Arms & Interventions

Module 1 Part A Multiple ascending dose cohort and Paired Biopsy Breast Cancer Expansion Cohortexperimental

Module 1 Part A Multiple ascending dose cohort: Participants with advanced solid tumours receive CT7001 (samuraciclib) as oral monotherapy, in ascending dose cohorts, to identify the maximum tolerated dose (MTD), minimally biologically active dose (MBAD) and recommended dose for Phase II testing (RP2D). Following completion of the dose escalation part of Module 1A, participants to receive safe, tolerable and MBAD of CT7001 for the paired biopsy expansion cohort. Module 1 Part A Paired Biopsy Breast Cancer Expansion Cohort: Participants with locally advanced or metastatic breast cancer will receive CT7001 (samuraciclib) as oral monotherapy at the minimally biologically active dose (MBAD) and recommended dose for Phase II testing (RP2D).

Drug: CT7001
Module 1 Part B-1 Triple-negative breast cancer (TNBC) Expansionexperimental

Participants with locally advanced or metastatic triple-negative breast cancer (TNBC) will receive CT7001(samuraciclib) as oral monotherapy at the dose, frequency and schedule recommended from Module 1 Part A.

Drug: CT7001
Module 1 Part B-2 Castrate resistant prostate Cancer (CRPC) Expansionexperimental

Participants with castrate resistant prostate cancer will receive CT7001(samuraciclib) as oral monotherapy at the dose, frequency and schedule recommended from Module 1 Part A.

Drug: CT7001
Module 2 Part Aexperimental

Participants with locally advanced or metastatic HR+ve and HER2-ve breast cancer will receive CT7001 (samuraciclib) at the dose, frequency and schedule recommended from Module 1 part A and will receive Fulvestrant solution in pre-filled syringe for intramuscular (IM) injection

Drug: CT7001Drug: Fulvestrant
Module 4experimental

Participants with advanced solid tumours will receive CT7001(samuraciclib) oral monotherapy in a randomized, balanced, single-dose, two-treatment (fed v fasting), two-period, two-sequence crossover study followed by once daily continuous dosing.

Drug: CT7001
