Genenta Announces €20 million ($21.9M) Financing To Expand Pipeline As Brain Tumor Trial Is Showing Promising Survival Rates

MILAN and NEW YORK, March 19, 2025 (GLOBE NEWSWIRE) -- Genenta Science (NASDAQ:GNTA), a pioneer in immuno-oncology and a leader in cell-based therapeutics, today announced a €20 million ($21.9 million) financing through the issuance of a Mandatory Convertible Bond to ENEA Tech and Biomedical (ETB) to support the expansion of its pipeline by advancing Temferon in metastatic Renal Cell Cancer (mRCC). ETB is a leading private foundation, supervised by the Italian Ministry of Enterprises and Made in Italy, managing over €1,7 billion in assets under management through two funds. With deep expertise in the biomedical sector, ETB is an established authority in identifying and supporting high-potential biotech companies.

"ETB conducted a deep and thorough scientific and legal due diligence before committing to this investment. We spent several months in negotiations," said Pierluigi Paracchi, CEO of Genenta. "We believe the mandatory convertible bond terms are indicative of the potential long-term value of Genenta's shares. The bond will not result in immediate dilution to Genenta's shareholders, and is expected to provide the necessary capital to achieve key milestones in the Company's new mRCC trial. Conversion to equity is set for March 2028, followed by a two-year lock-up period. Naturally, the process will be accelerated in the event of a change of control of our Company. ETB is a trusted partner with strong financial backing, which will help ensure the financial stability required to advance the validation of the Temferon platform and our ability to pursue strategic collaborations."

The February data cutoff from the Phase 1/2a Glioblastoma Multiforme (GBM) uMGMT trial shows an increase in the percentage of patients surviving at two years, now reaching 29%, compared to 25% in October. Additionally, there is a marginal improvement in median overall survival, which now stands at 17 months. Historically reported data showed the overall survival of uMGMT patients undergoing standard of care to be approximately 14% at two years with a median overall survival of 13–15 months.

Notably, the Phase 1/2a trial in metastatic Renal Cell Carcinoma has recently begun enrolling patients, further strengthening the Company's clinical pipeline for Temferon.

Prof. Luigi Naldini, Co-founder of Genenta, added: "We are continuing to demonstrate at pre-clinical and clinical levels Temferon's ability to reprogram the tumor microenvironment, which in turn induces cell-mediated immune responses, as suggested by Genenta's ongoing GBM trial and which will be under testing in the Company's mRCC trial."

ETB Mandatory Convertible Bond Investment Terms:

• Total Bond: €20 million ($21.9M), subscribed by ETB;
• Maturity: three years, with mandatory conversion at maturity (March 2028);  
• Lock-up: two years following conversion (March 2030);

  • Second Tranche: €12.5 million ($13.7M), conditional upon achieving safety and tolerability in the ongoing Phase 1/2a trial for mRCC, among other conditions.
• ETB equity in Genenta will be capped at 29%.
• The maximum conversion price is $17.64 per share based on an Independent Evaluation conducted by ETB's Advisor on Genenta.

About Genenta

Genenta (NASDAQ:GNTA) is a clinical stage immuno-oncology company developing a proprietary hematopoietic stem cells therapy for the treatment of a variety of solid tumor cancers. Genenta first in class product candidate is Temferon™, which is designed to allow the expression of immune-therapeutic payloads within the tumor microenvironment by bone marrow derived myeloid cells and enable a durable and targeted response. Genenta has completed the Phase 1 trial for newly diagnosed Glioblastoma Multiforme patients with an unmethylated MGMT gene promoter, which suggests the potential reprogramming of the tumor microenvironment and inhibiting of myeloid induced tolerance, while allowing the induction of T cell responses, potentially breaking immune tolerance. Genenta has initiated in Q4 2024 a Phase 1/2a metastatic Renal Cell Carcinoma study that will also include a combination with immune checkpoint inhibitors. Genenta's treatments are designed as one-time monotherapies, but with the additional potential, when used in combination, to significantly enhance the efficacy of other approved therapeutics.
