PRINCETON, N.J., Aug. 14, 2024 (GLOBE NEWSWIRE) -- Sonnet BioTherapeutics Holdings, Inc. (the “Company” or “Sonnet”) (NASDAQ: SONN), a clinical-stage company developing targeted immunotherapeutic drugs, today reported financial results for the three and nine months ended June 30, 2024 and provided a corporate update.
“We continue to be encouraged with the data generated by our lead program SON-1010. While preliminary, demonstrating evidence of clinical benefit at 4 months in 35% of evaluable patients in both of our ongoing studies of SON-1010 represents a significant opportunity to help patients with PROC and address an indication in desperate need of innovative therapies,” commented Pankaj Mohan, Ph.D., Founder and CEO of Sonnet. “Additionally, we are actively working to identify a partner to help advance our SON-080 program through the next phases of development and potentially address a significant unmet need in diabetic peripheral neuropathy.”
Recent Highlights
Patent Update
“We remain committed to strengthening the intellectual property portfolio for our FHAB enabling technology platform and are pleased to further expand our patent estate in this key territory for Sonnet with this granted U.S. patent for SON-1210, our dual-targeting cytokine. We believe that including SON-1210 in our unique platform may create a next generation cancer treatment that can enhance patients’ own immune systems to fight cancer. We look forward to identifying a development pathway through a collaboration for the continued advancement of SON-1210 and offering patients with cancer a much needed therapeutic option,” added Pankaj Mohan, Ph.D., Founder and CEO of Sonnet.
Lead Clinical Programs Update
SON-1010: Targeted Immune Activation Cancer Therapy, Turning ‘Cold’ Tumors ‘Hot’ Initially Targeting Solid Tumors and Platinum-Resistant Ovarian Cancer (PROC)
Phase 1 Trial (SB101 Trial): Solid Tumors (Monotherapy)
This first-in-human study is primarily designed to evaluate the safety of multiple ascending doses of SON-1010 in cancer patients and is being conducted at several sites across the United States.
For more information about the SB101 clinical trial, visit clinicaltrials.gov and reference identifier NCT05352750.
Phase 1b/2a Trial (SB221 Trial): PROC (Combo with Atezolizumab)
The second trial is a global Phase 1b/2a multicenter, dose-escalation and randomized proof-of-concept study to assess the safety, tolerability, PK, PD, and efficacy of SON-1010 administered subcutaneously (SC) in combination with atezolizumab given intravenously (IV).
For more information about the SB221 clinical trial, visit clinicaltrials.gov and reference identifier NCT05756907.

SON-080: Low dose of rhIL-6 for Chemotherapy-Induced Peripheral Neuropathy (CIPN) and Diabetic Peripheral Neuropathy (DPN)
Phase 1b/2a Trial (SB211 Trial): Chemotherapy Induced Peripheral Neuropathy (CIPN)
The SB211 study is a double-blind, randomized, controlled trial of SON-080 conducted at two sites in Australia in patients with persistent CIPN using a new proprietary version of recombinant human Interleukin-6 (rhIL-6) that builds upon previous work with atexakin alfa. The goal of the Phase 1b portion of the SB211 study was to confirm safety and tolerability before continued development in Phase 2. As previously announced in March 2024, a data and safety monitoring board reviewed the unblinded safety and tolerability of SON-080 in the first nine patients and concluded that the symptoms were tolerable in the initial patients and the study could proceed to Phase 2.

SON-080 Upcoming Milestones
Summary of Financial Results for the Third Quarter 2024
As of June 30, 2024, Sonnet had $3.6 million cash on hand, which the Company believes is sufficient to fund operations into November 2024.
Research and development expenses were $1.7 million for the three months ended June 30, 2024, compared to $2.4 million for the three months ended June 30, 2023. The decrease of $0.7 million was primarily due to cost saving initiatives, as the Company is managing expenses for liquidity purposes and is tightening its focus on the research and development projects it has assessed to have the greatest near-term potential. In addition to transitioning product development activities to cost advantaged locations such as India and Australia, the Company has reduced expenditures on tertiary programs and suspended antiviral development related to SON-1010, as well as programs related to SON-080 and SON-1210 while it seeks potential partnering opportunities.
General and administrative expenses were $1.8 million for the three months ended June 30, 2024, compared to $1.5 million for the three months ended June 30, 2023. The increase of $0.3 million related primarily to costs incurred in connection with the May 2024 ChEF Purchase Agreement entered into with Chardan Capital Markets LLC and an increase in legal and professional expenses and franchise taxes, partially offset by a decrease in consulting expenses related to licensing.
