Funded PhD Opportunity Targeted Chemo-Sonodynamic Therapy in combination with Androgen Deprivation Therapy to treat advanced prostate cancer using ultrasound responsive microbubbles as a delivery vehicle.

This opportunity is now closed.

Subject: Biomedical Sciences

Summary

Clinical studies have indicated that combining docetaxel chemotherapy with standard hormonal therapy significantly improves the survival outcome for patients with newly diagnosed advanced prostate cancer.1 One reason for this observation is that attacking testosterone independent cellular clones early with chemotherapy enables hormonal therapy to keep prostate cancer in remission longer.2

However, the lack of tumour targeting associated with chemotherapy drugs such as docetaxel, means non-target tissue is also exposed resulting in significant side-effects for the patient. Ultrasound targeted microbubble destruction (UTMD) is an emerging strategy for the site-specific delivery of drug payloads to solid tumours.3 In UTMD, low intensity ultrasound is used to disrupt (burst) the microbubbles in the tumour microenvironment, thus releasing attached / encapsulated payloads in a site-specific manner.The physical effects that accompany microbubble destruction are also known to facilitate the delivery of the drugs deep into the tumour tissue thus enhancing their action.4-5

In this project, we will use our microbubble platform to enable then targeted delivery of docetaxel chemotherapy and sonodynamic therapy (SDT) to prostate tumours. Our preliminary experiments have demonstrated that UTMD mediated taxane / SDT treatment significantly reduces tumour growth when compared to androgen deprivation therapy (ADT), in mice bearing LNCaP xenograft tumours. However, these experiments used paclitaxel instead of docetaxel as the taxane based chemotherapy and did not explore the benefit of combining chemo-sonodynamic therapy with ADT.

Therefore, in this proposal, we will prepare lipid stabilised microbubbles carrying both docetaxel and Rose Bengal (a SDT sensitiser) to explore the effect of UTMD mediated combined chemo-sonodynamic therapy treatment on tumour growth and metastasis, alone and in combination with hormonal therapy.

Requisite experience

Applicants will be expected to be familiar with good laboratory practice and cell culture experience will be a benefit.   In vivo experience would be a benefit although specific training in accordance with national requirements will be provided.
