Here, we review the scientific and clinical rationale supporting the rapid translation of this promising metabolic modulator in early-phase cancer clinical trials. Despite enormous investments from industry and the public, oncology has an impressively poor success rate in the clinical development of effective investigational drugs; less than a third of that in cardiovascular or infectious diseases Kamb et al, Drug development in oncology has typically focused on targets essential for the survival of all dividing cells, leading to narrow therapeutic windows.
Non-essential targets offer more selectivity but little efficacy. It is extremely rare to find an essential target that is unique to cancer cells; the dependence of CML cells on Ableson kinase is only induced by a chromosomal translocation in the malignant clone, making the efficacy and selectivity of imatinib for CML an exception in cancer therapy Kamb et al, The most important reason for the poor performance of cancer drugs is the remarkable heterogeneity and adaptability of cancer cells.
The molecular characteristics of histologically identical cancers are often dissimilar and molecular heterogeneity frequently exists within a single tumour. This has important implications, including the realisation that specific drugs have to be developed and tested for molecularly defined tumours and effects in one might not necessarily be relevant to another cancer.
The biggest challenge remains the selective induction of cell death mainly apoptosis in cancer but not normal cells.
Pragmatically, an ideal anticancer therapy would be easily administered possibly an orally available small molecule and affordable.

I never expected to win an award and I have to say it is one of the best moments of my life! We really enjoyed the event. If a treatable blockage is noted, the first catheter is exchanged for a guiding catheter. Once the guiding catheter is in place, a guide wire is advanced across the blockage, then a catheter designed for lesion cutting is advanced across the blockage site.
Directional coronary atherectomy (DCA)
A low-pressure balloon, which is attached to the catheter adjacent to the cutter, is inflated such that the lesion material is exposed to the cutter.
The cutter spins, cutting away pieces of the blockage.
These lesion pieces are stored in a section of the catheter called a nosecone, and removed after the intervention is complete. Together with rotation of the catheter, the balloon can be deflated and re-inflated to cut the blockage in any direction, allowing for uniform debulking. A device called a stent may be placed within the coronary artery to keep the vessel open.
After the intervention is completed the doctor injects contrast media and takes an x-ray to check for any change in the arteries.
