The Phase 2 monotherapy portion of this study is currently enrolling and will evaluate the efficacy and safety of PC14586 (INN rezatapopt) in participants with locally advanced or metastatic solid tumors harboring a TP53 Y220C mutation. The Phase 1 portion of the study will assess the safety, tolerability and preliminary efficacy of multiple dose levels of rezatapopt as monotherapy and in Phase 1b in combination with pembrolizumab.

This is a phase 2 pragmatic study that evaluates the clinical benefit of continuing systemic therapy with the addition of locally ablative therapies for oligo-progressive solid tumors as the primary objective. The primary outcome measure is the time to treatment failure (defined as time to change in systemic failure or permanent discontinuation of therapy) following locally ablative therapy.

Pheochromocytomas and paragangliomas are neural crest-derived tumors of the nervous system that are often inherited and genetically heterogeneous. Genetic screening is recommended for patients and their relatives, and can guide clinical decisions. However, a mutation is not found in all cases. The aims of this proposal are to: 1) to map gene(s) involved in pheochromocytoma, and 2) identify genotype-phenotype correlations in patients with pheochromocytoma/paraganglioma of various genetic origins.

Patients with cancers that are sensitive to radiotherapy treatment and/or patients who have experienced severe acute/ late side effects to radiotherapy will be recruited to the study. Blood and/or matched tumour-normal tissue pairs will be collected. Blood and/or tissue samples will be processed and studied for genetic and biochemical markers that have potential to be used for predicting sensitivity to radiation.
