A washout period of eight weeks is required for enzalutamide and apalutamide before the patient receives their first dose of TT-702. A washout period of 4 weeks or 5 half-lives whichever is shorter for any other previous preceding IMPs is required before the patient receives their first dose of TT-702 (in the combination cohorts no washout is needed from PD-1/PD-L1 and darolutamide, respectively).

Patients with ongoing toxic manifestations of previous treatments greater than NCI CTCAE Version 5.0 Grade 1. Exceptions to this are alopecia and any ongoing toxic manifestation which in the opinion of the Investigator should not exclude the patient.

Asymptomatic patients with previously treated and stable brain metastases (in previous four weeks to study entry) and not requiring any steroids are eligible for the trial. Patients who are stable on anticonvulsants are also eligible.
