PRINCETON, NJ / ACCESSWIRE / August 15, 2022 / 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 June 30, 2022 and provided a business update.
"Sonnet is proud of its progress to date, with two clinical programs in SON-1010 and SON-080 currently advancing in human studies," said Pankaj Mohan, Ph.D., Founder and CEO. "During the fourth quarter of this year, we anticipate releasing initial safety and tolerability data from the SB101 study in oncology patients and the SB102 study in healthy volunteers. The initial pharmacokinetic and pharmacodynamic data from both studies should be available later this year, as well. Taken together, we anticipate that these trials will help the company optimize the clinical development strategies underpinning our multiple FHAB platform-based bispecific immunotherapy candidates."
"We remain focused on an effective financing strategy to help advance Sonnet's growth and we are excited to continue our work with the FHAB technology, which we believe carries significant value for oncology therapeutic development," commented Jay Cross, CFO.
FY 2022 Third Quarter and Recent Corporate Updates
Sonnet provided the following corporate updates:
- Initiated a second Phase 1 clinical trial of SON-1010 (IL12-FHAB), based on the successful initiation of the first two cohorts in the first-in-human (FIH) dose-escalation trial (SB101) in patients with advanced solid tumors; initial safety and tolerability data from the SB101 and SB102 studies expected during the calendar fourth quarter of this year; initial PK and PD data from both studies should also be available before the end of 2022
- Initiated a Phase 1b/2a clinical trial of SON-080; this new study (SB211) will be conducted at multiple sites in Australia in patients with persistent chemotherapy-induced peripheral neuropathy (CIPN); initial safety data from this study are expected during the first half of 2023
- Announced positive data from a preclinical combination study of SON-1010 with a commercially available anti-PD1 compound; combination increased survival rate in the study
- Completion of the non-human primate (NHP) toxicology studies with SON-1210 is anticipated by the end of 2022; we expect to initiate the regulatory authorization process in the first half of 2023
- Completed sequence confirmation for SON-3015 and preparing for initial in vivo mice studies during the calendar fourth quarter of this year
FY 2022 Third Quarter Ended June 30, 2022 Financial Results
- As of June 30, 2022, Sonnet had $5.2 million cash on hand.
- Research and development expenses were $5.6 million for the three months ended June 30, 2022, compared to $3.9 million for the three months ended June 30, 2021. The increase of $1.8 million was primarily due to increased expenditures for the development of the cell lines for IL12-FHAB, IL12-FHAB-IL15 and SON-080 in connection with the initiation of a Phase 1 clinical trial for SON-1010 and preparation for a Phase 1b/2a pilot-scale efficacy study with SON-080 in CIPN, the milestone payment incurred in connection with the XOMA Collaboration Agreement, and an increase in payroll expense as we continue to develop our product candidates.
- General and administrative expenses were $2.3 million for the three months ended June 30, 2022, compared to $2.4 million for the three months ended June 30, 2021. The decrease of $0.1 million related primarily to a decrease in share-based compensation expense as a result of the restricted stock units issued in 2020 becoming fully vested at the beginning of April 2022 and a decrease in payroll expense as certain executives devoted more of their time to research and development activities, partially offset by an increase in consulting and professional fees.
At-the-Market Offering
Sonnet entered into an At-the-Market Sales Agreement with BTIG, LLC ("BTIG") on August 15, 2022 (the "Sales Agreement").
