- Adult, Older adult
Who may be able to join
- Patients must have a pathologically confirmed adenocarcinoma of the biliary tract (intra-hepatic, extra-hepatic (hilar, distal) or gall bladder) that is not eligible for curative resection, transplantation, or ablative therapies. Tumors of mixed histology are excluded.

- Prior surgical resection, radiation, chemoembolization, radioembolization or other local ablative therapies are permitted if completed > 4 weeks prior to enrollment AND if patient has recovered to < 1 grade 1 toxicity.
- Patients must have measurable disease (as per RECISTv1.1) in at least one site not previously treated with radiation or liver directed therapy (including bland, chemo- or radio-embolization, or ablation) either within the liver or in a metastatic site unless the patient has had complete response to 1st line platinum-based therapy.

- Have received a live vaccine within 30 days of planned start of the study therapy
Show all 12Show fewer
- Have a psychiatric illness, other significant medical illness, or social situation which, in the investigator's opinion, would limit compliance or ability to comply with study requirements

What is being measured
The primary outcome is the main question the study is designed to answer.
Proportion of Patients Alive and Without Radiological or Clinical Progression at 4 Months
Progressive disease is defined as at least a 20% increase in the sum of the longest diameter (LD) of target lesions (with a minimum absolute increase of 5 mm), taking as reference the smallest sum LD recorded since the treatment started, or the appearance of one or more new lesions.
A clinical decision of progression by the site investigator will be based on the subject's overall clinical condition, including performance status, clinical symptoms, and laboratory data.
Measured: 4 months
Secondary outcomes (5)
The Proportion of Patients That Respond to Treatment
The proportion of patients that display a partial response (PR) or complete response (CR) to treatment.
Partial response is defined as at least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD. There can be no appearance of new lesions.
Complete response is defined as the disappearance of all target lesions, determined by two separate observations conducted not less than 4 weeks apart. There can be no appearance of new lesions.
Measured: up 2 years after starting treatment, average of 4 months
Progression Free Survival (PFS) Time as Measured From Treatment Start
Progressive disease is defined as at least a 20% increase in the sum of the longest diameter (LD) of target lesions (with a minimum absolute increase of 5 mm), taking as reference the smallest sum LD recorded since the treatment started, or the appearance of one or more new lesions.
Measured: Up to 2 years
Progression Free Survival (PFS) Time as Measured From Start of 1st Line Platinum Therapy
Progressive disease is defined as at least a 20% increase in the sum of the longest diameter (LD) of target lesions (with a minimum absolute increase of 5 mm), taking as reference the smallest sum LD recorded since the treatment started, or the appearance of one or more new lesions.
Measured: Up to two years post treatment discontinuation
Overall Survival (OS) Time as Measured From Treatment Start
Measured: Up to two years post treatment discontinuation
Overall Survival (OS) Time as Measured From Start of 1st Line Platinum Therapy
Measured: Up to two years post treatment discontinuation

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Rucaparib and Nivolumab in people with Biliary Tract Cancer, run by University of Michigan Rogel Cancer Center at 3 sites in United States.
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 12 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: finished, as of the sponsor's last update on 3 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in United States. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 21 Aug 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Proportion of Patients Alive and Without Radiological or Clinical Progression at 4 Months (time frame: 4 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03639935, which also lists 1 linked publication.
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 3 Jun 2025.
