Item
8.01. Other Events.
On March 29,
2021, the Company announced a business update on its ongoing programs, as summarized below:
|
●
|
SON -1010
(FHAB-IL12): The Company has completed nonhuman primate (“NHP”) GLP toxicity studies with SON-1010
and is awaiting data to prepare an IND submission, while working in parallel to initiate clinical trials during the second
half of this year. Prior to IND submission, the Company will initiate pre-IND interactions with the U.S. Food and Drug Administration,
which are expected during the second quarter, and will work to finalize the first-in-human protocol, along with selecting
a contract research organization (“CRO”) to perform the studies. CMC activities are on schedule to deliver GMP
material prior to the IND filing.
|
|
|
|
|
●
|
SON-080
(Fully Human IL-6) – Chemotherapy Induced Peripheral Neuropath (“CIPN”): With successful
GLP toxicity studies completed, the CMC manufacturing is well underway, and product is expected to be available for a clinical
trial commencing during the second half of this year. Plans have been initiated to complete the study design protocol
for a Phase 1b/2a study, as well as the completion of diligence and selection of a CRO.
|
|
|
|
|
●
|
SON-081
(Fully Human IL-6) – Diabetic Peripheral Neuropathy (“DPN”): The Company anticipates completing the
partnership deal in South East Asia during April 2021 that the Company expects will position New Life Therapeutics (“NLT”)
to fund and progress the asset forward into a Phase 1b/2a clinical trial. NLT has elected to focus on the acceleration
of the development of low dose IL-6 for DPN at this time, and to hold an option to the CIPN indication for several months
following the execution of a definitive agreement. The Company anticipates that clinical trial initiation will
occur during the second half of this year. The Company has recently obtained positive initial comparability data from the
new batch being manufactured using an updated process and awaits final study completion and reports of product comparability,
prior to IND filing.
|
|
|
|
|
●
|
SON-1210
(IL12-FHAB-IL15): The Company’s first bispecific candidate is undergoing cell line and process development. The
Company has engaged a novel intensified perfusion manufacturing process to generate clinical grade material and expects completion
of NHP studies in the second half of this year with an IND submission during the first half of 2022.
|
|
|
|
|
●
|
SON-2014
(GMcSF-FHAB-IL18): In addition to GMcSF-FHAB-IL18, the Company has manufactured bi-specific
preclinical constructs of 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.
|
Upon
completion of the preclinical efficacy evaluation in the second quarter of this year, the Company intends to initiate commercial
cell line development necessary for future clinical trials. An IND submission for SON-2014 is currently targeted for the second
half of 2022.
|
●
|
SON-3015
(Anti-IL6-FHAB-Anti-TGFβ): The Company is in the discovery phase of SON-3015 development and is currently
panning the candidate for binding and stability, after which the preclinical bispecific product will be evaluated in a mice
model, expected during the second half of 2021. The Company is planning to initiate commercial cell line development in the
first quarter of 2022.
|
|
|
|
|
●
|
INTELLECTUAL
PROPERTY: The Company has received Notice of Allowance from the United States Patent and Trademark Office for its first

first half of 2021.
