Clinical Trial Summary
This study is a prospective, randomized, open-label, multi-center trial. The primary
objective of the study is to assess whether XZK 1200mg/d, compared to atorvastatin 20mg/d,
has a favorable impact on HbA1c levels at 24 weeks of treatment in dyslipidemia patients with
prediabetes
Description:
Up to now, there is no published RCTs to compare the impact of XZK and statins on glucose
metabolism in Prediabetes with dyslipidemia. However, systematic reviews of several large
observational studies have recently found statin treatment is associated with a modest
increase in HbA1c in patients with T2DM. In these patients, the mean difference of HbA1c
increased by 0.17% (95% CI 0.07, 0.27) compared with the blanking control group[7]. For
instance, Atorvastatin 20mg is widely used medium intensity statin in clinical practice, but
a cohort study based on a database of Korea populations reported that the use of low dose
Atorvastatin 10-20mg tended to be a risk factor for onset diabetes (NODM) in Asians[8].
Meanwhile, a small RCT reported that HbA1c level was increased from 6.1% to 6.5% after
Atorvastatin 20mg/d treatment for 2 months[9]. The long-term administration of statins might
increase the risk of NODM approximately 10%-12%[10]. In short, a diabetogenic role of statins
has been demonstrated both from randomized trials and meta-analyses, and risk factors include
high dose, prolonged exposure, old age, prediabetic state and metabolic syndrome[11, 12]. In
consideration of prediabetes, including IFG, IGT, or A1C 5.7-6.4%, will be further increased
the risk of development diabetes mellitus, and the prevalence was 35.7% in China, we choose
the patients in Prediabetes with dyslipidemia in our study[4].
XZK, a partially purified red yeast rice (RYR) under controlled pharmaceutical manufacturing
conditions, contains a family of naturally occurring statins (monacolins)-most prominently
monacolin K, which is identical to the lipid- lowering therapy lovastatin (Mevacor)[13]. In a
meta-analysis, after compared the XZK treatment group showed significant lowering LDL-C
effect compared with basic therapy groups. [14] Xuezhikang in the China Coronary Secondary
Prevention Study trial(CCSPS) has shown that XZK significantly reduced the levels of TC, TG
and LDL-C and increased that of HDL-C in patients with hyperlipidemia after 1200mg/d
treatment for 8 weeks, among which TC decreased by 23.0%[15]. Furthermore, a retrospective
cohort study that used Taiwan's National Health Insurance data on 34,504 persons with a RYR
prescription in 2010-2014, found that a lower risk of incident diabetes when compared to
lovastatin cohort (HR:0.46, 95% CI 0.43-0.50)[16]. Why XZK can lower the risk of incident
diabetes compared to other statins? A variety of mechanisms have been elucidated. As main
components in XZK, n-3 polyunsaturated fatty acid(PUFAs) can regulate the activity of key
transcription factors to regulate gene expression in lipid metabolism and improve insulin
sensitivity of type 2 diabetes mellitus to prevent diabetic complications. Six weeks of
supplementation with n-3 PUFAs reduced the postprandial decrease in macrovascular function
and meanwhile improved postprandial microvascular function[17]. Moreover, it was reported
that magnesium deficiency can lead to the reduction of insulin sensitivity and affect the
stability of glucose metabolism. Thus, increasing the intake of magnesium plays an important
role in the prevention of noninsulin- dependent diabetes mellitus and its complications.
Moreover, selenium reduces the production of oxygen free radicals in the body by glutathione
peroxidase to prevent further oxidative damage in the body and the insulin A, B between the
two peptide chains for ensuring the complete molecule structure and function of insulin to
play a role in lowering blood glucose. In addition, selenium also has inhibitory effects on
complications of diabetes such as osteoporosis and retinopathy.
In addition, XZK has been proved to contain multiple active ingredients which leads to unique
MOA and multiple benefits[13]. It is composed of 13 kinds of natural statins, unsaturated
fatty acids, ergosterol, amino acids, flavonoids, alkaloid, trace elements, and other
substances, and thus could be regarded as a natural lipid lowering polypill[14]. All the
above-mentioned components might be involved in the mechanism of XZK to multiple benefits
such as antiatherosclerosis, liver protection, anticancer, neural regulation and protection,
and kidney protection effects[13]. Previous animal and cell experiments have shown that XZK
can also activate the PPARα pathway and up-regulate apolipoprotein A5 (apolipoprotein A5 is
the key regulator of TG metabolism) to achieve higher TG reduction when it reduces LDL-C by
the same extent as simvastatin[18]. It is speculated that non-statin elements within XZK may
play a synergistic role in regulating blood lipids and inhibiting the synthesis of
triglycerides. The China Coronary Secondary Prevention Study (CCSPS) and other clinical
studies confirmed that XZK capsules reduce lipid and significantly reduce the overall
mortality of patients with coronary heart disease, the incidence of cardiovascular events.
According to Chinese guidelines for the management of dyslipidemia in adults of 2016
revision, XZK amongst other statins are recommended for the first-line treatment of
cholesterol controlling. Meanwhile, XZK 1200mg/d and Atorvastatin 20mg/d are medium intensity
statins recommended in guideline[3]. therefore, we choose Atorvastatin 20mg/d as control drug
in our research.
Physicians faced with a dyslipidemia patient with prediabetes often use statins therapy due
to perceived efficacy. However, XZK is a promising option in this patient group due to their
significantly lower risk of dys-glycaemia without compromising efficacy for lowering lipids
in hyperlipidemia. Establishing comparable recurrent NODM rates in individuals with previous
Prediabetes state would result in superior DM prevention for these patients.
