- Data announced from two clinical trials of SON-1010 in both healthy volunteers and patients with advanced solid tumors
- Entered into collaboration with Janssen Biotech for the evaluation of three Sonnet pipeline compounds
- Successfully completed two IND-enabling toxicology studies with SON-1210 in non-human primate
PRINCETON, NJ / ACCESSWIRE / February 13, 2023 / Sonnet BioTherapeutics Holdings, Inc. (NASDAQ:SONN) ("Sonnet" or the "Company"), a biopharmaceutical company developing innovative targeted biologic drugs, announced today its financial results for the three months ended December 31, 2022 and provided a business update.
"This was a productive quarter for Sonnet and one of which we are particularly proud. We believe the successful early clinical data we announced sets the stage for SON-1010 as a potentially best-in-class IL-12 therapeutic candidate with unique properties for targeting the tumor microenvironment," commented Pankaj Mohan, Ph.D., Founder and CEO. "Our prioritized business development initiatives culminated in the work Janssen is currently undertaking to evaluate three of our pipeline assets. We continue to progress our platform with our first bispecific, bifunctional pipeline compound, SON-1210, a first-in-class combination of interleukins 12 and 15 and we look forward to delivering on our 2023 research and development initiatives while remaining focused on partnering as a key component of our strategy."
"Having recently completed a $15 million financing, we are advancing our stated objective to reduce operating expenses by approximately 30% beginning in our second fiscal quarter, with an eye to making additional cuts to further extend our cash runway. These next few quarters will play an important role in shaping Sonnet's future, and we remain confident in the promise of our FHAB technology," said Jay Cross, CFO.
FY 2023 First Quarter and Recent Corporate Updates
Sonnet provided the following corporate updates:
- On October 31, 2022, announced a collaboration agreement with Janssen Biotech, Inc. (Janssen), one of the Janssen Pharmaceutical Companies of Johnson & Johnson, where in vitro and in vivo efficacy of SON-1010 (IL12-FHAB), SON-1210 (IL12-FHAB-IL15) and SON-1410 (IL18-FHAB-IL12) will be evaluated in combination with certain Janssen proprietary cell therapy assets. The agreement was facilitated by Johnson & Johnson Innovation.
- On November 2, 2022, announced interim data from the SB101 and SB102 Phase 1 dose-escalation trials of SON-1010. At the time of the press release, 36 subjects had been dosed across the two studies, where cytokine data showed extended pharmacokinetics of SON-1010 with controlled induction of IFNγ and no signs of cytokine release syndrome, or dose-limiting toxicities. Subsequent to this announcement, on January 19, 2023, Sonnet announced follow-up data from the SB102 study in a total of 24 healthy volunteers, where the PK profile supported an extended half-life of SON-1010 of approximately 112 hours, compared to 12 hours for rhIL-12. Observed increases in IFNγ were dose-related, controlled and prolonged. Sonnet expects to announce additional data from both studies during the second calendar quarter of 2023.
- During December 2022, successfully completed two IND-enabling toxicology studies with SON-1210 in non-human primates. As announced on January 19, 2023, the compound elicited no serious adverse events in repeat, subcutaneous dosing and was well-tolerated using dosing levels at least 50x higher than the highest anticipated human clinical dose level. Data analysis and reporting for both of the studies will enable the preparation of regulatory filings to begin during the first half of 2023 for first-in-human trials of SON-1210.
FY 2023 First Quarter Ended December 31, 2022 Financial Results
- As of December 31, 2022, Sonnet had $1.7 million cash on hand and $0.0 million in debt. On February 10, 2023, the company closed a public offering for gross proceeds of $15 million (net proceeds of approximately $13.5 million), issuing 11,664,888 shares of common stock, pre-funded warrants to purchase 2,224,000 shares of common stock, with an exercise of $0.0001 per share, and common warrants to purchase 27,777,776 shares of common stock, with an exercise price of $1.08 per share. After the offering, the Company has 20,232,904 shares of common stock outstanding.
- Research and development expenses were $3.7 million for the three months ended December 31, 2022, compared to $4.3 million for the three months ended December 31, 2021. The decrease of $0.6 million was primarily due to the establishment of cost savings by transitioning product development activities to cost advantaged locations such as India and Australia and by reducing expenditures on tertiary programs such as SON-3015, which has been placed on a development hold, as well as a decrease in share-based compensation expense.
- General and administrative expenses were $1.9 million for the three months ended December 31, 2022, compared to $2.1 million for the three months ended December 31, 2021. The decrease of $0.2 million relates primarily to a decrease in share-based compensation expense and consulting expense related to investor relations.
