In early 20th c., drugs promoted with no regard to truthfulness of claims being made - Claims relate to effectiveness, side effects/adverse reactions, contraindications Late 1930s, first "antibiotics" became available - sulphanilamides usually sold as tablet - Demand for liquid form for kids - difficulty finding solvent - Diethylene glycol used as solvent - No trials conducted, no animal studies - 240 gallons made - 107 kids died
Thalidomide Discovered 1950s by German company Chemie Gruenthal No proper clinical trials Chemie Gruenthal marketed thalidomide under various names incl. "Contergan" - first marketed 1956 for respiratory infections; then in 1958 as sedative Side effects: sleepiness, drowsiness, constipation, skin rash, severe headaches, peripheral neuropathy, dizziness, nausea, depression/mood swings, shivering/buzzing in ears; absolute prohibition against use during pregnancy Now being prescribed for range of new indications - may well be effective in treatment of tuberculosis, leprosy, incurable bone marrow cancer (multiple myeloma), complications of AIDS (mouth ulcers); also being tested for other cancers incl. lung cancer
Contergan Marketed with Aspirin over counter Doctors asked to test drug Side effects: by 1959, reports of side effects received by company - e.g. Dr Ralph Voss observed case of polyneuritis on 3.1.59 - wrote to company asking if this could be due to drug - Dr Werner and Dr Sieners replied this had never been observed -- Claim was untrue - 5-20% incidence of side effects Side effects: mid-1960s, drug been sold for about 4 years Company without clinical head of its testing section - numerous reports of side effects By end of 1960, 1600 reports of side effects, with 100 cases of severe polyneuritis existed Late 1960, Dr Horst Frenkel (neurologist) wrote to company stating he was going to publish 20 observations of nerve damage - Reps of company visited Frenkel and journal editors to attempt to prevent publication - publication delayed By 4.5.61, reports both Britain and Germany of polyneuritis - critical reviews in German magazines Company continued unrestrained marketing - To maintain maximum turnover, Dr Oswald and Dr Nowel visited superintendent of health departments of ministries of interior affairs and gave special prominence to "contergan as good as ataxic" and "side effects practically never occurred"
Key areas
Key areas Control of drug name (trade/genetic) Disclosure of side effects Limits of effectiveness
1960s Control of drug name: chemical name; generic name; trade/brand name; products more expensive if sold by trade name Disclosure of side effects: previous ads didn't require side effects to be states; now complete statement of side effects and contraindications are required Limits of drug's effectiveness: ; Fair Balance now bans drugs which ignore recent findings; ignore published articles detailing side effects; implies that study reflects greater experience with drug than it does in fact; fails to reveal that favourable studies conflict with other reliable studies; suggest (improperly) that animal studies have clinical significance

In clinical trials the effect of the active drug is drug response minus placebo response For most clinical trials there are statistically significant differences between treatment and placebo groups
Most new drugs which are developed are rarely truly new treatments New drugs marketed as improved treatment Yet clinical trials almost always compare no treatment vs. new treatment Very rarely is comparison current treatment vs. new treatment
Advantage of placebo is that it produces no adverse side effects
