In this article, we propose a Bayesian approach to phase I/II dose-finding oncology trials by jointly modeling a binary toxicity outcome and a continuous biomarker expression outcome. We apply our method to a clinical trial of a new gene therapy for bladder cancer patients. In this trial, the biomarker expression indic…

A comparative controlled clinical trial of epsilon aminocaproic acid (EACA), 36 g/day and tranexamic acid (TEA), 6 g/day, was undertaken to assess their effectiveness in reducing early recurrence of subarachnoid haemorrhage (SAH). Of 90 patients treated with EACA recurrent haemorrhage was seen in 8% of these patients a…

The effectiveness of pirenzepine in the treatment of gastric ulcer was assessed in a double-blind 6 weeks' clinical trial in comparison with placebo. After 2 weeks of treatment 1 patient in each group showed a complete healing of gastric ulcer. After 6 weeks of treatment 9 out of 10 patients in the pirenzepine group (9…

An exercise for medical students was designed to illustrate one method of setting up a clinical trial and incidentally to demonstrate some effects of placebos. Twelve groups of four students participated: one in each group was the "recorder", the other three (volunteers) were randomly assigned to the treatment A, treat…

Deferred consent, a new approach to the requirement for informed consent in clinical research, was used in a randomized clinical trial of brain resuscitation after cardiac arrest. Because patients were comatose and therapy had to be initiated immediately, traditional prospective consent usually could not be obtained. U…

This paper updates the results of the clinical trial to examine the efficacy of exogenous leukocyte interferon therapy as adjuvant treatment for osteosarcoma. So far the incidence of metastases is lower and the survival rate is better for the interferon-treated group than for the concurrent control group. The number of…

Twenty-five volunteers, all in their fifth decade or beyond, all with mild to moderate, nonpsychotic depression of at least several months' duration participated in a double-blind study of Gerovital vs placebo. There was no significant difference between the Gerovital and placebo groups; both groups showed significant…

The therapeutic effect of lithium in Huntington's chorea was tested in six patients through a double-blind cross-over comparison of lithium and placebo, each administered for 6 weeks. Four of the patients received neuroleptic drugs at the same time. Lithium and placebo periods did not differ as regards motor skills, hy…

Lofepramine, an imipramine derivative, shows lower acute toxicity in animals when compared with desipramine and imipramine. Its anticholinergic effect is less pronounced than that of desipramine. In an open clinical trial lofepramine showed a marked antidepressive action. A double-blind multicenter trial of lofepramine…

Bay i 7433 (Copovithane) is a biological response modifier with antitumour activity in vivo, but no cytotoxic or cytostatic effect in vitro. A clinical trial of the compound at doses of 15g/m2/week was carried out for six weeks in 10 patients with various forms of cancer. Tolerance was good: no systemic toxicity was ob…

38 patients with herpes simplex keratitis were treated in double blind clinical trial. 18 patients (10 with pure epithelial and 8 with accompanying stromal affection) were treated with 3% acyclovir (ACV) eye ointment, and 20 patients (10 with pure epithelial and 10 with accompanying stromal affection) were treated with…

A prospective clinical trial compared polyglycolic acid (P.G.A.) suture material with silk in the closure of wounds in 1000 patients attending the accident service of a district hospital. Statistical analysis showed the incidence of inflammatory reaction and suppuration to be significantly lower in wounds sutured with…

Twenty-four patients with classical angina of effort completed this double-blind cross-over clinical trial of acebutolol and propranolol. Both acebutolol (100-400 mg) and propranolol (40-160 mg) three times a day produced a significant reduction in the incidence of anginal attacks, consumption of nitroglycerine tablets…
