About this study

Official title: A Phase I, Open-label Study to Assess the Absolute Bioavailability of Saruparib (AZD5305) and Absorption, Distribution, Metabolism, and Excretion (ADME) of [14C]-Saruparib ([14C]-AZD5305) in Patients With Advanced Solid Malignancies

This Phase I, open-label study aims to study to absolute bioavailability of Saruparib (AZD5305) and the absorption, distribution, metabolism and excretion (ADME) of [14C]-Saruparib in patients with advanced solid malignancies.

This will be done on an inpatient basis in 2 parts (single-dose oral administration with radiolabeled microtracer in Part A, single-dose IV radiolabeled administration in Part B) during which samples will be obtained of plasma, urine, feces and vomitus (where applicable).

Read the detailed description

This is an open-label, 2-part study in participants with advanced solid malignancies and will be conducted at multiple study sites.

Participants will be assessed for study eligibility prior to admission to the study site during a 28-day screening period. Participants will take part in both Parts A and B of the study.

Part A will assess the absolute bioavailability and evaluate the PK parameters of oral Saruparib and a radiolabelled IV microdose of [14C]-Saruparib

Participants will be admitted to the study site pre-dose of Part A and will remain resident at the study site for PK sampling and safety assessments.

A washout period will be observed between doses of Saruparib in Parts A and B.

Part B will assess the ADME of oral [14C]-Saruparib. Participants will be readmitted to the study site for Part B and will remain resident at the study site for excreta (urine, faeces, and any vomitus) collections, PK sampling, and safety assessments. Participants may be discharged from the study site prior to the last indicated day if both the following discharge criteria are met:

  1. ≥ 90% mass balance recovery, and
  2. < 1% of the total radioactive dose is recovered in combined excreta (urine and faeces) in 2 consecutive 24-hour periods.

Participants will return to the study site for a Follow-up Visit after the last dose of Saruparib which will include routine safety assessments. After the completion of Parts A and B, and following the Follow-up Visit, participants may be allowed further access to Saruparib.

Additional safety data collection will be conducted.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Saruparib (AZD5305), [14C]-AZD5305 microtracer and [14C]-AZD5305 (therapeutic dose) in people with Locally Advanced or Metastatic Solid Tumor, run by AstraZeneca at 2 sites in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 11 inclusion and 29 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 24 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact AstraZeneca Clinical Study Information Center (1-877-240-9479, information.center@astrazeneca.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Absolute bioavailability (F) of Saruparib (time frame: Day 4). The study lists 17 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Jun 2026.
