Forbion European Acquisition 8-KEntry into a Material Definitive Agreement

Exhibit 99.1

enGene (Nasdaq: ENGN) Launched as Publicly Traded Genetic Medicines Company

Business combination transaction completed with Forbion European Acquisition Corp.

Clinical stage biotechnology company with EG-70 lead program in pivotal clinical study targeting BCG-unresponsive non-muscle invasive bladder cancer (NMIBC)

$138M in gross proceeds from transaction to support advancement of EG-70 clinical program, which is currently enrolling patients, and continued pipeline expansion in additional therapeutic areas

Boston, Mass. and Montreal, Canada, November 1, 2023 — enGene Holdings Inc. (“enGene” or the “Company,” Nasdaq: ENGN) today announced the completion of the previously announced business combination between enGene Inc., a clinical-stage genetic medicines company whose lead program is in a pivotal study for BCG-unresponsive non-muscle invasive bladder cancer (NMIBC), and Forbion European Acquisition Corp. (“FEAC,” Nasdaq: FRBN), a special purpose acquisition company. The Company also announced a concurrent transaction financing. As a result of the business combination, enGene Holdings Inc. became a publicly traded company, with enGene Inc., its subsidiary, continuing existing business operations. enGene will commence trading under the symbol “ENGN” on November 1, 2023 on Nasdaq. Gross proceeds from this transaction totaled approximately $138.0 million, which included funds held in the FEAC trust account net of redemptions, and the concurrent, oversubscribed private investment in public equity and other private (PIPE) financing. The enGene management team, headed by Chief Executive Officer, Jason Hanson, will lead the combined company.

“We are thrilled to begin this new phase of enGene’s journey as a public company,” said Jason Hanson, chief executive officer of enGene. “This transaction will support our continued mission to expand genetic medicine into the mainstream of clinical practice. Our lead program, EG-70 (detalimogene voraplasmid), is in an ongoing pivotal study in patients with BCG-unresponsive non-muscle-invasive bladder cancer with carcinoma in situ, and with an additional arm enrolling BCG-naïve patients. EG-70 aims to address the high disease burden faced by patients as well as the clinical and practical limitations of current therapies and those in late-stage development. We are optimistic about the therapeutic activity observed to date and look forward to the interim results from our pivotal study, expected in mid-2024. With our lead program and our proprietary technologies, we are committed to serving patients and clinical communities by working to develop safe, effective, fit-for-purpose medicines that seamlessly integrate into medical practice.”

“We are excited about the next phase of enGene and the continued development of EG-70 as a potential best-in-class therapy for non-muscle invasive bladder cancer,” said Jasper Bos, Ph.D., chief executive officer of FEAC. “Based on the available clinical data, we believe EG-70 is likely to show meaningful monotherapy efficacy in this challenging indication. Furthermore, EG-70 does not require the accompanying use of an indwelling device or co-administration with either BCG or an anti-PD-1/anti-PD-L1 agent. We believe that EG-70 has the potential to result in a highly effective and patient-friendly therapy that is well suited for the community oncologists at the front lines of NMIBC patient care.”

About the Transaction

As previously announced, on May 16, 2023, enGene Inc., now a wholly-owned subsidiary of the Company, entered into a definitive business combination agreement with FEAC, a special purpose acquisition company (SPAC) sponsored by Forbion group (“Forbion”), a life sciences specialist venture fund manager with headquarters in Naarden, the Netherlands, and offices in Munich, Germany, and Singapore.

The business combination was unanimously approved by FEAC’s board of directors and was approved by FEAC’s shareholders on October 24, 2023. The boards of directors of enGene and enGene Inc. also unanimously approved the business combination, and enGene Inc.’s shareholders voted in favor of the business combination on October 24, 2023.

As a result of the business combination (the “Business Combination”) and an associated private financing, enGene received proceeds of approximately $138.0 million, prior to transaction expenses, which includes cash proceeds of approximately $25.0 million from FEAC trust account (net of redemptions) and $113.0 million from private investors including, among others, BVF Partners, Omega Funds, Cowen Healthcare Investments, Investissement Québec, Vivo Capital, Northleaf Capital Partners and CTI Life Sciences Fund III, along with existing enGene investors Forbion Ventures III, Fonds de solidarité FTQ and Lumira Ventures. Net proceeds are expected to be used to fund the clinical development of EG-70, as well as support the development of pipeline programs in gynecological/genitourinary (GYN/GU) malignancies and respiratory diseases.

About enGene

enGene is a clinical-stage biotechnology company mainstreaming genetic medicines through the delivery of therapeutics to mucosal tissues and other organs, with the goal of creating new ways to address diseases with high clinical needs. enGene’s lead program is EG-70 for patients with non-muscle invasive bladder cancer (NMIBC) with carcinoma in situ (Cis) who are unresponsive or naïve to treatment with Bacillus Calmette-Guérin (BCG)—a disease with a high clinical burden. EG-70 is being evaluated in an ongoing Phase 2 pivotal study. EG-70 was developed using enGene’s proprietary Dually Derivatized Oligochitosan (DDX) platform, which enables penetration of mucosal tissues and delivery of a wide range of sizes and types of cargo, including DNA and various forms of RNA.

About enGene’s EG-70 Program

enGene’s lead product candidate, EG-70 (detalimogene voraplasmid), is a non-viral immunotherapy comprised of three gene cargos delivered via our proprietary Dually Derivatized Oligochitosan (DDX) platform. EG-70 is being evaluated as a monotherapy in a pivotal study to treat NMIBC patients with carcinoma-in-situ (Cis) who are unresponsive to treatment with Bacillus Calmette-Guérin (BCG). It is also being studied as a monotherapy to treat NMIBC patients with Cis who are naïve to BCG. EG-70 is applied by intravesical administration and encodes two RIG-I agonists intended to stimulate the innate immune system and IL-12 to stimulate the adaptive immune system. With cargoes selected to stimulate both arms of the immune system, EG-70 is designed to generate a strong local immune reaction in proximity to tumors, enabling the immune system to reduce or clear the tumor and develop memory to resist recurrence without significant systemic toxicities.

About enGene’s Dually Derivatized Oligochitosan (DDX) platform

enGene’s DDX platform is a breakthrough that enables the delivery of therapeutics to mucosal tissues and other organs, with the goal of creating new ways to address diseases with high unmet clinical needs. DDX is designed to enable a carrier to penetrate mucosal tissue and deliver a wide range of sizes and types of cargo, including DNA and various forms of RNA, by turning mucosal cells into therapeutic production “factories” that generate proteins and RNAs for a desired local effect. This platform is designed to support localized treatment specifically to the target site without the immunogenicity and systemic effects typical of viral vector-based genetic medicines, with the goal of expanding gene therapy to multiple clinical settings. enGene’s DDX platform is well-positioned for deployment and partnership across a number of therapeutic areas and organ systems, including the bladder, genitourinary cancers, and the lung.
