Chi stabilisce in medicina cosa è efficace e cosa no? Una volta c’era qualche conoscenza sulle cause delle malattie (non molte, fino a 60 anni fa) e soprattutto “l’esperienza” del medico Esperienza era aver visto altri casi simili e cercare di ricordarsi chi, in seguito a quale cura, stava meglio o era guarito e chi no

I nuovi ammalati si curavano con quello che si pensava avesse fatto bene agli

I nuovi ammalati si curavano con quello che si pensava avesse fatto bene agli altri Molti medici le loro esperienze le scrivevano su libri o riviste Altri ne parlavano con altri medici, si creava una tradizione ma questo metodo era molto pericoloso

PLACEBO Placebo e’ una qualsiasi sostanza innocua o un qualsiasi intervento non farmacologico privi di efficacia terapeutica. E’ deliberatamente somministrato alla persona che acconsente di assumerlo come alternativa a un trattamento attivo di cui si voglia sperimentare l’efficacia o la sicurezza.

L’uso del placebo quindi e’ legittimo solo a scopo sperimentale e solo in presenza del consenso informato del paziente e, secondo la Dichiarazione di Helsinki, solo se non vi siano trattamenti di provata efficacia per la situazione clinica soggetta a sperimentazione. Somministrare un nuovo farmaco potenzialmente efficace al di fuori di un contesto sperimentale significherebbe esporre il paziente al rischio di una sua tossicita’ sconosciuta; negarglielo a priori significherebbe privarlo della possibilita’ di goderne il possibile effetto benefico.

L’unica soluzione eticamente e scientificamente valida e’ la sperimentazione: il caso (la randomizzazione) distribuira’

L’unica soluzione eticamente e scientificamente valida e’ la sperimentazione: il caso (la randomizzazione) distribuira’ trattamento potenzialmente efficace o placebo a una popolazione di pazienti e il confronto dell’esito clinico nei due gruppi di trattamento consentira’ di concludere se il farmaco sperimentale e’ superiore al placebo.

Many current treatments - e. g. steroids in many autoimmune disases - are not based on results from RCT. Their efficacy is self evident and it would sound unethical to test them against placebo. On the other hand, we are watching the growth of trials with ‘new’ molecules whose results do not to provide any major advantage (at least not to patients) over current medical practive.

NON INFERIORITY TRIALS The new products offer little innovation. Some analyses indicate that only 10 -20% of the products reaching the market offer substantial advantages over existing ones Use of equivalence or non-inferiority trials rather than superiority designs implies the intention of not trying to prove any additional value of new drugs Non-inferiority allows new products to compete with older ones on the basis of small differences made to seem to benefit patients Garattini S, BJCP, 2004
