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 became exercisable on December 9, 2022, the date by which the Company (a) received approval from its stockholders to increase the number of shares of common stock it is authorized to issue and (b) effected 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 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. On March 7, 2023, Nasdaq notified the Company in writing that while the Company had not regained compliance with the minimum bid price requirement, it was eligible for an additional 180 calendar day period, or until September 5, 2023, to regain compliance with the minimum bid price requirement. Nasdaq’s determination was based on the Company having met the continued listing requirement for market value of publicly held shares and all other applicable requirements for initial listing on The Nasdaq Capital Market, with the exception of the minimum bid price requirement and on the Company’s written notice to Nasdaq of its intention to cure the deficiency during the second compliance period by effecting a reverse stock split, if necessary. If at any time during this additional time period the closing bid price of the Company’s common stock is at least $1.00 per share for a minimum of 10 consecutive business days, Nasdaq will provide written confirmation of compliance and the matter will be closed.
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 received stockholder approval to effect a reverse stock split at our Annual Meeting of Stockholders on December 7, 2022 but currently have no plans to proceed. Such approval allows our board of directors, in its discretion, to elect to implement such reverse stock split at any time prior to December 7, 2023. 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). 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).
