Clinical Trial Summary

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).

Recruitment information / eligibility

• Status: Active, not recruiting
• Enrollment: 180
• Est. completion date: November 2022
• Est. primary completion date: April 2022
• Accepts healthy volunteers: No
• Gender: Male
• Age group: 18 Years and older

Eligibility

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

• ECOG performance status =2.

• Laboratory values obtained =30 days prior to first vaccination: Hemoglobin =5.6 mmol/L; Absolute granulocyte count =1.5 x 109 /L, Platelets =100 x 109 /L., Total bilirubin =1.5 x upper limit of normal (ULN).

• Creatinine =1.5 x ULN.

• Alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) =2.5 x ULN.

Main Exclusion Criteria:

• Patients who are receiving androgen-deprivation therapy or considered a candidate for immediate anti-androgen deprivation therapy (ADT) as judged by the investigator.

• Patients who have received prior ADT are not eligible with the exception of those that received ADT =36 months in duration and =9 months before randomization and administered only in the neoadjuvant/adjuvant setting.

• Patient is planned for salvage therapy with RT or radical prostatectomy.

• Castrate level of serum testosterone <50 ng/dL at screening.

• PSA >10 ng/mL

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Time to PSA progression	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	Safety by frequency and severity of adverse events (AEs)	The numbers and proportions of patients with any treatment-emergent adverse event (TEAE), and any serious TEAE will be summarized	Up to 16 months
Secondary	Time to initiation of a subsequent antineoplastic therapy		Up to 3 years
Secondary	Proportion of patients showing a PSA response from baseline		Up to 3 years
Secondary	Disease-free survival (DFS)	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
