Study of RV001V in Biochemical Failure Following Curatively Intended Therapy For Localized Prostate Cancer (BRaVac)

September 27, 2021 updated by: RhoVac APS

A Phase 2, Double-Blind, Placebo Controlled Study of RV001V in Men With Biochemical Failure Following Curatively Intended Therapy For Localized Prostate Cancer (BRaVac)

This Phase II trial will enroll approximately 180 adult male patients with an earlier histologic diagnosis of prostatic adenocarcinoma and a biochemical recurrence (BCR) within 3 years of radical prostatectomy (RP) or definitive RT and no distant metastasis or locoregional recurrence. The trial is a randomized placebo-controlled double-blind study of a peptide cancer vaccine (RV001V).

Phase

Phase

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

Main Inclusion Criteria:

  • Biochemical recurrence (BCR) within 3 years of radical prostatectomy (RP) or definitive RT and no distant metastasis by standard CT imaging and bone scintigraphy, or locoregional recurrence (including lymph nodes) assessed by CT or multi-parametric magnetic resonance imaging (MRI) and confirmed with negative biopsy in case of prior RT.
  • In case of BCR after RP all the following criteria should apply: a. PSA ≥0.2 ng/mL, b. PSA Doubling Time (PSADT) >3 months and <12 months
  • In case of BCR after RT all the following criteria should apply: a. PSA >nadir + 2 ng/mL, b. PSADT >3 months and <12 months

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Time to PSA progression
Time Frame: Up to 3 years
Time to PSA progression is defined as the time from randomization to doubling of PSA from the baseline value. The time to doubling will be estimated from a log-linear regression of PSA values.
Up to 3 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Safety by frequency and severity of adverse events (AEs)
Time Frame: Up to 16 months
The numbers and proportions of patients with any treatment-emergent adverse event (TEAE), and any serious TEAE will be summarized
Up to 16 months
Time to initiation of a subsequent antineoplastic therapy
Time Frame: Up to 3 years
Up to 3 years
Proportion of patients showing a PSA response from baseline
Time Frame: Up to 3 years
Up to 3 years
Disease-free survival (DFS)
Time Frame: Up to 3 years
time from randomization to documented clinical recurrence (distant or local), or death from any cause, censoring at date of last follow-up (FU)
Up to 3 years

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
