Aileron Therapeutics Q1 2024 Financial Results and Business Highlights

Aileron Therapeutics, Inc. reported promising results from the first cohort of its Phase 1b clinical trial of LTI-03 in patients with idiopathic pulmonary fibrosis (IPF). The company, based in Austin, Texas, and listed on NASDAQ, focuses on developing innovative treatments for orphan pulmonary and fibrosis conditions. The initial data showed positive trends in seven of the eight biomarkers evaluated, with three achieving statistical significance, indicating a potential improvement in lung function and disease reversal. Topline results from the high-dose cohort (5 mg BID) are anticipated in the third quarter of 2024.

In the first quarter of 2024, Aileron made significant advancements, particularly with LTI-03. Brian Windsor, Ph.D., the company's President and CEO, expressed optimism about the low-dose LTI-03's efficacy and safety, which supports its potential to treat IPF effectively.

During this period, the company also secured approximately $20 million through a direct offering of common stock and accompanying warrants in May 2024. This financial move is expected to support Aileron's operations into the second half of 2025, considering the current operational plan. Additionally, Brian Windsor was appointed as President and CEO, having previously served as COO and CEO of Lung Therapeutics, Inc., which Aileron acquired in October 2023.

The ongoing Phase 1b trial of LTI-03 showed that the drug, administered at a low dose twice daily to twelve IPF patients, resulted in a positive trend across seven biomarkers. Notably, the drug reduced the expression of profibrotic proteins and stimulated the production of solRAGE, a factor crucial for type I epithelial cell health. Importantly, LTI-03 was well-tolerated with no serious adverse events reported. The trial's next phase will evaluate the high-dose form of LTI-03, with results expected later in 2024.

Financially, Aileron reported a cash position of $12 million as of March 31, 2024, down from $17.3 million at the end of 2023. The reduction is partly due to increased R&D and G&A expenses following the acquisition of Lung Therapeutics. R&D expenses for Q1 2024 were $3.5 million, up from $1.8 million in the same period in 2023, driven by clinical trials, manufacturing, and regulatory activities related to Lung Therapeutics' programs. G&A expenses also rose to $3.7 million from $2.2 million, primarily due to higher professional fees and employee-related costs linked to the acquisition.

Overall, Aileron reported a net loss of $7.1 million for the first quarter of 2024, compared to $4.8 million in the same period in 2023. Despite the financial losses, the company remains focused on advancing its pipeline, particularly with the promising initial results from LTI-03.

Aileron Therapeutics continues to position itself as a key player in the biopharmaceutical industry, with a strong focus on addressing unmet medical needs in pulmonary and fibrosis indications. The upcoming results from the high-dose LTI-03 cohort are highly anticipated and could potentially solidify the drug's role in treating IPF.
