinical trial of LTI-03 in IPF.
• The company expects to report top-line data from the Phase 1b clinical trial of LTI-03 in the third quarter of 2024.
• The company plans to investigate LTI-01 in an additional Phase 2 dose-ranging, placebo-controlled clinical trial.
