Sonnet is pleased to provide the following updates on its pipeline assets:
SON-1010 (IL12-FHAB): On February 1st, Sonnet announced that it had successfully completed a non-human primate (NHP), non-GLP repeat-dose toxicology study of SON-1010. The drug candidate was well tolerated at doses far exceeding levels expected in future human clinical trials, without producing detectable cytokine imbalances. SON-1010 demonstrated an enhanced pharmacokinetic (PK) profile as compared to recombinant IL-12. Analysis of interferon-γ levels, a key biomarker of antitumor activity, continued to suggest potent pharmacodynamic (PD) effects in the monkeys studied.
On May 10th, Sonnet announced the completion of a successful GLP repeat dose toxicology study of SON-1010 in NHPs. The No Observed Adverse Event Level (NOAEL) following repeated administration was more than 50 times the anticipated equivalent human clinical dose in NHPs with no evidence of cytokine release syndrome.PK analysis of serum samples confirmed an enhanced profile of IL12-FHAB over recombinant human IL-12, with a half-life around 40 hours in NHPs. A significant increase in interferon-γ, a key pleiotropic cytokine associated with anti-tumor mechanisms, was observed following dosing with IL12-FHAB.
An IND for SON-1010 has been submitted to the FDA and additional product stability data will be submitted in the first quarter of 2022. Subject to FDA approval, we expect to initiate a US clinical trial in oncology patients with solid tumors during the first half of 2022. We are also preparing to initiate an Australian clinical trial in healthy volunteers during the first half of 2022 to study the compound's PK and PD, in preparation for potential combination studies.
SON-080 (low-dose IL-6): On January 25th, Sonnet announced that Sonnet CH, a wholly owned subsidiary of Sonnet headquartered in Switzerland, had successfully completed a multiple dose NHP study of SON-080. The toxicology study demonstrated a wide safety margin with no adverse effects observed in male or female cynomolgus monkeys at the doses tested. 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. Pursuant to the license agreement the Company entered with New Life Therapeutics Pte., Ltd 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 efficacy study in the second half of 2022.
SON-1210 (IL12-FHAB-IL15): SON-1210, Sonnet's first bispecific candidate, is undergoing cell line and process development activities. Early development materials were used in a mouse tumor model study, and additional biodistribution studies are planned. This work will inform the Company's decision about dosing in a forthcoming NHP study, expected to be initiated in the first half of 2022. Scale up and cGMP manufacturing is scheduled to be completed in the first half of 2022, which will support the GLP NHP study, as well as First-In-Human (FIH) studies. Sonnet expects to initiate the regulatory authorization process for solid tumor indications in the second half of 2022.
SON-1410(IL18-FHAB-IL12): On August 30th, Sonnet announced that it had selected a novel development candidate after completing comparative studies in a mouse melanoma model. The candidate represents Sonnet's second bispecific compound integrating interleukin 12 (IL-12) with the company's FHAB platform. The target indications for SON-1410 will be melanoma and renal cancers.
