Scientific titleMAGnetic NAnoparticle thermoaBLATion -– retention and maintenance in prostatE: a Phase 0 study in men (MAGNABLATE I trial)
Study acronymMAGNABLATE I
Study objectivesThis Phase 0 dose escalation safety trial aims to evaluate the retention of magnetic nanoparticles in the prostate.

The primary study objectives are:-
1. To conduct a dose escalation safety trial of magnetic nanoparticles injected into the prostates of men prior to cystoprostatectomy.
2. To conduct a dose escalation safety trial of magnetic nanoparticles injected into the prostates of men prior to prostatectomy.
3. To evaluate ex-vivo prostates with a special marker to determine the retention and distribution of the magnetic nanoparticles in relation to the intended target area at time of injection.

The secondary study objectives are:-
To evaluate the anatomical distribution of magnetic nanoparticles compared with injection site in prostate assessed by both Perls’ staining and postoperative imaging (MRI and CT) of the ex vivo tissue.
Ethics approval(s)First MREC approval date 17/09/2013, ref: 13/LO/1233
Health condition(s) or problem(s) studiedTopic: National Cancer Research Network; Subtopic: Prostate Cancer; Disease: Prostate
InterventionThe trialists are aiming for a minimum of 60% of injected nanoparticles to be retained within the prostate over an average of first 6 patients. They aim to recruit a representative group of men who have overt cancer lesions as well as overt benign areas for injection.
They are aiming for the following:
Minimum number of benign prostate lobes 12
Minimum number of malignant lobes 6
Men undergoing Radical Cystoprostatectomy and Radical Prostatectomy will be recruited until the above numbers are fullfilled.

Injection of nano-particles, Pre-operative preparation: This procedure will be carried out just prior to the surgery (cystoprostatectomy or prostatectomy). The patient will be admitted on the morning of the procedure. The patient will be asked to sign the hospital procedure specific consent form.
Procedure set-up: Intravenous antibiotics (Gentamicin 120mg and Cefuroxime 1.5gm) are given just prior to injection unless contra-indicated.
The injection will be administered under general anaesthetic.

Surgery, Removal of prostate during radical cystoprostatectomy or radical prostatectomy surgery
Post-procedure care: The patient is discharged home once he has recovered from his major surgery as per standard of care. A contact number is given to the patient to call if any problems are encountered.
Intervention typeOther
Primary outcome measureRate of serious and other adverse events; Timepoint(s): For the duration the patient is in the study
Secondary outcome measures1. Anatomical distribution of magnetic nanoparticles compared with injection site in prostate; Timepoint(s): On removal of the prostate
2. Percentage microsphere retention using Perl staining on whole-mount histology; Timepoint(s): At removal of the prostate
