Benitec Biopharma Releases First Quarter 2025 Financial Results and Provides Operational Update

-Positive 270-day Interim Clinical Study Data for the First Subject and Positive 180-day Interim Clinical Study Data for the Second Subject Treated with the Low-Dose of BB-301 in the Phase 1b/2a Clinical Treatment Study Reported in October as a Late-Breaking Oral Presentation at the 29^th Annual Congress of the World Muscle Society-

-Third Subject Safely Treated with the Low-Dose of BB-301 in October 2024, and Fourth Subject Expected to Receive Treatment with the Low-Dose of BB-301 in December 2024

HAYWARD, Calif., November 14, 2024 (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 first fiscal quarter ended September 30, 2024. The Company has filed its quarterly report on Form 10-Q for the quarter ended September 30, 2024 with the U.S. Securities and Exchange Commission (SEC).

"We recently announced the 270-day interim clinical study results for the first Subject and the 180-day interim clinical study results for the second Subject enrolled into the low-dose cohort of the BB-301 Phase 1b/2a Clinical Treatment Study. We continue to be extremely grateful for the strong support of the Subjects and their families and for their continued participation in the BB-301 clinical development program. We were highly encouraged by the significant, clinically meaningful improvements observed for both Subjects treated at the low-dose of BB-301, with Subject 1 experiencing durable improvements in core dysphagic symptoms of 35% to 40%, and Subject 2 achieving a clinically normal swallowing profile based on the results of the Sydney Swallow Questionnaire," said Jerel A. Banks, M.D., Ph.D., Executive Chairman and Chief Executive Officer of Benitec. "The third Subject was treated with the low-dose of BB-301 in October 2024, and we anticipate the treatment of the fourth Subject in December 2024. We remain optimistic about the potential for continued benefit in Subjects enrolled in the ongoing study and, including funds from recent exercises of shareholder-held warrants, Benitec is well-funded to advance the BB-301 clinical development program. We look forward to enrolling additional Subjects at the next, higher dose of BB-301, in 2025."

Operational Updates

The key milestones related to the development of BB-301 for the treatment of Oculopharyngeal Muscular Dystrophy (OPMD)-related Dysphagia, are outlined below:

Summary of Interim Clinical Study Results for Subject 1 and Subject 2:

•

At the lowest-dose of gene therapy BB-301 (1.2e13 vg/subject), there were no Significant Adverse Events observed.

•

Dysphagic symptoms at baseline for Subject 1 (7-years post diagnosis) were more severe than those of Subject 2 (6-years post diagnosis) as assessed by pre-dose Sydney Swallow Questionnaire (SSQ) and Total Pharyngeal Residue (TPR) results, but both subjects experienced significant clinical benefit per the post-dose SSQ scores and TPR results.

•

The SSQ Total Scores and SSQ Sub-Scores correlate strongly with the Videofluoroscopic Swallowing Study (VFSS) TPR results.

•

Subject 1 experienced clinically meaningful improvements in post-dose SSQ Total Score and SSQ Sub-Scores at Day 270 driven by corresponding reductions in VFSS TPR values.

•

Subject 2 experienced clinically meaningful improvements in post-dose SSQ Total Score and SSQ Sub-Scores at Day 180, with an SSQ Total Score representative of a normal swallowing profile, driven by a corresponding reduction in the frequency of pathologic low-volume sequential swallows.

•

These data represent the first reported successful improvements in swallowing function following the use of a novel gene therapy for OPMD.

Subjects Enrolled in the BB-301 Clinical Development Program are Impacted by Two Discrete Drivers of Dysphagic Symptoms:

•

Excessive accumulation of pharyngeal residue post-swallow (i.e., inefficiency of swallowing) represents one key driver of dysphagic symptoms.

•

Pathologic low-volume sequential swallows represent a second key driver of dysphagic symptoms.

•

Pathologic low-volume sequential swallows are characterized on videofluoroscopic swallowing study examination as rapid contractions of the pharyngeal muscles without full restoration of the resting pharyngeal diameter between contractions.

•

This pharyngeal contraction pattern is aberrant and is not observed in healthy subjects during the consumption of low-volumes of thin liquids (e.g., ≤15 milliliters water).

Interim Clinical Study Results for Subject 1 (270-Days Post Treatment with BB-301):

•

Global inefficiency of swallowing for solid food, thin liquid, and thick liquids drives dysphagia for Subject 1.

•

Subject 1 displayed continued clinically meaningful reductions (i.e., improvements) in SSQ Total Score (35% reduction) and SSQ Sub-Scores (42% reduction for Thin Liquid, 16% reduction for Solid Food, and 22% reduction for Thick Liquids). Subject 1 displayed correspondingly significant reductions (i.e., improvements) in VFSS TPR (33% reduction for Thin Liquid, 18% reduction for Solid Food, and 30% reduction for Thick Liquids) following the administration of the low-dose of BB-301 as compared to the average values recorded for Subject 1 during the pre-dose period.

Interim Clinical Study Results for Subject 2 (180-Days Post Treatment with BB-301):

•

Pathologic low-volume sequential swallowing for thin liquid drives dysphagia for Subject 2. Pathologic low-volume sequential swallows are experienced by the Subject as multiple swallows and are detected during VFSS as a continuous series of rapid contractions of the pharyngeal muscles without full restoration of the resting pharyngeal diameter between contractions. The pathologic pattern of contractions interrupts the discrete peristaltic contractions typically observed during swallows of low volumes of thin liquids (e.g., ≤15 milliliters water), during which the resting diameter of the pharynx is fully restored between successive swallows.

•

Subject 2 displayed clinically meaningful reductions (i.e., improvements) in SSQ Total Score (89% reduction) and the SSQ Sub-Score for the necessity of repeat swallows during consumption (84% reduction) as compared to the average values recorded for Subject 2 during the pre-dose period. The average post-dose SSQ Total Score of 82 is representative of a clinically normal swallowing profile for Subject 2. Subject 2 displayed correspondingly significant reductions (i.e., improvements) in the post-dose frequency of pathologic low-volume sequential swallows as evaluated by VFSS (92% reduction) following the administration of the low-dose of BB-301 as compared to the pre-dose values recorded for Subject 2.

Both Subjects were blinded to their SSQ Total Scores and VFSS TPR assessment results, and the Central Reader for the VFSS assessments was blinded to the SSQ Total Scores and SSQ Sub-Scores for each Subject.

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

•

The third Subject was safely treated with the low-dose of BB-301 in October 2024, and the fourth Subject is anticipated to receive the low-dose of BB-301 in December 2024.

Adverse Events:

•

No Serious Adverse Events have been observed for the three Subjects treated with the low-dose of BB-301.

Corporate Updates:

•

On October 12th the Principal Investigator of the BB-301 Phase 1b/2a Clinical Treatment Study shared updated interim results for two Subjects treated in the Phase 1b/2a Open-label, Dose Escalation Study of BB-301 in a late-breaking oral presentation at the 29th Annual Congress of the World Muscle Society, in Prague, Czech Republic.

•

The Company held a webcast discussing the interim clinical study results on October 14th (the replay of this event is available here).

About BB-301

BB-301 is a novel, modified AAV9 capsid expressing a unique, single bifunctional construct promoting co-expression of both codon-optimized Poly-A Binding Protein Nuclear-1 (PABPN1) and two small inhibitory RNAs (siRNAs) against mutant PABPN1 (the causative gene for OPMD). The two siRNAs are modeled into microRNA backbones to silence expression of faulty mutant PABPN1, while allowing expression of the codon-optimized PABPN1 to replace the mutant with a functional version of the protein. We believe the silence and replace mechanism of BB-301 is uniquely positioned for the treatment of OPMD by halting mutant expression while providing a functional replacement protein.
