  • Representative archival formalin-fixed paraffin-embedded (FFPE) tumor specimens in paraffin blocks (preferred) or 20 freshly cut and unstained slides, with an associated pathology report, for ancillary studies and central testing, is mandatory for all cohorts. In all cases, recovery of the most recent tumor block or biopsy is encouraged and tumor tissue has to date back from less than 3 years ago (less than 6 years for cohort 4). Cohorts 1 and 2: if tumor tissue is more than 3 years old, a fresh tumor biopsy is mandatory. Cohort 4: if tumor tissue is more than 6 years old, a fresh tumor biopsy is mandatory.
  • Specificities for Cohorts 1A-D:
  • For patients with DNA repair gene mutation already identified by local testing, mutational testing must have been done less than one year prior to inclusion in the trial (i.e. signing of informed consent). Tumor block should correspond to the one that has been used for the original testing. If more recent blocks are available, these should be provided for ancillary studies, and the presence of the mutation of interest should be confirmed on these.
  • If no archival tissue is available or if tumor tissue is more than 3 years old, feasibility of a fresh tumor biopsy at baseline (C0D1 pre-dose) should be ensured and mutation confirmed on that tissue for cohorts 1A, 1B and 1D. Only tissue from core needle, punch or excisional biopsy sample collection will be accepted. Other methods such as fine-needle aspiration, brushing, bone tissue or lavage samples are not acceptable.
  • Bone biopsies are allowed for mCRPC (cohort 1C), if sufficient tumor cellularity can be achieved.
  • Specificity for cohort 3:
  • If no archival tumor biopsy is available, a new fresh biopsy should be done prior to treatment start (C0D1 pre-dose) whenever feasible; otherwise, any archival tumor tissue will be accepted.
  • Core or excisional biopsy from soft tissue or a bone biopsy is required from a site not previously irradiated (samples from tumors progressing in a prior site of radiation are allowed; other exceptions may be considered after Sponsor consultation).
  • Measurable disease, defined as:
  • For the non-prostate cohorts: At least one lesion, not previously irradiated, measurable according to RECIST v1.1 as ≥10 mm in the longest diameter (except lymph nodes which must have short axis ≥ 15 mm) with computed tomography (CT) or magnetic resonance imaging (MRI) and suitable for repeated assessment.
  • For prostate cohorts: At least one lesion, not previously irradiated, measurable according to RECIST v1.1 and / or bone scan measurable disease (Cf inclusion criteria 4) and / or measurable disease according to Prostate Cancer Working Group Criteria 3 (PCWG3)
  • Agreement of the patient to sign the genetic analysis consent form for access to plasma samples for ctDNA analysis.
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 with no deterioration from registration date.
  • Estimated life expectancy of greater than 12 weeks.
  • Adequate hematologic and organ function, defined by the following laboratory results obtained within 3 days prior to the first study treatment (Cycle 0 Day 1):
  • Absolute neutrophil count (ANC) ≥ 1500 cells/μL (without granulocyte colony-stimulating factor support within 2 weeks before cycle 0 day 1).
  • Platelet count ≥ 100.000/μL (without transfusion within 2 weeks before Cycle 0 Day 1).
  • Hemoglobin ≥ 9g/dL (patients may be transfused or receive erythropoietic treatment to meet this criterion).
  • Total bilirubin ≤ 1.5 ULN (subjects with documented/suspected Gilbert's disease or liver metastases may be enrolled with bilirubin ≤ 3 × ULN).
  • Aspartate aminotransferase (AST) or Alanine aminotransferase (ALT) ≤ 2.5 x upper normal limit (ULN) or ≤ 5 × ULN in case of liver metastases.
  • Albumin ≥ 28g/L.
  • Serum creatinine ≤ 1.5 x ULN or creatinine clearance ≥ 40mL/min .
  • International normalized ratio and activated partial thromboplastin time ≤ 1.5 x ULN. This applies only to patients who do not receive therapeutic anticoagulation; patients receiving therapeutic anticoagulation (such as low-molecular weight heparin or warfarin) should be on stable dose.
  • Women of childbearing potential must have a negative serum β-HCG pregnancy test within 7 days prior to the administration of the first study treatment
  • Sexually active women of childbearing potential must agree to use a highly effective method of contraception << supplemented by a barrier method >>, or to abstain from sexual activity during the study and for at least 6 months after the last study treatment administration.
  • Sexually active males patients must agree to use condom during the study and for at least 6 months after the last study treatment administration. Also, it is recommended their women of childbearing potential partner use a highly effective method of contraception.
  • A woman is considered of childbearing potential following menarche and until becoming post-menopausal (≥ 12 months of non-therapy-induced amenorrhea) unless permanently sterile. Permanent sterilization methods include hysterectomy, bilateral oophorectomy and bilateral salpingectomy.
  • A highly effective birth control method is a one which can achieve a failure rate of less than 1% per year when used consistently and correctly. Such methods include: combined (estrogen and progesterone containing) hormonal contraception associated with inhibition of ovulation; progestogen-only hormonal contraception associated with inhibition of ovulation; intrauterine device (IUD); intrauterine hormone-releasing system (IUS); bilateral tubal occlusion; vasectomized partner (on the understanding that this is the only one partner during the whole study duration), and sexual abstinence during the entire period of risk associated with study treatment. To prevent the risk of interaction between the study drug and hormonal contraceptives, hormonal contraceptives should be supplemented with a barrier method (preferably male condom). Following methods are considered as unacceptable methods (non-exhaustive list): periodic abstinence (calendar, symptothermal, post-ovulation methods) and withdrawal (coitus interruptus).
  • Patient should understand, sign, and date the written informed consent form prior to any protocol-specific procedures performed.
  • Patient should be able and willing to comply with study visits and procedures as per protocol.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Atezolizumab and Rucaparib in people with Solid Tumor, run by Gustave Roussy, Cancer Campus, Grand Paris at 1 site in France.

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 81 inclusion and 0 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: stopped early, as of the sponsor's last update on 1 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. 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?

The study was stopped early (reason given: Bankruptcy of partner: Clovis). Results are not available in the source record.

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?

Overall Response Rate (time frame: at 12 weeks). 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 NCT04276376.

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 1 Dec 2025.
