With a focus on leveraging its proprietary induced pluripotent stem cell (iPSC) technology, Eterna is engineering a pipeline of cell-based therapies designed to harness the power of the immune system and deliver transformative results.

Business Overview and History

Eterna Therapeutics was founded in 2018 with the vision of improving the lives of patients through the development of accessible, effective, and safe cellular therapies. The company's origins trace back to the acquisition of IRX Therapeutics in 2018, which resulted in Eterna recording $2 million in goodwill. This acquisition provided Eterna with a solid foundation in immunotherapy research and development.

In 2021, Eterna made several strategic moves to strengthen its position in the cell therapy space. The company acquired Novellus Inc. and entered into a license agreement with Factor Limited. However, these strategic initiatives came at a significant financial cost. Eterna reported a substantial net loss of $122.5 million for the year, largely due to $95 million in unusual items, including a $79.6 million charge for other special charges.

The following year, 2022, brought continued financial challenges for Eterna. The company reported a net loss of $24.6 million, with operating expenses remaining high at $26.9 million. This included $10.4 million in research and development costs and $16.6 million in general and administrative expenses. Additionally, Eterna recorded $6.3 million in special income charges during this period.

Despite these financial hurdles, Eterna successfully raised $19.7 million in 2022 through the issuance of common stock, providing much-needed capital to support its ongoing research and development efforts. The company ended 2022 with $11.5 million in cash and cash equivalents on its balance sheet, bolstering its financial position as it continued to advance its cell therapy pipeline.

Eterna's lead product candidate, ERNA-101, is an allogeneic iMSC therapy designed to treat advanced solid tumors, including triple-negative breast cancer and platinum-resistant, tp53-mutant ovarian cancer. Preclinical studies have demonstrated ERNA-101's ability to induce and modulate antitumor immunity, with the potential to overcome the immunosuppressive tumor microenvironment and enhance the activity of cancer-fighting T cells.

In 2024, Eterna further strengthened its pipeline by entering into an exclusive license and collaboration agreement with Factor Bioscience. This strategic partnership granted Eterna exclusive rights to develop and market iPSC-based cell therapies utilizing Factor's proprietary cell reprogramming and gene-editing technologies. This collaboration has accelerated Eterna's efforts to advance its cell therapy candidates for oncology, autoimmune disorders, and rare diseases.

Financial Overview

Eterna Therapeutics has been diligently managing its financial resources to support its research and development activities. For the fiscal year ending December 31, 2023, Eterna reported annual revenue of $68,000 and a net loss of $21.7 million. The company's annual operating cash flow was negative $20.4 million, with a free cash flow of negative $20.4 million for the same period.

In the third quarter of 2024, Eterna generated revenue of $487,000 and reported a net loss of $26.6 million. The company's year-over-year revenue growth was an impressive 853%, primarily due to the acceleration of deferred revenue related to the Lineage Agreement that was assigned to Factor Bioscience.

Liquidity

Eterna's balance sheet reflects the challenges faced by a preclinical-stage biotech company.
