HAYWARD, Calif.,, Feb. 12, 2026 (GLOBE NEWSWIRE) -- Benitec Biopharma Inc. (NASDAQ:BNTC) ("Benitec" or the "Company"), a clinical-stage, gene therapy-focused, biotechnology company developing novel genetic medicines based on its proprietary "Silence and Replace" DNA-directed RNA interference ("ddRNAi") platform, today announced financial results for its second fiscal quarter ended December 31, 2025. The Company has filed its quarterly report on Form 10-Q with the U.S. Securities and Exchange Commission.

"We continue to be encouraged by the benign safety profile and the durability of efficacy demonstrated in our BB-301 clinical development program," said Jerel A. Banks, M.D., Ph.D., Executive Chairman and Chief Executive Officer of Benitec. "We look forward to engaging with the U.S. Food and Drug Administration (FDA) in mid-2026 to confirm the BB-301 pivotal study design and continuing to present interim clinical results at future medical conferences. I want to sincerely thank our investigators, our clinical advisors, and—most importantly—the patients and families who have made this progress possible."

The recent and upcoming key milestones related to the development of BB-301 for the treatment of Oculopharyngeal Muscular Dystrophy-related Dysphagia, are outlined below:

Responder Analysis for Study Completers

A Responder Analysis was developed to facilitate standardized evaluation of BB-301 efficacy for each Patient. The Responder Analysis consists of multiple discrete response categories that collectively assess the dysphagic symptom burden in patients with OPMD.
These response categories include:
- Patient-Reported Outcome: Patient-reported oral-pharyngeal dysphagia as assessed by the Sydney Swallow Questionnaire (SSQ) total score
- Videofluoroscopic Swallowing Study (VFSS) Assessments:
  - Pharyngeal constrictor muscle function as estimated by the Pharyngeal Area at Maximum Constriction (PhAMPC)
  - Swallowing efficiency as measured by NRRS_v and Total Pharyngeal Residue %(C2-4)²
  - Frequency of pathologic sequential swallows (SEQ)
- Functional Swallowing Capacity: Cold-Water Timed Drinking Test (CWDT)
The evaluation is completed as follows:
- Following completion of the 12-month post-treatment follow-up timepoint, each discrete response category is evaluated for each study Completer using prespecified statistical criteria
- Results of the statistical characterization of each response category are combined into a single scoring framework that facilitates the overall assessment of clinical benefit achieved by each Completer following treatment with BB-301
- A total Score of 5 is possible
- Responder status for each Completer will be assigned based on the achievement of statistical criteria for at least 2 out of 5 discrete response categories (≥40%)

Responder Analysis for Study Completers:

All four Cohort 1 Completers were formal responders to BB-301, demonstrating durable response to BB-301 at the conclusion of the 12-month statistical follow-up period.

Responder Analysis for Study Completers

24-Month Post-Treatment Follow-Up for Patient 1 of Cohort 1

At the 24-month post-BB-301 treatment follow-up timepoint, Patient 1 of Cohort 1 continued to demonstrate robust, disease-modifying outcomes. Patient 1 demonstrated deepening improvements in post-swallow pharyngeal residue as compared to the final pre-treatment timepoint and as compared to the 12-month post-treatment follow-up timepoint as assessed by VFSS. Patient 1 also experienced deepening improvements in total dysphagic symptom burden as assessed by the SSQ.

Enrollment into the BB-301 Phase 1b/2a Clinical Treatment Study is Ongoing:

The first Patient in Cohort 2 was safely treated with the higher-dose of BB-301 in 4Q of 2025 and an update on the interim clinical results of Cohort 2 is planned for mid-2026.

Corporate Updates:

The Company plans to engage with the FDA in mid-2026 to confirm the BB-301 pivotal study design. In November 2025, Fast Track Designation was granted for BB-301 following FDA review of positive interim clinical study results and the proprietary Responder Analysis planned for use in the BB-301 pivotal study. Previously, BB-301 has received Orphan Drug Designation from the EMA and the FDA.

About BB-301

BB-301 is a silence and replace-based genetic medicine currently under development by Benitec. BB-301 uses DNA-directed RNA interference (ddRNAi) to simultaneously silence the mutant gene and replace it with a functional gene, potentially providing a permanent solution with a single administration. This fundamental therapeutic approach to disease management is called "silence and replace." The silence and replace mechanism offers the potential to restore the normative physiology of diseased cells and tissues and to improve treatment outcomes for patients suffering from the chronic, and potentially fatal, effects of OPMD. BB-301 has been granted Orphan Drug Designation from the EMA and Orphan Drug and Fast Track Designations from the FDA.

About Benitec Biopharma, Inc.

Benitec Biopharma Inc. ("Benitec" or the "Company") is a clinical-stage biotechnology company focused on the advancement of novel genetic medicines with headquarters in Hayward, California. The proprietary "Silence and Replace" DNA-directed RNA interference platform combines RNA interference, or RNAi, with gene therapy to create medicines that simultaneously facilitate sustained silencing of disease-causing genes and concomitant delivery of wildtype replacement genes following a single administration of the therapeutic construct. The Company is developing Silence and Replace-based therapeutics for chronic and life-threatening human conditions including Oculopharyngeal Muscular Dystrophy (OPMD).
