On December 18, 2024, Zhikang Hongyi announced the highly selective
endothelin receptor A (ETA) small molecule antagonist SC0062 project, one of its
core pipelines. In a 2-SUCCEED clinical phase II trial for chronic kidney
disease (CKD) with proteinuria, the results of its diabetes nephropathy (DKD)
cohort study reached the main clinical endpoint of 12 weeks - this is another
major milestone in the clinical development of SC0062 after the previously
announced IgA nephropathy cohort study results reached various clinical
endpoints.
The experimental results indicate that:
In terms of effectiveness, compared with the placebo group, the high-dose
group (20mg) of SC0062 can significantly reduce albuminuria, and the results
have clinical and statistical significance;
Safety: SC0062 showed good safety. Compared with the placebo group, there
was no increased risk of water and sodium retention. In this clinical trial, the
vast majority of DKD subjects received SGLT2 inhibitors and RAAS inhibitors as
basic treatment, while SC0062 was used alone and in combination, demonstrating
good safety in the study.
These latest results, including more data from 24 weeks, will be announced
at an international medical academic conference.
2-SUCCEED is a multicenter, randomized, double-blind, placebo controlled,
dose exploration, 2-cohort (IgA nephropathy cohort and diabetes nephropathy
cohort) phase II clinical trial designed to evaluate the efficacy and safety of
SC0062 capsule in chronic kidney disease patients with proteinuria.
Previously, SC0062 had reached all clinical endpoints in IgA nephropathy
trials. Based on its outstanding clinical manifestations, SC0062 has been
included in the breakthrough treatment list by CDE for the treatment of IgA
nephropathy with proteinuria.
This SC0062 reached the main clinical end point in the diabetes nephropathy
test, further indicating that it has a significant and continuous effect of
reducing proteinuria in a variety of chronic kidney diseases (CKD) with
proteinuria, as well as outstanding safety advantages, which once again proves
the potential of its best in class (BIC) molecule.

After reviewing the above research results, it is stated that:
It's nice to know that SC0062 has achieved positive results in the diabetes nephropathy trial queue, especially that no risk of water and sodium retention caused by SC0062 was found in the study, which will be a major breakthrough in drug development of ETA antagonists.
Co founder of Zhikang Hongyi
Dr. Wang Yiyi, the CEO, stated:
SC0062 is a new ETA antagonist molecule developed by Zhikang Hongyi, which
has demonstrated numerous efficacy and safety advantages in preclinical and
early clinical trials.
We are pleased to witness the superior effect of SC0062 on reducing
proteinuria in patients with diabetes nephropathy. The safety of SC0062 molecule
in patients with diabetes nephropathy has greatly enhanced the confidence of
SC0062 in developing chronic kidney disease (CKD). At present, Zhikang Hongyi is
making every effort to promote the registration of clinical trials in the field
of SC0062 kidney disease, in order to benefit the global population of chronic
kidney disease as soon as possible.
Based on the potential huge clinical advantages and market prospects, the
company has launched a phase III clinical study called "SUCCESS-1" for IgA
nephropathy, as well as an international multicenter phase III clinical study
called "SUCCESS-2" for chronic kidney disease (CKD). The company will continue
to fully utilize its excellent clinical development capabilities and work
together with top researchers around the world to promote the global clinical
progress of this potential best in class molecule, benefiting patients worldwide
as soon as possible.
Regarding SC0062
SC0062 is one of the top three endothelin receptor A (ETA) small molecule
antagonists for the treatment of chronic kidney disease that have entered
clinical trials worldwide. It is a highly promising Best in Class drug. SC0062
has undergone a novel molecular design for chronic kidney disease, with unique
ETA high selectivity, aiming to further enhance drug safety while ensuring
efficacy.
Preclinical studies have shown that SC0062 has good activity and can
effectively improve pathological scores in acute kidney injury and chronic
kidney disease models. In the completed clinical phase I study, SC0062 showed
good safety, tolerance and pharmacokinetics characteristics, and no side effects
such as water and sodium retention were found.
SC0062 is currently carrying out a phase II clinical study (2-SUCCEED) on
chronic kidney disease with proteinuria. This study is a multicenter,
randomized, double-blind, placebo controlled, dose range exploration, and
2-cohort (IgA nephropathy cohort and diabetes nephropathy cohort) clinical study
designed to evaluate the effectiveness and safety of SC0062 capsule in chronic
kidney disease patients with proteinuria. Professor Chen Jianghua, director of
the Kidney Disease Center of the First Affiliated Hospital of Zhejiang
University Medical College and former chairman of the Renal Branch of the
Chinese Medical Association, served as the main investigator, and has been
carried out simultaneously in more than 40 clinical institutions nationwide.
The 2-SUCCEED study has completed the enrollment of all subjects in two
cohorts. The IgA nephropathy trial has reached the clinical primary endpoint at
12 weeks and the secondary endpoint at 24 weeks. Some of the research results
have been published in the top nephrology journal JASN. Another queue of DKD
trials has reached the 12 week clinical primary endpoint, and 24 week data is
currently being collected and organized, with data analysis expected to be
completed in the near future.
SC0062 has currently initiated two Phase III clinical studies, one for IgA
nephropathy (named "SUCCESS-1") and the other for chronic kidney disease (named
"SUCCESS-2").
