Extra training: Symposia, conferences,…

Contacts with drug reps

How many clinical research is industry funded?

Anderson et al., NEJM, 2015

Impact of the sponsor of the study on efficacy results

Impact of sponsor of the trial on outcome of psychiatric drug studies

Industry supported Studies

Independently funded trials

ISS-competitor drug

Kelly et al., 2006N= 542 publications (1992, 2002)

Percentage of Favorable outcome reports according to trial sponsor

Heres et al., Am J Psychiatry, 2006

Reboxetine for acute treatment of major depression: systematic review and meta-analysis of published and unpublished trials

Forest plot showing meta-analyses of remission and response rates for trials that compared reboxetine with placebo. Empty boxes show published studies and filled boxes show unpublished studies.

What about clinicaltrials.gov?2000: creation of clinicaltrials.gov

information about and access to clinical trials

In 2007:FDA requires sponsors to register and report basic summary results at clinicaltrials.gov

FDA also mandates that trial results be reported by the sponsor within 1 year after the completion of data collection

Are psychiatrists influenced by the pharmaceutical industry?

Conclusions

Opinion leaders in the media

Impact of pharma representatives visits

Pharmaceutical industry spent 57.5 billion dollars on pharmaceutical promotion in US in 2004

Impact of contacts with Pharma sales representatives or sponsored meeting (1,2)

Increased prescription rates of sponsored drug

Lower adherence to guidelines and recommendations

higher prescribing cost

(1) Spurling et al, 2010 (2) Spingarn et al., 1996

Reps actively selected for outgoing nature, befriending style

Assessing the physician’s personalities

‘Physician category’

Technique per category how to convince to prescribe

Personal information is asked for (and put in database)

Skeptical doctors are wooed as teachers

Prescription tracking (IMS health buys records from pharmacies)

Identifying physicians susceptible for marketing

Seeding trialsTrials sponsored by sales and marketing department rather than R&D division

‘Investigators’ chosen not for their expertise, but because they prescribe competitor’s drug

Especially opinion leaders

Multiple inclusion sites (sometimes >100)

Study design is poor

But things are (somewhat) changing..Golden era is over, products are getting off patent

Increasing awareness

Conferences & symposia no longer sponsored (APA,…)

Fewer/no more gifts

Pharmaceutical industry also making effort to more balanced interaction:

betransparent.be

Decline in reps, focus on ‘key figures’:

Teachers, speakers, admission unit psychiatrists

Rise of digital tools

Infogaming

e-learning

Conclusions

StellingenTweede generatie zijn beter dan eerste generatie antipsychotica tegen positieve symptomen

Tweede generatie zijn beter dan eerste generatie antipsychotica tegen negatieve symptomen

Tweede generatie zijn beter dan eerste generatie antipsychotica tegen cognitieve symptomen

Tweede generatie antipsychotica hebben een gunstiger nevenwerkingsprofiel?
