New Compounds

So many new compounds are now being introduced for the treatment of psychiatric disorders that it is difficult for the clinician to assess the accuracy of the claims made for them. If a form of therapy is one hundred per cent. effective in a disease which was previously one hundred per cent. fatal, for example vitamin B12 in pernicious anaemia, the question of a controlled trial does not arise. But even the manufacturers do not claim such a degree of effectiveness for drugs advocated for the treatment of mental illnesses, and in addition the natural course of such illnesses is very variable, so that it is essential that clinical trials of these drugs should be controlled. Foulds (1958) has reviewed British and American clinical trials of drugs in psychiatry during the years 1951 to 1956, and has shown that the less controlled a trial, the more likely it is to result in a favourable report on the drug being tested, presumably because of bias on the part of the clinician. Forrester (1958), however, on the basis of a completely uncontrolled trial of Stelazine on only twenty-five patients, concluded that “the amount of improvement in a few cases was not sufficient to encourage the further use of the drug”.

Abstract Background Low recruitment in clinical trials is a common and costly problem which undermines medical research. This study aimed to investigate the challenges faced in recruiting children and adolescents with obsessive-compulsive disorder and autism spectrum disorder for a randomized, double-blind, placebo-controlled clinical trial and to analyze reasons for non-participation. The trial was part of the EU FP7 project TACTICS (Translational Adolescent and Childhood Therapeutic Interventions in Compulsive Syndromes). Methods Demographic data on pre-screening patients were collected systematically, including documented reasons for non-participation. Findings were grouped according to content, and descriptive statistical analyses of the data were performed. Results In total, n = 173 patients were pre-screened for potential participation in the clinical trial. Of these, only five (2.9%) were eventually enrolled. The main reasons for non-inclusion were as follows: failure to meet all inclusion criteria/meeting one or more of the exclusion criteria (n = 73; 42.2%), no interest in the trial or trials in general (n = 40; 23.1%), and not wanting changes to current therapy/medication (n = 14; 8.1%). Conclusions The findings from this study add valuable information to the existing knowledge on reasons for low clinical trial recruitment rates in pediatric psychiatric populations. Low enrollment and high exclusion rates raise the question of whether such selective study populations are representative of clinical patient cohorts. Consequently, the generalizability of the results of such trials may be limited. The present findings will be useful in the development of improved recruitment strategies and may guide future research in establishing the measurement of representativeness to ensure enhanced external validity in psychopharmacological clinical trials in pediatric populations.

Poliomyelitis Vaccine

Global polio eradication requires both safe and effective vaccines, and safe production processes. Sabin oral poliomyelitis vaccine (OPV) strains can evolve to virulent viruses and result in poliomyelitis outbreaks, and conventional inactivated poliomyelitis vaccine (Salk-IPV) production includes accumulation of large stocks of neurovirulent wild polioviruses. Therefore, IPV based on attenuated OPV strains seems a viable option. To increase the global supply of affordable inactivated vaccine in the still not-polio free world we developed an IPV made from the Sabin strains–PoliovacSin. Clinical trials included participants 18–60 years of age. A phase I single-center, randomized, double-blind placebo-controlled clinical trial included 60 participants, who received one dose of PoliovacSin or Placebo. A phase II multicenter, randomized, double-blind, comparative clinical trial included 200 participants, who received one dose of PoliovacSin or Imovax Polio. All vaccinations were well tolerated, and PoliovacSin had a comparable safety profile to the Placebo or the reference Imovax Polio preparations. A significant increase in neutralizing antibody levels to polioviruses types 1–3 (Sabin and wild) was observed in PoliovacSin and Imovax Polio vaccinated groups. Therefore, clinical trials confirmed good tolerability, low reactogenicity, and high safety profile of the PoliovacSin and its pronounced immunogenic properties. The preparation was approved for clinical trials involving infants.

Objective.The randomized controlled trial was to evaluate the efficacy of topical Chinese herbal Zhangpi Ointment for hydroxyurea-induced leg ulcers in patients with myeloproliferative neoplasms.Patients and Methods.This single-center, prospective, randomized, open-label, controlled clinical trial conducted at Shanghai Ninth People’s Hospital enrolled 54 patients with hydroxyurea-induced leg ulcers. Patients were randomly assigned to the control group (n = 27) treated with chlorhexidine dressing or the intervention group (n = 27) treated with the Zhangpi Ointment. Finally, 26 patients in the control group and 23 patients in the intervention group completed 8 weeks of observation.Results.The rate of complete healing was 100% for the intervention group, which was significantly higher than that of the control group (96.15%) (P<0.05). Furthermore, the intervention group achieved a significantly higher rate of wound healing (95.56%) than the control group (69.02%) at week 4 (P<0.01). The intervention group took 34 ± 5 days to achieve complete healing while the control group took 41 ± 7 days (P< 0.01). Moreover, grade 3/4 side effects were observed in neither group.Conclusion.The Zhangpi Ointment is effective in promoting the healing of hydroxyurea-induced leg ulcers in patients with myeloproliferative neoplasms, providing a therapeutic option for a condition that is recalcitrant to conventional therapy.

6593 Background: Clinical cancer trials allow investigators to test the effectiveness and safety of new cancer drugs and treatments. Historically, fewer that 5% of cancer patients have participated in clinical trials. The purpose of this study was to assess attitudes, beliefs, and practical barriers to clinical trial recruitment. Methods: Women were recruited in the Herbert Irving Comprehensive Cancer Center while waiting for routine breast screening or for oncology care in connection with a diagnosis of breast cancer. The 29-item survey questionnaire covered demographic factors, prior cancer diagnosis or risk factors, past experience with clinical trials if any, willingness to participate in different types of trials, and attitudinal and practical barriers to participation. Results: Of 329 respondents, 48.9% were non- Hispanic white, 10.9% non-Hispanic black, 34.9% Hispanic, and 5.30% other/unknown. The mean age of participants was 52.5 (SD=12.1). Of 131 (39.8%) participants reporting that they had been asked to participate in clinical trial, 82 were white, 17 black and 32 Hispanic. Of those who enrolled, 64 were white, 14 were black, and 19 Hispanic. Of those asked to participate 56/63 breast cancer patients (88.9%) and 44/68 others (64.7%) enrolled (P=0.002). Of 48 who reported that they had child care responsibilities, 33 enrolled (68.8) compared to 67/83 (80.7%) of those without such responsibilities (P=0.07). Of the total sample, 88/220 (40.0%) of those without childcare responsibilities but only 32/109 (29.4) said they would be willing to participate in a placebo-controlled trial. Respondents were twice as likely to say they would participate in a trial comparing two active agents as a placebo-controlled trial. Conclusion: Our findings suggest that being asked to participate in a clinical trial may be associated with demographic factors, and that specific circumstances, such as child care responsibilities, may also affect trial participation. Awareness of these barriers may help investigators to develop effective strategies for overcoming them and for improving trial participation overall.

Abstract Background Bronchial asthma (BA) is one of the most common inflammatory airway disorders. As one of the main non-drug therapies, the Sanfu herbal patch (SHP) has been widely used to treat BA, although the evidence and mechanism are inconclusive. The objective of this pilot trial is to clarify the clinical efficacy and safety of the SHP in the treatment of BA in the chronic persistent or clinical remission stage and to provide high-quality data for further research.Methods: We propose a multicenter, double-blinded, parallel, randomized, placebo-controlled clinical trial involving 4 study hospitals in China. A total of 72 eligible participants will be randomized into an SHP group and a placebo group. They will receive SHP for 3 treatment sessions(TSs). The primary outcome will be changes in forced expiratory volume in one second after 3 TSs. Secondary outcomes will include: (1) the Asthma Quality of Life Questionnaire, Asthma Control Test, and Asthma Long-term Follow-up Scale; (2) levels of Metallothionein-2 and Transgelin-2 in blood and urine; and (3) levels of IL-5, IL-13, IL-23, IL-25, and thymic stromal lymphopoietin in blood. Analysis of the data will be performed at baseline, at the end of the 2nd and 3rd TSs and at 24-week follow-up. The safety of the SHP will be evaluated at each TS.Discussion: The aim of this trial is to determine whether SHP is more effective than placebo in the treatment of patients with BA, and whether SHP works by reducing airway inflammation and reversing bronchoconstriction.Trial registration: Chinese Clinical Trial Registry(http://www.chictr.org.cn), ChiCTR1900024616.
