There are about 36818 clinical studies being (or have been) conducted in China. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The objective of this study was to investigate the efficacy and safety of dydrogesterone in the long-term management of ovarian endometriosis cyst after surgery.
Low back pain (LBP) is the largest cause of morbidity in the world, and about 80% of Chinese people are affected in their lifetime. Although the prevalence of IDD gradually increases with age, IDD is very common among subjects under 30 years old. In addition to age, there are other factors, such as excessive or uneven mechanical load, obesity, genetics, nutrition, trauma and gender. In addition, it is not clear whether the heavy physical load associated with occupation is an important risk factor for IDD. Some studies have found that IDD is more common among athletes than the general population. Due to the complexity and multifactorial nature of IDD, its pathogenesis and risk factors are still unclear, which seriously hinders the rational stratification of LBP patients and limits the development of personalized treatment.
The purpose of this study is primarily to evaluate the effects of simultaneous administration of Tunodafil Hydrochloride Tablets with alcohol on blood pressure, pulse rate and pharmacokinetics in healthy Chinese male participants.
This study is a non blind, randomized controlled study, whose hypothesis was that chest wall/whole breast combined regional lymph node radiotherapy can improve the 5-year disease-free survival rate of clinical high-risk pN0 breast cancer patients.
Polycystic ovary syndrome (PCOS) is a common reproductive disease associated with endocrine and metabolic disorders. Some studies have shown that Chinese herbal medicine is beneficial for PCOS, but the efficacy of Chinese herbal medicine in the treatment of PCOS is not clear, because the quantity of pre-clinical data was limited and the quality of clinical evidence was variable. Therefore, this randomized double-blind placebo-controlled trial aim to evaluate the efficacy of Chinese herbal medicine (Bushen Huatan Decoction) in women with PCOS.

This is a Phase 3, parallel group, placebo-controlled, double-blind, confirmatory study in patients with CINDU, with an optional Open-label Extension (OLE). The purpose of the core period (52 weeks of treatment) of this study is to evaluate the efficacy, safety, and tolerability of remibrutinib (LOU064) vs. placebo in adults suffering from CINDU inadequately controlled by H1-antihistamines (H1-AHs). The purpose of the OLE period is to collect long-term efficacy, safety, and tolerability data on remibrutinib in participants after having completed the Core period
Post-stroke cognitive impairment (PSCI) refers to a clinical syndrome characterized by cognitive impairment that occurs after a stroke event and persists for at least 24 weeks. Due to the early recovery of conditions such as delirium and transient cognitive impairment after stroke, the diagnosis of PSCI often requires cognitive assessment at 12 to 24 weeks post-stroke to determine the severity of cognitive impairment. It can be classified according to the severity of cognitive impairment as post-stroke cognitive impairment no dementia (PSCIND) and post-stroke dementia (PSD). Recent large international cohort studies have reported an incidence rate of PSCI ranging from 24% to 53.4%, and patients with PSCI have a significantly higher mortality rate compared to those without cognitive impairment. Guidelines such as American Heart Association/American Society of Anesthesiologists (AHA/ASA) and the Chinese "Expert Consensus on the Management of Post-Stroke Cognitive Impairment" propose integrating cognitive impairment and stroke intervention strategies. Early comprehensive intervention and treatment for high-risk individuals after stroke, aiming to delay or prevent the progression from PSCIND to PSD, are the primary goals in the current treatment of PSCI. However, there is currently a lack of large randomized controlled trials (RCTs) for PSCI, and research is still needed to determine whether cognitive-enhancing drugs can reduce the risk of PSCI occurrence and improve outcomes and prognosis for PSCI patients. A randomized, double-blind, multicenter clinical study involving 281 non-dementia vascular cognitive impairment (VCI) patients showed that the overall cognitive scores of patients treated with donepezil for 24 weeks significantly improved compared to the placebo group. The aim of this study is to evaluate the effectiveness of donepezil in the treatment of post-stroke cognitive impairment. It will be a multicenter, randomized, double-blind, placebo-controlled trial with a 48-week treatment duration. The study will observe the difference in PSCI incidence rate between the donepezil treatment group and the conventional stroke treatment group at 24 weeks and evaluate the improvement in post-stroke cognitive impairment after 6 months of donepezil treatment compared to conventional treatment. This study will be conducted in two stages: the first stage (0-24 weeks) aims to assess whether donepezil can reduce the risk of PSCI occurrence and will be a multicenter, randomized, double-blind, placebo-controlled study. The second stage (24-48 weeks) aims to evaluate whether donepezil can improve the prognosis of PSCI patients and will also be a multicenter, randomized, double-blind, placebo-controlled study.
To explore the effectiveness and safety of rTMS intervention with different targets in the left prefrontal cortex defined using the pBFS method, in adult patients with moderate and severe depressive disorder. Second, investigate the neural circuit that responds to the rTMS intervention using individualized brain image analysis, which may help to establish an effective target for the neuromodulation of patients with major depressive disorder.
