The safety and efficacy of CKD-497 in patients with acute upper respiratory tract infection and bronchitis symptoms: a multicenter, double-blind, double-dummy, randomized, controlled, phase II clinical trial.

ABSTRACT:

Background

Acute upper respiratory tract infection (AURI) together with acute bronchitis is the most common illness worldwide. Botanical medicines used as expectorants and antitussives have proven to be effective while also having excellent safety margins. We aimed at evaluating the efficacy and safety of a new botanical drug, CKD-497, in patients with AURI and acute bronchitis.

Methods

In this phase 2 study, 225 patients were enrolled and randomly assigned to one of four treatment groups: placebo (n=55), Synatura^® (n=49), CKD-497 200 mg (n=68), or CKD-497 300 mg (n=53). The study drugs were administered three times daily over the course of 7 days. Primary endpoint was the change in the bronchitis severity score (BSS) from baseline to day 7. Secondary endpoint was evaluated based on clinical response rates on days 4 and 7. A safety analysis was also performed.

Results

Between baseline and day 7, the mean BSS scores decreased significantly in each group (P<0.001): -4.04±1.85, -4.31±1.47, -4.09±1.48, and -4.28±1.69. However, neither the CKD-497 nor Synatura^® group showed any significant effect on the difference in BSS change (P=0.75). The rate of clinical response was higher in the CKD-497 300 mg group as compared to the placebo only on day 4 (36% vs. 18%; P<0.05) and those having more severe bronchitis (phlegm score ≥3) showed a significant reduction of total BSS in the Synatura^® and CKD-497 groups (P=0.042). No significant adverse events were observed in either of the CKD-497 groups.

Conclusions

CKD-497 and even the positive control drug had no significant effect on BSS change in this phase 2 clinical trial. However, CKD-497 300 mg had a mild but significant clinical improvement in early bronchitis patients with more severe phlegm. Considering both efficacy and safety, a future study using 300 mg of CKD-497 with a shorter-term endpoint is warranted in patients with more severe bronchitis symptoms.

Project description:BackgroundEchinacea has antiviral activity against influenza viruses in vitro and has traditionally been used for treatment of colds and flu.ObjectivesThis randomized, double-blind, double-dummy, multicenter, controlled clinical trial compared a new echinacea formulation with the neuraminidase inhibitor oseltamivir, the gold standard treatment for influenza.MethodsFollowing informed consent, 473 patients with early influenza symptoms (≤48 hours) were recruited in primary care in the Czech Republic and randomized to either 5 days of oseltamivir followed by 5 days of placebo, or 10 days of an Echinacea purpurea-based formulation called Echinaforce Hotdrink (A. Vogel Bioforce AG, Roggwil, Switzerland). The proportion of recovered patients (influenza symptoms rated as absent or mild in the evening) was analyzed for noninferiority between treatment groups using a generalized Wilcoxon test with significance level α = 0.05 (2-sided) and using a CI approach in the per-protocol sample.ResultsRecovery from illness was comparable in the 2 treatment groups at 1.5% versus 4.1% after 1 day, 50.2% versus 48.8% after 5 days, and 90.1% versus 84.8% after 10 days of treatment with Echinaforce Hotdrink and oseltamivir, respectively. Noninferiority was demonstrated for each day and overall (95% CI, 0.487-0.5265 by generalized Wilcoxon test). Very similar results were obtained in the group with virologically confirmed influenza virus infections and in a retrospective analysis during the peak influenza period. The incidence of complications was lower with Echinaforce Hotdrink than with oseltamivir (2.46% vs 6.45%; P = 0.076) and fewer adverse events (particularly nausea and vomiting) were observed with Echinaforce Hotdrink.ConclusionsEchinaforce Hotdrink is as effective as oseltamivir in the early treatment of clinically diagnosed and virologically confirmed influenza virus infections with a reduced risk of complications and adverse events. It appears to be an attractive treatment option, particularly suitable for self-care. Clinical trial identifier: Eudra-CT: 2010-021571-88. (Curr Ther Res Clin Exp. 2015; 77:66-72).

Project description:BackgroundTenofovir disoproxil fumarate (TDF) is a prodrug of a nucleotide analogue. As an antiviral drug, TDF has been proposed in the first-line treatment of chronic hepatitis B (CHB). Qingzhong, a brand name of TDF, commercialized by Jiangsu Chia-tai Tianqing Pharmaceutical Co Ltd., and Viread, another brand name of TDF, commercialized by GlaxoSmithKline, have both been approved by the State Food and Drug Administration, China.AimTo investigate the efficacy and safety of the two TDF agents in the treatment of Chinese CHB patients.MethodsThis trial was registered at ClinicalTrials.gov with the identifier number of NCT02287857. A total of 330 Chinese CHB patients, among which 232 were hepatitis B e antigen (HBeAg)-positive, were included in this 5-year-long, multicenter, double-blinded, double-dummy, randomized-controlled, non-inferiority phase III trial. The participants were initially randomized into two groups: Group A (n = 161), in which the participants received 300 mg Qingzhong once a day for 48 wk; and Group B, in which the participants received 300 mg Viread once a day for 48 wk. Starting from week 49, all the participants in Groups A and B received 300 mg Qingzhong once a day until the 96th week. In this study, the primary endpoint was the decrease in plasma level of hepatitis B virus (HBV) DNA at the 96th week, while the secondary endpoints were suppression of HBV replication, alanine aminotransferase (ALT) normalization, HBeAg loss, and HBeAg seroconversion rates.ResultsFor the participants with HBeAg-positive CHB, the decrease in mean HBV DNA level relative to the baseline value was comparable between Groups A and B (5.77 vs 5.73 log10 IU/mL, P > 0.05) at the 96th week. In addition, similar percentages of HBeAg-positive participants in the two groups exhibited undetectable levels of HBV DNA, HBeAg loss, and HBeAg seroconversion (71.05% vs 77.97%, 31.00% vs 27.27%, and 20.22% vs 15.79%, respectively, in Group A vs Group B; P > 0.05). For the participants with HBeAg-negative CHB, the decrease in mean HBV DNA level relative to the baseline value was also comparable between Groups A and B (4.46 vs 4.70 log10 IU/mL, P > 0.05) at the 96th week. In addition, similar percentages of HBeAg-negative participants in the two groups exhibited undetectable levels of HBV DNA (87.23% vs 94.12% in Group A vs Group B, respectively; P > 0.05). Finally, similar percentages of CHB patients (HBeAg-positive or HBeAg-negative) in the two groups exhibited normalization of ALT (80.14% vs 84.57% in Group A vs Group B, respectively; P > 0.05), and similar incidences of adverse events were observed (106 vs 104 in Group A vs Group B, respectively; P > 0.05).ConclusionBoth Qingzhong and Viread are effective and safe in the treatment of Chinese CHB patients according to the results of our clinical trial.

Project description:BackgroundAcute uncomplicated lower urinary tract infection (UTI) is one of the most common bacterial infections. Patients usually present with dysuria, urinary urgency, urinary frequency, and suprapubic pain or tenderness. Approximately 150 million people are diagnosed with UTI each year worldwide. The high recurrence rate of lower UTI is a common problem of clinical treatment. The misuse of antibiotics has led to the emergence of a number of resistant bacterial strains. Thus, traditional Chinese medicine is considered as an alternative option for treating acute uncomplicated lower UTI. Thus, this study aims to evaluate the efficacy and safety of Sanjin tablets (SJT) for the treatment of acute uncomplicated lower UTI, explore whether SJT can reduce or substitute the use of antibiotics, and reduce the recurrence rate in the treatment of acute uncomplicated lower UTI.Methods/designIn this study, a randomized, double-blind, double-dummy, parallel control of positive drug, multicenter clinical study will be established. A total of 252 patients with acute uncomplicated lower UTI (syndrome of dampness-heat in the lower jiao) will be randomly allocated in the ratio of 1:1:1 to three groups: experimental group; control group 1; and control group 2. The experimental group receives Sanjin tablets plus levofloxacin tablets (LT) placebo; the control group 1 receives LT plus SJT placebo; and the control group 2 receives SJT plus LT on the first five days, SJT plus LT placebo on the last two days. Each group will be treated for seven days and followed-up 1-2 times. The primary outcome measures of effective rate and recurrence rate are symptoms. Secondary outcome measures of effective rate and recurrence rate are the urine leukocytes, bacteriology examination, and safety assessment. Outcomes will be assessed at baseline and after treatment.DiscussionThis study protocol will provide the research data of efficacy and safety of SJT for the treatment of acute uncomplicated lower UTI. The first aim is to determine whether Sanjin tablets can reduce the use of antibiotics; the second aim is to determine whether Sanjin tablets can substitute the use of antibiotics. The recurrence rate will be assessed after cured to determine whether SJT can reduce the recurrence rate. The results of this study will improve the rational use of drugs, especially the rational application of antibiotics. It will also enable safety evaluation from laboratory indices and adverse events, which will provide reliable evidence for clinical treatment.Trial registrationClinicalTrials.gov, NCT03658291 .

Project description:Background: Wuhu Oral Liquid (WHOL) is a modified preparation derived from the famous Wuhu Powder, which has a long history of use in treating traumatic injuries. This preparation has anti-inflammatory and analgesic properties and accelerates recovery following acute soft tissue injuries. Aims: To evaluate the efficacy and safety of WHOL in treating acute soft tissue injury associated with qi stagnation and blood stasis syndrome and to provide a basis for applying for the protection of varieties of Chinese medicine for WHOL. Methods: This study was a randomized, controlled, double-blind, multicenter clinical trial in which Fufang Shang Tong Capsule (FFSTC) was selected as the control drug. A total of 480 subjects with acute soft tissue injury associated with qi stagnation and blood stasis syndrome were randomly divided into a test and control group in a 3:1 ratio. The duration of drug treatment was 10 days. The primary outcome was Visual Analogue Scale (VAS) score for pain (including pain at rest and pain on activity). Secondary outcomes included the disappearance time of the pain at rest and on activity; the curative effect of TCM syndrome and improvement in the individual symptoms of TCM (swelling, ecchymosis, and dysfunction); and changes in C-reactive protein (CRP) and interleukin-6 (IL-6) levels. Safety was assessed using vital signs, laboratory examinations, electrocardiograms, and physical examinations. Results: Patient compliance was satisfactory in both groups (all between 80% and 120%). After 4 days of treatment, the WHOL group was superior to the FFSTC group in decreasing the VAS scores for pain at rest (-1.88 ± 1.13 vs. -1.60 ± 0.93, p < 0.05) and on activity (-2.16 ± 1.18 vs. -1.80 ± 1.07, p < 0.05). After 7 days of treatment, the WHOL group was superior to the FFSTC group in decreasing the VAS scores for pain on activity (-3.87 ± 1.60 vs. -3.35 ± 1.30, p < 0.01) and improving swelling (cure rate: 60.4% vs. 46.2%, p < 0.05; obvious effective rate: 60.7% vs. 47.0%, p < 0.05). After 10 days of treatment, the WHOL group was superior to the FFSTC group in decreasing the levels of CRP (-0.13 ± 2.85 vs. 0.25 ± 2.09, p < 0.05) and improving the TCM syndrome (cure rate: 44.1% vs. 30.8%, p < 0.05) and swelling (cure rate: 75.6% vs. 67.5%, p < 0.01; obvious effective rate: 75.6% vs. 68.4%, p < 0.05; effective rate: 77.0% vs. 71.8%, p < 0.05). The disappearance time of pain at rest was 8 days in both groups and 9 days on activity in both groups. In addition, there was no statistical difference between the incidence of adverse events (4.5% vs. 2.6%, p > 0.05) and adverse reactions (0.3% vs. 0%, p > 0.05) between the WHOL group and the FFSTC group. No serious adverse events occurred in either group, and no subjects were withdrawn because of adverse events. Conclusion: WHOL relieves the symptoms caused by acute soft tissue injury associated with qi stagnation and blood stasis syndrome more rapidly than FFSTC, and it is effective and safe in the treatment of acute soft tissue injury. Future studies still need a larger sample size to verify its efficacy and safety. Clinical Trial Registration: https:// www.chictr.org.cn/showproj.html?proj=149531, Identifier ChiCTR2200056411.

Project description:ObjectiveTo investigate the effectiveness of a Chinese patent medicine, Jintiange capsules with the main component of artificial tiger bone powder, combined with alfacalcidol on muscle strength and balance of the lower extremities in patients with primary osteoporosis.DesignA randomized, double-blind, double-dummy, positive-controlled, multicenter clinical trial.Subjects and methodsA total of 400 patients diagnosed with primary osteoporosis or osteopenia were recruited and randomized into the Jintiange or control groups. During the 52-week treatment, the participants in the Jintiange group were treated with Jintiange capsules (1.2 g each time, 3 times per day) and calcium carbonate simulant, while those in the control group were treated with calcium carbonate (element calcium 0.3 g, twice a day) and a Jintiange capsule simulant. Alfacalcidol (0.25 μg/d) was applied in both groups. The timed up and go test (TUG), chair rising test (CRT), and tandem gait test (TGT) were performed to evaluate balance, muscle strength and fall risk of the participants.ResultsThere were 154 participants in the Jintiange group, and 157 participants in the control group were included in the per-protocol set. Comparing the data at week 52 from those at baseline, the TUG time decreased from 9.60 ± 2.25 s to 8.53 ± 2.06 s (p < 0.001) in the Jintiange group and decreased from 9.50 ± 1.91 s to 9.11 ± 1.95 s (p < 0.001) in the control group; the CRT time decreased from 11.49 ± 4.05 s to 8.57 ± 2.13 s (p < 0.001) and 11.17 ± 3.21 s to 9.74 ± 1.98 s (p < 0.001) in the Jintiange and control groups, respectively; the number of correct steps in the TGT increased significantly in both the control (7.40 ± 1.27 vs. 7.69 ± 0.87, p < 0.01) and Jintiange groups (7.21 ± 1.58 vs. 7.60 ± 1.12, p < 0.001). At the end of the study, the TUG and CRT results in the Jintiange group were superior to those in the control group (all p value < 0.05), while no obvious difference was found in the TGT between the two groups. At week 52, the high fall risk proportions in the Jintiange group were significantly lower than those in the control group according to TUG (3.25% vs. 9.55%, p = 0.023) and CRT (20.78% vs. 33.76%, p = 0.01).ConclusionJintiange capsules combined with alfacalcidol can effectively improve muscle strength and the balance of the lower extremities and reduce fall risk in patients with primary osteoporosis/osteopenia.The translational potential of this articleArtificial tiger bone powder, a traditional Chinese patent medicine, can improve muscle strength and balance and reduce fall risks effectively among patients with primary osteoporosis. It might be a therapeutic option for osteoporosis individuals combined with sarcopenia to improve their muscle function.

Project description:ObjectiveTraditional Chinese medicine (TCM) has certain curative effect against acute gouty arthritis (AGA), but it lacks high-quality evidence-based studies. In this randomized controlled trial, we try to evaluate the clinical efficacy and safety of Qinpi Tongfeng Formula (QPTFF) in the treatment of AGA.MethodsOne hundred and fourteen patients with AGA (damp heat accumulation syndrome) who met the inclusion and exclusion criteria were randomly divided into treatment group and control group in a ratio of 1 : 1. Patients in the treatment group were treated with QPTFF, and patients in the control group were treated with diclofenac sodium sustained-release tablets for 7 days. The primary outcome measure was the change in visual analog scale (VAS) score for pain from the baseline to day 8. The secondary outcome measures were joint symptom score, TCM syndrome score, total effective rate, pain cure rate, complete pain relief time, patient satisfaction score, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and serum uric acid level. The safety outcome measures were routine blood test, urinalysis, liver function including alanine aminotransferase and aspartate aminotransferase, renal function including blood urea nitrogen and serum creatinine, and the rate of treatment-related adverse events (TRAEs).Results105 patients with 53 in the treatment group and 52 in the control group completed the 7-day treatment. There was no significant difference between two groups in demographic characteristics, VAS score for pain, joint symptom score, TCM syndrome score, ESR, CRP, and serum uric acid level before enrollment at baseline (based on both the full analysis set (FAS) and per protocol set (PPS), P > 0.05). The 95% confidence interval of the difference between the eighth and first VAS score for pain of the two groups was (-0.57, 0.42) in FAS and (-0.48, 0.47) in PPS. The lower bound of both FAS and PPS is greater than the bound value of -0.7. On day 8, there was no significant difference between the two groups in joint symptom score, TCM syndrome score, total effective rate, pain cure rate, complete pain relief time, patient satisfaction score, ESR, and CRP (FAS and PPS, P > 0.05). The serum uric acid level and TRAEs in the treatment group were significantly lower than those in the control group (FAS and PPS, P < 0.05).ConclusionsQPTFF could alleviate the symptoms of patients with AGA, which is not inferior to diclofenac sodium sustained-release tablets in analgesic. Moreover, QPTFF overmatches diclofenac sodium sustained-release tablets in decreasing serum uric acid level and TRAEs. Therefore, the results provide reliable foundation for QPTTF in the treatment of AGA. Trial Registration. This study protocol was registered in Chinese Clinical Trial Registry (registration number: ChiCTR2100050638).
