PRINCETON, NJ / ACCESSWIRE / May 17, 2021 / 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 March 31, 2021 and provided a business update.

"Over the course of the quarter, we have made several advancements across our pipeline products, most notably of which are the completion of non-human primate (NHP) toxicology study of SON-080 and the completion of a repeat dose study of SON-1010 in NHPs," commented Pankaj Mohan, Ph.D., Founder and CEO. "Additionally, we were thrilled to have our abstract detailing data from our NHP study of SON-1010 accepted for presentation at the American Association for Cancer Research (AACR) Annual Meeting."

FY 2021 Second Quarter and Recent Corporate Updates

Sonnet provided the following updates on its lead pipeline assets:

The Company successfully completed multiple NHP GLP toxicology studies with SON-1010 (FHAB-IL12) and is generating data to prepare an IND submission to initiate clinical studies in the second half of 2021.

Regarding SON-080, the Company intends to file a US IND to initiate a Phase 1b/2a pilot-scale efficacy study in the Chemotherapy-Induced Peripheral Neuropathy (CIPN) indication during the second half of 2021. Additionally, as part of the recently announced partnership with New Life Therapeutics, the companies intend to file an ex-US IND equivalent for a Phase 1b/2a pilot-scale efficacy study in Diabetic Peripheral Neuropathy (DPN) during the second half of 2021. Going forward, Sonnet will exclusively refer to the low-dose IL-6 programs, namely CIPN and DPN, using the SON-080 designation, the latter of which had previously been known as the SON-081 program.

The Company's first bispecific candidate, SON-1210 (IL-FHAB-IL15), is undergoing cell line and process development activities. Sonnet expects completion of NHP studies in the second half of this year with an IND submission during the first half of 2022.

Sonnet has manufactured bi-specific preclinical constructs of SON-2014 (GMcSF-FHAB-IL18), as well as IL18-FHAB-IL12 and IL12-FHAB-GMcSF that are being evaluated for in vivo efficacy, biomarker profiles and fluorescence-activated cell sorting (FACS) assessment in single dose and multi-dose preclinical studies. The Company intends to initiate commercial cell line development necessary for future clinical studies, with an IND submission for SON-2014 targeted for the second half of 2022.

Sonnet has added key senior management hires of Richard Kenney, M.D. as Chief Medical Officer and Manuel Dafonseca as Head of Clinical Operations, as the Company prepares to advance its FHAB platform into its first clinical study.

"During the quarter, we were able to successfully draw from our at-the-market sales agreement with BTIG and bring in over $10 million of capital to the Company", commented Jay Cross, CFO. "This additional funding will enable us to continue driving our R&D activities forward and furthers our goal of bringing much need therapeutic advancements to patients."

FY 2021 Second Quarter Ended March 31, 2021 Financial Results

  • As of March 31, 2021, Sonnet had $6.7 million cash on hand.
  • As previously announced, on February 5, 2021, Sonnet entered into an at-the-market sales agreement with BTIG, LLC, for an aggregate offering of up to $15.9 million. Through March 31, 2021, the Company sold an aggregate of 4,021,561 shares for net proceeds of $10.2 million to Sonnet. The company has not sold shares though this facility since March 12, 2021.
  • Research and development expenses were $3.8 million for the three months ended March 31, 2021, compared to $1.3 million for the three months ended March 31, 2020. The increase of $2.5 million was primarily due to increased expenditures for the development of the cell line for IL12-FHAB and IL12-FHAB-IL15.
  • General and administrative expenses were $2.2 million for the three months ended March 31, 2021, compared to $1.3 million for the three months ended March 31, 2020. The increase of $1.0 million was primarily due to an increase in insurance expense of related to directors and officer's insurance, and in increase in payroll and share-based compensation expense to support our expanded operations.
