Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
You should read the following discussion and analysis of financial condition and operating results together with our consolidated financial statements and the related notes and other financial information included elsewhere in this document.
Overview
We endeavor to become the leader in discovery, development, and commercialization of therapeutic agents capable of addressing significant unmet medical need via the application of the silence and replace approach to the treatment of genetic disorders.
Benitec Biopharma Inc. (“Benitec” or the “Company” or in the third person, “we” or “our”) is a development-stage biotechnology company focused on the advancement of novel genetic medicines with headquarters in Hayward, California. The proprietary platform, called DNA-directed RNA interference, or ddRNAi, combines RNA interference, or RNAi, with gene therapy to create medicines that facilitate sustained silencing of disease- causing genes following a single administration. The Company is developing a ddRNAi-based therapeutic (BB-301) for the treatment of Oculopharyngeal Muscular Dystrophy (OPMD), a chronic, life-threatening genetic disorder.
BB-301 is a ddRNAi-based genetic medicine currently under development by Benitec. BB-301 is an AAV-based gene therapy designed to simultaneously silence the expression of the mutant, disease-causing gene (to slow, or halt, the biological mechanisms underlying disease progression in OPMD) and replace the mutant gene with a wild type gene (to drive restoration of function in diseased cells). 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 in the United States and the European Union.
The targeted gene silencing effects of RNAi, in conjunction with the durable transgene expression achievable via the use of modified viral vectors, imbues the silence and replace approach with the potential to produce long-term silencing of disease-causing genes along with simultaneous replacement of wild type gene function following a single administration of the proprietary genetic medicine. We believe that this novel mechanistic profile of the current and future investigational agents developed by Benitec could facilitate the achievement of robust and durable clinical activity while greatly reducing the frequency of drug administration traditionally expected for medicines employed for the management of chronic diseases.
Additionally, the achievement of long-term gene silencing and gene replacement may significantly reduce the risk of patient non-compliance during the course of medical management of potentially fatal clinical disorders.
COVID-19
COVID-19 has been declared a pandemic by the World Health Organization and has spread to nearly every country, including Australia and the United States. The impact of this pandemic has been, and will likely continue to be, extensive in many aspects of society, which has resulted in, and will likely continue to result in, significant disruptions to businesses and capital markets around the world. The extent to which the coronavirus impacts us will depend on future developments, which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity of the coronavirus and its variants, and the actions to contain the coronavirus or treat its impact, including the effectiveness and adoption of vaccines for the virus, among others.
Certain elements of our research and development efforts are conducted globally, including the ongoing development of our silence and replace therapeutic for the treatment of Oculopharyngeal Muscular Dystrophy (OPMD), and will be dependent upon our ability to complete preclinical studies and initiate clinical studies despite the ongoing COVID-19 pandemic.
As we endeavor to complete our development programs, including the ongoing Toxicology and Biodistribution study for BB-301, we are in close contact with our principal investigators, contract research organizations, and preclinical trial sites, which are primarily located in France, and are assessing the impact of COVID-19 on our studies and the expected development timelines and costs on an ongoing basis. In light of developments relating to the COVID-19 global pandemic since the beginning of the outbreak, the focus of healthcare providers and hospitals on fighting the virus, and consistent with the FDA’s industry guidance for conducting clinical trials, we have experienced delays to the original timeline regarding the initiation and anticipated completion of the ongoing BB-301 Clinical Trial Application (CTA)-enabling and Investigational New Drug Application (IND)-enabling development work. The initiation of the BB-301 Pilot Dosing Study in Beagle dogs, which represents a key component of the CTA-enabling and IND-enabling work, was delayed by several months, however, the study has been completed without incident. The acquisition of chemical reagents, biological reagents and laboratory supplies which are essential for the conduct of basic laboratory research, the conduct of nonclinical studies and the
15
completion of GMP manufacturing of BB-301, has also become challenging due to the disruption of global supply chains inherent to the production of these materials. We will continue to evaluate the impact of the COVID-19 pandemic on our business and we expect to reevaluate the timing of our anticipated preclinical and clinical milestones as we learn more and the impact of COVID-19 on our industry becomes clearer.
We have also implemented a halt of non-essential business travel and a rotation system whereby staff work from home and attend the laboratory on designated days which may result in a reduction of laboratory work. As we transition our employees back to our premises, there is a risk that COVID-19 infections occur at our offices or laboratory facilities and significantly affect our operations. Additionally, if any of our critical vendors are impacted, our business could be affected if we become unable to procure essential equipment in a timely manner or obtain supplies or services in adequate quantities and at acceptable prices.
Public Equity Offering
On September 15, 2022, we closed an underwritten public offering in which we issued and sold (i) 17,637,843 shares of the Company’s common stock, (ii) 12,171,628 pre-funded warrants, with each pre-funded warrant immediately exercisable for one share of common stock at an exercise price of $0.0001 per share until exercised in full and (iii) 29,809,471 common warrants, with each common warrant accompanying each issued share of common stock and/or pre-funded warrant and exercisable for one share of common stock at an exercise price of $0.66 per share (the “September 2022 Capital Raise”). The common warrants sold in the offering will be exercisable commencing on the date on which the Company (a) receives approval from its stockholders to increase the number of shares of common stock it is authorized to issue and (b) effects such stockholder approval by filing with the Secretary of State of the State of Delaware a certificate of amendment to its amended and restated certificate of incorporation, and will expire on the fifth anniversary of such initial exercise date. The combined purchase price for each share of common stock and accompanying common warrant was $0.60, which was allocated as $0.59 per share of common stock and $0.01 per common warrant.
The net proceeds to the Company from the public offering were approximately $16 million, after deducting underwriting discounts and commissions and public offering expenses payable by the Company, and excluding any proceeds the Company may receive upon exercise of the pre-funded warrants or the common warrants. The Company currently intends to use the net proceeds for the clinical development of BB-301, including the natural history lead-in study and the Phase 1b/2a BB-301 treatment study, for the continued advancement of development activities for other existing and new product candidates, for general corporate purposes and for strategic growth opportunities. The Company will have broad discretion in determining how the proceeds of the public offering will be used, and its discretion is not limited by the aforementioned possible uses.
Nasdaq Listing
On September 6, 2022, we received a letter from the Listing Qualifications Department of the Nasdaq Stock Market notifying us that the minimum bid price per share for our common stock fell below $1.00 for a period of 30 consecutive business days and that therefore we did not meet the minimum bid price requirement set forth in Nasdaq Listing Rule 5550(a)(2).
The letter also states that we will be provided 180 calendar days, or until March 6, 2023, to regain compliance with the minimum bid price requirement. In accordance with Rule 5810(c)(3)(A), we can regain compliance if at any time during the 180-day period the closing bid price of our common stock is at least $1.00 for a minimum of 10 consecutive business days. If by March 6, 2023, we cannot demonstrate compliance with the Rule 5550(a)(2), we may be eligible for additional time. To qualify for additional time, we will be required to meet the continued listing requirement for market value of publicly held shares and all other initial listing standards for The Nasdaq Capital Market, with the exception of the bid price requirement, and we will need to provide written notice of our intention to cure the deficiency during the second compliance period. If we are not eligible for the second compliance period, then the Nasdaq Staff will provide notice that our securities will be subject to delisting. At such time, we may appeal the delisting determination to a Hearings Panel.
We intend to monitor the closing bid price of our common stock and may, if appropriate, consider implementing available options to regain compliance with the minimum bid price requirement. These options include completing a reverse stock split of our common stock for the purpose of meeting the closing bid price requirement. We are seeking stockholder approval to effect a reverse stock split at our upcoming Annual Meeting of Stockholders scheduled for December 7, 2022. Completing a reverse stock split will not, in of itself, cause us to remain in compliance with Nasdaq’s listing standards.
Development Programs
Our Pipeline
The following table sets forth the current product candidate and the development status:
Table 1. Pipeline: Oculopharyngeal Muscular Dystrophy
BB-301
We are developing BB-301 for the treatment of Oculopharyngeal Muscular Dystrophy (OPMD), and BB-301 is currently undergoing evaluation in CTA-enabling and IND-enabling studies. BB-301 is the lead investigational agent under development by Benitec, and the key attributes of OPMD and BB-301 are outlined in Figure 3.
Figure 3. Overview of the BB-301 Program
BB-301 is a first-in-class genetic medicine employing the “silence and replace” approach for the treatment of OPMD. OPMD is an insidious, autosomal-dominant, late-onset, degenerative muscle disorder that typically presents in patients at 40-to-50 years of age. The disease is characterized by progressive swallowing difficulties (dysphagia) and eyelid drooping (ptosis). OPMD is caused by a specific mutation in the poly(A)-binding protein nuclear 1 gene (PABPN1).
16
OPMD is a rare disease, however, patients have been diagnosed with OPMD in at least 33 countries. Patient populations suffering from OPMD are well-identified, and significant geographical clustering has been noted for patients with this disorder. Each of these attributes could facilitate efficient clinical development and global commercialization of BB-301.
PABPN1 is a ubiquitous factor that promotes the interaction between the poly(A) polymerase and CPSF (cleavage and polyadenylation specificity factor) and, thus, controls the length of mRNA poly(A) tails, mRNA export from the nucleus, and alternative poly(A) site usage. The characteristic genetic mutation underlying OPMD results in trinucleotide repeat expansion(s) within exon 1 of PABPN1 and results in an expanded poly-alanine tract at the N-terminal end of PABPN1. The mutation generates a protein with an N-terminal expanded poly-alanine tract of up to 18 contiguous alanine residues, and the mutant protein is prone to the formation of intranuclear aggregates designated as intranuclear inclusions (INIs). The INIs that sequester wildtype PABPN1 may contribute to the “loss of function” phenotype associated with OPMD.
No therapeutic agents are approved for the treatment of OPMD. Additionally, there are no surgical interventions available to OPMD patients that modify the natural history of the disease, which is principally comprised of chronic deterioration of swallowing function. BB-301 has received Orphan Drug Designation in the United States and the European Union and, upon achievement of regulatory approval for BB-301 in these respective jurisdictions, the Orphan Drug Designations would provide commercial exclusivity independent of intellectual property protection. While OPMD is a rare medical disorder, we believe the commercial opportunity for a safe and efficacious therapeutic agent in this clinical indication exceeds $1 billion over the course of the commercial life of the product.
Benitec has previously outlined the core CTA-enabling and IND-enabling studies required by global regulatory agencies to support the initiation of BB-301 clinical trials in OPMD patients, and these studies include a BB-301 Pilot Dosing Study (the “Pilot Dosing Study”) in large animals and a classical 12-week GLP Toxicology and Biodistribution Study for BB-301. In these large animal studies, BB-301 is directly injected into the pharyngeal muscles known to underlie the morbidity and mortality which characterizes the natural history of OPMD in human subjects.
As referenced above, the BB-301 Pilot Dosing Study in large animals was the first of two CTA-enabling and IND-enabling studies conducted by Benitec. This study was carried out under the guidance of the scientific team at Benitec, with key elements of the design and execution of the study conducted in close collaboration with a team of experts in both medicine and surgery that have been deeply engaged in the treatment of OPMD patients for decades. The BB-301 Pilot Dosing Study and the GLP Toxicology and Biodistribution Study for BB-301 were conducted in canine subjects in order to:
• | Support the validation and optimization of the newly designed route and method of BB-301 administration, |
• | Confirm the efficiency of vector transduction and transgene expression in the key tissue compartments underlying the morbidity and mortality that comprises the natural history of OPMD, |
• | Confirm the optimal BB-301 doses in advance of initiation of human clinical studies, |
• | Facilitate the observation of key toxicological data-points. |
The BB-301 Pilot Dosing Study was designed as an 8-week study in Beagle dogs to confirm the transduction efficiency of BB-301 upon administration via direct intramuscular injection into specific anatomical regions of the pharynx through the use of an open surgical procedure. This new method and route of BB-301 administration was developed in collaboration with key surgical experts in the field of Otolaryngology, and this novel method of BB-301 dosing will significantly enhance the ability of treating physicians to accurately administer the AAV-based investigational agent to the muscles that underlie the characteristic deficits associated with disease progression in OPMD. It is important to note that prior BB-301 non-clinical studies have reproducibly validated the robust biological activity achieved following direct intramuscular injection of the AAV-based agent. As an example, direct injection of BB-301 into the tibialis anterior muscles of A17 mice facilitated robust transduction of the targeted skeletal muscle cells and supported complete remission of the OPMD disease phenotype in this animal model.
Benitec conducted the BB-301 Pilot Dosing Study in Beagle dog subjects to demonstrate that direct intramuscular injection of BB-301 via the use of a proprietary dosing device in an open surgical procedure could safely achieve the following goals:
• | Biologically significant and dose-dependent levels of BB-301 tissue transduction (i.e., delivery of the multi-functional BB-301 genetic construct into the target pharyngeal muscle cells), |
• | Broad-based and dose-dependent expression of the three distinct genes comprising the BB-301 gene construct within the pharyngeal muscle cells, and |
• | Biologically significant levels of target gene knock-down (i.e., inhibition of the expression of the gene of interest) within the pharyngeal muscle cells. |
The Pilot Dosing Study evaluated the safety and biological activity of two concentrations of BB-301 (1.0+E13 vg/mL and 3.0+E13 vg/mL) across three distinct doses (1.0+E13 vg/mL and 3.0+E13 vg/mL with a low injection volume, and 3.0+E13
17
vg/mL with a high injection volume) following direct intramuscular injection into the Hypopharyngeus (HP) muscles and the Thyropharyngeus (TP) muscles of Beagle dogs via the use of a proprietary delivery device employed in an open surgical procedure. The HP muscle in Beagle dogs corresponds to the Middle Pharyngeal Constrictor muscle in human subjects, and the TP muscle in Beagle dogs corresponds to the Inferior Pharyngeal Constrictor muscle in human subjects. BB-301 was injected only on Day 1 of the Pilot Dosing Study, and the corresponding canine pharyngeal muscles were harvested for molecular analyses after 8 weeks of observation post-injection. BB-301 dosing was carried out independently by a veterinary surgeon and an Otolaryngologist with extensive experience regarding the provision of palliative surgical care for OPMD patients.
Molecular analyses have been completed for the canine subjects treated in the BB-301 Pilot Dosing Study. Key interim data-sets derived from the analyses of pharyngeal muscle tissues isolated from 16 Beagle dog subjects (of the 24-subject Beagle dog study population) are highlighted below. The final data-set derived from the completed molecular analyses of the pharyngeal muscle tissues of the canine subjects treated on the Pilot Dosing Study will be presented in a peer-reviewed format.
The key interim data-sets are summarized below:

• | BB-301 encodes two distinct siRNA species (i.e., siRNA13 and siRNA17) which are each, independently, capable of inhibiting (i.e., “silencing”) the expression of the mutant form of the PABPN1 protein and the wild type (i.e., endogenous) form of the PABPN1 protein (importantly, the mutant form of the PABPN1 protein underlies the development, and progression, of OPMD). |
• | BB-301 also codes for a wild type version of the PABPN1 protein whose intracellular expression is unaffected by the inhibitory activities of siRNA13 and siRNA17; this “codon optimized” transcript drives the expression of a PABPN1 protein (i.e., coPABPN1) which serves to replenish the endogenous form of the PABPN1 protein and to replace the mutant form of PABPN1 that underlies the development and progression of OPMD in diseased tissues. |
• | For comparative purposes, it should be noted that the average range of expression for wild type PABPN1 within the pharyngeal muscle cells of Beagle dogs is 4.5 copies per cell-to-7.8 copies per cell. |

Regarding Wild Type PABPN1 Silencing (i.e., target “knock-down”) Observed for BB-301 Within the Pharyngeal Muscle Tissues (Figure 8):
• | As noted above, BB-301 encodes two distinct siRNA species (i.e., siRNA13 and siRNA17) which are each, independently, capable of inhibiting (i.e., “silencing”) the expression of all forms of the PABPN1 protein (siRNA13 and siRNA17 silence the expression of both wild type PABPN1 [wtPABPN1] and mutant PABPN1). |
• | While the Beagle dog subjects treated in the BB-301 Pilot Dosing Study do not express mutant PABPN1, the level of BB-301-driven gene silencing for the PABPN1 target can be indirectly assessed in these study subjects due to the equivalent inhibitory effects of siRNA13 and siRNA17 on both wtPABPN1 and mutant PABPN1. |
• | Thus, the wtPABPN1 silencing activity observed in the BB-301 Pilot Dosing Study serves as a surrogate for the silencing activity that would be anticipated in the presence of mutant PABPN1. |
• | BB-301 has been evaluated in prior non-clinical studies in animals that express mutant PABPN1 and, as a result, manifest the symptomatic phenotype of OPMD; in the symptomatic animal model of OPMD (i.e. the A17 mouse model), the achievement of PABPN1 silencing levels of 31% inhibition (or higher) following BB-301 administration led to resolution of OPMD disease symptoms and the elimination of the histopathological hallmarks of OPMD. |

There are key methodological distinctions between the current BB-301 Pilot Dosing Study conducted by Benitec as compared to the prior BB-301 Beagle dog dosing study carried out independently by the previous BB-301 licensee. The BB-301 dosing study conducted by the prior BB-301 licensee employed non-ideal routes and methods of BB-301 administration to the target pharyngeal muscle tissues and employed similarly limited analytical methods at the completion of the dosing phase of the study. Subsequently, the Benitec team worked to optimize the route and method of administration of BB-301 and to refine the core analytical methods employed following the completion of dosing of the large animal subjects.
The current proprietary method of BB-301 delivery to the key pharyngeal muscles of study subjects, and the proprietary molecular analytical methods employed to assay the pharyngeal muscle tissues of study subjects, with both methods having been developed by the Benitec team, led to the observation of broad-based transduction of the targeted pharyngeal muscle tissues (Figure 9, represents individual sections of the TP muscle following BB-301 dosing). Critically, the Benitec-developed methods also facilitated the achievement of a 228-fold improvement (+22,647%) in BB-301 transduction of the HP muscle and a 113-fold improvement (+11,163%) in BB-301 transduction of the TP muscle relative to the levels of BB-301 transduction observed by the previous BB-301 licensee at identical BB-301 doses in identical canine study populations (Figure 10).

Following the disclosure of the positive interim BB-301 Pilot Dosing Study results, Benitec completed pre-CTA and pre-IND meetings with regulatory agencies in France, Canada, and the United States.
Summary of Regulatory Interactions:
• | Benitec successfully completed the regulatory interactions required to support initiation of the OPMD clinical development program in 2022 |
• | Successful regulatory engagement comprised the completion of the following meetings: |
• | Preclinical Trial Application (Pre-CTA) Consultation Meeting with Health Canada |
• | Scientific Advice Meeting with The National Agency for the Safety of Medicines and Health Products in France (L’Agence nationale de sécurité du médicament et des produits de santé or “ANSM”) |
• | Type C Meeting with the U.S. Food and Drug Administration (“FDA”) |
Benitec will begin the OPMD clinical development program in 2022.
Summary of the BB-301 Clinical Development Program:
• | The BB-301 clinical development program will begin in 2022, and the conduct of the development program will comprise approximately 76-weeks of follow-up for each OPMD study participant, inclusive of: |
• | 6-month pre-treatment observation periods employing quantitative radiographic imaging techniques for evaluation of the baseline disposition and natural history of OPMD-derived dysphagia in each study participant |
22
• | 1 day of BB-301 dosing to initiate participation in the Phase 1b/2a single-arm, open-label, sequential, dose escalation cohort study |
• | 52-weeks of post-dosing follow-up for conclusive evaluation of the primary and secondary endpoints of the Phase 1b/2a BB-301 treatment study |
• | The OPMD Natural History Study will begin in 2022, and this observational study will facilitate the characterization of OPMD patient disposition at baseline and assess subsequent rates of progression of dysphagia (swallowing impairment) in subjects with OPMD via the use of quantitative radiographic measures of global swallowing function and pharyngeal constrictor muscle function along with clinical assessments and patient-reported self-assessments of swallowing function |
• | Videofluoroscopic Swallowing Studies (VFSS) will be conducted to complete the following methodological assessments: |
• | Dynamic Imaging Grade of Swallowing Toxicity Scale (DIGEST) |
• | Pharyngeal Area at Maximum Constriction (PhAMPC) |
• | Pharyngeal Constriction Ratio (PCR) |
• | Clinical measures of global swallowing capacity and oropharyngeal dysphagia |
• | Patient-reported measures of oropharyngeal dysphagia |
• | The natural history of dysphagia observed for each OPMD study participant, as characterized by the quantitative radiographic measures and the clinical and patient self-reported assessments outlined above, will serve as the baseline for comparative assessments of safety and efficacy of BB-301 upon rollover of OPMD study subjects from the Natural History Study onto the Phase 1b/2a BB-301 treatment study |
23
• | Upon the achievement of 6-months of follow-up in the Natural History Study, OPMD Natural History Study participants can become eligible for enrollment onto the Phase 1b/2a treatment study with the investigational genetic medicine, BB-301, which uses an AAV9-based gene therapy approach for the treatment of OPMD-derived dysphagia |
• | This first-in-human (FIH) clinical trial will be a Phase 1b/2a, open-label, dose escalation study to evaluate the safety and clinical activity of intramuscular doses of BB-301 administered to the pharyngeal muscles of subjects with OPMD |
• | Upon rollover from the Natural History Study onto the Phase 1b/2a BB-301 treatment study, the follow-up of OPMD study participants will continue for 52-weeks, and the primary endpoints (safety and tolerability) and secondary endpoints (comprising the quantitative radiographic measures of global swallowing function and pharyngeal constrictor muscle function, and the clinical and patient-reported assessments noted above) will be evaluated during each 90-day period following Day 1 (Day 1 represents the day of BB-301 intramuscular injection). |
Royalties, milestone payments and other license fees
We are required to pay royalties, milestone payments and other license fees in connection with our licensing of intellectual property from third parties, including as discussed below.
We have collaborated with Biomics Biotechnologies Co., Ltd., or Biomics, pursuant to several collaboration agreements in relation to single-stranded RNA and shRNA sequences for treatment of hepatitis B. In July 2015, we entered into an earn-out agreement with Biomics which confirmed Benitec’s ownership of certain patents resulting from the collaboration in exchange for an upfront payment and equity issuance to Biomics and a share of certain future licensing revenue received by Benitec.
October 2020 Capital Raise
On October 6, 2020, the Company announced the closing of an underwritten public offering of common stock and common stock equivalents. The Company received gross proceeds of approximately $11.5 million and net proceeds of approximately $9.9 million from the offering.
April 2021 Capital Raise
On April 30, 2021, the Company announced the closing of an underwritten public offering of common stock and common stock equivalents. The Company received gross proceeds of approximately $14.3 million and net proceeds of approximately $12.7 million from the offering.
September 2022 Capital Raise
On September 15, 2022, the Company announced the closing of an underwritten public offering of common stock and common stock equivalents. The Company received gross proceeds of approximately $17.9 million and net proceeds of approximately $16.0 million from the offering.
Results of Operations
Revenues
The Company has not generated any revenues from the sales of products. Revenues from licensing fees are included in the revenue from customers line item on our consolidated statements of operations and comprehensive loss. Our licensing fees have been generated through the licensing of our ddRNAi technology to biopharmaceutical companies. The Company did not recognize any revenue during the three months ended September 30, 2022 and September 30, 2021.
24
Royalties and License Fees
Royalties and license fees consist primarily of payments we are required to remit for royalties and other payments related to in-licensed intellectual property. Under our in-license agreements, we may pay up-front fees and milestone payments and be subject to future royalties. We cannot precisely predict the amount, if any, of royalties we will owe in the future, and if our calculations of royalty payments are incorrect, we may owe additional royalties, which could negatively affect our results of operations. As our product sales increase, we may, from time to time, disagree with our third-party collaborators as to the appropriate royalties owed, and the resolution of such disputes may be costly, may consume management’s time, and may damage our relationship with our collaborators. Furthermore, we may enter into additional license agreements in the future, which may also include royalty, milestone and other payments.
Research and Development Expenses
Research and development expenses relate primarily to the cost of conducting clinical and preclinical trials. Preclinical and clinical development costs are a significant component of research and development expenses. The Company records accrued liabilities for estimated costs of research and development activities conducted by third-party service providers, which include the conduct of preclinical studies and clinical trials, and contract manufacturing activities. The Company records the estimated costs of research and development activities based upon the estimated amount of services provided but not yet invoiced and includes these costs in trade and other payables on the consolidated balance sheets and within research and development expenses on the consolidated statements of operations and comprehensive loss.
The Company accrues for these costs based on factors such as estimates of the work completed and in accordance with agreements established with its third-party service providers. The Company makes significant judgments and estimates in determining the accrued liabilities balance at the end of each reporting period. As actual costs become known, the Company adjusts its accrued liabilities. The Company has not experienced any material differences between accrued costs and actual costs incurred.
General and Administrative Expenses
General and administrative expenses consist primarily of salaries, related benefits, travel, and equity-based compensation expense. General and administrative expenses also include facility expenses, professional fees for legal, consulting, accounting and audit services and other related costs.
We anticipate that our general and administrative expenses may increase as the Company focuses on the continued development of the preclinical OPMD program. The Company also anticipates an increase in expenses relating to accounting, legal and regulatory-related services associated with maintaining compliance with exchange listing and SEC requirements, director and officer insurance premiums and other similar costs.

During the three months ended September 30, 2022 and September 30, 2021, respectively, we incurred $2.7 million and $2.8 million in research and development expenses, respectively. Research and development expenses relate primarily to the OPMD project. The Company continued with the GMP manufacturing project after concluding the BB-301 Regulatory Toxicology Study and the Parallel Assay Method Development, Qualification, and Validation project.
General and administrative expense totaled $1.9 million and $2.0 million for the three months ended September 30, 2022 and September 30, 2021, respectively. The decrease for the three-month period was due to decreases in salaries and wages, insurance, and state and local taxes.

The other income (loss), net during the three months ended September 30, 2022 and September 30, 2021, respectively, totaled $(513) thousand and $(223) thousand, which consists of foreign currency transaction losses, interest expense, and unrealized gain on investment. Foreign currency transaction losses have increased due to a change in foreign exchange rates. Unrealized gain on investment decreased for the three months ended September 30, 2022, compared to the three months ended September 30, 2021.
Liquidity and Capital Resources
The Company has incurred cumulative losses and negative cash flows from operations since our predecessor’s inception in 1995. The Company had accumulated losses of $153 million as of September 30, 2022. We expect that our research and development expenses may increase due to the continued development of the OPMD program. It is also likely that there will be an increase in the general and administrative expenses due to the obligations of being a domestic public company in the United States.
We had no borrowings as of September 30, 2022 and do not currently have a credit facility.
As of September 30, 2022, we had cash and cash equivalents of approximately $16.5 million. Cash in excess of immediate requirements is invested in accordance with our investment policy, primarily with a view to liquidity and capital preservation. Currently, our cash and cash equivalents are held in bank accounts.

Operating activities
Net cash used in operating activities for the three months ended September 30, 2022 and 2021 was $4.0 million and $4.3 million, respectively. Net cash used in operating activities was primarily the result of our net loss, partially offset by non-cash expenses, and changes in working capital, including an increase in payables.
27
Financing activities
Net cash provided by financing activities was $16.0 million and $0 for the three months ended September 30, 2022 and 2021, respectively. Cash from financing activities in 2022 was related to the issuance of common stock, pre-funded warrants, and Series 2 warrants, including $17.9 million in gross proceeds from the September 2022 Capital Raise, partially offset by $1.9 million in share issuance costs.
The future of the Company as an operating business will depend on its ability to manage operating costs and budgeted amounts and obtain adequate financing. While we continue to progress discussions and advance opportunities to engage with pharmaceutical companies and continue to seek licensing partners for ddRNAi in disease areas that are not our focus, there can be no assurance as to whether we will enter into such arrangements or what the terms of any such arrangement could be.
While we have established some licensing arrangements, we do not have any products approved for sale and have not generated any revenue from product sales. We do not know when, or if, we will generate any revenue from product sales. We do not expect to generate significant revenue from product sales unless and until we obtain regulatory approval of and commercialize one of our current or future product candidates.
Unless and until we establish significant revenues from licensing programs, strategic alliances or collaboration arrangements with pharmaceutical companies, or from product sales, we anticipate that we will continue to generate losses for the foreseeable future, and we expect the losses to increase as we continue the development of product candidates and begin to prepare to commercialize any product that receives regulatory approval. We are subject to the risks inherent in the development of new gene therapy products, and we may encounter unforeseen expenses, difficulties, complications, delays, and other unknown factors that may adversely affect our business. We estimate that our cash and cash equivalents will be sufficient to fund the Company’s operations for at least the next twelve months.
We have based our projections of operating capital requirements on assumptions that may prove to be incorrect and we may use all of our available capital resources sooner than we expect. Because of the numerous risks and uncertainties associated with research, development, and commercialization of pharmaceutical products, we are unable to estimate the exact amount of our operating capital requirements. Our future funding requirements will depend on many factors, including, but not limited to:
• | the timing and costs of our planned clinical trials for our ddRNAi and silence and replace product candidates; |
• | the timing and costs of our planned preclinical studies for our ddRNAi and silence and replace product candidates; |
• | the number and characteristics of product candidates that we pursue; |
• | the outcome, timing, and costs of seeking regulatory approvals; |
• | revenue received from commercial sales of any of our product candidates that may receive regulatory approval; |
• | the terms and timing of any future collaborations, licensing, consulting, or other arrangements that we may establish; |
• | the amount and timing of any payments we may be required to make, or that we may receive, in connection with the licensing, filing, prosecution, defense and enforcement of any patents or other intellectual property rights; |
• | the costs of preparing, filing and prosecuting patent applications, maintaining and protecting our intellectual property rights and defending against intellectual property related claims; and |
• | the extent to which we need to in-license or acquire other products and technologies. |
Contractual Obligations and Commercial Commitments
On October 1, 2016, the Company entered into an operating lease for office space in Hayward, California that originally expired in April 2018. The Company has entered into lease amendments that extended the lease through June 2025. See Note 8.
The Company enters into contracts in the normal course of business with third-party contract research organizations, contract development and manufacturing organizations and other service providers and vendors. These contracts generally provide for termination on notice and, therefore, are cancellable contracts and not considered contractual obligations and commitments.
Critical Accounting Policies and Significant Accounting Estimates
The preparation of consolidated financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires management to make judgments, assumptions and estimates that affect the amounts reported. Note 2 of the Notes to Consolidated Financial Statements included in this Quarterly Report on Form 10-Q describes the significant accounting policies used in the preparation of the consolidated financial statements. Certain of these significant accounting policies are considered to be critical accounting policies.
28
A critical accounting policy is defined as one that is both material to the presentation of the Company’s consolidated financial statements and requires management to make difficult, subjective, or complex judgments that could have a material effect on the Company’s financial condition or results of operations. Specifically, these policies have the following attributes: (1) the Company is required to make assumptions about matters that are highly uncertain at the time of the estimate; and (2) different estimates the Company could reasonably have used, or changes in the estimate that are reasonably likely to occur, would have a material effect on the Company’s financial condition or results of operations.
Estimates and assumptions about future events and their effects cannot be determined with certainty. The Company bases its estimates on historical experience and on various other assumptions believed to be applicable and reasonable under the circumstances. These estimates may change as new events occur, as additional information is obtained and as the Company’s operating environment changes. These changes have historically been minor and have been included in the consolidated financial statements as soon as they became known. In addition, management is periodically faced with uncertainties, the outcomes of which are not within its control and will not be known for prolonged periods of time. These uncertainties are discussed in the section above entitled “Risk Factors.” Based on a critical assessment of its accounting policies and the underlying judgments and uncertainties affecting the application of those policies, management believes that the Company’s consolidated financial statements are fairly stated in accordance with accounting principles generally accepted in the United States of America and provide a meaningful presentation of the Company’s financial condition and results of operations.
Management believes that the following are critical accounting policies:
Research and Development Expense
Research and development expenses relate primarily to the cost of conducting clinical and preclinical trials. Preclinical and clinical development costs are a significant component of research and development expenses. The Company records accrued liabilities for estimated costs of research and development activities conducted by third-party service providers, which include the conduct of preclinical studies and clinical trials, and contract manufacturing activities. The Company records the estimated costs of research and development activities based upon the estimated amount of services provided but not yet invoiced and includes these costs in trade and other payables on the consolidated balance sheets and within research and development expenses on the consolidated statements of operations and comprehensive loss.
The Company accrues for these costs based on factors such as estimates of the work completed and in accordance with agreements established with its third-party service providers. The Company makes significant judgments and estimates in determining the accrued liabilities balance at the end of each reporting period. As actual costs become known, the Company adjusts its accrued liabilities. The Company has not experienced any material differences between accrued costs and actual costs incurred.
Share-based Compensation Expense
The Company records share-based compensation in accordance with ASC 718, Stock Compensation. ASC 718 requires the fair value of all share-based employee compensation awarded to employees and non-employees to be recorded as an expense over the shorter of the service period or the vesting period. The Company determines employee and non-employee share-based compensation based on grant-date fair value using the Black-Scholes Option Pricing Model.

New Accounting Standards and Interpretations not yet mandatory or early adopted
ASU 2016-13-In June 2016, the FASB issued ASU No. 2016-13: “Financial Instruments-Credit Losses (Topic 326)”. This ASU represents a significant change in the accounting for credit losses model by requiring immediate recognition of management’s estimates of current expected credit losses (CECL). Under the prior model, losses were recognized only as they were incurred. The Company has determined that it has met the criteria of a smaller reporting company (“SRC”) as of November 15, 2019. As such, ASU 2019-10: “Financial Instruments-Credit Losses, Derivatives and Hedging, and Leases: Effective Dates” amended the effective date for the Company to be for reporting periods beginning after December 15, 2022. The Company will adopt this ASU effective July 1, 2023.

Item 3. Quantitative and Qualitative Disclosures About Market Risk
As a smaller reporting company, we are not required to provide the information pursuant to this Item.
Item 4. Controls and Procedures
We have established disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended). As of the end of the period covered by this Report we carried out an evaluation under the supervision and with the participation of our management, including our principal executive officer and principal financial and accounting officer, of the effectiveness of our disclosure controls and procedures pursuant to Rule 13a-15 of the Securities and Exchange Act of 1934, as amended. Based upon that evaluation, our principal executive officer and principal financial and accounting officer concluded that our disclosure controls and procedures are effective.
There were no changes in our internal controls over financial reporting during the quarter ended September 30, 2022 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
We do not expect that our disclosure controls and procedures or our internal controls will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected.
