Personalised Cancer Therapeutics for your patients.
The world’s only strategy using real patients’ avatars for drug screening.
PDP identifies the precise combination of FDA/NICE-approved drugs (including non-cancer drugs) that works optimally on your patient’s specific tumour, mirroring its genetic complexity and increasing the prospects of an efficient treatment while also reducing toxicity and side effects.
01 Personal Discovery Process TM
Personal Discovery Process TM
PDP first identifies all gene mutations associated with the patient’s tumour via whole exome sequencing. DNA can be extracted from either a new biopsy or from a previous histologic sample used for diagnosis as well as a blood sample.
This complex oncogenetic network is modelled in the intestine of the fruit fly, Drosophila melanogaster, to generate a personalised fly avatar that carries the patient cancer.
Up to 500,000 avatar flies are grown for each patient and used to screen ~2000 drugs and drug combinations covering the full FDA /NICE library of approved compounds.
02 Who can benefit from the Personal Discovery Process TM
What is the evidence that PDP works?
Case studies of cancer patients receiving therapy developed by PDP have been published here and here.
How does PDP compare to targeted therapies?
However, almost every tumour will show several actionable mutated genes, e.g. BRAF + APC + EGFR + PTEN. Taking one drug for every target is not possible because of the high toxicity produced by the combination of anti-cancer drugs. Thus, the oncologist is forced to choose from one of these mutations and select a targeted therapy based on partial genetic information, leading to failed treatments and tumour resistance.
PDP can introduce up to 20 cancer associated mutations per avatar and find the drug cocktails that target the oncogenic network created by them. Thus, the treatment recommendation is developed based on a comprehensive mutational cancer landscape.
Who can benefit from PDP?
PDP can help identify optimal treatments for patients with early cancers as well as for patients with difficult to treat advanced cancers, who have exhausted treatment options with conventional approaches.
Finally, people with pre-malignant gut lesions can also benefit from PDP. The presence of adenomas in the digestive tract is well correlated with the development of a colorectal cancer in the following years. Non cancer patients with this feature can greatly benefit from having a pre-avatar model already built and ready to provide a treatment recommendation when required.

What is the rationale for using flies to find the most appropriate personalised therapy?
The small size and the short life cycle of these animals permits the fast expansion of the avatar population. In this way, we create and utilise 500K flies (an impossible number for any other animal model) to run a high-throughput drug screening, allowing us to generate powerful pre-clinical statistics for every drug or drug combination tested.
Roughly 75% of human disease-causing genes have a functional counterpart in the fly. Drosophila has been used since the early 1900s to study human diseases, including cancer. The signalling pathways involved in cancer are conserved in fruit flies and in fact many components of these signalling pathways were first discovered in the fly.
How long does PDP take?
The difference in time reflects differences in tumour type, complexity, the number of drugs and drug combinations tested until the final cocktail is identified.
Why is PDP better than other personalised options?
Although initially promising, the implementation of PDX mice for the identification of personalised treatments has been halted due to lack of success and cost constraints, and they are currently used for academic research only. Cell-based strategies such as organoids built from a patient’s cancer cells are available. However, organoids can be obtained for only a fraction of patients and they are used to test standard of care medicines.
Moreover, as these cancer cells are artificially cultured, they lack realistic drug responses because they are acting in an in vitro artificial environment. Therefore, Vivan’s technology is positioned at the forefront of personalised medicine.
