- Brief Summary
A Phase I modular study to assess the effect of oral saruparib on other treatments in patients with advanced solid malignancies.
- Detailed Description
Module 1 of the study is a Phase I, open-label study to assess the effects of saruparib on the PK of substrates digoxin (P-gp), furosemide (OAT1/3), metformin hydrochloride (OCT2/MATE1/2K), and rosuvastatin (OATP1B1/3) in participants with advanced solid malignancies.
Module 2 of the study is a Phase I, open-label, 4-treatment period, multi-centre, relative bioavailability, PPI effect, randomised, crossover study of saruparib tablets manufactured using a direct compression (DC) process in participants with advanced solid malignancies.
Module 1 of the study will include:
* A Screening period of 28 days prior to Day 1.
* Period 1: a single dose of a cocktail of substrates (digoxin, furosemide, metformin hydrochloride, and rosuvastatin) on Day 1.
* A washout period of 1 to 3 days between Period 1 and Period 2.
* Period 2: continuous dosing of saruparib from Day 1 to Day 9. On Day 5 saruparib will be administered in combination with the cocktail of substrates.
* Period 3: a dose of saruparib per day for up to 3 cycles of 28 days each.
* An End of Study visit up to 3 days after the last dose in Period 3.
Module 2 of the study will include:
* A Screening period of 28 days prior to Day 1.
* Period 1 and Period 2: a single dose of roller compaction (RC) or DC saruparib.

-
Any condition that, in the opinion of the investigator, would interfere with evaluation of the study intervention or interpretation of participant safety or study results.

-
Uncontrolled intercurrent illness within the last 12 months, including but not limited to, serious chronic GI conditions associated with diarrhoea, or psychiatric illness/social situations that would limit compliance with study requirement, substantially increase risk of incurring AEs or compromise the ability of the participant to give written informed consent.
