Results showed that vismodegib shrank tumours in a predefined percentage of patients in the study.

8 Oportunidades para el desarrollo de estudios clínicos en LA

9 Algunas conclusiones La inversión en investigación clínica en Oncología alcanza aproximadamente el 20% del total de la inversión en I+D farmacéutica. Se estima el costo de desarrollo de un nuevo fármaco en 1.2 billones de dólares pero la preocupación de las empresas es como ser más eficientes, incrementando la seguridad, aportando diferencias tangibles, reduciendo costos y tiempo al mercado. Latinoamérica ha avanzado en la mejora de marcos regulatorios y recursos humanos, con ventajas competitivas frente a países emergentes (China) y Europa Oriental. Surgen nuevas áreas de diseño de estudios clínicos dentro del ciclo de vida de un medicamento que son especialmente atractivas para LA. Fuentes: PhRMA; DATAMONITOR, Spectrum, PharmaVenture

14 Increasing duration of clinical trials
Evaluation of clinical trial duration by indication and phase of development, 2001–06 In 2002–04, the average time taken for a drug entering Phase I clinical trials to completing Phase III was 7.0 years, a rise of 1.2 years over calculations made in 1999–2001, in part driven by the heightening safety concerns of the FDA. The Agency’s advisory panel has recently recommended that the FDA demand additional cardiovascular testing for all new diabetes drugs, and that companies conduct long-term studies to rule out unacceptable cardiovascular risks for new diabetes compounds. Similar recommendations could conceivably be made across other therapy areas in the future, further prolonging clinical trial durations.

15 Growing size of clinical trials
Numbers of enrollees by therapy area for Phase III clinical trials conducted in the US in 2007–08 The size of clinical trials is increasing due to the requirement for growing quantities of clinical data in response to more stringent regulatory scrutiny, and concerns over drug safety. In order to increase the power and potential statistical significance of a study, a larger number of enrollees are required. However, increasing patient recruitment is directly linked to study duration and cost. Drugs to treat cancer, cardiovascular disease, diabetes and endocrinology recruited a considerably larger number of enrollees than for the remaining therapy areas. This is likely to be attributed to the large patient populations within these therapy areas and therefore ease of recruitment of such patients.

16 The cost of R&D is increasing
The growing complexity of clinical trial protocols has resulted in patient recruitment rates dropping from 75% in 1999–2002 to 59% in 2002–06, while volunteer retention rates fell from 69% to 48% over the same period. Increasing the size, complexity and duration of clinical trials generates a greater volume of data, which increases the time and costs of data capture and analysis, as well as management of the clinical trial process. Clinical trials with a high degree of complexity are more costly, 2006 Source: Datamonitor adapted from Fast Track Systems (2006) 16 16

17 Clinical trial success rates are declining
Evaluation of clinical trial to launch success rates by indication and phase, 2001–06 Pharma will have to become more astute when selecting which compounds to progress to Phase III development. This is further hampered by falling success rates for clinical trials. The success rates for drugs entering a clinical development stage (Phase I, II, and III) and progressing to actual launch has fallen by 23%, 20% and 11%, respectively (2001–06), an observation common to all individual indications analyzed and at every stage of clinical development.

18 Why Phase III drugs fail?
Why Phase III drugs fail – therapy area analysis Approximately 58% of Phase III clinical trials are unsuccessful, with the primary cause for failure being the inability of the trial data to demonstrate efficacy of the tested product against placebo. Success, or rather failure of a Phase III trial is also dependent on the following two factors: whether a drug has an established or novel mechanism of action; whether trial endpoints are objective or subjective.
