The dream of any physician and consequently every patient is to receive the right treatment in the right time with cost effectiveness. To achieve this goal, the 3 pillars: evidence based medicine, clinical research innovation & resources utilization should be integrated efficiently.
In this presentation, I'll try to comprehensively review the following:
1- How are we used to perform clinical trials in Oncology?
2- Does it fits in today’s needs?
3- Integration of biology knowledge in shaping drug development
4- New Clinical trial designs “Can they offer solution for accelerating drug development?”
5- The supporting infrastructure role in clinical trial execution

• It is the first to test, with a randomized control, the idea of whether off-label use of commercial drugs for matched molecular
biomarkers confers a clinical benefit.
• The results suggest that off-label use of molecularly targeted agents in this manner should be restricted.
• Instead, patients should be encouraged to participate in well-designed next-generation clinical trials that use an iterative
and scientific approach to build on findings from trials such as SHIVA
• Irrespective of these limitations, SHIVA offers robust evidence for deficiencies in assigning therapy based on the various
loose associations between biomarkers and inhibitors that are often provided in commercial clinical diagnostic reports.
24. Basket Trial
• Histology-independent trial design
• Patients with cancers of different histology enrolled in the clinical trial
based on the presence of a specific molecular aberration
27. CREATE EORTC TRIAL
• Six Cohorts of rare solid tumors and anaplastic large cell lymphoma
• ALK and/or MET alterations are considered to play a role of the carcinogenesis process of these tumors
Clinical trial information: NCT01524926

31. BASKET TRIAL: PROS AND CONS
• Pros
• Determining potential tumor efficacy of a single targeted agent in different
cancer types with the same gene abnormality
• Cons
• Risk of overlooking the impact of tumor histology type. In fact, different
tumor responses by targeting the same mutation in several cancer types
could be observed. (e.g. BRAF in melanoma versus BRAF in colorectal cancer:
RR 50%-60% versus <5%)
32. ADAPTIVE TRIALS (1)
The principle of this trial is based on modifying parameters (dose,
sample size, drug, schedule …) of a clinical trial evaluating a treatment
in accord with observed outcomes in participants.

I-SPY 2 trial
Multicenter, adaptive phase 2 trial of neoadjuvant therapy
for:
• High risk clinical stage II or III breast cancer evaluated
multiple new agents added to standard chemotherapy
To assess the effects on rates of pathological
complete response
36. Park et al. New Eng J Med 2016
Neratinib (HKI-272; Puma Biotechnology)
• an irreversible small-molecule inhibitor of the ErbB and the human
epidermal Growth factor receptor (HER) kinase family (epidermal
growth Factor receptor, HER2, and HER4)
• It has shown promising activity against HER2-positive metastatic
breast cancer.
• There is also evidence of preclinical activity against HER2negative
tumor cells
37. Probability Distributions for Selected
Biomarker Signatures
Park et al. New Eng J Med 2016
Eligible women were categorized according to
• 8 biomarker Subtypes on the basis of
• Human epidermal growth factor receptor 2 (HER2)
status
• Hormone-receptor status
• Risk according to a 70-geneprofile
38. Final Posterior and Predictive Probabilities of Neratinib
Efficacy with Regard to 10 Biomarker Signatures
* The status of high-risk category 2 on the 70-gene profile was determined with the use of the MammaPrint assay

39. Final Posterior and Predictive Probabilities of Neratinib
Efficacy with Regard to 10 Biomarker Signatures
* The status of high-risk category 2 on the 70-gene profile was determined with the use of the MammaPrint assay
Park et al. New Eng J Med 2016
• Neratinib reached the pre-specified efficacy threshold with regard to the
HER2-positive, hormone-receptor–negative signature
• Neratinib added to standard therapy was highly likely to result in higher
rates of pathological complete response than standard chemotherapy
with trastuzumab among patients with HER2-positive, hormone-
receptor–negative breast cancer.
40. ADAPTIVE TRIAL DESIGN: PROS AND CONS
• Pros
• Faster evaluation of the drug
• Modification of drug, dosage and sample size during the trial according to the
observed results
• Cons
• Practical difficulties during the performance of the trial
• The clinicians are not familiar with the essential statistical part of this
approach
• Active and dynamic follow-up of the trial is needed
41. WHAT ARE THE CHALLENGES OF THE NEW CLINICAL TRIAL
DESIGNS?
• To show significant benefit in overall survival
• Rapidly evolving and not validated technics in use for tumor
sequencing (NGS, circulating tumors cells, circulating tumor DNA…)
• High number of screened patients is needed
A strong infrastructure behind is needed to execute such trials with quality assurance

47. Conclusion
• We need to adapt in our trials according to the accelerating needs
• Networking between institutions to render molecular tumor board
accessible to the majority of centers and consequently to clinical trials and
new drugs
• More collaboration with pharmaceutical companies due to the need of
drugs (including off label drugs) with the different mechanisms of action to
be used in precision medicine at the right time for the patient
• Validation Role of biomarkers and/or molecular imaging in determining
mainly the negative predictive value of an evaluated drug
• We need the infrastructure that can support such complex trials
