Description of business
Sonnet BioTherapeutics, Inc. (“Sonnet”) was incorporated as a New Jersey corporation on April 6, 2015. Sonnet is a clinical stage, oncology-focused biotechnology company with a proprietary platform for innovating biologic medicines of single- or bi-specific action. Known as FHAB™ (Fully Human Albumin Binding), the technology utilizes a fully human single chain antibody fragment (scFv) that binds to and “hitch-hikes” on human serum albumin (HSA) for transport to target tissues. Sonnet’s lead proprietary asset, SON-1010, is a fully human version of Interleukin 12 (“IL-12”), covalently linked to the FHAB construct, for which Sonnet intends to pursue clinical development in solid tumor indications, including non-small cell lung cancer and head and neck cancer. Sonnet has completed a nonhuman primate (“NHP”) GLP toxicity study and has successfully manufactured drug product for clinical use. Sonnet has submitted an Investigational New Drug (“IND”) application to the FDA and intends to submit additional product stability data in the first quarter of 2022. Subject to FDA approval, Sonnet is preparing to initiate a U.S. clinical trial in oncology patients with solid tumors during the first half of 2022. Sonnet is also preparing to initiate an Australian clinical study in healthy volunteers during the first half of 2022. The Company acquired the global development rights to its most advanced compound, SON-080, a fully human version of Interleukin 6 (“IL-6”), in April 2020. Sonnet is advancing SON-080 in target indications of Chemotherapy-Induced Peripheral Neuropathy (“CIPN”) and Diabetic Peripheral Neuropathy (“DPN”). Sonnet intends to file for an ex-US Phase 1b/2a pilot-scale efficacy study with SON-080 in CIPN during the first half of 2022. This study could yield initial top line clinical safety data during the second half of 2022. Pursuant to a license agreement the Company entered with New Life Therapeutics Pte., Ltd (“New Life”) of Singapore in May 2021, Sonnet and New Life will be jointly responsible for developing SON-080 in DPN with the objective of initiating an ex-US pilot-scale efficacy study in the second half of 2022. SON-1210 (IL12-FHAB-IL15), Sonnet’s lead bispecific construct, combines FHAB with fully human IL-12 and fully human Interleukin 15 (IL-15). This compound is being developed for solid tumor indications, including colorectal cancer, and Sonnet expects to initiate the regulatory authorization process in the second half of 2022. In September 2021, the Company created a wholly-owned Australian subsidiary, SonnetBio Pty Ltd, for the purpose of conducting certain clinical trials.
Merger with Chanticleer
On April 1, 2020, Sonnet completed its merger (the “Merger”) with publicly-held Chanticleer Holdings, Inc. (“Chanticleer”) in accordance with the terms of the Plan of Merger dated October 10, 2019, as amended by Amendment No. 1 on February 7, 2020 (the “Merger Agreement”). Immediately prior to the Merger, Chanticleer spun-off its restaurant operations to a spin-off entity and no assets or liabilities of the restaurant business remained after the spin-off. After the Merger, Chanticleer changed its name to Sonnet BioTherapeutics Holdings, Inc. (“Sonnet Holdings” or the “Company”) and is focused on advancing Sonnet’s pipeline of oncology candidates and the strategic expansion of Sonnet’s technology platform into other human diseases.
Under the terms of the Merger Agreement, the Company issued shares of common stock to Sonnet’s stockholders. Sonnet Holdings assumed all outstanding and unexercised Chanticleer warrants which were converted into warrants to purchase common stock of Sonnet Holdings. In addition, Sonnet paid Chanticleer $6.0 million as a condition of closing and issued warrants to the spin-off entity.
For accounting purposes, Sonnet is considered the acquiring company and the Merger has been accounted for as a reverse acquisition and recapitalization with Sonnet being treated as the accounting acquirer. As such, the financial information prior to the Merger relate solely to Sonnet. Subsequent to the Merger, the consolidated financial statements relate to the consolidated entities of the Company. See Note 3 for additional discussion of the Merger.

Notes to Consolidated Financial Statements
Acquisition of Relief
In August 2019, the Company executed a Share Exchange Agreement with Relief Therapeutics Holdings SA (“Relief Holdings”), to acquire the outstanding shares of Relief Therapeutics SA (“Relief”), a wholly owned subsidiary of Relief Holdings, in order to further develop Relief’s asset, atexakin alfa, together with its proprietary experimental drugs. The acquisition of Relief was completed on April 1, 2020. See Note 4 for further discussion of the acquisition.
Global pandemic - Covid-19
On March 10, 2020, the World Health Organization characterized the novel COVID-19 virus as a global pandemic. There is significant uncertainty as to the likely effects of this disease which may, among other things, materially impact the Company’s planned clinical trials. This pandemic or outbreak could result in difficulty securing clinical trial site locations, clinical research organizations (“CROs”), and/or trial monitors and other critical vendors and consultants supporting the trial. In addition, outbreaks or the perception of an outbreak near a clinical trial site location could impact the Company’s ability to enroll patients. These situations, or others associated with Covid-19, could cause delays in the Company’s clinical trial plans and could increase expected costs, all of which could have a material adverse effect on the Company’s business and its financial condition. In particular, manufacturing of our pipeline products (other than SON-1010) has been delayed by COVID-19 related supply chain issues, specifically supply of raw materials, including media, resins, and analytical kits, compounded by international shipping delays. Although we do not have perfect visibility into a resolution of the supply chain issues, we anticipate delays of approximately one quarter to our programs for these products. Other than the foregoing, at the current time, the Company is unable to quantify the potential effects of this pandemic on its future operations.
The Company has incurred recurring losses and negative cash flows from operations activities since inception and it expects to generate losses from operations for the foreseeable future primarily due to research and development costs for its potential product candidates. The Company believes its cash of $27.6 million at September 30, 2021 will fund the Company’s projected operations into August 2022. Substantial additional financing will be needed by the Company to fund its operations. These factors raise substantial doubt about the Company’s ability to continue as a going concern. The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.
In May 2021, the Company entered into a license agreement with New Life Therapeutics PTE, LTD. Under the terms of the agreement, the Company has received $1.0 million in payments and has the potential to earn up to $20.0 million in milestone payments, as well as additional royalty payments (see Note 9).
The Company plans to secure additional capital in the future through equity or debt financings, partnerships, collaborations, or other sources to carry out the Company’s planned development activities. If additional capital is not available when required, the Company may need to delay or curtail its operations until such funding is received. Various internal and external factors will affect whether and when the Company’s product candidates become approved for marketing and successful commercialization. The regulatory approval and market acceptance of the Company’s products candidates, length of time and cost of developing and commercializing these product candidates and/or failure of them at any stage of the approval process will materially affect the Company’s financial condition and future operations.
