SummaryThe goal of this prospective investigation was to study the course and the quality of patient-psychiatrist relationships during phase II / phase III clinical trials of antidepressant medication prescribed for depressive disorders. All patients who participated in the clinical trials (and subsequently in this survey) signed written informed consent statements and were subject to random double blind treatment assignment. Retrospective analysis of 118 investigations was carried out, and the patients involved were questioned concerning their experiences and impressions during and after the study. Data show that the outcome of clinical trials of antidepressant drugs are not a function of pre-existing good patient-psychiatrist relationships. On the other hand, no effects on the patient-psychiatrist relationship were found as a result of the experimental procedure, and it can be concluded that no detrimental effects on future patient-psychiatrist relationships were incurred.

Testosterone Transdermal Patch (TTP) has been developed for the treatment of postmeno-pausal women (PMW) with hypoactive sexual desire disorder (HSDD). Since the cardiovascular (CV) effects of testosterone in women are still unclear we conducted a pooled analysis of the large phase III clinical program to evaluate the efficacy and safety of 300 μg/day TTP, alone or in association with hormone replacement therapy (HRT), versus placebo in surgical or natural PMW. Design & Methods: A total of 2795 women aged between 26 –70 years (mean age 52(SD=6.8) years) were included in 5 phase III randomized, double-blind, placebo-controlled clinical trials (treatment duration range 24 – 52 weeks) as part of the TTP Clinical program. 4 studies included PMW (natural and surgical, two each respectively) receiving HRT while 1 study was conducted without HRT, in either surgical or natural PMW. Women with known CV disorders were excluded from the studies. Changes from baseline in standard metabolic and CV risk factors were compared. The incidence of stroke, myocardial infarction (MI) and venous thromboembolism (VTE) alone or as a composite CV endpoint was assessed. Results: The 2795 PMW were randomized to receive either placebo (n=1297) or TTP (n=1498). Baseline mean BMI was 27 kg/m2 (SD=5.3 kg/m2) and 56% were naturally menopausal. The demographic and baseline parameters were similar among the treatment groups. No significant changes in CV risk factors (Total Cholesterol, Triglycerides, Insulin, Glucose, Systolic and Diastolic Blood Pressure) were detected during the study period, apart from a blunting of the increases in HDL-C by TTP at 24 and 52 weeks (Placebo 52-week mean change 2.59 mg/dl vs. TTP 52-week mean change 1.20 mg/dl, p<0.005) and of the decrease in LDL-C by TTP at 24 (p<0.05), but not at 52 weeks. During the double-blind (24 weeks), placebo-controlled period of the combined studies, 4 major CV events (2 MIs and 2 strokes) were reported in placebo patients and 3 (2 MIs and 1 stroke) in those receiving TTP. One VTE occurred in a patient receiving TTP and HRT. Conclusion: TTP therapy in these clinical trials did not adversely affect CV risk profile and did not change the risk of major CV events in these surgical and naturally PMW with or without concomitant HRT.

This paper will address some of the current issues concerning the conduct of phase III clinical trials. The issues to be discussed fall into two areas – trial design and mensuration of target variable change. The former includes the determination of sample size; selection bias in sample populations due to particular inclusion and exclusion criteria; ensuring trials are randomised, double blind controlled studies; and designing the trial so that the two arms are balanced in every way possible, with especial reference to matching treatment variables. The mensuration of target variable change includes the selection of appropriate rating instruments which are (i) sensitive to target symptoms, (ii) have been adequately profiled psychometrically in a similar population, and (iii) are able to detect change within the time frame of the study. Instruments should be cross-culturally robust if used in multi-country studies and should have validated local versions where possible. Adequate training in the use of the rating instruments should be clearly reported and a clear description of inter-rater reliability assessment and maintenance should be provided. Brief mention will be made of the Cochrane collaboration and the role of evidence-based medicine in clinical trials.
