Description of intervention(s) / exposure
This is an open label phase II trial in the neo-adjuvant setting. After signing informed consent, patients will be treated with combination Degarelix 240/80 mg subcutaneously plus Erdafitinib 8 mg orally.. A starting dose of 240 mg of Degarelix is administered as two consecutive subcutaneous injections of 120 mg each, a maintenance dose of 80 mg is administered as one subcutaneous injection for each following month. An initial dose of 8 mg of Erdafitinib is taken orally daily with subsequent up-titration based on serum phosphate levels. Combined Erdafitinib plus Degarelix is given for 3 months, followed by Degarelix alone, for a further 1 month prior to radical prostatectomy. Compliance will be monitored by counting the Erdafitinib capsules at each visit, this will be logged on the drug accountability sheet and signed by the Principal Investigator. Participants will have regular blood tests to keep an eye on any possible side effects from these medications.

Outcomes
Primary outcome [1] 305243 0
Safety and tolerability of combination Degarelix and Erdafitinib in the neo-adjuvant setting.

Participants will undergo blood tests (serum assay), eye examinations (via an ophthalmological examination including; visual acuity, tonometry, fundoscopy, Amsler Grid Test, and Optical Coherence), heart examinations (12-lead ECG) and vital signs (pulse and blood pressure using a Sphygmomanometer, as well as height (stadiometer) and weight (digital scales) checked at regular intervals throughout the study to monitor the possible side effects from these treatments.

These are composite primary outcomes.
Timepoint [1] 305243 0
*Bloods tests (Pre-study visit, Week 1, 3, 5, 7, 9, 13 and 17 pre-surgery, then 4-weeks, 24-weeks and 52-weeks post surgery).

*Eye examinations (visual acuity, tonometry, fundoscopy, and Optical Coherence checked at pre-study visit and again If clinically indicated based on presence of new visual symptoms or abnormal Amsler grid test).

*Eye examinations (Amsler grid test checked at pre-study visit, week 1, 5, 9, 13, 15 and 17 pre-surgery, then 4-weeks, 24-weeks and 52-weeks post-surgery).

*Heart examinations (checked at pre-study visit and week 1, 5, 9 and 13 pre-surgery).

*Vital signs (checked at pre-study visit, week 1, 5, 9, 13 and 17 pre-surgery, and 4-weeks, 24-weeks and 52-weeks post-surgery).
