HAYWARD, Calif., Sept. 26, 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 full year ended June 30, 2024. The Company has filed its annual report on Form 10-K with the U.S. Securities and Exchange Commission.

"The 90-day and 180-day interim clinical study results for the first subject enrolled into the low-dose cohort of the BB-301 Phase 1b/2a Clinical Treatment Study demonstrated clinically meaningful improvements in the central study endpoints, with significant improvements noted across the radiographic assessments of swallowing efficiency and corresponding improvements observed for the key dysphagia-focused subject-reported outcome measure," said Jerel A. Banks, M.D., Ph.D., Executive Chairman and Chief Executive Officer of Benitec. "Additional clinical data for the BB-301 Phase 1b/2a Clinical Treatment Study were accepted for oral presentation during the Late Breaking session of the 29^th Annual Congress of the World Muscle Society on October 12, 2024. The recent financing comfortably positions Benitec to advance the BB-301 clinical development program through the end of 2025."

Operational Updates

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

Interim BB-301 Phase 1b/2a Clinical Treatment Study Results for Subject 1:

Background Information Regarding the Key Clinical Assessments and Radiographic Outcome Measures Employed in the BB-301 Phase 1b/2a:

• Total Pharyngeal Residue (TPR) comprises the total amount of solid food or liquid material remaining in the pharynx after the completion of the first swallow of the bolus. TPR is objectively characterized via the completion of videofluoroscopic swallowing studies (VFSS) which evaluate the complete swallowing process for each subject in the context of four food types (i.e., Thin Liquid, Moderately Thick Liquid, Extremely Thick Liquid, and Solid Food). The consistency of Thin Liquid is similar to that of water. The consistency of Moderately Thick Liquid is similar to that of a smoothie. The consistency of Extremely Thick Liquid is similar to that of yogurt or pudding.
  
  
  
  
• The Sydney Swallow Questionnaire (SSQ) is a paper-based questionnaire assessing subjective symptoms of oral-pharyngeal dysphagia, and the questionnaire is completed independently by the study subject at each clinical study visit. The 17-item questionnaire measures the symptomatic severity of oral-pharyngeal dysphagia.
  
  

90-Day Post-Dose Interim Clinical Study Results:

• At the 90-day post-dose assessment following the administration of the low-dose of BB-301, Subject 1 demonstrated improvements in key VFSS assessments which correlated with the observation of similar levels of improvement in the SSQ as compared to the pre-dose average values recorded for Subject 1 during the OPMD Natural History Study, indicating an improvement in swallowing function as reported by Subject 1.
  
  

180-Day Post-Dose Interim Clinical Study Results:

• The post-dose average values for TPR remained meaningfully reduced (i.e., smaller amounts of solid food and liquid material remained in the pharynx after the completion of the first swallow) at the 180-day post-dose assessment following the administration of the low-dose of gene therapy BB-301 as compared to the pre-dose average values recorded for Subject 1 during the OPMD Natural History Study.
  
  
  
  
• The Total Score recorded for the Subject-Reported SSQ also demonstrated continued reductions in the Subject's dysphagic symptoms (i.e., improvements in the Subject's ability to swallow) at the 180-day post-dose timepoint, with the Total SSQ Score continuing to decline and remaining meaningfully reduced as compared to the pre-dose average value recorded for Subject 1 during the OPMD Natural History Study, indicating a greater improvement in swallowing function as reported by Subject 1.
  
  
  
  
• Key Opinion Leaders (KOLs) participating in the recent BB-301 Research and Development Day webcast (April 2024) highlighted VFSS assessments of TPR and the Subject-Reported Outcome SSQ Total Score as the central markers of value for the long-term evaluation of clinically meaningful improvement in subjects diagnosed with OPMD.
  
  

Continued Enrollment for the BB-301 Phase 1b/2a Clinical Treatment Study:

• The second subject received the Low-Dose of BB-301 in February 2024, and the third subject is expected to receive the low-dose of BB-301 in calendar quarter four of 2024.
  
  

Safety and Tolerability:

• Regarding the BB-301 safety profile observed to date, transient Grade 2 Gastroesophageal Reflux Disease or "GERD" (i.e., "acid reflux" or "heartburn") has been reported previously in April 2024 at the time of the Research and Development Day webcast. No Serious Adverse Events (SAEs) have been observed for the two subjects that have received the low-dose of BB-301.
  
  

Corporate Updates:

• On April 18^th the Company announced an oversubscribed $40.0 million private investment in public equity (PIPE) financing. The closing of the PIPE occurred on April 22, 2024.
  
  
  
  
• On July 1^st the company announced the appointment of Kishen Mehta to the board of directors (BOD) of the Company, effective June 26, 2024. Mr. Mehta's appointment follows the $40.0 million PIPE financing announced on April 18^th, led by long-term investor Suvretta Capital, where he serves as portfolio manager.
  
  
  
  
• On September 23^rd Jerel A. Banks, M.D., Ph.D. participated in the OPMD Awareness Day Webinar organized by the OPMD Association. A replay of the event can be found here.
  
  
  
  
• On October 12^th the Principal Investigator of the BB-301 Phase 1b/2a Clinical Treatment Study will make an oral presentation of a Late Breaking Abstract entitled "Interim Clinical Data Summary: A Phase 1b/2a Open-label, Dose Escalation Study to Evaluate the Safety and Clinical Activity of Intramuscular Doses of an AAV9-based gene therapy (BB-301) Administered to Subjects with Oculopharyngeal Muscular Dystrophy (OPMD) with Dysphagia" at the 29th Annual Congress of the World Muscle Society.

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.
