About this study

Official title: A Phase 2, Multicenter, Single-Arm Trial of CV301 in Combination With PD-1/L1 Blockade in Patients With Locally Advanced or Metastatic Urothelial Bladder Cancer

This is a Phase 2, single-arm, multi-institutional clinical trial designed to study the combination of CV301 with atezolizumab in the first-line treatment of UC not eligible for cisplatin-containing chemotherapy (Cohort 1) and in the second-line treatment of UC previously treated with standard first-line cisplatin-based chemotherapy (Cohort 2).

Read the detailed description

This is a Phase 2, single-arm, multi-institutional clinical trial designed to study the combination of CV301 with atezolizumab in the first-line treatment of UC not eligible for cisplatin-containing chemotherapy (Cohort 1) and in the second-line treatment of UC previously treated with standard first-line cisplatin-based chemotherapy (Cohort 2). The trial will be performed using an optimal two-stage design within each cohort.

Stage 1, Cohort 1: Enroll 14 subjects. If objective response is not achieved in at least four patients, the cohort will be stopped for futility. If objective response is achieved in at least four subjects, the cohort will proceed to stage 2. If any patient is not evaluable for the primary endpoint, the patient may be replaced.

Stage 1, Cohort 2: Enroll 13 subjects. If objective response is not achieved in at least three patients, the cohort will be stopped for futility. If objective response is achieved in at least three subjects, the cohort will proceed to stage 2. If any patient is not evaluable for the primary endpoint, the patient may be replaced.

Stage 2, Cohort 1: Enroll an additional 19 subjects. If any patient is not evaluable for the primary endpoint, the patient may be replaced until a total of 33 patients are evaluable for the primary endpoint.

Stage 2, Cohort 2: Enroll an additional 22 subjects. If any patient is not evaluable for the primary endpoint, the patient may be replaced until a total of 35 patients are evaluable for the primary endpoint.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Objective Response Rate (ORR)

    ORR is the proportion of subjects in the analysis population with a Complete Response (CR) or Partial Response (PR) based on best overall RECIST v1.1 evaluations as performed by the investigator. According to RECIST v1.1, the sum of the longest diameters of non-nodal target lesions and short axis of nodal target lesions are used to evaluate tumor response. Maximum of 2 target lesions per organ and 5 target lesions are used for the measurement. CR means disappearance of all known disease, confirmed at 4 week, lymph nodes must be < 10 mm short axis. PR means >=30% decrease from baseline measurement, confirmed at 4 week.

    Measured: up to 24 months

Secondary outcomes (10)

  1. Progression Free Survival (PFS)

    The time interval from first treatment to objective tumor progression or death of any cause. Subjects without death or progression are censored at the date when the last assessment determined a lack of progression. The time interval from first vaccination to death of any cause, up to 4 years for each subject or discontinuation of the study by sponsor.

    Measured: The time from day of first treatment to the start of disease progression or death, whichever occurs first, or the last assessment date if there is a lack of progression, up to 24 months for each subject or discontinuation of the study by sponsor.

  2. Overall Survival (OS)

    Time interval from first treatment to death of any cause. Subjects are censored at their date of last contact if they did not meet the survival endpoint by the outcome measure time frame.

    Measured: The time interval from first vaccination to death of any cause, up to 24 months for each subject or discontinuation of the study by sponsor.

  3. Duration of Response

    The time from objective response (CR or PR, whichever comes first) to investigator assessed progression using RECIST v1.1 or death

    Measured: up to 24 months

  4. Treatment-Emergent Adverse Events

    An Overall Summary of Subjects with any Treatment-Emergent Adverse Events (TEAEs) and TEAEs Categories. TEAEs Categories include Related Adverse Events, >=Grade 3 Adverse Events, Related >= Grade 3 Adverse Events, Serious Adverse Events, Related Serious Adverse Events, Adverse Events of Special Interest and Related Adverse Events of Special Interest. TEAEs are considered as related when the investigator-assessed relationship of the corresponding trial treatment is "possible", "probable", "definite" or missing. Per CTCAE v5, Grade 1=Mild; asymptomatic or mild symptoms. Grade 2=Moderate; minimal, local or noninvasive intervention indicated. Grade 3=Severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated. Grade 4=Life-threatening consequences; urgent intervention indicated. Grade 5=Death related to AE. Immune Mediated Adverse Events (IMAE) and Cardiac events are considered AESIs.

    Measured: up to 24 months

  5. Toxicity Grade Shift From Baseline in Laboratory Results

    Toxicity grades are based on CTCAE v5 scales for hematology and chemistry laboratory parameters. Grade 0=Normal, Grade 1=Mild, Grade 2=Moderate, Grade 3=Severe, Grade 5=Life-threatening, and Grade 5=Death. Toxicity grade shift is defined to evaluate categorical changes from baseline results to post-treatment results with respect to dichotomized CTCAE v5 grading value (<= Grade 2, >= Grade 3).

    Measured: Overall Study up to 24 months

  6. Vital Signs Results - Pulse Rate

    Vital signs results assessed throughout the study.

    Measured: Overall study up to 24 months

  7. Vital Signs Results - System Blood Pressure

    Vital signs results assessed throughout the study.

    Measured: Overall study up to 24 months

  8. Vital Signs Results - Diastolic Blood Pressure

    Vital signs results assessed throughout the study.

    Measured: Overall study up to 24 months

  9. Vital Signs Results - Temperature

    Vital signs results assessed throughout the study.

    Measured: Overall study up to 24 months

  10. Vital Signs Results - Respiratory Rate

    Vital signs results assessed throughout the study.

    Measured: Overall study up to 24 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing CV301 and Atezolizumab in people with Bladder Cancer, run by Bavarian Nordic at 6 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 21 inclusion and 44 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 27 Apr 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 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 27 Apr 2022). 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?

Objective Response Rate (ORR) (time frame: up to 24 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 NCT03628716.

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 27 Apr 2022.
