Detalimogene Voraplasmid

BOSTON & MONTREAL--( BUSINESS WIRE )--enGene Holdings Inc. (Nasdaq: ENGN, or “enGene” or the “Company”), a clinical-stage genetic medicines company whose non-viral lead investigational product detalimogene voraplasmid, (also known as detalimogene, and previously EG-70), is in an ongoing pivotal study in patients with high-risk, Bacillus Calmette-Guérin (BCG)-unresponsive, non-muscle invasive bladder cancer (NMIBC) with carcinoma in situ (CIS), announced its financial results for the full year ended October 31, 2024 and provided a business update. “ Having demonstrated a 71% anytime complete response rate in the preliminary data from the LEGEND study’s pivotal cohort of BCG-unresponsive NMIBC patients, initiated three additional NMIBC patient cohorts, and raised an additional $60 million in funding, enGene is in a strong clinical and financial position as we close the year,” said Ron Cooper, Chief Executive Officer of enGene. “ With trial recruitment open across all cohorts, the profile of detalimogene continues to become clearer and stronger and, with the protocol enhancements now in place, we look forward to sharing LEGEND study updates across all cohorts expected in the second half of 2025.” Recent Strategic Corporate Updates Release of preliminary data from LEGEND’s pivotal cohort: In September 2024, the Company announced preliminary data from 21 patients assessed at three months, including 17 patients who were also assessed at six months, in the ongoing pivotal cohort of the LEGEND study. The Complete Response (CR) rate at any time was 71%, the CR rate at three months was 67% and the CR rate at six months was 47%. Detalimogene was generally well-tolerated by patients and no patients discontinued due to treatment-related adverse events. LEGEND study protocol amendment: In addition to reporting preliminary clinical data from LEGEND’s pivotal cohort, the Company has implemented protocol changes that affect how disease is managed throughout the trial as well as the criteria for study discontinuation. The Company believes the revised LEGEND protocol better aligns with current treatment standards and real-world practice. LEGEND study now enrolling across all four cohorts: enGene initiated recruitment across three additional cohorts of NMIBC patients, including Cohort 2a and 2b (i.e., NMIBC patients with CIS who are naïve to treatment with BCG and NMIBC patients with CIS who have been exposed to BCG, but have not received adequate BCG treatment), and Cohort 3 (BCG-unresponsive high-risk NMIBC patients with papillary-only disease). LEGEND study now includes maintenance dosing: The above-mentioned amendment to the LEGEND protocol also allows patients from any cohort who are in complete response at 12 months to continue receiving detalimogene on a dose-reduced maintenance schedule throughout their second year of treatment. At the end of year two, patients may optionally elect to remain on maintenance therapy for another year, for a total of three years of therapy. Maintenance treatment will consist of two instillations of detalimogene per three-month cycle, administered at week 1 and at week 2 of each cycle. The Company believes this could provide further evidence of the long-term benefit of detalimogene, with the dose-reduced maintenance regimen lessening the burden of frequent urology visits for instillations. Inclusion in the Society of Urologic Oncology’s Clinical Trial Consortium (SUO CTC): The LEGEND study was selected for inclusion in the SUO-CTC, a U.S. and Canadian-based organization with over 250 trial sites dedicated to the successful enrollment and conduct of clinical trials for their patients with urologic cancers. Key executive hires and management appointments: In October 2024, the Company announced the appointment of Joan Connolly, a seasoned technical operations leader with more than 30 years’ experience, as Chief Technology Officer (CTO) and member of the corporate leadership team. enGene Co-Founder and former CTO, Anthony Cheung, Ph.D., transitioned to the role of Chief Scientific Officer, while Alex Nichols, Ph.D., previously the Chief Operating Officer, was appointed Chief Strategy and Operations Officer. Fourth Quarter 2024 Financial Results As of October 31, 2024, cash, cash equivalents and marketable securities were $297.9 million. The Company expects that its existing cash and cash equivalents will fund operating expenses, debt obligations and capital expenditures into 2027. Full Year Financial Results ended October 31, 2024 Total operating expenses were $62.3 million for the full year ended October 31, 2024, compared to $26.1 million for 2023. Research and development expenses increased by $21.9 million, mainly due to increasing manufacturing and clinical costs related to our LEGEND study and headcount costs. General and administrative expenses increased by $14.4 million, primarily driven by headcount costs and professional fees and other expenses as the Company scales its general and administrative function to support the operation of a public company. For the full year ended October 31, 2024, net loss attributable to common shareholders was approximately $55.1 million, or $1.46 per share, compared to approximately $104.7 million, or $151.22 per share, for the full year 2023. The decrease in net loss is mainly attributed to other expenses incurred in 2023 related to convertible debentures and warrants, partially offset by the increase in operating expenses during 2024.
